There's a version of the real estate conversation that most homeowners experience:
You discuss sale price with your agent, get a sense of how much the commission will be, maybe rough out what you'll walk away with. The closing happens. And then the settlement statement reveals a tax line — sometimes several — that nobody had clearly explained.
New Jersey has a layered tax structure for property sellers. Understanding it in advance doesn't change the obligation, but it changes how clearly you can plan.
The Realty Transfer Fee: The One Most Sellers Encounter First
The Realty Transfer Fee is a state-level tax on the transfer of real property. It applies to essentially every real estate sale in New Jersey and is, in most cases, paid by the seller.
The RTF is calculated in graduated tiers based on the sale price:
- For the first $150,000 of consideration: a specific rate per $500
- For amounts from $150,000 to $200,000: a slightly higher rate per $500
- For amounts above $200,000: the rate continues upward in brackets
The NJ Division of Taxation provides an RTF calculator that applies the current tiered structure to any sale price. On a $300,000 sale, the RTF is typically in the range of $2,700–3,300. On a $450,000 sale, it climbs proportionally.
The fee also has an additional surtax that applies when the property is not a new construction, when the buyer is a non-individual (such as an LLC or corporation), and in other specific circumstances that the seller's attorney will identify.
The RTF shows up on the closing statement as a seller's expense. It's not something that can be negotiated away — it's a state tax.
Capital Gains Exposure: Federal and NJ State
If you've owned a property for more than a year and it has appreciated in value, the profit from the sale is subject to capital gains taxation.
Federal capital gains: Long-term capital gains rates (for assets held more than 12 months) currently range from 0% to 20% depending on your income level. For many sellers, the applicable rate is 15%.
NJ state tax: New Jersey does not have a separate capital gains rate — capital gains from a property sale are taxed as ordinary income at the seller's applicable NJ income tax rate, which ranges from 1.4% to 10.75% depending on income.
The primary residence exclusion: If you've owned and lived in the property as your primary residence for at least 2 of the last 5 years, you may exclude up to $250,000 of capital gain from federal tax (or up to $500,000 for married filing jointly). This exclusion can significantly reduce or eliminate federal capital gains exposure for many sellers.
Investment and rental properties don't qualify for the primary residence exclusion. Sellers of rental properties, second homes, and inherited properties need to calculate capital gains exposure without this offset.
A capital gains calculator that accounts for both federal and NJ state rates gives the clearest picture of actual tax exposure for a specific situation.
The NJ Exit Tax: Specific to Non-Residents
The NJ Exit Tax is one of the more surprising items on a closing statement for sellers who don't live in New Jersey.
Non-resident sellers — those who own property in NJ but whose primary residence is in another state — are subject to a withholding requirement at closing. Specifically, New Jersey withholds 2% of the gross sale price as a prepayment of NJ taxes owed on the transaction.
The 2% is a withholding, not a tax in itself. After the sale, a non-resident seller files an NJ nonresident return and the withheld amount is either applied to the actual tax liability or refunded if the withholding exceeds what's actually owed.
But the cash flow impact is real: 2% of the gross sale price — not the profit, the entire sale price — is withheld at closing. On a $350,000 sale, that's $7,000 held until the return is filed.
For non-resident sellers, this needs to be factored into closing planning so it doesn't create an unexpected shortfall. The Exit Tax affects a meaningful number of sellers who own property in South Jersey (often inherited properties or shore investments) while residing elsewhere.
The Mansion Tax: For Sales Over $1 Million
New Jersey's Mansion Tax is a 1% surtax applied to the sale of residential real estate that sells for $1 million or more.
This tax is technically paid by the buyer, not the seller — but as with any buyer-side cost, it affects what buyers are willing to pay and how deals are structured at price points near the threshold.
For sellers at price points approaching $1 million, the Mansion Tax creates a clear dynamic: buyers are aware that the first dollar above $1 million triggers an additional 1% on the entire price. This sometimes produces negotiation pressure at the threshold, with buyers preferring to structure transactions at $999,999 or pushing for price concessions that effectively offset their Mansion Tax exposure.
Understanding this dynamic before a seller establishes a list price near that threshold can inform a more strategic approach.
The Mortgage Recording Tax: A Common Confusion
The Mortgage Recording Tax in New Jersey is a tax on the recording of a new mortgage — and it's paid by the buyer, not the seller.
It's included here because sellers sometimes see this on a settlement statement or hear it mentioned and aren't sure which direction it flows. To be clear: it's the buyer's cost, associated with their new financing. It doesn't add to the seller's tax burden.
The confusion arises because at closing, all these line items appear on the same settlement statement and the distinction between buyer costs and seller costs can blur.
Running Your Net Proceeds with Taxes Included
The full picture of what a NJ seller pays at closing combines:
- Realty Transfer Fee (seller pays, scaled to price)
- Capital gains tax (seller pays, based on profit and ownership status)
- Exit Tax withholding if applicable (non-residents, 2% of gross price)
- Agent commissions, title insurance, concessions, attorney fees
A rough example: a non-resident NJ homeowner who inherited a $300,000 property five years ago, has a capital gain of $100,000, and sells conventionally:
- RTF: ~$3,000
- Exit Tax withholding: $6,000 (refundable pending return, but withheld at close)
- Capital gains tax (federal 15% + NJ ordinary income rate on gain): estimated $20,000–25,000 total
- Agent commissions, title, fees: $15,000–20,000
Net proceeds could land between $195,000 and $210,000 on a $300,000 sale — roughly 65–70% of the sale price, depending on the specifics.
That calculation should be made explicitly before a decision is finalized.
