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

Towns that sell online require registration on their own newjerseytaxsale.com subdomain, a deposit of 10% of intended winnings including premiums (minimum $1,000 in most towns; $1.00 in Franklin), paid by ACH before the town's deposit deadline, and full payment of winning bids by wire transfer. Registrants must be U.S. persons or entities that can supply an IRS Form W-9. There is no fee to participate.

Sale format and venue
New Jersey tax sale certificates are sold town by town, so Warren County has no single sale date, platform or list. Bidding starts at 18% interest and drops in 1% steps to 0%, then moves to a premium bid in $100 increments; no interest accrues on the premium. Redemption adds a 2, 4 or 6 percent penalty based on certificate size, and a holder may begin foreclosure after two years. Check each municipality's own notice for its date and terms. RealAuction RealTaxLien (newjerseytaxsale.com, one subdomain per town) in towns that sell online; other towns follow their own published notice.

Warren County tax sale list and auction calendar

For Warren 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.

  1. Get the advertised 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 county office how and when to register; many counties close registration days or weeks before the sale.

  3. Sale day

    Phillipsburg's 2026 deposits are due October 22, 2026. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the county office before you go.

  4. Confirm with the office

    If the list, platform, and notice disagree, use Municipal Tax Collector of each of Warren County's 22 municipalities (the county holds no tax sale) as the source to confirm which parcels are actually offered.

Before you bid in Warren County

  1. Start with the live sale list

    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 require registration on their own newjerseytaxsale.com subdomain, a deposit of 10% of intended winnings including premiums (minimum $1,000 in most towns; $1.00 in Franklin), paid by ACH before the town's deposit deadline, and full payment of winning bids by wire transfer. Registrants must be U.S. persons or entities that can supply an IRS Form W-9. There is no fee to participate.

  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
2 to 6% one-time penalty at redemption, by certificate size, 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.
