What is Nexus?

You'll need to collect sales tax in Massachusetts 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 Massachusetts

Physical Nexus

Physical nexus is the classic way to have a nexus and happens when your business has a real, physical presence in Massachusetts. This includes:
  • An office, warehouse, or store
  • Workers living or working in the state
  • Storing inventory or property in Massachusetts
If your business is physically rooted in the state, you need to start collecting and remitting sales tax for Massachusetts transactions.

Economic Nexus

Economic nexus kicks in when your sales or transactions in Massachusetts hit a certain level, even if you're not physically there. In Massachusetts, you get economic nexus if you have:
  • Over $100,000 in sales, or
  • 200 or more separate transactions in the state within a year
Crossing this threshold means it's time to handle Massachusetts sales tax.

Affiliate Nexus

Affiliate nexus happens when your business is connected to another company or individual in Massachusetts that helps with sales. This can be through:
  • A subsidiary or parent company in the state
  • Sales agents, reps, or independent contractors in Massachusetts
Having this kind of link in the state means you might need to collect and remit sales tax.

Click-Through Nexus

Click-through nexus is all about online connections. If your business teams up with someone in Massachusetts who refers customers through a website link or ad, and you make:
  • Over $10,000 from these referrals, and
  • At least $500,000 in total state sales in the last year
Then, you've got click-through nexus and need to manage sales tax on those transactions.

Marketplace Nexus

Marketplace nexus is about selling through online platforms like Amazon or eBay that are present in Massachusetts. Usually, these platforms handle the sales tax for you. But, it’s smart to keep an eye on your sales to make sure the right amount of sales tax is being collected and paid.

Massachusetts doesn't tax alcohol. It’s the spirit of the Boston Tea Party, with a twist. Which is exactly how I like my gin martinis: with Monkey 47 by Schwartzwald and a lemon twist. If you have a favorite gin full of unique floral botanicals, send me a note at! I’d love to try it.
