LLC Formation Cost in Connecticut (2026)

Forming an LLC in Connecticut requires a $120 state filing fee (Articles of Organization). Add $125/year for a registered agent service and $$80/year for the annual report — total first-year cost is approximately $325. Important additional cost: Business entity tax $250 every 2 years.

If you conduct business primarily in Connecticut, form your LLC here. Forming in another state (Wyoming, Delaware, New Mexico) and then operating in Connecticut requires paying foreign registration fees in Connecticut anyway — you end up paying both states' fees. Wyoming or New Mexico make sense only if you genuinely have no state-specific business presence and want lower costs or more privacy.

Yes — Connecticut law requires every LLC to maintain a registered agent with a physical street address in Connecticut during normal business hours. You can serve as your own registered agent if you have a Connecticut address, but most business owners use a professional service ($50–$300/year) for privacy (your name and address are kept off public records) and reliability (someone is always available during business hours).

Annual Connecticut LLC costs: Annual report fee: $80. Registered agent: $50–$300/year. Special costs: Business entity tax $250 every 2 years. Add bookkeeping/accounting ($100–$500/month) and business insurance ($500–$2,000/year) for a realistic total operating cost.
