Connecticut Annual Report: Online Filing, Deadlines and Fees

Connecticut uses the annual report to keep company records current and publicly accessible. Every registered entity files once a year, although the timing is different for corporations compared with LLCs and partnerships. All filings are completed online through the state portal, which standardizes the process and provides immediate confirmation

How Connecticut’s
system works
The state directs all entities to Business.CT.gov for annual reports. Corporations follow an anniversary-based schedule that tracks the date of incorporation or authorization. LLCs and partnership entities use a single filing window that opens on January 1st and closes on March 31st. This split creates predictable workloads for both businesses and the state while keeping public records reliable.
Key features
• Online filing only through Business.CT.gov
• Entity specific deadlines and fee structures
• Anniversary-based due dates for corporations
• January 1st to March 31st window for LLCs and partnerships
• Enforcement that can lead to administrative dissolution if filings are missed
Who must file and
what it costs
All entities registered in Connecticut submit an annual report. The fee depends on structure and, for corporations, on whether the company is stock or non stock.
Corporations
  • Stock corporations: $150.00 due on the anniversary date
  • Non stock corporations: $50.00 due on the anniversary date
  • Professional corporations: Follow the stock or non stock fee as applicable
  • Foreign corporations: Same fees as domestic corporation
Limited liability companies
  • Domestic LLCs: $80.00
  • Foreign LLCs: $80.00
  • Professional LLCs: $80.00
  • Series LLCs: Each series may require a separate filing
Partnership entities
  • Limited liability partnerships (LLP): $80.00
  • Limited partnerships (LP): $80.00
  • Foreign partnerships: Same fees as domestic entities
Deadlines and filing windows
Connecticut uses two timing models so entities can plan ahead with certainty.
• Corporations: File on the anniversary date of incorporation or authorization
• LLCs and partnerships: File any time from January 1st through March 31st
• Late filing triggers penalties, and extended non compliance can result in dissolution
Filing early within your window reduces the risk of payment issues or last day bottlenecks.
Information you will need
Gather the following before you start so the online form can be completed in one session.
• Legal entity name and Connecticut registration number

Penalties, dissolution and reinstatement
Connecticut applies penalties immediately after a missed deadline. Ongoing non compliance can lead to administrative dissolution or revocation of authority for foreign entities. To restore status, you must file all delinquent reports, pay outstanding fees and penalties, and complete the reinstatement steps inside Business.CT.gov. Additional processing time and costs can apply, so filing on time is the most efficient path.
Why this structure helps businesses
A single statewide portal reduces guesswork, and the split between anniversary filings and a fixed January through March window allows teams to schedule compliance work without disrupting operations. The system provides immediate confirmations, clear fee schedules, and access to customer support when questions arise.
