How to fax the IRS from your phone
The IRS still accepts faxes in specific situations. For example, some notices tell you to fax your response, and the instructions for some forms list fax numbers for submitting them. If you've been told to fax the IRS, you can do it from your phone instead of finding a fax machine. This fax-from-phone.com guide explains how to find the correct number, prepare your pages and send them securely with FaxToFax.com.
Get Started NowFind the correct IRS fax number
The IRS uses many different fax numbers, depending on the form, the department, and sometimes the state you live in. There's no single IRS fax number for everything. Use the number that appears on the notice or letter you received, or in the current instructions for the form you're filing. If neither gives one, the IRS may not accept that document by fax.
Never use a number from a third-party website or a message you didn't expect. If something claiming to be from the IRS asks you to fax personal information, verify it through IRS.gov or the phone number on an official notice first.
Consider the alternatives
The IRS has expanded online options, including an online account and, for some notices, a document upload tool linked in the notice itself. If your notice offers an upload option, that may be faster. Fax remains a good choice when it's the method the notice gives, or when you need a clear record of when you responded.
If you work with a tax professional, ask them before you respond. They may already be handling the notice, and some authorization forms, such as those that let a representative deal with the IRS for you, have their own submission options listed in the form instructions. The guides on fax-from-phone.com cover the sending side, but your tax adviser is the right person for what to send.
Prepare your documents
- Put a copy of the IRS notice or letter on top, or at least the page showing the notice number and your details.
- Add your response or completed form, signed and dated where required.
- Include supporting documents in the order the notice asks for them.
- Write your name and taxpayer ID, or the last four digits if the notice says that's enough, on each page in case pages get separated.
- Scan everything into one PDF with your phone's document scanner.
Send the fax
- Open your phone's browser and sign in at FaxToFax.com with your email and one-time code.
- Create a new fax and attach your PDF.
- Add a cover page with your name, the notice number, the tax year, a daytime phone number and the total page count.
- Enter the IRS fax number from your notice or form instructions and confirm it.
- Send, then keep the page open until the status reads Delivered.
Keep proof and follow up
IRS notices often include a response date. Each delivered fax has a time-stamped delivery receipt saved with it, which shows exactly when your pages arrived. Save that receipt with a copy of what you sent. If a fax fails because the line is busy, which is common with high-volume IRS numbers, no pages are used and you can try again.
Processing can take weeks, so allow the time the notice gives before you call. Have your notice, your copy of the fax and the delivery receipt ready. Your FaxToFax audit log records every send and download, which helps if you need to show when you handled the matter.
How to Fax the IRS from Your Phone: questions
Is there one fax number for the IRS?
No. Fax numbers depend on the form, the department and sometimes your location. Use the number on your notice or in the form's current instructions.
Can I fax a tax return to the IRS?
Generally, regular returns are e-filed or mailed. Only fax a return or form when the IRS instructions or a notice tell you to.
What if the IRS fax line is always busy?
Failed faxes use no pages, so you can retry. You can also schedule the fax to send at a quieter time, such as early morning.
How do I prove I responded on time?
Keep the time-stamped delivery receipt saved with your delivered fax, along with a copy of the pages you sent.
