A Central Point couple must go to prison and pay more than $400,000 in back taxes to the government after willfully failing to file federal income tax returns, a judge has ruled.

A Central Point couple must go to prison and pay more than $400,000 in back taxes to the government after willfully failing to file federal income tax returns, a judge has ruled.

Kenneth L. Anderson, 63, and Dorothy S. Anderson, 61, were sentenced by U.S. Magistrate Judge Thomas M. Coffin Monday in Medford's U.S. District Court to 14 months in prison. In addition to paying back taxes, they also must file delinquent tax returns.

The couple pleaded guilty in June to two counts of willfully failing to file federal income tax returns for 2004 and 2005, according to a press release from the Department of Justice.

The Andersons had sold Mannatech Inc. health care supplements, both individually and through their corporation, AGK Services, since 1994. The Anderson had not filed tax returns since 1987, the government said, even as they earned more than $1.3 million in commissions between 2002 and 2004.

In response to contacts by the IRS, Kenneth Anderson responded with frivolous letters, failed to respond and failed to appear for scheduled meetings with the IRS, the Department of Justice release said.

After serving their sentence, the Andersons will be on one year of supervised probation.
