Global Tax Controversy and Litigation



Gibson, Dunn & Crutcher’s Global Tax Controversy and Litigation Practice Group represents multinational corporations, privately held companies, investment funds, partnerships, sovereign wealth funds and individuals in resolving a broad range of complex domestic and cross-border tax disputes.  We work with clients at all stages of tax controversy, ranging from audit and administrative resolution through trial court proceedings and judicial appeal.  We also have extensive experience in resolving uncertain tax positions through letter rulings and other procedures available to secure advance guidance and direction from relevant tax authorities, helping our clients to avoid or mitigate the risk of tax controversies before they arise.  Our tax controversy and litigation lawyers work closely with the firm’s market-leading corporate, commercial litigation, intellectual property, appellate and other practices in a variety of contexts, including disputes with national, regional and local tax authorities and in contentious tax matters involving private parties.

The Global Tax Controversy and Litigation team is led by renowned tax litigators with decades of experience handling the largest and most complex cases and working at the highest levels of government, including the former Chief Counsel of the U.S. Internal Revenue Service.  Our clients come from a range of industries, including technology, pharmaceutical and medical device, consumer goods, electronic commerce, oil & gas, and financial services, among others.  The issues we handle reflect the broad scope of the tax law and include cross-border transfer pricing with a focus on valuing intangible property, the tax treatment of various in-bound and out-bound transfers and investments, partnership tax issues, tax accounting matters, employment taxes and employee benefits, renewable energy credits and other business tax incentives, investigations, and other tax-related compliance matters for public companies and other regulated entities.

In an increasingly interconnected global economy, our experience extends to high-stakes tax controversy matters across Asia, Europe and the Americas.  In the United States, the team handles federal, state and local tax audits, administrative appeals in the IRS’s Independent Office of Appeals, and litigation before various federal and state trial and appellate courts, including the United States Supreme Court, the federal courts of appeal, the U.S. Tax Court and the Court of Federal Claims.  Collaborating with other firm practice groups has proven valuable in securing favorable outcomes and court victories in forums ranging from administrative examinations through the U.S. Supreme Court.
