NYC property-tax due dates are not one-size-fits-all

New York City property-tax timing is easy to misremember because bills are not all billed the same way. NYC Finance says some properties are billed quarterly and others semi-annually, with due dates tied to assessed value. Before a closing, refinance, co-op board budget, or homeowner payment plan, check the official DOF bill and due-date pages, then save the current bill.

Do not rely on the seller’s calendar memory or on a generic “taxes are due twice a year” assumption. The next practical check is the Borough-Block-Lot and the bill schedule for that exact property. Timing affects escrow, penalties, and closing adjustments.

Keep the current DOF bill, Borough-Block-Lot, assessed value, billing schedule, due dates, escrow figures, closing adjustment, and payment receipt together. Use that property’s schedule rather than a general twice-a-year assumption.
