Fax IRS documents online
How to fax IRS forms & responses online
If the IRS instructions for your form or notice say faxing is allowed, you can send the documents online with FaxyFox — no fax machine required. Upload your completed pages, enter the IRS fax number from the official instructions, and we send them through the fax network.
Before you send: IRS fax numbers and filing methods vary by form, by notice, and sometimes by location. Always confirm the current fax instructions on IRS.gov or use the fax number printed on your IRS notice.
Does the IRS accept documents by fax?
Yes — for certain forms, authorizations, notices and workflows. Fax is not a universal filing method, so the instructions for the specific document always control.
The IRS currently provides fax submission options for Form 2553, and for Forms 2848 and 8821 in applicable situations. Some IRS notices also tell recipients they may fax a response to the number printed on the notice.
The rule is simple: if the current IRS instructions or your notice say “fax”, FaxyFox can send it.
First, check the instructions for your form or notice
Before uploading anything, confirm that faxing is actually permitted and identify the exact destination number.
If you are sending a form
The current instructions for that form
Its “Where to File” section
Whether the destination depends on your location
Whether a particular signature type is required
If you are answering a notice
The fax number printed on the notice
The response deadline
The documents the notice asks you to include
Whether another submission method is offered
Do not guess an IRS fax number, and do not reuse one from an unrelated form.
How to fax an IRS document online
STEP 1
Prepare the document
Complete the form or response, with every required page, signature and supporting document.
STEP 2
Upload your pages
Add the PDF or images to FaxyFox and put them in the order they should be sent.
STEP 3
Enter the IRS fax number
Copy it from the current instructions or from the notice you received.
STEP 4
Send and track it
Submit the fax and watch its delivery status from your account.
Check the signature rules before faxing
Some IRS forms have signature requirements that depend on how they are submitted.
For example, the IRS currently says Forms 2848 and 8821 sent by fax or mail must carry a handwritten “wet ink” signature. Electronic signatures are handled through the IRS's own online submission process instead. This does not apply to every IRS fax — check the instructions for yours.
Where do I find the correct IRS fax number?
The right number depends on what you are sending. There are three places to look.
The form instructions
Some forms list fax destinations in their official filing instructions.
Your IRS notice
If the IRS mailed you a notice that allows a fax response, use the number shown on it.
IRS.gov
When in doubt, check the current IRS page for your form or notice before sending.
Do not use an IRS fax number found on an old website, a forum post, or an unrelated document. These change, and a tax document sent to the wrong number is a problem you cannot take back.
Examples of IRS documents that may be faxed
Fax availability depends on the current instructions, but these are IRS workflows that currently include fax submission options.
Form 2553
Election by a Small Business Corporation
The IRS currently provides fax destinations for Form 2553, with the correct IRS center determined by the corporation's location.
Form 2848
Power of Attorney and Declaration of Representative
The IRS currently provides fax, mail and online submission options, depending on the workflow.
Form 8821
Tax Information Authorization
Form 8821 can also be submitted using IRS-approved methods that currently include fax in applicable situations.
Notice responses
Some IRS notices
Certain IRS notices specifically tell recipients they may fax the requested information, including through an online fax service.
These are examples, not a complete list. Always use the current instructions for the specific document you are sending.
Can I fax my tax return to the IRS?
Do not assume a normal tax return can be faxed just because the IRS accepts fax for some documents.
Tax returns generally have their own filing methods, such as electronic filing or mail. Only use fax when the IRS instructions or notice for your specific situation explicitly allow it.
Get all the pages ready before you send
IRS submissions often run to more than one page: the main form, a signature page, supporting documents, sometimes a copy of the notice itself. FaxyFox lets you upload PDFs and supported images and arrange the pages before sending.

Sending the IRS fax from your phone?
FaxyFox works straight from a mobile browser. Upload the completed PDF or a scan, enter the fax number, and send.
Keep track of whether the fax was delivered
FaxyFox shows the delivery status of every fax you send. For tax paperwork it is worth keeping your own record of when you sent the documents and what the result was.
A delivered status means the fax transmission completed. It does not mean the IRS has reviewed, accepted or processed the documents.
Do not leave it until the last minute
Fax transmission takes several minutes, and a busy destination or a retry can make it take longer. If your form or notice has a deadline, leave enough time to confirm the result rather than only to press send.
If timing is legally important, follow the IRS instructions for that form or notice and consult a qualified tax professional when you need to.
Treat tax documents as sensitive
Tax paperwork carries Social Security numbers, employer identification numbers, addresses and financial details.
Double-check the destination fax number before sending, and only send documents that the IRS or the appropriate recipient has actually asked for. FaxyFox uses secure document handling and account access, but the destination number is yours to verify.

Some IRS notices allow fax responses. If yours does, use the fax number and instructions printed on that notice.
Some IRS guidance explicitly states that a permitted fax response may be sent using either a fax machine or an online fax service. The instructions for your specific form or notice still control.
Use the number in the current official filing instructions, or the number printed on your IRS notice. Do not guess, and do not reuse a number from an unrelated form.
Follow the instructions for the form or notice. Where the IRS does not prohibit one, a brief cover page can help identify the recipient, sender and purpose — but it never replaces required forms or information.
