Town of Hempstead, Town of North Hempstead, and the Town of Oyster Bay
Your property assessment is the basis of your property taxes.
If you live in the township of Hempstead, North Hempstead or Oyster Bay, your property's assessment is set by Nassau County, rather than by the township in which you live.
As such, if you live in Nassau County and you want to file a grievance about your property's assessed value, you must file your grievance with the "Assessment Review Commission" or "ARC."
The following statements were excerpted from the Nassau County Government website:
"ARC is an independent agency, separate from the Nassau County Department of Assessment. We are responsible for annually reviewing all applications for correction of assessment filed in Nassau County."
"Our mission at ARC is to review the valuation set by the Department of Assessment and to reduce the assessment if the valuation is excessive. Over the past seven years, ARC has corrected assessments on over 200,000 residential properties and on over 22,500 commercial properties. These corrections have resulted in substantial savings to you, the taxpayer."
