Property tax snapshot

About $3–$27 per $1,000 in Suffolk 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 $800–$8,201 a year before the STAR break. A village is assessed within its town; expect the town's rate plus a separate village tax.

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