What the statewide pattern does—and does not—tell you

Repeated guidance can reveal a common state calendar, but a county notice, local ordinance, installment schedule, or special program can still control an individual property. The entries below are shown only when the same reviewed wording appears in at least two New York records.

Payment timing

Appears in 2 records

Quarterly bills are due July 1, October 1, January 1, and April 1; semiannual bills are due July 1 and January 1. The interest-free grace date for quarterly payments is the 15th of the month.

Assessment protest

May 26, 2026 (the fourth Tuesday in May) is the standard New York Board of Assessment Review grievance day; local municipalities may publish alternate 2026 dates. File Form RP-524 with the applicable local assessor.
