What is Nexus?

You'll need to collect sales tax in Maine 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 Maine

Physical nexus in Maine is like having a tangible piece of your business anchored in the state. This could be:

  • Having employees, agents, or sales reps waving your flag in the state.
  • Storing inventory or merchandise, even in someone else's warehouse.

Economic Nexus in Maine

Economic nexus is about your business’s financial waves in Maine. It kicks in if, during the current or previous year, you:
  • Hit over $100,000 in gross revenue from sales of products or services in Maine, or
  • Had 200 or more separate transactions delivering into Maine.

  • You have a significant ownership link with, or are owned by, a company rooted in Maine, or
  • You share management, business systems, or employees with a Maine-based company.

Click-Through Nexus in Maine

Click-through nexus sets sail when you've got an agreement with a Maine-based affiliate who sends customers to you via a website link or other means, generating over $10,000 in sales from those referrals in the previous year.

Marketplace Nexus in Maine

Marketplace nexus is for those sailing the online marketplace seas. In Maine, marketplace facilitators must collect and remit sales tax for their sellers if their sales, or combined sales with marketplace sellers, meet Maine's economic nexus thresholds.
