T.I.'s attorney, Steve Sadow, tells TMZ the rapper -- who's been serving the last 30 days of his sentence under house arrest -- will officially be done today.
T.I. will now be placed under 23 days of supervised release ... which means he'll have to be home by 11 PM unless he's performing, which he'll have to be in by 1 AM.
The rapper -- real name Clifford Harris -- will also have to complete 400 hours of community service and will be on probation for three years.
