To form a Connecticut LLC, you file a certificate of organization with Connecticut Business Services, and the fee is $120, including the appointment of your statutory agent, as of October 2026. After that, the LLC files an $80 annual report online between January 1 and March 31 each year.
Connecticut keeps its LLC paperwork fairly lean, but the fees and the timing are easy to get wrong if you're used to another state. The certificate of organization covers the agent appointment in the same filing, the annual report has a fixed window, and there's a sharp penalty for out of state companies that trade without registering. Here's what the state's fee page and the statute say.
Connecticut LLC fees from Connecticut Business Services
These are the domestic LLC lines from the state's forms and fees page, as of October 2026:
| Filing | Fee |
|---|---|
| Certificate of Organization, including appointment of statutory agent | $120 |
| Annual Report, filed online from January 1 to March 31 | $80 |
| Application for Reservation of Name | $60 |
| Certificate of Amendment | $120 |
| Interim Notice of Change of Manager or Member | $20 |

The statute behind the table, in Chapter 613a of the Connecticut General Statutes, also sets a certificate of reinstatement at one hundred twenty dollars and a foreign registration certificate at the same amount, and an amended annual report at twenty five dollars.
The annual report window, and why it matters
Connecticut's annual report isn't tied to the date you formed. The state's fee page says it's filed online annually from January 1 to March 31, for $80. That makes it easy to diary: one reminder at the start of each year covers every Connecticut LLC you own.
If your managers or members change part way through the year, there's a separate interim notice for $20, so you don't have to wait for the next annual report to put the record straight. And if you spot a mistake in a report after you've filed it, the statute provides for an amended annual report. Our guide to the LLC annual report compares how other states handle the same job.
How to form a Connecticut LLC
- Search the name with Connecticut Business Services. If you need to hold it while you prepare, a name reservation is $60.
- Choose your statutory agent. The appointment is part of the certificate of organization, so you'll need their details before you file. A registered agent service is an option if you don't want your own address used.
- File the certificate of organization online and pay $120.
- Write an operating agreement setting out who owns what and how decisions are made.
- Register with the Department of Revenue Services for the taxes your business will collect or pay.
- Diary January 1 to March 31 for every annual report from then on.
The penalty for a foreign LLC trading in Connecticut
If your LLC was formed in another state, Connecticut's statute is strict about registering before you trade. A foreign LLC that transacts business in Connecticut without a valid foreign registration certificate is liable for three hundred dollars for each month, or part of a month, it traded unregistered. There's one escape: a company that registers with the Secretary of the State no later than ninety days after it starts trading here isn't liable for the monthly penalty.
So if you're expanding into Connecticut, register within that ninety day window. It costs one hundred twenty dollars under the statute, which is far less than even a single month of the penalty. If you're weighing a new Connecticut company against registering your existing one, our foreign LLC guide sets out the trade-offs.
Changing or closing a Connecticut LLC
Most changes have their own line on the fee table. Amending the certificate is $120, changing the agent's address or the business address is $50, and a statement of correction is $100. Closing the company with a certificate of dissolution is $0. Just remember that a closed company still needs to settle its tax accounts with the state.

Connecticut LLC costs at a glance
For a typical single-state LLC, the predictable state costs are short. You'll pay $120 to file the certificate of organization, which already includes appointing your statutory agent, so there's no separate agent filing on day one. If you reserve the name first, add $60. Then each year it's $80 for the annual report, filed between January 1 and March 31. Everything else on the fee table only applies when something changes, such as a new address, a new manager or a correction.
That makes Connecticut easy to budget for, as long as you remember two things: the annual report window is fixed, and an out of state LLC that trades here needs its foreign registration within ninety days. If you're comparing it with other states, our how to start an LLC guide covers the general steps.
Connecticut LLC mistakes to avoid
- Missing the March 31 cut-off for the annual report.
- Waiting for the annual report to record a new manager or member, when the $20 interim notice does it straight away.
- Trading in Connecticut through an out of state LLC for more than ninety days without registering.
- Filing an amendment when a statement of correction is what's needed, or the other way round.
