Utah Mortgage Calculator
Utah’s constitution exempts 45% of a primary residence’s value from property tax, so owner-occupied homes are taxed on just 55% of market value, while second homes and investment property are taxed on the full amount. This Utah mortgage calculator with taxes and insurance lets you toggle that difference directly, alongside real county tax rates from Salt Lake City to St. George.

Why Utah’s 45% Primary Residential Exemption Matters
Utah is one of the most homeowner-friendly states in the country for property tax, and it comes down to one constitutional rule: a primary residence, plus up to one acre of land, is exempt from property tax on 45% of its fair market value. You’re only taxed on the remaining 55%. Second homes, short-term rentals, and investment property don’t qualify and are taxed on the full 100%, which is a huge swing on an identical house. A generic utah mortgage calculator that skips this will meaningfully overstate what an owner-occupant actually pays. Toggle “Primary residence” versus “Second home / investment” above and watch the tax estimate move.
Utah Property Tax by County: The Real Spread
| County | Effective rate (primary residence) | Notes |
|---|---|---|
| Rich | 0.26% | Lowest in the state, near Bear Lake |
| Summit (Park City) | 0.35% | Low rate despite high resort-area home values |
| Grand (Moab) | 0.41% | Below statewide average |
| Washington (St. George) | 0.42% | Below statewide average |
| Utah County (Provo) | 0.44% | Fast-growing tech corridor |
| Salt Lake County | 0.54% | Most populous county, close to average |
| Weber County (Ogden) | 0.60% | Above statewide average |
| San Juan | 0.80% | Highest documented rate in the state |
Utah’s Circuit Breaker Homeowner’s Credit
Separate from the 45% exemption, Utah offers the Circuit Breaker, officially the Homeowner’s Tax Credit, for qualifying homeowners age 66 or 67 (the exact age depends on your birth year) with household income under roughly $44,000 for the current program year. Depending on income, it can abate over $1,400 of property tax, plus an additional credit equal to the tax on 20% of your home’s fair market value. Unmarried surviving spouses can qualify regardless of age. You must reapply every year with your county by September 1, and the income threshold adjusts annually, so confirm the current figures with your county treasurer.
Utah Has No Real Estate Transfer Tax
Unlike many states, Utah charges no state or local real estate transfer tax when a property changes hands. The only government-related charge at closing is a modest county recording fee, typically well under $50. Combined with a title-company-based closing process rather than a mandatory attorney requirement, this keeps Utah’s overall closing costs among the lowest in the country, generally in the 1% to 2.5% range before real estate commissions.
How Much House Can You Afford in Utah?
The affordability badge above uses the standard 28% front-end ratio most conventional lenders reference. Because Utah’s effective property tax on a primary residence already runs well below the national average, a Utah buyer often qualifies for more house than the same income would support in a higher-tax state, even before accounting for the fact that Utah also has no transfer tax eating into your closing costs.
Fast-Growing Markets and Reassessment
Wasatch Front counties, along with Summit, Wasatch, and Washington Counties, have seen some of the fastest home price growth in the country over the past several years. Utah county assessors reassess market value annually, so a rapidly appreciating home can see its assessed value, and therefore its tax bill, rise meaningfully year over year even without a rate change, especially in Salt Lake, Utah, and Washington Counties.
Frequently Asked Questions
What is Utah’s 45% primary residential exemption?
A constitutional exemption that removes 45% of a primary residence’s fair market value from property tax, so owner-occupants pay tax on only 55% of value. Second homes and investment property don’t qualify and are taxed on the full value.
Do I need to apply for Utah’s primary residential exemption?
Most counties apply it automatically once you own and occupy the home, though some require a Residential Property Declaration, particularly if your mailing address differs from the property address. Only one property per household statewide can claim it.
Why do Utah property tax rates vary so much by county?
Each of Utah’s 29 counties, along with cities and school districts within them, set their own rates through the state’s truth-in-taxation process, producing effective rates that range from about 0.26% to 0.80% on a primary residence.
Is there property tax relief for seniors in Utah?
Yes, Utah’s Circuit Breaker Homeowner’s Credit provides a sliding-scale abatement for qualifying homeowners 66 or 67 and older with household income under roughly $44,000, plus an additional credit tied to 20% of home value.
Does Utah charge a real estate transfer tax?
No. Utah is one of the few states with no state or local real estate transfer tax. Buyers and sellers only pay modest county recording fees related to the deed.
How accurate is this mortgage calculator with taxes and insurance?
The principal and interest math is exact. County tax figures reflect published effective rates already net of the 45% exemption, while insurance and PMI are market-based estimates that may vary once a lender underwrites your loan.
Should I choose a 15-year or 30-year mortgage in Utah?
A 15-year term carries a lower rate and less total interest but a higher payment. A 30-year term keeps payments lower and more flexible, which is why most buyers choose it.
What down payment do I need to buy a home in Utah?
Conventional loans often start around 3 to 5% down, FHA loans typically require 3.5%, and VA loans can allow 0% down for eligible veterans.
Does this calculator include Utah closing costs?
No. This tool focuses on your ongoing monthly payment. Utah has no transfer tax, but you’ll still pay lender fees, title insurance, and other closing costs, typically 2% to 5% of the loan amount.
