Why the rate here is not the whole story

Utah charges 4.85 percent statewide, and a 1 percent local sales tax and a 0.25 percent county option sales tax apply at every address in the state, so no location in Utah is taxed below 6.1 percent on general merchandise. Everywhere in this county also pays 0.25 percent transportation infrastructure tax and 0.1 percent botanical, cultural and zoo tax, which puts the countywide floor at 6.45 percent. Cities, towns, resort communities, transit districts and special service districts then levy on boundaries that do not follow county lines, so a single rate for the whole county does not exist. The ceiling of 8.38 percent is at Springdale, which adds a 1.6 percent resort community tax and 0.33 percent emergency services tax. On October 1 2026 Washington City and Hildale began charging the same 0.33 percent emergency services tax the other seven towns already charge, and Toquerville added a 0.3 percent highways tax, so Washington City and Toquerville are now at 7.08 percent and Hildale at 6.78 percent. All three remain below the ceiling, so the range did not change. Food and food ingredients are taxed at 3 percent statewide instead of the combined rate, so these figures are general merchandise only.
