Two contracts. Same town, same property type, submitted the same week. One is priced at $1,999,999. The other, a dollar higher, at $2,000,000. On paper, that's a rounding error. On the closing statement, it's a $10,000 difference in what the buyer owes East Hampton before the deed even records.
That gap has nothing to do with negotiation, financing, or inspection contingencies. It comes from a single, specific mechanism buried in the Peconic Bay Community Preservation Fund transfer tax, the 2.5 percent levy every East Hampton buyer pays at closing. Most closing-cost breakdowns treat this tax as a flat percentage. It isn't. Above $2,000,000, the exemption that shelters the first chunk of a home's price disappears entirely, and the whole purchase price becomes taxable. That's the cliff, and it's worth understanding before you're the one standing at the edge of it with a contract in hand.
The Math on Either Side of the Line
Here's how the same 2.5 percent rate produces two very different bills depending on which side of $2,000,000 a deal lands.
- Below $2,000,000: the first $400,000 of an improved property's price is exempt. On a $1,999,999 contract, the taxable amount is $1,599,999. At 2.5 percent, that's roughly $40,000.
- At or above $2,000,000: the exemption vanishes completely. The entire purchase price becomes taxable. On a $2,000,000 contract, that's $50,000.
A one-dollar difference in contract price. A $10,000 difference in what the buyer writes a check for at the closing table. This isn't a marginal tax bracket where only the dollars above the threshold get taxed at a higher rate. It's a full reset. Cross the line and the exemption you'd have gotten on the first $400,000 is gone, retroactively, on the whole deal.
Vacant land works the same way at a lower entry point. The exemption for unimproved parcels is $100,000 below $2,000,000, and it disappears just as completely once the price reaches that same $2,000,000 mark.
Where the Cliff Came From
This wasn't always how the tax worked. The CPF itself dates to 1998, when East End voters approved a 2 percent real estate transfer tax to fund farmland, open space, and historic preservation. It was introduced by state Assemblyman Fred Thiele of Sag Harbor, built loosely on a similar program that had worked on Nantucket since the 1980s.
"It's clear that conservation could not have kept pace with development here without the CPF."
Voters extended the tax's authority through 2050 in a 2016 referendum. But the cliff itself is newer. In November 2022, voters in East Hampton, Southampton, and Shelter Island approved an additional 0.5 percent tax to fund community housing, bringing the combined rate to 2.5 percent. That same legislative package raised the base exemption from $250,000 to $400,000, a win for buyers on more modest purchases, but it also eliminated the exemption entirely for any conveyance at or above $2,000,000. The changes took effect for conveyances on or after April 1, 2023, and they remain the law today.
In other words, the cliff is a deliberate policy choice, not an oversight. It's a way of extending a bigger break to buyers at the lower end of the market while asking larger transactions to carry the full weight of the tax with no cushion. The tradeoff is that it creates a sharp, calculable discontinuity right at $2,000,000, exactly where a meaningful share of East Hampton contracts land.
Not the Same Thing as the Peconic Land Trust
One point of confusion worth clearing up here: the CPF is frequently mixed up with the Peconic Land Trust, a private nonprofit that has worked on farmland and open space protection on the East End since 1983. They're not connected. The Land Trust doesn't receive a cent of the transfer tax. The CPF is a town government program, and in East Hampton it has real scale: the fund recorded $44,149,355 in transfer tax receipts in 2024 alone, money that goes toward acquiring and preserving open land, wetlands, farmland, and historic structures within town and village borders, with up to 20 percent allowed for water quality projects.
That distinction matters for the same reason the cliff matters. Buyers hear "preservation fund" and assume it's a modest, feel-good add-on. In practice it's a substantial line item collected by the town itself, governed by a specific ordinance, and structured in a way that can move by five figures based on a single dollar.
Why This Matters More in East Hampton Right Now
The cliff isn't a hypothetical for a small slice of ultra-luxury buyers. Listing data from mid-August 2026 put East Hampton's median asking price at $2.19 million, meaning a large share of homes currently on the market sit at or above the exact point where this exemption disappears. For a market where the typical listing is already brushing up against $2,000,000, the difference between a deal that closes just under the line and one that closes just over it isn't an edge case. It's the default situation for a lot of East Hampton buyers this year.
It's also worth remembering this tax stacks with New York's statewide mansion tax, which adds 1 percent on any purchase price of $1,000,000 or more, applied to the full price rather than the amount above the threshold. Combine the two, and a $2,000,000 East Hampton purchase carries $50,000 in CPF tax and another $20,000 in mansion tax before attorney fees, title insurance, or anything else touches the closing statement.
What This Means When You're Structuring an Offer
None of this is a workaround, and it isn't tax advice. But it is the kind of detail that changes how a serious offer gets structured, and it's the same incentive that shows up around New York's mansion tax cliff at $1,000,000, where buyers and sellers sometimes negotiate seller credits or adjust pricing during attorney review specifically to land on the more favorable side of that line. The dollar amounts at stake around the $2,000,000 CPF threshold are considerably larger, which makes early attention to exact contract price even more worthwhile.
A few practical implications worth raising with your attorney before you sign anything:
- If your offer is close to $2,000,000, know exactly which side of the line the final negotiated price lands on. A late concession or a small bump to cover a repair credit can push a deal across the threshold without anyone intending it to.
- The cliff applies to the contract price, not the appraised value or any other number. Structuring around it is a conversation for your real estate attorney, not a DIY exercise.
- If you're purchasing vacant land with plans to build, remember the exemption threshold is lower ($100,000) but the same $2,000,000 cliff applies.

Quick Answers
Who actually pays the CPF tax, buyer or seller? The buyer. It's collected at closing as part of the buyer's costs, separate from the seller's transfer tax obligations.
Does the $2,000,000 cliff apply everywhere in the Hamptons? The cliff itself, no exemption at or above $2,000,000, applies across East Hampton, Southampton, Shelter Island, Southold, and Riverhead. But the underlying rate and exemption amount differ by town. East Hampton, Southampton, and Shelter Island share the 2.5 percent rate and $400,000 exemption described here. Southold also charges 2.5 percent but with a lower exemption. Riverhead has kept its original 2 percent rate.
Is there any way around the cliff? Not through pricing games. The tax is based on the actual contract price, and misrepresenting that price carries real legal risk. The only real strategy is knowing the threshold exists early enough to factor it into how you negotiate, not after the closing statement arrives.
If you're weighing an East Hampton purchase anywhere near that $2,000,000 mark, or trying to figure out what a specific price point actually costs once every line item is on the table, that's exactly the kind of detail worth talking through before you make an offer.
