County voters set every rate above 4%

Each county may layer optional excise taxes on the 4% state rate, put to the electors by petition or by resolution of the county and half its municipalities. Each has its own purpose, cap and duration.[3]

General purpose tax, capped at 1% Economic development tax, capped at 1% Specific purpose tax for named projects Lodging tax Petition by 5% of electors, or county resolution Specific purpose taxes end when the money is raised
Not every county tax expires any more. Legislation effective July 2021 extended initial terms from two years to four and allows a general purpose tax to be made permanent, so the old rule of thumb no longer holds.[3]

Rates & Registration

County general purpose taxUp to 1%
County economic development taxUp to 1%, in 0.25% steps
County specific purpose taxEnds when the amount is raised
County lodging taxAdopted by referendum

Because a specific purpose tax ends the moment its approved dollar amount has been collected, a county rate can fall mid-year with no legislative action at all.[3]

Who must register

Either trigger applies: economic nexus at more than $100,000 of gross revenue from sales of goods, admissions or services delivered into Wyoming in the current or immediately preceding calendar year, or any physical presence. The 200-transaction alternative was dropped effective 1 July 2024.[4]

Solicitation can create nexus on its own: from July 2025 the definition of a vendor reaches sellers making three or more separate advertising transmittances targeting Wyoming consumers in a twelve-month period, independently of the dollar threshold.[5]

Compliance

Sales Tax Registration and Filing

Apply for a Wyoming sales tax licence before making taxable sales.

How to register

  • Confirm nexus→
  • Sales & use tax application→
  • Licence issued→
  • Map county rates→
  • File electronically

A direct pay permit is available but is positioned for businesses with taxable purchases above $5 million a year, so it is not a general alternative to vendor collection.[7]

Confirm your assigned frequency and due dates with the Department when your licence is issued, since the assignment depends on expected volume.[8]

Taxability

Taxable vs. exempt

Wyoming taxes tangible goods, admissions and specified services, exempts groceries, and taxes prepared food at the full combined rate.[2]

Generally taxable

  • Tangible retail goodsW.S. Title 39 Ch. 15
  • Prepared food & restaurant mealsSold with utensils
  • AdmissionsW.S. Title 39 Ch. 15
  • LodgingPlus county lodging tax
  • Specified services delivered in stateW.S. Title 39 Ch. 15
  • Goods used in state without tax paidUse tax

Generally exempt

  • Food for domestic home consumptionGrocery exemption
  • Manufacturing machinery used in stateW.S. 39-16-105
  • Sales for resaleWith exemption certificate
  • Sales to government bodiesW.S. Title 39 Ch. 15
  • Goods delivered out of stateInterstate commerce
  • Prescription drugsW.S. Title 39 Ch. 15
Worth flagging: the grocery exemption is deliberately hedged. The Department’s own wording is that most, but not all, food sold at grocery stores qualifies, so items in a grocery store that meet the prepared-food test are taxable even when they sit beside exempt groceries.[2]
Reference

FAQ

Sales Tax FAQs

4% at state level. Counties may add optional taxes approved by referendum, so combined rates generally run between 4% and 8% depending on which county the customer takes possession in.

Each county may adopt general purpose, specific purpose, economic development and lodging taxes by referendum, called either by a petition signed by at least 5% of the electors or by resolution of the county and at least half its incorporated municipalities. Each levy has its own cap and duration.

Some do. A specific purpose tax ends automatically once the dollar amount named on the ballot has been collected, so its end date is not knowable in advance. Since July 2021, however, a general purpose tax may be adopted for four years or made permanent, so not every county tax carries an expiry.

No. Food for domestic home consumption is exempt. Prepared food, which the Department describes as food typically sold with utensils and designed for immediate consumption, is taxable, and so are alcoholic beverages.

More than $100,000 of gross revenue from goods, admissions or services delivered into Wyoming in the current or immediately preceding calendar year. The 200-transaction alternative was dropped effective 1 July 2024.

A timely-filing vendor may retain 1.95% of the first tranche of tax due and 1% of the excess, with the total credit capped at $500 in any month across the sales and use tax credits.
