We took each price from the company's own pages on November 12, 2026. On top of every row, Massachusetts charges a $500 registration fee, which isn't in these totals.
Why we ordered them this way
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Massachusetts, filings in the price made the difference.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over MA Registered Agent.org.

Registering a foreign LLC in Massachusetts: fee, form and who to send it to
You register through the Massachusetts Secretary of the Commonwealth, Corporations Division, using the Foreign Limited Liability Company Application for Registration (General Laws Chapter 156C, Section 48). The state charges $500. Massachusetts also wants certificate of legal existence or good standing that is no more than 90 days old.
After that, plan on the Foreign LLC annual report each cycle ($500) by anniversary of registration.

Until it registers, an out-of-state LLC can't sue in Massachusetts courts (G.L. c. 156C, 54(a)). Its contracts still stand (G.L. c. 156C, 54(a)).
