Can I Fax My Tax Return to the IRS?
It is tax season and you are wondering whether you can simply fax your return to the IRS instead of mailing it or filing online. The short answer is: it depends on what you are sending. Here is exactly what the IRS accepts by fax and what must go through other channels.
💡 Quick answer: Original tax returns (Form 1040) cannot be faxed — they must be e-filed or mailed. However, amended returns, audit responses, identity verification, and many other IRS documents are accepted by fax and can be sent from FaxForADollar.com for $1.00.
What the IRS Does NOT Accept by Fax
The following must be e-filed or mailed — the IRS will not accept these by fax:
- Original Form 1040 tax returns
- Original Form 1040-SR (senior tax return)
- Original Form 1040-NR (nonresident alien return)
- Payments — never fax a check or payment
⚠️ Do not fax your original tax return. The IRS will not process it. Use IRS Free File, tax software, or mail your return to the address on the instructions.

How to Find the Right IRS Fax Number
The IRS does not publish one universal fax number. The correct number depends entirely on which department is handling your case and which notice you received. Always use the fax number printed directly on your IRS notice or letter — it appears in the upper right corner or in the response instructions.
⚠️ Never use an IRS fax number from an unofficial website or forum. Always use the number on your specific notice. Using the wrong fax number means your documents go to the wrong department.
