A northwest Missouri will go to prison for a scheme that netted them about $800,000 in federal income tax refunds they didn’t deserve.

The U.S. Attorney’s office says Joshua and Kristen Simonson, both 35, were sentenced Monday – the husband to nearly 13 years, the wife to nearly six years.

The Oak Grove couple was convicted in December on 11 counts including conspiracy and money laundering.

Prosecutors said the Simonsons filed fraudulent returns for taxes they claimed were withheld on interest income they earned.

Joshua Simonson also was convicted of trying to conceal the money by moving it among various accounts. When the Internal Revenue Service began contacting the Simonsons, Joshua Simonson sent two fraudulent checks totaling more than $1 million to cover the funds.
