The 50 highest estimated property tax bills in New Castle
These are the 50 residential parcels in New Castle with the highest estimated annual property tax. Each estimate applies county, school, and village mill rates for fiscal year 2026 town & county / 2026-27 school to the parcel's assessed value. The median estimated bill in New Castle is $23,018.
These are estimates. They leave out sewer, refuse, and special district charges, and they apply STAR only where the roll shows an exemption code. A property whose exemptions changed during the year, or one with a district charge, will not match its bill. Treat the dollar amounts as approximate, and confirm any figure that matters with the official source.
