I decided to check back up on this and here's what I found. Not as serious as first thought.

He was, however, found guilty on three misdemeanor counts of failing to file Federal income tax returns (and acquitted on three other "failure to file" charges). His co-defendants, Douglas P. Rosile and Eddie Ray Kahn, were convicted on the conspiracy and false claim charges in connection with the income tax refund claims filed for Snipes. Following the guilty verdicts on the misdemeanor charges, Snipes faces a maximum possible three years in prison, and awaits sentencing.
