When Form 911 Is the Right Form
Form 911 is the Request for Taxpayer Advocate Service Assistance. The Taxpayer Advocate Service, or TAS, is the office inside the IRS that helps when a tax problem is not getting resolved through the normal IRS channels. You fill in the form, describe the problem and what you have already tried, and send it to TAS rather than to the unit you have been dealing with.
Use the current revision of the form (Rev. 6-2026 at the time of writing), because the contact details on older copies may not match. The form itself lists where to send it.
The rule: fax 855-828-2723 from inside the United States and 304-707-9793 if you are overseas. If a TAS advocate gives you a direct fax number, use that one.
Form 911 Fax Numbers and Other Routes
| Route | Where to send | Type this |
|---|---|---|
| Fax | 855-828-2723 | 8558282723 |
| Fax, overseas (not toll-free) | 304-707-9793 | 3047079793 |
| tas.form.911.request.for.assistance@irs.gov | ||
| Local TAS office | TAS Contact Us page, or call 1-877-777-4778 |
The form shows the overseas number as 1 (304) 707-9793. The 1 is the US country code: with OverseasFax you select United States and type only the 10 digits. Form 911 also lists a mailing address; take it from the current form itself, because the address shown on the form and on the TAS FAQ page are not the same.
For other IRS forms and notices, see our hub on how to fax the IRS.
Sending to Your Local TAS Office
You may also email, mail or fax Form 911 to your local TAS office. Find it on the TAS Contact Us page, or call 1-877-777-4778 and ask for the office that covers you. If you already have an advocate assigned, ask them which fax number they want you to use for follow-up pages.
If you live outside the United States, the overseas fax, 304-707-9793, is the simplest route. For account questions that have not yet reached the point of needing TAS, the IRS international line, 267-941-1000, and its fax are covered in our guide to IRS international accounts.
What to Put on the Pages
A short cover page addressed to the Taxpayer Advocate Service with your name, the identifying number used on your tax records, the tax years involved, a phone number with country code, the best time to reach you, and the date. List what is attached.
Then Form 911, completed and signed where the form asks. Copies of the IRS notices or letters about the problem help the advocate see what is going on, and so does a short timeline of the calls and letters so far. If someone is representing you, the form asks about that too; see our guide to Form 2848. If the problem is identity theft on your tax account, our guide to Form 14039 covers that form's own fax.
Put your name and identifying number at the top of every page, and scan to PDF rather than photographing pages so small print stays readable in black and white.
Entering the Number From Abroad
Both Form 911 fax numbers are US numbers. Select United States from the list, then type the 10 digits: 3047079793 for the overseas line, or 8558282723 for the main fax. No leading 1, no spaces and no dashes. Our guide to faxing to the USA covers the format, and our guide to sending a fax from outside the United States covers paying and uploading from another country.
From the US or anywhere else in the world, OverseasFax is built for this.
Cost, Delivery and Your Record
US numbers are $2.99 for up to 3 pages, then $0.99 per extra page. A typical Form 911 fax, for example a cover page, the form and copies of two IRS notices, comes to about 5 pages: $4.97. You see the price before you pay.
There is no account, nothing is printed on your document, and delivery usually takes a few minutes. The confirmation email shows the destination number, the page count and the time it went through, in US Eastern Time: your record of exactly when it was sent. If the fax cannot be delivered, you are refunded automatically.
If your advocate wants to fax documents back to you, our sister service GetAFax.com gives you a US fax number for 24 hours for $5, and faxes arrive in your email.
