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. Under the updated graduated structure, a $3M sale falls into the 2.5% bracket. This rate applies to the entire purchase price.
The calculation is straightforward: $3,000,000 × 2.50% = $75,000. This fee is part of the New Jersey Realty Transfer Fee and, as of July 2025, is paid by the seller at closing.

New Jersey Mansion Tax FAQ
What is the NJ Mansion Tax?
The New Jersey "mansion tax" is a graduated percentage 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. Under the new 2025 laws, rates range from 1% up to 3.5% based on the total sale price.
Who pays the NJ Mansion Tax — the buyer or the seller?
Historically paid by the buyer, a sweeping legislative change effective July 2025 shifted the New Jersey Mansion Tax liability entirely to the seller. This is paid in addition to the standard Realty Transfer Fee.
How does the NJ Mansion Tax compare to New York's?
Both New York and New Jersey use progressive bracket systems, but with different structures. New Jersey's rates now range from 1% to 3.5%, applying the corresponding rate to the entire purchase price once the threshold is met, and is paid by the seller at closing.
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.
