There is no single IRS fax number. Each form has its own fax number, and a few forms route by state or region. Below is the complete, verified directory of IRS fax numbers for the forms the IRS accepts by fax — with what each form is for, the fax number(s), and processing notes. Numbers are matched to each form's official IRS source.
Last verified: June 8, 2026 against official IRS form instructions. Several forms — including 2553, 2848, 8821, 3911, and 4506-T — route to different fax numbers by state, so always confirm the number that matches your state before sending.

How to Fax an IRS Form
- Confirm the form accepts fax. Use the table above. Forms like 1040-X, 4868, 8822, and 8832 do not have a fax number and must be e-filed or mailed.
- Find the right number. Some forms (SS-4, 4506-T) route by region or whether you're inside the U.S. — pick the number that matches your situation.
- Complete and sign the form. Unsigned authorization forms (2848, 8821) are rejected. For SS-4 Fax-TIN, include a return fax number so the IRS can fax your EIN back.
- Add a cover sheet. Note the form name and your callback number. You can build one free with the fax cover sheet generator.
- Send and keep the confirmation. Fax it and save the transmission receipt as proof of the date you submitted.
