How Ketchum property tax is calculated
Your assessor sets Ketchum's assessed value, and local millage rates from the city, county and school district are applied to it; the 0.52% effective rate rolls all of that into one share of market value. To estimate your tax, multiply your home value by 0.52% (or your exact local rate), then subtract any homestead or senior exemption you qualify for. The calculator above does this and shows both the annual bill and the monthly escrow amount.
