Hamilton man pleads guilty to tax fraud and embezzlement

Jonathan Shawn Thomsen defrauded his employer for more than $500,000

A Hamilton man has pleaded guilty in U.S District Court in Cincinnati to filing a false income tax return and wire fraud.

Jonathan Shawn Thomsen, 39, was charged March 2020 with the crimes through a bill of information and entered the plea today.

According to court documents, from June 2006 until April 2017, Thomsen was employed as a project manager for Natus Medical Inc. headquartered in Pleasanton, Calif. Natus manufactures medical devices and serves as a software and service provider to hospitals, clinics and laboratories worldwide.

From May 2012 to April 2017, Thomsen embezzled funds in excess of his authorized pay and compensation, according to an IRS press release. Thomsen submitted false claims for reimbursements of business travel expenses that he had not incurred.

He routinely requested reimbursement for fake airlines tickets that he created using editing software, the IRS release states. Thomsen would have payments made to his American Express corporate credit account. He would use the credits on the American Express card for personal expenditures including forming a side business and transferring money to his spouse’s PayPal account, the IRS said.

When Natus shifted its corporate credit card accounts from American Express to Citibank, Thomsen began to falsely claim that he had incurred and paid for travel expenses out of his personal funds. From February 2016 until the fraud was discovered in April 2017, Natus deposited reimbursement payments directly into Thomsen’s bank account

In total, Thomsen requested reimbursement for more than 1,000 false and fraudulent expense reports under this scheme and defrauded his employer of $517,737.

In addition, Thomsen filed false tax returns for the years 2013 through 2017. Thomsen failed to include the embezzled funds as income as well as not reporting or underreporting the gross receipts from the side business he formed. The total tax loss for 2013 through 2017 is $175,774.

Filing a false income tax return carries a maximum penalty of 3 years in prison and a fine not to exceed $250,000. Wire fraud carries a maximum penalty of 20 years in prison and a fine not to exceed $250,000.

Thomsen has not yet been sentenced and according to online court records, a date has not been set.

The case is being prosecuted by Assistant United States Attorney Ebunoluwa A. Taiwo and was investigated by special agents of IRS-Criminal Investigation.
