How to Fax Form 911 to the Taxpayer Advocate Service

Form 911 requests help from the Taxpayer Advocate Service when an IRS problem is causing serious hardship, has not been resolved through normal channels, or involves a breakdown in the usual process.

TAS is an independent organization within the IRS. It does not replace an appeal, extend every deadline, or guarantee a particular tax result.

Check whether Form 911 fits the problem

Read the criteria on the current Form 911. Examples include an immediate threat of adverse action, significant costs if relief is not granted, a delay of more than 30 days, or repeated failure to receive a promised response.

Describe the problem in plain language. Include the tax form and years involved, the hardship or delay, steps already taken, and the specific assistance you want from TAS.

Current Form 911 fax numbers

The August 2025 revision lists these central destinations:

• Within the United States: 855-828-2723.
• From outside the United States: 304-707-9793.

Check the form again before sending. If a local TAS office or advocate has already given you a direct number, use the instructions from that contact.

Prepare and send the request

1. Complete your identifying and contact information.
2. Explain the tax issue and how it is affecting you.
3. State the relief or action you are requesting.
4. Sign and date the taxpayer section.
5. Attach only the documents needed to understand the problem.
6. Scan everything into one readable PDF and fax it once.
7. Save the sent file and delivery confirmation.

The form also provides an email submission option, but it warns that emailed submissions and attachments are not encrypted. Fax may be the simpler choice for documents containing tax identifiers.

What happens after submission?

TAS says it will contact you after receiving a request that meets its criteria. The form instructs applicants who have not heard back within 30 days to follow the follow-up directions rather than submitting duplicate Forms 911.

Continue responding to any active IRS deadline unless TAS or the IRS tells you otherwise.
