Connecticut annual reports, deadlines, and fees
Start with your entity type below. Connecticut reporting schedules can differ for LLCs and corporations; a report may be annual, biennial, or not required for a particular entity type.
Open Connecticut filing agency ↗Connecticut LLC reports
Connecticut LLC annual reports are due each year from January 1 through March 31, beginning with the applicable filing cycle, and cost $20.00. The report includes principal and mailing addresses, email, and at least one member or manager's name/title/residence/business address; the business name and registered-agent information cannot be changed on the report. There is no additional late penalty fee listed in the official FAQ, but the Secretary may refuse a Certificate of Legal Existence and may administratively dissolve an LLC more than one year in default.
Connecticut corporation reports
Domestic stock-corporation annual reports are due by the last day of the anniversary month and cost $150.00. Domestic nonstock corporations file a $50.00 annual report. Foreign stock corporations file a $435.00 annual report; foreign nonstock corporations file a $50.00 report. A domestic corporation also files the Organization and First Report after its organizational meeting, and stock corporations separately owe the authorized-share franchise tax.
Connecticut franchise and business taxes
Connecticut imposes a franchise tax on domestic stock corporations based on authorized shares. The minimum is $150.00; the schedule charges one cent per share through the first 10,000 authorized shares, one-half cent per share from 10,001 through 100,000, one-quarter cent per share from 100,001 through 1,000,000, and one-fifth cent per share above one million. The tax is a formation/annual corporate obligation distinct from the $100.00 Certificate of Incorporation and $150.00 annual report. LLCs do not use this stock-share franchise-tax calculation.
A registry report and a tax filing can have different deadlines and payment recipients. Check both before considering the year complete.
Late fees and missed-report penalties
Connecticut's LLC annual-report FAQ states there is no additional fee or penalty when an LLC report is late, but the Secretary may withhold good-standing certificates and administratively dissolve an LLC more than one year in default. Corporation late filings can lead to a notice of intent to dissolve/revoke and require all missing reports; the fee schedule lists corrected reports at $100.00 for stock corporations. Tax and franchise-tax late-payment penalties and interest are separate.
Administrative dissolution and notices
When Connecticut sends a Notice of Intent to Dissolve or Revoke, missing annual or first reports must be accepted within 90 days of the notice to avoid forfeiture or revocation. If the entity has already received a Certificate of Dissolution or Revocation, a domestic business must use the reinstatement flow, while a foreign business must re-register to transact business. The Secretary's current guidance says expedited reinstatement review is within one business day and ordinary review is usually 3–5 business days.
Reinstate a Connecticut business
Read the notice and search the Business.CT.gov record. File every missing annual report or first report, using the entity name or ALEI, and pay the required report fees. If domestic and already dissolved, submit the Certificate of Reinstatement; the fee schedule lists $300.00 for stock corporations including the required annual report and $120.00 for LLC reinstatement including the report. Restore a valid statutory agent, select expedited service if needed, and verify the status is active with a future annual-report due date.
Reinstatement costs and back taxes
Connecticut reinstatement fees include the required current annual report: $300.00 for an administratively dissolved domestic stock corporation and $120.00 for a domestic LLC under the fee schedule. Add every other delinquent report, franchise tax, and tax penalty/interest owed to the Department of Revenue Services. Foreign entities that were revoked generally re-register rather than use domestic reinstatement. The exact amount is entity-specific and shown by the filing flow.
