IRS Form 911 – Request for Taxpayer Advocate Service Assistance (And Application for Taxpayer Assistance Order)

You may submit form 911 if an IRS office:

  • will not grant the assistance requested; or
  • will not grant the assistance in time.

The Taxpayer Advocate Service (TAS) generally requests that certain IRS collection activities be stopped while your request for assistance is pending (e.g., lien filings, levies, and seizures).

Use this form if any of the following apply to you:

  1. You are experiencing or are about to suffer economic harm.
  2. You are facing an immediate threat of adverse action.
  3. You will incur significant costs if relief is not granted (including fees for professional representation).
  4. You will suffer irreparable injury or long-term adverse impact if relief is not granted.
  5. You have experienced a delay of more than 30 days to resolve a tax account problem.
  6. You have not received a response or resolution to your problem or inquiry by the date promised.
  7. A system or procedure has failed to:
    1. operate as intended; or
    2. resolve your problem or dispute within the IRS.
  8. The manner in which the tax laws are being administered:
    1. raise considerations of equity, or
    2. have impaired or will impair your rights.
  9. The National Taxpayer Advocate determines compelling public policy warrants assistance to an individual or group of taxpayers.

“Economic harm” generally means utility cutoff, eviction, and similar events.
