Free tax assistance: The Bedford Council on Aging and the Bedford Library offer free tax assistance primarily for low- to moderate-income seniors, prepared by qualified volunteers. When the client leaves the interview, they take all their documentation with them so that nothing is left with the volunteer, and the returns are subsequently electronically filed, unless the client prefers that a paper return be mailed.

There are limited returns that the IRS does not permit the COA to prepare, such as rental properties as well as some business returns, but in general, most every other return is acceptable. After someone schedules an appointment, he or she will receive a letter outlining the documentation required, as well as an intake form to assist in preparing for the interview. If someone needs to cancel the appointment for any reason, the COA requests a call in order to assist another taxpayer in that same time slot. To schedule an appointment at the Council on Aging, call 781-275-6825.
