Reading these figures
A median describes Old Westbury, 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 Old Westbury assessed?
Nassau assesses one-to-three family homes at the same small fraction of County market value across the county. In Old Westbury, the median assessed value is $1,686, which is 0.1% of market value. Your tax bill is calculated from assessed value.
How do I file a property tax grievance in Old Westbury?
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. The Village of Old Westbury bases its village assessments on the County’s values but still reviews them itself, so ask the village clerk whether it holds a grievance day.
