Should You File Form 14039?

Form 14039 is for victims of tax-related identity theft: someone used your Social Security number or ITIN on a tax return. If the theft has not touched your taxes, this is not the form for it.

There is one important exception. If you received Letter 5071C, 4883C or 5747C, do not file Form 14039. Follow the instructions in that letter instead.

Where to Send Form 14039

There are four routes, and the IRS ranks them:

Route	Where	When to use it
Online	irs.gov/dmaf/form/f14039	The IRS's preferred route, but it cannot carry attachments
Fax	855-807-5720, cover sheet marked "Confidential"	When you want to send it with attachments, or from abroad
Mail	Department of the Treasury, Internal Revenue Service, Fresno, CA 93725	The mailing address for most filers
Your notice	The address or fax number printed on the IRS notice	When you are responding to an IRS notice

The rule: if an IRS notice started this, send Form 14039 where the notice says, including any fax number it gives. If not, fax it to 855-807-5720 with "Confidential" on the cover sheet.

How to Fax Form 14039 From Any Country

855-807-5720 is a US number. Select United States and type 8558075720: 10 digits, no leading 1, no spaces. Upload the form and any supporting pages as one PDF if you can, or up to 10 files in one fax. Our guide to faxing a US number explains the format.

People living abroad often learn about identity theft late, when a refund does not arrive or a notice reaches an old US address. Fax removes the weeks an international envelope would add. It also lets you send supporting documents with the affidavit, which the online form cannot do.

The Cover Sheet and Each Page

The IRS asks for a cover sheet marked "Confidential". Write it in large letters at the top. Below it put your full name as on your last return, the last tax year you filed, a phone number and email where you can be reached abroad, "Form 14039, Identity Theft Affidavit," and the page count.

Then the signed form, followed by any attachments in the order the form describes them. Put your name at the top of each attached page. If you are answering a notice, include a copy of the notice right after the cover sheet. Sign the form by hand, scan it flat, and check every page on your own screen before you send, because a faint signature or a cut-off line is hard to fix later.

Deadline and Your Record of the Fax

When you are answering an IRS notice, the date on that notice is your deadline. Otherwise, send the affidavit as soon as you learn your identity was used on a tax return.

When the IRS machine accepts the fax, you get a confirmation email with the destination number, the page count and the time in US Eastern Time. That is your record of exactly when it was sent. Keep it with a copy of the form and the attachments. If the IRS later asks whether you reported the theft, those three answer it.

Common Mistakes With a Faxed Form 14039

Most problems with a faxed affidavit come from a handful of small slips, all easy to avoid:

Filing it after a verification letter. If you got Letter 5071C, 4883C or 5747C, follow that letter instead. Using the general number when a notice gave its own. The notice's number wins. Leaving "Confidential" off the cover sheet. The IRS asks for it on faxed affidavits. An unsigned or half-signed form. Sign by hand before you scan. Typing 11 digits. Select United States and enter 8558075720 with no leading 1. Dark phone photos. Fax is black and white, so a shadowed photo can arrive as a grey page; a flat PDF scan is safer.

If the fax fails for any reason, the money goes back to your card automatically and you can send it again straight away.
