Property Tax in Utah: Rates, Exemptions, and What Homeowners Actually Pay
Utah’s property tax system is unusually favorable for homeowners, and the mechanics explain why. The state’s effective property tax rate of about 0.55% is roughly half the national average of 1.10%, making it one of the lowest in the country for owner-occupied homes. The secret is the 45% primary residence exemption — a constitutional provision that reduces the taxable value of your home to just 55% of its assessed fair market value. A home assessed at $505,000 (Utah’s median) has a taxable value of only $277,750 for property tax purposes. At a typical combined tax rate of 1.0% (county, city, school district, and special districts combined), the annual tax bill is about $2,778. That’s $2,772 less than a homeowner would pay on the same assessed value without the exemption. This system matters when you’re budgeting for a home purchase — property taxes affect your monthly payment and your long-term cost of ownership. Run the numbers through our property tax calculator to see the impact at different price points.
How Utah Assesses Property Values
Utah county assessors are required to assess all property at 100% of fair market value as of January 1 each year. “Fair market value” means the price a willing buyer would pay a willing seller in an arm’s-length transaction. Use our net proceeds calculator for detailed numbers. Assessors use three approaches — sales comparison (looking at recent comparable sales), cost approach (estimating rebuild cost minus depreciation), and income approach (for rental/commercial properties) — to arrive at the assessed value.
The key distinction: assessed value is not the same as taxable value. For primary residences, the taxable value is 55% of the assessed value thanks to the constitutional exemption. For commercial property, rental property, and second homes, the taxable value equals 100% of the assessed value. Use our rent affordability calculator for detailed numbers. This creates a significant tax advantage for owner-occupants over investors and commercial property owners.
| Property Type | Assessment Rate | Taxable Portion | Tax on $500K Value (at 1.0% levy) |
|---|---|---|---|
| Primary Residence | 100% of FMV | 55% | $2,750 |
| Second Home / Vacation | 100% of FMV | 100% | $5,000 |
| Rental Property | 100% of FMV | 100% | $5,000 |
| Commercial Property | 100% of FMV | 100% | $5,000 |
| Agricultural Land | Productive value (greenbelt) | 100% | Varies (much lower) |
The 45% Primary Residence Exemption
Utah’s primary residence exemption is embedded in the state constitution (Article XIII, Section 2), which means it can’t be removed by the legislature without a constitutional amendment approved by voters. This gives homeowners long-term certainty that the exemption will continue. To qualify, the property must be your primary residence — where you live most of the year. Second homes, rental properties, and vacation properties do not qualify. If you rent out a portion of your home (like a basement apartment), the exemption may be partially reduced based on the rental percentage of the property.
The exemption applies automatically when you purchase a home and file your property as your primary residence with the county assessor. New homeowners should verify that the exemption is applied on their first tax bill — errors occasionally occur, particularly on new construction where the property type may default to non-residential in the assessor’s system. If the exemption is missing, contact your county assessor’s office to apply it retroactively.
How Tax Rates Are Set
Utah uses a “truth in taxation” system that limits how much total property tax revenue a taxing entity can collect. When assessed values increase across a jurisdiction, the tax rate automatically decreases to keep total revenue neutral. If a city, school district, or county wants to increase its total property tax revenue beyond what market growth provides, it must hold a public “truth in taxation” hearing and formally vote to adopt a higher rate. This system means that rising home values don’t automatically mean higher tax bills — the rate adjusts downward to compensate. Your individual tax bill may still increase if your property’s value rose faster than the average in your taxing district.
Your total property tax rate is the sum of multiple overlapping taxing entities:
| Taxing Entity | Typical Rate Range | Purpose |
|---|---|---|
| County | 0.10-0.20% | County services, roads, public safety |
| City/Town | 0.15-0.35% | Municipal services, parks, police/fire |
| School District | 0.40-0.70% | K-12 education (largest single component) |
| Special Districts | 0.05-0.15% | Water, sewer, fire, mosquito abatement, etc. |
| Total Combined | 0.80-1.30% | Before primary residence exemption |
Effective Tax Rates by County
Because school districts and special district rates vary significantly, your effective tax rate depends heavily on where in Utah you live. These figures reflect the effective rate after the primary residence exemption for owner-occupied homes.
| County | Effective Rate (Owner-Occupied) | Annual Tax on $505K Home |
|---|---|---|
| Salt Lake County | 0.58% | $2,929 |
| Utah County | 0.48% | $2,424 |
| Davis County | 0.56% | $2,828 |
| Weber County | 0.62% | $3,131 |
| Washington County | 0.50% | $2,525 |
| Summit County | 0.45% | $2,273 |
| Cache County | 0.53% | $2,677 |
| Iron County | 0.55% | $2,778 |
Tax Relief Programs
Circuit Breaker Program
Utah offers a “circuit breaker” property tax credit for low-income homeowners, particularly seniors. The program provides a refundable tax credit that offsets part or all of the property tax burden for households with income below certain thresholds. For homeowners age 66 or older with household income below $38,369 (2025 threshold), the credit can reduce the effective property tax to near zero. The credit is claimed on the Utah state income tax return (TC-40, Schedule H). Renters who are 66+ may also qualify for a credit based on the property tax portion of their rent.
Veteran’s Exemption
Disabled veterans with a 10% or greater VA disability rating can receive a property tax exemption on a portion of their home’s taxable value. The exemption amount increases with disability percentage, reaching full exemption of the first $299,166 of taxable value (2025 figure, adjusted annually) for veterans with 100% disability rating. Surviving spouses of qualifying veterans may also be eligible. Application is through the county assessor’s office with VA documentation.
Blind Exemption
Legally blind property owners receive a property tax exemption similar to the veteran’s exemption structure. Application requires documentation from an ophthalmologist and is filed with the county assessor.
How Utah Compares to Other States
Utah’s property tax burden looks especially favorable when compared to neighboring and competitor states. The 45% primary residence exemption is a structural advantage that most other states lack, though some achieve similar effective rates through different mechanisms.
| State | Effective Rate (Owner-Occupied) | Tax on $505K Home | Homestead Exemption |
|---|---|---|---|
| Utah | 0.55% | $2,778 | 45% of assessed value |
| Colorado | 0.51% | $2,576 | Assessment ratio (6.7%) |
| Idaho | 0.63% | $3,182 | $125,000 exemption |
| Arizona | 0.62% | $3,131 | Limited (assessment ratio) |
| Nevada | 0.53% | $2,677 | Tax cap (3% annual increase) |
| Texas | 1.68% | $8,484 | $100,000 homestead |
| New Jersey | 2.23% | $11,262 | Limited |
| National Average | 1.10% | $5,555 | Varies |
For buyers relocating from high-property-tax states like Texas, New Jersey, or Illinois, Utah’s effective rate can save $3,000-$8,000 annually on the same-value home. That savings is partially offset by Utah’s 4.65% income tax (Texas and Nevada have none), but for most households the net tax burden is favorable in Utah. Retirees comparing Sun Belt options should factor property taxes heavily — the difference between Utah’s 0.55% and Texas’s 1.68% on a $500K home is $5,700 per year, which accumulates to $57,000 over a decade. Our affordability calculator helps model how property taxes affect purchasing power across different markets.
Special Situations
New Construction
Newly built homes may show a lower assessed value during the first year because the assessment reflects the property’s condition as of January 1 of the tax year. If your home was under construction on January 1, the assessment may reflect the land value plus partial construction. The following year’s assessment will reflect the completed home’s full market value, which often means a significant property tax increase in year two. Budget for this increase when purchasing new construction — it’s one of the most common surprises for first-time buyers.
Homes With Accessory Dwelling Units
If you build an ADU (accessory dwelling unit, or “mother-in-law apartment”) and rent it out, the assessor may reclassify the rental portion of your property as non-residential, losing the 45% exemption on that square footage. The exemption applies only to the portion of the property used as your primary residence. A basement apartment rented to tenants could trigger partial reclassification. Consult your county assessor before adding a rental unit to understand the tax implications.

Frequently Asked Questions
Why are Utah property taxes so low?
The primary reason is the 45% constitutional exemption for owner-occupied homes, which reduces the taxable value to just 55% of fair market value. Combined with the truth-in-taxation revenue cap system, which prevents taxing entities from automatically collecting more when values rise, the result is an effective rate about half the national average. Utah compensates with a flat 4.65% income tax and a sales tax averaging 7.19%, so the overall tax burden is moderate rather than truly low. Our mortgage calculator factors property taxes into the monthly payment estimate.
Do property taxes go up every year in Utah?
Not necessarily. Under the truth-in-taxation system, tax rates automatically adjust downward when assessed values increase, keeping total revenue to each taxing entity constant unless they vote for a specific increase. Your individual bill may increase if your property’s value rose faster than the district average, but the rate itself drops to offset aggregate value gains. Taxing entities that want to collect more revenue must hold public hearings and formally adopt higher rates — this process is designed to create transparency and accountability. Use our property tax calculator to estimate your annual burden at current rates.
How does the primary residence exemption affect real estate investors?
Investors pay significantly more in property tax than owner-occupants on the same-value property. An investor owning a $505K rental property pays tax on 100% of the assessed value, while an owner-occupant pays on only 55%. On the same property, that’s roughly $5,050 in annual taxes for the investor versus $2,778 for the homeowner. This tax differential is an important factor for investors calculating cash flow and ROI on Utah rental properties. Our rent vs. buy calculator models these ownership cost differences.
What happens if I don’t pay my property taxes?
Utah imposes a 1% per month penalty on late property tax payments starting December 1 (the day after the November 30 deadline). After the January 1 delinquency date, the county may initiate a tax lien process. If taxes remain unpaid for five years, the county can conduct a tax sale of the property. In practice, most delinquent homeowners resolve their tax debt before it reaches the sale stage, often through payment plans offered by the county treasurer’s office.
Can I pay my property taxes in installments?
Utah does not have a statewide installment payment program — the full amount is due November 30. However, mortgage lenders typically collect property taxes monthly as part of your escrow payment and pay the full amount on your behalf by the deadline. If you don’t have an escrow account (common with homes owned free and clear or with some credit union mortgages), you’ll receive the full bill in November and must pay the lump sum by the deadline. Some counties offer hardship payment plans for qualifying homeowners — contact your county treasurer’s office for options.
