Tax controversies are more than a bump in the road—they can stop an initiative or an entire enterprise in its tracks. As the Internal Revenue Service (IRS) increases its pursuit of big-ticket issues, national and multinational corporations require immediate, sophisticated responses from legal advisors with a deep understanding of the methods and goals of the IRS and the skills and experience to mount an effective defense. McDermott’s Tax Controversy practice is notable for the sophistication and skills of our team, the depth of our experience and our proven track record of delivering results for clients.
McDermott represents clients on all aspects of federal, state and local, and international tax controversy matters, including IRS audits and appeals, competent authority matters, and trial and appellate litigation. We are also experienced with the numerous alternative dispute resolution options available to taxpayers during the audit and appeals process.
Chambers USA has perennially ranked McDermott’s Tax Controversy practice in its highest tiers, with clients noting that our attorneys “provide a lot of good market knowledge.” The Legal 500 has also recognized McDermott as a leading firm in the tax controversy area, noting that we provide “excellent services for reasonable fees.” US News-Best Lawyers recently named McDermott “Tax Litigation Firm of the Year.”
Our tax controversy lawyers regularly represent some of the world’s largest corporations on complex tax issues, often with hundreds of millions of dollars under scrutiny. However, most tax controversy matters can be successfully resolved before going to court. When administrative settlement is not possible, we have extensive experience representing our clients in tax litigation at the trial and appellate levels, including before the US Supreme Court.
