(CNN) -- A federal appeals court has denied actor Wesley Snipes' claim that his three-year prison sentence for tax evasion was "unreasonable."

A panel of judges in the 11th Circuit U.S. Court of Appeals upheld Snipes' 2008 sentencing on three misdemeanor counts of failing to file tax returns.

"The district court acted well within its considerable discretion in sentencing Snipes to thirty-six months in prison," the judges said.

Snipes had argued that the only reasonable sentence would have been a period of probation.

Snipes had been granted bond while he appealed his conviction on federal tax charges. It was unclear when he would be required to report to prison.

Snipes argued that the judge who sentenced him in April 2008 did not consider mitigating factors like his college education, family and charitable activities.

Federal prosecutors said Snipes for nearly a decade escaped paying more than $15 million in income tax returns by sending money to overseas accounts, though they acknowledged in court that the amount was in dispute.

Before the sentencing in 2008, the actor asked the court to show mercy and offered three checks totaling $5 million as a gesture of good will.

Federal prosecutors diverted the checks to the U.S. Treasury, which accepted the payment -- but it wasn't enough.

"It's essentially a down payment, but a fraction of what he owes," Assistant U.S. Attorney Scotland Morris said at the time.

A jury convicted Snipes on the misdemeanor charges February 1, but he was acquitted of more serious felony charges of tax fraud and conspiracy. Jurors accepted his argument that he was innocently duped by errant tax advisers.

Defense attorneys in court documents suggested that to sentence Snipes harshly would be to disregard the jury's verdict.

But prosecutors, in their sentencing recommendation, said the jurors' decision "has been portrayed in the mainstream media as a 'victory' for Snipes. The troubling implication of such coverage for the millions of average citizens who are aware of this case is that the rich and famous Wesley Snipes has 'gotten away with it.' In the end the criminal conduct of Snipes must not be seen in such a light."

Snipes, who has starred in dozens of movies including the "Blade" trilogy, "Major League" and "Murder at 1600" had received the support of many of Hollywood friends. Defense attorneys filed 39 pages of testimonials about Snipes, letters from a Hollywood "Who's Who" list and also high school friends and his employees.

Actors Denzel Washington and Woody Harrelson, as well as television judges Joe Brown and Greg Mathis, submitted letters to the judge on Snipes' behalf.
