Federal prosecutors say a Binghamton man is admitting he attempted to interfere with the Internal Revenue Service.

U.S. Attorney Richard Hartunian and IRS Criminal Investigation Special Agent, Shantelle Kitchen say 40 year old Donald Grant has pleaded guilty to preparing 27 tax returns containing false information.

Prosecutors say Grant admitted that over four years he prepared returns that contained false claims of business income, business losses and educational expenses that gave 13 clients more than $100,000 in refunds to which they were not entitled.

He also admitted he encouraged clients to provide false information to investigators.

Grant faces up to 3 years in prison for each of two counts and a maximum fine of $100,000 for preparing a false return and $5,000 for interfering with Internal Revenue Laws.

Sentencing is set for March.
