Sales tax in Park County, Wyoming

What is the sales tax rate in Park County?

Why the rate here is not the whole story

Wyoming's state sales and use tax is 4 percent and Park County levies no county option tax, so the total is 4 percent. Park County is one of two Wyoming counties levying no county option tax at all, so the rate there is the bare 4 percent state tax. The Department's Streamlined rate file carries an explicit zero record for Park County rather than no record, which is a positive confirmation rather than a gap. The county may levy up to 3 percent if its voters approve it. 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.

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

The rate is the same across Park County, but if you are collecting tax it is worth confirming against the source. Use Wyoming's own lookup. A vendor's calculator is not the state speaking.
