How values have moved
Imported rolls cover only one year so far, so this uses the year-by-year values on the County’s own record pages for the 90 homes in Port Washington whose records we have retrieved. That is a sample, not every home, so its medians differ from the figures above.

Reading these figures
A median describes Port Washington, 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 Port Washington assessed?
Nassau assesses one-to-three family homes at the same small fraction of County market value across the county. In Port Washington, the median assessed value is $862, which is 0.1% of market value. Your tax bill is calculated from assessed value.
How do I file a property tax grievance in Port Washington?
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.
