Massachusetts Sales Tax Nexus: Economic Nexus Threshold (2026)
Massachusetts's economic nexus threshold for remote sellers is $100,000 in sales, measured over the prior calendar year or current calendar year. Sales made through marketplace facilitators do not count toward your own Massachusetts threshold. Inventory or another physical presence in Massachusetts generally creates nexus regardless of sales. The state rate is 6.25%.

What to do after crossing the Massachusetts threshold
When it starts:
- Start date: if the prior year's sales exceeded $100,000 before November 1, collection starts January 1; if the threshold is crossed on or after November 1 or during the current year, collection starts the 1st day of the 1st month beginning two months after the month the threshold was exceeded.
- Confirm the numbers. Check your Massachusetts sales against the measure and period in the key facts above.
- Register before you collect. Use Massachusetts's official registration page. Collecting a state's tax without a registration is generally not allowed.
- Collect and file. Charge Massachusetts sales tax on taxable sales from the start date, and file returns on the schedule the state assigns. Marketplaces generally collect on the sales they facilitate, so you usually collect on your direct sales.
- Look back. If you crossed the threshold in an earlier period and did not register, get advice on those periods. Many states have voluntary disclosure programs that may limit penalties.
Physical presence and inventory in Massachusetts
DOR treats sellers with Massachusetts stores, employees, inventory or representatives as in-state sellers that must collect regardless of volume; inventory in Massachusetts (including FBA/3PL) generally creates physical nexus.
Marketplace sellers in Massachusetts
Do marketplace sales count toward your own threshold? No, excluded.
DOR FAQ: 'When a marketplace collects tax on a Massachusetts sale on behalf of a marketplace seller, does that sale count towards the seller's $100,000 threshold? No, only the direct Massachusetts sales by a marketplace seller are counted towards the $100,000 threshold for such seller.' Marketplaces count both facilitated and their own direct sales toward their own $100,000 threshold. Marketplace sellers are relieved of liability for facilitated sales when they receive the marketplace's collection certificate (Form ST-16) in good faith.
