What is different about forming an LLC in Connecticut.
Every state runs its own filing office, its own fee schedule and its own ongoing obligations. These are the ones that apply in Connecticut.
| Item | Amount | Detail |
|---|---|---|
| LLC filing fee | $120 | Paid to the state, at cost. File.Business charges $0 to prepare and file it. |
| Corporation, for comparison | $250 | |
| Nonprofit | $50 | |
| Professional LLC (PLLC) | $120 | |
| Series LLC | Not offered | Connecticut has no Series LLC filing. |
| Ongoing state report for an LLC | $80 | Annual Report, annual, due LLCs file each year between January 1 and March 31. Stock corporations, nonstock corporations, LPs and LLPs file by the last day of the anniversary month of formation or registration and may file up to one month early. |
| Registering an out-of-state LLC here | $120 | A certificate of good standing from your home state is required. Filed on the Foreign Registration Statement. |
What the Connecticut fee schedule actually says
The domestic stock corporation annual report is 150. The 435 figure that is widely misquoted as the Connecticut corporation rate is the FOREIGN stock corporation annual report, and it applies to no domestic entity. Nonstock corporations pay 50 whether domestic or foreign, and LLCs, LPs and LLPs pay 80 whether domestic or foreign. Connecticut stock corporations also file a one time Organization and First Report at 150 after the organisation meeting, which is separate from the annual report.

What forming an LLC in Connecticut actually involves.
Articles of Organization
The Articles of Organization is the founding Connecticut document. We prepare and file with the SOS using your entity name, organizer info, RA, and member structure.
~5 day Connecticut processing
Connecticut SOS typically processes standard LLC filings in 5 business days. Expedited options available for an extra state fee (varies $25-$200).
Registered Agent included
Connecticut requires every LLC to maintain a Registered Agent. RA service is included year one in every formation bundle.
EIN from the IRS
Your Connecticut LLC needs a federal EIN for banking, taxes, and payroll. We file Form SS-4 with the IRS, typically 1-2 business days, faster than DIY filings.
Operating Agreement
Connecticut doesn't require filing an Operating Agreement with the SOS, but every Connecticut LLC needs one to define member rights, voting, profit splits, and dissolution rules. Included in Domestic Complete.
Year-one compliance
Forming the LLC is step one. Connecticut requires ongoing compliance: Annual Report (Mar 31), state tax registrations, license renewals. Domestic Complete includes year-one AR AutoFile.
A clean handoff, in 6 steps.
Pick your Connecticut LLC name
We check Connecticut SOS name availability live. Your chosen name must include "LLC" or variant and not conflict with existing Connecticut registrations.
Designate Registered Agent
Every Connecticut LLC needs a RA with a physical Connecticut address. We provide one (included year one) or you can designate your own.
Prepare Articles of Organization
Member info, RA, principal office, management structure (member-managed vs manager-managed), effective date. We draft and review with you.

Common questions.
Do I need to live in Connecticut to form an LLC there?
No. You do not need to live in Connecticut or be a resident to form an LLC there. What Connecticut requires is a registered agent with a physical in-state address to receive legal mail, which we provide, or you can act as your own if you have a Connecticut address and are available in business hours. Where you live does not limit where you can form.
What is the difference between an LLC and a corporation in Connecticut?
An LLC is simpler and pass-through: profit lands on your personal return and there is little required formality, which suits most owners in Connecticut. A corporation is built to raise venture capital and issue stock, but it adds bylaws, a board, and annual meetings. If you plan to raise money, look at forming a corporation; otherwise the LLC-versus-corporation comparison lays out the tradeoffs.
Does Connecticut require an Operating Agreement?
Connecticut may not require you to file one, but you should have one. The Operating Agreement sets who owns what, who can sign, and what happens if an owner leaves, and it is the document that shows the LLC is a genuine separate entity, which protects your liability shield. Banks and lenders also ask for it. Generate one that fits your ownership with our Operating Agreement tool.
What about the EIN for my Connecticut LLC?
The EIN is your business's federal tax ID, and you need it to open a bank account, hire, or file taxes. It is free from the IRS, and we obtain it for you the same day, including for founders without a Social Security Number. Keeping the EIN separate from your SSN also keeps your personal number off vendor and client paperwork. Start with our EIN guide.
Can a foreign person form a Connecticut LLC?
Yes. You do not need to be a US citizen or resident to own or form a Connecticut LLC, and you never have to set foot in the state. The one extra step is the EIN, which we obtain from the IRS for you when you have no Social Security Number, and that unlocks US banking and payment processing. Our EIN guide is the right starting point for international founders.
What ongoing compliance does a Connecticut LLC require?
Forming is the start, not the finish. A Connecticut LLC generally files a periodic annual report, keeps a registered agent on record, and pays any state franchise tax. Miss the report and Connecticut can administratively dissolve the LLC, ending the protection you formed it for. A compliance calendar keeps every date in view, and our subscription can file them for you.
Can I change my Connecticut LLC name later?
Yes. If you outgrow the name or rebrand, you change it by filing Articles of Amendment with Connecticut, which updates the official record; your EIN and entity stay the same. If you would rather keep the legal name and operate under a different public name, a DBA does that without a full amendment. We handle either the amendment or the DBA for you.
