What is Nexus?

You'll need to collect sales tax in Wyoming if you have nexus there. There are two main ways that sellers can be tied to a state when it comes to nexus: physical, or economic.

Physical nexus means having enough tangible presence, or activity in a state to merit paying sales tax in that state.

Economic nexus means passing a states' economic threshold, for total revenue, or the number of transactions in that state.

Calculating Nexus in Wyoming

Physical Nexus

You get physical nexus in Wyoming if you have a presence like a warehouse or office. The Wyoming Department of Revenue says you have physical nexus if you:
  • Have a business location in Wyoming.
  • Have employees or sales agents in the state.
  • Provide warranty repairs in Wyoming.
If you're doing any of these, you're expected to collect and pay Wyoming sales tax.

Economic Nexus

Economic nexus is about your sales level in Wyoming. It kicks in if you:
  • Make over $100,000 in sales or,
  • Have 200 or more transactions in the state in a year.
This applies even if you don't have a physical presence in Wyoming.

Affiliate Nexus

It's different from economic nexus, focusing on your business relationship in Wyoming. Examples include:
  • A subsidiary in Wyoming selling your products online.
  • An affiliate in Wyoming reviewing your products on a blog.
  • A Wyoming affiliate promoting your products on social media.
Not sure about affiliate nexus? It's wise to consult a tax advisor.

Click-Through Nexus

Wyoming doesn't have click-through nexus laws yet. You establish nexus either through economic or affiliate nexus, like hitting over $100,000 in sales or having an affiliate in the state. Stay tuned, though, as laws can change.

Marketplace Nexus

Marketplace nexus is about using platforms like Amazon. You have it if:
  • You make $100,000 or have 200+ transactions in Wyoming in a year.
  • You have a physical presence in Wyoming.

It's about using platforms to sell in Wyoming, not just your sales volume. If you're a marketplace facilitator selling in Wyoming, make sure you know these rules.
