UPPER WEST SIDE, Manhattan (PIX11) — Tuesday will be a major test for Mayor Zohran Mamdani’s pied-à-terre tax. 

The City Council is holding an oversight hearing after the rollout sparked confusion among thousands of New York City homeowners and a lawsuit that temporarily put the tax on hold.

The big question is not necessarily whether the city should tax expensive second homes, but whether the city properly handled the rollout of this tax.

Pied-à-terre was a plan to make New York’s wealthiest pay more, but the rollout has so far caused considerable confusion.

The Department of Finance sent letters to roughly 17,000 property owners identified as potentially subject to the tax. Still, it also published a much larger list of hundreds of thousands of properties, leaving many homeowners wondering why they were included and whether they actually owe anything.

The City says the vast majority of those properties will not be subject to the surcharge.

Homeowners who received a notice can apply for an exemption if the property is their primary residence.

The confusion has already led to a lawsuit and, last week, a temporary pause in the rollout.

On Tuesday, council members want answers about how the Department of Finance identified these properties, how homeowners were notified, and how the city plans to fix the confusion.

The exemption deadline is now September 18.
