Below: every step, the itemized fees, and what we handle if you'd rather not DIY.
Build Your Connecticut LLC — $199
We prepare the Certificate of Organization and file it with the Connecticut Secretary of the State for $199. Online submissions are the state's preferred channel and the fastest to clear.
What A Connecticut LLC Is (and Why People Form One)
LLCs are the workhorse small-business entity — they shield the owner's personal assets and pass income straight to the owner's tax return. Among Connecticut small companies, the LLC is the small-business entity of choice because it offers liability protection paired with simple tax filing.
The $120 Connecticut LLC Filing Fee, Itemized
| Item | Fee |
|---|---|
| Our LLC formation service | $199 one-time |
| State filing fee, Certificate of Organization | $120 one-time |
| Registered agent (mandatory for every Connecticut LLC) | $99/year |
| Annual report, filed January 1 to March 31 | $80/year |
The $120 comes straight from statute: Conn. Gen. Stat. § 34-243u(a)(3) prices "filing a certificate of organization, including appointment of registered agent" at one hundred twenty dollars. $199 pays for our filing service only; RA service is $99/year, standalone.
Certificate of Organization: Connecticut's Formation Filing
Other states call this document the Articles of Organization. Connecticut calls it the Certificate of Organization (Limited Liability Company: Domestic), and the current official form is unnumbered. The statutory authority is Conn. Gen. Stat. § 34-247: "One or more persons may act as organizers to form a limited liability company by delivering to the Secretary of the State for filing a certificate of organization." (The office is formally the "Secretary of the State," an article Connecticut itself insists on.)
Two filing channels exist. Online, through the CT Business One Stop, which the state prefers and which clears fastest. Or by mail, using the unnumbered fillable PDF posted on the state's official LLC forms and fees page. Processing time varies with state workload.
How to Form Your Connecticut LLC, Step by Step
- Clear the name. The name needs an LLC suffix and clear separation from anything already on file. Check availability through the state's records search first; a rejected filing means redoing the paperwork. Restricted words include 'bank,' 'insurance,' 'trust,' and anything suggesting a government agency.
- Designate the registered agent. Conn. Gen. Stat. § 34-243n requires an agent with a place of business in Connecticut, reachable through the business day, and the appointee must sign an acceptance. Our $99/year plan covers the role and keeps your address off the record.
- Deliver the Certificate of Organization with the $120 fee. File online at business.ct.gov or mail the paper form. The filing carries the LLC name, the principal office, the agent's name, address, and acceptance, the manager- or member-managed designation, and organizer signatures.
- Draft the operating agreement. Not filed with the state, but essential internally: ownership percentages, distributions, management authority, voting rules, exit procedures. Absent an agreement, Connecticut's statutory defaults control, and they are not designed for your specific business.
- Obtain the EIN. Free from the IRS in roughly ten minutes online. Banks, payroll services, and federal filings all reference it. Paying a third party for an EIN is money wasted.
- Run the compliance calendar. Continuous registered agent coverage, the $80 annual report filed online during each January 1 to March 31 window, a clean split between the LLC's accounts and your personal accounts, and on-time tax filings. More than one year in default on the annual report exposes the LLC to administrative dissolution, at which point the liability shield is gone until you reinstate.

The Registered Agent Requirement
There's no way around the agent requirement in Connecticut; each LLC, regardless of size, needs one. The statute's operative phrase is that the agent "shall have a place of business in this state." Specifications:
- A street address in Connecticut on file (a PO box alone isn't enough)
- Availability through normal business hours for service of process
- Prompt handling of state mail and lawsuits to keep response windows intact
Using your home address as the agent address makes it part of the state record, findable through any Connecticut entity search. Our agent service in Connecticut is $99 a year; list our information on the filing and your personal address never sees the public record.
