Who must register for Wyoming sales tax
You must register for a Wyoming Sales Tax License if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales or 200 or more separate transactions into Wyoming in the current or previous calendar year, or;
- Has a physical presence in Wyoming, such as an office, employee, warehouse, or inventory stored in the state.
Wyoming's dual threshold means you must register once you cross either the dollar amount or the transaction count, whichever comes first.
Once you exceed the threshold, you should register before making further taxable sales in Wyoming. Wyoming imposes a 4% state sales tax. Counties add their own local sales taxes on top of the state rate, typically between 1% and 2%, so the actual combined rate depends on the buyer's location within Wyoming.
If you're unsure whether your business has nexus, see the Wyoming Sales Tax Guide for a broader explanation.
How to register for Wyoming sales tax
Sellers can register online through Wyoming Revenue Online, the state's centralized tax portal. This is the same portal you will use to file returns and make payments after registration.
Information you need before registering
Before applying for a Wyoming Sales Tax License, have this information ready:
- Your Social Security number (if registering as a sole proprietor with no employees)
- Your Employer Identification Number (EIN), if your business has one (required for corporations, partnerships, and most LLCs)
- North American Industry Classification System (NAICS) code for your primary business activity
- The date of your first sale in Wyoming

1. Create your online login

2. Provide your business information

- Remote sellers without a Wyoming location should indicate they are selling remotely
- Wyoming uses destination-based sourcing for remote sellers, meaning you charge the rate based on where the buyer is located
- Wyoming's county rate structure means the applicable combined rate depends on which county the buyer is in

What happens after registration
After registering, you must begin collecting Wyoming sales tax on taxable sales and file returns based on your assigned filing frequency. Note that Wyoming sales tax returns are due on the last day of the month following the reporting period, which differs from most states that use the 20th.
Wyoming generally taxes digital goods and SaaS, so if you sell software or cloud-based services, those sales are subject to Wyoming sales tax. See the Wyoming Sales Tax Guide for details on taxability.
