Ask what the Peconic Bay transfer tax costs on a Southampton purchase, and most people will quote the headline number: 2.5 percent. Ask what happens the moment a contract price crosses $2,000,000, and the answer changes in a way that catches even repeat East End buyers off guard.
The tax does not rise smoothly as prices climb. It has a cliff built into it, one that erases a real exemption the instant a sale price ticks past two million dollars. In a market where that number sits closer to a starting point than a ceiling for many properties, the cliff shapes more closings here than the sticker rate ever will.
What The Tax Actually Is
The Peconic Bay Community Preservation Fund tax is a transfer tax collected on real estate conveyances across the five East End towns, Southampton among them. The Town of Southampton describes its current version as a 2.5 percent transfer tax, a figure that combines the original Community Preservation Fund levy with a 0.5 percent Community Housing Fund component added on top of it. The original CPF piece has been funding open space and farmland preservation since the late 1990s, and by one account has generated more than $2 billion for that purpose since its inception. The newer CHF layer directs its share toward workforce and first-time buyer housing programs instead.
Both pieces are collected together at closing and filed with the deed at the Suffolk County Clerk's Office, which means a buyer sees the full 2.5 percent as a single line item rather than two separate charges.
The Exemption That Disappears At $2,000,000
Here is the part that gets glossed over in most closing conversations. On an improved residential parcel, the first $400,000 of the sale price is exempt from the tax entirely, but only if the total consideration is $2,000,000 or less. Cross that line by even a dollar, and the exemption does not shrink. It vanishes.
That structure means two buyers paying nearly the same price can owe meaningfully different amounts in transfer tax, and the difference has nothing to do with the size of the exemption itself. It has to do with which side of $2,000,000 they landed on.
| Sale Price | Taxable Amount | Transfer Tax at 2.5% |
|---|---|---|
| $1,950,000 | $1,550,000 (after $400,000 exemption) | $38,750 |
| $2,050,000 | $2,050,000 (no exemption applies) | $51,250 |
A $100,000 difference in price should translate to a $2,500 difference in tax if the rate applied evenly. Instead, it produces a $12,500 difference, because crossing the threshold does not just tax the extra $100,000. It taxes the $400,000 that would have been exempt below the line.
For sellers pricing a home near that number, this is worth understanding before a listing goes live. A price set at $2,050,000 does not just ask a buyer to find an extra $100,000. It asks them to absorb an extra $12,500 in transfer tax on top of that, a detail that surfaces during attorney review, not during a walkthrough.
Who Actually Writes The Check
New York Tax Law § 1449-dd says the tax is paid by the grantee, meaning the buyer, the person acquiring the property or an interest in it.
A closing attorney or title company will collect and remit the tax.
What The Program Is Actually Funding
The scale of this program is larger than most buyers expect. In the first quarter of 2026, the combined Community Preservation Fund and Community Housing Fund brought in more than $45 million across the five East End towns, according to figures reported by State Assemblyman Tommy John Schiavoni's office in June 2026. The CPF portion accounted for $36 million of that and the CHF added roughly $9 million more.
Southampton Town's own cumulative CHF collections have reached $50.8 million since the fund launched in 2023, out of roughly $88.1 million collected region-wide over that same span. That figure reflects the same math outlined above playing out across hundreds of individual closings, each one adding its share depending on where the sale price landed relative to that $2,000,000 line.
The Separate First-Time Homebuyer Exemption
There is a separate exemption that works differently from the improved-parcel allowance, and it matters for a specific buyer profile. Under New York Tax Law § 1449-ee, a qualifying first-time homebuyer can apply for a full exemption from the tax, not a partial one. Under New York Tax Law § 1449-aa, a first-time homebuyer is someone who has not owned a primary residence and is not married to someone who has, going back three years, and who does not own a vacation or investment property at the time of the sale. This exemption does not apply to vacant land, only to improved residential parcels.
The process runs through Southampton's own Community Preservation Fund office in Hampton Bays. For a refund after closing, Southampton's current exemption brochure says the buyer submits the exemption application, a signed prior-year tax return, the executed contract of sale, and the recorded CPF form confirming payment. If the paperwork was not in place in time, the exemption can be requested as a refund afterward. Refund paperwork must be collected in person once it is processed. It is not mailed.
A Few Questions Worth Asking Before Contract
Does the exemption phase out gradually as a sale price approaches $2,000,000, or does it just stop? It stops. There is no partial exemption between $1,999,999 and $2,000,000. The full $400,000 allowance applies at or below $2,000,000, and none of it applies above that amount.
Does the same exemption structure apply to vacant land? Vacant, unimproved residential parcels carry their own exemption, the first $100,000 of the sale price, under the same $2,000,000 consideration cap described above. The first-time homebuyer exemption does not extend to vacant land at all.
Transfer tax mechanics rarely make it into a first conversation about a Southampton purchase, but they shape the real number a buyer needs at the closing table and the real proceeds a seller walks away with. Understanding where the exemption ends, and pricing or negotiating around it deliberately, is the kind of detail that separates a smooth closing from a surprising one.
