Bubba Sparxxx Hit With Tax Lien

According to documents filed in Georgia, the former Timbaland protege -- whose biggest song, "Ugly," came out in 2001 -- owes $29,266.88 in back taxes from the year 2006. It was originally only about $15k ... but interest and fees have nearly doubled his debt.

The State of Georgia is now garnishing Bubba's wages through BMI, a music company that dishes out royalties to artists. From March through May of this year, the state has already grabbed $3,622.45 ... which represents all the money Bubba was owed by BMI.

Sounds like Georgia is in it for the long haul.
