Frequently asked questions

The indicator helps the IRS to identify you as the valid owner of the Social Security Number (SSN) that is shown on your tax return. The indicator has no effect on your ability to file your tax return, make payments, or receive a refund.

Because you indicated you’re at risk of becoming a victim of tax-related identity theft, the indicator placed on your account will remain; unless you specifically request us to remove it.

You can call the IRS at 800-908-4490 for assistance specific to identity theft. For all other tax account related questions, visit our Online Tools and Resources page or call the IRS help desk at 800-829-1040.


Tips for next year

File your return as you normally would.
