Maine property taxes typically rise between about 2% and 5% per year for most towns, with a long-run statewide average that sat near 6.6% before the state imposed a levy cap in 2005 and has run closer to 3% since. How much your own bill goes up in any given year depends on three things: what your town votes to spend, whether your property has been revalued recently, and how fast the local tax base is growing. There is no single statewide number that answers how much do Maine property taxes increase per year, because the levy is set town by town.
In the first year after the levy cap took effect, statewide property tax commitments grew about 1.6%, and state budget analysts projected roughly 3% annual growth going forward under the new limits. Most municipalities have landed in that 2% to 5% corridor since, with occasional outlier years when a town passes a large school budget, completes a revaluation, or absorbs a sharp change in state aid.
Why Your Town’s Increase May Be Higher or Lower
Local conditions do most of the work. Coastal communities and towns near Portland or Bangor tend to see steeper increases because rising home sale prices push assessed values up, which lifts the total taxable base. Rural towns face the opposite pressure. When population shrinks, fewer taxpayers share the cost of schools, roads, and emergency services, and per-household bills can climb even when the overall budget barely moves.
A town with new commercial development can sometimes hold residential increases down by spreading the levy across a larger base. A town that just completed a revaluation may see dramatic shifts between neighborhoods even though the total raised stays flat. The number you care about is not the statewide average but your own town’s year-over-year mill rate and your own property’s assessed value.
The LD 1 Levy Limit
Maine law caps how fast a municipality can grow its total property tax levy from one year to the next. The cap is widely known as LD 1, originally enacted in 2005 under 30-A M.R.S. §5721-A. That section was repealed in 2023 and replaced by §5721-B, which carries forward the same framework with updated mechanics. The limit applies to municipal operating budgets. It does not cover county assessments, K-12 school funding governed by the state education formula, or tax increment financing districts.
Each year the municipality calculates a growth limitation factor combining two components: statewide average real personal income growth, and a local property growth factor that accounts for new construction and other property that became taxable for the first time. The prior year’s levy limit is multiplied by one plus that factor to produce the new ceiling. The formula is built so municipal tax growth roughly tracks residents’ ability to pay.
Towns can exceed the limit, but only with an explicit vote. The legislative body or a town meeting must approve the overage by written ballot on a separate article that identifies the intent to go above the cap. Some towns put the question to a full referendum. Either way, voters get a direct say before spending crosses the line, which is a useful thing to know if your bill jumped and you want to understand what happened.
How Your Bill Is Actually Calculated
Every Maine tax bill comes down to two numbers multiplied together: your property’s assessed value and the local mill rate. The mill rate is the tax charged per $1,000 of assessed value. A home assessed at $200,000 in a town with an $18.00 mill rate owes $3,600 for the year.
The order of operations matters. The local legislative body first decides how much total revenue needs to come from property taxes to fund municipal services, schools, and county assessments. The assessor’s office then divides that amount by the total taxable value of all property in the municipality, and the result is the mill rate. This means the rate can drop in a year when property values rise faster than spending, even though individual bills still go up because each home’s assessed value increased. Looking only at the mill rate hides half the story.
Why Revaluations Cause Sudden Jumps
Property owners sometimes see stable bills for several years and then a noticeable jump. That pattern usually traces back to a revaluation. Maine requires municipalities to keep assessed values reasonably close to actual market value. When the gap grows too wide, the town must update its assessments, either through a full revaluation with physical property inspections or a statistical update that adjusts values using recent sales data.
A revaluation does not automatically raise the total amount of tax collected. Its purpose is fairness, making sure each property carries its proportional share of the levy based on current worth. If every home in town doubled in value, the mill rate could be cut in half and each owner would owe roughly the same amount. In practice, some properties appreciate faster than others, so a revaluation shifts the burden toward owners whose homes gained the most value and away from those whose properties lagged the market. If your bill rose far more than your neighbors’, a revaluation is often the reason.
What to Do If Your Increase Looks Wrong
If you believe your property is assessed above its actual market value, Maine offers a formal abatement process. Start by requesting your property record card from the local assessor’s office. The card contains the data used to calculate your assessment: lot size, building dimensions, condition ratings, and comparable sale prices. Errors are more common than people expect, and fixing a wrong square footage or an incorrect number of bathrooms can lower your bill without a formal dispute.
When the data is correct but the value still looks too high, you can file a written abatement application with the assessor. The deadline is 185 days from the municipality’s commitment date, which is the date the assessor formally commits the tax roll for the year.1Maine Revenue Services. Property Tax Abatement and Appeals
If the assessor denies the abatement, you can appeal to the local Board of Assessment Review within 60 days. The board holds a public hearing where you and the assessor each present evidence. To win, you generally need to show that the assessment was substantially above market value or that there was discrimination between similarly situated properties. Disagreeing with a modest increase, or arguing that taxes are unaffordable, is not enough. A property valued within about 10% of its likely sale price is typically upheld. If the local board denies your appeal, you can escalate to the Maine State Board of Property Tax Review.
Programs That Reduce What You Owe
Even when the increase is legitimate, several state programs can take a chunk out of the bill. Each is filed through the local assessor’s office with an April 1 deadline, except the Property Tax Fairness Credit, which is claimed on your state income tax return.2Maine Revenue Services. Property Tax Relief
Homestead Exemption
Any permanent Maine resident who has owned a home in the state for at least 12 months can apply for the Homestead Exemption, which removes $25,000 from the property’s taxable value. In a town with a $20 mill rate, that is $500 in annual savings. You apply once, and the exemption renews automatically each year as long as you continue to occupy the home as your primary residence.3Maine State Legislature. Maine Code Title 36 681 – Definitions
Property Tax Fairness Credit
The Property Tax Fairness Credit works differently from the exemptions. Rather than reducing your assessed value, it provides a refundable credit on your Maine income tax return. If you owe no state income tax, the credit is paid out as a refund. For the 2025 tax year, the maximum is $1,000 for most filers and $2,000 for residents age 65 or older. Renters who pay property tax indirectly through rent can also claim it.4Maine Revenue Services. Property Tax Fairness Credit Summary
Eligibility depends on income and filing status. Single filers must have Maine adjusted gross income below $63,750. Married couples filing jointly face a threshold between $82,500 and $101,250 depending on dependents. Residents 65 and older qualify with income up to $102,500. Married couples filing separately cannot claim the credit at all.
State Property Tax Deferral for Seniors and Disabled Homeowners
Homeowners who are at least 65 years old, or permanently disabled and unable to work, may defer property taxes rather than pay them each year. The state pays the municipality on the homeowner’s behalf, and a lien is placed on the property. The deferred taxes plus interest come due when the home is sold or transferred.
To qualify, all owners must have combined income below $80,000 and combined liquid assets below $150,000 for a single owner or $100,000 for multiple owners. Applications are filed with the local assessor between January 1 and April 1. The assessor verifies the information and forwards the application to Maine Revenue Services, which makes the final eligibility decision. Once accepted, enrollment continues automatically in future years unless circumstances change or a repayment event occurs. A denied application can be appealed to the State Board of Property Tax Review within 30 days.
