Big changes are coming to New Jersey real estate — and if you’re buying or selling a high-value property, this update could impact your bottom line in a major way.
On June 30, 2025, the New Jersey Legislature passed a new state budget, and with it comes a dramatic shift to the so-called “Mansion Tax.” These changes go into effect on July 10, 2025, and apply to all closings that occur on or after that date — regardless of when the property was listed or went under contract.
Whether you’re selling a luxury home, planning to buy over $1 million, or just trying to understand how this affects your long-term plans, this post breaks down what’s happening — and what you can do about it.
🧾 What’s Changing in NJ Real Estate Taxes?
✅ 1. The Mansion Tax Is Now a Seller’s Responsibility
Previously, buyers paid a 1% tax on homes over $1,000,000 in New Jersey.
Starting July 10, 2025, this tax burden will shift from the buyer to the seller for all transactions where the purchase price exceeds $1 million.
Why it matters:
This changes the math dramatically for anyone listing a higher-end home. Sellers now need to budget for this tax as part of their closing costs.
✅ 2. Tiered Tax Rates for Homes Over $2 Million
For homes priced over $2 million, new graduated tax rates will apply. The higher the price, the higher the tax — up to 3.5% at the top tiers.
📊 Example:
- $1.2M home = 1% (seller-paid)
- $2.5M home = Higher tiered rate
- $5M+ home = Up to 3.5% tax
This could represent tens or hundreds of thousands of dollars in additional cost for luxury sellers.
✅ 3. Limited-Time Rebate Opportunity for Sellers
If you’re currently under contract — or close — there’s a small window to potentially qualify for a tax rebate.
⏳ Here’s how:
- Go under contract before July 10, 2025
- Record the deed before November 15, 2025
- Even if eligible for a rebate, you must still pay the new tax upfront
👉 Pro tip: If you’re on the fence about listing or accepting an offer, now’s the time to act.
