KANSAS CITY, Mo. -- A former IRS employee from Grandview, Missouri pleaded guilty in federal court Wednesday to preparing fraudulent tax returns, which allowed her to illegally claim more than $200,000 in refunds from her clients. According to U.S. Attorney Teresa A. Moore of the Western District of Missouri, 64-year-old Sandra D. Mondaine, a previous contact representative for the IRS before she retired, pleaded guilty to one count of aiding and abetting in the preparation and filing of false tax returns. Man sentenced to 20 years in Kansas for child pornography charges The court announced that Mondaine admitted to preparing federal income tax returns for clients that carried false and fraudulent claims. She was charged with assisting at least 11 people to file a minimum of 39 fraudulent income tax returns from 2019 to 2021. The loss equated to about $237,329, however, the court said the parties did not agree on the total tax loss. Because Mondaine included false information on her client's tax returns, she was able to get them substantial refunds they were not entitled to. As she filed the fraudulent claims, Mondaine also charged her clients with a fixed dollar fee or a fee representing a certain percentage taken out of the tax refund. As a result of the plea deal, Mondaine is required to pay restitution to the IRS. This payment will represent the total loss associated with the tax fraud. Mondaine also agreed to a "permanent injunction" in a different civil action, prohibiting her from preparing, assisting in, directing or supervising federal tax returns. She is also unable to file any returns for any person other than herself.

This is the maximum statutory sentence she could face, however, the court has not determined the length yet. A sentencing hearing will be scheduled after investigations by the United States Probation Office are completed. The case was prosecuted by Assistant U.S. Attorney Paul S. Becker and investigated by the IRS-Criminal Investigation.
