Suffolk County transfer tax calculator
Type a sale price and see what the state takes, who pays it, and whether the mansion tax lands. Rates come from the New York State Department of Taxation and Finance, not from a rule of thumb.
East End buyers: pick your town and the Peconic Bay preservation tax lands in the buyer column. Priced below.
What each tax is
State transfer tax, paid by the seller. New York charges $2 for every $500 of the price, or fractional part of it, which is 0.4 percent. On a $700,000 sale that is $2,800. It is the one nearly every Suffolk seller pays, and it comes off the proceeds at closing.
Mansion tax, paid by the buyer. One percent of the whole price once a residence reaches $1,000,000. Read that again, because it catches people: it is a cliff, not a bracket. At $999,000 the tax is nothing. At $1,000,000 it is $10,000. There is real money in that one dollar, and it is worth negotiating around when a price lands near the line.
What Suffolk County does not charge. There is no county transfer tax on top of the state one. You will also see calculators that add New York City's extra taxes, the additional base tax and the supplemental tax that runs up to 2.9 percent. Those apply to property inside the five boroughs only. Applied to a Suffolk sale they overstate the bill by thousands.
The East End is different, and this page now prices it. Buyers in East Hampton, Riverhead, Shelter Island, Southampton and Southold pay into the Peconic Bay Community Preservation Fund, and most of those towns added a community housing fund on top. The combined rate is 2.5 percent in East Hampton, Southampton, Shelter Island and Southold, and 2 percent in Riverhead. Each town lets you subtract an allowance from the price before the tax is figured: $400,000 on improved property in East Hampton, Southampton and Shelter Island, $200,000 in Southold, $150,000 in Riverhead, with smaller allowances on vacant land. In every town except Riverhead the allowance disappears entirely once the price passes $2,000,000. First time buyers can qualify for a full exemption, which the calculator does not assume, so ask about it if that is you. Pick your town in the calculator above and the figure lands in the buyer column. These figures come from the Judicial Title rate schedule, confirmed in writing through a lender partner in August 2026.
Buying in Nassau instead. The state taxes are identical, but Nassau adds its own stack of recording fees at the County Clerk. The Nassau version of this page covers those.
What this does not include
Transfer taxes are one line on a closing statement. A seller also carries the attorney, the payoff, and the brokerage fee. A buyer carries the lender fees, the title insurance, the survey, and the recording costs. If you want the whole picture for your own sale rather than one line of it, the free home review lays every number out side by side.

Common questions
How much is the transfer tax in Suffolk County, NY?
The state charges $2 for every $500 of the sale price, which is 0.4 percent, and the seller pays it. On a $700,000 sale that is $2,800. Suffolk County adds no transfer tax of its own. The five East End towns charge a separate preservation fund tax that the buyer pays.
Who pays it, the buyer or the seller?
The seller pays the state transfer tax. The buyer pays the mansion tax when one applies, and the buyer pays the Peconic Bay preservation tax on the East End. If the seller does not pay, the buyer becomes liable, which is one reason it gets settled at the closing table rather than afterward.
What is the mansion tax on Long Island?
One percent of the whole purchase price on a home selling for $1,000,000 or more, paid by the buyer. At $999,000 it is nothing and at $1,000,000 it is $10,000, so a price sitting near the line is worth a conversation before the contract is signed.
Do the New York City surcharges apply here?
No. The additional base tax and the supplemental tax apply to property in New York City only. Several calculators apply them statewide, which overstates a Suffolk seller's cost by thousands of dollars.
Where do these rates come from?
The New York State Department of Taxation and Finance, on its real estate transfer tax page, checked when this page was built. Rates change by law, so if you are closing on a specific date, confirm with your attorney or title company. Nothing here is legal or tax advice.
Disclaimer: every figure on this page is computed with the calculation formulas published by the New York State Department of Taxation and Finance: the real estate transfer tax at $2 for each $500 of consideration or fractional part, and the mansion tax at 1 percent of consideration at $1,000,000 and above, plus the Peconic Bay preservation fund rates and allowances from the Judicial Title rate schedule, confirmed in writing through a lender partner in August 2026. Actual charges at your closing may vary with the specifics of the transaction, exemptions, and any change in law. Your attorney and title company provide the binding figures. This page is a starting point, not legal or tax advice, and not a closing statement.
