Helena, MT -

A former Helena man who was convicted of attempted tax evasion has been sentenced to nearly four years in federal prison and ordered to pay $730,000 in restitution.

The Independent Record reports U.S. District Judge Charles Lovell sentenced 51-year-old Bradley Fisher of Kenmore, Wash., on Tuesday. Fisher apologized, saying he was humiliated and had and embarrassed his family and friends.

Court records say Fisher worked as an insurance salesman but did not file tax returns from 2001 to 2006. An IRS audit determined he owed nearly $445,000, plus penalties and interest. Fisher made about $44,000 in payments.

As the IRS sought to collect the money over the years, prosecutors say Fisher failed to disclose his ownership interest in five vehicles and a boat and took expensive vacations. The IRS eventually seized and sold his house.
