If you close on a Sutton Place apartment this winter and plan to use it as a second home, January 5, 2027 is the date that decides your 2027-28 bill under New York City's new non-primary-residence surcharge. What matters on that date is how the apartment is used. Your plans for it don't count. When the Department of Finance wrote its final rule, commenters asked for an exception for buyers who intend to move in but haven't yet. DOF declined. It said state law bases primary residency on a property's use as of the taxable status date. The Tax Commission defines that date as January 5 of the calendar year before the fiscal year the surcharge applies to.
The second surprise is the number the surcharge is measured against. For co-ops and condos in tax years 2026-27 and 2027-28, it isn't your purchase price. It is DOF's market value, and in Sutton Place that number can sit several million dollars below what a buyer actually paid.
The Date and the Lease That Decide Who Pays
DOF's surcharge page says the charge generally does not apply if the property is the primary residence of the owner, a tenant or subtenant, an immediate family member of the owner, majority holders of an owning entity, or the sole beneficiaries of a trust. For tenants, the Tax Commission requires a real, arm's-length lease with a term of at least a year. Immediate family covers a spouse, child, sibling, parent, grandparent or grandchild.
The leasing route is already showing up in the rental market. The Real Deal reported in August 2026 that high-end landlords were asking tenants to certify full-time New York residency, in some cases requesting W-2s or tax returns, and adding full-time-residency riders to leases.
What the City Says a $9.2 Million Sutton Place Condo Is Worth
In late October 2026, The Real Deal reported a $9.2 million sale of a 4,631-square-foot condominium at 252 East 57th Street in Sutton Place, recorded in ACRIS. DOF's tax year 2026-27 Notice of Property Value for that unit, 60A, dated January 16, 2026, lists a market value of $2,258,415. That is about a quarter of the sale price.
The gap comes from how the city values these properties. For Class Two property, full value is set by capitalizing the income of comparable rental buildings. A co-op unit's value is its share of the whole building's value, in proportion to the shares tied to that apartment. DOF says plainly that a co-op or condo it values at $1 million or more is generally comparable under state law to a single-family home valued at $5 million or more. That is why the threshold for apartments is so much lower.
For 2026-27 and 2027-28, the co-op and condo rates are:
- 4.0% on a DOF value of at least $1 million but less than $3 million
- 5.25% on at least $3 million but less than $5 million
- 6.50% on $5 million or more
Each rate applies to the entire value, not just the portion above the line. The NYC Comptroller's analysis shows the cliff: a unit valued at $0.99 million owes nothing, and one at $1.00 million owes $40,000. At 4%, a unit carrying Unit 60A's DOF value would face roughly $90,300 a year in any year it wasn't anyone's qualifying primary residence. That figure only shows how the math works. It says nothing about any owner's status.
Sutton Place's Co-ops on the Same Scale
Now apply the same yardstick to the neighborhood's best-known co-ops. These figures come from the FY2027 final assessment roll in NYC Open Data, divided across each building's co-op apartments.
| Building | DOF market value, FY2027 roll | Co-op apartments | Average per apartment |
|---|---|---|---|
| 1 Sutton Place South | $71,230,000 | 43 | about $1,656,500 |
| 35–45 Sutton Place | $71,378,000 | 127 | about $562,000 |
| 2 Sutton Place South | $62,015,000 | 127 | about $488,300 |
| 25–35 Sutton Place South | $145,347,000 | 320 | about $454,200 |
| 1 Beekman Place | $57,400,000 | 136 | about $422,100 |
Four of the five averages fall well under the $1 million line. The fifth, 1 Sutton Place South, sits above it, and it is still below the DOF value of the single condo at 252 East 57th Street. These are building averages. A large apartment with a heavy share allocation can be valued far above its building's average, so a unit's own exposure depends on its shares.
The citywide numbers point the same way. Working from the FY2026 assessment roll, the Comptroller's notional estimate counted 7,721 condominiums and 1,184 co-op units among about 13,586 properties that could be subject to the surcharge. That was before any exemptions or appeals. For the first two years, the surcharge falls mostly on condos.
Inside a Co-op, the Building Pays the City First
Co-op owners are less likely to be valued over the line, but co-ops carry a different burden. The surcharge goes on the corporation's statement of account, and the corporation collects it from the tenant-stockholder. In the August 2026 issue of Habitat Magazine, Dan Wollman, president of Gumley Haft Management, described the budgeting problem:
"So when the city adds a couple of taxes on top of that we won't really have enough money set aside. Then you've got people who don't want to pay it, leaving the co-op in a very awkward position."
In the same piece, Dennis DePaola, chief legal officer at Orsid New York, said, "We've got no idea how we're going to collect these amounts." DOF has said it will not write rules that override proprietary leases. Instead it suggested that co-op corporations consider amending their leases so the charge is allocated to the right shareholder. The Real Deal reported that industry sources warned the legal and lien exposure could lead some co-ops to stop allowing second homes altogether.
For a second-home buyer, this changes what a Sutton Place co-op purchase involves. The unit's share-based DOF value may keep it under the threshold. Even so, a board now has a financial reason to look at how the apartment will be used, and the proprietary lease may soon spell out who pays.
Where the Rollout Stands This Week
- May 28, 2026. The governor signed the state budget bill, Chapter 59. Part HH authorizes the surcharge.
- July 23–24, 2026. DOF began mailing "may be subject" letters and published a supplemental market value roll.
- October 13, 2026. The exemption deadline closed after three extensions. Habitat reported more than 6,800 exemptions granted from upwards of 11,000 applications. Another 1,251 of the roughly 17,000 owners who got letters were told they were not responsible.
- September 29 and October 28, 2026. A trial judge ordered the city to redo the rollout. That order is on hold while the city appeals, and the Second Department heard arguments on October 28. The city's lawyer said bills would go out within about two and a half weeks, according to The Real Deal. Habitat reported a decision expected by November 10. Two constitutional challenges are also pending in Suffolk County.
- January 1, 2027. Any surcharge owed appears on the property tax bill due that day.
After 2028, the Yardstick Changes
The gap between DOF value and sale price only lasts two years. From FY2029, DOF will estimate co-op and condo values from comparable sales, for this surcharge only. Units will be subject at a sales-based $5 million or more, with rates of 0.8%, 1.05% and 1.3%. The surcharge runs from FY2027 through FY2031. Once that switch happens, the co-ops that stay under the line today on share-based values will be measured the way a buyer measures them.
Questions Owners Raise
Can I still challenge the value? Yes. According to the Tax Commission's surcharge appeal page, for both 2026-27 and 2027-28 an appeal of DOF's market value must be filed by March 1, 2027 for Class Two property, which includes co-ops and condos, and by March 15, 2027 for Class One. That deadline does not move. Residency is handled differently. If you first appealed DOF's residency determination to DOF, you can appeal its final determination to the Tax Commission by the same March date or within 30 days of the final notice, whichever is later. Only one surcharge appeal may be filed with the Tax Commission for any one year. The Comptroller's summary of the law notes that in phase one, owners can contest DOF's figure, but not on the grounds that the apartment would sell for less than $5 million.
Why did I get a letter if this is my only home? DOF says letters went to owners whose records didn't let it confirm primary residence. One example it gives is a co-op or condo receiving the abatement without a sufficient tax filing on record.

Before you sign a contract or a board package on a Sutton Place apartment you may not live in full time, look up its DOF value, its share allocation and the building's current approach to the surcharge.
