Maine Property Tax Rates by Town (2026)

How Maine Property Taxes Work

Maine property taxes are set at the local level — every city and town sets its own mill rate. There is no statewide property tax. The mill rate is expressed as dollars per $1,000 of assessed value.

The formula: Assessed Value × Mill Rate ÷ 1,000 = Annual Tax Bill

Example: A home assessed at $300,000 with a mill rate of 14 owes $4,200 per year.

Maine requires municipalities to assess properties at 70% to 110% of market value. Many towns that haven’t revalued recently assess below market value, pushing mill rates higher to compensate — which is why comparing mill rates across towns without knowing the assessment ratio can be misleading.

Maine Mill Rates and Property Tax Rates by Town (2024)

A mill rate is the amount of property tax charged per $1,000 of property value, so a mill rate of 10 means $10 of tax for every $1,000. Every Maine town sets its own rate each year, which is why bills differ so much from one town to the next. The 2024 state weighted average is 10.37 mills, or $10.37 per $1,000.

The rates below are Maine Revenue Services’ estimated full-value rates for all 483 municipalities that report one. They adjust for how much of each town’s value is actually assessed, which makes towns comparable. They are not the rate printed on a tax bill. A town’s posted mill rate is applied to its own assessed values, so the two often differ. Use these numbers to compare towns, and use your town’s posted mill rate and assessed value for your actual bill.

For example, Wells is $5.79 per $1,000, so a $400,000 home would carry roughly $2,316 a year before exemptions. Bangor is $16.42, which is about $6,568 on the same value.

Maine Property Tax vs. New England

Maine’s effective property tax rate of approximately 0.98% is below the New England average. Connecticut (1.79%), Vermont (1.83%), and New Hampshire (1.93%) all pay more as a share of home value. Massachusetts (1.12%) and Rhode Island (1.53%) are also higher.

Estimating Your Tax Bill

1. Find the town’s current mill rate at Maine Revenue Services or by calling your town assessor
2. Find the property’s assessed value (from town assessor or most real estate listings)
3. Subtract $25,000 if you qualify for the Homestead Exemption
4. Multiply adjusted assessed value by mill rate, divide by 1,000

Example: $350,000 assessed value, $25,000 Homestead Exemption, 14.0 mill rate
($350,000 – $25,000) × 14.0 ÷ 1,000 = $4,550 per year

Property taxes are typically due in September or October, with many towns offering two semi-annual installments.
