You don’t need to be in the US to fax the IRS. Foreign-owned entities filing Form 5472 and founders applying for an EIN with Form SS-4 are among our most common senders.

Common questions
Can I really fax to the IRS for free?
Yes. FaxTerra gives you 10 free pages a month, enough for most IRS forms. If your document is longer, credit packs start at $1.99 for 10 pages. No subscription required just to send.
How long does the IRS take to fax back an EIN?
For a faxed Form SS-4, the IRS's published target is 4 business days. The typical wait we measure across real filings is about 16 days. For an application by mail, the IRS quotes approximately 4 weeks.
Will the IRS know my fax came from an online service?
Your fax arrives at the IRS as you sent it, with no ads or watermark. If you subscribe, your own fax number appears as the sender. To the IRS it is a normal fax.
What if the IRS needs to fax something back to me?
Form SS-4 is the IRS filing that gets a fax back. The IRS faxes your EIN to the number in the form's "Applicant's fax number" field. Free sends go out from a shared number, which can't receive faxes for you. A FaxTerra subscription ($4.99/month) gives you a fax number of your own for that field. When the IRS faxes back, you get an email and a push notification in the mobile app, and the fax is ready to view or download as a PDF.
Which IRS forms can I fax?
The IRS accepts many forms by fax, including Form SS-4 (EIN application), Form 5472, Form 2848 (power of attorney), Form 8821 (tax information authorization), and Form 911 (Taxpayer Advocate). Each has its own fax number, listed in the directory above.
I need to fax Form 5472. Can I e-file it instead?
No. A foreign-owned single-member LLC cannot e-file Form 5472. The IRS takes it by mail or fax, and a fax gives you a delivery confirmation receipt. The fax number for Form 5472 is (855) 887-7737.
Is it secure to fax tax documents online?
Yes. Your documents are encrypted in transit and encrypted at rest while stored.

Excellent · TrustScore 4.7I needed to fax something and the closest fax machine is about a 30 min drive away. I looked up if there was a way to get the fax done without having to drive and tried out FaxTerra. The website and experience were both logical and easy.
