How to send IRS form by fax?

If you wish to fax your IRS form by fax, you can do so easily for free or with a paid plan by following these simple steps:

  1. Go to the FAX.PLUS Web app or use any of our other platforms (Android, iOS, …) and login to your account (You can use your current email, Google or Facebook account to sign up for free)

  2. On the app, go to the Send Fax section

  3. Enter the IRS fax number in the To field and attach the IRS form you would like to submit

  4. Click on the Send button and wait for the confirmation email.


One of the major benefits of FAX.PLUS for sending IRS forms, tax forms and legal documents, in general, is that you can print your successful fax transmission confirmation page for future references. This confirmation page is always available in your FAX.PLUS archive and will also be emailed to you right after your fax is delivered.

If you wish to go beyond just sending a free fax to IRS, you can also subscribe to one of FAX.PLUS paid plans and get a local fax number to be able to receive responses from IRS by fax.

If you want to file your taxes by fax (for Form SS-4) please find IRS fax numbers on IRS’s “Where to File Your Taxes for Form SS-4” page.

You can also find more general information on where you can file your taxes by fax (Form 1040, Form 2553, Form 4868, Form 8962, Applying for EIN, …) on IRS’s “Where to File Paper Tax Returns With or Without a Payment” page.
