Mark Penn's Fox News op-ed makes a clean, quotable charge: New York City's new pied-a-terre tax was pitched as a levy on the ultra-wealthy and will instead land on ordinary homeowners. "The Department of Finance's initial roll sent notices to 960,000 property entries," Penn writes, against an original pitch of "no more than 31,000" [1]. He argues the surcharge "can reach up to 5% or more of market value annually," and that it will "chill the broader housing market, reduce demand from out-of-town buyers and ultimately drag down property values across the board," leaving "local homeowners" to "pay the price through diminished equity" [1].
That is framing, and it belongs in the opinion column where it ran. The reason to set the record beside it is not to rate the argument true or false. It is that the single number carrying the whole claim, 960,000, is not what it is being used to mean.
The 960,000-record file is the Department of Finance's unfiltered full property roll, published to satisfy a state-law transparency requirement [3]. It is a list of properties, not a list of taxpayers. When Hell Gate filtered that roll down to the properties that actually meet the enacted tax's thresholds, the eligible universe came to about 24,300, roughly 17,500 condos and co-ops plus 6,800 homes [3]. That is close to the low end of the debate, not forty times above it.
The enacted statute is more specific than either side's headline number. In Phase 1, which runs through June 30, 2028, condos and co-ops owe the surcharge starting at $1M assessed value, in tiers of 4%, 5.25% and 6.5%, while one-to-three-family homes owe it only starting at $5M market value [2]. From 2028, Phase 2 moves both categories to a $5M threshold [2]. The steel-man for Penn's alarm is real on its own terms: a public, searchable file with 960,000 entries invites exactly the reading that a million households are on the hook, even though the file is a transparency roll rather than a bill.
The wrinkle that most coverage skips runs in the other direction. Defending the searchable database, Mamdani said the administration is "committed to ensuring that this is a tax only levied upon those whose second homes are worth more than five million dollars" [4]. That $5M line is the number the mayor wants remembered. It does not match his own Phase-1 statute, which sets the condo and co-op threshold at $1M assessed value [2]. Penn inflates the reach by reading the raw roll as a taxpayer list; Mamdani understates it by naming only the higher threshold.
What is left, once both numbers are placed on the table, is narrower and more useful than the viral version. The pied-a-terre surcharge reaches an eligible universe of roughly 24,300 to 31,000 properties, at tiered rates that start at $1M assessed value for condos and co-ops and $5M market value for houses in the first phase. A reader can decide for themselves whether that is a billionaire tax, a broader one, or something in between. The one thing the 960,000 figure cannot tell them is who owes it.
