The New York City Department of Finance (DOF) targets roughly 17,000 property owners for the non-primary residence property surcharge (often referred to as the "pied-à-terre tax") through automated data matching across municipal, state, and tax records rather than random selection.
The selection process relies on key criteria and tax cross-checks:
The DOF first filters properties based on assessed market value for the current tax year:
The DOF compares property registration addresses with New York State and New York City income tax filings:
DOF cross-checks database records for property tax relief programs like the Co-op/Condo Tax Abatement or STAR exemption, both of which require the owner to reside in the unit as their primary residence:
Properties held under corporate entities, LLCs, trusts, or partnerships that do not have a designated primary resident or majority-interest owner on record with the city automatically receive a notice to verify whether the unit is occupied by a qualifying resident or tenant.
Receiving a notice does not mean you automatically owe the tax. Owners who use the home as a primary residence, rent it long-term to a tenant, or house an immediate family member can submit proof—such as state tax returns, a New York driver's license, voter registration, or a active lease—via the online DOF portal to claim an exemption.
