Frequently Asked Questions About Form 911
Form 911 has a Form Complexity Index of 48 out of 100, placing it in the moderate complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.
For Form 911 specifically, the score reflects 64 fillable fields across 4 pages, grouped into 18 sections, and 8 conditional fields that only apply depending on earlier answers. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.
In practical terms, a moderate score means the form takes real effort: there are enough fields, pages and rules that errors are easy to make by hand. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes Form 911 accurately in under a minute, with every field available for you to review before you download. See exactly how the Form Complexity Index is calculated.
Form 911 is used to request assistance from the Internal Revenue Service (IRS) Taxpayer Advocate Service (TAS) when taxpayers are experiencing economic harm or facing an immediate threat as a result of a tax issue, and have been unable to resolve the issue with the IRS.
Individuals, businesses, or their authorized representatives can file Form 911 if they believe they meet the criteria for TAS assistance. The form must be completed accurately and completely, with all required information and documentation attached.
Section I of Form 911 requires the taxpayer's name and identifying number, spouse's name and identifying number (if applicable), current mailing address, daytime phone number, email address, and preferred language (if applicable).
Section II of Form 911 is for third-party information, including the name, mailing address, and contact information of an authorized representative. If no representative is being used, this section should be left blank.
After Form 911 is submitted, the IRS will review the request and determine if the taxpayer meets the criteria for TAS assistance. If the request is approved, the TAS will work with the IRS to resolve the tax issue. If the request is denied, the taxpayer will be notified in writing.
The processing time for Form 911 can vary depending on the complexity of the tax issue and the workload of the TAS. Generally, taxpayers can expect to receive a response within 30 days, but some cases may take longer.
No, Form 911 cannot be filed electronically. It must be mailed to the address listed on the form or faxed to the number provided.
If you make a mistake on Form 911, you should correct it and resubmit the form as soon as possible. It is important to provide accurate and complete information to ensure that your request is processed efficiently.
The TAS may provide assistance if the taxpayer is experiencing economic harm or is about to suffer economic harm, facing an immediate threat, will incur significant costs if relief is not granted, or will suffer irreparable injury or long-term adverse impact if relief is not granted. The TAS may also provide assistance if the taxpayer has experienced a delay of more than 30 days to resolve a tax account problem, did not receive a response or resolution to their problem or inquiry by the date promised, or if the manner in which the tax laws are being administered raises considerations of equity or has impaired or will impair the taxpayer's rights.
If you don't receive a response within 30 days of submitting Form 911, call the TAS at 877-777-4778 for assistance.
Submitting multiple Form 911s for the same issue to different TAS offices will cause duplicate referrals and may delay the resolution of your issue.
The Paperwork Reduction Act Notice for Form 911 states that the information requested on the form is necessary to carry out the Internal Revenue laws of the United States and that the response is voluntary. The estimated average time to complete the form is 30 minutes.
The IRS will not consider frivolous arguments raised on Form 911. You can find examples of frivolous arguments in Publication 2105 or on the IRS website. If you use the form to raise frivolous arguments, you may be subject to a penalty of $5,000, in addition to any other penalty provided by law.
