Title 26 › Subtitle Subtitle F— Procedure and Administration › Chapter 74— CLOSING AGREEMENTS AND COMPROMISES › § 7121
The IRS can sign a written closing agreement with any person settling that person's tax liability for any period. Once approved, the agreement is final and conclusive for both sides. Unless someone shows fraud, malfeasance, or misrepresentation of a material fact, no government officer can reopen the settled matters or change the agreement, and no court proceeding can annul, modify, or set aside the agreement or anything done under it, such as an assessment, payment, or refund.
