Board of Assessors

At the December 8, 2025 Public Hearing, the Select Board enacted the Single Assessor Ordinance which goes into effect following the June 10, 2026 Town Meeting.
Until then, the Town's three-member Board of Assessors will continue to serve in their full capacity.
After extensive research and thoughtful conversations between the Select Board, the Board of Assessors, and the Assessors’ Agent, there is a shared belief that transitioning to a single, certified assessor will best position Thomaston for the future. This model, common among many Maine communities, provides consistency, technical expertise, and continuity as the Town prepares for major projects, including the upcoming revaluation.
This transition follows the process outlined in M.R.S. Title 30-A, §2526, which allows a municipality to shift from an elected board to a single appointed assessor. Unlike most ordinances adopted at Town Meeting, state law permits the Select Board to enact this ordinance at least 90 days before the Annual Town Meeting at which it becomes effective. With Thomaston’s meeting held in June, the Select Board is initiating this process now to ensure transparency and allow ample opportunity for public input. The Select Board expresses sincere gratitude to the Board of Assessors for their years of commitment, professionalism, and public service.

It is the job of the Thomaston Assessing Department to determine real estate and personal property values while making sure that they are: fair and equitable, thorough and complete, and in accordance with the standards established by the State of Maine. The work performed by the Assessor's Agent is overseen by the elected Board of Assessors. The Assessing Department is responsible for accurately determining the value of property located within the Town of Thomaston for the purpose of taxation. Assessors are obligated under law to assess all property at its just value as of the 1st of April each year. This department is also responsible for the administration of all property data records. We maintain accurate parcel ownership (data) based on recorded property transactions we receive from the Knox County Registry of Deeds and all map data pertinent to accurate parcel identification.
Please EMAIL the assessing department for copies of property record cards or other data. Our property cards are not currently available online.
The State of Maine provides a measure of property tax relief through different programs to qualified individuals.

State Property Tax Deferral Program
The State Property Tax Deferral Program is a lifeline loan program that can cover the annual property tax bills of Maine people who are ages 65 and older or are permanently disabled and who cannot afford to pay them on their own. The loan program allows Maine’s most vulnerable community members to age in place and ensures that property taxes are still delivered to municipalities, requiring repayment of the loan once the property is sold or becomes part of an estate.
Eligible Maine taxpayers may receive a portion of the property tax or rent paid during the tax year on the Maine individual income tax return whether they owe Maine income tax or not. If the credit exceeds the amount of your individual income tax due for the tax year, the excess amount of credit will be refunded to you.
