Example: Mansion Tax Calculation for a $3 Million Property in 2026
A property purchased for $3,000,000 in New Jersey exceeds the $1,000,000 threshold, triggering the state's mansion tax. Unlike New York's progressive bracket system, New Jersey applies a single flat rate of 1% on the entire purchase price.
The calculation is simple: $3,000,000 × 1.00% = $30,000. This fee is part of the New Jersey Realty Transfer Fee and is paid by the buyer at closing. Properties purchased for $1,000,000 or less are entirely exempt from this additional fee.

New Jersey Mansion Tax FAQ
What is the NJ Mansion Tax?
The New Jersey "mansion tax" is an additional 1% fee on top of the standard NJ Realty Transfer Fee. It applies to all residential property transactions where the total consideration exceeds $1,000,000. It was enacted to generate revenue from luxury home sales.
Who pays the NJ Mansion Tax — the buyer or the seller?
In New Jersey, the mansion tax is paid by the buyer. This is in addition to the standard Realty Transfer Fee, which is typically the seller's responsibility. The 1% mansion tax is due at closing and is remitted through the county recording office.
How does the NJ Mansion Tax compare to New York's?
New York's mansion tax uses a progressive bracket system with rates ranging from 1% to 3.9% depending on the purchase price. New Jersey's system is much simpler — a single flat rate of 1% on the entire purchase price applies to any property over $1,000,000.
Are there any exemptions?
Properties purchased for $1,000,000 or less are exempt. Certain transfers — such as those between family members, court-ordered transfers, or governmental acquisitions — may also qualify for exemptions under specific NJ statutes.
