Portland, Maine’s property tax rate for fiscal year 2026 is $11.98 per $1,000 of assessed value.1City of Portland, Maine. Assessors Notice The City Council set the rate during budget deliberations, and it applies from July 1, 2025 through June 30, 2026. On a home assessed at $400,000, that works out to about $4,792 in annual property tax before any exemptions.
How to Calculate What You Owe
Portland uses a mil rate, meaning the charge is stated per $1,000 of assessed value. Divide your assessed value by 1,000 and multiply by 11.98. A property assessed at $350,000 owes $350 × $11.98 = $4,193 before exemptions. Multiplying the assessed value by 0.01198 gets you to the same number.
The FY26 rate dropped sharply from prior years because Portland completed a revaluation that pulled assessed values closer to current market prices. When values rise across the board, the mil rate usually falls so the city doesn’t collect far more than its budget requires. That doesn’t automatically mean a smaller bill. If your home’s value climbed faster than average between revaluations, you can still owe more than you did last year.
The assessed value on your bill may not match a recent appraisal or sale price. Portland updates individual properties when permits are pulled for renovations or new construction, but most homes keep the value assigned during the last city-wide revaluation. The last full revaluation was in 2021, and the Council has recommended revaluing every five years going forward.
Exemptions That Reduce Your Taxable Value
Several state-mandated exemptions lower the assessed value the mil rate is applied to. You apply through Portland’s City Assessor’s Office, and most applications are due by April 1.
Homestead Exemption
Maine’s homestead exemption removes $25,000 from the assessed value of your primary residence. You must have owned a home in Maine for at least 12 months before April 1 of the tax year, and the property must be your permanent residence. The $25,000 is a $10,000 base plus a $15,000 additional reduction that took full effect for tax years beginning on or after April 1, 2020. File once, and the exemption continues as long as you occupy the home.
Veteran Exemption
Veterans who served during a federally recognized war period qualify for a $6,000 reduction in assessed value if they are at least 62 years old or receive a federal pension or compensation for total disability. You’ll need your DD-214 or a VA benefit summary letter. Veterans who received a federal grant for specially adapted housing qualify for a larger exemption of up to $50,000.
Blind Exemption
Residents who are legally blind qualify for a $4,000 reduction. You’ll need certification from a licensed physician, osteopath, or optometrist.
Solar Energy Equipment Exemption
Solar panels and related equipment that generate heat or electricity are exempt from property tax in Maine. For tax years beginning on or after April 1, 2025, qualifying equipment includes systems where the energy is used on-site, or where the equipment is collocated with a net energy billing customer subscribed to at least 50% of the system’s output. File a report with the assessor on or before April 1 of the first year you claim the exemption.
When Bills Are Due
Portland’s fiscal year runs July 1 through June 30. FY26 bills were mailed in September 2025 and split into two equal installments. The first installment is due October 17, 2025, and the second is due March 20, 2026. The city accepts payment through its online portal, by mail, or in person at City Hall.
What Happens If You Pay Late
Interest begins accruing the day after an installment due date. For tax year 2026, the maximum interest rate a Maine municipality can charge on delinquent property taxes is 7%, down from the prior year’s 7.5% cap. The State Treasurer sets the ceiling annually based on the prime rate plus three percentage points, and each municipality votes its own rate within that limit.
If taxes stay unpaid, the city can file a tax lien certificate with the Cumberland County Registry of Deeds. Once filed, you have 18 months to pay the overdue taxes, interest, and costs. If you don’t, the lien is automatically deemed foreclosed and the city takes ownership of the property.
If You Think Your Assessment Is Too High
You can file an abatement application with Portland’s assessor if you believe your assessed value is wrong. The deadline is 185 days from the date the city commits its tax roll, which falls around late February 2026 for FY26. The application must be in writing and explain why the assessment is incorrect.
Strong requests include concrete evidence: recent sale prices of comparable homes, a professional appraisal, or documentation of conditions the assessor may not have accounted for, such as structural damage or environmental issues. Disagreement alone isn’t enough. The assessors can also correct errors on their own initiative within one year of commitment. Separately, Maine law lets municipal officers abate taxes for homeowners facing genuine hardship or poverty, with applications accepted up to three years after commitment.
State Programs That Can Help
Maine offers a refundable Property Tax Fairness Credit for residents whose property taxes or rent are high relative to their income. You claim it on your state income tax return, not through the city. For the 2025 tax year, the maximum credit is $1,000 for residents under 65 and $2,000 for those 65 and older. Income limits vary by filing status: single filers generally must earn under $63,750, and married couples filing jointly have a higher threshold. Married couples filing separately cannot claim the credit. The legislature expanded the credit amounts in the 2026 supplemental budget, so the 2026 maximums may be higher. Confirm current figures with Maine Revenue Services when you file.
Maine also runs a deferral program that lets eligible homeowners postpone property tax payments on a primary residence. The deferred amount becomes a lien repaid when the home is sold or transferred. The application window for the 2026 tax year runs from January 1 through April 1, 2026. Eligibility details are in Maine Revenue Services Bulletin No. 34.
