Property tax snapshot

About $13–$29 per $1,000 in Westchester County

Combined full-value rate — county + town/city + school district, per $1,000 of market value (FY2025). On a $300,000 home that's about $3,933–$8,699 a year before the STAR break. A hamlet has no government of its own — it's taxed at the rates of the town it sits in.

A planning estimate, not a bill. Your exact rate depends on your school district and any village. Confirm with the assessor.
