How to Qualify as a Foreign Business in Connecticut

Learn the rules for qualifying your LLC to do business in Connecticut.



If you own a business that was created in a state other than Connecticut, you will need to qualify or register that business in Connecticut if you want to do business there. Here is an overview of the rules on how to qualify your foreign (non-Connecticut) limited liability company (LLC) to do business in Connecticut.

What is a Foreign LLC?

For Connecticut purposes, if your LLC is formed in another state, then it is known as a foreign LLC in Connecticut. In other words, foreign doesn’t mean from another country. Instead, it means your business was organized under the laws of another state. A domestic LLC, on the other hand, is one that is formed in the state where it is doing business. This is common usage throughout the United States. For example, an LLC formed in Arizona is a foreign LLC in Colorado.

Transacting Business in Connecticut

According to Connecticut’s LLC Act, you are required to register your foreign company with the state of Connecticut if you are “transacting business” in Connecticut. What does this mean? Well, like most states, Connecticut’s LLC Act does not specifically define the phrase “transacting business” in relation to foreign registrations.

However, state laws governing when foreign companies must collect state sales tax in their state provide some guidance on the issue. Under these laws, a business must have a physical presence in—or nexus with—the state in order to be required to collect state sales tax on sales to that state’s residents. Generally speaking, physical presence and nexus are synonymous, and mean having:

  • a warehouse in the state
  • a store in the state
  • an office in the state, or
  • a sales representative in the state.

Certain exceptions may apply and the rules can get more complicated with things like Internet sales. Nevertheless, in general, if you have an office, a store, a warehouse, or employees in another state, you will need to qualify your LLC as a foreign company in that state. For more details, including some possible distinctions between physical presence and nexus, check Nolo’s articles on  Internet Sales Tax: A 50-State Guide to State Laws.

Certain Activities Are Exempt

Like most states, Connecticut’s LLC Act specifies certain activities that do not constitute transacting business in the state. The items listed include:

  • defending or settling a lawsuit
  • dealing with internal LLC affairs such as holding member meetings
  • having a bank account in the state
  • having an office, agency, or persons in the state for handling your company’s own securities
  • selling through independent contractors
  • soliciting or obtaining orders where the orders require acceptance outside the state before they become contracts
  • creating or acquiring indebtedness, mortgages, or security interests in real or personal property
  • securing or collecting debts
  • voting securities or other equity ownership interests owned by your LLC
  • conducting an isolated transaction that is completed within thirty days and is not one in the course of similar, repeated transactions; and
  • transacting business in interstate commerce.

In addition, the LLC Act indicates that the latter list is not exhaustive; other activities also may be exempt. Moreover, in some circumstances, if your LLC purchases, holds, mortgages, leases, sells, or conveys real or personal property, that, too, is not considered transacting business under the LLC Act. Still further, under the LLC Act, a foreign LLC that has an ownership interest in another business that transacts business in Connecticut, without more, is not considered to be transacting business in the state. For the full, legal description of all of these exempt activities, check  Section 34-235  of the Connecticut General Statutes.

If your LLC’s only activity in Connecticut is one or more of these activities, you should not need to register with the state.

Application for Registration

To register your business in Connecticut, you must file an  Application for Registration Limited Liability Company—Foreign  with the  Connecticut Secretary of State  (SOS). You can download a copy of the application form from the SOS website.

To complete the application, you must provide more or less the same information that you need to create an LLC in your home state. More specifically, for a Connecticut application for registration, you need to provide:

  • the name of your LLC in the state where it was formed
  • the name under which your LLC will transact business in Connecticut (you will need a different name for Connecticut if your LLC’s original name is already being used by a Connecticut registered business or the original name does not comply with Connecticut’s LLC naming rules)
  • the state where your LLC was formed
  • the date on which your LLC was formed
  • the date on which your LLC began or will begin transacting business in Connecticut
  • the street address of the office your LLC is required to maintain in its home state, if it is so required
  • if there is no office required in your LLC’s home state, the street address of your LLC’s principal office
  • a description of the business the LLC will transact in Connecticut
  • the name and street address of your LLC’s  registered agent  in Connecticut including the agent’s signature accepting appointment, or a statement that your LLC appoints the Connecticut Secretary of State as its registered agent in Connecticut
  • the name and address of one member or  manager  of your LLC
  • an email address for your LLC, and
  • an authorized signature.

You may submit the application by mail or in person. The filing fee is $120.

What Happens if You Don’t Register?

If your LLC transacts business in Connecticut without being registered, it cannot bring a lawsuit in any of the state’s courts. In addition, your LLC will be liable for all fees and taxes it should have paid if properly registered, as well as all interest and penalties imposed for the failure to pay. Furthermore, an LLC is liable for an additional penalty $300 per month for each month it should have been registered but was not, and may be blocked by the state from transacting further business in Connecticut until all penalties and fines have been paid.

However, not being registered does not invalidate your LLC’s contracts or prevent it from defending a lawsuit in Connecticut. Also, a member of the LLC is not liable for the LLC’s debts and obligations solely because the company transacted business in Connecticut without a certificate of registration.

Registering a Foreign Corporation in Connecticut

If your business is organized as a corporation rather than an LLC, the rules and requirements for foreign qualification in Connecticut are similar. You will, however, have to use a different application form (Form CFAS-1-1.0). See the  Connecticut Secretary of State  website for forms, information, and filing instructions for registering a foreign corporation in Connecticut.
