Identity Theft

Stopping identity theft and refund fraud is a top priority for the IRS, and the agency's work on identity theft and refund fraud continues to grow. For the 2013 filing season, the IRS has expanded these efforts to better protect taxpayers, help victims and detect refund fraud before it occurs.

By late 2012, the IRS assigned more than 3,000 IRS employees - more than double the number from 2011 - to work on identity theft-related issues. IRS employees are working to prevent refund fraud, investigate identity theft-related crimes and help taxpayers who have been victimized by identity thieves. In addition, the IRS has trained 35,000 employees who work with taxpayers to recognize identity theft indicators and help people victimized by identity theft.
