Thorn Law Group Helps Tax Professionals Defend their Reputations and Livelihoods


When a tax professional’s license or a firm’s reputation is on the line, the best possible representation is necessary for dealing with government investigators.  At Thorn Law Group, we specialize in representing tax professionals, law firms, accounting firms, and other entities being investigated by government agencies concerning ethics issues, preparer penalties, and professional malpractice allegations.  Specifically, the firm has extensive experience in representing individuals and firms before the Internal Revenue Service, the Internal Revenue Service’s Office of Professional Responsibility (“OPR”) the Department of Justice (“DOJ”), the United States Tax Court, and other federal and state agencies. 

As former attorneys for the Internal Revenue Service, the United States Tax Court, and the Internal Revenue Service’s Office of Professional Responsibility, we know how government agencies’ conduct their investigations.  This knowledge enables us to advise our nationwide base of clients through the complicated investigatory procedures and help them present their cases in the best possible light.   Thorn Law Group is also uniquely positioned to assist tax practitioners in licensing and disciplinary matters arising from the recent IRS Return Preparer Initiative.

Thorn Law Group effectively represents our clients in the following areas:

If you are a tax professional (attorney, CPA, Enrolled Agent or Unenrolled Return Preparer), we can assist you with any disciplinary matters you have before the IRS Office of Professional Responsibility, State Bars or State Boards of Accountancy.

This is an area of ongoing activity by the IRS and the Department of Justice. Check out Kevin and the News & Events page for the latest developments.
