The mansion tax in New Jersey is a supplemental realty transfer fee applied to certain property transfers exceeding $1 million. Under the 2025 amendments and current state guidance, the seller is generally legally responsible for paying this fee on deeds submitted for recording on or after July 10, 2025, replacing the original 2004 framework that placed the burden on the buyer. The fee applies to residential property, cooperative units, certain farm property that includes residential use, and Class 4A commercial property under N.J.S.A. 46:15-7.2.

Whether you are purchasing your first home or selling a high-value property, having a residential real estate lawyer review your contract can help you avoid costly surprises at closing.
This guide explains what the mansion tax is, who pays it under the new law, how it is calculated, which properties are exempt, and how the 2025 changes affect buyers and sellers. Call The Matus Law Group at (732) 785-4453 to speak with Christine Matus about your real estate transaction.
What Is the New Jersey Mansion Tax?
The New Jersey mansion tax is a supplemental fee added to the standard Realty Transfer Fee (RTF) on property sales over $1 million. The state legislature first enacted it in 2004 under N.J.S.A. 46:15-7.2 as a flat 1% tax on the total purchase price. At the time, $1 million homes were relatively uncommon. The threshold has never been adjusted for inflation, which means more properties trigger the tax today than when the law was first introduced.
The tax is separate from the standard RTF that sellers have paid since 1968 under N.J.S.A. 46:15-5. Both fees are collected by the county recording officer when the deed is submitted for recording. In Monmouth County, for instance, deeds are recorded at the County Clerk’s Office at 33 Mechanic Street in Freehold.
The mansion tax applies to the full purchase price, not just the amount above $1 million. For example, a home sold for $1.2 million would trigger a 1% tax on the entire $1.2 million, resulting in a $12,000 fee. This distinction catches many buyers and sellers off guard, because they assume the tax only covers the portion exceeding the threshold.
Who Pays the NJ Mansion Tax Under the 2025 Law?
Under the original 2004 law, the buyer was responsible for paying the 1% mansion tax at closing. On June 30, 2025, Governor Phil Murphy signed Bill S4666/A5804. Under New Jersey’s current guidance, for deeds submitted for recording on or after July 10, 2025, legal responsibility for the mansion tax shifted from the buyer to the seller, subject to a limited grace-period refund rule for certain contracts fully executed before July 10, 2025 and recorded on or before November 15, 2025.
This change means sellers of qualifying properties must now pay the mansion tax in addition to the standard RTF they already owed. The law also introduced a graduated rate structure for properties sold above $2 million. For sales between $1 million and $2 million, the rate remains 1%.
What Are the New Mansion Tax Rates?
The 2025 law replaced the flat 1% rate with a tiered system for higher-value transactions. The rates apply to the total consideration stated in the deed.
| Sale Price Range | Tax Rate | Who Pays |
|---|---|---|
| $1,000,001 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 |
These are flat rates applied to the entire purchase price. A home sold for $2.1 million, for instance, would incur a 2% tax on the full $2.1 million, totaling $42,000. This tiered structure can create significant cost differences at each threshold.
How Is the NJ Mansion Tax Calculated?
The mansion tax is calculated as a percentage of the total consideration stated in the deed. The New Jersey Division of Taxation collects this fee through the county recording officer at the time the deed is offered for recording.
Calculation Examples
A straightforward way to understand the tax is through examples at different price points.
- A property sold for $1,500,000 falls in the 1% tier. The mansion tax is $15,000.
- A property sold for $2,200,000 falls in the 2% tier. The mansion tax is $44,000, not $22,000 on just the amount over $2 million.
- A property sold for $3,600,000 falls in the 3.5% tier. The mansion tax is $126,000.
Because each tier applies to the full consideration, the jump from one bracket to the next can be steep. Selling a property for $1,999,000 instead of $2,001,000 would mean the difference between a $19,990 tax and a $40,020 tax.
The mansion tax is paid in addition to the standard RTF, which the New Jersey Division of Taxation calculates on a separate sliding scale. Together, these fees represent a significant closing cost for high-value real estate transactions in the state.

What Properties Are Subject to the Mansion Tax?
The mansion tax applies to specific property classifications as defined by the New Jersey Administrative Code (N.J.A.C. 18:12-2.2). Not every real estate transaction over $1 million triggers this fee.
Properties subject to the mansion tax include:
- Residential property (Class 2): One- to four-family homes and condominiums
- Farm property (Class 3A): Agricultural land that includes a residential dwelling, such as a farmhouse
- Cooperative units: Properties held by corporations where shareholders hold exclusive leases for individual units
- Commercial property (Class 4A): Income-producing properties such as office buildings and retail spaces, excluding vacant land, industrial properties, and apartment buildings with five or more units
The classification is determined by the municipal tax assessor. If you are unsure whether your property falls into a qualifying class, a real estate attorney can review the tax assessment records filed with your county tax board.
Key Takeaway: The mansion tax applies to residential homes, condos, cooperative units, certain farm properties, and Class 4A commercial properties sold for over $1 million. Municipal tax assessments determine the classification.

What Properties Are Exempt from the Mansion Tax in New Jersey?
Several property types and transaction types are exempt from the mansion tax under N.J.S.A. 46:15-10.
Exempt Property Types
The following properties are not subject to the supplemental realty transfer fee, regardless of the sale price:
- Vacant land with no structures
- Farm property that qualifies for farmland assessment and has no residential dwelling
- Industrial properties
- Apartment buildings with five or more units
- Cemeteries, schools, churches, and properties owned by tax-exempt organizations under Internal Revenue Code Section 501(c)
Exempt Transaction Types
Certain transfers are also excluded from the mansion tax. These include transfers between spouses or between parents and children, transfers made by an executor or administrator in accordance with a will or New Jersey intestacy law, correction deeds, transfers recorded within 90 days of a divorce decree, sales for delinquent taxes, and transfers by a receiver or trustee in bankruptcy.
A property transferred to an organization that the Internal Revenue Service (IRS) has determined to be exempt from federal income tax is also not subject to the fee. When a deed is exempt from the graduated percent fee, the parties should use the current Affidavit of Consideration for Graduated Percent Fee (Form RTF-1EE) and make sure the exemption is properly stated in the deed package submitted for recording.
Key Takeaway: Vacant land, qualified farmland without a residence, industrial properties, and apartment buildings with five or more units are exempt from the mansion tax. Several transaction types, including transfers between family members and estate distributions, are also excluded.
Christine Matus can review your transaction to determine whether an exemption applies.
How Does the 2025 Law Change Affect Buyers and Sellers?
The 2025 amendment to N.J.S.A. 46:15-7.2 represents the most significant change to the mansion tax since its creation. Both buyers and sellers need to understand how it alters contract negotiations and closing costs.
Impact on Sellers
Sellers of properties over $1 million now bear the full cost of the mansion tax in addition to the standard RTF. For a $1.5 million sale, the seller’s total transfer tax burden can exceed $25,000 when combining both fees. Sellers of properties above $2 million face substantially higher costs under the graduated rate structure.
This change affects pricing strategies. Some sellers may increase their asking price to offset the new tax obligation. Others may need to negotiate with buyers over who ultimately absorbs the cost. While the law places legal liability on the seller, the parties can contractually agree to allocate the fee differently.
Impact on Buyers
Buyers benefit from the removal of the 1% fee they previously owed at closing. However, the cost may still be passed through indirectly if sellers raise prices to compensate. Buyers should review the contract language carefully, because the parties remain free to shift the tax obligation by agreement.
Transition Rules
The law includes a transition period for contracts that were fully executed before July 10, 2025. If the deed was recorded on or before November 15, 2025, the seller can apply to the New Jersey Division of Taxation for a refund of any amount paid in excess of 1%. The refund claim must be filed within one year of the deed recording date.
Why Do You Need a Real Estate Attorney for a Mansion Tax Transaction?
While New Jersey does not require a real estate attorney to complete a property transaction, working with one is particularly important when the mansion tax is involved. The financial stakes are higher, and the 2025 changes have introduced new difficulties.
A real estate attorney can review the purchase or sale contract to confirm who is responsible for the mansion tax. An attorney can also verify whether the property qualifies for an exemption. For properties near a price threshold, such as the $2 million boundary where the rate jumps from 1% to 2%, an attorney can advise on pricing strategies that reduce the overall tax burden.
The county clerk’s office collects the mansion tax alongside the standard RTF when the deed is submitted for recording. Any errors in the consideration statement or the exemption affidavit can delay the recording and potentially hold up the closing. An attorney ensures all forms, including Form RTF-1 and Form RTF-1EE, are completed correctly.
Beyond the Mansion Tax
Real estate attorneys also conduct title searches, review inspection reports, and handle closing procedures. For transactions in Red Bank and surrounding communities where home values frequently approach or exceed $1 million, the mansion tax is often a factor that requires careful planning.
Key Takeaway: A real estate attorney can review contracts, verify exemptions, and ensure all transfer tax forms are correctly filed. This is especially important for high-value transactions where the mansion tax creates a significant closing cost.
