Identity Theft Affidavit

identity theft.fwIf you suspect or there is proof that your social security number in combination with other personal information was used to file a tax return, get a job, or apply for a loan, you may have been a victim of identity theft.

In that case you should contact the IRS immediately and explain your predicament. Act swiftly and take another step by filing Identity Theft Affidavit or Form 14039. By submitting this form, you let the IRS know that you are a victim or a potential victim of identity theft and would like your account to be scrutinized for any suspicious activity.


Form 14039 – Structure

The main section of the form is the one where you let the IRS know that you either:

  • (Box 1) Are a victim of identity theft and it is affecting your federal tax records – this may be your selection if your intent to file electronically failed because someone had already used your Social Security or Individual Taxpayer Identification Number to file taxes, or if you received a letter from the IRS stating that someone had already used those numbers to file taxes
  • (Box 2) Experienced an event involving your personal information that may affect your tax records in the future – you may choose this option if your personal information was used to obtain credit; no identity theft violation has occurred but you lost your documents or were a victim of a robbery, or any event that puts your personal information in the hands of others that may misuse it in the future

Regardless of which situation you select, you have to provide explanation of what happened or what makes you believe you may be a victim of identity theft in the future.

You then have to provide personal information accompanied by copies of documents verifying your identity. The IRS allows the following documents to prove identity:

  • Passport
  • Driver’s license
  • Social Security Card
  • Other valid U.S. Federal or State issued id

Additionally, if you are submitting the form on behalf of someone else, you have to complete Section E – Representative Information where you indicate the reason for doing so.

What to do with the form

  • Form 14039 can be either mailed of faxed. If you still haven’t filed you return, include the form with your return and all supporting documents and mail it to where you typically mail tax return. If you have already filed your taxes, send the form and all documents to where you typically file.
  • If you are responding to a letter from the IRS, send the requested documents to the address provided or fax it to the number listed.
  • If you checked Box 2 on the form, fax it to 855 807 5720 or mail it to Internal Revenue Service, PO Box 9039, Andover MA 10810-0939
