Union County tax sales, New Jersey

Verified

Union has a dominant seat and thin publication. Elizabeth is the county's anchor, it has authorized the modern electronic form of sale, and its collector's material states the annual pattern, sale for prior fiscal year delinquent taxes, water and sewer charges. But Elizabeth publishes no 2026 date, and Union Township, Plainfield, Rahway, Linden and Westfield publish no date either. The only buildable 2026 Union calendar entry from official pages is Roselle's December online sale, whose collector page is the fullest single official sale page found in any of the ten New Jersey counties in this study, down to the cost of sale breakdown. Union's honest shape: an anchor city whose sale exists by authorization and pattern but not by published date, inside a 21 town patchwork.

Next sale: No county sale date exists. Next verified date: Roselle Wed Dec 2, 2026 (online, 9:00 a.m.). Elizabeth authorized an electronic sale for 2026 but publishes no date. Roselle's annual sale is Wednesday, December 2, 2026 at 9:00 a.m. online at roselle.newjerseytaxsale.com, for 2025 and prior delinquent taxes and municipal charges, with the listing and bidding instructions viewable free of charge from November 2, 2026. Elizabeth's electronic sale authorization is a January 27, 2026 council resolution; the sale date itself is not published.

As of November 9, 2026, Roselle's online sale on Wednesday, December 2, 2026 is Union's next verified date, and its listing has been viewable since November 2. Elizabeth's authorized electronic sale carries no published date; if it follows the accelerated track it lands late in the year, but that is inference from the authorization, not a published fact, and this page does not present it as one.

Research Union County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Union County, searchable by address, owner, or county, including parcels that never reach a sale list.

How New Jersey tax sales work

• Nobody at the county sells anything. Under NJSA 54:5-19 the tax collector of each municipality sells. Counties in New Jersey assess nothing for this process and run no sale; every date, list, platform and deposit rule on these pages belongs to a town, not to the county named at the top.
• What is sold is a certificate, a lien, not the property. The Division of Local Government Services states it plainly: at the tax sale, title to the delinquent property itself is not sold; what is sold is a tax sale certificate. The owner keeps the property and is not evicted.
• Two sale tracks run on the statute's calendar. A standard sale is held in the fiscal year following the year of delinquency. An accelerated sale reaches charges in arrears on the 11th day of the eleventh month of the fiscal year, conducted no earlier than the last month of that year, which is why December accelerated sales exist. A municipality may run both.
• Bidding is the rate down from eighteen percent, then premium. Under 54:5-32 the lien is struck off to whoever takes the lowest rate of interest, never above 18 percent. When a bidder offers less than 1 percent or no interest, premium bidding takes over: the winner pays the amount due plus the highest premium. The premium goes to the municipality, earns no interest, is returned if the owner redeems, and escheats to the municipality if the certificate is neither redeemed nor foreclosed within five years.
• Redemption runs through the collector until a court bars it. The owner, heirs, a prior certificate holder, a mortgagee or an occupant may redeem at any time until the right is barred by a Superior Court judgment (54:5-54, 54:5-86), paying the sale amount with interest at the bid rate, the holder's subsequent lien payments and expenses, and the tiered penalty in 54:5-61: 2 percent over 200 dollars, 4 percent over 5,000, 6 percent over 10,000.
• Foreclosure has two clocks, and assignment moves you to the faster one. A private holder may file in Superior Court after two years from the sale; a municipality, or its assignee or transferee, may file after six months (54:5-86), and a municipality may proceed in rem where six months have run and 21 months of general land taxes remain unpaid (54:5-104.32, 54:5-104.34). Since July 10, 2024, P.L.2024, c.39 has revised the process so an owner can protect remaining equity, so foreclosure is no longer the automatic equity transfer older guides describe.
• Unsold liens are struck off to the municipality at eighteen percent. The municipality may later sell those certificates by private assignment under 54:5-113, for not less than the liens by governing body resolution, or at public sale under 54:5-114.1 and 54:5-114.2, the second permitting sales below the amount due. That assignment market is New Jersey's leftover channel, and it is municipal, never county run.

How buying works in Union County

Roselle's model: registration and bidding on the town's RealAuction site, with the listing and instructions live about a month before the sale, Form W-9, United States persons only. Elizabeth's registration terms for its authorized electronic sale are not published.

• The rate is a giveaway on any lien worth having. On contested certificates the interest rate is bid to zero in the first minutes and the real bidding is the premium, which earns nothing and sits with the municipality for up to five years. The disciplined New Jersey bid is therefore set entirely by the property and the foreclosure timeline, never by the rate, and any model that shows yield on a premium dollar is wrong on its face.
• The calendar is the research. New Jersey has no sale season to plan around, only 566 municipal calendars that happen to overlap. The buyers who work this state keep a per town diary: which collector publishes a list, when the town's sale fell last year, whether it sells online or in the room. Each county page in this set is that diary's starting page, honest about which towns publish and which must be telephoned.

Terms: what a bid actually costs

The leftover channel: struck off certificates and municipal assignment

A parcel with no purchaser is struck off to its municipality at 18 percent. The municipality may later sell those certificates by private assignment under 54:5-113 or at public sale under 54:5-114.1 and 54:5-114.2, with the assignee inheriting the six month municipal foreclosure clock under 54:5-86. No Union municipality published a 2026 assignment sale in the pages read, so the channel is stated as law, not as a dated event.

Before you bid

• Start with the town, because there is no county list. Every fact that matters, the date, the list, the platform, the deposit, lives with one municipal tax collector. The county page tells you which towns publish and what they published; the towns that publish nothing are a telephone call, and no website, this one included, can substitute for it.
• Redeem and pay only through the collector. Redemption money goes to the tax collector for the holder's use, and the collector's figure is the redemption figure. Never pay a certificate holder directly on their own number, and record your certificate with the county clerk within 90 days of the sale to protect the lien.
• Know which clock your seller gives you. A certificate bought at the sale carries a two year wait before foreclosure; the same certificate bought by assignment from the municipality can be foreclosed on the six month municipal clock from the original sale date. The channel you buy through is a term of the deal, priced like one.
• Set the maximum before the sale opens. The free Max-Bid Calculator below works backwards from your exit value to the highest bid you can pay, with the costs shown. In premium territory the maximum is a property decision, not a yield decision.
