How values have moved

Reading these figures
A median describes Williston Park, not your home, which may sit well above or below it for good reasons. The tentative roll can still change before it becomes final. Recorded payments are not a tax bill: exemptions and special districts vary by home. This page summarizes published records and is not an appraisal; verify any figure that matters in the Nassau County Land Records Viewer, and see how these pages are built.
Common questions
How are homes in Williston Park assessed?
Nassau assesses one-to-three family homes at the same small fraction of County market value across the county. In Williston Park, the median assessed value is $646, which is 0.1% of market value. Your tax bill is calculated from assessed value.
How do I file a property tax grievance in Williston Park?
File with Nassau County’s Assessment Review Commission (ARC), online or on paper, during the published window of January 4–March 1, 2027. Filing is free, needs no attorney, and the County states a grievance never raises an assessment. ARC reviews the assessment behind county, town, and school taxes. Homes inside the Village of Williston Park also pay village taxes on the village’s own assessment, which has a separate grievance with the village, usually in February; an ARC filing does not cover it.
