The Core Test: Primary Residence Status
New York City's pied-à-terre tax targets one specific category of property: high-value homes that don't serve as anyone's primary residence.
The surcharge, which took effect July 1, 2026, applies a flat annual rate to the full market value of covered properties—but only if they fail the primary residence test. A $2 million Manhattan condo used as its owner's main home owes nothing. The same unit kept as a weekend retreat faces an $80,000 annual bill.
Roughly 24,000 residential units across the city fall above the value thresholds that trigger potential liability, according to Conquest's analysis of DOF's July 2026 Supplemental Market Value Roll. Most are primary residences and owe nothing.
The distinction turns on a legal definition that weighs multiple factors beyond simple day-counting, creating complexity for owners who split time between properties.
Which Properties Face Potential Liability
The tax applies only to three categories of 'covered property' in New York City, according to state Tax Law Article 30-C and NYC Administrative Code Section 11-3202.
Condominiums and cooperative apartments with DOF market values of $1 million or more face surcharge rates of 4% on the full value from $1 million to $3 million, 5.25% from $3 million to $5 million, and 6.5% above $5 million. One- to three-family houses with market values of $5 million or more face lower rates: 0.8% from $5 million to $15 million, 1.05% from $15 million to $25 million, and 1.3% above $25 million.
Manhattan dominates the exposure, with roughly 17,000 condos and co-ops above the $1 million threshold and 3,400 houses above $5 million. Brooklyn follows with about 3,300 houses and 650 condos or co-ops in scope.
The Primary Residence Definition
DOF determines primary residence status as of January 5 preceding each fiscal year, not based on how much of the year an owner spent in the unit.
The statute references occupancy for a majority of days as one factor, but DOF's final rules published July 14, 2026, establish that the agency can weigh additional evidence. Tax practitioners note the majority-of-days test is not the sole or dispositive standard.
DOF's rule Section 62-06 creates a presumption that properties qualify as primary residences if available records show the property listed as the owner's permanent home address on state or federal income tax returns, receipt of STAR exemptions or homeowner tax rebate credits, or evidence that qualifying family members or tenants use it as their primary residence.
The agency can override this presumption only with credible information to the contrary.
Family Member Carve-Outs
Properties escape the surcharge if they serve as the primary residence of the owner's immediate family members, even if the owner lives elsewhere.
The law defines immediate family as spouse, child, sibling, parent, grandparent, or grandchild of the owner. For entity-owned properties, the same relationships apply to individuals who collectively hold a majority interest in the owning LLC, corporation, or partnership.
Consider a Miami-based investor who owns a $1.5 million Upper West Side co-op. If the investor's adult daughter uses the apartment as her primary New York residence, the property avoids the $60,000 annual surcharge despite the owner's non-resident status.
The family exemption requires actual primary residence use, not just occasional visits or emergency access.
Qualifying Tenant Protections
Properties with bona fide tenants who use the unit as their primary residence also escape the tax, regardless of the owner's residency status.
The tenant must hold a lease of at least one year and actually occupy the property as their primary residence. Subletting arrangements qualify if the subtenant meets the same standards.
This provision protects investment properties with legitimate residential tenants from the surcharge. A $2 million Brooklyn brownstone owned by a London-based investor faces no liability if rented to a family under a standard lease who treat it as their primary home.
Short-term rentals, vacation arrangements, and corporate housing typically don't qualify for the tenant exemption.
DOF's Annual Determination Process
DOF must make initial primary residence determinations by August 30 each year, reviewing available records to identify properties that appear to be non-primary residences.
The agency mails notices to owners of properties it believes may be subject to the surcharge. For 2026, DOF extended the exemption application deadline to September 18, 2026, superseding earlier August deadlines.
Owners have 30 days from a notice's transmission date to appeal DOF's initial determination. The agency will review documentation including tax returns, utility bills, voter registration records, and other evidence of primary residence use.
Properties that successfully demonstrate primary residence status avoid the surcharge entirely. Those that don't face their first payment on January 1, 2027.
Geographic Concentration and Market Impact
Manhattan's most expensive neighborhoods show the heaviest concentration of potentially affected units. ZIP code 10019, covering parts of Midtown West, contains 975 condos and co-ops above the $1 million threshold, with an average potential surcharge of roughly $87,000.
SoHo's 10012 ZIP code follows with 932 units, while Tribeca's 10013 contains 1,751 units above the threshold. The West Village, Gramercy, and Upper East Side also show significant exposure.
About 4,400 condo and co-op units citywide have market values within $100,000 of the $1 million threshold, according to Conquest's analysis. These properties face potential liability if values rise in future assessments.
The tax sunsets on June 30, 2031, but Phase 2 changes beginning July 1, 2028, will revalue condos and co-ops using comparable sales methodology and apply the lower house-rate schedule.
What Owners Should Monitor
Property owners should track their DOF market values, which appear on annual Notice of Property Value statements and determine surcharge liability. The tax applies to the full market value, not the assessed value used for regular property taxes.
Owners who received DOF notices have until September 18, 2026, to apply for primary residence exemptions. Documentation should establish the property's use as a primary residence by the owner, qualifying family members, or tenants as of January 5, 2026.
The Comptroller's office projected roughly $500 million in annual revenue from the tax, though actual collections will depend on how many properties qualify for exemptions and how owners respond to the new liability.
