NJ Mansion Tax 2026: What Sellers of $1M+ Homes Need to Know
If you own a home in Rumson, Spring Lake, Bay Head, Mantoloking, Holmdel or anywhere else in Ocean and Monmouth County where values have crossed $1 million, New Jersey's 2025 change to the "mansion tax" directly affects your bottom line. The tax used to be the buyer's problem. Now it is the seller's, and the rate climbs in steps above $2 million. Here is how it works and how to plan around it.
What changed in 2025
The state budget signed on June 30, 2025 rewrote the mansion tax in two big ways:
- Who pays: the seller now pays it. Before, the buyer did.
- How much: the old flat 1% became a graduated schedule that tops out at 3.5%.
The new rules generally apply to contracts entered into on or after July 10, 2025. The mansion tax is charged in addition to New Jersey's regular Realty Transfer Fee, which sellers already pay.
The 2026 mansion tax rates
| Sale price | Rate | Example tax |
|---|---|---|
| $1,000,000.01 to $2,000,000 | 1% | $1,500,000 sale: $15,000 |
| $2,000,000.01 to $2,500,000 | 2% | $2,200,000 sale: $44,000 |
| $2,500,000.01 to $3,000,000 | 2.5% | $2,800,000 sale: $70,000 |
| $3,000,000.01 to $3,500,000 | 3% | $3,200,000 sale: $96,000 |
| Over $3,500,000 | 3.5% | $4,000,000 sale: $140,000 |
The "cliff": why pricing just over a threshold can cost you
The rate applies to the entire sale price, not just the portion above each threshold. That creates sharp jumps:
- A home that sells for $2,000,000 owes $20,000 (1%).
- A home that sells for $2,020,000 owes $40,400 (2%).
That extra $20,000 in price costs the seller about $20,400 more in tax, so the seller nets less. The same pattern repeats at $2.5 million, $3 million and $3.5 million. These "dead zones" just above each threshold are a big reason pricing strategy matters more than ever in the luxury market.
How sellers can plan for it
- Run your net sheet early. (Our New Jersey seller cost guide covers every line item.) Before you pick a list price, look at your estimated proceeds at several price points, including mansion tax, Realty Transfer Fee, commission, attorney fees and mortgage payoff.
- Price with the thresholds in mind. Sometimes listing just under a threshold attracts more buyers and nets the same or more. Other times the market clearly supports a price well above it. Your agent should show you the math both ways.
- Negotiate with your net in mind. When an offer lands just over a threshold, compare it against a slightly lower offer on a net basis, not headline price.
- Be careful with personal property. Furniture, boats or other items sold with the home must be handled properly in the contract. Ask your attorney before trying to allocate value away from the real estate.
- Talk to your attorney and tax advisor. Exemptions are narrow, and capital gains and, for nonresident sellers, New Jersey's estimated gross income tax payment at closing can also affect your proceeds.
What about buyers?
For buyers of $1 million-plus homes, the change is good news: the mansion tax is no longer on your side of the closing statement. Sellers may try to factor the new cost into their pricing, so expect some negotiating around those threshold price points.
Frequently asked questions
Who pays the mansion tax in New Jersey in 2026?
The seller, for contracts entered into on or after July 10, 2025.
Is the mansion tax the same as the Realty Transfer Fee?
No. The Realty Transfer Fee applies to most sales at any price and is paid by the seller. The mansion tax is an additional charge on sales over $1 million.
Does the higher rate apply only to the amount over $2 million?
No. The rate applies to the full sale price, which is why sales just above a threshold can cost noticeably more.
