- New York City Mayor Zohran Mamdani's administration introduced a property tax surcharge on second homes, targeting high-value properties with a searchable online database of affected owners.
- The surcharge applies to single-, two-, and three-family homes valued over $5 million and condos/co-ops valued over $1 million, with rates ranging from 0.8% to 6.5% of market value.
- Critics argue the database, while based on public records, is unusually packaged and singles out individuals for public scrutiny, potentially making them feel unsafe and unwelcome.
- Mamdani previously named hedge fund CEO Ken Griffin as a tax target, and the tax may affect properties worth less than the average in some boroughs, contradicting claims it targets only the 'richest of the rich'.
- Many affected owners may be wrongly identified due to outdated information, as admitted by city officials, leading to errors like an 81-year-old woman being taxed on her primary residence.
- The implementation has drawn criticism from even some supporters, who compare it to a 'wanted poster' and note the dangerous precedent of class-based targeting in a city where a CEO was recently assassinated.
- The tax is seen by detractors as fostering class resentment and punishing success, rather than addressing genuine tax needs.
