"Full House" star Dave Coulier is about to have a less than full wallet -- turns out dude owes some big bucks in back taxes.
According to the Detroit News, the 49-year-old comedian racked up a combined federal and state tax debt nearing $50,000.
Records show the IRS filed a $37,063 lien against him in March of last year -- then California followed with a $11,793 lien in May of this year.
The comic is known for his charitable fundraising -- but, as they say, charity needs to begin at home.
Calls to Coulier's rep weren't returned.
