How Property Tax Works

Aroostook County, Maine operates under a property tax system that serves as the primary funding mechanism for local municipal services, schools, and county operations. Property owners in Aroostook County pay taxes based on the assessed value of their real estate, with rates varying significantly by municipality within the county. The effective tax rate for 2025 is approximately 7.70% with a mill rate of $21.99, though this represents just one municipality's rate as each town and city within Aroostook County sets its own tax rate based on local budget needs.

Property taxes in Aroostook County fund essential services including public education, road maintenance, public safety, and municipal operations. Unlike some states, Maine has no assessment cap, meaning property values can increase without limitation based on market conditions. However, the Maine Homestead Exemption Program provides qualified homeowners with property tax relief by reducing the taxable value of their primary residence, helping to moderate the impact of rising property values on long-term residents.

Supplemental Tax Bills

Supplemental taxes in Aroostook County are additional property tax assessments issued when there are changes to property ownership, value, or characteristics after the main tax roll has been established. Common triggers include new construction completion, property improvements, ownership transfers that prompt reassessment, or correction of assessment errors. These supplemental bills are calculated using the same tax rate applied to the additional assessed value.

For example, if you complete a home addition valued at $50,000 after the assessment date, you would receive a supplemental tax bill for the remaining portion of the tax year. Using the example rate of $21.99 per $1,000, the supplemental tax would be approximately $1,100 ($50,000 ÷ 1,000 × $21.99), prorated for the remaining months in the tax year. Supplemental taxes are typically due within 30 days of the bill date and become delinquent if not paid by the specified due date.

Escrow & Property Taxes

Most mortgage lenders in Aroostook County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly property tax payments along with your mortgage payment and holds these funds in an escrow account. The lender then pays your property taxes directly to the municipality when due. Escrow payments are calculated by dividing your annual tax bill by 12, often with an additional cushion to account for potential tax increases.

Property tax bills in Aroostook County are typically mailed in August for taxes due October 1st of the following year. Lenders receive these bills directly and pay them from your escrow account before the due date. Your lender will provide an annual escrow analysis showing how your payments were used and any adjustments needed for the coming year. If your taxes increase significantly, your monthly escrow payment may increase accordingly. You can verify your property tax payments and balances by contacting your municipality directly or checking online payment systems where available.
