Apply to be featured →Ranked by median residential property tax bill from the latest NY State Office of Real Property assessment roll. For each district, the median bill is the per-parcel projection (FMV × combined county+town+school rate ÷ $1,000) medianed across all residential parcels — so multi-town districts use each parcel's actual local rate. Excludes village, library, and special-district levies. District rankings exclude tiny K-6 elementary-only districts under 1,500 parcels (those families pay tuition elsewhere for upper grades, so the bill isn't comparable).
