Do you need to collect sales tax in Massachusetts?
You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales over previous or current calendar year. Massachusetts used to trigger nexus at 200 transactions but removed that count in October 2019 — only the sales figure matters now.
The Massachusetts rate
Massachusetts imposes a flat statewide sales tax rate of 6.25% with no local or county sales taxes. The effective combined rate is always 6.25% regardless of location within the state.
Marketplace and direct sales
Marketplaces like Amazon collect Massachusetts tax for you, but those sales don't count toward your own threshold. Direct sales on your own store you collect yourself.
Filing and zero returns
Once registered, Massachusetts requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Filing frequency assigned by MA DOR based on tax collected: monthly if $1,201 or more collected (due 20th of following month); quarterly if $101–$1,200 collected (due 20th of month following quarter end); annual if $100 or less collected (due January 20).
When you can cancel
If your Massachusetts returns are mostly $0, you may be over-registered. Canceling your Massachusetts sales tax registration makes sense once you are certain you have dropped below the $100,000 gross sales threshold in both the current and prior calendar year and no longer have physical nexus in the state. The key catch is that Massachusetts uses a prior-or-current-year measurement period, meaning you likely owe filings through at least the remainder of the current calendar year even after sales drop off — and many practitioners treat Massachusetts as a calendar-year-trailing state requiring compliance into the following year as well.
