Mansion tax calculator
Estimate NYC buyer mansion tax.
Enter estimated taxable consideration for a NYC residential purchase. This tool applies the New York State 1% additional tax at $1 million or more and the New York State supplemental tax for NYC residential conveyances at $2 million or more.
| Line item | Rate used | Estimated amount |
|---|---|---|
| NYS additional tax | 1.00% | $25,000 |
| NYS supplemental tax for NYC residential conveyances | 0.25% | $6,250 |
| Estimated total | 1.25% | $31,250 |
This is a planning estimate, not tax, legal, lender, title, or closing advice. The input should be taxable consideration, not automatically the listing price or contract price. Ask the attorney or title/closing team to confirm taxable consideration, any gross-up issue, and the final transfer-tax forms before relying on a number.
Direct answer: what mansion tax means for a NYC buyer
For a New York City buyer, mansion tax is a buyer-side closing-cost issue that can appear suddenly when taxable consideration reaches $1 million. New York State describes the additional tax as applying to conveyances of residential real property when the consideration is $1 million or more.
This matters before the offer, not only at closing. A buyer comparing $999,000, $999,999, $1 million, $1.5 million, or $2 million should ask the attorney, lender, and title or closing team to model the tax early. Do that before treating a rebate estimate, seller credit, sponsor concession, or cash-to-close number as reliable.
How NYC Buyer Rebate fits into mansion-tax planning
NYC Buyer Rebate is not a tax adviser, law firm, lender, title company, settlement company, or government program. It is a buyer-side broker service model for buyers who may be doing much of the search themselves but still want buyer-side support around offer planning, written representation terms, transaction coordination, and conditional rebate review.
That role matters near a mansion-tax threshold because the buyer should not look at rebate math, seller credits, sponsor concessions, or cash-to-close numbers in isolation. The buyer-side broker can help keep the right questions organized, while the attorney, lender, title or closing team, and tax professional handle the professional determinations.
If we are working together and a property is near $1 million, $2 million, or another rate threshold, flag the issue before offer terms are set. The useful next step is not guessing from a listing price; it is asking the right professionals how taxable consideration, contract-shifted costs, lender documents, and any approved credits should be reviewed.
Do not confuse contract price with taxable consideration
The common shortcut is to ask, 'Is the purchase price at least $1 million?' That shortcut is often useful, but it is not the whole analysis. Transfer-tax rules are based on consideration, and tax professionals often describe consideration as including the price paid or required to be paid plus certain mortgages, liens, encumbrances, assumed debt, or buyer-paid seller obligations, depending on the transaction.
That is why a buyer can see a sub-$1 million contract price and still have a mansion-tax question. In a sponsor or new-development deal, for example, the contract may require the buyer to pay sponsor attorney fees, NYC/local transfer taxes, or other seller-side costs. Some buyer-paid seller obligations can affect grossed-up consideration calculations, while certain residential transfer-tax amounts may be excluded under current New York State guidance. The buyer should not decide this from the listing price alone.
Practical example: a $999,000 contract does not automatically mean 'no mansion tax.' If taxable consideration is increased by includable contract-shifted costs or other includable amounts and reaches $1 million or more, the tax question changes. Ask the attorney or title team to show the calculation on the transfer-tax forms before assuming the threshold is avoided.
The $1 million threshold is a cliff, not a marginal bracket
The basic mansion-tax threshold is not a slow phase-in. If the residential purchase consideration is below $1 million, the 1% additional tax generally is not triggered by that threshold. At $1 million, a 1% tax would be $10,000 before any transaction-specific issues. At $1.5 million, the same 1% framework would be $15,000.
The tax applies to the taxable consideration, not just to the dollars above the threshold. That is the part many buyers miss. If the threshold is crossed, the buyer is not paying 1% only on the first dollar over $1 million.
That does not mean a buyer should structure an offer only around a tax cliff. Price, comps, building strength, financing, seller leverage, contract terms, sponsor demands, and attorney advice still matter. The useful move is to know when the cash-to-close estimate changes materially.

How to read the table
Buyers often describe the combined burden as a 1% to 3.9% NYC mansion-tax schedule. More precisely, the first 1% is the New York State additional tax that applies to residential conveyances at $1 million or more. The second column is also a New York State tax, but it is a supplemental tax that applies to NYC residential conveyances starting at $2 million.
That is why the $1 million to under $2 million range shows 1% in the NYS additional-tax column and none in the supplemental-tax column. At $2 million or more, the buyer adds the supplemental percentage to the 1% additional tax. These rates should be applied only after the correct taxable consideration is calculated. A buyer should ask the attorney or title team whether the relevant number is simple contract price, grossed-up consideration, allocated residential consideration, excluded residential transfer-tax amounts, or another transaction-specific figure.
Example: $2.5 million resale with no gross-up
Assume a NYC residential resale has taxable consideration of $2,500,000 and, for simplicity, there is no gross-up or contract-shifted item changing the calculation. The buyer is in the $2 million to under $3 million row.
NYS additional tax: 1.00% of $2,500,000 = $25,000. NYS supplemental tax for NYC residential conveyances: 0.25% of $2,500,000 = $6,250. Total buyer mansion-tax amount under this simplified example: $31,250.
That example does not include NYC RPTT, mortgage recording tax, title charges, lender charges, attorney fees, building fees, sponsor-shifted costs, rebates, credits, or tax treatment. In a resale, NYC RPTT is a separate transfer tax concept and is not the same as the buyer mansion-tax calculation shown here.
Who usually pays
New York State's public transfer-tax guidance says the base and additional base taxes are paid by the seller unless a contract provides otherwise, while the additional tax and supplemental tax are paid by the buyer. In ordinary buyer planning language, mansion tax should be treated as a buyer cash-to-close item unless the buyer's attorney says the contract changes the allocation.
A sponsor deal can be more complicated because the contract may shift costs, define sponsor fees, include concessions, or allocate transfer taxes differently from a simple resale expectation. If the buyer is contractually paying costs that are normally seller costs, the taxable-consideration calculation may need a gross-up analysis, but the treatment can differ by cost type and residential-property rule. Buyers should not rely on a generic closing-cost chart when a sponsor rider or offering-plan structure is involved.
Mansion tax is separate from NYC RPTT and mortgage recording tax
NYC Real Property Transfer Tax is a separate city transfer tax concept. NYC Finance states that RPTT applies when a sale or transfer is more than $25,000 and is usually paid as part of closing costs. For many residential transfers, NYC publishes different rates depending on the transfer type and price.
Mortgage recording tax is also a separate issue for financed purchases where it applies. A buyer should not combine all of these into one informal 'tax' number. Ask the attorney, lender, and title or closing team to separate each line so the buyer knows which items are seller-side, buyer-side, contract-shifted, lender-controlled, or property-type-specific.
How it affects rebate and closing-credit planning
A buyer-side rebate or broker credit should not be treated as an automatic offset against mansion tax. A rebate estimate can depend on written buyer-side terms, eligible buyer-side compensation actually received, brokerage approval, lender review, closing treatment, and transaction facts.
If a buyer hopes a rebate or credit will reduce cash due at closing, route that question early. The buyer should ask the lender how the credit would appear on the Loan Estimate or Closing Disclosure, ask the attorney how it should be documented, and ask the closing team whether the final statement reflects only approved treatment. The NY buyer commission rebate guide explains why estimates should remain conditional until those checks are complete.
Ready to discuss a specific NYC purchase?
If you are looking at a NYC condo, co-op, townhouse, or sponsor unit near a mansion-tax threshold, you can start with the buyer intake form. Keep the first message practical: listing link, property type, asking price or accepted price if known, financing status, resale or sponsor status, whether you already contacted the listing side, and what mansion-tax, closing-cost, or rebate question you want to clarify.
Do not upload sensitive documents through a first-contact message. Bank statements, tax returns, IDs, Social Security numbers, wire instructions, board-package materials, and full lender files should stay with the appropriate secure professional process.
Buyer scenarios and checkpoints
A buyer considering a $995,000 resale should understand how close the price is to the $1 million threshold before bidding up. A buyer considering a $1 million condo should ask whether the 1% additional tax is included in the cash-to-close estimate. A buyer considering a $2 million NYC unit should ask about both the 1% additional tax and the NYS supplemental tax schedule for NYC residential conveyances.
A buyer considering a $999,000 or $999,999 sponsor unit should ask whether buyer-paid transfer taxes, sponsor attorney fees, or other contract-shifted costs change taxable consideration. A sponsor-unit buyer should add contract-review questions: whether sponsor transfer taxes, sponsor attorney fees, mansion tax, working-capital contributions, and concessions are clearly separated. A co-op buyer should ask counsel whether the same transfer-tax forms and calculations apply to the specific cooperative transaction.
What changes the answer
The answer changes with purchase price, taxable consideration, property type, borough, whether the transaction is resale or sponsor sale, financing, contract allocation, assumed debt, liens or encumbrances, transfer-tax forms, title or settlement workflow, and any approved credit or concession.
It can also change if official tax guidance, forms, or rate instructions change. This is why buyers should use current official sources and transaction professionals instead of relying only on an old online calculator or a prior friend's closing statement.
What this article does not decide
This article does not decide the tax due on a particular transaction, who must pay under a particular contract, whether a rebate or credit can offset cash to close, or how any line item should be reported after closing.
It is general NYC buyer process education, not legal, tax, accounting, mortgage, title, settlement, financial-planning, or investment advice.
