Do you have sales tax nexus in Massachusetts? 

Sales tax nexus—the connection between a seller and a state that requires the seller to collect and remit sales tax—is a crucial concept for businesses, especially those that operate in multiple states. There are two types of nexus: physical and economic. Physical nexus occurs when a business has a tangible presence in Massachusetts, such as an office, warehouse, or employees. Economic nexus is established when a business reaches a certain sales threshold, even without physical presence. We break down more details about nexus below. 

Physical sales tax nexus in Massachusetts 

Some examples of physical sales tax nexus in Massachusetts include: 

  • Having a business location in Massachusetts 
  • Having representatives soliciting orders or telecommunications services within Massachusetts 

Economic sales tax nexus in Massachusetts 

Economic nexus in Massachusetts is triggered when a business with no physical presence in the state makes over $100,000 in sales to Massachusetts customers in a calendar year.  

Determining nexus for your business can be a complex and daunting task. With many factors to consider, many businesses struggle to navigate the intricacies of nexus determination, and even end up paying thousands of dollars to accounting firms to get answers. That’s why we offer nexus determination as an a-la-carte or package deal for businesses at affordable prices. With over 20 years of experience in federal and state tax and accounting laws, we’re a trusted partner for many businesses in need of nexus review services. Contact us now for a consultation! 

Are marketplace facilitators required to collect and remit sales tax in Massachusetts? 

In Massachusetts, marketplace facilitators are responsible for collecting and remitting sales tax on behalf of their sellers. Key points to keep in mind include: 

  • Massachusetts law requires marketplace facilitators to collect and remit sales tax when their sales volume exceeds $100,000 annually
  • This requirement applies even if the individual sellers on the platform do not meet the sales threshold themselves. 
  • Businesses using marketplace facilitators should ensure they are aware of the facilitator’s compliance with Massachusetts sales tax laws. 

What platforms are marketplace facilitators? 

  • Amazon    
  • eBay    
  • Etsy    
  • Walmart (online)    

Not sure what defines a marketplace facilitator? In short, marketplace facilitators are companies that provide a platform or service for third-party sellers (you) to sell their products or services to customers. The facilitator collects payment from the customer, processes the transaction, and may also manage shipping and returns.
