New York City will impose a new annual surcharge on certain residential properties that are not used as a primary residence, beginning July 1, 2026. Lawmakers approved the new pied-à-terre tax surcharge as part of New York State’s fiscal year 2027 budget, and it is expected to affect owners of higher-value second homes, including individuals, foreign investors and properties held through LLCs, corporations and trusts.
This surcharge is in addition to existing property taxes and may significantly increase the annual cost of holding New York City real estate.
How the Surcharge Works
The tax applies to residential properties in New York City that are not the owner’s primary residence, subject to specific value thresholds:
- One- to three-family homes (Class 1): Generally subject to the surcharge once the value exceeds $5 million
- Condominiums and co-ops (Class 2): Subject to lower initial thresholds during the initial phase due to current assessment methodologies (generally $1 million NYC Department of Finance (DOF) market value, which may correspond to a significantly higher fair market value)
Although co-ops and condominiums are valued below their true market value for NYC tax purposes, the initial phase also uses a significantly lower threshold (generally $1 million DOF market value). As a result, many properties with much higher underlying market values may still be captured in the initial phase.
Two-Phase Structure
The surcharge is implemented in two phases:
- Phase One begins on July 1, 2026: Uses fair market values for Class 1 properties (1 to 3 family homes), current NYC Department of Finance valuation methodologies for Condominiums and Co-ops
- Phase Two (Beginning July 1, 2028): Transitions to a market-based valuation approach using comparable sales, with a unified rate structure across property types.
Surcharge Rates (Key Detail)
The surcharge is applied on a tiered basis, increasing as property value rises:
Phase One – Condominiums & Co-ops (≥ $1M DOF value)
- 4.0% on value from $1M–$3M
- 5.25% on value from $3M–$5M
- 6.5% on value above $5M
Phase One – One- to Three-Family Homes (≥ $5M)
- 0.8% on value from $5M–$15M
- 1.05% on value from $15M–$25M
- 1.3% on value above $25M
Phase Two – All Covered Properties (≥ $5M market value)
- 0.8% on value from $5M–$15M
- 1.05% on value from $15M–$25M
- 1.3% on value above $25M
Because valuation methods differ across property classes, the resulting tax exposure may not align with perceived market value, making upfront modeling an important step in planning.
Why This Matters
The impact can be significant—particularly during Phase One for condos and co-ops.
Example:
A condominium unit with a $1 million NYC assessed value would generate:
- Approx. $40,000 annual surcharge at the 4.0% rate
For higher-value properties, the increase becomes even more pronounced. For example:
- A unit with a $4 million assessed value could generate an annual surcharge exceeding $200,000, depending on how value falls within the tiers
These examples highlight how quickly the surcharge can escalate and why property valuation methodology is critical in estimating exposure.
Key Exemptions
Certain properties may qualify for an exemption, including:
- The property is used as the owner’s primary residence or the primary residence of an immediate family member
- Properties leased under a bona fide, arm’s-length arrangement where the tenant occupies the unit for at least one year.
Properties that remain vacant or are held for intermittent personal use are generally expected to remain within scope.
Planning Considerations for Owners
This new tax introduces meaningful planning considerations for affected property owners:
- Documentation supporting primary residence status will be critical
- Rental strategies may mitigate exposure if structured properly
- Acquisition, disposition, and valuation planning will require additional diligence
The surcharge takes effect July 1, 2026, with the first notices and compliance requirements expected shortly thereafter.
Given the complexity of valuation rules and the magnitude of potential tax exposure, early modeling and planning are essential, particularly for high-value properties where the surcharge can materially impact annual cash flow.
