Photographs of Missing Children

The Internal Revenue Service is a proud partner with the National Center for Missing and Exploited Children. Photographs of missing children selected by the Center may appear in instructions on pages that would otherwise be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.

Unresolved Tax Issues

The Taxpayer Advocate Service (TAS) is an independent organization within the IRS whose employees assist taxpayers who are experiencing economic harm, who are seeking help in resolving tax problems that have not been resolved through normal channels, or who believe that an IRS system or procedure is not working as it should. The service is free, confidential, tailored to meet your needs, and is available for businesses, as well as individuals.

The cooperative can contact the TAS as follows.

  • Call the TAS toll-free case intake line at 1-877-777-4778 to see if the cooperative is eligible for assistance. Individuals who are deaf, hard of hearing, or have a speech disability and who have access to TTY/TDD equipment can call 1-800-829-4059.

  • Call or write the cooperative's local taxpayer advocate, whose phone number and address are listed in the local telephone directory and in Pub. 1546, Taxpayer Advocate Service—Your Voice at the IRS.

  • File Form 911, Request for Taxpayer Advocate Service Assistance, or ask an IRS employee to complete it on the cooperative's behalf.
