What is the Taxpayer Advocate Service?

The Taxpayer Advocate Service (TAS) is an independent organization within the IRS, separate from the examination, collection, and customer service functions you'd normally deal with. Its job is to step in when you're facing significant hardship, meaning you can't provide the necessities of life for yourself or your family because of an IRS action or delay, or when you've tried to resolve a problem through the normal IRS process and it simply isn't working.

Form 911, Request for Taxpayer Advocate Service Assistance, is how you formally ask TAS to open a case. Once TAS accepts your case, you're assigned a single advocate who works your issue directly with the IRS on your behalf, rather than routing you through general phone queues each time you follow up.

Form 911 Fax Number

Form 911 goes to one centralized Taxpayer Advocate Service fax number for the vast majority of filers, confirmed directly on the form's own printed instructions:

855-828-2723 (domestic, all 50 states)

Two regional exceptions exist based on time zone rather than state: taxpayers in Puerto Rico and nearby time zones (GMT +6 to -4) fax to 855-818-5700, and taxpayers in Hawaii and nearby time zones (GMT +7 to -11) fax to 855-819-5024. Filing from overseas uses a separate, non-toll-free number: 304-707-9793.

Unlike some other items in this collection, Form 911 intake genuinely is centralized rather than routed by local office, so you don't need to look up your state's Taxpayer Advocate office to submit your initial request. Local TAS offices do still exist and matter later, once your case is open, your assigned advocate may ask you to send follow-up documents to their office directly, but the number above is the correct one for filing Form 911 itself.

Why does filing Form 911 matter?

Without Form 911, an unresolved IRS problem stays in the general system, worked (or not worked) in whatever order the IRS gets to it, with no single person accountable for your case. Filing Form 911 gets you a dedicated case advocate whose job is specifically to push your issue forward and, where appropriate, request that the IRS pause an action causing you hardship while your case is being worked. For a hardship situation with a clock already running, that dedicated attention can be the difference between resolving the issue in time and having it escalate.

Who should file Form 911?

Anyone experiencing significant hardship because of an IRS action or delay, meaning you can't provide necessities like housing, food, transportation, or medical care as a result.
Anyone whose IRS issue hasn't been resolved through the normal process, despite reasonable attempts, including delays well past the IRS's own stated timeframes.
Anyone facing an IRS action they believe is about to cause irreparable harm, such as an impending levy or garnishment, and needs help before that action takes effect.
An authorized representative filing on a taxpayer's behalf, with a completed Form 2848 or Form 8821 attached.

Frequently Asked Questions About the Form 911 Fax Number

What counts as a "significant hardship" for Taxpayer Advocate Service help?

Significant hardship generally means an IRS action or delay is preventing you from providing necessities like housing, food, transportation, or medical care for yourself or your family, or that you're about to suffer serious harm, such as an imminent levy, if the IRS doesn't intervene. You don't need to already be in crisis to qualify, an unresolved issue with real financial consequences closing in is enough.

How is the Taxpayer Advocate Service different from calling the regular IRS helpline?

The regular IRS phone line routes you to whichever representative is available, with no guarantee you speak to the same person twice or that anyone owns your case specifically. TAS assigns you one advocate who stays with your case from open to close, works directly with the relevant IRS department on your behalf, and can use tools like a Taxpayer Assistance Order that a general phone representative can't invoke.

What happens after I submit Form 911?

A case advocate typically makes initial contact within 30 days of TAS receiving your request, sooner for urgent hardship cases. From there, your advocate works directly with the relevant IRS function to resolve your issue and keeps you updated, rather than you having to call in repeatedly to check status.

Can the Taxpayer Advocate Service stop an IRS collection action while my case is open?

In genuine hardship situations, TAS can request a Taxpayer Assistance Order directing the IRS to pause or reverse a collection action, such as a levy or wage garnishment, while your case is being worked. This doesn't erase or reduce what you owe, it buys time and prevents further harm while the underlying issue gets sorted out.

Does it cost anything to use the Taxpayer Advocate Service?

No. TAS is a free service funded as part of the IRS, not a paid tax-resolution firm. There's no fee to file Form 911 or to have an advocate work your case, which is worth knowing given how many paid services market themselves using similar "advocate" language.
