What this means for remote sellers

Massachusetts uses a revenue-only economic nexus threshold. You establish nexus once your gross sales into Massachusetts reach $100,000 during current or previous calendar year. The number of separate transactions does not affect the threshold.

How Massachusetts compares to other states

Massachusetts's $100,000 revenue threshold is the most common in the country — 42 jurisdictions use it. It is one of 29 jurisdictions that look at revenue only — the number of transactions does not count. Its 6.25% base sales-tax rate sits above the roughly 5.7% average state rate.

How the Massachusetts threshold is measured

Massachusetts measures the threshold over Current or previous calendar year. Gross sales generally include taxable and (in many states) exempt sales; rules on marketplace-facilitated sales vary. Verify the specifics with the Massachusetts department of revenue.

Do marketplaces collect Massachusetts sales tax?

Massachusetts requires marketplace facilitators — platforms such as Amazon, Etsy, eBay, and Walmart — to collect and remit Massachusetts sales tax on sales made through them. If you sell only through those marketplaces, the platform generally collects the tax for you. Sales you make directly — through your own website or store — still count toward your Massachusetts economic nexus threshold and remain your responsibility. Whether marketplace-facilitated sales also count toward your own threshold varies, so confirm with the Massachusetts Department of Revenue.
