As the expiration of key Tax Cuts and Jobs Act provisions looms, tax professionals are preparing for what could be another period of upheaval.

In 2017, when the TCJA was first enacted, tax departments struggled to keep pace with new regulations and guidance. According to our recent Bloomberg Tax survey of 434 tax professionals, 92% of tax professionals working in tax at the time reported that the TCJA’s implementation was moderately to highly disruptive, and 60% said it took a year or more to fully implement the changes. 

The coming year could bring more of the same. Eight in 10 respondents are moderately or very concerned about the potential impact of these changes. Yet many rely on outdated, manual processes that make adjusting quickly to major legislative changes difficult.

With the benefit of hindsight, tax professionals have a unique opportunity to apply the lessons of 2017 and invest in automation now to avoid repeating the same costly mistakes.

Manual processes still dominate tax departments

One of the most striking findings from our survey is that many tax professionals continue to rely on manual workflows despite the increasing complexity of tax compliance. Seventy-six percent of respondents said they still use Excel for tax calculations, and 63% manually gather data from enterprise risk management and general ledger systems to perform tax calculations.

These outdated processes create inefficiencies and make it harder for tax teams to respond quickly to legislative changes.

In its time, the TCJA was the most sweeping tax code overhaul in decades. It required tax departments to significantly modify or even replace their workpapers to reflect the changes. 

While 62% of survey respondents believe they can update their existing workpapers without major difficulty, one in four anticipate significant challenges, and 10% will need to create entirely new workpapers.

This manual burden could put firms at a disadvantage when deadlines are tight and compliance requirements shift rapidly.

Scenario modeling is challenging yet critical

When big changes are on the horizon, running multiple tax planning scenarios helps organizations make decisions and manage risk. Automated tax solutions streamline this process by allowing tax teams to evaluate different legislative outcomes and come up with strategies to address them.

Firms that lack automation in their tax workflows may have a tough time keeping up with the pace of change — especially if Congress waits until the eleventh hour to pass legislation, as was the case in 2017.

Eighty-eight percent of respondents reported it is moderately or very difficult to conduct scenario modeling for TCJA changes, and only half have started the process. One respondent noted, “We need as much lead time as possible to make changes to our models, and significant changes take even more time to incorporate. Running multiple scenarios is a very manual and difficult process.”

Quantifying the cost of inaction

Failing to invest in automation before a substantial tax law change can be a costly mistake.

Among respondents, 71% who experienced the enactment of TCJA in 2017 reported wishing they had invested earlier in tax technology to better manage the complexity of compliance updates. Manual processes not only slow response times but also drive costs, as nearly 40% of respondents anticipate a $100,000 or higher increase in consulting budgets if significant TCJA-related changes occur. 

By leveraging tax automation tools and centralized tax-focused software, firms can optimize how they engage with external consultants. Automation allows tax departments to take ownership of routine processes, such as calculations and compliance adjustments, reducing reliance on consultants for these tasks. Instead, consultants can be utilized more effectively on high-impact projects that drive strategic value, such as tax planning, risk management or navigating complex regulatory changes. This shift enables firms to streamline compliance while ensuring external expertise is directed toward creating lasting organizational benefits.

Preparation now means greater confidence going into 2026

The data is clear: firms investing in automation today will be better positioned to handle the upcoming tax changes confidently. Here’s how to get ahead:

• Integrate tax technology. Replace manual calculations in Excel with automated tax workpapers that integrate with source data and automate data gathering and calculation processes.
• Adopt scenario modeling tools. Invest in software that allows for real-time legislative modeling so you can analyze multiple potential outcomes before changes take effect.
• Reduce reliance on external consultants. Implement in-house tax software to keep control over your data, reduce consulting budgets and respond quickly to regulatory shifts.

With less than a year until TCJA provisions are set to expire, the time to act is now. Taking proactive steps to automate and modernize your workflows will put you in a far stronger position than companies that wait until the last minute. 

Major tax law changes can be disruptive, but with the right technology, you don’t have to relive the turmoil of 2017. Embrace tax-focused automation to remain agile, efficient and ready to navigate whatever changes come next.

The Securities and Exchange Commission voted to end its legal defense of the climate-related disclosure rule it approved last year under the Biden administration.

The climate disclosure rule was facing numerous lawsuits from business groups and a temporary stay imposed by a court, the SEC had already paused it last April after narrowly approving a watered-down rule last March. The former SEC chairman, Gary Gensler, who had pushed for the rule, stepped down in January and acting chairman, Mark Uyeda, who had voted against the rule, announced in February that he was directing the SEC staff to ask a federal appeals court not to schedule the case for argument. He cited a recent presidential memorandum from the Trump administration imposing a regulatory freeze, and he effectively paused the litigation. The vote on Thursday effectively suspends the rule.

“The goal of today’s Commission action and notification to the court is to cease the Commission’s involvement in the defense of the costly and unnecessarily intrusive climate change disclosure rules,” Uyeda said in a statement Thursday.

The SEC noted that states and private parties have challenged the rules, and the litigation was consolidated in the Eighth Circuit Court of Appals. SEC staff sent a letter to the court stating that the Commission was withdrawing its defense of the rules and that Commission counsel are no longer authorized to advance the arguments in the brief the Commission had filed. The letter stated that the SEC yields any oral argument time back to the court.

One of the SEC commissioners blasted the move and pointed to the arduous, years-long process of crafting the climate rule. “By way of politics, the current Commission would like to dismantle that rule. And they would like to do so unlawfully,” said SEC commissioner Caroline Crenshaw in a statement Thursday. “The Administrative Procedure Act governs the process by which we make rules. The APA prescribes a careful, considered framework that applies both to the promulgation of new rules and the rescission of existing ones. There are no backdoors or shortcuts. But that is exactly what the Commission attempts today. By its letter, we are apparently letting the Climate-Related Disclosures Rule stand but are withdrawing from its defense in court. This leaves other parties, including the court, in a strange and perhaps untenable situation. In effect, the majority of the Commission is crossing their fingers and rooting for the demise of this rule, while they eat popcorn on the sidelines.”

Environmental groups were critical of the SEC’s vote. “Climate change is a growing financial risk, and ending the SEC’s defense of its own climate disclosure rule is a dangerous retreat from investor protection,” said Ben Cushing, sustainable finance campaign director at the Sierra Club, in a statement. “Letting companies hide climate risks doesn’t make those risks any less real — it just makes it harder for investors to manage them and protect their long-term savings. The SEC is leaving investors in the dark at exactly the moment transparency and action is most needed.”

“The SEC was established to protect investors, and for more than 20 years, investors have clearly and overwhelmingly stated that they need more clear, consistent, and decision-useful information on companies’ exposure to climate-related financial risks,” said Steven M. Rothstein, Ceres’s managing director for the Ceres Accelerator for Sustainable Capital Markets, in a statement. “The ongoing acceleration of physical climate impacts, including the tragic fires in Los Angeles, has underscored the importance of transparency on these risks. Investors have clearly indicated they require better disclosure, with $50 trillion in assets under management broadly supportive of the rule adopted in March 2024. This is clearly a step backward in helping investors and other market participants have the information they need to manage climate-related financial risks.”  

Aprio has struck a deal to acquire RSM US LLP’s Professional Services+ practice in the U.S. and Canada. The PS+ practice serves nearly 80 firms across the U.S. and Canada and offers services related to strategy and leadership, talent development, business processes and operations, and access to group buying solutions. 

The deal is expected to close April 30, subject to closing conditions, and the PS+ practice will operate as part of Aprio effective May 1. The current leader of RSM’s PS+ practice, Dean Sengstock, will continue to lead it and join Aprio as a partner along with four other partners and over 30 team members. 

“In joining Aprio, we have a unique opportunity to carry forward our vision and customized approach for serving clients the way they want to be served,” Sengstock said in a statement Friday. “While we are joining a new firm, our team, the services we provide, and our commitment to exceptional client-centric service, remains the same.” 

Financial terms of the deal were not disclosed. RSM US, based in Chicago, ranked No. 5 on Accounting Today‘s 2025 list of the Top 100 Firms, with over $4 billion in annual revenue i fiscal year 2024, while Aprio, based in Atlanta, ranked No. 24 and earned over $485.34 million in annual revenue in FY 2024.

RSM had more than 17,000 partners, principals and employees in FY 2024. Of this total, 1,183 are partners and principals. Aprio has 204 partners. RSM’s Professional Services+ Practice expects to bring five partners and 30 team members to Aprio. 

“It is an honor to welcome the PS+ practice, clients and team to Aprio. RSM has provided an exceptional platform for the past four decades for the PS+ practice and we are committed to establishing a strong foundation to grow the practice at Aprio,” said Aprio CEO Richard Kopelman in a statement Friday. “With the addition of the PS+ practice, Aprio will include a robust community of complementary firms with unique opportunities for collaboration and growth as we invest in the future.” 

Aprio received a private equity investment last July from Charlesbank Capital Partners. Earlier this month, Aprio acquired JMS Advisory Group in Atlanta. Aprio has completed over 20 mergers and acquisitions since 2017.

“We believe this transaction enhances the PS+ team’s ability to continue supporting their clients, while enabling RSM to focus on our core assurance, tax and consulting service offerings for the middle market,” said RSM US LLP managing partner and CEO Brian Becker in a statement. “We are grateful to the PS+ team for their many contributions to RSM over the last 40 years.”  

Last October, RSM US and RSM UK announced plans to combine by the end of this year.
