The Rockland County District Attorney's office told TMZ the "Usual Suspects" star owes more than $350,000 in back taxes.
"At a time when Rockland County and New York State face severe fiscal shortfalls, we cannot afford to allow wealthy residents to break the law by cheating on their taxes," the district attorney's office said in a statement. "The defendant's repetitive failure to file returns and pay taxes over a period of several years contributes to the sweeping cutbacks and closures in local government and in our schools."
Baldwin faces a possible four years in prison if convicted.
The actor is the younger brother of "30 Rock" star Alec Baldwin.
