How much does it cost to start an LLC in Connecticut?

The Certificate of Organization costs $120, a fee fixed by Conn. Gen. Stat. § 34-243u(a)(3) that includes appointment of your registered agent. The same $120 applies online or on paper. Optional 24-hour expedited service adds $50 per transaction and is available only for online filings.

How much is the Connecticut LLC annual report fee?

$80 per year for both domestic LLCs and registered foreign LLCs, filed after January 1 and before April 1 each year — effectively a March 31 deadline. The fee was only $20 for report years before July 1, 2020, so older cost guides are out of date. Connecticut charges no separate late fee.

When is my first Connecticut LLC annual report due?

Conn. Gen. Stat. § 34-247k(c) says the first annual report is due after January 1 and before April 1 of the year following the calendar year in which the LLC was formed. An LLC organised at any point in 2026 files its first $80 report in the January 1 – March 31, 2027 window; nothing is owed in the formation year itself.

Does Connecticut still have a business entity tax for LLCs?

No. The Department of Revenue Services states that "the Business Entity Tax (BET) no longer exists" and that Public Act 19-117 ended it for any tax period beginning after 12/31/2018. The old $250 biennial charge is gone, so the $80 annual report is the only recurring state charge for most Connecticut LLCs.

What you actually pay in Connecticut

Connecticut's $120 Certificate of Organization is statutory (Conn. Gen. Stat. § 34-243u(a)(3)), so paper and online filings cost the same. The recurring cost is the $80 annual report, which by statute must be delivered "by electronic transmission" — paper filing requires a specific exemption from the Secretary of the State. That fee was only $20 for report years before July 1, 2020. The old $250 biennial Business Entity Tax was ended by Public Act 19-117 for tax periods beginning after 12/31/2018, so there is no separate Connecticut entity-level tax today. Expedited 24-hour service costs $50 per transaction and works only on online filings.

Conn. Gen. Stat. § 34-243u(a)(3) sets a single statutory fee of "one hundred twenty dollars" for "filing a certificate of organization, including appointment of registered agent" — identical online or on paper.

No publication or newspaper-notice fee appears in Conn. Gen. Stat. § 34-243u or on the Secretary of the State's fee schedule.

Registered agent is listed separately because it is a commercial service, not a state charge. Commercial registered-agent services, not a state charge.

Connecticut LLC cost over five years

State charges only in the first column; the second adds a registered-agent service at the $125/yr market midpoint.

First filing timing: "The first annual report must be filed with the Secretary of the State after January first and before April first of the year following the calendar year in which the limited liability company was formed" (Conn. Gen. Stat. § 34-247k(c)) — an LLC formed at any point in 2026 files its first $80 report in the January 1 – March 31, 2027 window.

Is Connecticut expensive compared with other states?

Connecticut ranks 28th cheapest of 50 states on first-year cost — $34.53 below the $234.53 national average. On ongoing annual cost it ranks 36th.

Cheaper state	First-year cost	You would save
Montana	$35	$165
Arizona	$50	$150
Missouri	$50	$150

A cheaper filing fee elsewhere rarely saves money if you live and operate in Connecticut. Doing business here with an out-of-state LLC generally means registering it as a foreign LLC in Connecticut anyway — paying both states. See foreign qualification in Connecticut before forming elsewhere to save on fees.

Connecticut filing deadline and late penalties

Annual Report

Frequency	every year
Due	"after January first and before April first" of each calendar year (i.e. by March 31)
Fee	$80

Neither Conn. Gen. Stat. § 34-243u nor the Secretary of the State's fee schedule provides any late fee or penalty for a late LLC annual report; the fee stays $80 whenever it is filed. The consequence of non-filing is forfeiture, not a fee.

Under Conn. Gen. Stat. § 34-267g, once an LLC is "more than one year in default of filing its annual report" the Secretary may send electronic notice that the company's rights and powers are prima facie forfeited; if the report is not filed "within three months of the sending of such notice" the Secretary files a certificate of dissolution by forfeiture. Reinstatement then costs $120.

Cost traps specific to Connecticut

$80 annual report is one of the pricier in the region

Connecticut charges $80 per year for an LLC annual report — four times the $20 it charged for report years before July 1, 2020 (Conn. Gen. Stat. § 34-243u(a)(15)) — and the full amount is due even if nothing about the company changed.

Annual report must be filed electronically

Conn. Gen. Stat. § 34-247k(a) requires the report to be delivered "by electronic transmission"; paper filing is only allowed if the Secretary of the State grants an exemption for lack of capability or other good cause.

Forfeiture after one year in default

Under § 34-267g, once you are more than one year in default the Secretary can send a forfeiture notice and dissolve the LLC three months later. Getting it back costs a $120 Certificate of Reinstatement plus the missed $80 reports.

Where these numbers come from

Every fee above was checked against Connecticut's own published sources on July 29, 2026 — the Connecticut Secretary of State fee schedule, the governing statute, and where a state-level tax applies, the state tax authority. Commercial formation-service pages were not used.

The first-year total is the Certificate of Organization fee plus the first year of any recurring state charge. Where a state's first report is not due until the following year, that is noted above. The five-year total is the filing fee plus five years of recurring charges, which avoids the timing question entirely. Registered-agent service is excluded from all state figures.
