“There may be liberty and justice for all, but there are tax breaks only for some.” Martin A. Sullivan. In the pursuit of these breaks, taxpayers frequently engage professionals – lawyers, accountants, appraisers, actuaries, and others – to identify opportunities to minimize their tax burden. But when does tax avoidance cross the line? The IRS has prioritized its examinations of and investigations into perceived abusive tax shelters and transactions and, in doing so, is targeting the professionals involved through preparer and promoter investigations, disciplinary proceedings before the Office of Professional Responsibility, and criminal investigations. This panel addresses the potential exposure for professionals assisting taxpayers with tax advantaged transactions, and current enforcement actions.

DISABILITY IN THE LEGAL PROFESSION – ARE YOU OVERLOOKING TALENT AND MISSING OPPORTUNITIES? – Moderator: Nina E.

The legal profession can be extremely fast-paced and hypercompetitive, creating pressure among legal professionals to downplay any disability to minimize the risk of explicit or implicit bias, stigma, or simply reduced work assignments. While law firms are striving to accelerate and enhance diversity, equity, inclusion, and accessibility (“DEIA”) efforts for females, minorities, and LGBTQIA+ professionals, fewer firms mention or have implemented policies and practices to address disabilities in their diversity efforts. Only 1.4% of attorneys report having disabilities, but this number is three times higher than in 2019 and organizations are recognizing the need to expand their disability DEIA efforts. This panel addresses the need for “leadership by example” in the legal profession, including education and training for those with disabilities, the provision of necessary resources, and efforts to foster inclusion.

The global marketplace and increased individual mobility has created additional scenarios where US taxpayers are sending payments outside the United States and thereby making them subject to US withholding and reporting requirements. IRS LB&I has a compliance campaign to examine taxpayers who make such payments but fail to meet their compliance obligations. This panel identifies the subset of taxpayers (withholding agents) who are responsible for withholding US tax on payments to foreign payees, explains the surprising ways withholding agents can become liable for tax due on money paid to others, and describes how the IRS is holding US withholding agents accountable for the tax liabilities of foreign payees.

Since their passage in 2012, Puerto Rico’s Acts 20 and 22, known together as Act 60 since 2019, have encouraged many individuals and businesses from the US mainland to relocate to Puerto Rico. The tax benefits that Act 60 provides encourage taxpayers outside Puerto Rico to boost the Puerto Rican economy by investing, doing business, and residing in Puerto Rico. As with any tax benefit, though, Act 60 is vulnerable to abuse. This panel discusses the IRS and the DOJ’s scrutiny of taxpayers’ claims of bona fide residency and Puerto Rico-sourced income.

Foster, Esq., Partner, Kirkland & Ellis, Washington, DC, S. Starling Marshall, Esq., Partner, Crowell & Moring, New York, NY, Joseph A. DiRuzzo, III, Esq., CPA, Partner, DiRuzzo & Company, Fort Lauderdale, FL

Ever since the Supreme Court rejected tax exceptionalism in Mayo Foundation v. United States, 562 U.S. 44 (2011), challenges to tax regulations and IRS notices have proliferated, with several important decisions coming out in the last year alone. Courts have now developed a full body of jurisprudence regarding application of the Administrative Procedure Act (“APA”) to tax cases and it appears that Treasury and the IRS are going to have to engage much more carefully with the APA as they issue new guidance. Have we reached the end of “tax exceptionalism”? What does Treasury’s “Policy Statement on the Tax Regulatory Process” mean for deference in tax litigation? How will the APA apply to the blizzard of new guidance under the TCJA and increasingly the IRA? What might a post-Chevron world look like if, as some anticipate, the Supreme Court overrules the seminal decision next term? This panel addresses these questions and explores the current state of the law on the APA as it applies to tax.

Wilson, CPA, Office Managing Partner, Marcum, Costa Mesa, CA , Adriana Wirtz, Esq., Partner, Vinson & Elkins, New York, NY

The EPA describes the Inflation Reduction Act of 2022 (“IRA”) as “the most significant climate legislation in US history, offering funding, programs, and incentives to accelerate the transition to a clean energy economy” and predicts that the Act will drive the deployment of new clean electricity resources. Under the IRA, certain businesses and tax exempt entities may deduct a percentage of the cost of renewable energy systems from federal tax and, in some cases, directly monetize or transfer tax credits to unrelated parties. With these tax benefits will come increased enforcement to ensure that taxpayers are not abusing the system. This panel addresses the various clean energy credits under the IRA, the eligibility and filing requirements, current and forthcoming Treasury and IRS guidance, and what we can expect in future audits and investigations.
