Why the rate here is not the whole story
Wyoming's state sales and use tax is 4 percent and Uinta County levies a 1 percent general purpose county option tax, for a total of 5 percent. Wyoming county option taxes are approved by a county-wide referendum and carry a term that expires, either on a date or once a set dollar amount has been collected, so a county's rate can change at the start of any calendar quarter and rates more than a few months old go stale. The county line is not the tax boundary in Wyoming: under W.S. 39-15-204(a)(vii) any city or town may levy its own tax of up to 1 percent inside its limits, and under W.S. 39-15-204(a)(v) a resort district may levy up to 3 percent inside its boundaries. No Wyoming city levies today, since Casper's 1 percent municipal tax ended on June 30, 2026, and only the two resort districts in Teton County do. Wyoming exempts food for domestic home consumption from both the state and the county tax under W.S. 39-15-105, so groceries are untaxed while prepared food, alcoholic beverages and tobacco are not. Wyoming also charges a separate statewide and local lodging tax, which is a different tax and is not included in any rate here. The Department's own address level rate lookup is marked as still under construction, so the linked page is its rate chart and zip code chart instead.
