Hatch is scheduled to appear Wednesday in federal court in Rhode Island to answer charges he violated the terms of his three-year probation, which began after he got out of prison last year.
The complaint is not public, so the alleged violation was not clear Friday. His public defender did not immediately return a message left by The Associated Press.
Hatch was required to refile tax returns and pay back taxes. He has maintained he doesn't owe taxes, telling The Providence Journal last month that the Internal Revenue Service had given him two refund checks, saying that was proof he owed nothing.
