In the four years since its inception, the Indiana Department of Revenue’s (DOR) Identity Theft and Fraud Prevention Program has stopped over $110 million in attempted identity theft and tax fraud. A continued decrease in fraud dollars is expected for 2018 through the use of DOR’s three-step authentication to detect tax fraud and the agency’s collaboration with other states to share fraud data patterns. More information about stopping ID theft can be found on DOR’s website at Information about the tax fraud prevention program and how to report tax fraud can be found on DOR’s website at For more information, customers may visit the DOR website at or call DOR Customer Service at 317-232-2240, Monday through Friday, 8 a.m. – 4:30 p.m. EST.
