Hudson Valley

Thompson, New York

Thompson is a town in Sullivan County, in New York's Hudson Valley region, home to about 16,500 people as of the 2020 census.

Like the rest of upstate New York, an assessed value here usually isn't the market value; the state's equalization rate reconciles the two. The local rate is below, and the STAR program can lower the school-tax part of the bill.

Property tax snapshot

Roughly $20–$24 per $1,000

Combined full-value rate — county + town/city + school district, per $1,000 of market value (FY2025). On a $300,000 home that's about $6,125–$7,166 a year before the STAR break.

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