New York's non-primary residence surcharge: what non-resident owners should expect

What was enacted

In May 2026 New York State added Article 30-C to the Tax Law. It allows the City to add a surcharge to the property tax on high-value homes that are no one's primary residence. The surcharge applies from the fiscal year that began on 1 July 2026. It expires on 30 June 2031 unless renewed. The Department of Finance (DOF) adopted its rules on 10 July 2026 (19 RCNY Chapter 62).

Which properties, and at what rates

The surcharge covers one- to three-family houses, condominium units and cooperative units. What matters is the market value on DOF's Notice of Property Value, not the purchase price. The rate applies to the whole value, not only to the part above the threshold.

Condominium and cooperative units have a lower threshold and higher rates. This is because DOF still values them on a rental basis, which usually gives a figure well below the sale price. From 1 July 2028 all covered property moves to a sales-based value and a single $5 million threshold. Units without a required certificate of occupancy and unsold sponsor units are excluded. For cooperatives, the corporation is billed and passes the charge on to the shareholder.

What counts as a primary residence

The test is applied on 5 January before each fiscal year. The home must be the primary residence of an individual owner or of an immediate family member: a spouse, child, sibling, parent, grandparent or grandchild. A home is also exempt if an individual tenant lives there as a primary residence under a genuine arm's-length lease of at least one year.

Homes held through a company or a trust

This is where non-resident owners need the most care. The statute looks through one entity only. The individuals who together hold a majority interest are treated as the owners. For a trust, only a sole beneficiary counts. DOF's rules do not allow primary residence to be established through a multi-tier structure, such as a New York company owned by a foreign company. If no individual qualifies, only the tenant route remains.

It is not yet settled whether DOF will accept occupancy by a family member of the majority holder. A formal lease may be the safer route.

Notices, deadline and challenges

DOF based its initial determinations on tax and exemption records. Owners who disagree must respond through DOF's online portal, with supporting documents, by 6 October 2026. Otherwise the surcharge will appear on the property tax bill due 1 January 2027. An owner who misses the deadline, or disagrees with DOF's final decision, may apply to the New York City Tax Commission. A final denial can be challenged in court under Article 78. DOF may audit any submission for six years.

What owners should do now

• Check the market value on the Notice of Property Value. It decides whether the home is above the threshold.
• If a notice arrived, respond through the portal before 6 October 2026. Do so even if the case for primary residence seems obvious.
• If the home is held through a company or a trust, test the structure against the majority-interest and sole-beneficiary rules.
• If a relative or friend lives there without a lease, consider a written lease of at least one year at a realistic rent. It should be in place before 5 January 2027.
• Keep every document for at least six years.
