 2011-2012 Nanuet School District Tax Increase Explanation

MISSION: To provide fair and equitable valuations to all properties for tax purposes.

EXPLANATION: The assessor assigns a dollar value for each property, whether vacant, improved, residential, or commercial within the Town.  This assessed value is then used as a multiple to calculate each year's tax burden for town, county and school purposes.  For example:


$200,000      a/v  (assessment of a residence)

X .015445     (the town tax or mill rate per $1,000 of assessed value)

$3,089.00     (indicated town tax)

Other related duties of the Assessor:

  • Comply with provisions of NYS Real Property Tax Law:
  • Provide and compile all applications for various NYS exemptions for real property:
  • Calculate and implement Article 19 of RPTL - The Homestead Provision (an apportionment process to determine the percent tax burden shared by the residential and commercial classes of properties);
  • Insure that the proper yearly Equalization Rate issued to the town for county, school and state aid apportionment purposes by New York State is based on reasonable sales and appraisals and if challenged, to provide the necessary basis on which to have the rate recalculated;
  • Provide general assessment information to the Town Board and citizens, especially concerning yearly changes in the law or rules and procedures;
