Property classification under New Jersey property-tax rules. RESIDENTIAL covers Class 2 single-family and 2-4 unit residences, Class 4A 4+ unit residential, and the residential portion of Class 3B farm-with-house. COMMERCIAL / MIXED-USE covers pure commercial, industrial, and Class 4B / 4C properties. The distinction matters: the Mansion Tax (§ 46:15-7.2) and the Supplemental Fee (§ 46:15-7.4) apply ONLY to residential transfers; commercial / mixed-use pays the RTF only.

How this calculator works
New Jersey stacks three distinct transfer-tax layers on a single real-estate transfer. Unlike most state transfer-tax stacks, the three layers split across BOTH sides of the closing table — the seller pays the Realty Transfer Fee (RTF) and the Supplemental Fee; the buyer pays the Mansion Tax. The combined effective rate on a typical North Jersey luxury sale runs north of 2.3% of consideration, materially heavier than New York State outside the five boroughs.
This calculator models all three layers and surfaces the customary seller / buyer allocation so each side knows their exposure before the contract is signed:
- Realty Transfer Fee (RTF) — N.J.S.A. 46:15-5 et seq., seller-paid, tier-based from 0.40% to 1.21%.
- Mansion Tax — N.J.S.A. 46:15-7.2, buyer-paid, 1% of the full consideration, residential transfers of $1M+.
- Supplemental Fee — N.J.S.A. 46:15-7.4, seller-paid, $1.00 per $500 marginal on residential consideration above $350K.
Layer 1 — Realty Transfer Fee (N.J.S.A. 46:15-5 et seq.)
The Realty Transfer Fee under N.J.S.A. 46:15-5 et seq. applies to every transfer of New Jersey real property by deed, statewide, residential and commercial alike. It is seller-paid. The fee schedule is tier-based: the consideration determines a single per-$500 rate, and that rate is applied to the entire consideration — not marginally.
The statutory schedule:
| Consideration range | Rate per $500 | Effective % | |------------------------------|---------------|-------------| | $0 - $150,000 | $2.00 | 0.40% | | $150,001 - $200,000 | $3.35 | 0.67% | | $200,001 - $250,000 | $3.90 | 0.78% | | $250,001 - $350,000 | $4.80 | 0.96% | | $350,001 - $550,000 | $5.30 | 1.06% | | $550,001 - $850,000 | $5.80 | 1.16% | | $850,001 - $1,000,000 | $6.05 | 1.21% | | $1,000,001+ | $6.05 | 1.21% |
The non-marginal mechanic is the critical mental model. A $300,000 sale falls in the $250,001 - $350,000 tier and pays $4.80 per $500 on the full $300,000 = $2,880 — not $4.80 per $500 only on the $50,000 above $250K. A $1,000,001 sale hits the top tier at $6.05 per $500 and pays $12,100 on the full $1,000,001. Crossing a tier boundary materially changes the seller-side bill.
Layer 2 — Mansion Tax (N.J.S.A. 46:15-7.2)
The Mansion Tax under N.J.S.A. 46:15-7.2 is buyer-paid. It is a flat 1% of the full consideration, triggered the moment two conditions are both met: (1) the property is residential (Class 2 single-family / 2-4 family, Class 4A residential 4+ unit, or the residential portion of Class 3B farm-with-house), AND (2) consideration is $1,000,000 or more.
When triggered, the levy applies to the whole sale price — not just the dollars above $1M. A $999,999 residential sale pays $0 in Mansion Tax. A $1,000,001 residential sale pays $10,000.01. This cliff effect at exactly $1M is real and is one of the most common negotiation flashpoints in New Jersey residential closings: buyers and sellers regularly negotiate purchase prices to land at $999,999, or to allocate the $1,001-plus of consideration to personal-property items conveyed separately.
Commercial and mixed-use sales do not pay the Mansion Tax, regardless of price. A $5M Newark office building has zero Mansion-Tax exposure.
Layer 3 — Supplemental Fee (N.J.S.A. 46:15-7.4)
The Supplemental Fee under N.J.S.A. 46:15-7.4 is the only layer that is genuinely marginal. It is seller-paid, $1.00 per $500 of consideration above $350,000 (= 0.20% of the marginal amount), residential only.
On a $400,000 residential sale, the Supplemental Fee runs on the $50,000 above $350K = $100. On a $1,500,000 residential sale, it runs on the $1,150,000 above $350K = $2,300. On a $5,000,000 residential sale, it runs on the $4,650,000 above $350K = $9,300. Layered on the seller's side on top of the RTF, the Supplemental Fee adds approximately 20 basis points of effective rate at the margin.
Worked example — $400,000 residential standard sale
A $400,000 single-family home, North Jersey middle-market. Standard sale, no exemption.
- RTF tier: $5.30 per $500 (tier covering $350,001 - $550,000) → 1.06% × $400,000 = $4,240 (seller).
- Supplemental Fee: $1.00 per $500 × ($400,000 - $350,000) = $1 × 100 = $100 (seller).
- Mansion Tax: $0 (under the $1M residential threshold).
- TOTAL: $4,340 (~1.09% effective).
- Seller customary share: $4,340. Buyer customary share: $0.
At the middle-market price band the buyer side is clean — the seller absorbs the full transfer-tax burden. This is the typical New Jersey starter-home closing.
Worked example — $1,200,000 residential standard sale
A $1,200,000 single-family home, suburban Bergen County. The Mansion Tax has just engaged.
- RTF tier: $6.05 per $500 (top tier, > $1M) → 1.21% × $1,200,000 = $14,520 (seller).
- Supplemental Fee: $1.00 per $500 × ($1,200,000 - $350,000) = $1 × 1,700 = $1,700 (seller).
- Mansion Tax: 1.00% × $1,200,000 = $12,000 (buyer).
- TOTAL: $28,220 (~2.35% effective).
- Seller customary share: $16,220 (RTF $14,520 + Supplemental $1,700).
- Buyer customary share: $12,000 (Mansion Tax).
Just above the $1M Mansion-Tax threshold the buyer-side bill is meaningful — $12,000 on its own, larger than the seller's Supplemental Fee. Negotiations over who absorbs the Mansion Tax are routine in this price band.
Worked example — $1,500,000 residential luxury sale
The canonical NJ luxury closing. A $1,500,000 single-family home.
- RTF: 1.21% × $1,500,000 = $18,150 (seller).
- Supplemental Fee: $1 per $500 × ($1.5M - $350K) = $2,300 (seller).
- Mansion Tax: 1.00% × $1,500,000 = $15,000 (buyer).
- TOTAL: $35,450 (~2.36% effective).
- Seller customary share: $20,450. Buyer customary share: $15,000.
The combined three-layer burden tops $35K on a $1.5M sale. Compare to a Manhattan residential sale at the same price — the NYC stack (NY State 0.4% + NY mansion 1% + NYC RPTT 1.425% + NYC Additional 0% under $2M = roughly $43K) sits modestly above; outside NYC, New Jersey is the heavier transfer-tax jurisdiction in the metro area.
Worked example — senior seller, $500,000 residential sale
A $500,000 sale, seller is 70 years old. The N.J.S.A. § 46:15-10.1 partial exemption applies.
- RTF base: $5.30 per $500 × $500,000 = $5,300 (pre-exemption).
- RTF actual (after 50% partial exemption): $2,650 (seller).
- Supplemental Fee: $1 per $500 × ($500K - $350K) = $300 (seller, not reduced by exemption).
- Mansion Tax: $0 (under $1M).
- TOTAL: $2,950 (~0.59% effective).
The partial exemption cuts the seller's RTF roughly in half but does not touch the Supplemental Fee. The exemption is claimed at recording on Form RTF-1EE with documentation of age, blindness, disability, or low-income housing status.
Worked example — $2,000,000 commercial / mixed-use sale
A $2,000,000 Class 4B office condominium in Newark. Commercial, not residential.
- RTF: 1.21% × $2,000,000 = $24,200 (seller).
- Supplemental Fee: $0 (residential only).
- Mansion Tax: $0 (residential only).
- TOTAL: $24,200 (~1.21% effective).
Commercial / mixed-use sales escape both the Mansion Tax and the Supplemental Fee — only the RTF applies. A $5M residential single-family pays nearly double the transfer-tax burden of an otherwise-identical $5M commercial sale.
Customary allocation between seller and buyer
The customary split in New Jersey residential closings tracks the statutory structure:
- Seller pays the Realty Transfer Fee (§ 46:15-5 et seq.) and the Supplemental Fee (§ 46:15-7.4).
- Buyer pays the Mansion Tax (§ 46:15-7.2), where applicable.
The split is custom and structural — § 46:15-7.2 names the grantee (buyer) as the responsible taxpayer for the Mansion Tax, and the RTF / Supplemental Fee statutes name the grantor (seller) — but the purchase contract can reallocate. In soft markets sellers occasionally absorb the buyer-side Mansion Tax to close the deal. In bidding-war scenarios on trophy properties the reverse shows up. The convention is sticky in New Jersey practice but not statutorily compelled.
The § 46:15-10.1 partial exemption
N.J.S.A. § 46:15-10.1 grants a partial RTF exemption — not a full waiver — when the seller is (a) age 62 or older, (b) legally blind, (c) totally and permanently disabled, or (d) selling property that qualifies as low- and moderate-income housing. The statutory formula on Form RTF-1EE reduces the RTF rate to approximately $0.50 per $500 (= 0.10%) on the first $350,000 plus a moderately-reduced rate above $350,000 — collectively approximating a 50% reduction of the RTF base over the typical residential range. This calculator models the exemption as a flat 50% reduction to keep the math transparent; the precise statutory formula is more granular at the tier boundaries.
The Mansion Tax (§ 46:15-7.2) and the Supplemental Fee (§ 46:15-7.4) are not reduced by this exemption. The exemption is claimed at recording on Form RTF-1EE with supporting documentation. Only one seller need qualify for a joint-tenancy or tenancy-by-the-entirety sale.
Comparison with New York
| Sale type | NJ (this calc) | NY State (non-NYC) | NYC residential | |----------------------------|--------------------|---------------------------|------------------------------| | $500K residential | $4,940 (~0.99%) | $2,000 (0.40%) | ~$9,125 (NYC ~1.825%) | | $1.5M residential | $35,450 (~2.36%) | $21,000 (~1.40%) | ~$50K (~3.34%) | | $5M residential | $119,800 (~2.40%) | $132,500 (~2.65%) | ~$253K (~5.06%) |
Outside the five boroughs, New Jersey is meaningfully heavier than New York State on residential transfers — driven by the RTF tier and the Supplemental Fee, neither of which has a clean NY analog. Inside NYC, the borough RPTT + Additional Tax stack pulls ahead. Cross-river buyers in the NYC metro regularly factor the spread into closing-cost allocation.
Common errors
Three mistakes turn up repeatedly in New Jersey transfer-tax math:
-
Treating the RTF tier as marginal. The selected per-$500 rate applies to the whole consideration, not just the dollars in the bracket. A $300K sale pays $4.80 per $500 × $300K = $2,880 — not $4.80 per $500 only on the $50K above the prior tier ($120).
-
Omitting the Supplemental Fee on $350K+ residential sales. The Supplemental Fee (§ 46:15-7.4) is the layer most commonly missed by out-of-state attorneys and the "online closing-cost calculators" that model only the headline RTF. On a $1.5M residential sale the omission understates the seller's burden by $2,300.
-
Applying the Mansion Tax to commercial / mixed-use property over $1M. The Mansion Tax (§ 46:15-7.2) is residential only — a $5M Class 4B office building pays zero Mansion Tax. A surprisingly common error in mixed-portfolio commercial closings.
What this calculator does not do
This is a planning and screening tool. It does not:
- Substitute for the county clerk's filing. Realty transfer fees are paid at the county recording office at the time the deed records. The county clerk computes and collects on the basis of Form RTF-1 (and RTF-1EE where applicable). Use this calculator to model the closing; the actual filing is a closing-agent function.
- Model § 46:15-10 full exemptions for intra-family gifts, mere-change-in-form transfers, governmental conveyances, or charitable transfers. Those are fact-specific and require attorney review.
- Address refinances — no deed transfer means none of the three layers apply, and New Jersey does not impose a separate mortgage-recording analog.
- Apply to transfers outside New Jersey. The New York, Pennsylvania, Delaware, and federal regimes bear no resemblance to the New Jersey three-layer stack.
How this page is maintained
The New Jersey transfer-fee regime has been structurally stable since the Supplemental Fee was added in 2004 and the Mansion Tax was enacted in 2004 — three layers, same boundaries. Periodic legislative proposals to lift the Mansion Tax threshold or shift it onto sellers have surfaced but none have passed as of this review. We monitor New Jersey Division of Taxation bulletins, NJ Legislature transfer-fee bills, and Form RTF-1 / RTF-1EE revisions each session and refresh the calculator within 30 days of any enacted change.
These are planning tools, not tax or legal advice. Consult a New Jersey-licensed attorney or tax advisor before acting on a result — particularly on non-arm's-length transfers, the § 46:15-10.1 partial exemption, or any transaction landing near the $1M Mansion Tax cliff.

FAQ
Common questions
Edge cases and clarifications around new jersey realty transfer fee + mansion tax calculator.
New Jersey stacks three distinct taxes on a single real-estate transfer. Layer 1 — the Realty Transfer Fee (RTF) under N.J.S.A. 46:15-5 et seq., a seller-paid tier-based fee that ranges from $2.00 per $500 (= 0.40%) on consideration up to $150,000 through $6.05 per $500 (= 1.21%) on consideration above $1,000,000. The selected per-$500 rate applies to the ENTIRE consideration, not marginally. Layer 2 — the Mansion Tax under N.J.S.A. 46:15-7.2, a buyer-paid 1% of the full consideration triggered only on residential transfers of $1,000,000 or more. Layer 3 — the Supplemental Fee under N.J.S.A. 46:15-7.4, a seller-paid $1.00 per $500 (= 0.20%) of consideration ABOVE $350,000 on residential transfers; this is the only layer that is genuinely marginal.
