A watchdog report says millions of Americans took education tax credits last year and they shouldn't have.
The report came out Thursday.
It says the credits were given to people who either didn't have a social security number, were in prison or unable to prove they actually attended any type of higher learning.
The Treasury Inspector General for Tax Administration, says this cost the American taxpayers more than three billion dollars.
The TIGTA provides oversight for the Internal Revenue Service, which disagrees with these findings.
