Connecticut Corporation FAQ — Common Questions Answered

What document creates a Connecticut corporation?

The Certificate of Incorporation, filed with the Connecticut Secretary of the State through the Business One Stop portal. It is Connecticut's version of what many states call the Articles of Incorporation. It lists the corporate name, authorized shares, registered agent and registered office, and incorporator. Once the state processes it, the corporation legally exists.

Do I have to live in Connecticut to form a corporation here?

No. Shareholders, directors, officers, and the incorporator face no residency requirement, so your own home state is irrelevant to forming a corporation here. The only in-state requirement is a registered agent with a physical Connecticut street address.

How long does incorporation take?

Online filings are generally processed within a couple of business days, depending on the Business Services Division's current workload. The corporation is active and searchable once the Certificate is processed.

Can one person form a corporation?

Yes. A single individual can be the sole shareholder, the only director, and hold every officer role. Connecticut permits a single-director board. You just have to respect the structure — the shareholder elects the director, the director appoints the officers, and the decisions get documented.

What are the naming rules?

The name must include a corporate designator — "Corporation," "Incorporated," "Company," or an abbreviation like "Corp.," "Inc.," or "Co." — and it must be distinguishable from every other business name already on file in Connecticut. Certain restricted words tied to regulated industries may require approval before use.

How do I check if a name is available?

Use the Connecticut business records search. Search your proposed name and close variations. If something too similar is registered, the state can reject your Certificate, so it pays to check before filing.

Can I reserve a name before filing?

Yes. Connecticut lets you reserve an available name for a limited period through the Business One Stop while you get everything else ready. A reservation holds the name but does not form the corporation.

Can I operate under a different name?

Yes, by registering a trade name (also called a fictitious or assumed name). In Connecticut, trade names are filed with the town clerk in the town where you do business — not with the Secretary of the State. It's a separate step from incorporating.

Does my corporation need a registered agent?

Yes. Every Connecticut corporation must appoint and continuously maintain a registered agent with a physical Connecticut street address. The agent receives lawsuits and official state mail. You can serve yourself, name another eligible person, or hire a commercial service.

What is the annual report?

Connecticut requires every corporation to file an annual report confirming its registered agent, principal office, and officers and directors. The report must be filed online — Connecticut does not accept paper annual reports. It is a compliance filing, not a financial statement.

What happens if I miss the annual report?

Falling behind on the annual report eventually pushes the corporation out of good standing. That can block financing, contracts, and expansion into other states. Reinstating a lapsed corporation is more work and more cost than just filing on time, so it pays to track the deadline.

Can I change my registered agent later?

Yes, anytime, by filing a change of agent through the Business One Stop portal. Corporations commonly do this when switching to a commercial service or when an individual agent moves or steps down.

How is a Connecticut corporation taxed?

By default it's a C corporation: it files its own federal return and pays Connecticut's corporation business tax at the entity level, and shareholders are taxed again on dividends. You can elect S corporation status with the IRS to make federal income pass through to shareholders instead. Connecticut recognizes the federal S election.

Does my corporation need an EIN?

Yes. A corporation is a separate taxpayer and can't use an owner's Social Security number, so it needs its own EIN from the IRS. You'll need it to file the corporate return, open a bank account, run payroll, and make an S election. Applying online is free and immediate.

Do I need a separate bank account?

Yes — it's essential to the liability shield. Run all corporate money through a dedicated business account. Mixing personal and business funds is one of the fastest ways to give a court a reason to pierce the corporate veil and reach your personal assets.

Do I need any licenses?

Connecticut doesn't issue a single general business license, but many industries and professions require state or local licensing, and some municipalities have their own requirements. These are separate from incorporation and run on their own cycles.

How do I close a Connecticut corporation?

You dissolve it formally. Typically the shareholders and directors approve dissolution, you wind up the business (pay debts, distribute remaining assets), close out tax accounts, and file a Certificate of Dissolution with the Secretary of the State. Simply walking away leaves the corporation on the books, still accruing compliance obligations.

My corporation was formed in another state — do I register in Connecticut?

If you are transacting business in Connecticut, yes. You foreign-qualify by applying for a Certificate of Authority and appointing a Connecticut registered agent. Operating without qualifying can bar you from Connecticut courts and lead to back fees.

Can I change my corporation's information after formation?

Yes. Changes to the corporate name, authorized shares, or other Certificate items are made by filing an amendment; changes to your agent are a change-of-agent filing; and each year's annual report updates your officer, director, and address information. All of it runs through the Business One Stop portal.
