New York City homeowners are encountering difficulties as they attempt to comply with the newly implemented pied-à-terre tax, which places the burden of proof on property owners to demonstrate primary residency in order to avoid hefty surcharges.

Karen Young, a longtime Upper West Side resident and founder of a beauty-marketing company, described her experience trying to submit documentation verifying her brownstone as her primary residence. Despite spending hours navigating the city’s new online system, Young found that uploaded documents failed to save, forcing her to restart the process. Additionally, she must obtain an ownership title from her estate lawyer, incurring extra costs just to participate in the verification procedure.

Homeowners subject to this tax must provide proof by August 21 to avoid a $42,824 surcharge on their January 2027 property tax bills. The tax, formally named the “Surcharge on Property That Does Not Serve as a Primary Residence,” was introduced to target wealthy individuals owning unoccupied secondary properties in the city. However, the process to establish residency has proven onerous and confusing for many families, including those who genuinely live in their homes year-round.

Young stated that despite receiving jury summonses, paying taxes, and maintaining utilities at her address, she struggles with the requirement. The city’s Department of Finance published an extensive database identifying over 960,000 properties and owners potentially subject to the tax, leading to widespread alarm among residents unsure of their status.

The legislation received bipartisan criticism, with James Whelan, president of the Real Estate Board of New York, expressing concern that the city was unprepared to manage the complex administration of the tax. Whelan noted that inaccurate tax notices have been widely distributed, further complicating compliance.

The law, signed by Governor Hochul in May, targets one- to three-family homes valued at $5 million or more, as well as co-ops and condominiums worth at least $1 million that are not used as primary residences. Homeowners who believe they have been wrongly assessed can file appeals.

Some experts have characterized the legislation as poorly constructed. Donna Olshan, a broker specializing in luxury residences, described the statute as “full of holes,” pointing to flaws in its legal drafting and execution.

As the deadline approaches, many New Yorkers face an urgent scramble to gather and submit proof for their residency status, amid concerns that the tax’s implementation will continue to pose challenges for both homeowners and city officials.
