ZIP Code 83121

In ZIP code 83121, which takes in Kemmerer, the county-level effective property tax rate sits at 0.45%. That rate applies to whatever a home is worth, so the actual bill scales with local property values rather than staying fixed. Combined with a 5.00% sales tax, the overall cost of living here depends heavily on what residents bring home and what they can afford to buy. A lower effective rate eases the yearly tax load on owners, though the final figure still hinges on income and home price together.
