In April 2025, the IRS and the Department of Homeland Security (DHS) formalized a Memorandum of Understanding (MOU) enabling Immigration and Customs Enforcement (ICE) to create a system of information sharing between the agencies. Under the MOU, the IRS can share tax return information for non-tax criminal investigation purposes. More specifically, the MOU permits ICE to request sensitive tax information from the IRS for purposes of pursuing immigration related cases and deportations. Given the Trump administration’s focus on undocumented workers, the implications of the MOU likely will go even further as sharing this information will result in tax enforcement against employers of deported individuals.

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (the “Act”), after it was passed by Congress on July 3, 2025. Notably, the Act made significant and welcome changes from the perspective of startup company stockholders and venture capital investors to the qualified small business stock (“QSBS”) rules set forth in Internal Revenue Code (“Code”) Section 1202. In a nutshell, the changes modernize (by adjusting for inflation) and expand the already favorable tax treatment for QSBS under Code Section 1202. The Act also permanently reinstates elective expensing for qualifying domestic research and experimental expenditures that will likely help more startups in research and capital intensive sectors qualify for favorable QSBS treatment.

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (the OBBBA) which amended a number of Internal Revenue Code provisions related to employee benefits and compensation. Although not an exhaustive list, below are the provisions we expect will have the greatest impact on compensation and benefits for mid- and larger sized employers.

On July 4th, President Trump signed into law the One Big Beautiful Bill Act (the “Act”), which included a phaseout of incentives for solar and wind generation projects. Projects must either begin construction within one year or be placed in service by 2027 to qualify for the Section 45Y Clean Electricity Production Tax Credit or the Section 48E Clean Electricity Investment Tax Credit. The House’s version of the legislation required a more accelerated phaseout than the Act and only allowed projects that began construction within 60 days of enactment of the bill to be eligible for the tax credits.  In discussions last week with House conservatives who favored the faster phaseout of solar and wind tax credits, which was not adopted in the Act, President Trump promised strict enforcement of the rules, including the beginning of construction requirements, for solar and wind projects to qualify for energy tax credits.

On May 20, 2025, former Missouri congressman, Billy Long, appeared before the Senate Finance Committee for his confirmation hearing as President Donald Trump’s nominee for IRS Commissioner.  Senators questioned Long about his role in promoting questionable tax credits, including Employee Retention Tax Credits (“ERTC”) after leaving the House of Representatives in 2023.  Long also disclosed receiving financial compensation from these entities for his work promoting ERTC.  Given Long’s support for ERTC, there is speculation that the IRS could ease enforcement activity directed towards these credits.

On May 13, the House Ways and Means Committee passed “The One, Big Beautiful Bill.” This bill includes several provisions that, if enacted, will be important to businesses claiming research and development incentives:

In the wake of the Trump Administration’s recent scrutiny of various nonprofit organizations, including Harvard University, and threats to revoke organizations’ tax-exempt status, nonprofit organizations should take proactive steps in the event of an IRS audit that may target their federal tax-exempt status. Proactive planning and preparation measures are essential to being well-equipped to deal with potential IRS inquiries or an audit. The faster and more efficiently an IRS inquiry can be concluded, the better likelihood of avoiding a full audit or worse, revocation of status. An organization may be particularly vulnerable where there has been any level of political involvement that could be viewed as controversial, but also involvement with activities and efforts focused on renewable energy and diversity, equity & inclusion (“DEI”) may now cause additional scrutiny of an organization’s tax-exempt status. Common potential foot-faults that can bring an organization into the crosshairs (and which are oftentimes not fully considered in light of potential risk of revocation of tax-exempt status) include negotiating typical agreements, including commercial contracting and similar arrangements, where contractual provisions may call for representations and commitments from a non-profit around its DEI efforts or similar efforts. Extra care should be taken to review such instances and other potential activities that may increase the organization’s risk of IRS audit.

In a significant decision for generic drug manufacturers, the Federal Circuit recently affirmed that litigation expenses incurred in defending Hatch-Waxman patent lawsuits are deductible as ordinary and necessary business expenses under the Internal Revenue Code (IRC). The ruling in Actavis Laboratories FL, Inc. v. United States, No. 23-1320 (Fed. Cir. Mar. 21, 2025), resolves a key tax dispute, allowing tax deductions for these expenses in the year they are incurred rather than capitalizing them over time. This outcome provides clarity and potential tax benefits for qualifying businesses navigating the interplay of patent litigation and FDA drug approvals.

On February 18, President Trump issued an Executive Order titled “Ensuring Accountability for All Agencies” that directs independent agencies (as well as Cabinet Departments and their sub-agencies) to route all “proposed and final significant regulatory” and budgetary actions through the White House and the Office of Management and Budget. If implemented to its full extent, this action will significantly strengthen the authority of the White House by weakening the political autonomy of these independent agencies. As an assertion of the President’s inherent powers under Article II of the U.S. Constitution, it also stands to weaken congressional influence over these independent agencies, both through the appropriations and confirmation processes.

Companies with employees in the Southern California area have several tax-advantageous alternatives when providing employees with disaster relief.  This alert outlines the more common relief programs available under IRS guidance.

Since its passage in 2022, the Inflation Reduction Act’s renewable energy tax credits have been in the crosshairs of Congressional Republicans. With many of the Tax Cuts and Jobs Act provisions expiring at the end of 2025, and a full plate of Trump and Congressional Republican Campaign promises for tax cuts in play, the Republicans have pointed to repeal of the IRA as a source of funding to pay for other tax breaks.

On October 24, 2024, Crowell & Moring LLP hosted its 38th Annual Managing Tax Audits and Appeals Seminar. The seminar featured several prominent IRS speakers and lively discussion among clients, including conversations about the following hot topics:

With a new President entering office in January 2025 and many key Tax Cuts and Jobs Act provisions expiring (TCJA) on December 31, 2025, both sides of the aisle are teeing up a massive effort to renew, extend, roll back, or make permanent various provisions of former President Trump’s signature tax bill and President Biden’s signature climate bill. Just about every business sector will be impacted by how Congress and the new administration approach TCJA and other tax issues. Here is a sneak peek into the top five issues our tax and policy experts expect to come up in that debate based on the campaign positions of Vice President Harris and former President Trump.

On Friday, June 28, 2024, the U.S. Supreme Court overruled Chevron U.S.A. v. Natural Resources Defense Council (“Chevron”)[1] in Loper Bright Enterprises v. Raimondo (No. 22-451) and Relentless v. Dep’t of Commerce (No. 22–1219)[2] (the two cases collectively referred to as “Loper Bright”), bringing an official end to the decades-old and eponymously named “Chevron deference” doctrine. Not content to stop there, the Court returned fresh to work Monday, July 1, to, in Corner Post, Inc. v. Board of Governors of the Federal Reserve System (No. 22-451)[3] (“Corner Post”), effectively extend the limitations period to challenge final agency actions under the Administrative Procedure Act (“APA”).

On April 25, 2024, the Department of Labor (“DOL”) published a final rule (the “Final Rule”) regarding when providing investment advice results in the advisor becoming a fiduciary under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and the Internal Revenue Code of 1986, as amended (the “Code”).  Under this guidance, an entity is a fiduciary if the provider of that advice to an ERISA plan or Individual Retirement Account:

The Treasury and IRS published their final rules on transferability for clean energy tax credits on April 30, 2024. The final rules include very few changes from the proposed regulations and rejected many of the suggestions offered by commenters during the public hearing.

Tax partner and co-chair Starling Marshall and tax partner Carina Federico discuss where they predict tax disputes may arise with the IRS related to the IRA clean energy provisions. 

Last week, the IRS announced plans to begin a campaign to audit personal use of business aircraft. The audits will focus on whether large corporations, partnerships and high-and ultra-high net worth aircraft owners have properly reported their business and personal aircraft usage for tax purposes, with a particular focus on ensuring that owners are only taking deductions to which they are entitled. Given the value of an aircraft, the amount of a deduction for aircraft related expenditures on a given taxpayer’s return can be in the tens of millions of dollars, and with more than 10,000 corporate jets operating in the U.S., IRS Commissioner Daniel Werfel recognized that much is at stake with this campaign.  The audit campaign is expected to focus initially on multinational and domestic corporations and complex partnerships but is expected to expand from there.
