How Montgomery County sells delinquent taxes

No tax lien certificate sale

under Article 11. The county or other tax district keeps the delinquent tax lien and enforces it itself; no tax lien certificate is sold to individual investors. RPTL 1190 lets a tax district contract to sell liens in bulk to the state Municipal Bond Bank Agency or one of its tax lien entities, which is a negotiated contract with a state agency, not an investor sale. New York City (Bronx, Kings, New York, Queens and Richmond counties) sells tax liens under N.Y.C. Admin. Code 11-319 only to a single authorized buyer, a trust, and not to the general public. Nassau County is the notable exception: it enforces taxes under its own county administrative code and its Treasurer sells tax liens at a public online auction each February.

Sale format and venue
Montgomery County forecloses delinquent parcels in rem under RPTL Article 11 and sells the county-owned parcels at a public auction to the highest bidder. The county has used Collar City Auctions (518-895-8150) as its auctioneer; recent sales run online as timed auctions with bids placed at max bid and a 120-second auto-extend. The County Legislature votes to accept the winning bids, and the Treasurer then executes a quitclaim deed to each successful bidder. A bidder who fails to meet the auction terms forfeits the initial deposit and the property, and the county may offer it to the recorded second bidder. Properties are sold as is; drive-by preview only, and do not enter any property. The county does not post the sale list on its own website; the parcel list appears in the auction catalog when the sale is announced.

Montgomery County tax sale list and auction calendar

For Montgomery County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county 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.

  1. Get the advertised list

    Use Collar City Auctions catalog (county parcel list posted with each auction) for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    Held once a year in summer. Bidding runs on County site; check posted sale dates, registration status, and bidding windows there.
  4. Confirm with the office

    If the list, platform, and notice disagree, use Montgomery County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Montgomery County

  1. Start with the live sale list

    Pull the current advertised parcels from Collar City Auctions catalog (county parcel list posted with each auction). Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    Bidders create a free member account on Collar City Auctions, then register for the specific auction and accept its Terms and Conditions to be approved for online bidding. For the 2023 Montgomery County sale, every bidder had to submit the Bidder Application documents plus a $1,000 credit card hold, returned after the auction. Tax-exempt buyers must file NYS Form ST-120 with the auction company before bidding closes.

  3. Check the state rules that change the bid

    Read the New York due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in New York before you price the title work.
  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

Over-the-counter (leftover) purchases

New York counties keep no statewide over-the-counter list. A county may sell a parcel left unsold at auction by negotiated or sealed-bid sale, but any sale other than a public auction to the highest bidder needs approval by the county's governing body. Whether this county holds any such inventory must be confirmed with the county treasurer.

New York rules

Redemption
In Article 11 jurisdictions redemption runs before the public ever buys. The owner or anyone with an interest can redeem by paying the enforcing officer the delinquent tax liens plus all charges, until the redemption period expires: two years after the lien date by default, or a later date if the published notice of foreclosure names one. A tax district may by local law extend the period for residential or farm property to three or four years, and for residential property of certain deployed military members to four or five years, or shorten it to one year for residential property found vacant and abandoned and placed on a municipal roll. When one tax district holds several liens on a parcel they are redeemed newest first, and foreclosure continues while the oldest lien is unpaid. Anyone who neither redeems nor answers is barred, and the final judgment extinguishes every equity of redemption, so a buyer at the county's later auction takes property no longer subject to redemption. Suffolk County, which enforces under its own tax act, instead records a tax deed and accepts redemption applications within six months of recording.
Deed deposit
No statewide deposit amount. Deposits, bidder registration deadlines, buyer premiums and accepted payment forms are set in each county's terms of sale or the auction contractor's terms; read them before bidding.
Surplus proceeds
New York returns surplus to the former owner and lienholders. Under RPTL 1196, added by L.2024, c.55, Part BB after Tyler v. Hennepin County, the enforcing officer must determine within 45 days after the sale whether a surplus exists by subtracting the taxes, interest, penalties and charges (including the foreclosure cost allowance in RPTL 1102) from the price paid at a public sale, or from the property's full value where the sale was not public. Any surplus is paid into court with a report, and the former owner is notified within ten days. Under RPTL 1197 anyone with an interest just before the judgment may claim a share, adjudicated as in a mortgage foreclosure under RPAPL Article 13. At a public auction the price paid is accepted as full value, so no claim can be brought that the price was too low. For residential property with no claim from the former homeowner, the proceeding stays open at least three years. Unclaimed surplus goes to the tax district to reduce its levy. The buyer's price is not reduced by any of this.
Governing statute
RPTL Article 11 (1100 to 1197)

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
