What is Nexus?

You'll need to collect sales tax in Missouri 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 Missouri

Physical Nexus

You’ve got physical nexus in Missouri if your business has a real presence there. This can be through:
  • Owning or leasing a place like an office, warehouse, or store
  • Having employees in the state
  • Keeping inventory in a Missouri warehouse, even if it’s not yours
Participating in trade shows or making sales face-to-face in Missouri

Economic Nexus

Economic nexus comes into play when your sales in Missouri hit a certain level, regardless of physical presence. Since January 1, 2023, Missouri’s rules say you’ve got economic nexus if:
  • Your business makes over $100,000 from selling tangible personal property delivered into Missouri in the previous or current calendar year

Affiliate Nexus

Affiliate nexus in Missouri happens when your business partners with a local company or person to boost sales. This includes:
  • Contracts with Missouri affiliates for customer referrals in exchange for commission
  • Using a local company for services like repairs, maintenance, or delivery

Click-Through Nexus

Missouri hasn’t explicitly mentioned click-through nexus in its sales tax laws. But, a strong affiliate relationship with a local company could create an affiliate nexus, as we mentioned earlier.

Marketplace Nexus

Marketplace nexus is for those using platforms like Amazon, eBay, or Etsy to sell stuff. Since January 1, 2023, Missouri requires these marketplace facilitators to collect and send in sales tax on behalf of sellers if their sales into Missouri go over $100,000 in a year.
