Massachusetts: Foreign LLC Registration and Qualification Requirements

Requirements one by one

Governing law, trigger, and complete statutory lists

G.L. c. 156C, § 47 keeps the foreign formation jurisdiction's law in control of
the LLC's organization, internal affairs, and member/manager liability. The
foreign LLC cannot conduct a business that a Massachusetts LLC is prohibited
from conducting.

Section 48 imports the foreign-corporation doing-business standard from G.L.
c. 156D, § 15.01. Unlike statutes that require qualification before starting,
Massachusetts gives a foreign LLC 10 days after it commences business to
submit the registration application.

The imported standard has both positive and negative lists. It expressly says
that owning or leasing Massachusetts real estate, construction or repair of a
structure, railway, or road, and any other activity requiring the performance
of labor do constitute transacting business.

The activities that, “without more,” do not constitute transacting business
are proceedings; internal-affairs activity; bank accounts; securities-transfer
offices, trustees, and depositories; sales through independent contractors;
orders that require acceptance outside Massachusetts; an isolated transaction
outside repeated like transactions; interstate commerce; and activity regulated
under chapter 167 or 175 after compliance with that chapter. Section 15.01(d)
says both lists are nonexhaustive. The isolated-transaction provision has no
fixed duration, and the statute contains no clauses (7) or (8).

Application, signer, and home-state evidence

Under § 48 and 950 CMR 112.22, the application states the FEIN; foreign and any
different Massachusetts name; formation jurisdiction and date; business
character; principal-office address and any Massachusetts principal office;
each manager and address, or a statement that there are no managers; resident
agent; any specific dissolution date; and any optional real-property instrument
signatories. An authorized person must sign and swear to the application; the
current paper form calls for at least one authorized signatory.

The application must include a legal-existence, good-standing, or comparable
certificate from the properly authorized home-jurisdiction official. The
regulation adds a 90-day maximum age measured before submission. If that
evidence is in another language, attach a translation under oath of the
translator.

A certified copy of the home certificate of organization may replace the
application fields that it already supplies, with a sworn translation if
necessary. That substitution does not remove the separate requirement to
submit current evidence of legal existence.

Name, resident agent, filing, and effectiveness

Section 50 allows a foreign LLC to use any name a Massachusetts LLC could
assume. Under § 3, that means a permitted LLC designator and a name that is not
the same as or deceptively similar to a protected entity name unless the prior
entity's written consent has been filed.

Sections 48 and 51 require a resident agent's name, Massachusetts street
address, and written consent. Through § 51's cross-reference to G.L. c. 156D,
§ 15.07, the agent may be a Massachusetts-resident individual, a listed
domestic entity, or a listed foreign entity authorized in Massachusetts. The
agent's business office must be identical with the Massachusetts registered
office. A separate Massachusetts principal office is listed only if one exists.

950 CMR 112.09 permits electronic transmission, postal delivery,
personal/courier delivery, and authorized fax delivery. The registration fee is
$500 under § 48 and 950 CMR 112.22. Under 950 CMR 112.10, the filing is
effective on the date the Corporations Division approves it.

Consequences and cure

G.L. c. 156C, § 54 permits a fine of up to $500 for each year the foreign
LLC remains unregistered. While the failure continues, the LLC cannot maintain
an action or obtain recovery in a Massachusetts court. Registration ends that
stated court-access condition, but it does not promise to erase a fine or cure
an unrelated tax, license, limitations, or service issue.

The same section preserves contracts, permits the LLC to defend, and says a
member or manager is not liable for company obligations solely because of the
failure. An unregistered LLC is deemed to have appointed the Secretary of the
Commonwealth for service of process while the covered Massachusetts liability
remains outstanding.

What trips people up

• The 10-day rule runs after commencement. It is a short post-start filing
  window, not a blanket rule that authority must issue before the first act.
• Real-estate ownership is a positive trigger. Massachusetts does not use
  the common “owning property without more” safe harbor; § 15.01 lists owning
  or leasing Massachusetts real estate as transacting business.
• The safe-harbor list is nonexhaustive. An activity outside the list is
  not automatically a trigger, but the express positive list still matters.
• The 90-day evidence rule comes from the regulation. The statute itself
  requires current legal-existence evidence without stating that number.

Common questions

Does an isolated transaction have to finish within 30 days?

No. The statute asks whether it is isolated and outside repeated transactions
of a like nature; it states no fixed duration.

Can the home certificate of organization replace the application?

Only in part. A certified copy may supply matching application information, but
the filing still needs the current certificate of legal existence or good
standing required by § 48 and 950 CMR 112.22.

Can an unregistered LLC defend a Massachusetts lawsuit?

Yes. Section 54 preserves defense rights and contract validity. The court bar
applies to maintaining the LLC's own action or obtaining recovery while the
failure continues.
