Tax Info, Rate History, & Graphs

State Law (Title 36 of the M.R.S.A.) charges the Town Assessor with the discovery, description, and valuation of all real and personal property for the purpose of taxation.

The Town of Mount Desert has a land area of approximately 39 square miles, consisting of 2,648 parcels making up around 25,000 acres, with a 2022-2023 total taxable value of $2,353,434,611. Assessed values in 2021-2022 had an average certified assessment ratio at 85% of market value. The recent town-wide revaluation has adjusted assessments to 100% market value as of April 1, 2022.

The preliminary 2023 State valuation and sales ratio analysis is available here. Please note, the state valuation and ratio analysis is calculated based on sales in 2020-2021.

The Assessor annually prepares a list of taxable property and commits the assessments to the Tax Collector for collection of funds appropriated by the Town's legislative body at the annual Town Meeting. Assessor's 2021 Annual Report can be found here

Municipal budgets determine the total amount of taxes that must be paid.  Property assessments determine how that total tax is shared among the property owners.  Maintaining equity among taxpayers is a major responsibility of the Assessor's Office.
