On May 27, 2026, state lawmakers passed the city's first-ever pied-à-terre tax — a recurring annual surcharge on residential properties used as second homes by owners who live elsewhere. After more than a decade of failed attempts, it's finally law. If you own a non-primary residence in New York City, or you've been thinking about buying one, this changes your calculus significantly.
This is where things get nuanced, and it's worth slowing down.
In the first phase, covering tax years 2026–2027 and 2027–2028, condos and co-ops valued at over $1 million by the NYC Department of Finance are subject to the tax. The rates on assessed value are 4% for properties valued between $1M and $3M, 5.25% for $3M to $5M, and 6.5% for anything above $5M.
Here's the catch that many people are missing: the city's property assessment system dramatically undervalues real estate. City valuations can often represent 10% or less of actual market value, which means the assessed value subject to the tax is far lower than what you paid or what your apartment would sell for today. That buffers the immediate sting but only in the first phase.
Starting in fiscal year 2028–2029 (phase two), condos and co-ops will be revalued closer to market rates, and the tax structure shifts to a different rate schedule. That's when the real financial impact lands for many owners. According to CNBC's reporting, Citadel CEO Ken Griffin, whose 220 Central Park South penthouse is assessed at $15.5 million despite a $238 million purchase price, would see his property tax bill go from $858,332 today to $1.87 million under phase one, and nearly $4 million under phase two.
For Class 1 houses (one-to-three family homes), the $5 million assessed value threshold applies from the start, using a graduated rate on a separate schedule.
Mayor Zohran Mamdani and Governor Kathy Hochul have been explicit about the two goals: close a significant budget gap and make housing ownership more costly for those using New York City real estate as a wealth storage vehicle rather than as a home. The NYC Mayor's Office announced the proposal in April alongside projections of roughly $500 million in annual revenue from approximately 11,200 qualifying properties.
New York is also not alone in this trend. Vancouver's "empty homes tax," various European vacancy levies, and London's second-home surcharges have all established a global template for this approach.
Residency is self-certified. Each year, the NYC Department of Finance will make an initial determination of which properties appear to be non-primary residences. For fiscal year 2026–2027, the DOF must send notices to affected owners by August 30, 2026, giving them an opportunity to submit proof of primary residence before the surcharge is finalized. This means the clock is already ticking if you're a current owner who might qualify for an exemption.
Owners who misrepresent their primary residence status face penalties of up to 50% of the surcharge after a notice and hearing process. That's a serious consequence, and it signals that enforcement is built into the framework from day one.
A lot of buyers are confused on this point, and it's an important distinction. The mansion tax is a one-time transfer tax paid at closing when you purchase a property above a certain value. The pied-à-terre tax is a recurring annual surcharge. If you're an out-of-state buyer purchasing a $5M+ Manhattan condo, you could owe both: mansion tax once when you close, and the pied-à-terre surcharge every single year you hold the property as a non-primary residence.
Opinions are genuinely split. Real estate brokers and tax attorneys have noted significant sticker shock, and some observers expect motivated sellers in the $5M+ segment in the near term as owners who don't want to hold under this structure decide to exit. That could create buying opportunities in that bracket for primary-residence buyers who are unaffected by the surcharge.
There's also a question of whether some owners will pivot to renting their units out, which would generate NYC income taxes and potentially qualify the property differently.
Longer term, the political durability of the tax is worth watching. Previous NYC tax structures (421-a, J-51, the mansion tax surcharge) have been amended, extended, phased out, and revived. Anyone making long-term decisions around this tax should model it as likely permanent over the next five years, while keeping one eye on the 2027 mayoral election and future legislative sessions.
If you own a non-primary residence in NYC, the most important immediate step is to consult with a licensed attorney and a CPA who understand NYC property tax law. You have until August 30, 2026 to submit proof of primary residency if you believe you qualify for an exemption. Do not wait on this.
If you're a buyer considering a pied-à-terre in NYC, you need to underwrite the annual surcharge into your holding costs from day one; not as an afterthought. The economics of ownership have shifted, and any analysis that doesn't account for this recurring charge is incomplete.
