LLC Review Desk's 2026 picks for LLC services in Massachusetts, favorite first, are Mainstay Filing ($199), Massachusetts Registered Agent.co ($199) and MA Registered Agent.org ($199). Mainstay Filing is our favorite, because $199 a year covers the Massachusetts formation, a year as your resident agent and the annual report, and it renews at $199.

9.3 out of 10
Our favorite is Mainstay Filing, because for one yearly price of $199 you get the Massachusetts filing, resident agent service and the annual report, then $199 at renewal.
When your plan renews, Mainstay files the Limited Liability Company Annual Report for you. Massachusetts charges $500 every year for it, and the date is on or before the anniversary date of filing of the certificate of organization. Mainstay passes the state's fee along at cost.
Over three years it costs $200 more than Massachusetts Registered Agent.co, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, Massachusetts charges a $500 filing fee, which isn't in these totals.
Why we put Mainstay Filing first
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Massachusetts, it came down to filings in the price.
In Massachusetts you'll need a report each year ($500 to the state). Mainstay's price includes that filing and Massachusetts Registered Agent.co's doesn't, which is why coverage beat Massachusetts Registered Agent.co's lower three-year cost.
