Property Tax Relief

Certain classes of property are exempt from taxation within the state statutes (examples: government property, churches) and the Maine State Legislature has also granted property relief to individuals and businesses through exemptions, current use programs and reimbursements. The amount of tax relief provided by these programs change over time. All exemptions must be factored by the City of Caribou’s certified ratio (currently 100%). Forms are available online and at the office. Applications for real estate tax relief are due April 1 of the tax year. Forms received after April 1 will be considered for the next year.
