How Identity Theft May Affect Your Tax Records

An identity thief may use a stolen Social Security number to file a tax return in order to receive an illegal refund. Identity theft can affect your current, past or future tax records.

Here are some red flags that you may be a victim of State tax identity theft:

  • You receive a State income tax refund check, but you did not file your State income tax return;
  • You attempt to electronically file your income tax return, but it is rejected because a return using your Social Security number is already filed;
  • You owe tax for a year you did not file a tax return;
  • You receive wages from an employer you did not work for.

What to do if You Believe that You are a Victim of Identity Theft

  • Complete and mail a signed copy of Form IDT-100 to:
