What to do if you are the victim of tax identity theft

Guidance to follow when your tax identity has been stolen


Taxpayers should familiarize themselves with the warning signs of tax identity theft and the steps they should take to minimize the effects of becoming a victim to identity theft. A common tactic that identity thieves use is to acquire a taxpayers’ social security number (SSN) and file a phony tax return using the SSN, a fake Form W-2, Wage and Tax Statement, and in some circumstances, the taxpayer’s actual name or address. The thief’s plan is to receive an electronic tax refund or a paper check from the IRS before the taxpayer ever knows that his or her identity was stolen. This greatly complicates the tax filing process for the victim and can lead to a delayed tax refund or credit; which in many cases can take as long as 18 months.

Warning signs

Taxpayers may learn they have become victims of tax identity theft if they:

  • Received a letter from the IRS Integrity and Verification unit asking them to verify their tax return information or identity
  • Received a Letter 4883C from IRS asking for them to verify their identity within 30 days through one of several methods including an online verification procedure or, in some cases, by personally appearing with identification at an IRS customer service site
  • Received a letter from the IRS informing them of a recently filed  tax return for which more information is needed before it can be processed
  • Received an IRS notice that more than one tax return was filed using a single SSN
  • Received a letter informing the taxpayer they are eligible to receive an identity protection personal identification number (IP PIN) from the IRS website
  • Received a notice of tax due, a notice of refund offset or a notice from IRS Collection for a year in which they have not yet filed a return
  • Filed their tax returns online and there is a rejection code to the e-file submission or extension request
  • Became aware of IRS records that indicate they received wages from an unknown employer
  • Delayed processing of original tax return claiming a refund by more than 6 months
  • Provided personal information to someone posing as the IRS via phone calls, e-mails, text messages, or other unofficial correspondence‒the IRS only initiates correspondence through mail and does not phone taxpayers or obtain information from them by email


Taxpayers who think they have become victims of tax identity theft should take steps to protect their identity, credit and tax filing status by:

  • Contacting the IRS Identity Protection Specialized Unit (1.800.908.4490) to confirm information relating to the warning signs above and to freeze their IRS tax account.
  • Responding immediately to any IRS notice or letter by calling the phone number provided on the notice (after verification that the phone number is a valid IRS phone number).
  • Filing Form 14039, Identity Theft Affidavit, with the IRS to begin an IRS investigation of the potential fraudulent filings using the taxpayer’s identity. Filing this form will generally result in the issuance of an IP PIN which is to be used in addition to SSNs on the tax return. If a fraudulent return has been filed by an identity thief, the taxpayer should continue to file returns and pay taxes while the case is being investigated, even if the filings must be done on paper.
  • Contacting the three major credit bureaus (Experian, Equifax and TransUnion) and request a freeze to be placed on any new credit applications using their SSN or their spouse’s SSN. The freeze can be temporarily lifted by the taxpayer, as needed. For those taxpayers who do not want to freeze their credit files, they could sign up for a reputable ID-theft-monitoring service.
  • Contacting their financial institutions and close any accounts opened without taxpayer’s permission or that have been tampered with.
  • Contacting the Federal Trade Commission’s Identity Theft Hotline (1.877.438.4338) or local law enforcement entity to report fraudulent activity so that an additional investigation can be performed.
  • Checking Social Security Administration earnings statements annually to ensure earnings are reported correctly and benefits have not been paid to an unintended recipient.
