New York City Mayor Zohran Kwame Mamdani said the city has begun notifying owners of luxury second homes about its upcoming pied-à-terre tax, signaling the next step in implementing the policy.

In a post on X on Thursday, Mamdani said owners of second homes in New York City worth more than $5 million should "check your mailbox," because "you've got mail," adding that the city has sent notification letters informing property owners that the new pied-à-terre tax is "coming soon." He said the revenue would help support public services, including parks, libraries and schools.

Kathy Hochul also endorsed the rollout in a post on X, saying working New Yorkers "already do their part" and that she ensured owners of "ultra-luxury second homes" contribute more to the city.

Hochul reposted Mamdani's announcement about the notification letters, framing the tax as a way to help fund public services.
