At about $22,982 a year, this home's property tax runs roughly 155% above the $9,000 typical for Westhampton Beach Union Free School District. Suffolk bills combine town, school and special-district levies, so two homes at the same price in neighboring districts can carry materially different taxes. Exemptions such as STAR, Senior or Veteran move the number as well — a new owner's bill is often not the same as the seller's.
