Utah Property Tax Calculator

Quick answer

Utah taxes a primary residence on just 55 percent of its market value, because of the 45 percent residential exemption. That is the single reason Utah’s effective property tax rates look so low compared to the rest of the country, averaging roughly 0.5 percent of market value statewide against a national average near 1 percent. A second home, short term rental, or investment property gets no exemption, is taxed on 100 percent of value, and runs roughly 80 percent more in tax on the identical house.

How to use this calculator

Enter the home’s market value, pick the county, and set whether it is a primary residence or a second home or rental. The result shows the estimated annual bill, the taxable value after the exemption, and the monthly equivalent, which is the figure your lender folds into escrow.

The county rates here are averages. Use them to plan, not to budget to the dollar. For the full comparison of every county side by side, see the deep reference: Utah property tax rates for all 29 counties.

The 45 percent primary residence exemption

If a Utah property is your primary residence, 45 percent of its market value is exempt from property tax. You are taxed on the remaining 55 percent, called the taxable value. Long term rentals occupied as a tenant’s primary residence generally qualify as well.

This is why nominal and effective rates diverge so much in Utah. A tax area with a nominal rate near 1.1 percent produces an effective rate near 0.6 percent on an owner occupied home, because nearly half the value never gets taxed.

One practical note: counties may require a signed residential exemption declaration after a purchase, particularly when the prior owner did not claim it or the property was previously a second home. Check with your county assessor after closing, because the exemption is not always automatic.

Second homes, rentals, and short term rentals

No exemption applies. These are taxed on 100 percent of market value, so the same house carries roughly 80 percent more property tax than it would as a primary residence. In practical terms, an effective rate near 0.55 percent becomes closer to 1.0 percent.

If you are modeling a cabin in Midway, a condo in Park City, or a short term rental in Washington County, run the number both ways in the calculator above. The difference is often several thousand dollars a year and is one of the most commonly missed line items in second home budgets.

How the certified tax rate works

Utah uses a certified tax rate system, commonly called Truth in Taxation. Each year, every taxing entity’s rate is recalculated so it collects the same revenue as the prior year, plus revenue from new construction.

The consequence is counterintuitive if you are used to other states: when property values rise across a district, rates automatically float down. Your bill does not climb just because your assessed value did, unless your value rose faster than your neighbors’ or your taxing entities voted for an increase. Any entity that wants more than the certified rate delivers has to advertise the proposed increase and hold public hearings first.

Rates therefore change at least slightly every year in every taxing district, which is why any calculator, including this one, is an estimate.

Rates vary by district inside a county

Your bill is not set by the county alone. It is the sum of levies from the county, your city, your school district (usually the largest single slice), and any special service districts covering your parcel for water, sewer, fire, or mosquito abatement.

Those levies stack into one combined rate for your specific tax area. Salt Lake County alone contains more than 400 distinct tax areas, which is how two similar homes a mile apart end up with different rates. Treat the county average as a planning figure and confirm your parcel’s actual rate with the county treasurer.

Greenbelt and agricultural assessment

Utah’s Farmland Assessment Act, usually called greenbelt, assesses land actively used for agriculture on its agricultural productivity value rather than market value. Qualifying generally requires at least five contiguous acres meeting production standards, with narrower exceptions.

The savings can be dramatic while the land stays in agricultural use. The catch is the rollback tax: when the land converts to development or another non agricultural use, several prior years’ worth of the tax difference becomes due, typically payable by the party triggering the conversion. If you are buying Utah acreage, ask early whether it is in greenbelt and who is responsible for rollback at closing.

When notices arrive and when the bill is due

• Valuation notice, generally mailed in July, tells you the assessor’s opinion of value and starts your appeal window.
• Tax notice, generally mailed in October, is the actual bill.
• Payment is due November 30. Late payments accrue penalty plus interest.
• If you escrow, your lender pays it for you. Verify that it was actually paid the first year after a purchase or refinance, since escrow setup is where errors show up.

How to appeal your valuation

If the assessed value looks high, appeal it to your county’s Board of Equalization. The deadline is generally September 15, or 45 days after your valuation notice is mailed, whichever is later, but confirm your county’s exact date because it can shift year to year.

What actually wins appeals:

1. Comparable sales near the January 1 assessment date, not today’s listings. The assessment reflects a specific date.
2. Documented condition issues, with photos and contractor estimates, that a mass appraisal model would not see.
3. A recent arm’s length purchase price below the assessed value, which is usually the strongest evidence available.

Successful appeals commonly reduce assessments somewhere in the 5 to 25 percent range. Most over assessed Utah homeowners never file, which is the main reason the opportunity persists. If you need comparable sales to support an appeal, call and we will pull them.

An estimate, not a bill

Every figure here is a planning estimate built on county average rates. It is not a tax bill, a title report, or an appraisal. Actual amounts vary by city, school district, special service districts, and any voter approved bonds, and rates are reset annually. Always confirm with your county treasurer before relying on a number.
