Westchester is the only county in New York State with a AAA rating from two rating services. The
Westchester County Budget Office serves as staff to the
County Executive and the County
Board of Legislators on budget issues. The department prepares the annual operating budgets and capital budgets for the county and its four water districts, 11 sewer districts and one refuse disposal district, as well as for Westchester Community College. The county is on a Jan. 1 to Dec. 31 fiscal year. By November, the County Executive proposes a budget; and by the end of December, it is adopted by the Board of Legislators.
County taxes account for between 15–20% of a total property tax bill. The remainder of taxes are levied by school districts and local governments.
