Property Tax in Nassau County

Nassau County's low rate masks suburban wealth
Nassau County's effective tax rate of 1.518% sits well below the national median of 2.1%, placing it in the bottom third of U.S. counties by rate—but the typical homeowner still pays $10,001 annually, nearly four times the national median of $2,690. This paradox reflects the county's extraordinarily high median home value of $658,700, among the highest in the nation.
Lowest rate in New York, highest bills
Nassau County's 1.518% effective rate is the lowest among New York's 62 counties, well below the state average of 2.046%. Yet the median tax bill of $10,001 far exceeds the state average of $4,709, a clear illustration of how property values, not just rates, determine your actual tax burden.
Rates low; bills among the nation's highest
Nassau's 1.518% rate beats nearby New York County (0.902%) and significantly undercuts upstate peers like Lewis County (1.698%). However, Nassau homeowners pay $10,001 annually—double what Monroe County residents pay despite Monroe's much higher rate, because Nassau home values dwarf the region's.
What a typical Nassau County home costs to own
On Nassau's median home value of $658,700, you'll pay approximately $10,001 in annual property taxes at the current effective rate. This substantial bill reflects the county's position as a prosperous Long Island suburb where real estate values run among the nation's highest.
You may be overassessed—here's what to do
Across New York, many homeowners discover their assessed values exceed fair market value, opening the door to successful tax appeals. If you believe your Nassau County property is overvalued relative to recent sales of comparable homes, filing a grievance during the assessment review period could provide substantial savings on your already substantial annual bill.
