Wyoming sales tax starts at a 4% state rate on most retail purchases, and counties and resort districts can add their own layers on top, pushing the total you pay at the register to as much as roughly 7% in high-tourism areas.1Justia Law. Wyoming Code 39-15-104 – Taxation Rate Because Wyoming has no personal or corporate income tax, that sales tax carries a heavy share of funding for roads, schools, and public services.
How the Combined Rate Is Built
The 4% state rate is set by the legislature and applies uniformly across all 23 counties before any local tax is layered on. Counties can add their own taxes once voters approve them, generally in two forms: a general-purpose tax that funds broad county services, and a specific-purpose tax earmarked for projects like road improvements or public facilities.2Justia Law. Wyoming Code 39-15-204 Each typically adds 1%, and more than one can be stacked.
Resort districts, which cover areas built around seasonal tourism, can impose a further tax to help pay for serving visitors. Teton Village levies a 2% resort district tax on top of the state and county rates. In a county with no local tax, you pay 4%; in Teton County, the total runs close to 7%.
What Wyoming Taxes
Sales tax covers nearly every retail purchase of physical goods: clothing, electronics, furniture, vehicles, and the rest of what sits on store shelves. It also reaches a specific list of services:
- Admissions to movies, sporting events, concerts, and other amusements.
- Short-term lodging — hotel, motel, and vacation rental stays of fewer than 30 consecutive days.
- Telecommunications, including phone and internet service charges.
- Leases and rentals of physical goods such as equipment or vehicles.
- Repair and maintenance labor on physical property, including the parts and materials used in the work.3Cornell Law Institute. Wyoming Code of Rules 2-12 – Specific Taxability Issues
Services not on this list — legal advice, medical consultations, accounting, engineering, and most other professional work — fall outside the sales tax base entirely.
What’s Exempt
Groceries bought for home consumption are exempt, so your regular supermarket trip won’t carry the 4% charge. Prescription drugs and insulin are also exempt, though over-the-counter medications are not. Sales to federal, state, and local government entities are untaxed, and so are sales to qualifying religious and charitable organizations when the purchase supports their regular functions.4Justia Law. Wyoming Code 39-15-105 – Exemptions
Manufacturing and Agriculture
Materials that become an ingredient or component of a finished product, along with containers, labels, and shipping cases, are exempt when a manufacturer buys them.5Wyoming Legislature. Wyoming Sales and Use Tax Exemptions Chemicals and catalysts consumed during manufacturing are treated the same way. Through December 31, 2027, the sale or lease of machinery used directly and predominantly in manufacturing is also exempt, provided the buyer is classified under NAICS manufacturing sectors 31 through 33.
On the farm side, livestock, animal feed held for marketing, seeds, fertilizer, and small plants intended for commercial sale are exempt. Farm implements designed and used exclusively for agricultural work qualify as well, but titled vehicles, snowmobiles, lawn tractors, and ATVs do not. Power and fuel consumed directly in manufacturing or agriculture are exempt too.
Use Tax on Purchases From Out of State
Buying something from an out-of-state seller who doesn’t collect Wyoming sales tax doesn’t get you out of paying. You owe a use tax at the same 4% state rate, plus any local rate for your county.6Justia Law. Wyoming Code 39-16-104 – Taxation Rate Vehicles purchased out of state are subject to use tax before you can register them in Wyoming. If the seller didn’t collect, you report and pay the Department of Revenue directly, due the last day of the month following the purchase.
Remote Sellers and Online Marketplaces
Out-of-state businesses must register, collect, and remit Wyoming sales tax once their gross revenue from sales delivered into the state exceeds $100,000 in the current or previous calendar year.7Justia Law. Wyoming Code 39-15-501 – Sales From Remote Sellers Wyoming dropped its separate 200-transaction threshold in July 2024, leaving the dollar amount as the only trigger. Once you cross it, you must register before your next sale into the state.
If you sell through a marketplace like Amazon or Etsy, the marketplace facilitator collects and remits the tax on those orders, not you.8Justia Law. Wyoming Code 39-15-502 – Marketplace Facilitators Sales the marketplace handles don’t count toward your personal $100,000 threshold. The facilitator has to collect on all facilitated Wyoming sales regardless of whether the individual seller has a permit.
If You Sell in Wyoming: Registering and Filing
Any business making taxable sales in Wyoming needs a sales tax license before it starts operating. You can apply online through the Wyoming Internet Filing System for Business (WYIFS) or mail a paper application to the Department of Revenue in Cheyenne.9Excise Tax Division. WYIFS There’s a one-time $60 registration fee, and the license stays valid as long as you keep operating and filing — no renewal fee.
Returns are due on the last day of the month following the reporting period.10Justia Law. Wyoming Code 39-15-107 – Compliance A vendor reporting January sales files and pays by the last day of February. Most file monthly; the Department of Revenue may assign a quarterly or annual schedule to lower-volume businesses. Even if you had zero taxable sales for a period, file a return showing $0. Skipping it can trigger penalties.
Vendor Credit and Late-Payment Penalties
Wyoming compensates businesses for collecting the tax through a vendor collection credit, but only if you pay by the 15th of the month it’s owed rather than waiting for the last-day deadline.11Wyoming Department of Revenue. Vendor Compensation Credit The credit is 1.95% on the first $6,250 of tax due and 1% on anything above that, capped at $500 per month across sales and use tax combined. A business remitting $5,000 for a given month and paying by the 15th would claim about $97.50.
Miss a deadline and interest starts running. The rate is set each January at the state treasurer’s average prime rate for the preceding fiscal year plus four percentage points, capped at 18%.12Justia Law. Wyoming Code 39-15-108 – Enforcement On top of interest, the Department of Revenue can assess a 10% penalty on the underpaid amount for negligence or careless disregard, or 25% for fraud or intentional evasion. Filing a corrected return promptly after catching an error helps limit the interest that accrues.
