How this ranking works
Ranked by median residential property tax bill from the latest New York State assessment roll. For each district, the median bill is the per-parcel projection (full market value × combined county, town and school rate ÷ $1,000) taken across every residential parcel, so districts that span several towns use each parcel’s own rate. Village, library and special-district levies are excluded.
District rankings leave out tiny elementary-only districts with fewer than 1,500 parcels. Families there pay tuition elsewhere for the upper grades, so their bills aren’t comparable.
