Utah property tax is charged each year on the fair market value of real estate and business personal property as of January 1, with owner-occupied homes taxed on only 55% of that value thanks to a built-in 45% residential exemption. Payment is due November 30 to the county treasurer where the property sits, and the money funds local schools, cities, counties, and special districts rather than the state’s general fund. Rates are set by each overlapping taxing entity and controlled by a mechanism that keeps rising home values from automatically pulling more revenue out of your pocket.
How Your Property’s Value Is Set
Every county assessor places a fair market value on each parcel and its permanent structures as of January 1. Utah Code defines fair market value as the price a property would bring between a willing buyer and a willing seller, where neither is under pressure and both have reasonable knowledge of the relevant facts.1Utah Legislature. Utah Code 59-2-102 – Definitions Assessors work from recent sales data, construction costs, and, for commercial parcels, income potential.
The valuation uses current zoning unless there is a reasonable probability that zoning will change during the tax year and that change would meaningfully affect the property’s worth.1Utah Legislature. Utah Code 59-2-102 – Definitions If you own land near a recently approved development or in an area the county is considering rezoning, the assessor may factor the expected change into your value.
Business owners have a separate obligation. Equipment, machinery, and furniture used in a business must be reported to the county assessor each year on a signed personal property statement, typically by mid-May, and those filings are subject to audit.
The 45% Residential Exemption
If a home is your primary residence, Utah taxes only 55% of its fair market value. The exemption is built into the assessment rate itself: residential property is assessed at 55%, all other property at 100%.2Utah Legislature. Utah Code 59-2-103 – Rate of Assessment of Property – Residential Property In most counties the exemption applies automatically once the property is classified owner-occupied, though some counties require an application through the county board of equalization.3Utah Legislature. Utah Code 59-2-103.5 – Procedures to Obtain an Exemption for Residential Property
A home with a $500,000 fair market value is taxed on $275,000. A commercial building worth the same $500,000 is taxed on the full amount. If you convert the home to a rental or another non-residential use, the exemption goes away and the county reclassifies the property at full value.
How Tax Rates Get Set
Your bill is not the work of a single agency. Multiple taxing entities overlap on every parcel: the county, the school district, the city or town, and any special service districts for services like fire protection or mosquito abatement. Each entity sets its own rate, and the rates are added together and applied to your taxable value.
Utah caps how much revenue those entities can collect through what is called the certified tax rate. Each year the rate is recalculated so that if property values rise across a taxing district, the rate drops enough that the entity collects roughly the same total revenue as the prior year, plus revenue from new construction.4Utah Legislature. Utah Code 59-2-924 – Calculation of Certified Tax Rate Rising home prices alone should not push up your bill, as long as your home appreciated at about the same pace as everything else in the district.
If a school district or city wants to collect more than the certified rate would allow, it cannot quietly raise the rate. The entity must publicly announce its intent, advertise the proposed increase in both dollars and percentage, and hold a public hearing before the vote.5Utah Legislature. Utah Code 59-2-919 – Notice and Public Hearing Requirements for Certain Tax Increases This process, known as Truth in Taxation, applies to any proposed rate above the certified rate.
Key Dates in the Property Tax Year
- January 1. The lien date. Your property’s fair market value is fixed as of this date for the whole tax year.
- May 15. Deadline for businesses to file personal property declarations with the county assessor.
- July to August. Valuation notices are mailed, showing assessed value and any proposed rate changes. This is your starting point if you plan to appeal.6Utah State Tax Commission. Property Valuation Appeal Process
- September 15 (or later). Deadline to file a valuation appeal with the county board of equalization. If the valuation notice was mailed late, you have 45 days from the mailing date, whichever is later.7Utah Legislature. Utah Code 59-2-1004 – Appeal to County Board of Equalization
- November 30. Property taxes are due. Any payment made or postmarked after this date is delinquent.8Utah Legislature. Utah Code 59-2-1331 – Property Tax Due Date – Penalty – Interest
Paying Your Bill
County treasurers accept payments online, by mail, and in person. Online portals let you look up your balance by parcel number or address and pay by electronic check or credit card. A mailed check must be postmarked by November 30 to count as timely.
If you have a mortgage with an escrow account, your lender usually requests the tax amount from the county and pays on your behalf close to the deadline. Your tax notice may show the mortgage company’s name, but that only means the company asked for the amount owed. Confirming the payment actually posted is still your responsibility, and your lender’s year-end statement should show the disbursement.
Penalties and Interest for Late Payment
Miss November 30 and the cost climbs in stages. If you pay everything owed, including the penalty, by January 31 of the following year, the penalty is 1% of the delinquent amount or $10, whichever is greater. If the balance is not cleared by January 31, the penalty rises to 2.5% or $10, whichever is greater.8Utah Legislature. Utah Code 59-2-1331 – Property Tax Due Date – Penalty – Interest
Interest starts on January 1 following the delinquency date. The rate equals 6% plus the federal funds target rate on that January 1, with a floor of 7% and a ceiling of 10%, and it compounds annually for each year the delinquency continues.8Utah Legislature. Utah Code 59-2-1331 – Property Tax Due Date – Penalty – Interest On a $3,000 tax bill still unpaid past January 31, you would owe at least $75 in penalty plus 7% or more each year on the full balance. Left long enough, the debt can cost you the property.
Programs That Reduce or Defer What You Owe
Utah runs several relief programs through the county auditor. Each has its own eligibility rules and its own application.
Circuit Breaker Credit
The Circuit Breaker gives a direct credit against property taxes to lower-income older homeowners (the age threshold sits at 66 or 67 depending on the program year) and qualifying surviving spouses of any age. The credit amount depends on prior-year household income. For 2026, the maximum credit is $1,412 for homeowners with 2025 household income of $15,033 or less, and the credit phases out entirely above $44,221.9Salt Lake County. Circuit Breaker Tax Abatement Relief Apply through your county auditor and bring documentation for every income source.
Disabled Veteran Exemption
Veterans with a service-connected disability of at least 10% can exempt a portion of their home’s taxable value. The exemption equals the disability percentage times an adjusted taxable value limit that rises with inflation. A veteran the VA has classified as individually unemployable is treated as having a 100% rating. Surviving spouses of veterans killed in action or who died in the line of duty receive a full exemption on the home’s taxable value. New applicants submit a current letter from the Department of Veterans Affairs or a branch of service verifying the disability percentage.
Blind Exemption
Legally blind residents can exempt up to $11,500 in taxable value from taxation.10Utah State Tax Commission. Pub 36 – Property Tax Exemptions for Individuals First-time applicants file a statement from a licensed ophthalmologist confirming corrected vision of 20/200 or worse in the better eye, or a field of vision restricted to 20 degrees or less.11Utah State Tax Commission. Blind Persons Property Tax Exemption Application After the first year, the medical verification does not need to be refiled unless circumstances change.
Senior Deferral
Homeowners 75 or older who meet income and asset limits can defer property tax rather than paying it each year. For 2026 eligibility, 2025 household income must be under $88,442 and liquid assets must be less than 20 times the annual tax amount. The home must be the applicant’s primary residence as of January 1, and its market value generally cannot exceed the county’s median for single-family homes unless the owner has lived there continuously for at least 20 years. Deferred taxes become a lien on the property and are repaid when the home is sold or transferred.
Appealing Your Assessment
If you think the assessor overvalued your property, file an appeal with the county board of equalization by September 15, or within 45 days of the mailing date on your valuation notice, whichever is later.7Utah Legislature. Utah Code 59-2-1004 – Appeal to County Board of Equalization Most counties accept filings online. Bring evidence: a recent independent appraisal, sales data for comparable homes nearby, or documentation of defects the assessor could not see from the outside. The board reviews the evidence, holds a hearing, and issues a written decision with the final assessed value.12Legal Information Institute. Utah Admin Code R884-24P-66 – County Board of Equalization Procedures and Appeals
If the county rules against you, you have 30 days from the date on the county’s decision to escalate to the Utah State Tax Commission by filing form TC-194, Request for Redetermination, with the county auditor.13Utah State Tax Commission. Appeals of Locally Assessed Property The Commission’s appeals unit schedules either a mediation conference or an initial hearing.
Farmland Assessment (Greenbelt)
Agricultural land can be assessed at its value for farming rather than its fair market value, a break that can cut the tax bill sharply on working farms near growing cities. To qualify under the Farmland Assessment Act, land must be at least five contiguous acres, actively devoted to agricultural use, and farmed for at least two consecutive years before the tax year in question.14Utah Legislature. Utah Code 59-2-503 – Farmland Assessment Act Smaller parcels can qualify if farmed alongside other eligible land under identical ownership, and the land must produce more than 50% of the average agricultural output per acre for its type and county.
Pulling land out of agricultural use triggers a rollback tax equal to the difference between what was paid under the agricultural assessment and what would have been paid at market value, going back up to five years.15Utah Legislature. Utah Code 59-2-506 – Rollback Tax The owner must notify the assessor within 120 days of the change in use, and the rollback tax is due within 60 days of the assessor’s notice. Missing the notice triggers an added penalty of 2% of the last year’s rollback tax or $10, whichever is greater.
What Happens If Taxes Go Unpaid
Unpaid property taxes do not sit forever. After four years of delinquency, the county can sell the property at a public tax sale, typically held in May or June.16Utah Legislature. Utah Code 59-2-1346 – Redemption of Property Before Tax Sale The owner can redeem the property at any time before the sale begins by paying all delinquent taxes, penalties, interest, and administrative costs in full. Partial payments do not stop a sale, and by law payments apply to the most recent tax year first, so the oldest delinquency clears last. In the final three weeks before the sale, the treasurer typically demands cash or certified funds. Once the sale occurs, there is no redemption period: the buyer takes the property and the former owner’s interest is extinguished.
