As 2025 unfolds, U.S. tax policy is poised for significant shifts, particularly with a new Republican administration under President Donald Trump. The year ahead will likely see a range of tax reforms, largely driven by the GOP’s objectives and campaign promises. In this article, we’ll explore the major tax policy trends, legislative developments, and administration changes that may shape U.S. tax law in 2025.
The Impact of Supreme Court Decisions
2024 also saw two major Supreme Court decisions with significant tax implications. In the Moore case, the Court ruled narrowly on the issue of wealth taxation, leaving open the possibility of revisiting the question in the future. While wealth tax proposals had gained some traction among Democrats, the Court’s decision, combined with the political climate, suggests that such proposals are unlikely to gain much momentum under the new administration.
The Loper Bright decision, which questioned the deference given to government regulations, could have far-reaching effects on tax policy. The ruling makes it more difficult for agencies like the IRS to issue regulations without clear legislative guidance, potentially leading to more legal challenges to IRS regulations and shifting the balance of power between lawmakers and regulatory agencies.
2025: A New Republican Agenda
With a Republican administration taking office in 2025, tax policy is expected to shift dramatically. President Trump, along with a Republican-controlled Senate and House, will likely push for several key changes to tax law.
One of the primary objectives will be to extend provisions of the 2017 Tax Cuts and Jobs Act (TCJA) that are set to expire. This includes individual tax cuts, corporate rate reductions and changes to the state and local tax (SALT) deduction cap. The extension of other expiring provisions involving lifetime gift and estate tax exemptions, AMT, child tax credits, and the mortgage interest deduction may also be on the table. Additionally, the GOP is expected to explore new tax cuts, with some lawmakers proposing measures like eliminating taxes on tips, which was promoted during Trump’s election campaign.
On the corporate side, there may be discussions about lowering the effective tax rate through credits and incentives rather than direct reductions to the statutory corporate tax rate. There also could be movement on tax expensing for research and development, as well as other measures to incentivize business investment.
Potential Revenue-Raising Measures
Despite the tax cuts expected to dominate the agenda, there may be some revenue-raising measures included in the GOP’s tax proposals. The focus on reducing deficits could lead to efforts to cut some of the green credits in the Inflation Reduction Act, although these cuts are unlikely to raise significant revenue. There also may be attempts to tighten international tax rules from the TCJA to generate more revenue.
President Trump has also proposed replacing individual income taxes with increases in tariffs, implementing a universal 20 percent tariff across the board, and implementing an additional 50 percent tariff on imports from China.
IRS Funding and Administration Changes
Under the new administration, the IRS is expected to face significant cuts, particularly in its enforcement budget. The $80 billion allocated to the agency in recent years, which was intended to improve taxpayer services and combat tax evasion, is likely to be rolled back. Republicans have expressed strong opposition to the IRS’ expanded powers and are expected to push for a reallocation of those funds toward customer service rather than enforcement.
Additionally, the new administration may replace current IRS Commissioner Daniel Werfel, who was appointed during the Biden administration. Trump could nominate a new commissioner, and if this happens, it could spark further debates over the direction of the IRS in the coming years.
Conclusion
2025 promises to be a dynamic year for U.S. tax policy, with significant changes expected under the new administration. Key issues to watch include the fate of the TCJA’s expiring provisions, potential new tax cuts, and ongoing debates over IRS funding and regulations. As the administration works to implement its agenda, there will likely be contentious discussions and compromises on Capitol Hill, setting the stage for a new era of tax policy for the United States.
