Fax Form 911 to the Taxpayer Advocate Service

To fax Form 911, complete the form, sign it, and send it to the Taxpayer Advocate Service (TAS) at (855) 828-2723. If you are sending from outside the United States, the number is 1 (304) 707-9793. Keep the transmission confirmation report, because the IRS does not send its own acknowledgment. This guide covers who should file, how to fill out the form, how to confirm the fax went through and what to do if you hear nothing back.

TL;DR

Form 911 (Rev. 6-2026) is the request for Taxpayer Advocate Service assistance. The official form is the version to use.
The domestic TAS fax number is (855) 828-2723. Fax from overseas to 1 (304) 707-9793. Both come from TAS and the form instructions.
Complete every line, sign and date, and send only the form unless a representative needs to include Form 2848 or Form 8821.
Save the fax confirmation report. It is your only immediate proof of delivery.
If a case advocate has not contacted you within 30 days, follow up with the TAS office where you filed. Do not file a second Form 911 for the same issue.

What Form 911 is and who should file it

Form 911 is titled “Request for Taxpayer Advocate Service Assistance (and Application for Taxpayer Assistance Order).” TAS is an independent organization inside the IRS. It helps taxpayers resolve federal tax problems and protects their rights, according to the form itself.

TAS may be able to help in three situations:

A federal tax problem is causing you financial difficulty.
You have tried to resolve the issue with the IRS and could not.
An IRS system, process or procedure is not working as it should.

The TAS Taxpayer Rights page describes significant hardship in the same terms. It also confirms that you have the right to ask TAS to issue a Taxpayer Assistance Order.

Form 911 is not a substitute for every IRS remedy. TAS does not give legal advice and cannot reverse Tax Court or Appeals decisions. If your issue is a lien or levy, this overview notes that a Collection Due Process request on Form 12153 is a separate route that generally pauses collection. A tax professional or attorney can tell you which route fits your case.

The form also carries a warning. TAS will not consider frivolous arguments, and using the form to raise them may result in a $5,000 penalty, per the instructions.

Where to fax Form 911

The numbers depend on where you are sending from.

Situation	Fax number	Source
Within the United States	(855) 828-2723	TAS submit page
From outside the United States	1 (304) 707-9793 (not toll-free for U.S. taxpayers)	Form 911 instructions

TAS also lists offices for taxpayers who live far from the mainland. If you reside between GMT +6 and -4, contact the Puerto Rico office at (855) 818-5700 or (866) 743-5220. If you reside between GMT +7 and -11, contact the Hawaii office at (855) 819-5024. The same page tells you to submit the form to the TAS office nearest you.

Older pages and PDFs still circulate with other fax numbers, including local office numbers. Before you send anything with personal tax details, check the number against the TAS website. TAS advises going to the Contact Us section, finding the local TAS office listing and confirming that the address, telephone and fax numbers match. Its page on verifying TAS contacts also notes that legitimate TAS email addresses end in @irs.gov.

For other IRS fax destinations, see our IRS fax numbers guide and the IRS fax number lookup reference.

Other ways to submit

Fax is one of three methods the form accepts. The others are:

Email: tas.form.911.request.for.assistance@irs.gov. The instructions note that email submissions and attachments are not encrypted.
Mail: Taxpayer Advocate Service, 7940 Kentucky Dr., MS 11 G, Florence, KY 41042.

Fax is a common choice when the matter is urgent. The IRS Internal Revenue Manual says that for faxed or emailed forms, the date TAS received your request is the date the fax or email was submitted. It also says no date stamp is needed for those submissions. A faxed form is therefore dated the day you send it, not the day someone opens a mailbag.

Fill out Form 911 before you fax it

TAS asks that the form be filled out completely before it is submitted so that it can start working the issue as soon as possible. The steps below follow the order of the form.

Section I: your information. Enter your name, taxpayer identification number, address and a phone number where TAS can reach you. If you are filing for a business, use the business details.
Identify the tax form and period. Name the return or notice involved, such as Form 1040 for a specific tax year.
Describe the problem and the hardship (line 12a). Say what happened, what you already tried with the IRS and how the problem affects you financially. Specific facts help more than general statements.
State the relief you want (line 12b). Say exactly what you are asking TAS to help with, for example releasing a levy or resolving a delayed refund.
Consent for voicemail (line 7b). TAS usually contacts you by phone first. According to one explanation of the process, confidential details are left on voicemail only if you checked the Line 7b consent box.
Sign and date. An unsigned form is one of the most common reasons a request stalls.

If a representative is submitting for you, a signed Form 2848 or Form 8821 must be on file or included. The same guide lists mistakes that delay processing: filing before trying the IRS, vague explanations, leaving out the hardship, missing signatures or authorization, and sending duplicates.

What to attach

TAS asks you to include only Form 911 and not other IRS forms or notices. Keep your notices and prior correspondence organized so you can give them to the case advocate when asked. If a representative is acting for you, include the authorization form described above.

Page count and cost

Count every page, including the fax cover sheet. A cover sheet is optional but useful because it tells TAS who the fax is from and how many pages to expect. Our free fax cover sheet builder creates one as a PDF. At $0.50 per page, a six-page fax costs $3.00.

Send the fax and keep proof

The IRS does not send an acknowledgment fax or confirmation email for Form 911, according to one summary. The transmission confirmation report from your fax machine or online service is therefore the only immediate record. Save or print it and file it with your copy of the form.

The report usually shows one of these statuses:

OK or Success: the receiving machine accepted the data.
BUSY: the line was occupied. Retry after a short wait.
NO RESPONSE: check the number you dialed and send again.
FAIL with a code: this can point to a line quality problem or an interruption on the receiving side. Verify the number and resend after a short interval.

The same source notes that a fax report does not carry the legal presumption of a certified mail receipt under Treasury Regulation 301.7502-1. If a deadline is involved, ask your tax professional whether you should also send the form by a method that gives you that protection.

Our guides on downloading an IRS fax confirmation, getting a fax transmission report without a machine and keeping fax receipts for audits explain how to store this proof.

After you fax: what to expect

TAS says a case advocate will reach out within 30 days. Behind the scenes, an intake employee reviews the request and checks your account in IRS systems. According to one description of the process, accepted requests are usually routed within one workday to a local office, often by zip code. If TAS does not accept the request, it generally sends a letter explaining the decision.

TAS intake, routing, and response timeline

Contact usually starts by phone. If TAS cannot reach you, it sends a letter. Keep your phone available and check your mail.

If your issue involves imminent collection action such as a levy or lien, the IRM describes special procedures to elevate emergency cases. Say plainly on the form what the deadline or action is.

If 30 days pass with no contact

Contact the TAS office where you submitted the request, as the TAS submit page directs.
Or email tas.form.911.request.for.assistance@irs.gov with “No Response” in the subject line, as the form instructions describe.
You can also call TAS at 1-877-777-4778. TAS warns that wait times can be long because of high volume.
Do not send another Form 911 for the same issue. The instructions warn that duplicates may cause delays.

Protect your information when you fax

Form 911 contains your taxpayer identification number, address and details about your finances. Three habits reduce risk:

Confirm the number before sending. Compare it with the TAS website, as described above.
Choose a secure method. Email is not encrypted, so if privacy is the concern, fax or mail are the alternatives. Our service encrypts faxes in transmission.
Know how TAS contacts you. TAS says its employees must protect tax information and share it only after authenticating your identity. A real TAS employee gives a name, job title, office address, phone number, office hours and a ten-digit badge number, per the TAS page on verifying calls. If anything doesn’t match, call the local office number listed on the TAS website.

Perspective

Form 911 requests are often sent under pressure: a levy notice, a refund that never arrived, a deadline close at hand. In those moments, people need a fax method that is simple and that gives them something to keep.

That is why we built PerPageFax around a flat $0.50 per page, with no account and no subscription. You upload the PDF, enter the TAS number, pay for the pages you send and receive delivery confirmation. Our service is designed to retry automatically if the line is busy, and a failed fax is refunded.

The practical advice is the same whatever tool you use: verify the number on the TAS website, count your pages, keep the confirmation report and send one complete form rather than several partial ones.
