Do you have sales tax nexus in Wyoming?
Nexus is the connection that obligates your business to collect and remit Wyoming sales tax. You can establish it two ways — physically or economically. Either one is enough.
Physical nexus
You have physical nexus if you have a tangible presence in Wyoming, such as:
- A physical presence such as an office, warehouse, or distribution center in Wyoming
- Employees or representatives soliciting sales in Wyoming
- Regularly soliciting through advertising or electronic media directed at Wyoming consumers
- Inventory stored in the state
Economic nexus
Out-of-state sellers establish economic nexus once gross sales into Wyoming exceed $100,000 in the current or previous calendar year. Wyoming uses a dollar threshold only — it removed the former 200-transaction test (effective July 1, 2024).
What is taxable in Wyoming?
Most tangible goods are taxable, with exceptions for certain groceries and prescription medicine. Services are generally exempt, except those involving the sale, repair, alteration, or improvement of tangible personal property.
Is SaaS taxable in Wyoming?
No. Wyoming does not tax SaaS — the purchaser doesn’t gain permanent use of the software. (Downloaded prewritten software can be taxable.)
How is food taxed in Wyoming?
Food intended for home consumption (including bakery goods sold without utensils for off-premises consumption) is exempt. Meals and cover charges where meals are regularly served are taxed at the full rate.
How to register for a Wyoming sales tax permit
Obtain a Wyoming sales tax license before collecting. Taxually can register for you, or you can apply online through the Wyoming Internet Filing System for Businesses (WYIFS) or by paper. A one-time $60 license fee applies.
Have ready: personal identification (SSN, address), business identification (EIN, address), your date of first Wyoming sale, and information about the products you sell.
How to collect sales tax in Wyoming
Wyoming is destination-based — collect at the rate for the delivery location. For example, Cheyenne is 5% (4% state + 1% county). This applies whether you’re based in Wyoming or selling remotely.
Filing and paying Wyoming sales tax
Filing frequency is set by monthly collections: monthly (more than $150/month), quarterly ($50–$150/month), or annual ($0–$50/month). Returns are due the last day of the month following the period. File by the 15th to earn a timely-filing credit (1.95% on the first $6,250 of tax and 1% above, capped at $500 per period).
File online through WYIFS or by paper (Forms 41-1/42-1). Taxually’s software automates the full process.
Penalties for late or non-compliant filing
Failing to file or pay on time triggers these penalties:
- Late payment: 10% of the tax due.
- Late filing: $10, regardless of the tax due (plus an additional $25 if you don’t file within 30 days of a Department notice).
- Interest accrues at the annual rate set by the Department.
