CEDAR RAPIDS, Iowa (AP) — A tax preparer has been sentenced to a year and day in prison for preparing fraudulent returns. Prosecutors say 49-year-old Serge Cibuyi was sentenced Tuesday in Cedar Rapids. He’d pleaded guilty to one count of preparing and filing a false tax return.

In his plea agreement Cibuyi admits that, while living in Cedar Rapids, he prepared fraudulent returns by claiming false deductions and credits or by inflating legitimate deductions and credits. Cibuyi paid people to let him use their dependents on other taxpayers’ returns to boost refunds.

Prosecutors say he prepared and filed at least 36 false tax returns with a tax loss to the United States in excess of $100,000.
