New Jersey Real Estate Transfer Tax Calculator

New Jersey's Realty Transfer Fee applies marginal brackets ranging from 0.58% on the lowest tier of consideration up to 1.21% on amounts above $1 million, under the schedule in N.J.S.A. 46:15-7. Layered separately on top, a Graduated Fee, commonly called the mansion fee, applies once consideration reaches $1 million or more, and unlike the base brackets it is a cliff: the full bracket rate, running from 1% up to 3.5% at the highest tier, applies to the entire consideration, not just the amount above the threshold.

A change effective July 10, 2025 shifted the mansion fee's payer from the buyer to the seller, reversing the rule that had applied for two decades before that date; the base Realty Transfer Fee remains seller-paid as it always has been. Because of that 2025 amendment, closing documents or advice referencing the older buyer-paid mansion tax rule should be treated as outdated for any New Jersey transaction closing under current law.

Using the calculator's baseline $380,000 sale price, which stays below the Mansion Fee threshold:

• Sale Price: $380,000
• $0 to $150,000 at 0.58%: $150,000 × 0.0058 = $870.00
• $150,000 to $200,000 at 0.85%: $50,000 × 0.0085 = $425.00
• $200,000 to $380,000 at 0.96%: $180,000 × 0.0096 = $1,728.00
• Base Fee subtotal: $870 + $425 + $1,728 = $3,023.00
• No Mansion Fee applies (price is under $1,000,000)
• Transfer Tax Due: $3,023.00
• Net Proceeds After Tax: $380,000 minus $3,023 = $376,977.00
• Effective Rate: 0.796%

At the higher-value scenario of $1,500,000, the base fee across all six brackets totals $15,625.00, and because the price meets the $1,000,000 Mansion Fee threshold, the entire $1,500,000 is also taxed at the Mansion Fee's 1.0% bracket rate ($15,000.00). Combined transfer tax due: $15,625 + $15,000 = $30,625.00, an effective rate of roughly 2.04%, showing how sharply total cost rises once a sale crosses the Mansion Fee threshold.

• Senior, blind, disabled, and affordable-housing partial exemptions. New Jersey offers reduced Realty Transfer Fee rates for qualifying senior citizens, blind or disabled sellers, and certain low- and moderate-income housing transactions, none of which this calculator models.
• The exact cliff-edge behavior just above $1,000,000. Because the Mansion Fee applies its full bracket rate to the entire price rather than marginally, a sale at exactly $999,999 and a sale at $1,000,001 can produce a materially different total fee. This calculator computes the correct statutory result at any price entered, but users should be aware of how sharply the cost changes right at the threshold.
• County recording fees. New Jersey county clerks charge separate flat recording fees per document, unrelated to the value-based Realty Transfer Fee and Mansion Fee calculated here.
• New construction and certain commercial transaction nuances. Some New Jersey transaction types carry fee variations not captured by the standard consideration-over-$350,000 schedule this calculator uses.

• Treating the Mansion Fee as marginal. Unlike the base Realty Transfer Fee, the Mansion Fee is a cliff: once the $1,000,000 threshold is met, the bracket rate applies to the full consideration, not just the amount above $1,000,000. Applying it marginally understates the tax significantly.
• Forgetting the Mansion Fee is seller-paid. As of the July 2025 amendments, the Graduated (Mansion) Fee is specifically a seller obligation, distinct from the base Realty Transfer Fee, which historically has different buyer and seller cost-sharing conventions depending on transaction type.
• Assuming the old $1,000,000 flat 1% mansion tax rule still applies. New Jersey's mansion tax structure changed substantially in 2025 to a graduated cliff schedule with rates up to 3.5%, replacing the previous flat 1% rule; using outdated guidance will produce the wrong number on higher-value sales.
• Using a rounded average rate instead of the marginal bracket table for the base fee. Because the base fee has six distinct brackets, estimating with a single blended percentage instead of working through each tier produces an inaccurate result, especially for sales near a bracket boundary.
