The IRS says it paid whistleblowers a total of $53 million last year for turning in tax cheats.

In an annual report to Congress, the agency said Friday it paid out 122 awards. That’s an average award of nearly $435,000.

The tips led the IRS to collect more than $367 million in taxes, interest and penalties.

The report says the IRS received 9,268 whistleblower claims last year, up slightly from 2012.
