Nassau County's taxing jurisdictions range in size from the county itself to towns, cities, villages, local school districts, library districts and other special districts providing specific services to people in their boundaries. Of course, you only pay taxes in a few of them, the exact number varies depending on where you live.
With the exception of cities and those villages which establish their own tax rolls for city and village purposes, each year these taxing jurisdictions examine the assessment roll prepared by the Department of Assessment and establish budgets which determine the tax levy (amount of money to be raised by property taxes).
Taxes for village or city purposes and for school purposes are billed separately. The tax rates for all the other taxing jurisdictions in which your property is located are added together and that consolidated tax rate (per hundred) multiplied by the assessment of your property equals your property tax for county, town and special district purposes.
