Wesley Snipes reported to a federal prison in Pennsylvania on Thursday to begin his 3-year sentence for failing to pay taxes.
The 48-year-old star of the "Blade" films was ordered last week to surrender voluntarily and begin serving time after his request for a new trial was denied.
He was convicted in 2008 and prosecutors said he owed some $2.7 million in back taxes he failed to claim between 1999 and 2001 and had earned $38 million since 1999. He has until now remained free on bail.
"He surrendered a short time ago and is now inside the facility," a Federal Bureau of Prisons spokesman told the Reuters news wire. "He'll go through an orientation process and will begin serving his sentence."
The actor has apologized for his actions, saying he was "unschooled in the science of law and finance". He added that he thought the sentence was unreasonable and he should have been considered for probation.
Snipes lost an appeal regarding his case in July. His lawyers have said they believe two jurors prejudged the case. They also say Snipes' tax filings are now current.
Snipes recently starred in the movies "Game of Death" and "Gallowwalker". He is also attached to the movie "Chronicles of the Mayan Tunnel," which is due in 2012, and "Master Daddy", a 2011 film that also stars fellow action flick icon Chuck Norris.
