We are tax dispute advocates for corporations, partnerships, trusts, estates, foundations and tax-exempt entities, and individuals. We handle Internal Revenue Service audits, protest letters and position papers contesting tax adjustments and penalties, administrative proceedings, assessment appeals, federal and state tax refund and deficiency litigation, and estate and gift tax disputes that include the valuation of closely held and family businesses. When tax disputes become lawsuits, we represent clients in the United States Tax Court, the U.S. Court of Federal Claims, and federal district courts. In addition to our civil tax practice, we represent clients facing criminal investigations and prosecutions for alleged tax offenses, as well as related white collar criminal charges.
