How Assessment Works in Utah
Utah assesses all property at 100% of fair market value. However, primary residential property receives a 45% exemption, so the effective taxable rate is 55% of market value. Your assessed value should reflect current market value.
Risk of Increase
In Utah, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ
Utah Property Tax Appeal Questions
How does the 45% primary residential exemption work?
If your primary home has a fair market value of $400,000, the full assessed value is $400,000 but the taxable value is $220,000 (55% after the 45% exemption). Your tax bill is based on the $220,000 taxable value.
Can my Utah assessment increase on appeal?
Yes. The Board of Equalization can increase your assessment. However, this is uncommon when you present strong evidence of over-assessment.
How often are Utah properties reassessed?
Utah requires annual reassessment of all property. The county assessor determines fair market value as of January 1 each year.
What is the effective property tax rate in Utah?
Utah property tax rates vary by county, municipality, and school district, but the effective rate (annual tax paid divided by market value) typically ranges from about 0.5% to 2.5%. Because Utah assesses property at 100% (55% residential primary) of market value, your actual tax bill depends on both the assessed value and the local millage or mill levy applied on top of it. If your assessed value is higher than comparable sales support, filing a appeal is one of the only ways to reduce your effective rate without waiting for a reassessment.
How long does a property tax appeal take in Utah?
Most Utah appeals take between 6 weeks and 6 months from filing to final decision. After you file Board of Equalization appeal form, the assessor or review board schedules a hearing — typically within 30 to 90 days — and issues a written decision shortly after. Cases that settle informally resolve faster, while cases that advance to a formal hearing or court appeal can take several additional months. ProtestMax prepares your full evidence packet in minutes so you can file immediately and start the clock.
Can I appeal my property taxes every year in Utah?
Yes. In Utah, homeowners generally have the right to appeal their property tax assessment every year, as long as you file by the September 15, 2026 deadline. Even if you won a reduction last year, your assessor can revalue your property the following year, and you retain the right to challenge the new value. Annual appeals are especially important during years when market values are flat or falling but assessments keep rising.
What evidence is most persuasive in Utah hearings?
The strongest evidence in a Utah appeal hearing is recent comparable sales — homes similar to yours in size, age, condition, and location that sold for less than your assessed value within the last 6 to 12 months. Equity comparisons (similar homes assessed for less than yours) are also highly persuasive. Photos of deferred maintenance, structural issues, or negative location factors (busy roads, flood zones, power lines) strengthen your case further. ProtestMax assembles all of this evidence into a hearing-ready packet tailored to Utah's rules.
