If you are buying or selling a luxury home in New Jersey, you need to factor the state's "Mansion Tax" into your bottom line. While this tax has been around since 2004, sweeping legislative changes that took effect in July 2025 completely shifted how it works and who pays it.
Here is a breakdown of what the Mansion Tax is, how the tiered rates work, and what it means for your next real estate transaction.
What is the NJ Mansion Tax?
The New Jersey Mansion Tax is a supplemental fee applied to the sale of residential properties—and certain commercial properties—that sell for $1 million or more.
A common misconception is that the tax only applies to the amount above $1 million. In reality, if your transaction crosses the $1 million threshold, the tax is calculated on the entire purchase price.
The 2025 Shift: Sellers Now Foot the Bill
For nearly two decades, the Mansion Tax was a flat 1% fee paid by the buyer at closing. That changed dramatically for contracts signed on or after July 10, 2025. The responsibility for paying the Mansion Tax shifted entirely from the buyer to the seller.
In addition to shifting the financial burden, the state replaced the flat 1% rate with a tiered, graduated structure for properties over $2 million.
Current Mansion Tax Rates
If your home sells for under $1 million, you are completely exempt from this specific tax. For sales at or above $1 million, the seller must pay a percentage of the total sale price based on the following tiers:
Sale Price Range | Tax Rate | Who Pays |
$1,000,000 to $2,000,000 | 1% | Seller |
$2,000,001 to $2,500,000 | 2% | Seller |
$2,500,001 to $3,000,000 | 2.5% | Seller |
$3,000,001 to $3,500,000 | 3% | Seller |
Over $3,500,000 | 3.5% | Seller |
Because these are "cliff" brackets, crossing a threshold significantly impacts your net profit. Selling a home for $1,999,000 incurs a 1% tax ($19,990), but selling that same home for $2,001,000 bumps the entire price into the 2% bracket, doubling the tax to $40,020.
Navigating luxury real estate requires precision. Whether you are looking to list your property or searching for your next home, having a strategic partner ensures you are making the smartest financial decisions.
