Can you fax your tax return to the IRS?

Before you fax

• With no notice, file your return by mail or e-file. The IRS lists fax for some forms (such as Form SS-4 or Form 2848), not for original returns.
• CP518 and CP518I: send Form 15103, Form 1040 Return Delinquency, with the return if you are filing one, to the fax number in the notice.
• If you are only sending Form 15103 to explain why you don't have to file, you can also submit it online with an IRS Online Account.
• CP518B and CP259 (businesses): fax your documents to 855-800-5944, or use the envelope that came with the notice.
• The IRS asks you to understand the fax service's privacy and security policies before sending.

How to send it without a fax machine

1. Find the fax number on your notice (855-800-5944 for a CP518B).
2. Put the notice's response page or Form 15103 first, then the return or documents.
3. Scan or photograph every page, enter the number and add the pages.
4. Send, and keep the delivery receipt as proof of when you replied.
