Nassau County Property Tax Calculator
Nassau County stands apart from most of New York in doing assessment at the county level: the Nassau County Department of Assessment values every property annually rather than leaving it to individual towns. Nassau shows up often on lists of the nation's highest-median-bill counties, though eligible owner-occupants can still claim statewide STAR relief on the school-tax portion. Nassau County can be selected above; pair it with a home value for a projected bill.

Property tax in Nassau County, New York
- The Nassau County Department of Assessment values property countywide, unlike most New York counties where individual towns handle assessment.
- STAR, New York's statewide relief program, knocks down the school-tax slice owed by an eligible owner-occupant, arriving either as an exemption or a rebate check.
- Owners can challenge an assessment by filing an administrative review, and if unresolved, further appeal through small claims assessment review or the courts.
- Nassau shows up often on lists of the country's priciest median bills, a product of strong home values layered with the cost of a dense mix of local governments.

Frequently asked questions
How is property tax calculated in Nassau County?
The Nassau County Department of Assessment fixes a countywide assessed value each year, and school districts, towns, villages, and special districts each layer a separate charge on top. STAR relief further reduces the school levy owed by an eligible owner-occupant.
How do I appeal my Nassau County assessment?
An administrative review through the Department of Assessment during the annual filing window is the first step; small claims assessment review or judicial review through the courts follow if the disagreement continues.
Does Nassau County offer STAR or homestead relief?
Yes — an eligible owner-occupied home in Nassau receives New York's STAR relief, cutting the school-levy portion of the bill, and additional exemptions exist for seniors, veterans, and other qualifying owners.
Why does Nassau County have some of the nation's highest property tax bills?
High home values combined with the cost of funding a dense mix of school districts, towns, and villages push Nassau's median bills near the top of national rankings, a pattern shared with several of its downstate New York neighbors.
