Fax a form to the IRS from your browser

The IRS has no single fax number. Each form has its own, and several depend on your state. The table below lists them as read on irs.gov on 2026-11-10. You can send the fax from your browser with Fax for Agents and keep a receipt.

This page is not tax or legal advice, and Fax for Agents is not part of the IRS. Open the linked IRS page and the current instructions for your form before you send.

How do I reply to an IRS notice by fax?

Use the fax number printed on the notice or letter. No table replaces it.

For a CP2000 notice the IRS gives three ways to reply. It calls its upload tool "the fastest way to send us your reply". Fax and mail are the other two. The fax number depends on the location named on the top left side of the notice.

The IRS Document Upload Tool takes scans and photos of a reply, and the IRS confirms that it received them. A fax receipt cannot do that. The IRS says not to send tax returns through the tool.

For an audit by mail, the IRS audits page says to fax a request for more time to the number on its letter.

What does the IRS not take by fax?

The IRS pages we read give no fax number for a Form 1040 return. The same holds for an amended return. The IRS page Where to file paper tax returns with or without a payment lists mailing addresses by state. The Form 1040-X instructions say to file electronically or mail the form.

The IRS page for Form 3911, the refund trace, lists that form's own fax numbers by state. It says to send nothing but a Form 3911 to them.

How do I send the fax?

  1. 01 / Get the form and its fax number

    Download the current form and its instructions from irs.gov. Find the fax number under Where to file. Compare it with the table on this page.

  2. 02 / Fill it in and sign by hand

    Complete the form and sign it in ink where it asks for a signature. Forms 2848 and 8821 sent by fax need a handwritten signature.

  3. 03 / Make one PDF

    Scan every page into one PDF, in the order the IRS expects. Check that each page is upright and readable. Then count the pages.

  4. 04 / Upload and enter the number

    Open the send page and upload the PDF. Enter the IRS number as +1 and the ten digits. Add your name and your email address.

  5. 05 / Pay by card and confirm

    The page shows the price before you pay. Pay by card. Then confirm the send from the mail we send to your address.

  6. 06 / Keep the receipt

    When the fax ends, download the receipt as a PDF. Keep it with a copy of the pages you sent.

  7. 07 / Follow up with the IRS

    The receipt shows that the pages were transmitted. Only the IRS can tell you the form was processed. The instructions for the form say when to follow up.

Write the number with the country code and no spaces. The Form SS-4 number 855-641-6935 becomes +18556416935.

Uploads take PDF, PNG, JPG and TIFF files. A Word or Excel file has to be saved as a PDF first.

Do I need a cover sheet?

The instructions we read for Forms SS-4, 2553, 2848, 8821 and 5472 do not ask for a cover sheet. A notice or an IRS employee can ask for one, and then their request is the rule.

On its page about faxing Form 8023 the IRS describes a cover sheet. It lists the subject, the sender's name, title, phone number and address, the taxpayer's name, the date and the page count with the cover. It adds "Do not include sensitive information on the cover sheet, such as Employer Identification Number or Social Security number".

Fax for Agents has no cover sheet file to download. The send dialog in the dashboard adds a cover page when you fill in Subject or Message. It prints the destination number, the date, the page count, your subject and your message. From the wallet it counts as one page.

That cover page does not print your name. Write your name and a phone number in the message. The Sender name field of the dialog puts a name in the fax header beside the sending number.

A fax paid by card always carries a cover sheet with your name and your email address. It is included in the price and not counted as a page.

What does the receipt prove?

The receipt proves that the carrier reported your pages as sent to that number at that time. It does not prove that the IRS processed, accepted or read them.

It holds the fax number, the pages sent out of the pages billed, and the start and end times. It also holds the carrier's fax id, status and call duration, the SHA-256 hash of your document and the amount charged. You can download it as a one-page PDF from the fax's page in the dashboard.

The IRS states its side on its Form 8023 fax page. It says "The IRS will not provide a fax confirmation of receipt of Form 8023". It tells filers to keep their fax transmission log as their confirmation.

For Form 2553 the instructions list what the IRS accepts as proof of filing. A fax log is not on that list. They say to call 800-829-4933 when no answer has come within 2 months of the date you faxed.

What happens when the IRS line is busy?

A busy line or no answer is tried again after 60 seconds, 3 attempts in all. If none connects, the fax ends failed and nothing is charged.

That covers a short busy spell. It does not cover a line that stays busy for an hour. A failed fax is not sent again on its own, so check the result and send again later.

A fax that stops partway ends partial. You pay for the pages the carrier confirmed and nothing is sent again on its own. Read the receipt before you resend, so the IRS does not get the same pages twice.

The retry figures were read from the code on 2026-11-10 and are in facts.json.

How are my tax documents handled?

The IRS gives this advice on its CP2000 page. It reads "Protect your information: If you use an online fax service, understand its privacy and security policies". Here are ours, in short.

Fax for Agents is not a HIPAA service and holds no security certification. The privacy policy says what is kept and for how long.

A fax paid by card has a few rules of its own. They are on the send a fax page and in the privacy policy.

The retention period is the default as of 2026-10-28, from facts.json.

Questions

Can I fax my tax return to the IRS?

The IRS pages we read on 2026-11-10 give no fax number for a Form 1040 return. The page on paper returns lists a mailing address for each state and points to e-file. The Form 1040-X instructions say to file electronically or mail the form. A fax is for the forms and replies whose own instructions name a fax number. If an IRS employee or a notice gave you a fax number, use that one.

Does the IRS confirm that it received my fax?

The IRS says no on the one page where it answers this. Its page on faxing Form 8023 says the IRS will not provide a fax confirmation of receipt. It tells filers to keep their fax transmission log. Our receipt is that log. It records the number, the pages, the time and the carrier's report. It does not show that the IRS processed the form. For that, follow the form's instructions or call the IRS.

Can I sign the form on screen and then fax it?

Not for Forms 2848 and 8821. Their instructions say you must handwrite your signature if you file by mail or by fax. A typed or electronic signature is valid only when the form is submitted online. Print the form, sign it in ink and scan it. For another form, read the signature section of its instructions. We do not check signatures. We send the pages as you uploaded them.

How many pages can I send in one fax?

One fax paid by card takes up to 20 pages. A longer filing goes through the prepaid wallet, where one document can have 200 pages and 25 MiB. Split anything longer into two faxes and say so on the first page of each. A wallet page costs $0.039 as of 2026-10-28. Count your pages before you choose, because the IRS instructions for some forms ask for attachments.

Can the IRS fax its answer back to me?

Only to a fax number that receives. The Form SS-4 instructions ask for your fax number so the IRS can fax the EIN back. The number in our fax header is a shared sending number and takes no replies for you. To receive, rent a number in the dashboard from the prepaid wallet. It costs $2 a month plus $0.019 per received page, as of 2026-10-28. Write that number on the form. The reply lands in your private inbox as a PDF.

Is Fax for Agents approved or recommended by the IRS?

No. Fax for Agents is a private fax service made by JSB Holdings LLC. It has no connection to the IRS, and the IRS has not approved or recommended it. Nothing on this page is tax or legal advice. The fax numbers and rules here were read on irs.gov on 2026-11-10 and each one links to its page. Check that page and the current instructions for your form before you send.
