Reading these figures
A median describes Cold Spring Harbor, not your home, which may sit well above or below it for good reasons. The tentative roll can still change before it becomes final. 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 Cold Spring Harbor assessed?
Nassau assesses one-to-three family homes at the same small fraction of County market value across the county. In Cold Spring Harbor, the median assessed value is $797, which is 0.1% of market value. Your tax bill is calculated from assessed value.
How do I file a property tax grievance in Cold Spring Harbor?
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. If your home is in an incorporated village that sets its own assessment, the village holds a separate grievance, usually in February.
