Nearly 1,000 former medical residents and a Cincinnati hospital will split $20 million in refunds from the Internal Revenue Service.
The IRS says stipends paid to former residents from 1997 to 2005 weren't subject to Social Security taxes because the residents were students.
An attorney for University Hospital in Cincinnati says the refunds will total $20 million. The former residents will get half.
Students are usually exempt from taxes that fund Social Security and Medicare. The IRS conceded earlier this year that it collected taxes from medical residents and their employers on wages that should have been exempt.
A spokesman for the IRS did not return a message for comment on Sunday.
