6 core challengesUniformity Clause Violation
The NY Constitution's uniformity clause (Art. XVI § 1) requires all real property to be taxed in a uniform manner. The surcharge creates a dual-class system: condos/co-ops taxed at 4–6.5% of assessed value while one-to-three-family homes are taxed at 0.8–1.3% of market value — a disparity of up to 8x for similar-valued properties. Real estate boards have signaled they will challenge this as property tax discrimination.
Dormant Commerce Clause
The tax targets non-residents specifically, potentially burdening interstate commerce. By imposing a surcharge on out-of-state and international property owners that NYC residents do not pay, the law may violate the Dormant Commerce Clause's prohibition on states discriminating against interstate commerce.
Equal Protection Violation
The surcharge creates a classification between primary residents and non-primary residents. While rational basis review likely applies, plaintiffs may argue the classification lacks a rational relationship to legitimate government interests, especially given that NYC income taxpayers who maintain secondary residences in the city are still subject to the surcharge.
Retroactive Application & Abbreviated Deadlines
The taxable status date of January 5, 2026, preceded the law's enactment on May 28, 2026, meaning owners are being taxed retroactively for a period before the law existed. The 30-day appeal window — later extended to September 18 — has been called insufficient given the complexity of documentation required and the use of potentially outdated government records for residency determinations.
Arbitrary & Capricious DOF Determinations
DOF's Finance Commissioner acknowledged the agency may have used outdated records to identify properties. The initial list ballooned from an estimated 11,000–13,000 properties to over 31,000, with primary residents receiving erroneous notices. Article 78 petitions are expected challenging individual determinations as arbitrary, capricious, and unsupported by evidence.
Innocent Purchaser & Co-op Liability
The surcharge attaches to the property, not the owner, meaning buyers can inherit six years of prior unpaid surcharges. DOF explicitly rejected calls for an innocent purchaser provision. Co-op buildings bear liability for individual shareholders' surcharges with no statutory mechanism to compel reimbursement, exposing buildings to lien sales.
