Bills here run lower partly because homes are worth less. That alone doesn’t mean anyone is over-assessed: what counts is how your home compares with similar homes in Roslyn.

Home values in Roslyn

Reading these figures
A median describes Roslyn, 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 Roslyn School District assessed?
Nassau assesses one-to-three family homes at the same small fraction of County market value across the county. In Roslyn School District, the median assessed value is $502, which is 0.1% of market value. Your tax bill is calculated from assessed value.
How do I file a property tax grievance in Roslyn School District?
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.

Understanding your Nassau County assessment
Market value, assessed value and your bill measure different things. A grievance argues the value behind your assessment is too high.
Choosing comparable sales
Homes like yours in size, type, location and condition. A neighbor’s lower tax bill isn’t evidence.
