Maine · Do-it-yourself · $29

Appeal your Maine property taxes yourself.

Maine's window is OPEN right now, and it is the only state where the deadline is a date your own town picks and does not have to print anywhere. This kit shows you how to find your commitment date, how to use the certified ratio to recover what the town really thinks your house is worth, and the 10 percent rule that decides in one calculation whether your appeal is worth filing.

Straight talk: we don’t have per-home comparable-sales data for Maine — Maine property records are held by roughly 480 individual municipalities rather than by counties or the state, and there is no statewide per-parcel dataset with the building detail needed to size-adjust a comparable set. So this is a guide and templates, not a comp report, and you pull your own comps— the kit shows you exactly how. That’s the honest reason it’s $29 instead of the $49 done-for-you kit we sell in states we cover.

How a Maine appeal works

The short version, free. The kit is the long version with the forms, the filing steps, and the letter.

  1. Maine has no statewide deadline. You have 185 days from your own town's COMMITMENT DATE, the day the assessors commit the tax list to the collector, and commitments run from July to September so most deadlines land in January to March.
  2. The commitment date is not legally required to appear on your tax bill. Call the assessor and ask for it; Maine Revenue Services own form tells you to.
  3. Maine towns assess at a published percentage of market value called the certified ratio. Divide your assessed value by it to recover what the town really thinks your home is worth. In Lewiston, at 54%, a $300,000 assessment implies about $555,000.
  4. Then run the 36 M.R.S. 848-A test: if your deviation from the town's assessment ratio is under 10 percent, the assessment is defensible by statute and an appeal will lose. At 10 percent or more, that defence is unavailable.

What to check on your assessment notice

  • Get the COMMITMENT DATE from your assessor, then count 185 days. That is your deadline, it is jurisdictional, and no one can waive it for you.
  • Look up your town's certified ratio and divide your assessed value by it. That is the town's implied opinion of your market value, and it is often far above the assessment itself.
  • Work out your deviation from the town's ratio. Under 10 percent, stop: 848-A gives the town a complete defence. At 10 percent or more, you have a real case.
  • Check the homestead exemption on your bill. It is $25,000 of just value, but 683(1) requires it to be multiplied by the ratio, so in a 62% town it should appear as about $15,500, not $25,000.

What’s inside

✓How to find your own town's commitment date when it appears on no bill and no website, and how to count the 185 days that run from it.
✓The certified ratio arithmetic that turns a Maine assessment into the town's real opinion of your market value, with the state's own worked example.
✓The 36 M.R.S. 848-A ten percent test, which decides in one calculation whether your appeal can win, so you do not spend a season on a filing the statute already defeats.
✓The deemed-denial rule at day 60 that starts your appeal clock silently, with nothing arriving in the post to tell you.
✓The 706-A inquiry trap, which bars BOTH your application and your appeal if you ignore a mailed assessor inquiry, and how to cure it.
✓The poverty and infirmity abatement almost nobody uses, its three-year clock, and the procedural protections the town owes you.
✓Why the senior stabilization program still looks alive in the statute book and is not available, and what actually replaced it.
✓A ready-to-edit abatement application citing the right Maine statutes.

How it works

  1. Buy the kit — the PDF lands in your inbox instantly.
  2. CALL YOUR TOWN OFFICE AND ASK FOR THE COMMITMENT DATE. Maine has no statewide deadline, the commitment date is not legally required to appear on your tax bill, and Maine Revenue Services own form tells you to check with your municipal assessor to find out the exact date. Your 185 days run from it.
  3. Gather the evidence on the checklist and edit the appeal-letter template.
  4. File the Application for Abatement of Municipal Property Taxes with your MUNICIPAL ASSESSOR. Maine Revenue Services never receives it before your deadline.

Different process where you live?

Maine is not one system. These jurisdictions use a different agency, a different form, and an earlier deadline than the rest of the state. The kit covers each one in its own section.

How to find YOUR town's commitment date
Every Maine homeowner, because the deadline is municipal. This is not a place, it is the step that replaces a statewide date.
Deadline
185 days from commitment. Verified 2026 examples showing the spread: Bangor committed July 13, 2026 with a published deadline of January 14, 2027; Camden August 11; Saco August 12; Newfield August 15; Scarborough August 20; Rockport August 28; Berwick September 2; Freeport September 15.
Filed with
Your municipal assessor's office, or the town office in a town with a part-time or contract assessor.
Form
The Maine Revenue Services model Application for Abatement of Municipal Property Taxes, or your town's own form. Both satisfy the statute.
Certified ratios, and why they change the whole calculation
Every Maine homeowner. Maine towns assess at widely differing percentages of market value, and comparing an assessment to a sale price without dividing by the ratio is meaningless.
Deadline
Not a deadline. Note that the most recent published summary is the 2024 Municipal Valuation Return, published November 19, 2025; no 2025 or 2026 edition exists yet, so confirm a current-year ratio with your assessor.
Filed with
Maine Revenue Services publishes every municipality's certified ratio in the Municipal Valuation Return Statistical Summary, whose first section is titled Certified Ratio, Commitment, Tax Rate.
Form
Municipal Valuation Return Statistical Summary.
Deadline: Under 36 M.R.S. 841(1) an abatement application must be filed in writing WITHIN 185 DAYS FROM COMMITMENT, stating the grounds. Note it is 185 days, not 180. Commitment is defined by 36 M.R.S. 709: the assessors make perfect lists of the estates and commit them, when completed and signed by a majority of them, to the tax collector with a warrant. There is no date anywhere in 709. It is purely municipal, and Maine Revenue Services says only that it usually occurs about the time tax bills are first mailed. We verified 2026 commitments as early as July 13 (Bangor, giving a January 14, 2027 deadline) and as late as September 15 (Freeport, giving March 19, 2027), with most towns in August. Kennebunk states the consequence plainly: the 185-day deadline is JURISDICTIONAL and may not be waived by the assessor or by an appeal body. Do not rely on a date the town publishes without checking the arithmetic, because at least one town publishes a deadline four days later than 841 computes, and the statute controls. From the assessor, the next step is 60 days to the local Board of Assessment Review, or to the county commissioners in a town that has no Board, and then 30 days to Superior Court under Rule 80B, and then the Law Court. The trap in the middle is 36 M.R.S. 842: if the assessors fail to give written notice of their decision within 60 days of your filing, the application is DEEMED DENIED and your appeal clock starts running, unless you consented in writing to further delay. A homeowner waiting for a denial letter that never arrives can burn the entire appeal window without ever receiving a piece of paper.

What Maine charges to file

These are your county or state’s fees, not ours. Listed so there are no surprises.

  • Abatement application to the municipal assessor: FREE. We found no fee in sections 841 through 849, on the Maine Revenue Services form, in Property Tax Bulletin 10, or on any municipal source we checked.
  • Local Board of Assessment Review or county commissioners: no fee identified.
  • Superior Court, Rule 80B civil appeal: $175.00 under the Judicial Branch fee schedule effective March 9, 2026. The general civil filing fee is also $175, so the figure is robust either way.
  • Note 36 M.R.S. 843(4): taxes must be paid before appealing past the assessor, but only where the valuation is $500,000 or more, so most homeowners are not caught by it.
  • Your real cost is evidentiary. The optional item is a professional appraisal effective near April 1; the sales data and your property record card come from the assessor for free, and Maine Revenue Services tells you to ask for them.

Questions

Why is this $29 and not $49?
The $49 kit includes a comparable-sales analysis pulled from county records. We don't have that data for Maine yet, so this kit is the guide, the deadline rules, the exact form, an evidence checklist, and an appeal-letter template — you gather the comps yourself, and we show you how. Honest work, honest price.
