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 0.3 percent mass transit fixed guideway tax and 0.25 percent county option transportation tax, which puts the countywide floor at 6.65 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 8.65 percent is at Brian Head, which adds a 0.3 percent highways tax, 0.1 percent botanical, cultural and zoo tax and 1.6 percent resort community tax. Food and food ingredients are taxed at 3 percent statewide instead of the combined rate, so these figures are general merchandise only.
