LOUISVILLE, Ky. (WDRB) -- Employees at the University of Louisville are on alert after thieves stole electronic tax forms.

The university confirms 83 employees had fraudulent activity associated with their W-2 information after a breach at Equifax, the company that provides access to the forms online.

The accounts of 750 employees show potential fraudulent activity.

U of L officials do not believe the stolen information will prevent anyone from getting their tax return, but the co-owner of Stober's Tax Service says it could cause problems if criminals use the data to file bogus returns.

"The first year, it's very detrimental because then your refunds can be held up for six months or a year, however long it takes the IRS to figure out who the money actually belongs to," co-owner Steven Stober said.

Equifax has increased security on the website and is providing credit monitoring to employees affected by the breach.
