The "Lean Back" rapper, whose real name is Joseph Cartagena, surrendered Monday, his attorney told Associated Press.
The 42-year-old pleaded guilty in December after failing to pay income taxes in 2007 and 2008 on income that totaled more than $1 million.
He is being held at the Federal Detention Center in Miami, according to TMZ, and will have to pay a $15,000 fine and serve an additional year under supervised release. He initially faced up to two years in prison for the crime.
"I did everything I possibly can to correct the situation," the rapper told Fuse this month. "I paid them back. It wasn't entirely my fault. I had a new accountant for like the last four years. And then you could see that my accountant that worked for me for the 15 years prior to that always paid my stuff on time, always had it on time."
Joe's attorney said that he was in positive spirits and looking forward to getting released and back to his family before Christmas, AP reported.
