What you need to know

If we previously sent you a Statutory Notice of Deficiency (sent by certified mail), it lists the last day to petition the Tax Court. The court can't consider your case if you file the petition late. For more information about petitioning the Tax Court, review page 5 of Publication 3498-A, The Examination Process PDF or visit United States Tax Court.
