Massachusetts Nexus Rules 2024 Massachusetts: Sales Tax Handbook


What constitutes sales tax nexus in Massachusetts?

One of the more complicated aspects of Massachusetts sales tax law is sales tax nexus, the determination of whether a particular sale took place within the taxation jurisdiction of Massachusetts, and is thus subject to state (and possibly local) sales taxes.

If a vendor's transactions are determined to have nexus in Massachusetts, the vendor must register for a Massachusetts sales tax license and collect appropriate sales taxes from the buyer for all transactions with nexus in the state. On this page, we have compiled some of the most commonly needed facts about what constitutes sales tax nexus in Massachusetts.

Sales Tax Nexus in Massachusetts

According to the Massachusetts law, retailers who have tax nexus must be vendors who are "engaged in business" in the commonwealth. This can be defined in several different ways. If your business keeps goods in a warehouse within the state, has an office, any place of business, or any owned property in the state, there is delivery of property or performance of a service in Massachusetts, has a sample or display area(such as a trade show or craft fair) within the state's boundaries, owns a real or personal property in Massachusetts, or an employee who is present in the commonwealth for greater than two days each year has tax nexus in the state of Massachusetts.

Taxation of Internet-Based Sales in Massachusetts

NOTE: 2018 Supreme Court Ruling Regarding Online Sales Taxes

In the 2018 Supreme Court case South Dakota vs. Wayfair Inc, Et Al., the court overturned a previous ruling that required a merchant to have physical nexus in order for a state to collect sales tax. This means that any state is now free to enforce collection of sales taxes on out-of-state online merchants. The information provided here may be subject to change, and many states are expected to begin collecting online sales taxes following this ruling.

Depending on the situation, Massachusetts may or may not charge sales tax on Internet-based transactions. Massachusettes's statute does indicate that it is possible for tax nexus to exist. However, in the case Quill Corp. v. North Dakota, the U.S. Supreme Court declared that due to the Commerce Clause, a seller must have a physical presence in the state of Massachusettes for the state to legally require the seller to collect sales tax
