Massachusetts foreign registration service pricing in 2026: first year, renewals, three-year total
Every price comes from the company's own pages as of November 12, 2026. The $500 Massachusetts registration fee comes on top of each row and is left out of the totals.
Why these made the shortlist
On Filing Shortlist's shortlist, three-year price and what the price covers carry 28% each and renewal terms, fit for the state and price clarity share the other 44%. In Massachusetts, what the price covers made the difference.

Registering a foreign LLC in Massachusetts: fee, form and office
Registration goes to the Massachusetts Secretary of the Commonwealth, Corporations Division on the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48). The state fee is $500. Along with the form, Massachusetts expects certificate of legal existence or good standing, no older than 90 days when you file.
Each year after that, the company files the Foreign LLC annual report for $500, due anniversary of registration.
What to have ready before you file
- Certificate of legal existence or good standing, dated within 90 days of filing.
- The company's exact legal name and its formation date in the home state.
- A resident agent at a street address in the state. Every company on this shortlist can be that agent.
- Payment of the $500 state fee with the filing.
- A reminder in your own calendar for the Foreign LLC annual report and its $500 fee.
The cost of skipping Massachusetts registration
An unregistered out-of-state LLC cannot sue in Massachusetts courts (G.L. c. 156C, 54(a)). Its contracts remain valid (G.L. c. 156C, 54(a)).
