St. Lawrence County tax sale, 2026 season

Verified

St. Lawrence County (county seat Canton) sells its tax foreclosed real estate online only through Auctions International, on the StLawCoAuction.com sale site, for the St. Lawrence County Treasurer. The 2026 auction opened Saturday, September 12, 2026 and lots started closing Saturday, September 26, 2026. County local law sets the auction on the second Saturday in September in an auction year, and the 2026 sale followed it exactly.

The gate in this county is paper, not clicks: an original, signed bidder registration packet had to be received by the auctioneer by 4:00 PM on Thursday, September 24, 2026, in the middle of the bidding window, with no exceptions. Mailed packets carrying a credit card authorization, the Offer to Purchase page, or the photo ID page had to be notarized. If you search for a St. Lawrence County tax auction, this is the sale, and its terms were among the most complete any New York county published this year.

Research St. Lawrence County parcels before you bid

A sale list gives you the parcels, 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 St. Lawrence County, searchable by address, owner, or county, including parcels that never reach a sale list.

How New York tax foreclosure works

Unpaid taxes become a lien on the property, and the county enforces that lien in court under Real Property Tax Law Article 11, the in rem foreclosure process.
The owner gets a redemption period, two years from the lien date by default, longer where a local law extends it for homes or farms. Paying everything owed during that window ends the case.
When the period expires, the court can award the property to the county. The former owner's right to redeem is over at that point; there is no post-sale redemption period on a New York tax deed.
The county then sells at public auction, which is the sale this page tracks. Deeds are usually quitclaim, bids can require county legislature approval, and any surplus over the taxes and charges is handled under RPTL sections 1195 to 1197 for the former owner and lienholders.

How registration works

Two steps, both mandatory. First, create an Auctions International account; the 2026 packet's promo code STLAW26 waived the one time registration fee. Second, deliver the original signed bidder registration packet to Auctions International, 11167 Big Tree Road, East Aurora, NY, so it is received by 4:00 PM on September 24, 2026. Received means in hand, not postmarked.

Notarization: the credit card authorization, Offer to Purchase signature page, and photo ID page must be notarized if mailed.
Entities must provide the state filing receipt, the EIN, and a corporate resolution.
Delinquent bidders are barred: anyone delinquent on St. Lawrence County taxes from a prior year cannot bid, including through an agent.

Terms: what a bid actually costs

The money layer, from the official 2026 terms. The deposit is calculated on the high bid plus the premium, and the recording fee is a separate check to a different office.

Deposit	The greater of $50 or 20 percent of the high bid, plus the buyer premium, due by Monday, October 5, 2026 on execution of the Offer to Purchase. Paid by credit card (Visa, Mastercard, Discover), cash, money order, or guaranteed funds payable to SLC Treasurer. Card chargebacks are barred by the terms; a chargeback the county or auctioneer has to fight carries a $750 recovery fee.
Buyer premium	8.77 percent of the bid when paid by credit card; 6 percent when paid by cash or certified funds.
Recording fees	Paid by separate check to the St. Lawrence County Clerk: $185 for residential (class 200s) and agricultural (class 100s) parcels; $310 for all other parcels. The buyer also pays prorated current taxes, water, and sewer charges as of the recording date.
Balance due	The entire balance of the purchase price, plus premium and recording fees, by 4:00 PM on Monday, October 26, 2026, in cash or a certified bank check payable to the St. Lawrence County Treasurer. Miss it and the bid is rejected and the deposit is kept as liquidated damages; the county may take the next highest bid or resell.
Deed type	Quitclaim deed only, with the description as it appears on the tax roll for the year the county acquired title. The County Treasurer records the deed after full payment; title passes on recording and possession before recording is forbidden.

What happens to parcels that do not sell

On a buyer default, the county may accept the next highest bid or resell the parcel. For parcels that stay unsold, county local law allows a properly advertised private sale, and private sales require approval by the Board of Legislators. There is no standing over the counter list published in the sources checked; watch the Treasurer's postings after each auction.

Before you bid

Two eligibility rules in this county are stricter than most. Former owners and their agents are strictly barred from bidding, and a buyer may not convey a parcel back to its former owner within 10 years of the auction date. The deed can only name registered bidders: no assignments. The terms also warn that parcels sell subject to federal and state taxes, liens, and judgments of record, which is broader survival language than most counties use. There is no post-sale redemption: under Article 11 the redemption period ended before the foreclosure judgment. Verify before you go: the terms themselves state they may change by court order.
