CONCORD - A Nashua woman was convicted of filing fraudulent income tax returns and then keeping $50,000 for herself.

Maria M. Ulloa, 51, was convicted in U.S. District Court after a five-day jury trial of 10 counts of filing false, fictitious and fraudulent claims for tax refunds.

She faces a maximum sentence of three years in federal prison and up to $250,000 in fines per count, or a maximum of $2.5 million in fines.

According to the U.S. Attorney's Office, Ulloa operated Main Travel, a Nashua company that provided federal income tax return preparation services.

During 2007 and 2008, she filed 10 false federal income tax returns in the names of her clients, diverting most of the inflated tax refunds to herself.

Her prosecution stemmed from an investigation by the IRS's Criminal Investigation Office in Manchester. Assistant U.S. Attorneys Nick Abramson and Bill Morse prosecuted the case.
