New York City's attempt to tax owners of high-value second homes has instead swept up thousands of longtime, full-time residents, forcing them into a bureaucratic appeals process that advisors to wealthy clients say is far from settled.
The pied-à-terre surcharge, approved by state lawmakers in Albany this spring and championed by Mayor Zohran Mamdani, was designed to apply to one-to-three-family homes worth at least $5 million and co-ops or condominiums valued at $1 million or more that sit empty or serve as non-primary residences.
City officials have said the tax could generate roughly $500 million a year for New York's budget, money the administration wants to direct toward affordability initiatives such as city-owned grocery stores and free bus service.
Cting a spokesperson for the mayor's office, the Wall Street Journal reported that Instead of a narrow list of second-home owners, the city's Department of Finance sent notices to 17,000 property owners this month.
A separate document dump reported by the New York Post identified roughly 960,000 properties as potentially subject to review – orders of magnitude more than Governor Kathy Hochul's office's earlier estimate that only about 10,000 second homes would ultimately be taxed.
Among those notified was Bob Ohlerking, an 82-year-old who has lived in his Park Slope brownstone for 55 years. He received a letter stating the home was not his primary residence and that he owed a $44,048 surcharge based on a $5.56 million valuation.
"I've paid taxes for 55 years. All of that stuff is on record," Ohlerking told the Post. "It's annoying. It's not gonna upset my life forever. It's just annoying."
Karen Young, president of a Manhattan-based marketing firm who has lived in the city since 1972, said she was billed roughly $43,000 on a West 95th Street brownstone she has occupied with her husband for three decades. "Whoever's behind this, who I can only assume is the mayor, didn't take the 30 seconds to research," Young said. She said she spent three hours trying unsuccessfully to submit proof of residency online before hiring an estate lawyer to complete the paperwork.
Not every case involves a straightforward homeowner. Pasquale Giordano, 76, has served as trustee of a family brownstone since his father died 15 years ago; his sister still lives there. He received a notice citing a $5.7 million valuation and a $45,776 surcharge, and disputes both the valuation, which he says jumped from $4.3 million a year earlier, and the city's characterization of the property as non-primary given his sister's residency.
Homeowners who believe they were incorrectly billed have two options to appeal, depending on the basis for their dispute. Those contesting based on residency status have a 30-day window from the notification date to file a rebuttal directly with the Department of Finance. Owners disputing the city's valuation of their property must instead file with the New York City Tax Commission, which will accept appeals through March.
Letters reviewed by the Post's reporters set an Aug. 21 deadline for townhouse and condominium owners to submit exemption documentation, and an Aug. 24 deadline for co-op owners – even as officials separately confirmed the tax commission's broader appeals window extends far beyond those dates, worsening the fog of homeowner confusion about which process applies to their situation.
Department of Finance Commissioner Richard Lee, addressing why the agency did not filter out more owners before mailing notices, said at a briefing last week: "We use existing information that we have, and it could have been that we don't have updated information on their applications."
A department spokesperson added that any homeowner who received a notice is encouraged to inquire or appeal if they believe their property meets the criteria for an exemption.
At least 3,800 people had started exemption applications, according to the Journal. Real estate professionals say the process disproportionately burdens older residents. Claire Groome, a Sotheby's agent, said elderly clients in particular have struggled to navigate the online exemption platform ahead of the fast-approaching deadlines.
New York already ranks 50th nationally in the Tax Foundation's 2026 State Tax Competitiveness Index, and the pied-à-terre rollout arrives as the Mamdani administration weighs additional levies on top earners to help close a projected multibillion-dollar budget gap. Against that backdrop, advisors working with clients who hold real estate in trusts, LLCs, or multi-generational ownership structures – arrangements the city said it specifically flagged notices to verify – may want to proactively review title and residency documentation before the next notice cycle.
Beyond the Empire State, firms that specialize in advisory guidance for ultra-high-net-worth families navigating tax complexity note that coordinated planning around real estate, entity structuring, and residency documentation has become increasingly important as municipalities look to real property as a revenue source.
Clients who hold New York City real estate through trusts or LLCs, in particular, should be prepared to demonstrate primary-residence status even when the underlying occupant is a family member rather than the titled owner.
