3Registered Agent Requirements
Connecticut requires all LLCs to maintain a registered agent.
Can You Be Your Own Registered Agent?
Yes, you can serve as your own registered agent in Connecticut.
Requirements: Must be an individual or business entity with a physical street address in Connecticut (no PO Boxes). Must be available during normal business hours to receive service of process and official state correspondence.
4Foreign LLC Registration
If your LLC was formed in another state but you want to do business in Connecticut, you'll need to register as a foreign LLC.
Foreign LLC Registration
- Registration Fee: $120
- Requirements: Foreign Registration Statement (LLC - Foreign) filed with the CT SOTS ($120), a certificate of existence (legal existence/good standing) from the home state delivered with the registration, and designation of a Connecticut registered agent with a physical Connecticut address. (The 90-day figure is the grace period to register and avoid the $300/month penalty, not a recency window on the certificate.)
5Connecticut LLC Taxes
Connecticut has no franchise tax or separate LLC-level tax. LLC income passes through to members who pay Connecticut individual income tax at graduated rates from 2.00% to 6.99% (bottom rate cut from 3% to 2% effective Jan 1, 2024). LLCs with employees must register with the CT Department of Revenue Services for withholding tax and may need to collect and remit sales tax at the state rate of 6.35%.
6Penalties for Non-Compliance
Late Filing Penalties
No official CT.gov source confirms a fixed monetary late fee for a late LLC annual report; non-filing instead risks administrative dissolution. Confirm current status at business.ct.gov.
Administrative Dissolution Risk
Connecticut may administratively dissolve your LLC for failure to file the annual report. A dissolved LLC loses its legal authority to transact business in Connecticut. Reinstatement uses the 'Combined Certificate of Reinstatement and Annual Report' and payment of overdue annual report fees.

Connecticut LLC: Frequently Asked Questions
How much is the Connecticut LLC annual report fee in 2026?
The Connecticut LLC annual report fee is $80 in 2026, paid to the Connecticut Secretary of the State (SOTS). Corporations pay $150. The fee is unchanged from prior years and must be paid online at business.ct.gov when filing the annual report.
When is the Connecticut LLC annual report due?
The Connecticut LLC annual report is due by the last day of the anniversary month of your LLC formation. For example, an LLC formed on March 12 must file by March 31 each year. Reports may be filed as early as January 1 of the due-date year.
What is the late fee for a Connecticut LLC annual report?
Connecticut charges a $50 late fee for missed annual reports on top of the $80 filing fee. Continued failure to file can lead to administrative dissolution, after which reinstatement costs $50 plus all overdue annual report fees.
How do I file a Connecticut LLC annual report online?
File online at business.ct.gov: (1) log in to your CT SOTS business account, (2) search for your LLC by name or business ID, (3) confirm or update the principal office, mailing address, member/manager details, and registered agent, (4) pay the $80 filing fee by credit card or ACH, (5) download the filing confirmation for your records. Processing is instant when filed online.
What happens if I do not file the Connecticut LLC annual report?
Missing the deadline triggers a $50 late fee. If you continue to miss filings, the CT SOTS may administratively dissolve your LLC, meaning it loses legal authority to do business in Connecticut. Contracts entered while dissolved can be voidable. Reinstatement requires filing a Certificate of Reinstatement, paying $50, and clearing all overdue annual report fees.
