NYC Pied-à-Terre Tax Exemption Deadline Extended

NYC extends the pied-à-terre tax exemption deadline to September 18, giving property owners more time to prove primary residency and avoid the new surcharge.

Mayor Mamdani gives NYC homeowners nearly a month of extra time to file exemption claims

NEW YORK — New York City homeowners who received notices about the city's new pied-à-terre tax have been granted more time to prove their primary residency status. Mayor Zohran Mamdani and Department of Finance Commissioner Richard Lee announced the exemption application deadline has been extended from August 21 to September 18, 2026.

The city's finance department said the extension was necessary to give homeowners more time to prove that their home is their primary residence, which would mean the tax would not apply to them.

The pied-à-terre tax, passed by the New York State Legislature and signed into law in May 2026, imposes an annual surcharge on certain high-value New York City homes worth more than $5 million that are not the owner's primary residence.

On July 22, 2026, the DOF began mailing notices to owners of New York City residential properties for which its records did not establish primary-residence status. Each notice contains a website link and a personalized PIN, which must be used to file an exemption claim electronically.

Some homeowners were initially confused because the city published a list of more than 900,000 properties in a "supplemental market value roll" without explaining that the vast majority of them would not be getting hit with the pied-à-terre tax.

"We are announcing the extension of the exemption application deadline to ensure that New Yorkers who received the 'You may be subject to…' letters have the time and information they need," Mayor Mamdani said.
