Knox County tax sale list and auction calendar
For Knox County tax sale 2026 searches, use the city and town sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the collector of the city or town holding the sale before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.
Confirm the advertised parcel list
Use State of Maine, Unorganized Territory: tax-acquired listings by Maine Revenue Services' broker, On Point Realty (statewide, not a county list) as a starting reference. Check which sale or list it covers; a Lands Available or office information page is separate from an auction parcel list. Ask the sale office for the advertised parcels for the auction you plan to attend.Register to bid

Maine rules
- Redemption
- The owner, or anyone with an interest, may pay the tax, interest and costs at any time within 18 months after the lien certificate is filed in the registry of deeds. 30 to 45 days before the foreclosure date the treasurer must notify the owner named on the lien and each record mortgage holder; anyone not given timely notice may redeem until 30 days after the notice is actually given. After foreclosure there is no right to redeem, although the municipality may choose to sell or convey the property back to the former owner, and the former owner is paid any excess when the property is sold.
- Deed deposit
- No statutory deposit. A broker sale follows ordinary purchase-and-sale terms the municipality negotiates; where a municipality sells by its own method after a failed listing, its legislative body's authorization and published terms set any deposit.
- Surplus proceeds
- The former owner (the owner of record at foreclosure, or heirs, devisees or personal representatives) receives the sale proceeds above: all taxes owed; the taxes that would have been assessed while the municipality owned it; accrued interest; advertising, mailing, recording, listing and broker fees not covered by the broker agreement; other costs of selling, maintaining or improving the property, including documented administrative costs and reasonable attorney's fees; the cost of the lien and foreclosure process; and unpaid sewer, water or other utility charges and municipal fees. The former owner may request an itemized accounting. The municipality mails notice at least 30 days before paying, publishes notice for 3 weeks if the owner cannot be found, and sends unclaimed proceeds to the Unclaimed Property Fund 30 days after the last notice. If the municipality keeps the property, it pays the excess using an independent licensed appraisal instead of a sale price. Accepting the excess waives the former owner's right to challenge the taking.
What the deed conveys: Quitclaim only, with no warranty. A challenge to the validity of the tax taking may be brought for 5 years after the redemption period expires (liens recorded after October 13, 2014), 2 years for commercial real estate on liens recorded after June 30, 2026, and only 6 months after a code enforcement officer certifies residential tax-acquired property abandoned (liens recorded after December 1, 2021). The former owner's receipt of excess proceeds waives that challenge. A former owner or mortgagee who was not given the required notices may have a late redemption right (see redemption). Budget for a title search and, where a title insurer requires it, a quiet-title action under 946. See the due diligence guide.
