R&B singer Ronald Isley (search) was convicted of multiple counts of tax evasion Monday and could face up to 26 years in prison when he is sentenced.

A federal jury convicted Isley, 64, of five counts of tax evasion and one count of willful failure to file a tax return, Assistant U.S. Attorney Thomas D. Coker said in a statement. Isley's sentencing was set for Jan. 9.

Prosecutors said Isley evaded the IRS by demanding case payments for millions of dollars in performance fees he earned between 1997 and 2002.

He also put homes and a yacht in the names of his then-wife or corporations, and cashed royalty checks belonging to his late brother, O'Kelly Isley, according to the government.

Isley's latest albums, released last year, were a collaboration with Burt Bacharach, titled "Here I Am," and the Grammy-nominated Isley Brothers CD, "Body Kiss."
