How to Appeal Property Taxes in Maine: Step-by-Step Guide for 2026
TL;DR
Maine homeowners can appeal their property tax assessment by filing with their Municipal Board of Assessment Review. The deadline is within 185 days after commitment of taxes (varies by municipality, typically February-April). The average effective property tax rate in Maine is 1.30%, and the average homeowner pays around $3,510 per year on a $270,000 home. If your assessment is too high, an appeal could save you hundreds or even thousands annually.
Property taxes in Maine are based on your property's assessed value, which is determined by your county assessor. If that value is too high, you pay more than you should. The appeal process exists specifically to correct these errors, and it costs nothing to file.
Here is exactly how to appeal your property taxes in Maine in 2026, including deadlines, procedures, and tips for building a winning case.
How Maine Property Tax Assessments Work
Maine assesses property at 100% of just value (though many municipalities assess at less than 100%). The valuation date is April 1, meaning your property's value is based on market conditions as of that date. Notices available when commitment date is set, varies by town.
The fiscal year runs July 1 - June 30 (most municipalities). Tax bills are calculated by multiplying your assessed value by the local mill rate (or tax rate), which is set by your county, city, school district, and other taxing authorities.
Key Deadlines for 2026
| Event | Deadline/Date |
|---|---|
| Valuation date | April 1 |
| Assessment notices mailed | Notices available when commitment date is set, varies by town |
| Appeal deadline | Within 185 days after commitment of taxes (varies by municipality, typically february-april) |
| Further appeal | County Superior Court or State Board of Property Tax Review |
Step-by-Step: How to Appeal Your Maine Property Tax Assessment
Step 1: Review Your Assessment Notice
When you receive your notice, check every detail. Verify the square footage, lot size, number of bedrooms and bathrooms, year built, and any special features. Errors in property characteristics are the easiest wins in an appeal because the facts speak for themselves.
Step 2: Research Comparable Sales
Look for 3-5 homes similar to yours that sold near the valuation date (April 1) for less than your assessed value. Good comps share your neighborhood, approximate size, age, and condition. The closer the match, the stronger your case.
Step 3: File Your Appeal
File your appeal with the Municipal Board of Assessment Review within 185 days after commitment of taxes (varies by municipality, typically February-April). In most Maine counties, you can file by mail, in person, or online (check your county assessor's website). Include a written explanation of why you believe your assessment is too high, along with your supporting evidence.
Step 4: Prepare Your Evidence
Strong evidence includes:
- Comparable sales data: Recent sales of similar properties at lower values
- Property condition issues: Foundation problems, outdated systems, needed repairs, environmental issues
- Photos: Document any defects or conditions that reduce your property's value
- Equity arguments: Show that comparable properties in your area are assessed lower than yours
- Independent appraisal: A recent professional appraisal showing a lower value
Step 5: Attend Your Hearing
Present your case clearly and concisely. Stick to facts and data. Bring copies of all evidence for the board members. Be respectful but firm. If you have a professional appraisal or contractor estimates for repairs, those carry significant weight.
Step 6: Further Appeals If Needed
If you disagree with the Municipal Board of Assessment Review's decision, you can escalate to County Superior Court or State Board of Property Tax Review. Each level of appeal has its own deadlines, so act quickly if you want to continue.
County-Specific Appeal Information
Cumberland County (Portland)
Portland and surrounding towns have seen rapid appreciation. The city assessor's office handles Portland valuations. Each municipality manages its own assessments independently. File your abatement application with the municipal assessor.
York County
Southern Maine's beach and resort communities (Kennebunk, Old Orchard Beach) have volatile values. Seasonal property valuations require careful comp selection.
Penobscot County (Bangor)
Bangor is the commercial hub of northern Maine. Values here are more stable than coastal areas. Check that the assessor's sales ratio study supports your claimed overvaluation.
Androscoggin County (Lewiston/Auburn)
Twin cities with different assessment practices. Compare how each municipality values similar properties.
Maine Property Tax Exemptions
Before or alongside your appeal, make sure you are claiming every exemption you qualify for. Exemptions reduce your taxable value directly, saving you money every year.
| Exemption | Details |
|---|---|
| Homestead Exemption | $25,000 reduction in assessed value for primary residence owned for at least 12 months |
| Veteran Exemption | $6,000 reduction for veterans who served during wartime periods |
| Blind Exemption | $4,000 reduction for legally blind residents |

Tips for a Successful Maine Property Tax Appeal
Focus on Comparable Sales
The single most persuasive piece of evidence is comparable sales data showing similar homes sold for less than your assessed value. Boards and assessors deal in market data. Give them solid numbers.
Check for Property Record Errors
Assessors work from property records that may contain mistakes. Wrong square footage, extra bathrooms, incorrect lot size, or a missing condition note can inflate your value. Verify everything against your actual property.
Document Property Condition Issues
If your home needs a new roof, has foundation issues, or has other problems that a buyer would negotiate on, document them with photos and repair estimates. The assessor may not know about these issues.
File Every Year
Even if you won last year, your assessment can go up again this year. Make annual appeals part of your routine. There is no penalty for appealing, and your assessment cannot go up as a result of your appeal in most jurisdictions.

Frequently Asked Questions
What is the deadline to appeal property taxes in Maine?
The deadline is within 185 days after commitment of taxes (varies by municipality, typically February-April). Missing this deadline generally means waiting until next year, so mark your calendar.
How much does it cost to appeal property taxes in Maine?
Filing an appeal is free. You may incur costs only if you hire a professional appraiser, attorney, or if you escalate to court. The initial appeal to the Municipal Board of Assessment Review costs nothing.
Can my property taxes increase if I appeal?
In most cases, your assessed value will not increase as a result of filing an appeal. The worst outcome is typically that your value stays the same. However, if the review board discovers a significant error that understated your value, a correction is possible in rare cases. This is uncommon.
Do I need a lawyer to appeal?
No. The appeal process is designed for property owners to handle themselves. For high-value or complex properties, professional help can be worth it, but most residential appeals are straightforward.
How long does the appeal process take?
The initial appeal typically takes 1-3 months from filing to decision. Further appeals to County Superior Court or State Board of Property Tax Review can take additional months.
What evidence works best in a property tax appeal?
Comparable sales of similar homes that sold for less than your assessed value are the strongest evidence. Property condition documentation, independent appraisals, and equity comparisons with similarly assessed nearby properties also carry weight.
