How Jefferson 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.

The parcel list is posted on Brzostek's site before each auction; the county's own auction page links to it once the new list is up.

Jefferson County tax sale list and auction calendar

For Jefferson 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 2026 auction parcel list (Brzostek) 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 June. 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 Jefferson County Attorney's Office, Tax Enforcement (Tax Enforcement Officer), with the online auction conducted by Brzostek's Real Estate Auction Co. as the source to confirm which parcels are actually offered.

Before you bid in Jefferson County

  1. Start with the live sale list

    Pull the current advertised parcels from 2026 auction parcel list (Brzostek). Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    Register online at brzostek.com during the pre-bidding session and follow the Proxibid registration steps. There is no in-person auction. At the strike, the buyer pays by credit card 25% of the price or $1,000, whichever is greater (the full bid if under $1,000), plus a 10% buyer's premium, a $500 administrative fee per parcel and transfer tax; the credit card charge is capped at $10,000, with any remaining deposit due to the Jefferson County Treasurer within three days. The balance is due within 30 days by cash or certified funds payable to the Jefferson County Treasurer. Anyone delinquent on other Jefferson County property taxes, or who defaulted at a county tax auction within three years, may not bid.

  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.

County notes

  • Jefferson County sells tax-foreclosed parcels once a year at an online auction conducted by Brzostek's Real Estate Auction Co. The county lists the next auction as tentatively June 2027.
  • Winning bidders receive a bidder certification and purchase contract by e-signature within 72 hours. The county records the quitclaim deed after full payment and closing. Buyers should not enter or occupy the property until the deed is recorded.
  • The county runs a delinquent tax installment program: an owner who pays 25% down and the rest in eight installments over two years, while keeping new taxes current, avoids foreclosure. Parcels in that program do not reach the auction.

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.
