AUGUSTA — The state has filed 23 charges against an Acton man in connection with tax evasion over a six-year period.

Richard Weymouth, 65, was indicted Friday by a Kennebec County grand jury on four counts of intentional evasion of income tax, six counts of intentional evasion of use tax, five counts each of intentional evasion of sales tax and failure to pay tax, and one count each of unsworn falsification, failure to make and file Maine income tax returns and false homestead exemption filing.

An indictment is not a determination of guilt, but it indicates that there is enough evidence to proceed with formal charges and a trial.

According to the indictment, Weymouth was a resident of Maine and received taxable income in the tax years 2006 through 2009. However, the indictment says Weymouth claimed to be a resident of New Hampshire, “which reduced his federally adjusted gross income.”

Weymouth also is accused of intentionally evading Maine use tax by buying vehicles, including commercial vehicles, out of state, filing titles for them in New Hampshire and storing them in Maine from 2009 to 2012. It also says he bought some vehicles in Maine, failed to pay sales tax and falsely completed an affidavit claiming residency in New Hampshire.

The indictment also says Weymouth claimed in an application for the state’s homestead exemption in April 2011 that he was a permanent resident of Maine while simultaneously claiming to live in New Hampshire.

An document allegedly signed by Weymouth in April 2011 — and attached to the indictment — seeks exemption from Maine sales tax for a trailer and indicates he lives in Rochester, N.H.

Attempts to reach Weymouth by phone Friday were unsuccessful.
