id="en_US_2025_publink100083652"> By mail. We handle many examinations and inquiries by mail. We will send you a letter with either a request for more information or a reason why we believe a change to your return may be needed. You can respond by mail or you can request a personal interview with an examiner. If you mail us the requested information or provide an explanation, we may or may not agree with you, and we will explain the reasons for any changes. Do not hesitate to write to us about anything you do not understand.
