Every Utah County parcel sits in one of the county's 151 tax areas, and each area's combined rate is the sum of every entity that taxes it: the county, the city, the school district and any special districts. This tool uses the final 2025 combined rate the Utah State Tax Commission published for the area you choose.
This is an estimate for planning, not a bill. Your parcel's assessed value and its exemption status are on the Notice of Property Valuation and Tax Changes the county mails each year.
How Utah property tax works
Each taxing entity in Utah adopts a certified tax rate meant to bring in about the same revenue as the year before, so when values rise, rates fall. An entity that wants more must hold a public Truth in Taxation hearing first. Add up every entity's rate for a parcel and you get the combined rate this tool uses. The estimate is market value, times 55% if it is your primary residence, times the combined rate.
For the tax line inside a full monthly payment, use the mortgage calculator; to start from your income instead, use the home affordability calculator. How Utah County property tax is assessed walks through the notice, the exemption application and the appeal window.
