The Utah County property tax rate is not one number but a range: for the 2025 tax year, aggregate rates run from about 0.007235 in the lowest-rate tax areas to 0.008873 in the highest, with most addresses falling between 0.0077 and 0.0083.1Utah State Tax Commission. 2025 Tax Rates by Area Because Utah gives primary residences a 45% reduction in taxable value, the effective rate a typical homeowner pays works out to roughly 0.43% of market value, below the statewide average of 0.49%. What you actually owe depends on three things: your home’s assessed market value, whether it qualifies as your primary residence, and which combination of taxing entities serves your address.
How the Rate Gets Built
The number on your tax notice is a stack. The county, your city, your school district, and any special districts covering water, fire, or library service each set their own levy, and the Utah County Treasurer collects on behalf of roughly 46 of these entities.2Utah County Treasurer. Tax Information Every unique combination of entities produces a distinct “tax area” with its own aggregate rate, which is why rates vary across the county.
State law holds this stack in check. Under Utah Code 59-2-924, each taxing entity’s rate is recalculated annually to produce the same total revenue as the prior year, excluding growth from new construction. When property values rise, the certified rate drops to compensate. Any entity that wants to collect more than its certified rate has to go through the Truth in Taxation process, which requires a public hearing before the increase can take effect.3Utah Legislature. Utah Code 59-2-9244Utah Legislature. Utah Code 59-2-919
Finding the Rate for Your Address
Because the rate depends on your exact combination of taxing entities, the only way to get your real number is to look it up by address. The Utah County Treasurer publishes a tax rates search tool for exactly this purpose.5Utah County Treasurer. Tax Rates Search The gap between a low- and high-rate area is meaningful. A $450,000 primary residence in an area rated at 0.007529 would owe about $1,863 for the year, while the same home in an area rated at 0.008321 would owe roughly $2,059. Same value, different mix of local services, different bill.
Calculating What You’ll Owe
Once you have your tax area rate and the assessor’s market value, the math takes three steps:
- Start with the fair market value the Utah County Assessor has placed on your property.6Utah County Assessor. Utah County Assessor
- If it’s your primary residence, multiply by 0.55 to apply the 45% residential exemption. For a vacation home, rental, or commercial property, use the full market value.
- Multiply the resulting taxable value by your tax area’s aggregate rate.
A primary residence assessed at $400,000 in a tax area rated 0.008108 works out this way: $400,000 × 0.55 = $220,000 taxable value, then $220,000 × 0.008108 = about $1,784 for the year.
The 45% residential exemption, authorized by Utah Code 59-2-103, is the single biggest factor in what you pay.7Utah Legislature. Utah Code 59-2-103 – Rate of Assessment of Property – Residential Property It only applies to primary residences, so a rental property you own in Utah County is taxed on 100% of its assessed value and effectively carries nearly double the rate of your own home at the same market value. If a property’s use shifts between residential and non-residential, there’s a procedure to follow with the county to adjust the exemption status.8Utah Legislature. Utah Code 59-2-103.5 – Procedures to Obtain an Exemption for Residential Property
If Your Assessment Looks Wrong
The rate is only half of the bill. The other half is the value the assessor assigned, and that number is appealable. Under Utah Code 59-2-1004, you have until September 15 of the current year, or 45 days after you receive the auditor’s valuation notice, whichever is later, to file an appeal with the county board of equalization.9Utah Legislature. Utah Code 59-2-1004 – Appeal to County Board of Equalization
Your application needs your own estimate of fair market value and evidence supporting it. The strongest evidence is a recent purchase price, a professional appraisal with an effective date within one year of January 1, or documented sales of comparable properties nearby. If the board finds your valuation deviates more than 5% from comparable assessed properties, it must bring your valuation in line. The appeal costs nothing to file, and a successful one keeps the lower value on the books for as long as you own the home.
Relief That Lowers the Bill Further
Utah has several programs that reduce property tax bills beyond the residential exemption, but none of them apply automatically. You have to file.
Homeowner’s Credit (Circuit Breaker)
This is a credit for lower-income households. For 2026, the maximum is $1,412 for homeowners with household income of $15,033 or less, scaling down through income brackets and phasing out above $44,221. Homeowners apply through the county; renters file through the Utah State Tax Commission.10Utah State Tax Commission. Homeowner’s or Renter’s Relief
Disabled Veteran Exemption
A veteran with a service-connected disability rating of 10% or higher from the VA receives an exemption on the primary residence, proportional to the disability percentage, applied against taxable value up to a limit currently around $521,620. Veterans the VA classifies as individually unemployable are treated as 100% disabled regardless of their stated rating. Surviving spouses and minor orphans of service members killed in action or who died in the line of duty receive an exemption covering the full taxable value of the primary residence.11U.S. Army. Utah Military and Veteran Benefits
Active Duty Exemption
Service members stationed outside Utah for at least 200 days in a continuous 365-day period receive a full exemption on their primary residence. You must be the owner of record as of January 1 and file by September 1 with your orders. The exemption has to be reapplied for each qualifying year.11U.S. Army. Utah Military and Veteran Benefits
Deferral for Elderly Homeowners
Homeowners 75 or older can defer their property taxes rather than paying them annually. The deferred amount accrues interest but no delinquency penalties. Qualifying requires 2024 household income of $85,246 or less, no existing delinquent taxes, use of the property as your primary single-family residence, and written approval from any mortgage or trust deed holder. The deadline is September 1, with annual renewal.12Utah State Tax Commission. Pub 36
Indigent Abatement
Homeowners 65 or older, or those with a disability or extreme hardship, may qualify for an abatement of up to 50% of the remaining bill after other relief has been applied, capped at the same amount as the homeowner’s credit ($1,412 for 2026). Income limits apply, and the home must be your primary residence. File by September 1 through the county.
Paying On Time
Tax notices go out around the third week of October, and payment is due in full by November 30. A U.S. Post Office postmark counts as proof of timely mailing; an office postage meter stamp does not.2Utah County Treasurer. Tax Information You can pay online, by mail, or in person at the county administration building. Electronic checks carry no processing fee, while credit and debit cards are charged a 2.65% convenience fee, with Visa debit cards taking a flat $3.95 instead.13Utah County Treasurer. Pay Taxes Online On a $2,000 bill, the card fee runs about $53, so an electronic check is the cheaper way to pay online.
If you have a mortgage, your lender probably pays the county from an escrow account built into your monthly payment. Verify that it’s actually happening on time. The county holds the property owner responsible for delinquent taxes regardless of any escrow arrangement.
Missing November 30 triggers an automatic penalty of 2.5% of the unpaid amount, or $10, whichever is greater. If you pay everything owed, plus the penalty, by January 31, the penalty drops to 1% (or $10 minimum). After January 31, interest begins accruing retroactively from January 1 at a rate equal to 6% plus the federal funds rate target as of that January 1, with a floor of 7% and a ceiling of 10%.14Utah Legislature. Utah Code 59-2-1331 At current federal funds rates, delinquent taxpayers typically hit the 10% cap.
