Maine mill rates by town generally fall between about 5 and 35 dollars per $1,000 of assessed value, with the exact figure set each year by the municipality based on its budget, its share of school and county costs, and the total value of taxable property inside its borders. One mill equals one dollar of tax per $1,000 of assessed value, so a rate of 15.00 means $15 in tax for every $1,000 your property is worth on the town’s books. Two neighboring towns providing similar services can post very different rates because each divides its own budget by its own tax base.
Where to Look Up Your Town’s Rate
For a statewide comparison, the Municipal Valuation Return Statistical Summary from Maine Revenue Services is the definitive source. It pulls tax data from all 482 municipalities and the unorganized territory, including assessed valuations, tax commitments, and mill rates.1Maine Revenue Services. Municipal Valuation Return Statistical Summary The most recent version posted online covers the 2024 tax year.
For the current year, call or check the website of the town office where the property sits. Assessors are required by state law to report valuation and tax figures to the State Tax Assessor each year, including each class of property assessed, total valuation, and the percentage of taxation.2Maine State Legislature. Maine Code 36 – Assessors Annual Return to State Tax Assessor
One thing to watch for when comparing towns: published rates come in two flavors. A town’s local mill rate applies to its own assessed values, which may be well below market. The full-value tax rate is adjusted to reflect true market value and is the honest number for comparing tax burden across towns. Maine Revenue Services publishes estimated full-value rates for every municipality.3Maine Revenue Services. Estimated Full Value Tax Rates A town assessing at 80% of market will show a higher local rate than a town assessing at 100%, even if the real tax burden is similar.
How to Calculate Your Property Tax
Take your assessed value, divide by 1,000, and multiply by the mill rate. A home assessed at $300,000 in a town with a 15.00 rate: 300,000 ÷ 1,000 = 300, then 300 × 15.00 = $4,500 for the year.
Your assessed value is not necessarily your market value. Maine requires municipalities to assess at no less than 70% of market value and no more than 110%.4Maine State Legislature. Maine Revised Statutes Title 36 Section 327 – Minimum Assessing Standards Because of that spread, a straight rate-to-rate comparison between towns can mislead. The bill you actually pay depends on both numbers together.
Why Rates Vary So Much From Town to Town
p>The spread across Maine is large. Some plantation communities post full-value rates below 2.00 per thousand, while towns like East Millinocket have historically exceeded 35.00.3Maine Revenue Services. Estimated Full Value Tax Rates Two houses that would sell for the same price on the open market can generate tax bills that differ tenfold based on which side of a town line they sit on. Three forces do most of the work.
Tax Base Size
A coastal or lakefront town with high property values spreads its budget across a large base, keeping the rate low even when spending is generous. An inland town with modest home values and little commercial property has to set a higher rate just to fund basic operations. A town doesn’t really choose its mill rate the way it chooses to pave a road. The rate is mostly what falls out when you divide the budget by the base.
School Funding
Education is typically the biggest driver of Maine property taxes. Under the state’s Essential Programs and Services model, local property taxes are targeted to cover 45% of the statewide cost of public education, with the state paying the rest.5Maine Legislature. Maine Code Title 20-A 15671-A – Property Tax Contribution to Public Education Each town’s required local share is set by applying a statewide full-value education mill rate to its total valuation. Property-rich towns often generate more than their required share at that rate and get little state subsidy. Property-poor towns get more subsidy but still face higher overall rates because their base is smaller. Voters can also approve school budgets that exceed the EPS allocation, which pushes the commitment higher; in small districts where schools eat 60% or more of the budget, a single referendum can visibly move the rate.
County Tax and State Valuation
The State Tax Assessor sets a “state valuation” for each municipality every year, reflecting full market value of taxable property. That figure is used to divide county taxes among the towns and to allocate state education aid.6Maine Legislature. Maine Revised Statutes Title 36 Section 208 – Equalization If your town’s state valuation climbs faster than the neighbors’ because of a building boom or rising waterfront prices, your town’s share of county taxes rises even when the county budget is flat.
Programs That Lower What You Actually Pay
Knowing the mill rate is only half the picture. Several Maine programs reduce either your taxable value or your out-of-pocket cost.
Homestead Exemption
If you’ve owned and occupied a home in Maine as your permanent residence for at least 12 months, you qualify for a $25,000 reduction in taxable value. That figure combines a $10,000 base with a $15,000 addition in effect since April 2020.7Maine Legislature. Maine Revised Statutes Title 36 Section 683 – Exemption of Homesteads At a 15.00 mill rate, that’s $375 a year off your bill. File the application with your local assessor by April 1.8Maine Revenue Services. Property Tax Exemptions For a jointly owned home, the $25,000 gets divided among the eligible resident owners.
Veteran Exemption
Veterans age 62 or older who served during a recognized wartime period, or who carry a 100% VA disability rating, qualify for a $6,000 exemption. Paraplegic veterans who received a VA grant for specially adapted housing qualify for $50,000. Unremarried surviving spouses and certain other family members of eligible veterans can also receive the exemption.
Property Tax Fairness Credit
This is a refundable credit on your Maine income tax return, not a reduction in your assessed value. Eligible residents can receive up to $1,000, or $2,000 if 65 or older, based on property taxes or rent paid during the year.9Maine Revenue Services. Property Tax Fairness Credit Summary Income limits apply and vary by filing status; for 2025 they ran from roughly $63,750 for single filers to $101,250 for joint filers with dependents. Because the credit is refundable, you get it even if you owe no income tax.
If Your Assessment Looks Too High
If you think your assessed value doesn’t reflect what your home would actually sell for, you can challenge it. Start with a written request for abatement to your municipal assessor. There’s no filing fee, but you need evidence: recent comparable sales, a professional appraisal, or documentation of conditions that reduce value. General disagreement with the number is not enough.
If the assessor denies the request or doesn’t respond, the next step depends on your town. Where there’s a Board of Assessment Review, you file a written appeal within 60 days of the denial and get a hearing.10Maine Legislature. Maine Revised Statutes Title 36 Section 843 – Appeals If the board also denies you, residential owners can go to Superior Court under Rule 80B. Nonresidential properties valued at $1,000,000 or more go instead to the State Board of Property Tax Review before any court appeal.
A tax-appeal appraisal typically runs $250 to $1,200 depending on the property. The math makes sense when the tax savings over several years clearly beat the appraisal cost, and a successful abatement carries forward, so the annual savings compound.
What Happens If You Don’t Pay
Maine’s collection process moves faster than many homeowners expect. Unpaid taxes accrue interest at a rate the town sets, capped by the state; for 2026 the maximum is 7%.11Office of the Maine State Treasurer. Delinquent Tax Rates
If the balance stays unpaid, the municipal treasurer can file a tax lien certificate at the county registry of deeds. That lien takes priority over all other mortgages and encumbrances.12Maine State Legislature. Maine Revised Statutes Title 36 Section 943 – Tax Lien Mortgage; Redemption; Discharge From the recording date, you have 18 months to pay the overdue taxes plus interest and costs. If you don’t, the lien automatically forecloses and the town takes the property. No auction, no court hearing at that stage.
The treasurer must send written notice of the impending foreclosure between 30 and 45 days before the deadline, by certified mail or hand delivery, to both the owner and any mortgage holders of record. Failure of notice extends the deadline by 30 days after notice is eventually given, and mortgage holders who weren’t notified get a separate three-month redemption window. Those protections don’t help anyone who ignores the mail. Losing a home over a few thousand dollars in back taxes happens in Maine every year, and it’s almost always preventable by calling the town treasurer early to set up a payment arrangement.
