New York City recently published a detailed list of 31,000 properties that could owe a newly introduced luxury tax. This number far exceeds officials' initial estimate of 10,000 homes, revealing a much wider scope than expected.

The tax, effective from July 1, targets second homes where owners do not primarily reside. Properties must meet minimum values to be included: condominiums and co-ops starting at $1 million, and houses at $5 million. The lower threshold for apartments explains why 24,700 units made the list, compared to just 6,800 houses.

State law required the city to identify each property that might be liable, including exact street addresses and apartment numbers for co-ops, not just building names. That means entire buildings often appear on the list, not only individual units.

Ben Williams, a property tax lawyer who testified on the rules, criticized the list as overly broad and expects many properties to be removed after appeals. Billing statements for the tax will be sent by August 30, with owners given 30 days to contest if they qualify for exemptions. The final roster is due by the end of December.

Privacy Concerns Spark Debate Among Crypto Leaders

Prominent figures in the crypto world have voiced alarm. Hayden Adams, founder of Uniswap, described the list as a mass doxxing, noting that nearly every unit in luxury towers was included, not just those known to be owned by affluent individuals.

Helius CEO Mert Mumtaz acknowledged the data was public but stressed that the new list is much cleaner and easier to access, making it a targeted collection of wealthy residents. He pointed out the disturbing trend of diminishing privacy for the rich.

Investor Nic Carter referenced recent crypto-related kidnappings in Europe, warning that publicly sharing home addresses of wealthy crypto owners could increase risks of targeted crimes.
