What is the New Jersey Mansion Tax?

The New Jersey Mansion Tax is a 1% tax applied to residential property sales over $1 million. The buyer is responsible for paying this tax at closing. It applies to both homes and cooperative units, and is calculated based on the total purchase price, not just the amount over $1 million.

The mansion tax also applies to certain commercial properties. The mansion tax was introduced in 2004, when home values were considerably lower than they are now and $1 million home prices were much less commonplace. Unless otherwise agreed upon by the buyer and seller, the mansion tax is typically paid by the buyer at closing.

This tax is applicable to both Class 2 and Class 4A commercial properties, encompassing various types of real estate, such as residential properties (including single-family homes), office buildings, and conventional commercial properties.

The mansion tax is imposed on property deeds involving the following types of properties:

  • Residential property: This category comprises residences for less than four families, including condominiums.
  • Regular farm property: This category covers property used for agricultural or horticultural purposes, provided that the property includes a building or structure intended or suitable for residential use, such as a residential farmhouse.
  • Cooperative units: This category includes properties owned and held by corporations or other legal entities where each shareholder or co-owner has a long-term exclusive lease or similar arrangement for a specific unit within the same building.
  • Commercial property: This category includes any income-producing property, excluding vacant land, residential dwellings, farm properties, industrial properties, or multi-family apartment buildings.

At The Matus Law Group, our attorneys can assist you with your concerns about the mansion tax in New Jersey.

Property Type Applicability of Mansion Tax
Residential Property Applies to residences for less than four families, including condos.
Regular Farm Property Applies to agricultural/horticultural property with a residential use.
Cooperative Units Applies to properties owned by corporations with long-term leases.
Commercial Property Applies to income-producing properties (excludes vacant land).

How is the NJ Mansion Tax Calculated?

In New Jersey, the Mansion Tax is a state-imposed tax that buyers must pay when purchasing residential real estate priced over $1,000,000. The tax rate for this particular duty is set at 1% of the total sales price of the property. This means if you buy a home or any residential property in New Jersey for more than one million dollars, you are required to pay an additional 1% of the purchase price as the Mansion Tax.

The application of the Mansion Tax is broad, covering all deeds where the land conveyed falls under specific classifications according to the New Jersey Administrative Codes (N.J.A.C. 18:12-2.2). Essentially, this tax is applicable to a wide range of high-value residential transactions within the state, underscoring New Jersey’s approach to taxation on higher-end real estate.

For example, if a property is purchased for $1,500,000, the Mansion Tax would be calculated as 1% of $1,500,000, which amounts to $15,000. This tax is paid by the purchaser at the time of closing and is a critical consideration for anyone looking to buy high-end residential property in New Jersey. An experienced real estate attorney can help potential buyers understand this tax obligation, guiding them to budget appropriately and avoid surprises during the property acquisition process.

What Type of Properties Are Subject to the Mansion Tax in New Jersey?

Residential properties in New Jersey that are sold for $1 million or more are subject to the mansion tax. This tax applies to one- to three-family homes, condominiums, and cooperative housing units. The buyer typically pays the tax, which is calculated at 1% of the purchase price.

Can the NJ Mansion Tax Be Deducted on Your Taxes?

The New Jersey mansion tax, a one-time fee paid at closing when purchasing real estate valued at $1 million or more, is not deductible on federal or state income tax returns. It does not qualify as a property tax or mortgage interest expense, which are typically the main real estate deductions available to homeowners.

However, while you cannot deduct this tax directly, it can still impact your tax situation in a different way. The amount paid in mansion tax can be added to your home’s cost basis. A property’s basis includes the purchase price and any qualifying capital improvements or costs related to the purchase, such as the mansion tax. This adjusted basis is important when you eventually sell the home.

When calculating capital gains from the sale of the property, the IRS allows you to subtract the basis from the selling price. So, a higher basis, due in part to the mansion tax, may lower your taxable gain. This can potentially reduce your capital gains tax, particularly if the gain exceeds the primary residence exclusion limits.

The mansion tax doesn’t give you a deduction upfront, but it may help minimize taxes in the future when selling the home. If you’re unsure how this applies to your situation, consulting a New Jersey real estate attorney or a qualified tax professional can provide guidance tailored to your circumstances.

What Properties Aren’t Subject to the Mansion Tax?

Some properties are exempt from the mansion tax in NJ. These include

  • Vacant land
  • Farm property with no existing residence
  • Farm property that qualifies for farmland assessments
  • Industrial properties
  • Apartment buildings with five or more units
  • Cemeteries
  • Schools
  • Churches
  • Properties owned by charitable organizations

Certain types of transfers can also be exempted from the mansion tax. These can include bankruptcies, transfers between family members, transfers in accordance with the terms of a will, transfers in accordance with a divorce decree, correction deeds, or properties sold for a consideration less than $100 if no mortgage exists.

Buyers Should Be Prepared

While $1 million properties are still of significant value, they are definitely more common than they were almost two decades ago in our current real estate market. Considering the real estate site zillow.com has reported that the median home price in New Jersey was $431,899, increasing in value by 16.4 percent in 2021 alone, $1 million dollar homes are more prevalent in the current landscape, and some buyers may be surprised to learn that they are subject to the mansion tax at closing.

As a buyer, it is important to understand whether the purchase of your new property will be subject to the mansion tax and what you can do about it. While the buyer typically pays the mansion tax, they may mitigate the cost by making provisions in the contract agreeing to share them or shift the responsibility to the seller. This may be harder to do in a seller’s market.

The Importance of Having a Real Estate Lawyer

While it is not required to have a real estate attorney when dealing with real estate transactions in New Jersey, having a skilled lawyer can help protect real estate buyers and sellers from the potential legal pitfalls of the large financial decisions involved in such transactions.

Real estate attorneys can assist with closing procedures, property inspections, contracts, disclosures, ownership, and title issues. A lawyer is an invaluable partner who can help ensure fair transactions and legal compliance. Having one can also help limit future problems. A real estate attorney helps both parties understand their rights. A person’s need to hire a real estate lawyer can depend on their knowledge of real estate and contract laws in New Jersey. It is also important to consider hiring a lawyer, especially if the client doesn’t have much experience in buying or selling properties.

Hiring a real estate attorney in the early stages of the transaction can help you spot issues that might go unnoticed until the closing. While real estate agents are skilled in selling property, evaluating offers, and guiding buyers to their ideal home or investment, a real estate attorney can provide invaluable legal advice about potential issues in the transaction.
