The property tax rate in Lehi, Utah isn’t a single number. Your bill is built from separate levies charged by Lehi City, Utah County, the Alpine School District, and a handful of smaller special service districts whose boundaries overlap your parcel. Combined rates in Lehi tend to land near 0.0095 (just under 1% of taxable value), but the exact figure depends on which tax area your home sits in. After Utah’s 45% primary-residence exemption, you only pay tax on 55% of your home’s market value, which keeps the effective burden well below what the headline rate suggests. The authoritative lookup is the Utah County Treasurer’s rate search at treasurer.utahcounty.gov.1Utah County Government. Tax Rates Search
Why There’s No Single Lehi Rate
Every taxing entity authorized to levy against your parcel adds its own piece to the combined rate. For most Lehi homes, the Alpine School District is the largest single share, followed by Lehi City and Utah County, with smaller amounts going to special service districts covering things like water infrastructure and cemetery maintenance.
Lehi contains multiple tax areas (district codes), and the combined rate shifts slightly from one area to the next depending on which special districts apply. Rates are certified each fall. To find the exact rate on your home, pull up your district code from your annual valuation notice and look it up on the County Treasurer’s rate table, or check the rate printed on the notice itself.
The 45% Residential Exemption Does the Heavy Lifting
Utah’s constitution reduces the taxable value of an owner-occupied primary residence by 45%, so property tax applies to only 55% of the home’s fair market value.2Utah State Tax Commission. Primary Residential Exemption On a Lehi home valued at $585,000, taxable value drops to roughly $321,750. This exemption is the single biggest reason effective tax rates in Lehi stay low relative to the nominal combined rate.
The exemption applies automatically to most owner-occupied homes. It does not apply to vacation properties, second homes, or units placed in a rental pool — those are taxed on 100% of fair market value.3Utah County Government. Residential Exemption If your home stops qualifying as a primary residence (you move out and start renting it, for example), Utah law requires you to file a written statement with the county board of equalization and declare the change on your state income tax return for that year.4Utah Legislature. Utah Code 59-2-103.5 – Residential Property Declaration Not reporting the change can result in back taxes plus penalties.
Calculating What You’ll Actually Owe
Three numbers get you an estimate: your home’s fair market value, the 0.55 exemption multiplier, and the combined rate for your tax area. Multiply the first two to get taxable value, then multiply taxable value by the combined rate.
For a Lehi home with a fair market value of $585,000:
- Taxable value: $585,000 × 0.55 = $321,750
- Annual tax at a combined rate of 0.0095: $321,750 × 0.0095 = $3,057
The 0.0095 figure is illustrative. Plug in the actual rate for your district code to get a close estimate. If the home isn’t your primary residence, skip the 0.55 step and apply the rate to the full market value, which nearly doubles the result.3Utah County Government. Residential Exemption
How Lehi Homes Are Valued
The Utah County Assessor sets the fair market value of every taxable property as of January 1 each year, using mass appraisal methods built on comparable sales, market trends, and property characteristics like square footage, lot size, age, and condition.5Utah Legislature. Utah Code 59-2-103 – Rate of Assessment of Property – Residential Property The county also updates records whenever permits are pulled for additions, remodels, or other improvements. Lehi’s growth as a technology corridor has pushed values up substantially; the median home price reached about $585,500 in early 2026.
Rising values don’t automatically produce a dollar-for-dollar increase in your tax bill. Each taxing entity receives a “certified tax rate” from the county that is calculated to generate roughly the same revenue as the prior year, adjusted for new growth, so the certified rate tends to float downward as values climb.6Utah Legislature. Utah Code 59-2-919 – Notice and Public Hearing Requirements for Certain Tax Increases An entity that wants to collect more than the certified rate must go through Utah’s Truth in Taxation process, including mailed parcel-specific notices and a public hearing.7Utah State Tax Commission. Tax Increase Requirements
Appealing a Value You Think Is Too High
Valuation notices arrive in the summer. If the assessed value exceeds what your home would actually sell for, file an appeal with the Utah County Board of Equalization. The deadline is September 15 (or the next business day if that falls on a weekend or holiday), or within 45 days of the notice mailing date if that gives you more time.8Utah State Tax Commission. Appeals of Locally Assessed Property
You need evidence. A recent independent appraisal, comparable sales showing your home is overvalued relative to similar properties, or documentation of physical defects the county’s records don’t reflect all work. Submit evidence to both the commission and the county at least ten business days before the hearing or the board may refuse to consider it.
Late appeals filed after September 15 but before March 31 of the following year are accepted only in narrow circumstances: a medical emergency, a death in the family, a county notification failure, or a factual error in the records. The reliable path is filing by September 15.
When the Bill Is Due and What Late Costs
Utah County property taxes are due November 30 each year. A U.S. Post Office postmark counts for mailed payments; a private office postage meter stamp does not.9Utah County Government. Tax Information You can pay online by electronic check (no fee), by card (2.65%, or a flat $3.95 for Visa debit), in person at the Treasurer’s office in Provo, or by mailed check.10Utah County Government. Pay Taxes Online
Miss the deadline and the penalty structure escalates. Pay all delinquent taxes by January 31 and the penalty is 1% of the overdue amount (or $10, whichever is greater). After January 31, the penalty rises to 2.5% (or $10, whichever is greater), and interest begins accruing retroactively from the January 1 following the delinquency date.11Utah Legislature. Utah Code 59-2-1331 – Delinquent Property Tax and Tax Notice Charges The interest rate equals 6% plus the federal funds rate target, with a floor of 7% and a ceiling of 10%. On a $3,000 bill, even the minimum 7% rate adds roughly $210 per year on top of the penalty.
Taxes unpaid for four years from the original deadline put the property on the county’s May tax sale auction. Delinquent owners can redeem the property before the sale only by paying all outstanding taxes, interest, penalties, and administrative costs in full. Partial payments won’t stop the process.
Programs That Can Lower the Bill Further
Utah administers several relief programs through the county, and most share a September 1 application deadline.12Utah State Tax Commission. Publication 36 – Property Tax Abatement, Deferral and Exemption Programs
Circuit Breaker Credit
For older homeowners with limited income. You must be at least 66 (if born on or before December 31, 1959) or 67 (if born on or after January 1, 1960), and your total household income for the prior year must fall below the state’s threshold — $44,221 for the 2026 tax year. Unmarried surviving spouses of qualifying individuals can claim the credit regardless of their own age.13Utah Legislature. Utah Code 59-2-1202 – Definitions
Disabled Veterans Exemption
Veterans with a service-connected disability rating of 10% or higher can exempt a portion of taxable value, up to $521,620 at a 100% rating. The exemption scales with the rating, so a 50% rating gets 50% of the maximum. Surviving spouses and minor orphans of service members killed in action or who died in the line of duty can exempt the entire value of the primary residence.14MyArmyBenefits. Utah Military and Veteran Benefits First-time applicants file documentation of service and VA disability percentage with the county auditor or treasurer.
Blind Exemption
Legally blind residents (corrected visual acuity of 20/200 or less in the stronger eye, or a visual field of 20 degrees or less) can exempt up to $11,500 of assessed value. First-time applicants need an ophthalmologist’s verification.15Salt Lake County. Blind Relief
Indigent Abatement
Homeowners facing extreme financial hardship can apply for an abatement of up to 50% of the current year’s property tax, capped at $1,412. You must occupy the home for at least 10 months of the year, have household income below $44,221, and either meet the age requirement (67+), demonstrate a disability, or show extreme hardship. The county legislative body decides.
If You Have a Mortgage, Your Servicer Pays It
Most Lehi homeowners with a mortgage don’t send a check to the county. The loan servicer collects a monthly escrow amount bundled into the mortgage payment and pays the tax bill on the borrower’s behalf. Federal regulations require the servicer to run an annual escrow analysis and send a statement within 30 days of the end of the escrow computation year.16Consumer Financial Protection Bureau. Regulation 1024.17 – Escrow Accounts
When Lehi values rise, your assessed value goes up, the tax bill follows, and the servicer adjusts the escrow portion of your monthly payment. That escrow adjustment is often the first place homeowners notice a tax increase. If the analysis shows a surplus, the servicer refunds it; a shortage pushes the monthly payment up, sometimes spread over 12 months. Read the annual escrow statement carefully. Servicer errors happen, and catching a miscalculation early saves months of overpayment.
