The Wasatch County property tax rate for 2025 falls between roughly 0.008533 and 0.010894 per dollar of taxable value in most residential tax areas, which works out to about $8.53 to $10.89 per $1,000. A few tax areas sit higher because of extra special-district levies. Because Utah taxes a primary residence on only 55% of its fair market value, the real bite on an owner-occupied home is noticeably smaller than the raw rate suggests.
On a home with a $600,000 market value that qualifies as a primary residence, taxable value is $330,000. At 0.008533 the annual bill is about $2,816; at 0.010894 it’s about $3,595.
Why There Isn’t a Single Countywide Rate
Wasatch County had more than 40 distinct tax areas for the 2025 tax year, and the Utah State Tax Commission publishes final adopted rates for each one. Your rate is the sum of every taxing entity that overlaps your parcel: the county, your city or town (or none, if you’re in unincorporated land), the school district, and any special service districts for things like water or fire. A home inside Heber City carries a different mix than one near Midway or along the Jordanelle corridor.
The cleanest way to find your exact rate is your annual valuation notice, which lists every entity and its individual levy. You can also look up the parcel through the Wasatch County Treasurer’s online search tool.
What the Rate Is Applied To
The Wasatch County Assessor appraises every parcel each year at fair market value, meaning what it would sell for under normal conditions. That number is not always what the tax is calculated on.
The 45% Residential Exemption
Utah law reduces the taxable value of a primary residence to 55% of fair market value. A home appraised at $500,000 is taxed on $275,000. Second homes, vacation properties, and commercial real estate do not qualify and are taxed on 100% of market value, which matters in a county with a large vacation-home market.
You have to claim the exemption by filing a primary-residence declaration with the Wasatch County Assessor’s office. If you bought or moved in midyear, file the form before June so you don’t have to raise the issue at the Board of Equalization later.
Agricultural Land
Qualifying farmland can be taxed on productive agricultural value instead of market value under Utah’s Farmland Assessment Act, often called the Greenbelt Act. In a county where land values have climbed sharply, the difference can be substantial. Land generally must be at least five contiguous acres, actively devoted to agriculture at production levels of at least 50% of the county average for that land type, and in agricultural use for the two consecutive years before the tax year. If greenbelt land is later converted or becomes ineligible, the county imposes a rollback tax covering up to five preceding years, equal to the gap between what was paid and what full market value would have produced.
Why Your Rate Can Change Even When Values Rise
Each year the state calculates a “certified tax rate” for every taxing entity. That rate is set to generate roughly the same revenue the entity collected the prior year, adjusted for new growth. When countywide values rise, the certified rate drops, so an entity doesn’t automatically collect a windfall from appreciation alone.
An entity that wants more revenue than the certified rate provides has to go through Utah’s Truth-in-Taxation process: publicly announce the proposed increase, mail direct notice to affected property owners, and hold an evening public hearing (starting at or after 6 p.m., with no other agenda items). This applies to the county, your city, the school district, and every special service district on the bill. If none of them exceed their certified rate in a given year, your total rate can fall even as your market value climbs.
If the Assessed Value Looks Too High
You can challenge the assessor’s fair market value in front of the Wasatch County Board of Equalization. The appeal has to be received, whether online, in person, or by mail, by September 15 at 5 p.m., or within 45 days of the date on your valuation notice, whichever gives you more time. Every appeal must include supporting evidence for each parcel; filing without evidence means denial.
The strongest evidence is recent sales of comparable properties in your area, meaning homes of similar size, age, and condition that sold for less than your assessed value. A professional appraisal helps but isn’t required. Photos of problems the assessor couldn’t see from a desk, like deferred maintenance, drainage issues, or exposure to a busy road, can also matter. The board can lower, confirm, or raise your value, so make sure your evidence actually supports a lower number before you file.
Paper forms are available at the Clerk/Auditor’s Office at 25 North Main Street in Heber City, and 435-657-3190 reaches staff who can help.
Programs That Can Reduce What You Owe
Separate from the rate, Utah runs several relief programs that cut or defer the bill for qualifying homeowners. All are applied for through Wasatch County and none are automatic. The deadline is September 1.
Veterans with a service-connected disability of at least 10% can exempt up to $521,620 of taxable value, scaled to the disability percentage, and the exemption extends to an unmarried surviving spouse or minor orphans. Legally blind homeowners can exempt up to $11,500 of taxable value with no income or age test. Utah’s circuit-breaker credit is income-based for homeowners who meet residency and income limits; current thresholds are updated annually by the Utah State Tax Commission in Publication 36, and you should confirm the figures when applying. Homeowners aged 75 or older who meet income and asset limits may defer property taxes entirely, with payment postponed until the home is sold or the owner dies; mortgage lender approval is required.
Deadlines and Late Penalties
The yearly calendar runs on a predictable rhythm:
- Late July: valuation notices mailed, showing assessed market value and projected tax.
- September 1: deadline for relief applications (circuit breaker, veteran, blind).
- September 15: deadline to appeal to the Board of Equalization.
- November 30: annual property taxes are due. This is the hard deadline.
Pay a single day late and penalties start. If you clear the full balance, penalty included, by January 31, the penalty is 1% of the delinquent amount or $10, whichever is greater. Miss that window and the penalty rises to 2.5% of the outstanding balance or $10, whichever is greater, plus interest that accrues retroactively from January 1 at the Federal Funds Rate. Taxes that remain unpaid for four full years put the property at risk of a tax sale the following May or June, with redemption rights ending once the sale happens.
Payment options include the county’s online portal (an electronic payment processing fee applies), a mailed check or money order to the Treasurer’s Office, or in person at the county administrative building in Heber City. If a mortgage lender handles escrow, the obligation still belongs to you: verify after November 30 that the county shows the taxes as paid.
