Key takeaways:

• • • Prompt engineering pays off 鈥� Tax professionals who master clear, contextualized AI instructions see immediate gains in output quality and speed.

    • AI doesn鈥檛 replace professional responsibility 鈥� Every output that carries your name requires your verification and your judgment.

    • Link learning to a real problem 鈥� The most effective way to build needed skills is to focus on your current workflow, not to chase every new tool as it emerges.

For tax professionals, technical excellence used to be enough. Know the code, understand the cases, apply the rules correctly 鈥� that was the job, and it was sufficient. It isn’t anymore. Not because the technical knowledge matters less, but because the professionals competing for the same work increasingly bring other talents to the table, such as the ability to do in an hour what used to take a day; to provide insights from data that would have taken a week to compile manually; and to deliver polished, well-reasoned analysis at a pace that wasn’t possible five years ago.

This rarified capability doesn’t come from intelligence or experience alone; rather, it comes from skills 鈥� specific, learnable, practical skills.

The data bears this out. Improving efficiency through technology has been the top strategic priority for firms for three consecutive years, with 44% of firm leaders citing it as their primary focus, according to the 成人VR视频 Institute鈥檚 . Indeed, 47% of tax professionals surveyed said investing in AI should now be a top priority 鈥� and yet, 18% of firms still use no automation at all.

This gap between intention and capability is real, and it sits squarely with the individual tax professional.

The skills most needed by today鈥檚 tax professionals

To help close this gap and improve tax professionals鈥� overall work value, there are several specific skills that demand attention, including:

Prompt engineering: The skill nobody takes seriously until they see what it does

The name doesn’t help 鈥� but set that aside, because the underlying skill is straightforward: giving your AI tools clear, precise, well-contextualized instructions that produce outputs that are worth using.

Most people start badly when approaching a blank AI screen. They type something vague, get something generic, and conclude the tool isn’t useful. That conclusion is wrong, because it was the instructions given, the prompt, that was the problem. Specify the entity type, jurisdiction, tax year, audience, and format. Then tell the tool what you need and why. The difference in output quality is not marginal.

Of course, it鈥檚 important to remember that AI will tell you things that are wrong with complete confidence. It will cite an amended provision, apply a rule from the wrong jurisdiction, or construct a plausible analysis on a flawed premise 鈥� all without flagging any of it. The professional responsibility to catch it remains entirely upon the user. That’s not a flaw in the tool; it’s a reminder that expertise isn’t being replaced here 鈥� it’s being put to better use.

Data literacy: The capability gap most tax professionals don’t know they have

Tax work is data work. Today, what has changed is the expectations around the volume and complexity that professionals are now required to handle, interpret, and present, often with fewer resources than a decade ago.

Advanced spreadsheet proficiency is the starting point, and the emphasis on advanced is deliberate. The features that most professionals have never explored are precisely the ones that separate those who spend three hours processing data from those who spend 20 minutes. The ability to build visual dashboards that communicate tax data clearly 鈥� effective tax rates, provision variances, deferred movements, and more 鈥� is increasingly an expectation in corporate environments rather than a differentiator. For those professionals who handle large datasets or complex scenario modeling, even a foundational understanding of represents a significant capability uplift.

The Tax Professionals Report found that 57% of firm leaders cited getting better use out of existing technology as their top investment priority 鈥� more than those planning to buy new systems. The problem, in other words, isn’t the tools; it鈥檚 having the skills and the understanding to use them.

Workflow automation: Reclaiming time from work that shouldn’t exist

Look at any tax workflow closely and you’ll find steps that are repetitive, rule-based, and time-consuming 鈥� not because they require a tax professional鈥檚 skilled judgment, but because nobody has stopped to ask whether these routine tasks could be done differently.

Again, the harder part of improving your skill set as a tax professional isn’t learning the tools; rather, it’s developing the habit of process analysis, a way of thinking that will allow you (among other things) to distinguish between steps that require genuine expertise and steps that are simply consuming time.

AI judgment: Knowing what to trust and what to verify

This is the skill that determines whether AI makes you more effective or creates problems you didn’t anticipate. This means validating outputs against primary sources before they reach a client. It means recognizing that AI reflects training data that may be outdated or jurisdiction-specific in ways that aren’t readily apparent in the output. And it means knowing when a task is too nuanced or too high stakes for AI to handle reliably.

Professional responsibility does not transfer to the tool itself. If an AI-generated analysis carries your name, it is your analysis.

Communicating and staying current

As routine tax compliance work becomes more automated, the premium on communication rises sharply. The Tax Professionals Report found that three-quarters of clients now strongly desire advisory services beyond tax preparation from their outside tax professional 鈥� yet most tax firms still derive their greatest profits from simple tax return preparation.

Those professionals who can close that gap are those who can translate technical work into clear, confident guidance that their clients can act on.

Going forward, the tools will keep changing. Identify the problem in your current workflow that costs the most time, find the skill that addresses it, and build from there. The professionals who will define the next decade will combine this deep technical knowledge with the ability to work faster, more clearly, and more adaptively than those who came before them. That combination is not yet common, but it鈥檚 also not out of reach.

Key takeaways:

• • • Your post-OBBBA forecasts should look different 鈥� If the tax department doesn’t own the OBBBA model, someone else will own the OBBBA story.

• • • Rely on your department鈥檚 inner strengths 鈥� It鈥檚 governance and analysis 鈥� not tools 鈥� that get you into the strategy room.

    • Factor in the conflict in the Middle East 鈥� The Iran war risk belongs in your tax model, not just in your CFO’s macro deck.

The One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, enacted large business tax cuts, most notably by providing permanent full expensing of many forms of investment. Under the previous major corporate tax legislation, 2017鈥檚 Tax Cuts and Jobs Act (TCJA), bonus depreciation was scheduled for gradual phase-out following 2023. The OBBBA restored that expensing 100% retroactively for assets acquired from mid-January 2025 onwards.

The after-tax cost of new machinery, fleets, and equipment has effectively fallen by around 21%, designed to encourage immediate capital outlays by allowing businesses to write off these expenses in the year they are incurred rather than amortizing them over five years.

For corporate tax departments, that’s not a disclosure footnote 鈥� that’s your capital plan.

Capital-intensive corporations will see tax burdens reduced through permanent rate extensions, depreciation adjustments, and expansion of the state and local tax (SALT) deduction cap 鈥� but only if your models are built to capture the timing and location of investment, the mix of debt compared to equity, and where your organization books its next dollar of income.

Not surprisingly, most corporate tax departments aren’t there yet. They’re still recalculating last year, plus a few adjustments. That’s glorified compliance, not modeling.

A standout tax department doesn’t ask, What’s the OBBBA impact? Rather, it asks, Which version of OBBBA do we choose for this business? 鈥� and it has the models to back it up.

From spreadsheet heroics to controlled modeling

For many organizations, tax modeling still means creating a massive spreadsheet that only one director truly understands. The spreadsheet gets pulled out for budget season, rebuilt under pressure, and quietly retired until next year. That’s a single point of failure, not a process.

And after OBBBA, continuing that practice is dangerous. One wrong assumption on expensing or interest limitation can move cash tax by millions of dollars and blindside the Finance Department.

Here’s what disciplined modeling looks like in practice:

• • • Create a unified model 鈥� Build one integrated model that the whole team can use or accept that your department is choosing to fly blind.
    • Use the same assumptions 鈥� Standardize the levers that matter most (such as capex timing, financing mix, jurisdiction, and incentives) and make sure every scenario runs off the same assumptions.
    • Conduct modeling reviews 鈥� Treat major OBBBA-driven decisions (such as large capex, funding shifts, supply-chain redesign) as tax deals that must go through a modeling review before they’re greenlit.
    • Document your assumptions explicitly 鈥� Under permanent full expensing, the difference between a well-supported assumption and a poorly documented one isn’t just an audit risk, rather it’s a credibility problem with your CFO.

It鈥檚 also important to remember that in a post-OBBBA world, this level of disciplined modeling is not technology transformation 鈥� it鈥檚 basic survival.

Governance: Where leaders quietly win or loudly fail

The differentiator isn’t which corporate tax department has the fanciest tool 鈥� it’s which one has the cleanest governance. And the data is unambiguous: More than half (55%) of tax departments are still in the reactive phase of their technological development, stuck with five capex models circulating with five discount rates and the tax team arriving late to the planning meeting.

Those tax departments that are breaking out of that pattern share one trait: They put someone formally in charge. In the 成人VR视频 Institute鈥檚 recent 2026 Corporate Tax Department Technology Report, a large portion (88%) of survey respondents said their company had appointed a person to lead the tax department’s technology strategy. That number jumped a whopping 37 percentage points, from 51%, from the previous year鈥檚 survey. That single structural move separates those departments with a governance model from those that simply hold a governance conversation every budget cycle and forget about it.

Clearly, this type of ownership drives results. Two-thirds of those surveyed agreed that their company’s investment in technology has enabled a shift from routine, reactive work to more strategic, proactive, higher-value work.

Under OBBBA, the kind of governance isn’t housekeeping. It’s how you get invited into strategy discussions instead of having to clean up after things go awry.

Why your OBBBA win may not feel like a win

On paper, the tax changes embedded in the OBBBA look generous. In practice, your effective tax benefit is colliding with something you don’t control.

When the war on Iran began, all shipping through the Strait of Hormuz was effectively halted, removing roughly one-fifth of the world’s oil and gas supply from the market. Fuel prices throughout the world spiked and are likely to remain elevated as long as conflict persists.

With oil prices hovering around $100 a barrel, there are will wipe out the benefits of higher tax refunds this year for most Americans. If those benefits, arising from Trump’s 2025 tax cuts, are erased for the average American, only the top 30% of taxpayers will still seeing a net gain.

For corporate planning purposes, the parallel dynamic is real: The topline OBBBA benefit is being eroded by higher fuel, freight, and financing costs across the business and its supply chain.

Inflationary pressures are being driven by higher energy prices tied to the Iran war, and the conflict’s impact on a wide range of goods and services is likely to last for months 鈥� with experts saying even a ceasefire is unlikely to immediately ease global energy shortages.

A serious corporate tax department doesn’t handwave these concerns away. It takes three actions:

1. 1. 1. Run a war-extended scenario 鈥� The scenario should show exactly how sustained higher energy costs and borrowing rates change the payoff from accelerated expensing and leverage 鈥� with specific numbers, not just directional commentary.
      2. Share your forecasts internally 鈥� Put your monthly or quarterly cash-tax forecasts on the table for Finance to see, so that it can manage liquidity rather than hope the annual plan holds.
      3. Force the hard conversation 鈥� Ask the tough question: At today’s rates and fuel costs, the after-tax return on this project is X. Are we still in? That question should come from the tax team now, not from the finance team six months later.

Clearly, the daily fluctuations in oil prices matter less than monthly and quarterly averages 鈥� and volatility will likely remain elevated given the absence of a clear timeline for the end of the war. That’s exactly the kind of sustained uncertainty that belongs front and center in your scenario set, not in a footnote.

The bottom line

The OBBBA gives corporate tax departments a genuine opportunity to move from being simply a compliance function to becoming more of a strategic advisor. Permanent full expensing, richer cost recovery, and more flexible interest rules can create real levers to add value, but only for those organizations that model them rigorously, govern them cleanly, and stress-test them against the macro environment their business actually faces today.

Indeed, the Iran war is a live test of that readiness. The corporate tax departments that show up with modeled scenarios, cash-tax forecasts, and a clear point of view on after-tax returns will earn a seat at the strategy table. The ones that show up with caveats will be asked to leave it.

• • • Changing the balance of taxes 鈥� Budget鈥慸riven tax swaps and incentive reforms are changing the balance between income, property, and sales taxes, forcing large companies to revisit their multistate footprint.

    • How revenue is sourced is changing, too 鈥� Rapidly evolving digital and AI鈥憆elated taxes are creating new nexus, sourcing, and base鈥慸efinition issues for businesses that rely on revenue from digital advertising, social platforms, data monetization, and automated tools.

    • Planning amid continued uncertainty 鈥� New federal tax regulations, tariff鈥憆elated uncertainty, and even the elimination of the penny are all amplifying state鈥慴y鈥憇tate complexity for in鈥慼ouse tax departments.

WASHINGTON, DC 鈥� Tax industry experts who gathered at to provide updates on the current landscape of state and local tax (SALT) policy and offer insight that corporate tax departments should consider found, not surprisingly, that they had a lot to talk about in the current economic environment.

Mapping the new SALT frontier

For starters, this year鈥檚 SALT agenda is not just an abstract policy story for large, multistate businesses, rather, it鈥檚 a direct driver of cash taxes, effective tax rate (ETR) volatility, and audit exposure. Indeed, several state legislatures are advancing new taxes on digital advertising and data, revisiting incentives and data center exemptions, and using conformity to federal law 鈥� especially the tax provisions in the One Big Beautiful Bill Act (OBBBA) 鈥� as a policy lever, all against the backdrop of slowing revenues and contentious elections.

鈥淭ax swaps鈥� and incentives 鈥� States that are facing budget pressure are, unsurprisingly, looking at tax swaps to reduce income or property taxes while broadening the sales & use tax base and trimming exemptions. For example, on March 3, the state of Florida 鈥� which already doesn鈥檛 have a state income tax 鈥� passed legislation that in the state.

Moreover, with the rapid expansion of AI come the extensive need for data centers. Several states are reassessing data center exemptions and credits, either tightening qualification standards, requiring centers to supply more of their own power, or repealing incentives outright. A decision in Virginia to , for example, is viewed as a potential template for other states, particularly in those areas in which energy and environmental concerns are priorities. At the same time, proposals targeting include expanded corporate tax disclosures, CEO compensation surcharges, and enhanced reporting on apportionment and group filing methods.

What companies should consider 鈥� Large companies operating over multiple states should consider making an inventory of their credits and incentives by jurisdiction, including looking at sunset dates and political risk indicators.

Companies should also build forward鈥憀ooking models that show how any sales tax base expansion would interact with their supply chain and their procurement of digital and professional services.

New exposure for tech, marketing & data

Bipartisan legislators in several states are continuing to expand on digital economies as a revenue and policy target. For example, Maryland continues to lead with its digital advertising tax; while Washington state鈥檚 expansion of its sales tax to include certain digital and IT services and Chicago鈥檚 social media taxes illustrate the variety of approaches that state and local jurisdictions are exploring to expand their tax base and raise revenue.

Data and 鈥渄igital resource鈥� taxes 鈥� Proposals in states such as New York would tax companies that derive income from resident data, treating data as a natural resource. While no state has fully implemented a comprehensive data tax, however, large platforms and data鈥慸riven enterprises are monitoring these bills closely.

AI鈥憆elated SALT rules 鈥� Many states still classify AI solutions under existing Software as a Service (SaaS) or data鈥憄rocessing categories, but some 鈥� including New York 鈥� are exploring surcharges tied to AI鈥慸riven workforce reductions. And at least two states are explicitly taxing AI, similarly to the way software is taxed.

For corporate tax leaders, some practical next steps should include mapping those areas in which your group has digital ad spending, user bases, data monetization, or AI deployments. Then, overlaying that with current and pending digital tax proposals. In parallel, it is increasingly critical for the tax team to partner with IT and marketing teams to understand how contracts, invoicing structures, and platform design will affect nexus, tax base definition, and sourcing.

Federal shifts magnify multistate complexity

The OBBBA made permanent several of , while expanding SALT relief on the individual side and creating new interactions for multinational groups. Because most states start from federal taxable income 鈥� either on a rolling, static, or selective conformity basis 鈥� OBBBA changes reverberate across state corporate income tax bases, especially in those states that have decoupled themselves from interest limits, R&D expensing, or new production鈥憆elated incentives.

Corporate tax departments must now juggle different conformity dates and selective decoupling rules across rolling and static states, including jurisdictions that automatically decouple when a federal change exceeds a revenue impact threshold. This requires more granular state鈥慴y鈥憇tate modeling of OBBBA impacts on apportionable income, deferred tax balances, and cash tax forecasts. It also heightens the risk that political disputes 鈥� such as 鈥� produce mid鈥慶ycle changes that complicate provision and compliance processes.

Penny elimination 鈥� With federal , states now are moving toward symmetrical rounding for cash transactions, rounding the final tax鈥慽nclusive total to the nearest five cents while attempting not to alter the underlying tax computation. For retailers and consumer鈥慺acing enterprises, this shifts the focus to point of sale (POS) configuration, consumer鈥憄rotection exposure, and class鈥慳ction risk if rounding is implemented incorrectly.

Tariffs and refunds 鈥� The U.S. Supreme Court鈥檚 Learning Resources, Inc. v. Trump decision under the International Emergency Economic Powers Act in February leaves open how more than $100 billion in and what that means for prior sales & use tax treatment. Streamlined guidance generally treats tariffs embedded in product prices as part of the taxable sales price but excludes tariffs paid directly by a consumer鈥慽mporter from the tax base, raising complex questions if tariff refunds reduce costs or sales prices retroactively.

For indirect tax department teams, the confluency of the 2026 SALT changes 鈥� including the impacts around everything from data center credits to the recent Supreme Court tariff decision 鈥� the need to rely on internal partners across the business has never been stronger. Combining that with a greater reliance on technologies, including dedicated research tools to stay abreast of state-by-state tax changes, may be the best way for corporate tax teams to keep up with compliance requirements and avoid penalties.

Key takeaways:

• • • Ways of achieving growth has changed 鈥� Sustainable growth now depends less on raw revenue and more on improving income per partner through smarter leverage, intentional service mix, and disciplined pricing.

    • Proactive firms will be better positioned 鈥� Firms that adopt data-driven pricing, bundled offerings, and subscription models will be better positioned to communicate value, raise fees confidently, and protect margins.

    • Differentiators are shifting 鈥� Leadership depth, culture, and succession planning are emerging as decisive differentiators as demographics shift, private equity reshapes the tax market, and next-generation partners step into control.

Tax, audit & accounting firms are still growing, but not all that growth is reaching the bottom line 鈥� indeed, 2026 is shaping up as a separate or be separated moment for many tax firm leaders. To sustain income per partner while the market shifts, firm leaders need to be far more intentional about how they grow, price, staff, and position their tax practices.

Here are five important ways that tax firm leaders can ensure their bottom-line growth keep pace with their top-line revenue:

1. Be deliberate about how you grow

Revenue is rising, but margins are under pressure. For example, for firms with revenue of more than $2 million, revenue grew 7.9%, yet income per equity partner (IPP) increased only 3.2%. This may imply that although firms are bringing in more money, the remaining profits available to distribute to equity partners isn鈥檛 growing at the same rate. This could mean that it鈥檚 costing firms more to generate more revenue possibly because expenses are eating into margins.

Meanwhile, 13.9% of total growth for firms whose revenue is more than $2 million now comes from mergers, and for firms with revenue of more than $20 million, more than one-fifth of growth is merger-driven.

For growth strategy, leaders should clarify their organic growth plans in light of this robust M&A drive, deciding when acquisitions are truly about capacity, specialization, or geography and when they are merely propping up lagging organic growth.

Leaders need to protect IPP metrics by focusing relentlessly on revenue per partner and revenue per person as primary levers, rather than chasing top-line growth for its own sake. Leaders also need to build optionality 鈥� with private equity, mega-firm consolidators, and independents all active, factors such as succession, capital, and ownership design have become core strategic decisions that can no longer be left to chance.

2. Treat pricing as a growth discipline

In the 成人VR视频 Institute’s pricing report for tax, audit & accounting firms, 64% of decision-makers said their firms saw revenue increases, but only 45% reported increased profits 鈥� a clear indication of margin compression. Further, just about 1-in-5 professionals said they feel 鈥渉ighly confident鈥� that their firm鈥檚 current pricing reflects the expertise of its professionals.

To be sure, key pricing work now involves moving beyond what the market will bear. While hourly billing still dominates (according to the report firms said over 40% of client engagements are billed on an hourly basis) 鈥� value-aligned methods such as fixed fees, subscriptions, and bundled packages are strongly associated with higher pricing confidence and a firm’s greater ability to raise fees.

To excel in this area, tax firm leaders need to use data rather than their gut. Although only 30% of respondents said their firm regularly benchmark their pricing against competitors, leaders overwhelmingly say better market intelligence would increase pricing confidence. Also, firms should expand subscription and bundle pricing options, since respondents form subscription-billing firms report significantly higher confidence that their pricing reflects value. Indeed, many firms using bundled packages have raised prices 10% to 24% or more over the past two years.

3. Build a capacity model that scales

The Rosenberg data is blunt: The fastest path to higher income per partner is not logging more partner hours 鈥� it is using smart leverage and stronger rates. Elite tax firms (those with IPP above $800,000) generate roughly $3.9 million in revenue per equity partner and maintain staff-to-partner ratios of around 17:1.

Several capacity dynamics matter in practice. Leverage drives profitability, for example, and those firms that have staff-to-partner ratios above 10 report IPP roughly double that of firms with ratios below 3, even though they may carry higher salary percentages.

Further, outsourcing has become mainstream. More than 4-in-10 firms (42%) with more than $2 million in revenue now outsource full-time equivalent (FTEs) employees, a figure that rises to 63% among firms with more than $ 20 million dollars. Interestingly, turnover has eased to about 11%, the lowest for the industry in years, but expectations have shifted as firms intentionally reduce average billable hours per staff member to prioritize sustainable workloads.

In fact, the key growth question is no longer Can we find the work? but rather Can we design a capacity model 鈥� onshore, offshore, AI-enabled 鈥� that supports higher rates without burning out our people?

4. Formalize strategy, marketing & service mix

Firms with written strategic plans earn about 4.5% more IPP than those without, according to the data, and firms with a formal marketing plan enjoy about 9% higher IPP. The most profitable firms are also more intentional about service mix, tilting toward advisory and financial services.

Growth-enabling practices start with written strategic and marketing plans. Firms that document these plans consistently outperform their peers, particularly when navigating private equity interest, AI adoption, and succession decisions. Many leading tax firms are deliberately shifting from compliance to advisory, reducing their reliance on commodity tax compliance and expanding into higher-value advisory work to drive stronger profitability. These firms are also packaging and communicating value more effectively by bundling compliance and advisory services into tiered packages, which in turn gives them greater ability to raise fees and justify premium positioning in the market.

5. Invest in leadership, culture & succession

Growth without leadership depth is fragile, especially in the tax profession in which the average partner age has remained high. Most recently, however, the average partner age has dipped slightly to about 52 years old as more retirements occur. And female partners now account for roughly one-quarter of partner groups overall, showing progress but also a persistent equity gap.

For many firms, succession remains a primary concern, and leadership-related growth priorities begin with treating succession as strategy, not an HR project. More firms are revisiting buy-in levels, which average around $133,000, and are experimenting with non-equity roles and alternative practice structures to create more flexible pathways to ownership. At the same time, leaders must protect and modernize their firm culture, recognizing that poorly managed PE transactions, rigid return-to-office policies, and underinvestment in technology-forward talent can quickly erode the very engines of growth they depend on.

Additionally, firms are elevating the managing partner role. In larger practices, managing partners鈥� chargeable hours are now meaningfully lower, reflecting an intentional shift toward having that role work on the business 鈥� strategy, talent, pricing, and M&A 鈥� rather than in it.

For tax firm leaders, these five considerations form a practical checklist for 2026 planning. Grounding each strategic initiative in data and taking visible action can help ensure that the next wave of growth shows up not just in revenue, but in sustainable, rising income per partner.

Key takeaways:

• • • Data is your foundation, not AI 鈥� Before investing in AI tools, corporate tax departments are finding they need to centralize and automate their data across multiple ERP systems because clean, accessible data often determines whether technology implementations succeed or create additional problems.

    • Compliance is becoming commoditized 鈥� Specialization creates differentiation, and tax firms are discovering they can no longer differentiate themselves through basic compliance work that technology can complete in seconds. That means that successful practices are going deep into emerging fields like crypto, providing strategic insights that generic practices can’t match.

    • Learning to tell the story behind the numbers 鈥� A valuable skill for in-house tax professionals is becoming data fluent enough to analyze outputs and communicate tax implications to non-tax stakeholders. This ability to translate complexity into actionable business advice can transform your tax department from a cost center into a strategic partner.

If you’re spending most of your week on manual data entry and routine compliance work, you’ve likely noticed the ground shifting beneath the tax, audit & accounting profession. The work that defines value in tax is changing and has been for a while, and now more and more tax professionals are grappling with what that means for their careers.

What’s becoming clear for both corporate tax departments and tax firms is that 2026 represents a pivotal year 鈥� not because of arbitrary deadlines, but because the gap between traditional approaches and emerging practices is widening.

The corporate tax department: From compliance factory to strategic engine

For those in corporate tax departments, strategic work is increasingly becoming non-optional. Supply chain decisions, tariff implications, global compliance complexity 鈥� these are landing on the desks of in-house tax team members as core responsibilities rather than occasional advisory projects.

What’s emerging in leading tax departments? Three patterns: intelligence, automation, and agility.

The data challenge comes first 鈥� Many departments are discovering that before implementing AI strategies or automation roadmaps, they need to address their data infrastructure. Data often lives across multiple enterprise resource planning (ERP) systems, requires manual transfers between systems, and needs hours of reconciliation before it’s usable.

This foundational issue frequently determines whether technology implementations succeed or fail. Data dictates what’s possible with any technology, especially AI. For most organizations, it remains a vulnerability despite being a critical component of modern tax departments.

Supply chain decisions, tariff implications, global compliance complexity 鈥� these are landing on the desks of in-house tax team members as core responsibilities rather than occasional advisory projects.

Getting data centralized, automated, and accessible 鈥� and ideally aligned with the broader corporate finance department 鈥� may not make for exciting presentations to leadership, but it’s often the difference between technology that transforms a department and technology that creates additional work.

Technology decisions benefit from intentionality 鈥� AI is being marketed as a universal solution, but experienced professionals are finding it works best when applied to clearly defined problems. Before purchasing another platform or piloting another tool, successful tax departments are asking what they’re actually trying to accomplish with the technology. Which processes should be automated first? Does AI make sense for this particular challenge?

Productive conversations with organizations鈥� IT departments, understanding current technology stack capabilities, and mapping problems before seeking solutions 鈥� these approaches tend to matter more than the sophistication of the acquired tools themselves.

Certain skills are becoming increasingly valuable 鈥� You don’t necessarily need to become a data scientist, but technological and AI fluency is proving to be an essential skill. Think of it as learning another language 鈥� you need enough of a command of it to communicate effectively and understand what you’re looking at.

The ability to analyze data outputs, spot patterns, and tell the story of what the data means is separating strategic tax professionals from those who are focused primarily on compliance. Being able to communicate tax information to non-tax professionals and then translate complex implications into actionable business advice will position you and your department as a strategic partner rather than a cost center.

As the complexity of tax regulations continues to expand, both globally and locally, many in-house tax departments are finding they need to automate routine work and leverage technology not just for compliance, but to predict outcomes and advise the business strategically.

The tax firm: When compliance becomes commoditized

For tax and accounting firms, the current tech-driven shift is particularly urgent. Compliance work is becoming more and more commoditized, and technology can now complete basic compliance in seconds. Indeed, some financial institutions are offering it for free to attract clients.

Tax professionals still spend roughly 60% of their time on manual, repetitive work, but this model is under pressure. Regulatory authorities are using technology to demand information faster, and clients expect more. Further, competition is intensifying from private equity-backed firms, mergers, and tech-enabled competitors who can deliver compliance work at significantly lower costs.

Several factors that weren’t present before 鈥� such as PE investment, consolidation, technology democratization, and more 鈥� are creating unprecedented competitive pressure and fundamentally changing what distinguishes one tax firm from another.

Automation is becoming table stakes 鈥� Successful tax firms are systematizing and automating compliance work and developing customer relationship management (CRM) strategies for managing client data. This isn’t about eliminating jobs; rather, it’s about eliminating tasks. As mentioned, regulatory authorities are already demanding information faster using their own technology, and firms are finding they need to keep pace.

Several factors that weren’t present before 鈥� such as PE investment, consolidation, technology democratization, and more 鈥� are creating unprecedented competitive pressure and fundamentally changing what distinguishes one tax firm from another.

Specialization is creating differentiation, and as a result, the general tax, audit & accounting practice model is facing challenges. Clients increasingly need professionals who know their industry deeply, understand their specific challenges, and can provide insights beyond generic compliance work.

This often means making choices about where to develop deep expertise. Which industries will you focus on? What emerging areas would be best in which to position yourself? And the growing complexity and expansion of tax regulations actually creates opportunities for professionals who can think strategically about emerging fields.

Cryptocurrency is one example. Cross-border commerce, specific regulatory niches, particular industry verticals 鈥� these are areas in which specialization can create meaningful differentiation for a firm.

The advisor relationship looks different 鈥� Providing value in the tax profession is shifting away from form completion and to analyzing client data and providing deep, insightful guidance. This requires a different kind of client relationship 鈥� one that goes deeper into their operations, understands their business intimately, and positions yourself as a partner in decision-making rather than a vendor handling annual filings.

Again, you don’t need to know how to code but being able to analyze client data points and translate them into strategic insights is proving increasingly valuable.

The bottom line: 2026 is a pivotal year

The tax profession 鈥� on both the corporate and the outside firm sides 鈥� appears to be splitting. Some professionals are automating routine work, developing deep expertise, and positioning themselves as strategic advisors. Others are continuing with manual work and hoping that technology can increasingly make them better and faster.

For many, 2026 is about specialization and using technology to enable it. Yet, it’s also about reflection: If you’re no longer firm or in-house function is no longer primarily a compliance machine, what distinguishes them when compliance becomes commoditized?

Further, the complexity of tax regulations is expanding, and this complexity creates demand for expertise. The professionals and firms that can navigate that complexity, provide genuine insights, and communicate clearly may find themselves more valuable than ever.

This shift is already underway. Many professionals are asking themselves whether they’re positioning themselves for where the profession is heading and how they can best offer their strategic expertise to create value for their clients or organizations.

• • • Technology investment drives PE interest 鈥� Private equity firms provide patient capital for multimillion-dollar technology transformations that traditional partnerships struggle to fund.

    • Strategic focus over expansion 鈥� PE-backed firms are shifting from growth through breadth to growth through depth, eliminating underperforming service lines to concentrate resources on areas where they can win.

    • Competitive pressure is mounting 鈥� While most firms remain uninterested in PE transactions, well-capitalized competitors are pulling ahead in technology capabilities, talent attraction, and market positioning.

A competing accounting firm down the street just acquired its fifth firm this year. Another launched an AI-powered tax platform that can deliver work in hours instead of weeks. And a third is recruiting top talent with equity packages your partnership structure can’t match.

What do they have in common? Private equity backing.

Four years ago, when EisnerAmper announced its deal with TowerBrook Capital Partners 鈥� one of the earliest and largest forays of PE money into the tax, audit & accounting industry 鈥� most practitioners dismissed it as an anomaly. Today, roughly half of the top 25 accounting firms have completed or are pursuing PE transactions. This isn’t a trend 鈥� it’s a fundamental restructuring of the profession.

Why traditional partnerships are losing ground

Consider Citrin Cooperman after New Mountain Capital made its investment in 2021. In four years, Citrin Cooperman has acquired more than 20 accounting firms, expanding to 2,800 professionals across 27 offices. That’s strategic acceleration, not organic growth.

Traditional accounting firm partnerships face a structural problem 鈥� they can’t easily fund multimillion-dollar infrastructure buildouts. When firms need enterprise relationship intelligence systems, unified data architectures, or AI-enabled delivery models, where does the capital for these initiatives come from? Partner contributions? Bank loans? Retained earnings that take years to build up?

PE-backed competitors can deploy patient capital 鈥攎oney designed for long-term technology transformation without immediate return pressure. And the gap between what PE-backed firms can do compared to traditional partnerships is widening.

For example, here’s the efficiency paradox: Partners billing at $500 per hour spend significant time on work that should be automated at a $50-per-hour equivalent cost.

That’s not a cost problem 鈥� it’s a revenue capacity problem.

PE-backed firms liberate high-value talent, so they are then free to pursue high-value work. When automation and AI-driven tools handle the more routine tasks, partners can focus on complex client challenges, strategic advisory, and relationship building.

The strategy shift: Depth over breadth

The most counterintuitive transformation PE brings is the shift in strategic focus. Traditional firms pursue growth through breadth by launching practice areas because clients asked for them or competitors offer them. The result? A dozen service lines, with about half of them underperforming.

Instead, PE firms ask one simple question: Where does your firm have a right to win?

This PE-backed strategy eliminates hobby businesses 鈥� those practice areas that exist because they always have, not because they generate competitive returns. Instead, PE-backed firms concentrate their resources on fewer service lines, focusing on those at which firms genuinely excel. Thus, PE-backed firms are reducing service line breadth while firms鈥� depth and increasing profitability and market share as well.

Private equity firms鈥� interest and investment in the tax, audit & accounting industry isn鈥檛 by happenstance. PE firms have done their due diligence to understand the industry 鈥� and not just from firms鈥� perspective, but from that of their clients too.

PE-backed firms liberate high-value tax talent, so they are then free to pursue high-value work, leaving automation and AI-driven tools to handle the more routine tasks.

Private equity firms have spent millions of dollars studying the accounting industry, not only tax firms including firms鈥� clients, and analyzing competitors. The information they鈥檝e gathered represents a cultural shift that has been taking place 鈥� something that many firms themselves hadn鈥檛 noticed. This shift, from relationship-driven but assumption-based service models to data-informed decision making, has helped PE-backed firms know which services clients value, which delivery models they prefer, and for which services they’ll pay premium rates. That intelligence has become competitive advantage.

Further, PE-backed firms can offer equity incentives to next-generation leaders, which is something traditional partnerships struggle to match. PE-backed firms can provide clear career paths, sophisticated training, and professional development resources. As traditional firms ask young partners to buy in at barely affordable valuations, with unclear leadership paths and outdated technology, PE-backed firms are building employer brands that appeal to professionals who want cutting-edge technology and transparent advancement.

It鈥檚 not surprising which firm attracts the best talent.

The skepticism is real 鈥� and justified

Despite these benefits, the accounting profession remains skeptical. More than half of industry practitioners say PE isn’t on their radar, and another third aren’t interested, according to the recent Tax Firm Growth Report 2025 from the 成人VR视频 Institute.

Their concerns are legitimate. Two-thirds say they believe PE investment will negatively impact firm integrity and independence, according to the report. And these skeptical practitioners say they worry about culture, client relationships, and an emphasis on earnings over service quality.

Clearly, PE ownership does add complexity to auditor independence, regulatory compliance, and risk management. But PE firms are exceptionally risk-averse when investing in professional services, and the last thing they want is bad press or audit scandals. In fact, their risk management frameworks are often more sophisticated than traditional partnerships maintain.

Yet, for accounting firms seeking growth but determined to stay independent, PE partnership isn’t the only path. Employee Stock Ownership Plans (ESOPs) offer tax advantages and an employee ownership structure while maintaining independence. Firms like BDO and Grassi successfully implemented ESOPs to better provide liquidity while keeping control localized. Other alternatives include traditional financing, mergers between equals, minority capital deals, and targeted asset sales. Each has advantages and limitations.

The key insight: All alternatives require deliberate strategic action; and none involve maintaining the status quo or standing still.

The coming crossroads

The accounting profession continues to be at junction, and all firms will have to decide on their next move. PE-backed competitors are pulling ahead in technology utilization, market positioning, and talent acquisition. The opportunity window for firms to respond isn’t infinite.

Firms that delay action risk entering merger agreements or partnerships from weakened positions. Worse, they risk becoming acquisition targets, joining PE-backed platforms on terms dictated by necessity rather than choice.

Winners won’t be determined by capital structure alone, of course 鈥� they’ll be determined by execution speed and strategic clarity. However, PE investment can be a critical enabler in an industry facing unprecedented technological disruption and competitive pressure.

The fundamental question isn’t whether to embrace private equity; rather, it’s whether your firm can achieve necessary transformation speed and scale without it. Every firm leader must answer honestly, urgently, and with clear-eyed assessment of their competitive position and their competitors’ accelerating capabilities.

The profession has changed, and accounting firms have to decide whether they鈥檒l be changing with it, or whether they鈥檒l be changed by it.

Key insights:

• • • Advisory is becoming the strategic core of tax practices 鈥� Tax firms are no longer treating advisory services as an add-on to compliance work but rather as a fundamental driver of business strategy, client relationships, and sustainable revenue growth.

    • Frequent client engagement drives measurably better outcomes 鈥� Professionals from firms that meet with clients quarterly or more frequently report significantly higher satisfaction across every dimension.

    • Technology and capacity are the keys to breaking through barriers 鈥� Firms are rapidly adopting automation to free up their professionals for advisory work, while addressing staff skills gaps through training and strategic hires.

For decades, tax firms built their practices around the predictable calendar of the annual compliance cycle, punctuated by occasional client requests for advice. Over the past five or more years, however, there’s been a seismic shift. Tax advisory services are emerging as the defining strategic function within successful firms, and it鈥檚 being driven mostly by an unprecedented convergence of regulatory complexity, technology capabilities, and evolving client expectations.

2026 Tax Firm Advisory Services Report

As a result, many firm leaders are fundamentally rethinking their business models, reimagining what a tax practice can be as they move from being transactional service providers to becoming more strategic advisors that can guide clients through complex financial decisions year-round.

To delve into this deeper, the 成人VR视频 Institute has published the 2026 Tax Firm Advisory Services Report, that clearly shows that as regulatory complexity and client expectations mount, firms that systematically invest in building advisory capabilities are outperforming their peers by significant margins 鈥� and the performance gap is widening.

From compliance shop to strategic advisor

For tax firm leaders, this transformation represents both validation and opportunity. The numbers tell a compelling story, especially for firms that are proactively leading the strategic elevation of their advisory capabilities. Among surveyed respondents from firms experiencing revenue growth, 88% report that advisory revenue is growing faster than compliance revenue and that advisory services now represent an average of 31% of total firm revenue.

Not surprisingly, many forward-thinking firms are backing this shift with concrete plans. Nearly 9-in-10 respondents say their firms are planning to expand their advisory services within the next year.

The engagement advantage

What’s driving this transformation? According to the report, the quality and frequency of client relationships have fundamentally recast what’s possible in tax advisory services. Firms that meet with clients quarterly or more frequently see dramatically different outcomes than those meeting clients just once or twice a year.

Tax professionals from firms with quarterly touchpoints rated their own satisfaction significantly higher across every dimension measured, such as knowledge of the client’s business, understanding the client’s industry sector, the overall strength of the client relationship, and the range of services the client uses. Even more compelling, almost 90% of respondents from firms with more frequent client engagement report that advisory revenue growth is outpacing compliance growth compared to just 65% of respondents from firms with less frequent client contact.

As the report underscores: This message is unmistakable 鈥� relationship depth directly drives revenue growth. Firms that use quarterly or more touchpoints with clients are more successfully converting compliance-only relationships into comprehensive advisory partnerships at substantially higher rates than their less-engaged competitors.

The challenging landscape

Despite the opportunities that abound in advisory services, many firms face real obstacles in expansion, the report shows. More than half (52%) of respondents cite staff skills gaps among their colleagues as their biggest challenge, followed closely by client resistance to paying for advice (47%).

These challenges create a reinforcement loop that can trap firms in their current state: Staff lack advisory skills, so they focus on compliance work, leaving no time to develop advisory capabilities or engage clients proactively. Then, clients don’t see the value of advisory services because they haven’t experienced them, and the cycle continues.

Breaking this loop requires intentional strategy and systematic execution 鈥� which is exactly what leading firms are doing differently, the report shows.

How strategic priorities are reshaping the profession

The ripple effects from this advisory transformation have dramatically reshaped strategic priorities for tax firms beyond routine concerns about service expansion. These new priorities represent fundamental shifts in how firm leadership view the purpose of their firm, its client relationships, and competitive positioning.

Interestingly, while revenue objectives dominate the top priorities, 13% of firm leaders cite developing more intellectually stimulating work for their teams as a key objective, the report shows. This speaks to a deeper strategic consideration 鈥� that advisory work itself offers the kind of challenging, engaging work that attracts and retains top talent in an increasingly competitive labor market.

Today, the opportunity is here for tax firms to capitalize on this momentum and operationalize their advisory services offerings through formalized processes, systematic client engagement, technology leverage, and value-based pricing that creates enduring competitive advantages.

As the report shows, tax advisory today is moving beyond simply offering occasional consulting services alongside compliance work. And with the strategic elevation of tax advisory services already underway, it鈥檚 those firms that move quickly enough to capture the opportunity that will flourish.

Key findings:

• • • • Strategic blind spots remain 鈥� Despite widespread awareness, many tax firms have yet to fully assess the operational or financial impact of the reform, highlighting the need for more proactive planning as changes approach.

      • Technology investment leads the way 鈥� Firms are prioritizing technology and now are beginning to complement these efforts with increased attention to staff training and client support, aiming for a more balanced and complete transition.

      • Client guidance is gaining momentum 鈥� While clients will be among the most affected, professionals are recognizing the urgency of providing clearer communication and tailored support to help clients navigate the reform more confidently.

Brazil鈥檚 tax, audit & accounting sector is on the verge of a historic transformation. The country鈥檚 new tax reform, approved by the National Congress, will gradually unify several existing taxes into a dual value-added tax (VAT) system. The reform aims to simplify compliance, promote transparency, and help citizens better understand how public resources are allocated.

Brazil Tax Reform for Tax Firm Professionals 2025

So how prepared are Brazil鈥檚 tax & accounting professionals for this upcoming shift? A new report from the 成人VR视频 Institute reveals a gap between awareness and action. While most professionals understand the reform and its implications, only a minority have moved into active preparation. Only a small group of firms have established internal teams or concrete plans; however, many others are now beginning to shift from passive monitoring to more decisive steps.

Definitions: Incipient: I am aware of the Tax Reform, but I am not keeping up with the changes. Beginner: I am following updates through the press and reports to evaluate information that fits the firm鈥檚 and customers鈥� profile. Preparatory: I have an internal working group and/or a developing plan. Advanced: I have allocated resources and a transition project in progress. Leader: I have the structure prepared for the transition and I am working with my team and external providers to anticipate our adaptation.

The reform is expected to impact core areas of tax, audit & accounting work 鈥� including tax calculation, pricing strategies, and advisory services. Professionals widely acknowledge these areas will be disrupted and are starting to take steps to assess and prepare for the changes. Technology investment is accelerating, with many firms upgrading systems and digital infrastructure to meet new requirements. At the same time, there is growing recognition that staff training and client education must advance in parallel to ensure a successful transition.

Many professionals have expressed a need for more resources and structured plans to help them guide clients through the reform, especially as they face changes in tax burdens, pricing structures, and compliance requirements. Encouragingly, firms are beginning to respond 鈥� developing communication strategies and training programs to better support both their teams and their clients.

One major area still evolving is the financial planning around the reform. Despite the potential for significant operational changes, most organizations have yet to estimate the cost of adaptation. As new requirements take effect, understanding and preparing for these costs will be essential to avoiding unexpected disruptions.

Opinions on the reform鈥檚 complexity remain divided. Some professionals expect simplification, while others anticipate greater difficulty in tax and accounting practices. This uncertainty only reinforces the importance of ongoing monitoring and the development of flexible strategies.

While technology remains a central focus, the sector is now beginning to align its efforts 鈥� recognizing that human capabilities and client engagement are equally essential. The transition is no longer just about systems and infrastructure, but also about empowering their professionals and building trust. Firms are taking steps to ensure that their teams are prepared and their clients are supported, thereby laying the groundwork for a more complete and resilient transformation.

Key takeaways:

• • • Tax requirements have become more complex 鈥� The 2025 R&D credit reporting requirements have become significantly more complicated, demanding detailed business component and expense breakdowns.

    • AI may offer solutions 鈥� AI-driven platforms that are aligned with new IRS expectations can offer practical solutions to strengthen substantiation, simplify technical narratives, and ease the documentation burden.

    • Pre-planning and preparation are key 鈥� Proactive audit preparation, strategic communication, and awareness of recent IRS procedural changes are critical for successful resolution of R&D examinations.

This year marks a milestone for the corporate tax community as the tax code鈥檚 Section G Research & Development credit reporting enters the mandatory phase for returns exceeding $1.5 million in qualified research expenses or $15 million in gross receipts. Formerly, taxpayers faced little more than two simple fields on 鈥� now, however, filers must provide granular detail at the business component level.

These new requirements include breaking out employee expenses (direct, supervisory, and support), and separating additional qualified categories like supplies, computer leasing, and contract research for every component. The new requirements mirror global trends seen in countries such as Germany and France, where R&D credit documentation has historically been much more burdensome.

How documentation has changed

Historically in the United States, many aspects of R&D substantiation were included in the study and not presented on the tax form itself. In June 2024, the IRS released a revised draft of Form 6765 鈥� and provided 鈥� that included the updated stance demanding transparency. Wherein every business component, its relation to controlled groups, the type of component, and the wage/expense breakdown must be represented on the tax return. The implication is clear: Taxpayers must bolster their documentation, ensuring contemporaneous evidence that is not solely prepared for tax purposes.

Compared to many foreign jurisdictions, especially those in Europe, the US still offers relatively less burdensome requirements; however, this directional shift is unmistakable. Complex, technical project narratives and granular wage allocation are increasingly expected by US tax authorities. The IRS indicates that it presumed all filers already performed this granular breakdown. Now, the reporting burden moves from optional best practice to taxable necessity.

Shifting audit terrain

In a , presented by 成人VR视频 and Tax Executives Institute, panelists also discussed audit shifts. Indeed, 2025 brings procedural shifts within the IRS鈥檚 audit playbook. Notably, the elimination of the agreement of facts process at the conclusion of Large Business & International audits in early 2026 removes a formal avenue that filers can use to respond to the IRS鈥檚 versions of events before the Notice of Proposed Adjustment is issued. This heightens the importance of detailed, factual Information Document Request (IDR) responses throughout the entire audit, ensuring a well-documented appeals record if needed.

Additionally, tools like the Accelerated Issue Resolution (AIR) and Fast Track Settlement programs are expanding. These initiatives streamline multi-year disputes and improve the odds of reaching taxpayer-favorable outcomes, particularly as IRS management and appeals officers seek more efficient, resource-aware resolutions. Recent experience shows a trend: Fast Track settlements are securing more positive outcomes for taxpayers 鈥� sometimes even when the parties are far apart on the numbers.

State audits add their own complexity, especially because many states don’t recognize federal Accounting Standard Codification 730 directives. Tax departments must proactively develop full substantiation for state reviews, rather than relying solely on federal documentation standards or shortcuts. Partnering with audit-experienced professionals, especially those with IRS backgrounds, can further improves audit results.

Turning burden into benefit

The new mandates from Section G are not a signal to retreat from claiming the credit. Despite elevated standards, the credit remains a vital incentive for businesses. Rather than being deterred, corporate tax departments can use this to bolster their requests for more technology investment, including AI-driven tools and solutions.

The arrival of advanced generative AI (GenAI) models makes R&D credit substantiation faster and more precise than ever before. These tools have capabilities that include:

• • • Ingesting and organizing vast quantities of technical and operational documentation into IRS-compliant formats
    • Translating technical jargon into tax-speak, ensuring that every business component gets a concise, accurate, and compliant technical narrative
    • Assisting in quantifying R&D time at the individual level, mapping granular time and activities to precise expense categories
    • Generating contemporaneous documentation referenced directly to underlying evidence or regulatory authority for bulletproof

Corporate tax professionals also can take tedious and manual tasks 鈥斅� such as interviewing engineers, mapping activities, and defending allocations 鈥� and now use AI to manage this work at scale. Real-time views of qualified R&D activity, lessened reliance on labor-intensive surveys, and immediate provisioning all contribute to faster, more rigorous studies, bigger credits, easier audits, and happier R&D teams.

Preparing for 2025 returns and beyond

There are several actions that corporate tax teams can take now to prepare for 2025 returns, including:

• • • Embrace AI and contemporary documentation workflows to meet new substantiation and reporting burdens
    • Build IDR responses, audit narratives, and documentation as if they will be reviewed in appeals or in court 鈥� precision and completeness are paramount
    • Cultivate constructive auditor relationships, whether federal or state, with a mindset focused on problem-solving rather than confrontation
    • Consider Fast Track and AIR strategies for accelerated and possibly more favorable dispute resolution in multi-year credit audits
    • Continually monitor IRS and state developments, regulatory guidance, and prominent cases as precedents shift norms and expectations.

R&D credit compliance has evolved from simple reporting to sophisticated, data-driven substantiation. With increased detail required for every dollar claimed, corporate tax departments must adapt quickly.

They now need to be leveraging advanced technology, have subject matter expertise, and create more transparent auditor relationships. Having AI-powered tools is a necessity to making more accurate credits and smoother audits a tangible reality. The bottom line is that R&D credits are valuable and corporate tax department teams will now need to invest time and expertise to get them right.

Key findings:

• • State-level changes 鈥� States are responding to the impact of OBBBA on state-level taxation.

  • Budget shortfalls may result 鈥� Several states are already projecting reduced revenue collections because of the OBBBA.

  • Multi-state business impacts 鈥� Businesses with multi-state operations should re-evaluate where their operations are located for tax purposes.

The One Big Beautiful Bill Act (OBBBA) ushered in sweeping federal tax changes including provisions aimed at stimulating domestic business investment, particularly in manufacturing and research & development. While many businesses welcome the enhanced federal deductions, the changes are also significantly shifting the landscape for taxation at the state and local levels.

The impacts of the OBBBA are playing out differently across states, depending on each state鈥檚 own tax rules. In addition, the Act is likely to have fiscal ripple effects for states, including new budget challenges. How states respond to these combined impacts promises to dramatically reshape the tax environment, particularly for businesses operating across multiple jurisdictions.

These are among the considerations that seem to be keeping clients up at night 鈥� despite the federal tax benefits of the Act, many business owners and tax professionals are nervous about what it鈥檚 going to be mean at the state and local levels.

Impact on state-level tax policies

For businesses that operate across multiple states, the state and local tax landscape is suddenly more dynamic and much less predictable. States generally start their income tax calculations based upon federal taxable income, but they then modify those numbers based on their own rules and legislative priorities. That means federal changes, such as bonus depreciation or research expensing, are often partially or fully clawed back at the state level. So key provisions of the OBBBA, particularly those involving deductions and R&D expenses, will impact specific businesses differently depending on a state鈥檚 existing tax rules and policies.

For example, the OBBBA allows immediate 100% expensing for federal purposes for fixed assets placed in service after January 19, 2025. However, many states already decouple their assessments from federal bonus depreciation. Other states adjust the percentage or disallow the bonus entirely, forcing an addback and requiring businesses to instead use standard federal depreciation schedules. In fact, OBBBA threatens to widen these differences for deductions.

The impacts of the OBBBA are playing out differently across states, depending on each state鈥檚 own tax rules.

Similarly, the OBBBA enhances the ability of businesses to expense qualifying domestic R&D costs. Historically, only a few states followed the federal shift from expensing to capitalization under prior law. Some states, such as Indiana, may now conceivably permit a double deduction for these expenses under concurrent federal and state codes. Meanwhile, other states will likely reassess or restrict the treatment of these deductions because of concerns over the potential negative impact on state revenues.

Michigan and Rhode Island, for example, recently enacted legislation decoupling from the OBBBA provision that allows for the immediate deduction of domestic research and development expenses, resulting in the continued requirement to capitalize such amounts for state purposes.

State budget concerns

Meanwhile, concerns about the effect of the Act on state revenues could result in far more significant impacts.

One of the most immediate consequences of the OBBBA has been already observed in several states: Illinois, Maryland, Nebraska, and Oregon are among the states that have publicly acknowledged that major federal funding cuts in programs like Medicare, Medicaid, SNAP food assistance, and broader social services are likely to trigger budget shortfalls. And Colorado recently announced a projected $1 billion shortfall, prompting tax increases and a November 2026 referendum to raise income tax rates on certain high-income levels.

While clearly, nobody has a crystal ball, the OBBBA is already putting a lot of strain on state budgets and more states will likely follow in Colorado鈥檚 footsteps.聽 Indeed, at a Massachusetts Department of Revenue roundtable held September 30, Commissioner Geoffrey E. Snyder declared that the OBBBA is projected to reduce the state鈥檚 revenue collections by almost $700 million in their 2026 fiscal year.

Impact on businesses

For businesses, navigating through all these changes complicates everything from daily operations to long-term strategy planning 鈥� and the stakes are considerable.

New tax increases or other changes in state tax rules could change asset deployment strategies, shift business expansion plans, and even encourage relocation to more favorable jurisdictions. Robust proactive tax planning is now a competitive necessity rather than a defensive maneuver.

To get on top of this, tax professionals should look into adopting more customized, multi-state mindsets for their clients. It鈥檚 essential that tax professionals fully grasp the substance and trajectory of each material state, or those states in which their clients鈥� businesses have significant business activity. Given that most states currently apportion taxable income primarily based on revenue, rather than physical presence, the rules governing each material state should be monitored closely in addition to the state in which the client is headquartered.

To get on top of this, tax professionals should look into adopting more customized, multi-state mindsets for their clients.

Further complicating matters is that the ripple effects from state responses will vary considerably in terms of timing. Some state legislatures only meet biennially, while some states may call special sessions to address urgent revenue needs or adjust their rules to conform with federal law. States also may enact rapid changes in response to headline-making budget projections 鈥� often with little warning.

Tax professionals need to stay proactive and vigilant, and most importantly, keep their finger on the pulse of state tax policies to best keep their clients informed. Some key steps for tax professionals include:

• • • Conduct a 鈥渕aterial state鈥� audit 鈥� Proactively identify and monitor those states in which clients have meaningful revenue, as those locations will now drive new tax risks and opportunities.
    • Stay informed on legislative developments 鈥� Closely track statements from state governments, economic development departments, and relevant tax and economic authorities on budget forecasts and discussion of anticipated responses.
    • Educate and advise clients with flexibility and understanding 鈥� Provide clients with regular updates on state-level changes and counsel them to build flexibility into their business forecasts and strategies, especially around capital expenditures and R&D investments.

While the OBBBA is ultimately a federal catalyst 鈥� the state and local reverberations of the Act are just beginning to be felt. For tax professionals, this is a moment to lead by educating clients, anticipating legislative shifts, and building resilient tax strategies across jurisdictions. State and local responses to the OBBBA will be diverse and are only beginning to unfold. Steady guidance from tax professionals can make the difference between whether their clients thrive or flounder amid all these changes.
