Which family members can qualify me for the pied-à-terre tax exemption?
The exemption covers properties where your spouse, child, sibling, parent, grandparent, or grandchild lives as their primary residence. That list is exhaustive under the Department of Finance rules — no other family relationships qualify, regardless of how close the connection.
Conquest's analysis of DOF's July 2026 Supplemental Market Value Roll shows roughly 24,000 units citywide would owe the surcharge if they lack qualifying occupancy. In Manhattan alone, 16,700 condos and co-ops fall above the $1 million threshold where family occupancy could determine whether owners face annual bills averaging $68,559.
The exemption requires the family member to occupy the unit as their primary residence, not merely visit or stay occasionally. DOF accepts proof of occupancy during the 12 months preceding the January 5 taxable status date.
What documentation does DOF accept to prove family relationships?
DOF will generally accept birth certificates, marriage certificates, or signed affidavits from both the owner and the occupying family member to establish the relationship. The final rules allow DOF to request additional proof if they have credible information suggesting the claimed relationship is false.
For primary residence status, DOF may accept state or federal tax returns showing the apartment address as the permanent home, or evidence of other primary-residence benefits and credits tied to that address.
Does the exemption work if I own through an LLC or corporation?
Entity ownership can defeat the family exemption even when a qualifying relative lives in the apartment. If you hold title through an LLC, corporation, or partnership, the exemption only applies if one or more individuals collectively hold majority interest — more than 50% of voting power or capital — and the unit serves as their primary residence.
The rules allow interests to be aggregated to reach majority control. But family occupancy alone cannot override entity ownership structures unless the majority-interest requirement is satisfied by qualifying natural persons.
How long must my family member live there to qualify?
The family member must occupy the apartment as their primary residence, with professional summaries indicating occupancy for more than half the year satisfies the standard. The key date is January 5 — the taxable status date preceding each fiscal year — when DOF determines primary residence status.
This creates planning challenges for families with multiple residences. A parent who splits time between a Manhattan co-op and a Florida home must establish the New York apartment as their primary residence as of the January determination date to protect their adult child from the surcharge.
Can I appeal if DOF denies my family exemption?
Property owners have 30 days from a DOF notice's transmission date to appeal non-primary residence determinations. The exemption application deadline was extended to September 18, 2026, for all owners who received DOF notices about potential surcharge liability.
Appeals must address both the family relationship and the primary residence requirement. DOF's burden increases if owners provide the accepted documentation — birth certificates, tax returns, or properly executed affidavits — establishing both elements.
What happens if my family member moves out during the tax year?
Non-primary status is determined as of the January 5 taxable status date, not by how much of the year the family member actually spent in the unit. A grandchild who establishes primary residence by January 5 but moves out in March would still protect the property from that year's surcharge.
This creates both opportunities and risks for tax planning. Families can time residence changes around the annual determination date, but they cannot cure mid-year departures until the following January 5 reset.
Frequently asked questions
Which family members can help me avoid the pied-à-terre tax?
The exemption covers properties where your spouse, child, sibling, parent, grandparent, or grandchild lives as their primary residence. That list is exhaustive under the Department of Finance rules — no other family relationships qualify, regardless of how close the connection.
Does the family exemption still work if I own my apartment through an LLC?
Entity ownership can defeat the family exemption even when a qualifying relative lives in the apartment. If you hold title through an LLC, corporation, or partnership, the exemption only applies if one or more individuals collectively hold majority interest — more than 50% of voting power or capital — and the unit serves as their primary residence.
What happens if my family member moves out in the middle of the tax year?
Non-primary status is determined as of the January 5 taxable status date, not by how much of the year the family member actually spent in the unit. A grandchild who establishes primary residence by January 5 but moves out in March would still protect the property from that year's surcharge.
