Prior to the South Dakota v. Wayfair, Inc. decision, the Commonwealth of Massachusetts had updated its economic nexus provisions to include economic nexus as well as “cookie nexus,” which allowed internet cookies on customer devices to trigger nexus in a jurisdiction. Since that time, the Massachusetts Department of Revenue updated details on the Massachusetts economic nexus in 2019. We have highlighted several key points for remote sellers and marketplace facilitators.
Enforcement date: 
October 1, 2019.
Sales/transactions threshold:
$100,000.
Measurement period:
Threshold applies to the previous or current calendar year.
Included transactions/sales:
Retail sales of tangible personal property delivered into the state.
When You Need to Register Once You Exceed the Threshold:
If remote seller or marketplace sales exceeded $100,000 prior to November 1 of that preceding year, the seller or marketplace must begin collection and remittance as of January 1. If those sales exceeded $100,000 after November 1 of that year, the seller or marketplace must collect and remit as of the first day of the first month beginning two months after the month when the threshold was exceeded.
Summary: Prior to October 1, 2019, a seller was obligated to collect Massachusetts tax if they deposited cookies (bits of software that facilitate user experience on a website) on the devices of Massachusetts residents and made more than 100 transactions or $500,000 in revenue from Massachusetts customers. Massachusetts marketplace liability rules require “marketplace facilitators” and “remote marketplace facilitators” with sales exceeding $100,000 to report, collect, and remit on all such sales, whether such sales are direct sales by the marketplace facilitator or sales facilitated for a marketplace seller.
