  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Maine Property Taxes

For the most part, municipalities administer real estate taxes in Maine. They typically use the money to pay for local services, such as public schools, libraries and law enforcement. 

Rates vary significantly depending on where in Maine you live, however. For example, the average effective rate in Hancock County is 1.00%, lowest in the state. On the other hand, the average effective rate in Androscoggin County is 1.71%, highest in the state.

If you aren’t a Maine homeowner yet, but are considering becoming one, take a look at our Maine mortgage guide. It breaks down the important information you’ll want to understand before purchasing a home in the Pine Tree State.

A financial advisor in Maine can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

How Property Taxes in Maine Work

In Maine, any person who owns real estate on April 1st of the year is responsible for paying taxes on that property. What's specifically owed depends on the just value, or market value, of the property and the local tax rate.

To determine the market value of property, local assessors use one of three methods. The most common is the sales comparison approach, which looks at the sale prices of similar nearby homes to determine what your home would likely get on the market. The other two methods are the cost approach, which calculates the cost to replace your property, and the income approach, which calculates the income your property could generate if it were rented or used for some other purpose.

There are two statewide rules that ensure local assessors value property in an equitable fashion. The first states that assessed values cannot be less than 70% of fair market value. The second is that two similar properties should never have an assessed value difference of more than 20%. Municipalities that fail to meet these standards are required to do a revaluation of all property in their district.

Maine also offers exemptions that residents can claim in order to decrease their property taxes. The homestead exemption allows Maine residents to decrease a property’s taxable value by $25,000. Senior veterans who are 62 or older may be eligible for an exemption of $6,000. An individual who is legally blind may also receive an exemption of $4,000.

Maine Property Tax Rates

The rates that appear on tax bills in Maine are generally denominated in millage rates. A mill is the tax per thousand dollars in assessed value. For example, a home with an assessed value of $150,000 and a mill rate of 20 ($20 of tax per $1,000 of assessed value) would pay $3,000 in annual property taxes.

Because assessment levels vary between municipalities in Maine, mill rates in one area cannot be directly compared to mill rates in another. For that reason, it is useful to look at average effective rates. An effective rate is the annual property tax payment as a percentage of the total home value. The table below shows average effective property tax rates for every county in Maine, along with median home values and median annual tax payments.

In Portland, the largest city in the county as well as the state, the 2020 tax rate is 23.31 mills. Since Portland assesses property at 100% of market value, that implies a tax rate of about 2.33% for real estate owners in the city.

The county’s average effective property tax rate of 1.00% is the lowest in the state and well below the state average of 1.30%. Hancock County also has the longest coastline of any of Maine’s counties, so homeowners seeking beachfront property should find plenty of options.

Rank County Property Tax Rate School Rating Home Value Growth


Our study aims to find the places in the United States where people are getting the most value for their property tax dollars. To do this, we looked at property taxes paid, school rankings and the change in property values over a five-year period.

First, we used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

Then, we calculated the change in property tax value in each county over a five-year period. Places where property values rose by the greatest amount indicated where consumers were motivated to buy homes, and a positive return on investment for homeowners in the community.

Finally, we calculated a property tax index, based on the criteria above. Counties with the highest scores were those where property tax dollars are going the furthest.
