IRS Fax Number for Individual Tax Returns — Send Your Forms Now

The IRS won't take an original Form 1040 by fax, but plenty of individual tax documents do move that way once you know which line to use. Amended returns on Form 1040-X, transcript requests on Form 4506-T, identity theft affidavits on Form 14039, installment requests on Form 9465, and Power of Attorney on Form 2848 each route to their own fax number. Because the destination depends on the form, confirm the current number on IRS.gov for whichever document you're sending before you transmit.

What You Can Fax to IRS - Individual Tax Returns

  • Form 1040-X amended returns
  • Form 4506-T transcript requests
  • Identity verification documents (Form 14039)
  • Installment agreement requests (Form 9465)
  • Power of Attorney (Form 2848)
Tip: Write your SSN or TIN on every page so a multi-page submission stays attached to your account. Lead with a cover sheet that names the exact department or unit handling your form, since the IRS sorts incoming faxes by purpose. Faxed individual documents can take four to six weeks to post, so keep your confirmation receipt as proof of the filing date and follow up if you hear nothing after a couple of weeks.

Faxing to IRS - Individual Tax Returns — FAQ

No — original Form 1040 returns can't be filed by fax. The IRS does accept faxed amended returns on Form 1040-X, transcript requests on Form 4506-T, and several other individual forms. Each goes to a different number, so check the form's instructions for the right line.

Commonly faxed forms include Form 4506-T for transcripts, Form 2848 for Power of Attorney, Form 8821 for tax information authorization, Form 14039 for identity theft, and Form 9465 for installment agreements. The fax number is tied to the form and sometimes to your location, so verify it on IRS.gov.

Send FAX Mail returns a delivery confirmation with a timestamp, which serves as your proof of submission. If you don't see any acknowledgment from the IRS after about two weeks, call to confirm the document was logged.

Faxed pages can arrive out of order or get separated during processing, and the SSN or TIN is what ties each sheet back to your individual account. Without it, a stray page may not be matched to your file.
