Snipes failed to file tax returns from 1999 to 2004. In court he pleaded not guilty to charges, saying he was not required to pay the tax bills. Snipes, who is a member of a group that challenges the government's right to collect taxes, was acquitted of the most serious charges in 2008, but he was convicted on three misdemeanor counts for not filing a tax return. After failed appeals, he is now serving a three-year sentence in a federal prison in Pennsylvania. The "Blade" trilogy star also may be forced to pay $13 million in back taxes and fines.
