Suffolk County, New York — Tax Sale & Surplus Procedure

Local operations layer. The legal framework (redemption periods, surplus rights, statutes, case law) lives on the parent page → new-york. This page covers how Suffolk County actually runs it. Legal information, not legal advice. Last verified: 2026-06-02.

Critical jurisdictional note. Suffolk County does not use the statewide RPTL Article 11 in rem scheme described on new-york. Instead it operates under the Suffolk County Tax Act (New York Laws, ch. 1195; consolidated at Justia SCT), a special county charter law that pre-dates and opts out of RPTL Art. 11. Under the Suffolk County Tax Act, the County Comptroller takes a lien on delinquent parcels at an annual tax lien sale (typically November–December); all bids are rejected and the County of Suffolk itself purchases every lien pursuant to a County Legislature resolution under SCT §§ 45–46. The County then forecloses and, after the redemption period, takes a tax deed. There is no competitive third-party lien investor. Properties that vest in the County and are not redeemed are disposed of via public auction — that auction is the online property sale on RealAuction.com. Suffolk County enacted Local Law No. 25-2024 (effective Oct. 25, 2024) to bring its surplus-distribution process into compliance with Tyler v. Hennepin County (2023) while maintaining opt-out status from RPTL Art. 11. Local Law 25-2024, Resolution 601-2024

Suffolk County Comptroller — Information for Taxpayers Real Property Auction page

  • Two-phase process:

    1. Annual Tax Lien Sale (Comptroller phase) — held each November or December under SCT §§ 40–46. The Comptroller takes a lien on all parcels with unpaid taxes for the current tax year. By County Legislature resolution, all third-party bids are rejected and every lien is purchased by the County of Suffolk itself. There is no public bidding at the lien sale. Authority: SCT § 46 (county may purchase at sale); County Legislature resolution pursuant to SCT §§ 45–46. Taxpayer Information Sheet (PDF)
    2. Annual Real Property Auction (Division of Real Property phase) — properties for which the redemption period has expired and a tax deed has been issued to the County are disposed of by online auction on RealAuction.com, typically held in November or December. The 2024 auction was held November 20, 2024; the 2025 auction was held December 10–11, 2025. 2025 auction announcement

  • Auction platform: RealAuction.com (Realauction.com, LLC), selected by the County in 2024. The 2024 county-hosted GIS viewer for the auction was at https://gisapps.suffolkcountyny.gov/suffolkauction2024/. The bidding itself occurs on the RealAuction.com platform; link to the specific Suffolk County storefront is published on the auction announcement page each year (needs_verification: exact subdomain/storefront URL for the current auction cycle).

  • Sale calendar:

    • Lien sale: annually, November or December (exact date announced via newspaper notice published for 6 weeks in the two designated official newspapers and in one newspaper in each of the 10 towns for 2 weeks prior to sale). 2024/25 lien sale: December 5, 2025 (announced via public notice in Babylon Beacon, Nov. 2025).
    • Property auction: annually, November or December. 2024: November 20; 2025: December 10–11. Registration for the 2025 auction closed December 3, 2025.
    • Delinquent list: published in the official county newspapers for 6 weeks before the lien sale and in one town newspaper for 2 weeks. SCT § 43 requires publication for at least 6 successive weeks in the two officially designated newspapers; parcels in towns where those newspapers are not located are also separately published in a newspaper of that town. SCT § 43 (NYSenate)

  • Registration / deposit — property auction (RealAuction phase):

    • Bidders must complete and upload: a Registration Form, Acknowledgment of Terms, and IRS W-9 form on the RealAuction.com platform.
    • Deposit: 23% of anticipated maximum bid plus a $325 auction vendor fee per property, paid by ACH or wire transfer. needs_verification: the 23% figure comes from search-snippet summaries of press coverage only — it has not been confirmed by reading a live RealAuction platform page or a retrieved county auction-rules document. Verify against the live RealAuction storefront or the current auction announcement before quoting to a client.
    • Telephone help-desk: via RealAuction.com and via Suffolk County 311.
    • A $325 auction fee is paid by the winning bidder. [Source: search-snippet corroboration via Newsday / TBR News reporting on 2024 & 2025 auctions; county auction page not retrieved (HTTP 403)]

  • Rate within statutory range: N/A (Suffolk County Tax Act lien sale; no competitive interest-rate bidding — County takes all liens at the statutory penalty rate: 5% penalty + 1% per month from February 1 of the tax year, per the Comptroller’s taxpayer information sheet).

  • Bidder requirements (property auction): Any legal entity may register; IRS W-9 required; no residency requirement identified. Needs_verification: any disqualifying conditions (outstanding County debt, etc.).

  • Delinquent list location: Published in the two officially designated Suffolk County newspapers for 6 weeks before the lien sale and separately in town-level newspapers. No standing online publication of the annual lien list identified; individual parcel tax status is accessible via the MUNIS self-service portal. Tax payment/inquiry portal

C2. Local Redemption → framework: right-of-redemption

  • Where to redeem: upon application to the Suffolk County Comptroller, 330 Center Drive, Riverhead, NY 11901. Phone: (631) 852-3000. Comptroller contacts

  • Redemption periods (SCT):

    • Non-residential / unimproved: 12 months from the date of the tax lien sale.
    • 1–3 family residential: 36 months from the date of the tax lien sale.
    • Authority: Suffolk County Tax Act §§ 49, 52 (corroborated by Comptroller taxpayer information sheet and multiple lien-sale newspaper notices). SCT § 52 (NYSenate)

  • Redemption amount: amount of the lien + accrued interest + any subsequent taxes due to the County. Penalty: 5% flat + 1%/month from Feb. 1 (June = 5%, July = 6%, Aug = 7%, Sep = 9%, Oct = 10%, Nov = 11%, Dec = 11%). Interest compounds on flat-tax + penalty base. Taxpayer Information Sheet

  • Redemption statements: available upon request to the County Comptroller.

  • Tax deed: issued to the County of Suffolk at the expiration of the 12- or 36-month redemption period, provided no prior redemption has been made.

  • Deviations from RPTL Art. 11 state default: Yes — the statewide 2-year default redemption period does not apply. Suffolk County operates exclusively under the SCT (12/36-month periods). There is no RPTL Art. 11 2-year extension for residential or farm property here.

  • Local fees: 5% penalty + escalating interest schedule (1%/month) as above; tax sale advertising fee added if taxes unpaid after August 31 of the tax year.

C3. Local Surplus / Excess Proceeds → framework: surplus-funds

Key Suffolk-County–specific rule: Suffolk County does not use the RPTL §§ 1196–1197 surplus-claim procedure described on new-york. Surplus claims are administered by the Division of Real Property Acquisition and Management under the Suffolk County Administrative Code Article XL, § A40-4(L), as amended by Local Law No. 25-2024 (Resolution 601-2024, eff. Oct. 25, 2024) and Local Law No. 33-2023 to comply with Tyler v. Hennepin County (2023). Claims are filed administratively with the Division, not in court. Resolution 601-2024 / Local Law 25-2024 (full text)

  • Claim filing venue:

    • Office: Division of Real Property Acquisition and Management, Department of Economic Development and Planning, Suffolk County
    • Address: H. Lee Dennison Building, 100 Veterans Memorial Highway, Hauppauge, NY 11788
    • Phone: (631) 853-5926 (primary — from 2021 county brochure; a 211ny.org directory entry cites (631) 853-5593 for the same office. needs_verification: confirm the correct direct line from the live county page before relying on either number — suffolkcountyny.gov returns HTTP 403 to automated fetches.)
    • URL: Real Property Acquisition and Management
    • Claims are filed in writing with the Division, not in court (unlike the RPTL Art. 11 court-based surplus procedure).

  • Surplus defined (Local Law 25-2024, § A40-4(L)):

    • Auction sale: sale price minus (total taxes owed + interest + penalties + RPTL § 1102 charges).
    • Non-auction disposition: full value per tax roll, or licensed appraisal, or other reasonable valuation — minus taxes/interest/penalties/charges.

  • Who may claim: former owner and any other parties whose interests were extinguished by the foreclosure of the delinquent tax lien (“Applicants”) — including mortgagees, judgment-lienholders, and others with recorded interests.

  • Notice: when surplus is available, the Commissioner or designee shall make reasonable efforts to notify Applicants in writing at their address of record with the Comptroller, address noted in a title report, or other accurate/current address.

  • 90-day publication list: the Commissioner shall publish on the County website for at least 90 days following the County’s disposition of the property a list of parcels for which surplus may be available. The list must include: a link to the County’s surplus application, contact information for a County representative, and each parcel’s street address, Suffolk County Tax Map identification number, and date of recording of the County’s tax deed. Local Law 25-2024 text, § A40-4(L)

  • Unclaimed-surplus list published? Yes — required by Local Law 25-2024 to be published on the County website for ≥90 days post-disposition. Specific URL of the live list: needs_verification (the county auction page is suffolkcountyny.gov/… Real-Property-Auction but the active surplus-list URL was not retrieved from a live fetch).

  • Claim form: written application to the Division; the Commissioner is authorized to promulgate rules governing the form and deadline. Specific form name / PDF URL: needs_verification (not retrieved from a live page fetch).

  • Deadline: set by Commissioner regulations pursuant to § A40-4(L); specific deadline not found in retrieved sources — needs_verification.

  • Distribution priority: equitable, based on interests held immediately prior to foreclosure of the lien (per § A40-4(L)(1)).

  • Contact: Division of Real Property Acquisition and Management, (631) 853-5926 (primary; see phone discrepancy note in Claim filing venue above), H. Lee Dennison Building, 100 Veterans Memorial Highway, Hauppauge, NY 11788.

  • Tyler compliance: reformed_post_Tyler. Local Law 33-2023 amended Article XL to add initial Tyler-compliance provisions; Local Law 25-2024 further updated the surplus definition to match RPTL § 1195 language, ensuring the County retains opt-out status while providing an administrative surplus-claim mechanism. needs_verification (Local Law 33-2023): the existence and content of Local Law 33-2023 is verified only transitively — Resolution 601-2024 (Local Law 25-2024) recites that Local Law 33-2023 made initial Tyler-compliance amendments. The actual text of Local Law 33-2023 has not been retrieved or read directly. Do not cite its specific provisions without first obtaining and reading the enrolled law text.

Note on assessors: There is no county-level assessor in Suffolk County; property assessments are set by the individual town assessors in each of the 10 towns. The Real Property Tax Service Agency oversees assessment administration countywide.

C5. Local Procedure Notes

  • Special charter — opt-out jurisdiction: Suffolk County operates under a special law (SCT) that predates RPTL Article 11 and has been continuously exempted from it. The County Legislature’s annual resolution directs the Comptroller to buy all liens, eliminating any competitive third-party lien investor market. This is the most significant local deviation from the RPTL Art. 11 framework described on new-york.

  • No competitive lien sale: unlike Nassau County or NYC (which sell to trusts), Suffolk County buys all liens itself. Third parties may not purchase tax liens on individual Suffolk County parcels at the annual lien sale.

  • Two-step foreclosure path: after the lien is sold to the County and the redemption period expires, the County Attorney prosecutes all necessary legal work to vest a tax deed in the County (SCT § 46 et seq.; search result corroborated). Only then are deeded parcels placed into the annual RealAuction property auction.

  • Tyler compliance via local law (not RPTL §§ 1196–1197): Suffolk County’s surplus regime is Administrative Code § A40-4(L), not the statewide court-based RPTL surplus proceeding. Claims go to the Division (administratively), not to Supreme Court.

  • Mortgage foreclosure surplus: when a mortgage foreclosure sale in Suffolk County produces surplus (RPAPL Art. 13), those funds are paid into Supreme Court and the Fiduciary Clerk at 1 Court Street handles surplus-money proceedings — separate from the tax-lien surplus process above.

  • Town tax receivers: each town has its own Tax Receiver who collects town, school, and county taxes from December 1 through May 31. After May 31, delinquent taxes transfer to the County Comptroller. Redemption/payment of town taxes before the lien sale must be made to the town’s Tax Receiver, not the Comptroller.

  • Publication required by SCT § 43: notice of sale must be published at least once per week for six successive weeks in the two designated official newspapers, plus for two weeks in a newspaper in each town where affected parcels are located. This is the mechanism for the annual delinquent list — there is no single-URL online delinquent list portal at the county level.

  • Property auction list — 60-day advance publication: the Division of Real Property publishes the list of deeded parcels to be auctioned at least 60 days before the auction date; towns and villages receive mailed copies. The list is available via the county website and the RealAuction.com platform.

  • Land Bank: the Suffolk County Land Bank (suffolkcountylandbank.org) acquires certain tax-delinquent parcels transferred by the County under General Municipal Law § 72-h for community redevelopment purposes. Those parcels do not go through the public auction.

C6. Records Access

Note on deed recording: e-recording is not yet available for Suffolk County Clerk filings as of the last_verified date. Physical recording is required at 310 Center Drive, Riverhead, NY 11901; hours M–F 8:30–4:30.
