How to fax the IRS without a fax machine

To fax the IRS without a fax machine, turn the signed form into a PDF. Send it through an online fax service or a shop counter. The fax number comes from the instructions for your form on irs.gov. The IRS has no single fax number.

This is not tax advice, and Fax for Agents is not part of the IRS. The rules below were read on irs.gov on 2026-11-10. Check the current instructions for your form before you send.

Which filings does the IRS take by fax?

Only the ones whose instructions name a fax number. These are the six cases we checked.

What you send	How the IRS takes it	IRS page
Form SS-4, to apply for an EIN	Fax or mail. Online for applicants in the United States	Instructions for Form SS-4
Form 2553, the S corporation election	Fax or mail	Instructions for Form 2553
Form 2848 or Form 8821	Fax, mail or online	Instructions for Form 2848
Form 5472 with a pro forma Form 1120, for a foreign-owned U.S. disregarded entity	Fax or mail	Instructions for Form 5472
A reply to a CP2000 notice	Upload, fax or mail	Understanding your CP2000 series notice
A Form 1040 return or Form 1040-X	E-file or mail. The pages list no fax number	Where to file paper tax returns

Where do I find the right fax number?

In the instructions for the form, under Where to file.

The form decides the number first, because each one has its own. Your state can decide it too. Forms 2553, 2848 and 8821 split the states into groups. A reply to a notice goes to the number printed on the notice.

Our page on faxing to the IRS lists the numbers for these forms and links each one to its IRS page.

Treat any list, ours included, as a pointer. Under its own chart the IRS writes "These numbers may change without notice."

What do I need before I send?

The current form from irs.gov, filled in.
A signature. Forms 2848 and 8821 sent by fax need a handwritten one.
One PDF with every page in order.
The fax number with the country code, as in +18556416935.

A phone camera is enough for the scan. Lay each page flat in good light and shoot from straight above. Check that the small print is readable, then export the pages as one PDF.

If the IRS answers by fax, as it does for Form SS-4, you also need a fax number that receives. Our post on Form SS-4 explains that part.

What are the ways to send without a fax machine?

A shop or library counter sends paper for you. Bring the signed pages and the number. Take the printed transmission report home.

An online fax service takes a PDF from the browser of a computer or a phone. You upload the file, enter the number and get a report when the call ends.

A fax API does the same from software, for a firm that sends forms as part of its work.

With Fax for Agents you send from a browser. The box under this post says how and what it costs.

How do I know the IRS got it?

You know the pages were transmitted. You do not know they were processed until the IRS answers.

A transmission report or receipt records what the receiving machine accepted. It names the number, the pages and the time. Keep it with a copy of what you sent.

The IRS does not confirm a fax on the one page where it speaks to this. Its page on faxing Form 8023 says "The IRS will not provide a fax confirmation of receipt of Form 8023".

Its audits page says to "always request confirmation that the IRS has received your response".

Two IRS pages do tell you something. The Document Upload Tool confirms that the IRS received a reply to a notice. The processing status page shows how far along the IRS is with each kind of form.

What if the fax does not go through?

A busy signal means the line is taken. Wait and send again. If it fails twice, compare the number with the IRS page once more.

Find out what your service does before you resend. Fax for Agents tries a busy line or no answer again after 60 seconds, 3 attempts in all, as of 2026-11-10. A fax that ends failed costs nothing.

Do not resend after a success. The IRS asks people who already sent Form 2848 or 8821 not to submit a duplicate.

Is it safe to fax tax documents?

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

So read them before you upload. Look for how long the service keeps your file, whether you can delete it at once and who else handles it.

At Fax for Agents a document is deleted after 30 days by default, as of 2026-10-28. The send dialog has a box that deletes it when the fax ends. The carrier receives the pages to place the call. The service is not a HIPAA service. The fax to the IRS page has the full list.

A fax call is not encrypted on the phone line, whoever sends it. Check the number twice, because a wrong digit sends your form to a stranger.

Send it with Fax for Agents

One fax paid by card costs $2.49 for up to 5 pages to the United States and Canada. Each extra page costs $0.49. One fax takes 20 pages at most. A cover sheet with your name and email address is included and not counted. Your card is charged only after the carrier confirms pages. If part of the document arrives, you pay for the confirmed pages by the same rule, so 1 to 5 confirmed pages cost $2.49.

Prices as of 2026-11-12, from the rate table on the pricing page.

A filing longer than 20 pages

It goes through the prepaid wallet, which is also the way to send when a one-time order is refused.

Sign in to the dashboard, top up the prepaid wallet and send from your browser. A page to the United States or Canada costs $0.039 as of 2026-10-28. The smallest top-up is $10.

A fax of 6 pages costs $0.234. So for one fax you pay $10 up front and use a small part of it. The rest stays in your wallet, and we refund unspent balance when you ask.

One document can have 200 pages and 25 MiB. From the wallet a cover sheet counts as a page.

A busy line or no answer is tried again after 60 seconds, 3 attempts in all.

A fax that ends failed costs nothing. From the wallet a partial one costs each page the carrier confirmed.

The receipt is a record of transmission. It is not an acknowledgement from the tax agency.

The prices and limits are in facts.json with their dates and methods. The steps, the receipt and how documents are handled are on the IRS fax page.

Questions

Can I fax the IRS from my phone?

Yes. Photograph or scan each signed page with the phone. Export the pages as one PDF and upload it to an online fax service in the phone's browser. Check before you send that every page is upright and that small print is readable. Enter the IRS number with the country code, as in +18556416935 for the Form SS-4 line read on 2026-11-10. Save the receipt to the phone when the fax ends.

Is there an IRS fax number for Form 1040?

The IRS pages we read on 2026-11-10 list none. The page on where to file paper returns gives a mailing address for each state and points to e-file. The Form 1040-X instructions say to file electronically or mail the form. If a notice or an IRS employee gave you a fax number for a return, that number is for your case. A fax number taken from another form is the wrong place for a return.

How long does the IRS take to process a faxed form?

It depends on the form, and the IRS publishes the current wait. On 2026-11-10 its processing status page, dated 2026-11-06, showed a faxed Form SS-4 as processed 4 business days after receipt. It showed Forms 2848 and 8821 as processed 3 business days after receipt. For Form 2553 the instructions say a determination should come within 60 days in most cases. Those figures move, so open the status page on the day you send.
