How to Fax Forms to the IRS

IRS Fax Numbers

The IRS uses different fax numbers depending on the form you're submitting and your location. The correct fax number is listed in the instructions for each specific form on IRS.gov. Always check the form instructions before sending, as fax numbers can change.

• Form SS-4 — Application for Employer Identification Number (EIN)
• Form 8821 — Tax Information Authorization
• Form 2848 — Power of Attorney and Declaration of Representative
• Determination letter requests — Various applications for tax-exempt status and rulings

Not all forms can be faxed. Always check the form instructions on IRS.gov to confirm whether fax submission is accepted.
