Answers to common questions

What effect does the Identity Theft Indicator have on my account?

The indicator has no effect on your ability to file your tax return, make payments, or receive a refund.

How long does the indicator remain on my account?

The indicator will remain on your tax account to protect it because you were a victim of identity theft, unless you specifically request that we remove it.

What happens if someone else uses my SSN to file a fraudulent tax return?

The indicator we placed on your account will alert us to perform research to make sure a tax return filed with your SSN is valid. If we find the tax return to be invalid, we won't process it.
