Form 14039: Identity Theft Affidavit
Form 14039, Identity Theft Affidavit, is the IRS form for victims of identity theft. The form covers three situations: someone used the victim's information to fraudulently file a federal tax return, the victim or a dependent was fraudulently or incorrectly claimed as a dependent, or an SSN or ITIN was fraudulently used for employment.
The victim can submit it, or someone can submit it on the victim's behalf: a surviving spouse, a court-appointed or certified personal representative, a relative of a decedent, a conservator, a person authorized on Form 2848, or a parent or guardian of a dependent. The form says Sections A to E are required, and Section F is required when completing it on someone else's behalf. It also says not to use the form if one was already filed for the same incident.
The form says it can also be completed online at https://www.irs.gov/dmaf/form/f14039, which it calls the preferred method. You can fill out the PDF free in your browser on this page and download it without an account.
