New York City has extended the deadline for property owners to apply for exemptions from the non-primary residence surcharge to 6 October 2026, as ongoing litigation and newly available tax data prompt the Department of Finance to provide additional time for affected owners to establish eligibility.
New York’s Department of Finance (DoF) has pushed back the application deadline for exemptions from New York City’s non-primary residence surcharge commonly referred to as the “pied-à-terre tax” to 6 October 2026. This represents the second extension in as many months, following an initial postponement from late August to 18 September 2026.
Who the tax targets
The surcharge applies to properties not occupied as an owner’s primary residence: single-family homes valued at USD 5 million or above, condominiums at USD 1 million or more, and cooperative apartments also at USD 1 million or higher. The Department of Finance initially set separate deadlines for different property classes—21 August 2026 for homes and condominiums, 24 August 2026 for co-ops—before consolidating them under the September extension.
Exemptions and requirements
Owners can claim an exemption if the property serves as a primary residence for the owner, a tenant, or a qualifying family member. Applicants must submit supporting documentation, such as tax returns and identification, by the new October 6 deadline. The Department of Finance processes these claims and notifies owners of decisions. Property owners who contest their property’s valuation or surcharge classification can file a formal challenge through the department’s established procedures.
Litigation pending
Ongoing legal challenges in New York courts over the tax’s administration and implementation appear to have contributed to the Department of Finance extending the deadline twice. The latest extension reflects newly available state tax data and litigation concerning administrative procedures, preliminary eligibility determinations, taxpayer burdens, and due process. The revised deadline is intended to give affected property owners more time to demonstrate eligibility for the exemption.
How the surcharge is applied & calculated
The surcharge is an annual fee levied on specific high-value New York City properties that are not utilised as a primary residence by the owner, a tenant, or an immediate family member. Under state law, cooperative and condominium properties are valued differently than single-family homes. A USD 1 million Department of Finance (DOF) market value for a co-op or condo is legally treated as comparable to a USD 5 million market value for a single-family home.
The progressive surcharge rates for the 2026–27 and 2027–28 tax years are structured as follows:
| Property Type | DOF Market Value | Annual Surcharge Rate (% of market value) |
|---|---|---|
| One-, two-, and three-family homes | USD 5,000,000 to <USD 15,000,000 | 0.8 |
| One-, two-, and three-family homes | USD 15,000,000 to <USD 25,000,000 | 1.05 |
| One-, two-, and three-family homes | USD 25,000,000 or greater | 1.3 |
| Condominium and cooperative units | USD 1,000,000 to <USD 3,000,000 | 4 |
| Condominium and cooperative units | USD 3,000,000 to <USD 5,000,000 | 5.25 |
| Condominium and cooperative units | USD 5,000,000 or greater | 6.5 |
