How to Fax Form 911 to the Taxpayer Advocate Service
Updated October 2026
You are stuck on an IRS problem and want the Taxpayer Advocate Service (TAS) to step in. Fax Form 911 to (855) 828-2723, the TAS fax number printed on the current form (Rev. 6-2026), and it costs $1.00 here for up to 10 pages.
Quick answer: Fax your completed Form 911 to (855) 828-2723. If you are outside the US, the form lists 1 (304) 707-9793, which is not toll-free but is still a US number, so it is also $1.00 here. You can also email it to tas.form.911.request.for.assistance@irs.gov or send it to your local TAS office. No account, nothing printed on your form, automatic refund if it fails.

Where to Fax Form 911
Form 911 lists one main fax number and one for taxpayers overseas. You can also email it, or email, mail or fax it to your local TAS office.
| Route | Number or address | Type this here |
|---|---|---|
| TAS fax (main) | (855) 828-2723 | 8558282723 |
| TAS fax (overseas, not toll-free) | 1 (304) 707-9793 | 3047079793 |
| tas.form.911.request.for.assistance@irs.gov | Not a fax | |
| Your local TAS office | TAS Contact Us page, or call 1-877-777-4778 | The number the office gives you |
If you would rather work with the advocate office closest to you, find it on the TAS Contact Us page or call 1-877-777-4778 and ask for that office's fax number. We do not list a mailing address here on purpose: the form and the TAS website do not give the same one. If you want to mail it, call 1-877-777-4778 first and ask which address to use. Fax and email skip that question.
How to Type the Number
Type the 10-digit number with the area code and nothing else. We already add the +1, so do not type a leading 1, even for the overseas number that the form writes as 1 (304) 707-9793. For the main line, type 8558282723. For the overseas line, type 3047079793.
It does not matter where you are sending from. Both numbers are in the US, so the price is $1.00 for up to 10 pages whether you are in Ohio or overseas. You only need our sister service OverseasFax.com when the number you are faxing is outside the US and Canada.
What to Put on the Cover Page and Each Page
Get the current form from irs.gov/pub/irs-pdf/f911.pdf, fill in every section that applies to you, and sign and date it where the form asks. Then scan it with the pages that show the problem.
On the cover page, write "Form 911, Request for Taxpayer Advocate Service Assistance", your name, the last four digits of your Social Security number or EIN, the tax year or years involved, the number of pages that follow, and a daytime phone number with the best time to reach you. Behind Form 911, add copies of the IRS notices or letters about the problem and anything that shows the harm the delay is causing you.
On every page after the cover, write your name and the last four digits of your taxpayer ID in the top margin. Faxed pages get separated, and a page with no name on it is hard to match back to your case.
If a tax professional is sending it for you or will speak with TAS for you, our Form 2848 and 8821 guide covers the authorization forms.
What It Costs
Form 911 plus a few copies of IRS letters almost always fits in 10 pages, so most people pay $1.00. If you attach a thick stack of notices, 11 to 25 pages is $1.99 and 26 to 50 pages is $2.99. The price is shown before you pay, and there is no account, no subscription and nothing that renews.
Emailing the form to TAS costs nothing, and it is a fine choice if you prefer it. People fax because they want a confirmation that shows the exact number it went to, how many pages went through, and when.
Timing and Your Record
Form 911 asks TAS for help. It does not replace answering the IRS. Keep responding to every IRS notice by the date printed on it while you wait to hear from an advocate. If your problem is a CP2000, our CP2000 response guide lists the fax number for each notice location.
Your fax is usually delivered within a few minutes. You then get a confirmation email with the destination number, the page count and the time it was sent, in Eastern Time. That email is your record of exactly when it was sent. It is not an acknowledgment from the IRS, so save it with your copy of the form. If the fax cannot be delivered, your money goes back to your card automatically and you can send it again.

Getting a Reply
TAS decides how it contacts you, so put a phone number on your cover page and answer calls from numbers you do not recognize for a while. If an advocate offers to fax you something and you have no fax machine, our sister service GetAFax.com gives you a US fax number for 24 hours for $5. Up to 30 pages can come in, and they arrive in your email.
