What is Nexus?

You'll need to collect sales tax in Idaho 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 Idaho

What Triggers Sales Tax Nexus in Idaho?

Nexus in Idaho is all about your business's presence or activities in the state. Here's how it works:

Physical Nexus

This happens when your business has a noticeable physical presence in Idaho. It could be:
  • An office, warehouse, or store in Idaho.
  • Employees or agents in the state.
  • Owning or leasing property in Idaho.
  • Delivering goods in your vehicles in Idaho.

Economic Nexus

Even without a physical presence, if your sales are big in Idaho, you might have economic nexus. Here's Idaho's take:
  • Delivering goods in your vehicles in Idaho.
  • More than 200 separate transactions in Idaho, in the current or previous year.

Affiliate Nexus

Got a partnership with an Idaho business that helps you make sales? This could create affiliate nexus. If your agreement with an Idaho business leads to over $100,000 in sales or you pay them a commission, you're in this category. To steer clear, you'd need to avoid such agreements or keep sales under that threshold.

Click-Through Nexus

This is similar to affiliate nexus but with a lower sales threshold. If you get over $10,000 in sales through Idaho referrals, you're here. To avoid this, don't have these agreements or keep sales from them under $10,000.

Marketplace Nexus

For marketplace facilitators like Amazon or Etsy, if you or your affiliates get over $100,000 in sales in Idaho, you've got marketplace nexus. You'd then need to collect and remit sales tax on all Idaho sales.

Got Nexus? Here's What to Do

If any of these apply to you:
  • Get an Idaho seller's permit.
  • Collect Idaho sales tax from your customers.
  • File sales tax returns, monthly or quarterly, based on your sales volume.
  • Send the collected tax to the Idaho State Tax Commission.
