Miller & Chevalier's Tax Controversy and Litigation team is among the very best in the country according to Chambers USA. They note that "The team is very cohesive and thoughtful, and is very talented at thinking through issues," and that they "simplify very complex tax concepts into concise arguments." This is why many of the world's largest multinational corporations turn to the firm to take on their most significant domestic and cross-border controversies. We have been successfully resolving major tax disputes for our clients since our founding in 1920, including some of the most complex and significant matters on record.

Our tax lawyers combine deep technical tax knowledge with rich experience in all facets of controversy and litigation. Many of our lawyers draw on previous experience working in government to provide insight into resolving complex conflicts. Over the last two decades, Miller & Chevalier lawyers have litigated more than one hundred tax cases in the federal courts. As an example, our lawyers just litigated a multi-billion-dollar transfer-pricing case for a Fortune 100 company in a Tax Court trial that lasted two months. 

In recent years, we have taken cases to trial in the Court of Federal Claims, and in district court as well as the Tax Court. And we have significant experience and a successful track record in appeals to the circuit courts and the Supreme Court. Recent cases have involved the gamut of tax issues, including tax accounting, cost basis and valuation, treaty benefits, tax credits, interest netting, and transfer pricing.

When clients seek to resolve disputes short of litigation, we are adept in all forms of administrative dispute resolution, from Fast Track Settlement to Early Referral to Appeals, traditional appeals, Post-Appeals Mediation, the Compliance Agreement Program (CAP), the Pre-Filing Agreement program, and Advance Pricing Agreements.
