Utah County, home to Provo and 700k Utahns, operates under Utah\'s distinctive property tax system. Owner-occupied primary residences receive a 45% Primary Residential Exclusion (Utah Constitution Art. XIII §3, statute 59-2-103) — meaning only 55% of fair market value is taxable. Non-primary residential (second homes, rentals not occupied 183+ days by single tenant) is taxed on 100% of FMV. Tax = (FMV × 55%) × Tax Rate. Utah\'s "Truth in Taxation" system (UCA 59-2-919) auto-adjusts rates downward when assessed values rise, so total revenue stays constant unless taxing entities vote for an increase (with public hearings required).
How the bill is built
Utah property tax follows a 4-step calculation. Step 1: Fair Market Value. The Utah County Utah Assessor's Office determines FMV annually using sales comparables and cost approaches. Step 2: Apply the 45% Primary Residential Exclusion (if owner-occupied primary). Taxable Value = FMV × 55%. Most homes carry the exemption forward from prior owner if used as primary residence. Step 3: Apply tax rate. Tax = Taxable Value × rate / $100. Utah County\'s combined consolidated rate is ~$1.00/$100 of FMV (≈$0.55% on taxable value, =~0.55% effective rate against full FMV). Step 4: Truth-in-Taxation. If the taxing entity\'s revenue would grow due to property value increases, rates auto-adjust downward — only if the entity wants MORE revenue does it hold a Truth-in-Taxation hearing.

Deductions and exemptions for 2026
Utah homeowner property tax relief is concentrated in three mechanisms: (1) the constitutional 45% Primary Residential Exclusion (Art. XIII §3, statute 59-2-103) — applied automatically to most homes, (2) the Truth-in-Taxation revenue-cap system (UCA 59-2-919) that auto-adjusts rates downward when values rise, and (3) the income-tested Property Tax Abatement / Circuit Breaker for low-income seniors 66+. Utah\'s disabled-veteran exemption is tiered (effectively full for sub-$544K homes, partial for higher-value homes).
45% Primary Residential Exclusion (constitutional, automatic for most)
Utah\'s primary owner-occupant protection is constitutional (Art. XIII §3) — taxable value = 55% of FMV for owner-occupied primary residences. Most Utah homes get the exemption automatically; it carries forward when a primary-residence home is sold to a new owner. Some counties require Form PT-19A application after ownership change. The exclusion applies to the home + up to 1 acre of land. A primary residence requires 183+ consecutive days of occupancy per year (by owner, family, or single tenant).
Truth in Taxation (UCA 59-2-919)
Truth-in-Taxation is unique to Utah — when property values rise, tax rates automatically adjust downward so that taxing entities\' total revenue stays constant. Only if a taxing entity wants MORE revenue does it hold a public Truth-in-Taxation hearing. This indirect protection has been credited with keeping Utah\'s effective rates among the lowest in the United States despite substantial home-value appreciation since 2018.
Property Tax Abatement / Circuit Breaker (income-tested)
Utah\'s primary senior-specific protection is the Property Tax Abatement (also called the Circuit Breaker) — a refundable abatement up to $1,259/year (2025 limit, indexed) for seniors 66+ or widow/widowers with household income below ~$40,840 (2025). Some counties also offer Indigent Property Tax Abatement and Property Tax Deferral. Apply with County Clerk by September 1.
Disabled Veteran Exemption (tiered)
Utah\'s disabled-veteran exemption is tiered based on disability percentage. 100% disabled vets receive an exemption of the first ~$299,166 of taxable value (2025, indexed annually). Since taxable value = 55% of FMV, this means a 100% disabled vet on a home with FMV up to ~$544K pays $0 — effectively full exemption for most Utah primary residences. Higher-value homes (Summit/Park City, Salt Lake luxury) still owe tax on the excess.
Appealing your assessment
Utah property tax appeals follow a 3-tier process. Level 1: County Board of Equalization (CBOE). File written appeal by September 15 after receiving the Notice of Property Valuation (mailed by August 1 each year — Utah uses a calendar tax year). The CBOE holds informal hearings — present comparable sales or condition documentation. Level 2: Utah State Tax Commission. If denied, appeal to the State Tax Commission within 30 days. Level 3: District Court. Tax Commission decisions can be appealed on legal grounds. Most Utah appeals are resolved at Level 1.
