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 additional mass transit tax, 0.25 percent county option transportation tax, 0.25 percent transportation infrastructure tax, 0.2 percent county public transit tax, 0.5 percent rural hospital tax and 0.1 percent botanical, cultural and zoo tax, which puts the countywide floor at 7.65 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 9.55 percent is at Park City, which adds a 0.3 percent mass transit tax and 1.6 percent resort community tax. The unincorporated county is not the floor here: it carries its own resort community tax and sits at 8.75 percent. Food and food ingredients are taxed at 3 percent statewide instead of the combined rate, so these figures are general merchandise only.

How do I find the exact rate for an address in Summit County?

Use Utah's own address lookup. In Summit County the rate depends on the address, anywhere from 7.65% to 9.55%.
