Taxpayers may be asked to take identity quiz

Group mobilizes Wisconsin Teamsters against pension cuts

Wisconsin revenue officials say some taxpayers may be asked to take a short quiz to verify their identity.

The Wisconsin Department of Revenue estimates the four-question quiz launched last year helped to save nearly $50 million in fraudulent or inappropriately filed claims.

The department will review more than 60,000 returns filed over the weekend and earlier this week.

Taxpayers are selected for review based on analytics. Those selected have 20 days to take the quiz online or by phone. If they fail to answer the questions correctly, they will be offered the chance to take it again. After a second failure, taxpayers will be obligated to mail documentation to the Department of Revenue to prove their identity.
