How to Fax Documents to the IRS (Complete Guide)

Can You Fax Documents to the IRS?

Yes. The IRS accepts faxed documents for many common forms and requests. In fact, faxing is often the fastest way to respond to an IRS notice or submit time-sensitive paperwork. While the IRS has been slowly modernizing, fax remains one of their primary methods for receiving documents from taxpayers and tax professionals.

Not every form can be faxed, but many of the most frequently needed ones can. Knowing which forms the IRS accepts by fax and where to send them can save you days compared to mailing documents.

Common IRS Forms You Can Fax

Here are some of the most commonly faxed IRS forms and their associated fax numbers:

Form 4506-T (Request for Transcript of Tax Return) Used to request copies of past tax returns. Mortgage lenders, landlords, and financial institutions frequently require this form. Fax to: 855-298-1145 (for individual requests).

Form 2848 (Power of Attorney and Declaration of Representative) Authorizes a tax professional to represent you before the IRS. Fax to: 855-214-7522.

Form 8821 (Tax Information Authorization) Allows a third party to receive your tax information without representing you. Fax to: 855-214-7522.

Form 8508 (Request for Waiver from Filing Information Returns Electronically) Used by businesses that need a waiver from electronic filing requirements. Fax to the number specified in the form instructions, which varies by filing type.

Identity verification documents. If you receive an IRS letter requesting identity verification (such as Letter 5071C or 4883C), you may be able to fax supporting documents like a copy of your ID. The fax number will be listed in the letter.

Always check the latest IRS instructions for each form, as fax numbers can change.

Tips for Faxing to the IRS

The IRS processes a massive volume of faxes. Follow these tips to make sure yours gets handled correctly:

Include a cover page. List your name, Social Security number (or EIN for businesses), the form name and number, your phone number, and the total number of pages. The IRS uses this information to route your fax to the right department.
Write legibly. If any part of your form is handwritten, make sure it is clearly readable. Illegible faxes can be rejected or cause processing errors.
Keep it to the point. Only send the specific form or documents requested. Sending extra paperwork slows down processing.
Save your confirmation. After sending, keep the delivery confirmation as proof that you submitted your documents. If the IRS claims they did not receive your fax, this confirmation is your evidence.
Fax during off-peak hours. IRS fax lines can be busy, especially around tax deadlines. Try sending early in the morning or later in the evening for a better chance of getting through on the first attempt.
