Appeal Deadline
Grievance Day (4th Tuesday in May for most municipalities); New York City is excluded — March 1 / March 15
Most assessing units use the 4th Tuesday in May (RPTL §512); some adopt an alternate Grievance Day by local law, so confirm with your assessor. NEW YORK CITY IS EXCLUDED from Grievance Day: NYC Tax Commission applications are due March 1 for Classes 2, 3 and 4 and March 15 for Class 1. These are New York City Charter deadlines and cannot be waived or extended.
Understanding New York's Assessment Ratio
New York assesses at 100% of market value, so your assessed value should equal what your property is worth on the open market.
This makes appeals straightforward: if comparable homes in your area sold for less than your assessed value, you have grounds for an appeal.
