Mohawk Valley
South Ilion, New York
South Ilion is a hamlet — a community without a village government of its own — in Herkimer County, part of New York's Mohawk Valley region, with about 119 residents at 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.

About $8–$37 per $1,000 in Herkimer 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 $2,322–$11,190 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.

Good to know
- • Your assessed value usually isn't your market value — ask for the equalization rate.
- • Register for STAR; new applicants generally receive a credit instead of an automatic exemption on the bill.
- • Outside the cities, check the well, the septic, and the FEMA flood map before you buy.
