Mission Statement

The City Assessor is charged by State law with discovering, describing, and valuing property, as well as the ownership of that property, for the purpose of taxation. Annually, the Assessor prepares a list of these properties and commits the assessments to the City Tax Collector for collection. The records compiled by the Assessor are made available for public inspection at City Hall. The Assessing Office then reports to the Maine Revenue Services - Property Tax Division regarding its activities for the year. The most recent State Valuation and state sales ratio analysis is available here

The fiscal year runs from July 1st to June 30th.  Taxes are assessed as of April 1 of each year.  Taxes are assessed for the year going forward, so for example, taxes assessed on April 1, 2022 are for Fiscal Year 2023.
