Filing a Connecticut Annual Report? Know the Deadlines, Fees & Steps

Connecticut annual report filings are made online with the Connecticut Secretary of the State by LLCs and corporations. LLCs file between January 1 and March 31 for $80. Domestic stock corporations file their annual reports by the end of their anniversary month for $150, and foreign stock corporations file for $435. All reports are filed online. It takes six steps to file your annual report.

If you do not file your report, you will not be able to acquire a Connecticut Certificate of Legal Existence. The state will then issue a Notice of Intent to Dissolve or Revoke. You will have 90 days from the date of the notice to file all of your reports.

Every year, the same reasons founders miss Connecticut’s annual reports. Fees range from $50 to $435. Many older resources still print numbers that the state changed years ago. Every entity formed in another state and registered to do business in Connecticut files as well.

Does Connecticut require an annual report for your business?

Yes. The Connecticut Secretary of the State requires an annual report from LLCs, LLPs, LPs, stock corporations, and non-stock corporations. A non-resident founder who formed a Delaware or Wyoming LLC and registered it in Connecticut files as well as any LLC for non-residents that holds a Connecticut registration.

The report carries no financial information. You still file if your business made no money. Tax-exempt organizations file as well.

When is the Connecticut annual report due?

No matter when an LLC is formed, the due date is the same for all. Your formation date just determines when your first report is due. An LLC formed in October 2026 would have to file its first report between January 1, 2027, and March 31, 2027.

Although corporations share some similarities with LLCs, the rules regarding annual reports differ. For example, let’s say your corporation’s anniversary month is May. Your report would be due May 31, and you can file up to a month in advance.

While the state does send a reminder 30 days prior to the due date, the email is sent only to the address on file, which is sometimes out of date, so it goes nowhere. Check the date on the guides you reference. The rule changed for LLCs in 2018.

How much does the Connecticut annual report cost?

As of October 2026, the costs for the Connecticut annual reports are:

There is a $285 difference between a foreign and a domestic stock corporation. The gap is noticed by Connecticut business owners who formed a corporation in another state and later registered it to do business in Connecticut.

What information is required in the Connecticut annual report?

The portal requires different information based on the entity type. They are:

• Business email and street address
• Owner mailing and street addresses
• Name of registered agent, email, mobile number, and addresses
• Name of each principal, title, email, business, and residence addresses
• NAICS industry code
• Information about foreign entities, if applicable

A principal is an officer or director of a corporation, or a member or manager of an LLC. The principal office address cannot be a PO Box, but the mailing address can be.

How is the Connecticut annual report filed?

Connecticut allows the annual report only online.

1. Create an account on Business.CT.gov or log in.
2. Select “File Annual Report” and type in the name or ID of the company.
3. Review and change the pre-filled information of addresses and principals.
4. Check the registered agent’s information. An “Agent information insufficient” message will appear if the agent record is not correct. A good registered agent updates the record.
5. Pay the fee with a credit card.
6. Submit and save the filing confirmation.

To be clear, your entity must be shown as active to file an annual report. If more than one year of reports is due, the state’s guide recommends filing the earlier years first.

What happens if the Connecticut annual report is not filed?

We could not find a fixed late fee on the state’s official pages. Rather, consequences vary by stage.

Immediately: An overdue entity cannot obtain a Certificate of Legal Existence, or, more properly, the state’s document of Good Standing. Banks, lenders, and other states often require this document.

Later: The Connecticut Secretary of the State sends a Notice of Intent to Dissolve or Revoke. A recipient has 90 days to file all overdue reports to avoid a Notice of Forfeiture or Revocation. Once the Notice is sent, the entity’s status becomes “forfeited”. The business name becomes available for use. A reinstatement filing is required to restore the entity.

Notices are sent to the principal business address and email on file. If that address is a mailbox and nobody is checking it, 90 days can go by unnoticed.

Is an annual report the same as a tax return?

No. The Connecticut annual report is an update to the entity’s records filed with the Connecticut Secretary of the State. The Connecticut Business Entity Tax, a $250 filing every two years, was repealed and will not be assessed starting in 2020. Some older guides do not reflect this change.

State tax returns are filed with the Connecticut Department of Revenue Services, and your federal return is filed with the IRS. For more information on Connecticut state tax returns for an LLC owned by a foreign person, please see our US Tax Filing page.

What common mistakes do founders make when filing Connecticut annual reports?

• Using the anniversary month for an LLC. Connecticut LLCs use a set window of January through March.
• Paying a third party. The Connecticut Secretary of State’s office has warned that going through a third party to file will cost more.
• Leaving a stale contact email. The entity will be issued a default notice for failing to file its annual report, and the reminder and dissolution notices will be sent to the email address on file.
• Skipping registration. Foreign LLCs doing business in Connecticut that have not registered will have nothing to file against.
• Relying on outdated fee schedules. There are numerous resources stating that filing a Connecticut LLC costs $20.
