The residential exemption, what a South Jordan or Herriman bill looks like, and the reset that does not happen when you buy.
Utah taxes a primary residence on only 55% of its market value. That is the residential exemption, and it is the single most important thing to understand about a Utah tax bill. A $700,000 South Jordan home is assessed for tax purposes at $385,000, and the local rate is applied to that figure — which is why the effective rate on a primary residence typically lands around 0.55% to 0.65%, or roughly $3,900 to $4,600 a year on that $700,000 home as of 2026.
The exemption applies to your primary residence and to long-term rentals. It does not apply to a second home or a short-term rental, which are taxed on 100% of value — close to double the bill on an identical house.
And unlike California, buying does not reset your assessment upward to the purchase price. Utah counties reassess on their own cycle, so a purchase is not the triggering event. Verify current rates with the Salt Lake County Assessor and Treasurer rather than relying on a listing estimate, which is frequently the prior owner's bill.
A 45% reduction in the taxable value of a primary residence. Your home is assessed at market value, then only 55% of that value is taxed. It applies automatically to a primary residence and to residential property rented long term, and it is the reason Utah’s effective residential rates sit well below its headline rates.
As of 2026, plan on roughly 0.55%–0.65% of market value annually for a primary residence — about $3,900–$4,600 on a $700,000 home. Rates vary by tax district, so Herriman, Riverton, South Jordan and Draper each differ slightly, and a home inside a special service or improvement district pays more. Confirm your exact district with the county before budgeting.
November 30 for the calendar year, billed in arrears. If your mortgage escrows taxes your servicer pays it; if not, it is one payment, not two. At a closing the year is prorated to the closing date, so a seller closing in September credits the buyer for roughly three quarters of that year’s bill.
Not because you bought it. Utah has no acquisition-value reassessment, so unlike California there is no purchase-triggered reset to your price. Counties revalue on their own cycle and your assessment will move with the market over time, but the sale itself is not the event that moves it.
They lose the 45% exemption and are taxed on 100% of market value, which roughly doubles the bill relative to an identical primary residence. If you are modeling a Park City or St. George second home, or a short-term rental anywhere in the state, run the numbers without the exemption or the pro forma will be materially wrong.
Yes. Appeals go to the County Board of Equalization, generally by mid-September for that year’s valuation, and the case you make is comparable sales evidence that your assessed market value is too high. Because Utah is a non-disclosure state, assembling those comparables usually means asking a brokerage with MLS access — which is a normal request and one we take.
You pay on the land while it is vacant, and the improvement enters the roll once it is substantially complete, prorated for the portion of the year it existed. On a new build in Daybreak or Herriman that means your first full-year bill is meaningfully higher than your partial-year one, which catches people the following November.
Utah offers additional relief for qualifying veterans with a disability rating, for blind claimants, and a circuit-breaker abatement for low-income seniors, plus county indigent abatement and deferral programs. Eligibility and amounts change; apply through the county, and check each year rather than assuming last year’s answer holds.
Utah’s effective residential property tax rate is among the lower ones in the country, materially below Texas or Nebraska and roughly in line with Colorado. Combined with no real estate transfer tax, the total cost of owning and transacting in Utah is lower than in most of the states people relocate from. Income and sales tax are separate questions.
We do it as part of every buyer consultation, because the listing’s tax figure is often the previous owner’s bill and can be badly stale on a home that changed use. The Moser Group at Premier Real Estate works out of South Jordan and has closed more than 1,500 Utah transactions. Call 801-699-0525 and we will pull the actual parcel record.
