Maine tax sales by city and town

Verified

Maine collects delinquent real estate taxes through its municipalities, and the mechanism has two halves that buyers often confuse. First, the lien is enforced by a tax lien mortgage: the collector demands payment, records a certificate in the registry of deeds, and if the mortgage is not paid within 18 months after filing, it is deemed foreclosed, with no sale and no court order. Second, the foreclosed property is sold under section 943-C, the post Tyler provision that has governed every sale since August 9, 2024: the municipality must give the former owner at least 90 days notice, list the property with a licensed broker who holds no municipal office, convey it by quitclaim deed at the highest price obtainable within 12 months, and pay the former owner all proceeds above seven statutory deductions. The ten pages below track Maine's largest municipalities, the channel each one actually uses, and the most recent sale each one has officially published.

The local variation sits on top of that fixed frame. Bangor and Lewiston sell through their city realtors with the council approving each disposition by order, Augusta runs a broker programme that sold fifteen properties in 2025, Brunswick authorised its first broker dispositions in September 2026, and several cities publish no tax-acquired sale at all, which their records say plainly. Delinquency interest is local too, set by each municipality under section 505 and capped by the Treasurer of State, and there is no statewide bidder registration, earnest money rule, or closing window. Read the state frame first, then the page for the municipality that holds the parcel.

Verify before you go: a city or town can move a date, change terms, cancel a sale, or pull parcels at any time. The official sale list is the final word.

Each row links to that jurisdiction's own page: selling office, venue or platform, deposit, payment terms, leftover channel, and sources. Where a jurisdiction has not posted a dated sale, the row says so instead of projecting a pattern onto it.

How Maine tax lien mortgages work

• Maine has no county tax sales and no lien auction. Each municipality enforces its own taxes under Title 36, chapter 105, subchapter 9: the tax collector files the lien certificate, the municipal treasurer gives the foreclosure notice, and the municipal officers sell the tax-acquired property under section 943-C.
• Taxes are a lien on the real estate under section 552, taking precedence over all other claims, until the taxes are paid or the lien is otherwise terminated by law. Delinquency interest is set by municipal vote under section 505, subsection 4, capped by the Treasurer of State formula; the cap for taxable year 2026 is 7.00 percent, and there is no single statewide rate.
• After 8 months and within 1 year after the original commitment, the collector demands payment within 30 days, by delivery, leaving at the last and usual place of abode, or certified mail, return receipt requested, with 3 dollars for making the demand plus the certified mail fee (section 942). After the 30 days expire, and within 10 days thereafter, the collector records a tax lien certificate in the registry of deeds, files a true copy with the municipal treasurer, and sends true copies by certified mail to each record mortgage holder and, if the real estate is not assessed to its record owner, to the record owner.
• Filing the certificate creates a tax lien mortgage to the municipality, with priority over all other mortgages, liens, attachments, and encumbrances, but no right of possession until the right of redemption expires (section 943). If the tax, interest, and costs are paid within 18 months after filing, the treasurer or assignee prepares and records a discharge.
• If the mortgage is not paid within 18 months after filing, it is deemed foreclosed and the right of redemption expires, with no sale and no court order. The municipal treasurer must notify the party named on the mortgage and each record mortgage holder, not more than 45 days nor less than 30 days before the foreclosing date, by delivery or certified mail, return receipt requested, stating the exact foreclosure date. A person who did not receive that notice in time may redeem until 30 days after the treasurer does provide it, and a mortgagee or record owner who never received the section 942 notice may redeem within 3 months after receiving actual knowledge of the recording.
• After foreclosure, if the municipality sells to anyone other than the former owner, it must use the section 943-C process: at least 90 days before listing, written notice to the former owner's last known address by certified mail, return receipt requested, and first class mail; listing at the highest reasonable anticipated price with a real estate broker or agent licensed under Title 32, chapter 114, who holds no municipal office and is not employed by the municipality; and conveyance by quitclaim deed at the highest price obtainable within 12 months after listing.
• The former owner receives all sale proceeds above seven deductions: all taxes owed, all taxes that would have been assessed while the municipality owned the property, all accrued interest, the listed fees including broker fees, other selling, maintaining, or improving expenses including documented administrative costs and reasonable attorney fees, the cost of the lien and foreclosure process including reasonable attorney fees, and unpaid sewer, water, or other utility charges and reasonable municipal fees. The municipality must provide a written accounting itemising those deductions at the former owner's request, and must give at least 30 days notice of intent to pay before disbursing the excess.
• If the former owner cannot be located after reasonable diligence, the municipality publishes notice once a week for 3 consecutive weeks in a newspaper of general circulation in the county; if the excess goes unclaimed for 30 days after the final published notice, it is transferred to the Unclaimed Property Fund under Title 33, section 2141. Within 10 days of paying any excess, the municipality records a notice of payment in the registry of deeds, and receipt of the excess waives any action under section 946-B challenging the taking, while preserving a damages action over the conveyance or the amount.
• Only if, after 3 attempts, the municipality cannot contract with a broker or agent, or the broker or agent cannot sell within 12 months after listing, may the municipal officers sell in any manner authorised by the municipality's legislative body, and the excess duty to the former owner still applies (section 943-C, subsection 4-A). If the municipality retains the property for municipal use, it must procure a licensed appraisal and pay the excess on the appraised value (subsection 7). A person may not challenge the validity of the taking after 5 years following the expiration of the redemption period for a lien recorded after October 13, 2014, or 2 years for commercial real estate liens recorded after June 30, 2026 (section 946-B).

Maine forecloses a tax lien mortgage automatically 18 months after the certificate is filed, then sells the property through a licensed broker and pays the former owner all proceeds above seven statutory deductions.

Research the parcels before you bid

A sale list gives you the parcel, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across the country, searchable by address, owner, or county, including parcels that never reach a sale list.
