Utah Property Taxes Explained: Rates, the 45% Exemption, and What You Will Actually Pay

Property taxes are one of the pleasant surprises for people moving to Utah, and one of the most misunderstood line items for people who already live here. The rates are low, the system is unusual, and the two things that catch buyers off guard, the 45% exemption and the new-construction jump, are easy to plan for once you understand them.

This guide explains how the system works, what you should expect to pay in Utah County, Salt Lake County, and Summit County, and how to appeal if your assessment is wrong. Figures are 2026 estimates; confirm against your county assessor's site and your own tax notice.

How Utah calculates your bill

The math has three parts:

1. Market value. The county assessor estimates what your home would have sold for on January 1 of the tax year. They do this with mass-appraisal models, not a walk-through.
2. Taxable value. If the home is your primary residence, Utah taxes 55% of market value. That 45% primary residential exemption is the single biggest reason Utah bills are low. It covers the home and up to one acre.
3. Rate. Every property sits inside a county, a city or township, a school district, and usually a handful of special districts for water, mosquito abatement, libraries, and so on. Each sets its own rate, and your bill is the sum.

Put together, a $600,000 primary residence with a combined rate of 1.0% on taxable value pays $600,000 × 55% × 1.0% = $3,300 per year. Expressed against the full market value, that is an effective rate of 0.55%.

Effective rates by county

Combined rates vary by city and school district inside each county, but here is where primary residences along the Wasatch Front usually land. Rates are approximate; look up the exact tax area on the county assessor's parcel page before you rely on them.

County	Typical effective rate (primary residence)	Annual tax on $600,000	What drives the spread
Utah County	0.45% – 0.6%	$2,700 – $3,600	Alpine School District split cities vs. Provo and Nebo; some cities have no municipal property tax
Salt Lake County	0.5% – 0.7%	$3,000 – $4,200	Salt Lake City and Granite-district cities tend higher; Sandy, Draper, and Riverton tend lower
Summit County (Park City)	0.35% – 0.55%	$2,100 – $3,300	Low rates, but most Park City buyers lose the exemption on second homes

Two practical takeaways. First, the difference between a low-tax and a high-tax city on the same purchase price is usually $600 to $1,200 a year, real money but rarely the thing that should decide where you buy. Second, Summit County's low rate only helps if the property is your primary residence.

The second-home trap

If you are buying a Park City condo you will use on weekends, a Daybreak townhome you plan to rent, or any property you will not live in, you do not get the 45% exemption. The property is taxed on 100% of market value, so the bill is roughly 1.8 times what the current owner paid if they lived there.

The county does not know your intent. When you buy, you will receive or need to file a residential property declaration confirming the home is your primary residence. If you later move out and rent it, you are supposed to tell the assessor. Buyers who inherit an exemption they do not qualify for sometimes get a back-tax bill when the county catches up. Budget for the full-value number from the start on any second home or rental.

Key dates in the Utah property tax year

Date	What happens
January 1	Valuation date; the assessor values your home as of this day
Late July	Notice of Valuation and Tax Changes mailed
August	Truth in Taxation hearings if any entity proposes a rate increase
September 15	Appeal deadline to the County Board of Equalization, or 45 days after the notice if later
October / November	Tax bills mailed
November 30	Taxes due for the current calendar year
December 1	Penalty applies to unpaid balances

How property taxes work at closing

Utah collects taxes in arrears, which affects two things at closing.

Proration. The seller owes taxes from January 1 through closing day; the buyer owes the rest. Because the bill is not due until November 30, the seller usually gives the buyer a credit on the settlement statement for the seller's share, and the buyer then pays the whole bill in November. Close on July 1 on a home with a $3,600 annual bill, and you receive roughly $1,800 from the seller at closing.

Escrow. If your lender escrows taxes, they collect one-twelfth of the estimated annual bill in each monthly payment and need enough in the account to pay the November bill. Close in September and your initial escrow deposit will be large; close in December, right after the bill was paid, and it will be small. This is the reason buyer prepaids swing so widely in my closing costs guide.

The new-construction jump

This one catches more buyers than anything else on this page.

When you close on a newly built home, the current year's tax bill is based on what existed on January 1. If the lot was dirt in January, the bill is for the lot. Your lender sets up your escrow account using that tiny bill. The following January the assessor values the finished house, the bill goes up by several thousand dollars, and your lender discovers the escrow account is short. Your monthly payment then rises to cover both the new higher bill and the shortage from the prior year.

A $650,000 new build in Lehi or Herriman can see the monthly payment rise by $300 to $450 in year two. It is not a mistake and it is not a rate increase. It is just the real bill arriving. I tell every new-construction client to set aside the difference from day one so the adjustment is a non-event.

How to appeal your assessment

Assessors value tens of thousands of homes with models, so individual misses are common, especially right after a market shift. If your Notice of Valuation says more than your home would have sold for on January 1:

1. Check the facts first. Wrong square footage, wrong bed and bath count, a finished basement that is not finished. Factual errors are the easiest wins and the assessor can often fix them without a formal appeal.
2. Pull comparable sales near January 1. Three to five closed sales of similar homes from roughly October through March. I pull these from the MLS for clients at no charge; it takes me fifteen minutes.
3. File with the County Board of Equalization by September 15. Each county has an online form. Attach your comps, photos of condition issues, and any appraisal from the last year.
4. Expect a decision in the fall. Many appeals settle at a reduced value without a hearing.

A $40,000 reduction in market value on a primary residence saves about $220 a year at typical rates. Worth doing when the gap is real; not worth a fight over a few thousand dollars.

Relief programs worth knowing

• Circuit Breaker. Utah's abatement for lower-income homeowners age 66 and older, and surviving spouses of any age, can cut the bill substantially. Income limits are modest and change yearly; check with your county treasurer.
• Veterans with a disability. A service-connected disability rating of 10% or more earns an exemption on a portion of taxable value, scaled with the rating. Active-duty service members deployed out of state may qualify for a separate exemption.
• Blind exemption and indigent abatement. Smaller programs administered by the county.
• Deferral. Some homeowners over 75 can defer taxes until the home is sold.

All of these are applied for through the county, not the state, and most have a September 1 deadline.

Relocating from a high-tax state?

For most of my clients from Texas, Illinois, New Jersey, or the Northeast, the property tax bill on a comparable Utah home is one-third to one-half of what they were paying. Pair that with a flat state income tax around 4.5% and the overall picture is favorable. The relocating to Utah guide covers the full tax and cost-of-living comparison.
