Tax Controversy and Litigation | Practices

At Holland & Knight, we have a nationwide network of tax controversy and tax litigation attorneys. We represent various types of domestic and foreign taxpayers, including individuals, businesses of all sizes and types, tax-exempt entities, trustees and executors, and Native American tribes.

Our team represents clients before federal and state taxing authorities, with the objective of resolving disputes prior to litigation. At times, litigation is unavoidable or in the client’s best interest. We have substantial experience litigating tax cases across the country in state and federal courts, including the U.S. Tax Court, U.S. Court of Federal Claims, U.S. District Courts and U.S. Circuit Courts of Appeals.

Holland & Knight’s tax controversy and litigation attorneys have strong relationships with auditors, tax officials and public officials throughout the United States. We also work closely with tax directors, chief financial officers (CFOs), accountants and outside auditors to ensure that our clients are thoroughly and zealously defended during the audit and litigation process.
