How Local Sales Tax Works in Wyoming
Wyoming counties may adopt general purpose, specific purpose and economic development local option taxes on top of the 4% state rate, each approved by county voters and each with its own expiry date. Because they lapse and are re-voted, Wyoming county rates change more often than in most states — several jurisdictions reduced their rates during 2026.
Which Wyoming Rate Should You Charge?
Wyoming is destination-sourced and a Streamlined Sales and Use Tax Agreement member, so the county rate that applies is the one covering the delivery address.
What Wyoming Taxes — and What It Doesn’t
Groceries for home consumption and prescription drugs are exempt. Most services are untaxed. Wyoming has no personal or corporate income tax, so sales and mineral taxes carry much of the state’s revenue.
