How to Fax IRS Form 911 to the IRS — Taxpayer Advocate Service Request
Form 911 asks the Taxpayer Advocate Service — an independent organization inside the IRS — to step in when you are facing economic harm or a tax problem that normal IRS channels have not resolved. TAS accepts Form 911 by fax, and the destination is the local Taxpayer Advocate office that serves your state. This guide covers finding your local office, faxing the request there, and keeping proof of when your hardship case was submitted.
Does the IRS accept a fax?
Yes — the Taxpayer Advocate Service accepts Form 911 by fax at your local Taxpayer Advocate office. TAS is part of the IRS but operates independently to help taxpayers whose issues are causing hardship or have stalled, and faxing gets the request in front of the office that will assign your case.
Finding the official fax number
Every state has at least one local Taxpayer Advocate office, and its fax number is listed through the TAS office locator on the IRS Taxpayer Advocate site and in IRS Publication 1546. Look up the office that serves your state in those sources rather than sending to a general IRS line, since Form 911 is worked by the local TAS office, not a central campus.
What to include on every page
- Your name, address, SSN or ITIN, and a phone number where TAS can reach you
- A clear description of the tax problem and the hardship or harm it is causing
- The specific relief you are asking the Taxpayer Advocate Service to help obtain
- The tax form and year involved, plus any related IRS notice or case number
- Your signature and date in Section I, or the representative's details in Section II

Send FAX Mail returns a dated confirmation as soon as the request reaches your local TAS office fax line — keep it while your case is opened. The Taxpayer Advocate Service reviews Form 911 requests and typically follows up by phone once a case advocate is assigned, so the confirmation documents exactly when you asked for help if timing matters to your hardship.

Federal agencies still write fax into new rules and notices
The Federal Register — the daily journal of U.S. federal rulemaking — regularly publishes rules and notices that reference fax as an accepted or required submission channel for filings with agencies like the IRS, SSA, and CMS. That is why fax remains a live requirement for many official forms even as electronic portals expand.

Faxing IRS Form 911 (Request for Taxpayer Advocate Service Assistance) to the IRS — FAQ
Yes. TAS accepts the request by fax at the local Taxpayer Advocate office for your state, and it is a common way to reach them quickly when an IRS problem is causing real hardship. Faxing puts the request directly with the office that will assign a case advocate to you.
The TAS office locator on the IRS Taxpayer Advocate website, and IRS Publication 1546, list a local office and its fax number for every state. Use those to identify the office that covers your area — Form 911 is handled locally, so a general IRS fax line would misroute it.
TAS is meant for situations where you are facing economic harm, an IRS action threatens immediate hardship, or normal channels have failed to resolve a problem. If your issue is routine and moving along, standard IRS processing usually applies; Form 911 is for cases that genuinely need an advocate.
The service reviews the request and, when it takes the case, assigns a case advocate who generally contacts you by phone to work the issue. Your dated fax confirmation shows when the request went in, which can matter when a deadline or a pending IRS action is driving the hardship.
