What the Mansion Tax Is
The New Jersey mansion tax is a transfer tax imposed on certain real estate transactions when property consideration exceeds $1,000,000. The tax applies to the entire transaction once the threshold is exceeded. It is not limited to the portion above $1,000,000, which is a common misunderstanding.
The mansion tax is embedded in New Jersey law and is applied as part of the real estate transfer process, generally at closing and deed recording. It is closely tied to the property’s classification and the consideration rules defined under state law. Officially, the fee is now called the Graduated Percent Fee.

How Much Is the Mansion Tax? (2025 Rates)
Before July 2025, the mansion tax was a flat 1% of the total price. For deeds recorded on or after July 10, 2025, New Jersey replaced the flat rate with a graduated rate that applies to the entire consideration, not just the amount inside each tier. The current rates are:
| Sale price (total consideration) | Rate on the entire price |
|---|---|
| More than $1,000,000 up to $2,000,000 | 1% |
| More than $2,000,000 up to $2,500,000 | 2% |
| More than $2,500,000 up to $3,000,000 | 2.5% |
| More than $3,000,000 up to $3,500,000 | 3% |
| More than $3,500,000 | 3.5% |
Worked example: on a $2,750,000 sale, the rate is 2.5% applied to the full price. That is 2.5% times $2,750,000, or $68,750, payable by the seller at recording, on top of the standard Realty Transfer Fee. For a more typical sale, a $1,200,000 home sits in the first tier, so the mansion tax is 1% of $1,200,000, or $12,000, again payable by the seller.

Who Pays the Mansion Tax
For deeds recorded on or after July 10, 2025, the seller is statutorily responsible for paying the mansion tax in New Jersey. Before that date, the buyer paid it at closing. Who pays is the most misunderstood part of the rule, and it is the exact point that changed in 2025.
According to April Moore, EA, of Wasserman Accounting, “many clients, real estate agents, and even some professionals are still referencing the older rules” and do not realize how materially the closing cost structure changed.
Because the obligation now sits with the seller by law, the negotiation has flipped. A seller can still try to shift the economic cost back to the buyer through price or concessions, but the legal duty to pay no longer starts with the buyer. How the cost is ultimately split depends on leverage and market conditions.

How the Mansion Tax Is Calculated
Consideration is the entire compensation paid for the transfer of title. It includes the full purchase price plus the remaining balance of any mortgage the buyer assumes, and any other lien or encumbrance left in place at closing. Routine amounts that are simply prorated between buyer and seller, such as current year property taxes, are not counted.
To calculate the mansion tax:
This broader definition of consideration often leads to miscalculations. Many buyers and sellers assume the tax applies only to the contract price but NJ law defines consideration more broadly. As a result, transactions can cross the one million threshold unexpectedly.
Once total consideration exceeds the threshold, the applicable rate applies to the whole amount, which makes accurate calculation essential.

Property Types and Gray Areas
The mansion tax applies to four New Jersey property classes:
Residential property
Standard homes and residential dwellings.
Farm with a residence
Farm property that contains a residential building.
Commercial property
Commercial property other than industrial or apartment.
Cooperative units
Co-op units held under cooperative ownership.
Mixed use property, farms with a residence, and certain multi unit buildings create gray areas because treatment depends on the legal classification.
In these cases the mansion tax depends on legal classification rather than how the property is used or marketed. This creates complexity in real estate transactions involving non standard property structures, and owners of commercial property especially benefit from small business accounting and planning support to confirm classification before a sale.

Interaction with Transfer Fees
The mansion tax, now officially structured as the Graduated Percent Fee, is applied in addition to the standard Realty Transfer Fee in New Jersey, and both are generally the seller’s responsibility. The Realty Transfer Fee is a separate charge calculated on a sliding scale and has long applied to sellers in New Jersey real estate transfers.
At higher price levels, the combined effect of the Realty Transfer Fee and the Graduated Percent Fee can add tens of thousands of dollars to a seller’s closing costs. Understanding both components is essential when evaluating real estate deals.

Common Misconceptions
One of the most common misconceptions is that New Jersey’s mansion tax, now structured as the Graduated Percent Fee, applies only to ultra-luxury homes. In reality, many standard property transactions in New Jersey are affected once the total consideration exceeds the $1 million threshold.
Another misconception is that only the amount above $1 million is taxed. In fact, once the fee is triggered, the applicable percentage is applied to the full consideration, not just the excess over the threshold.
Clients also frequently underestimate exposure by focusing only on the contract price and ignoring other components of consideration. They may also incorrectly assume the buyer still pays, even though responsibility for the fee generally shifted to the seller for deeds submitted for recording on or after July 10, 2025.

Legislative Changes and Market Impact
New Jersey overhauled these transfer fees in 2025. Governor Phil Murphy signed P.L. 2025, c. 69, A5804/S4666, on June 30, 2025. For deeds submitted to the county for recording on or after July 10, 2025, the law replaced the prior flat 1% “mansion tax” structure with a seller-paid Graduated Percent Fee ranging from 1% to 3.5%, depending on the total consideration, and shifted statutory responsibility from the buyer to the seller.
A limited transition/refund rule applies where the property was transferred under a contract fully executed before July 10, 2025 and the deed was recorded on or before November 15, 2025. In that situation, the seller/grantor may claim a refund of the amount paid above the prior 1% rate by filing a refund claim with the New Jersey Division of Taxation within one year after the deed was recorded. The fee is collected by the county recording officer when the deed is submitted for recording, rather than paid directly to the Division of Taxation at closing.

Exemptions and When the Fee Does Not Apply
The mansion tax does not apply to every sale. It is not triggered in these situations:
$1,000,000 or less
Total consideration at or below the threshold is not subject to the fee.
Other property class
Classes outside the four listed, such as vacant land, qualified farmland, or industrial.
501(c)(3) nonprofit buyer
No fee is owed regardless of the property class when the buyer qualifies.
Other exemptions are claimed on Form RTF-1EE, the affidavit filed with the deed.
Section 10 of 10
Planning Considerations
Because the tax is triggered once consideration exceeds the threshold, it generally cannot be avoided on a qualifying sale through simple structuring. Effective tax planning now focuses on the seller side: budgeting for the fee, confirming property classification, and calculating full consideration.
It also means deciding how the cost is reflected in price negotiations, since the parties can still agree to shift the economic burden by contract.
