Marc Sellers helps clients resolve “make or break” civil and criminal tax issues in state and federal courts. In his 36-year career he has obtained successful results for hundreds of clients, including the first award of attorney fees against the Internal Revenue Service under the IRS Restructuring and Reform Act of 1998.

Marc represents clients in tax and related financial cases before the United States Tax Court, the U.S. District Courts in Oregon, Washington and California,, the U.S. Court of Appeals for the Ninth Circuit and the U.S. Court of Federal Claims, and state courts. He also assists clients with a wide variety of tax matters before administrative agencies in Oregon, Washington and California. 

In addition to his tax controversy and litigation work, since 1980 Marc has as also practiced as a tax planning and transactional tax attorney. The combination of these two distinct, but related, areas of tax practice enable him to understand the business aspects of tax controversies and offer unique, creative solutions.

Marc’s practice also encompasses non-tax controversies involving import-export regulations, environmental laws, the Endangered Species Act, RICO and white-collar criminal controversies.
