A Bridgewater woman on state probation for embezzling money from the Canterbury School in 2004 has admitted she failed to pay taxes on money she had stolen three years ago from a New York-based, software company.

Deborah Wilmot, 42, pleaded guilty in federal court in New Haven to keeping more than $69,000 from the government by not reporting as income more than $220,000 she embezzled while working as a bookkeeper for Amkai Solutions during 2008 and 2009.

Amkai, located in Armonk, N.Y., provides software services to hospitals and surgical centers, according to the company website.

U.S. Attorney David B. Fein said Ms. Wilmot convinced her employer to open a separate bank account to handle international transactions, then wrote checks and withdrew cash for her personal use.

She also altered customers checks so they were payable to her, Mr. Fein said.

Ms. Wilmot, who waived indictment on tax evasion charges, faces up to five years in prison when she is sentenced May 29 by U.S. District Judge Ellen Bree Burns. She also must make restitution to the Internal Revenue Service for the back taxes, plus interest.

At the time the government said she was embezzling the money from Amkai, Ms. Wilmot was on five years of probation imposed by a state Superior Court judge in Litchfield as part of her sentence for stealing more than $100,000 from Canterbury School, a private high school in New Milford.

Ms. Wilmot worked there between 2001 and 2003 as assistant controller.

She was sentenced to a 15-year prison term, suspended after she served three years, on the state charges and could be required to serve more state time if she is found guilty of violating probation.

Ms. Wilmot had also pleaded guilty to a sixth-degree larceny charge brought by New Milford police in 2010, but served no jail time, according to state court records.
