Pick a name that is distinguishable from other businesses already on file with the Connecticut Secretary of the State and that includes a required designator such as "LLC" or "Limited Liability Company." Most states let you search name availability online before you file.
A registered agent with a physical Connecticut address is required. This is the person or company that receives legal notices and official state correspondence on the LLC's behalf.
Submit your formation document to the Connecticut Secretary of the State, either online or by mail depending on what the state offers, along with the required filing fee.
Once the Connecticut Secretary of the State processes and approves the filing, it issues an approved copy of your formation document — this is your LLC's official proof of existence.
Even in states that don't legally require one, an Operating Agreement spells out ownership percentages, management structure, and how decisions get made — and most U.S. banks will ask to see one before opening a business account.
An Employer Identification Number is a separate federal step from state formation and is generally needed to open a bank account, file taxes, and hire employees. See our EIN explained guide.
Keeping business funds separate from personal funds is central to preserving the liability protection an LLC is meant to provide. Banks typically require the approved formation document, EIN confirmation letter, and Operating Agreement.
Connecticut LLCs must file an annual report with the Secretary of the State to remain active. Missing these ongoing requirements is one of the most common ways owners accidentally lose good standing.
Paid directly to the Connecticut Secretary of the State when your Certificate of Organization is filed. States set and periodically change this amount, so we don't publish a figure here that could go stale — check the official Connecticut Secretary of the State site or contact us for current, confirmed pricing.
Free if you qualify to act as your own agent and have a physical Connecticut address. Otherwise, a professional registered agent service charges an annual fee for a reliable in-state address and mail handling.
Connecticut LLCs must file an annual report with the Secretary of the State to remain active.
An LLC formed in another state doing business in Connecticut generally must register there as a foreign LLC.
Non-U.S. residents can generally form an LLC in Connecticut using a registered-agent service and, where required, a U.S. mailing address — no Social Security Number, U.S. visa, or U.S. citizenship is needed to be an LLC owner. The two federal identifiers that matter afterward are different things: an EIN identifies the business to the IRS, while an ITIN identifies an individual for U.S. tax-filing purposes and is only needed if you personally have a U.S. tax-filing obligation. See our general guide on non-U.S. residents forming a U.S. LLC.
By default, the IRS treats a single-member LLC as a "disregarded entity" and a multi-member LLC as a partnership — meaning profits pass through to the owners' own tax returns rather than being taxed a second time at the entity level. An LLC can also elect corporate or S-corporation tax treatment where it qualifies. These federal default rules are the same regardless of which state the LLC is formed in.
Connecticut has state personal and corporate income tax, and separate filing obligations may apply depending on how the LLC elects to be taxed. To open a bank account, file taxes, or hire employees, the LLC itself will need an EIN — see EIN explained. If you personally need to file a U.S. tax return and don't have a Social Security Number, you may separately need an ITIN — see ITIN services or the full LLC vs EIN vs ITIN comparison.
All owners (members) participate directly in daily decisions and can bind the LLC in contracts. This is the more common default for small, owner-operated businesses and is often the simplest structure when there are just one or a few owners.
One or more designated managers run daily operations while non-manager members stay more passive, similar to shareholders in a corporation. This structure is common for larger LLCs, family-owned entities, or where non-U.S. owners prefer to designate a specific person to handle day-to-day matters.
Connecticut's LLC law permits either structure. Depending on the state, this choice may need to be indicated on the Certificate of Organization itself — check the Connecticut Secretary of the State's filing instructions — and it should always be documented in detail in the LLC's Operating Agreement.
Yes, filed each year with the Secretary of the State.
Yes, Connecticut has both personal and corporate state income tax.
Yes. Connecticut does not require LLC owners to be U.S. citizens or residents.
Processing times depend on the Connecticut Secretary of the State's current workload and on the filing method used — online filings are generally processed faster than filings submitted by mail. Check the Connecticut Secretary of the State's website for current processing times, or contact us and we'll give you an up-to-date estimate before you file.
In most states, an LLC owner who has a physical street address (not a P.O. box) in the formation state can act as their own registered agent. In practice, many owners — especially those living outside Connecticut or outside the United States — use a professional registered agent service instead, so official mail and legal notices are reliably received and privacy is preserved.
In a member-managed LLC, the owners (members) handle day-to-day decisions and can sign contracts on the LLC's behalf directly. In a manager-managed LLC, the members appoint one or more managers — who may or may not also be owners — to run daily operations, while non-manager members stay more passive. Most states, including Connecticut, allow either structure; some also ask you to indicate the choice on the formation filing itself, while all states let you document it in the Operating Agreement.
Possibly, in addition to LLC formation. Many cities, counties, and specific industries (such as food service, contracting, or professional services) require their own business license or permit, separate from registering the LLC with the Connecticut Secretary of the State. Requirements depend on where the business is located and what it does — we can help you identify what applies to your situation.
Missing a required report, publication step, or fee generally causes the LLC to fall out of "good standing" and, if left unresolved, can lead to administrative dissolution by the Connecticut Secretary of the State. Most states allow reinstatement within a certain window, sometimes with a late penalty attached, so it's worth acting quickly if you receive a compliance notice.
Filing rules, forms, and requirements are set by the state and can change. Confirm current requirements with the Connecticut Secretary of the State before filing. Sangemeel.LLC does not display filing fees on this page because state fees change; contact us for current, confirmed pricing.
