Dwight Mersereau is a Tax Group partner in Crowell & Moring's Washington, D.C. office. Dwight represents large, multinational corporate clients in high-stakes policy, planning, and controversy matters. These projects typically involve complex, highly technical tax accounting issues involving billions of dollars. Dwight is involved in shaping tax policy through legislation, U.S. Department of the Treasury regulation projects, revenue rulings, and private letter rulings. He has represented individual clients, industry associations, and client coalitions before Congress, the Treasury, and the Internal Revenue Service (IRS). Over the years, Dwight has fostered close working relationships with officials at the IRS and Treasury. He is often consulted by policy makers grappling with difficult tax accounting issues.
Dwight also represents clients involved in controversy with the IRS at all levels of the proceedings, including during examination, at appeals, and in litigation before the U.S. Tax Court. He achieves impressive results for his clients because of his depth of understanding of complex tax accounting issues gained through his more than 20 years of experience in dealing with all aspects of the law, which he first obtained in drafting tax accounting guidance while serving in the Office of Chief Counsel.
Recent cases have involved leading manufacturers, financial institutions, retailers, and construction companies, and included issues involving accounting for credit card fees; original issue discount; accounting for research and development expenses; capitalization and amortization of intangibles; last-in, first-out (LIFO) inventory accounting; income deferral; uniform capitalization costs of inventory and self-constructed assets; the “production deduction” under Section 199 of the Internal Revenue Code; the percentage-of-completion method; and depreciation. Dwight is adept at using various settlement tools, including Fast Track settlement, Industry Issue Resolution (IIR), and alternative timing settlements.
Dwight has been named a recognized practitioner in the tax field by Chambers USA.
Dwight began his career as an appellate and trial lawyer in the Office of the Judge Advocate General in the United States Navy. In addition to briefing dozens of cases, he has orally argued 10 cases before the U.S. Court of Appeals for the Armed Forces and the Navy-Marine Corps Court of Military Review. Dwight rose to head trial counsel at the Charleston Naval Base and was the lead prosecutor in more than 50 felony cases.
While in the IRS Office of Chief Counsel, in the Office of the Associate Chief Counsel (Income Tax & Accounting), the chief counsel awarded Dwight the Technical Guidance Award for his publication of comprehensive guidance for accounting method changes.
Dwight is a frequent writer and lecturer on tax accounting issues. From 2003 to 2005, he was an adjunct professor of law at the Georgetown University Law Center, where he taught Income Tax Accounting in the Masters of Law Program.
