You do not need a fax machine to send documents to the IRS. An online fax app turns a photo or PDF into a fax from your phone or computer, and our top pick is Faxend, the fastest way to fax the IRS from an iPhone. Below I walk through the exact steps, how to confirm the right IRS number, and how to keep sensitive tax documents secure.
The Short Answer: No Machine Required
You can fax the IRS without owning a fax machine. An online fax service sends your document over the internet to the IRS fax line, so the receiving end still gets a normal fax while you never touch a physical machine.
The tool you use matters. Our top pick is Faxend, the fastest way to send a fax from an iPhone. You photograph or attach the form, enter the IRS fax number, and the app handles the transmission. It is free to download, with per-fax or plan pricing when you send.
If you are on Android, a desktop, or you prefer email, there are solid options too. I cover those below so you can match the method to the device you actually have in front of you.
Find the Correct IRS Fax Number First
Before you send anything, confirm the fax number. The IRS uses different fax numbers for different forms and situations, and those numbers change. A number that worked last year may route somewhere else today.
Get the number straight from the source. Look up the official page for your specific form on irs.gov, or check the instructions that came with the form. Do not trust a fax number you found on a random forum or an old screenshot.
If you are not sure which number applies to your form, our guide on IRS fax numbers and how to find the right one walks through where each one lives on the IRS site. When in doubt, the form instructions are the authority.
Write down the exact form number and the date you confirmed the fax line. IRS fax numbers are tied to specific forms and locations, so a quick note now saves a misfire later.

Other Ways to Fax the IRS Without a Machine
Not everyone wants an app. Here are the main alternatives, ranked with Faxend at the top since it is the quickest route from a phone.
| Method | Best for | Notes |
|---|---|---|
| Faxend | iPhone users sending a form fast | Our top pick. Photo or PDF to fax in a couple of taps. Free to download, pay per fax or by plan. |
| Web-based fax service | Sending from a laptop browser | No install. Upload the PDF and send from any computer. |
| Email-to-fax | People who live in their inbox | Attach the form to an email addressed to a fax gateway. |
| Android fax app | Android phone owners | Same idea as Faxend, on a different platform. |

Each of these reaches the same IRS fax line. The difference is the device you start from and how much setup you want. For most people sending a single form, the phone app is the shortest path.
What to Put on Your IRS Fax Cover Sheet
A clear cover sheet helps the IRS route your fax to the right place. Include your full name, your taxpayer identification or Social Security number, the form number you are sending, the total page count, and a daytime phone number.
Keep it simple and legible. If you are responding to an IRS notice, add the notice number and date so the agent can match your fax to your case quickly.
The page count line matters more than people expect. If the IRS receives four pages when your cover sheet says five, they know a page dropped and can ask you to resend.
Keep Your Tax Documents Secure
Tax forms carry sensitive data, so the service you choose should protect it. Look for encryption in transit, a clear privacy policy, and a company that does not keep your documents longer than needed.
Faxing is often preferred for IRS submissions because a fax travels point to point rather than sitting on mail servers. That said, the app or website you send from still handles your file, so pick one that states how it stores and deletes documents.
Avoid free tools that stamp watermarks or advertising onto your pages. For a form headed to the IRS, a clean, unbranded transmission is worth the small per-fax cost.
Common Forms People Fax to the IRS
Some IRS forms are routinely accepted by fax. The ones I see people send most often include:
- Form 2848, Power of Attorney and Declaration of Representative
- Form SS-4 to request an Employer Identification Number
- Form 2553 for an S corporation election
- Forms 433-D and 433-F to set up a payment plan
- Written responses to IRS notices that specifically request a faxed reply
Always confirm on irs.gov that your form can be faxed and which number to use. Not every form is accepted by fax, and sending to the wrong line can delay processing. For more step by step walkthroughs, browse our how-to guides.
