IRS-Faxnummern: Wie und wohin kann man ein IRS-Steuerformular faxen?

1. 844-253-2553: initial-year filers only (nationwide fax number for the separate Office of Tax Shelter Analysis copy)

This number is a temporary IRS procedure, in effect since October 1, 2020 "until further notice," and it is not a general submission line, it is only for faxing the separate OTSA copy of a reportable transaction's initial year Form 8886. You must still attach the original Form 8886 to your income tax return, that filing is never done by fax. If you already mailed or faxed your OTSA copy for a transaction's initial year, do not fax a second copy in a later year. Send only one exact copy per fax, up to a maximum of 100 pages, with a cover sheet listing the subject, your name, title, phone number, address, the taxpayer's name, the date, and the total page count (no EIN or SSN on the cover sheet). The IRS does not provide a fax confirmation or receipt, so keep your own transmission log.

1. 844-253-5607: all material advisors (toll-free number for faxing a complete, signed Form 8918)

This is a current IRS procedure for faxing Form 8918 in place of mailing it, in effect "until further notice." You must sign the form before faxing it, the IRS will not accept an unsigned copy. Send only one Form 8918 per fax, up to a maximum of 100 pages, with a cover sheet listing the subject, your name, title, phone number, and address, the material advisor's name, the date, and the total page count (no EIN or SSN on the cover sheet). The IRS does not provide a fax confirmation or receipt, so keep your own transmission log. After processing, the IRS mails a Letter 4373 with your reportable transaction number, which you must then pass on to every taxpayer and material advisor you acted for.

Include a fax cover sheet with your contact information and any necessary details to ensure proper processing of your submission.

1. 855-214-7523: All U.S. states and territories, fax directly to the IRS RAF Team in Ogden, UT

This is the only fax number for Form 8655, verified against the form's own filing instructions and IRS Publication 1474, with no state or regional split. Fax only to the RAF Team, faxing Form 8655 to any other IRS office does not satisfy your filing requirement. Send no more than 25 forms in a single fax, and the IRS itself recommends sending straight from your computer rather than a physical fax machine. You can also mail Form 8655 to the IRS Accounts Management Service Center, MS 6748 RAF Team, 1973 Rulon White Blvd, Ogden, UT 84404, but faxing is faster.

1. 844-249-6232: All filers (nationwide fax number for Form 8806 submissions). The IRS has required this form to be faxed rather than mailed since a July 2022 procedural update, mailing is no longer accepted.

Form 8023 has one nationwide, toll-free fax number.

1. 844-253-9765: All U.S. states and territories

The IRS asks that you send only one Form 8023 per fax, that the fax not exceed 100 pages, and that the form be signed before you fax it. No fax confirmation or receipt is issued, so keep your fax transmission log as proof of delivery.

1. 855-214-7519: Alabama, Arkansas, Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia

Stellen Sie sicher, dass Sie ein Deckblatt mit Ihren Kontaktinformationen und allen notwendigen Details beifügen, um eine ordnungsgemäße Bearbeitung Ihrer Einreichung zu ermöglichen.

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.

Fax.Plus lets you send your completed Form 911 and any supporting documentation straight from a computer, phone, or email, with a timestamped delivery confirmation for your records, useful since a case can turn on when TAS received your request.

Letter 12C is the one page in this cluster where there is no single fax number to publish, and IRS.gov says so directly: "Your Letter 0012C provides a fax number, if you want to send the information by fax. Fax your information to the fax number in the notice." The number is printed on your specific letter, not on any IRS.gov page, because it depends on which IRS processing center is handling your case.

Taxpayers have reported several different numbers on their own Letter 12C notices over time, including 855-204-5020, 855-309-9361, and 844-254-2835. These are shared here for reference only, they are not published by the IRS itself, they are not guaranteed to be current, and using the wrong one risks losing your fax and delaying your refund. Always fax to the exact number printed on the letter you received, not to a number from this list or anywhere else online.

Once you have the right number, Fax.Plus lets you send your Form 8962, Form 1095-A, and your letter's own cover page from a computer, phone, or email, with a timestamped delivery confirmation for your records, useful since the IRS itself does not confirm receipt of your fax.

Form 4506 requests a full photocopy of your tax return and must be mailed to the IRS with a $30 fee per return, there is currently no IRS fax option for Form 4506 itself. Mail to the address for the state you lived in when you filed:

1. Austin, TX (Internal Revenue Service, RAIVS Team, Stop 6716 AUSC, Austin, TX 73301): Alabama, Arizona, Arkansas, Florida, Georgia, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, a foreign country, American Samoa, Puerto Rico, Guam, the Commonwealth of the Northern Mariana Islands, the U.S. Virgin Islands, or an APO/FPO address
2. Ogden, UT (Internal Revenue Service, RAIVS Team, PO Box 9941, Mail Stop 6734, Ogden, UT 84409): Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Minnesota, Missouri, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin
3. Kansas City, MO (Internal Revenue Service, RAIVS Team, Stop 6705 S2, Kansas City, MO 64999): Alaska, California, Colorado, Hawaii, Idaho, Kansas, Michigan, Montana, Nebraska, Nevada, North Dakota, Ohio, Oregon, South Dakota, Utah, Washington, Wyoming

If you only need proof of your return's figures rather than an exact photocopy, most requesters qualify for the free Form 4506-T instead, and the IRS does accept that one by fax: 855-587-9604 (Austin), 855-298-1145 (Ogden), or 855-821-0094 (Kansas City), based on the state you lived in when you filed. Fax.Plus can send Form 4506-T to the right number directly from a computer, phone, or email, with a timestamped delivery confirmation.

1. 877-824-9110 (within the United States only, toll-free)
2. 304-707-9792 (inside or outside the United States, not toll-free)

Faxing is only available once you have paid the Form 8802 user fee through Pay.gov and entered your payment confirmation number on page 1, applicants paying by check or money order must mail their form instead. You can fax up to 10 Forms 8802, including all attachments, for a maximum of 100 pages per transmission, with a cover sheet stating the total page count.

Form 866 does not have a single published fax number the way most forms on this site do, because it is never something you fill out and send in cold. It is finalized inside an active IRS Examination or Appeals case, and the examiner or Appeals officer handling that case prepares and submits it.

That said, the IRS's own procedures do allow you to sign and return your copy by fax. Per Internal Revenue Manual 8.13.1.3.5, once you have been in contact with your assigned IRS examiner or Appeals officer and your case file documents that contact and your request to submit your signature by fax, the IRS can accept your signed Form 866 by fax for any amount of tax. There is no general public number to list here, your caseworker gives you the correct one for your case. Fax.Plus can still send your signed agreement to that number from a computer, phone, or email, with a timestamped delivery confirmation for your records.

Form 8233 is not faxed by the nonresident alien directly. After you give the completed and signed form to your withholding agent (your employer or payer), and they sign the Part IV certification, it is the withholding agent who forwards a copy to the IRS, by mail or by fax, within 5 days of accepting it.

1. 267-941-1365: All U.S. states and territories (withholding agent submissions only, maximum 25 pages per fax)

Form 637 has one nationwide fax number, the same number applies regardless of which Activity Letter you're registering for or which state you're in.

1. 855-887-7735: All U.S. states and territories

1. 844-249-8134: Automatic consent procedures, fax the signed duplicate copy of Form 3115 to the IRS National Office
2. 877-773-4950: Advance consent (non-automatic change) requests, secure fax to the IRS Chief Counsel's National Office

These are two distinct filing tracks with different rules. For automatic consent, send only one Form 3115 per fax, up to a maximum of 100 pages, no user fee required. For advance consent, a user fee is required and paid through Pay.gov, and you can also mail the request to Internal Revenue Service, Attn: CC:PA:LPD:TSS, P.O. Box 7604, Benjamin Franklin Station, Washington, DC 20044, or submit it by encrypted email. Most accounting method changes qualify for the automatic procedures.
