US actor Wesley Snipes arrived at a federal prison in Pennsylvania shortly before 5pm on Thursday to start his three-year jail sentence.
The minimum-security prison houses 300 inmates and has no perimeter fencing. However there are five roll calls a day, three of them overnight.
A spokeswoman for the prison said: "We recognise that he is high profile, but we treat all our inmates the same."
The 48-year-old was convicted in 2008 of failing to file tax returns on any of his earnings.
However, the Blade star's lawyer says that the case contains irregularities and Wesley will be seeking a review.
