Overview of Where Your Taxes Go

The Office of the Receiver of Taxes is not a policy making office, it is an administrative office. We do not determine the tax rates, we merely collect and distribute the taxes. Taxes are collected in accordance with New York State Real Property Tax laws and the Suffolk County Tax Act.

Town, County and School taxes in Suffolk County cover the period from December 1st through November 30th of the following year. Public Hearings are set for school, county and town budgets. Below is a description of how your taxes are divided up.

School Taxes:
School budgets are set by your local school districts. Every year you have the opportunity to vote on the school budget. This determines the amount of taxes you will pay for schools in your district.

County Taxes:
County Taxes are set by a county budget, approved by the County Executive and the Suffolk County Legislature.

Town Taxes:
Town Taxes are set by a town budget, approved by the Supervisor and Town Board. 

Other Taxes:
Taxes for other districts - (Fire, Ambulance, etc.) are also collected by this department.
