How Warren County sells delinquent taxes

From lien to deed

New Jersey holds no tax deed auction. A certificate holder who is not redeemed files an action in the Superior Court to foreclose the right of redemption: a private purchaser at any time after two years from the sale, the municipality (or anyone who takes the certificate from it by assignment or transfer) after six months, and any holder at any time if the property meets the statutory definition of abandoned property. Judgment bars redemption and vests title in the holder. Since P.L.2024, c.39 the owner or the owner's heirs may, before final judgment, demand that the foreclosure proceed by a sheriff's sale or a sheriff's Internet auction to preserve equity; that sale is run by the county sheriff and is a foreclosure sale of one parcel, not a tax sale, so a sheriff's sale listing is never the date of a municipality's certificate sale. Separately, a municipality holding its own certificates may foreclose by an in rem action once more than six months have passed since the sale and 21 months of taxes are unpaid.

Registration and deposit

Sale format and venue
Warren County holds no tax sale; each of its 22 municipalities sells its own certificates, so there is no single county date, platform or list. Bidding starts at 18 percent interest and is bid down; under N.J.S.A. 54:5-32, once a bid falls below 1 percent, bidders offer a cash premium instead, and the premium earns no interest. The RealAuction town sites (one newjerseytaxsale.com site per town) take rate bids in 1 percent steps, so on those sites the premium stage starts at 0 percent, with premiums in $100 steps. Towns that do not sell online follow their own published notice.

Warren County tax sale list and auction calendar

For Warren 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.

  1. Confirm the advertised parcel list

    Each city or town sells separately and posts its own list. The municipal notes on this page say where each one appears.

  2. Register to bid

    Ask the collector of the city or town holding the sale how and when to register; many close registration days or weeks before the sale.

  3. Sale day

    Each city or town picks its own platform or in-person venue. Confirm the date and registration window with that town’s collector before you bid.

  4. Confirm with the office

    If the list, platform, and notice disagree, treat the collector of the city or town holding the sale as the source for which parcels are actually offered. Do not rely on a third-party list for final parcel status.

Before you bid in Warren County

  1. Confirm the parcel list before pricing

    There is no county list: each town posts its own. Get the list from the town whose sale you plan to attend and confirm the advertised parcels with its collector before you price a bid.

  2. Confirm registration and deposit

    Towns that sell online, such as Oxford, take registration on their own newjerseytaxsale.com site and require a deposit of 10% of intended winnings including premiums ($1,000 minimum at Oxford), paid by ACH before the town's deposit deadline, with full payment of winning bids by wire transfer.

  3. Check the state rules that change the bid

    Read the New Jersey due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.

  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

Certificates on parcels that drew no bid are struck off to the municipality at 18 percent. A municipality's governing body may later sell a certificate it holds by assignment or at a separate public sale, at its discretion. Ask the tax collector of the specific municipality.

New Jersey rules

Max interest rate
18% per year, bid down at auction
Minimum return
One-time penalty at redemption by certificate amount (2% over $200, 4% over $5,000, 6% over $10,000), added to the interest
Redemption
The right to redeem lasts until it is cut off by a foreclosure judgment, not for a fixed term. What varies by parcel is how soon the holder may start that action: two years after the sale for a private purchaser, six months for the municipality or its assignee, and any time for abandoned property. Once a foreclosure complaint is filed and notice of it is filed with the tax collector, redemption is made in that court action and carries the court-fixed attorney's fees and costs. All other redemptions must go through the municipal tax collector's office; a lienholder who knowingly takes a redemption outside that office forfeits the certificate.
Surplus proceeds
Surplus arises only from a sheriff's sale or Internet auction demanded by the owner under N.J.S.A. 54:5-87(b). The sheriff deducts the cost of the sale and deposits the surplus with the Clerk of the Superior Court, and the owner or heirs claim it by motion under N.J.S.2A:50-37 and the Rules of Court; that is the exclusive route. If the owner does not demand a sale, the holder may foreclose without one and the owner has no claim against the holder for any equity. In an abandoned-property foreclosure the court may bar claims to surplus equity and no sheriff's sale is required.
Governing statute
N.J.S.A. Title 54, Chapter 5

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.

Frequently asked questions

Does Warren County, New Jersey sell tax liens or tax deeds?

Tax lien certificates. In New Jersey investors buy the lien, not the property; the Municipal tax collector runs the sale.

When is the Warren County tax certificate sale?

Each municipality sets its own date. The 2026 online sales posted for Warren County towns fall in early to mid October: Harmony on October 2, Franklin on October 5, White on October 9, Washington Borough on October 13 and Oxford on October 14, 2026. Always confirm the exact date with the Municipal tax collector before the sale.

I own a property in this sale. Can I stop it?

Often yes, by paying the overdue taxes, interest, and costs before the deadline. New Jersey's redemption rule: 2 years from the sale before a private certificate holder can file to foreclose; the owner can redeem until the court's final judgment.
