Which family members qualify for the immediate family pied-à-terre exemption?
The NYC pied-à-terre tax exempts properties used as primary residences by an owner's spouse, child, sibling, parent, grandparent, or grandchild. That statutory list under Tax Law Article 30-C is exhaustive.
The exemption does not extend to domestic partners, fiancés, in-laws, cousins, aunts, uncles, nieces, nephews, or other household members. A Manhattan co-op owner whose domestic partner lives in the unit as their primary residence would not qualify for the family exemption, even in a long-term relationship.
For entity-owned properties, the family exemption applies when the property serves as a primary residence for an immediate family member of one or more individuals holding a majority interest in the entity.
What documents does DOF require to prove family exemption eligibility?
DOF requires documentation showing both the occupant's relationship to the owner and their use of the property as a primary residence. The proof must be assembled per occupant, not just identifying the owner's family generally.
The available DOF materials establish the evidentiary framework but do not publish a closed document checklist specifying that particular items like birth certificates, marriage certificates, or tax returns are categorically sufficient in every case.
DOF's final rules and application instructions control the documents actually required for submission. Owners should consult the current DOF guidance rather than assume any single document type will satisfy both relationship and primary-residence requirements.
How does the family exemption work for entity-owned properties?
The immediate family exemption extends to properties owned by LLCs, trusts, or other entities when the property serves as a primary residence for an individual with majority interest in the entity or their immediate family member.
A Brooklyn brownstone owned by an LLC would qualify if the majority owner's adult child uses it as their primary residence. The exemption would not apply if only a minority owner's family member occupied the property.
DOF has not resolved how it will measure majority ownership in complex structures, how indirect or tiered interests are treated, or what entity records will be required beyond proof of the occupant's relationship and residence.
What happens if multiple family members use the property?
The exemption applies when any qualifying immediate family member uses the property as their primary residence. Multiple family members can share the residence without affecting eligibility.
An Upper East Side condo used jointly by an owner's elderly parents as their primary residence would qualify for the exemption. The same would apply if the owner's adult sibling and grandparent both lived there as their primary home.
When is the exemption application deadline?
The current exemption application deadline is October 13, 2026, after multiple extensions from the original August 2026 dates. DOF mailed notices to owners whose records did not establish primary-residence status on July 22, 2026.
The deadline applies to all property owners who received a DOF notice stating "You may be subject to..." the surcharge. A court challenge produced an automatic stay that kept the exemption process in effect while appeals remained pending.
Which properties are exposed to the surcharge without exemptions?
Conquest's analysis of DOF's July 2026 Supplemental Market Value Roll shows roughly 24,000 units citywide would owe the surcharge if they are non-primary residences. Most are likely primary residences and owe nothing.
Manhattan accounts for roughly 17,000 condos and co-ops above the $1 million threshold, with an average potential surcharge of $68,559. Brooklyn has about 3,300 houses above the $5 million threshold for single-family properties, averaging $52,630 in potential surcharge.
The surcharge rates are 4% of market value for condos and co-ops valued $1-3 million, 5.25% for $3-5 million, and 6.5% above $5 million. Houses face lower rates: 0.8% for $5-15 million, 1.05% for $15-25 million, and 1.3% above $25 million.
What should owners watch for next?
The first surcharge payments are due January 1, 2027, for properties that do not qualify for exemptions. DOF will issue final determinations on exemption applications before then.
Owners have 30 days from a notice's transmission date to appeal DOF decisions. The surcharge runs through June 30, 2031, when the law sunsets unless renewed.
Starting July 1, 2028, the rate structure shifts toward the lower house rates for all property types, based on comparable sales valuations rather than current DOF market values.
