If you need to submit IRS documents quickly and securely, you may be asking: what is the fax number for the IRS? While the IRS has moved toward electronic filing for many services, faxing is still allowed for certain forms, especially EIN applications, SS-4 forms, and international tax matters.
This article covers how to find the correct fax number for the IRS based on the form, purpose, and department you’re working with.
Can You Fax Documents to the IRS?
Yes, but only certain forms are accepted via fax, and they must be sent to the correct IRS department. Some of the most commonly faxed forms include:
- Form SS-4 (EIN application)

- Form 147C (EIN verification requests)
- Form 2848 (Power of Attorney)
- Responses to IRS notices
Always verify the correct fax number on the IRS website or the instructions for the specific form you are submitting.
