WESTPORT — A 64-year-old Westport resident and financial advisor, who pleaded guilty to a federal charge of filing false tax returns on nearly $1.5 million, is going to prison.

Thomas Pacilio, who in 2011 co-founded Clapboard Hill Advisors LLC, a financial services business headquartered in Westport, was sentenced Thursday to a six-month prison term, followed by a year of supervision following his release.

He also was ordered to pay a $50,000 fine when he was sentenced by federal Judge Sarala V. Nagala at U.S. District Court in Hartford.

Pacilio in January waived his right to be indicted and pleaded guilty to one count of filing a false tax return.

Since filing the guilty plea, Pacilio was free on $350,000 bond, and had faced a maximum prison term of three years in the case, according to a statement from U.S. Attorney Vanessa Roberts Avery.

He is required to report to prison by June 12.

Pacilio admitted that, from the 2015 through 2018 tax years, he filed individual income tax returns that failed to report $1,476,425 as either ordinary income or capital gains, which he received after selling Clapboard Hill Advisors to McGladrey Wealth Management LLC, federal prosecutors said at the time of his guilty plea.

His failure to report that taxable income resulted in a $286,328 loss to the Internal Revenue Service, prosecutors said.

Pacilio since then has paid the taxes he owed, according to federal officials.
