(Title 36, M.R.S.A. – Sections 651-678) There are several classes of exempt property (property upon which real estate taxes need not be paid) such as government-owned property. The State offers several personal exemptions which are administered by this office. Personal exemptions may change from year to year as they must be factored annually by the City’s certified ratio. Forms are available on this site and at the Tax Assessor’s Office. You must apply prior to April 1 of the tax year. Forms received after April 1 will be considered for the following tax year.
