The recurring filing: Annual Report
One recurring filing keeps a Connecticut LLC active. The particulars:
- Filing: Annual Report
- Filed with: Connecticut Secretary of the State, Business Services Division
- Fee: $80, every year[3]
- Deadline: On or before March 31[2]
- How to file: online
Connecticut sets the $80 fee; no separate late fee is recorded for it. Missing it puts the company out of good standing in Connecticut until the filing is made.
Service costs on top of state fees
Every Connecticut LLC has to keep a registered agent on record. Serving personally is open to any owner who lives in Connecticut and has a qualifying address. The company itself cannot be its own registered agent.
Agent-only service from Mainstay Filing costs $149 a year in Connecticut[1]. For $199 a year it also forms the company, applies for the EIN and files the Annual Report when due. Neither price rises at renewal.
We also read 6 other services' Connecticut prices on October 20, 2026. First-year prices ran $99 to $249; renewals ran $125 to $249.
