Connecticut requires registered companies to submit an annual report each year to confirm they remain in active status. This simple check-in verifies your address, registered agent, and key people like officers or managers. When you file, your information becomes public record, letting banks, partners, and customers verify you're legitimate through the state's online portal.

Skipping this filing exposes your company to losing good standing, making it impossible to get a Certificate of Legal Existence. After enough time passes without filing, Connecticut can dissolve your business through an administrative process. That means losing your liability protection and your exclusive claim to your business name.

As of January 1, 2025, Public Act 24-111 introduced several changes to the annual report process, including a new amended annual report requirement, email-based dissolution notices, and a mandatory NAICS code field. Businesses should review their filing obligations to account for these updates.

Who must file?

If you have a business registered in Connecticut, you need to file an annual report. The rule applies to almost everyone:

• Corporations (both profit and non-profit)

• LLCs

• LLPs

• LPs

• Foreign entities qualified to do business in Connecticut

Per the CT Business Services portal, sole proprietorships and general partnerships don't need to file, because they didn't register with the state to begin with. Connecticut statutory trusts are also exempt from the annual report requirement. Incorporated church or religious corporations and cemetery associations are exempt under CGS § 33-1243 as amended by P.A. 24-111. Cooperative associations must file, but they operate under a separate regime with different deadlines, fees, and a PDF-based process rather than the online portal.

You've got options for who submits the report. For LLCs, any member, manager, or authorized person can file. Corporations rely on officers or directors. You can also delegate this task to your Connecticut registered agent or a compliance service.

Connecticut has moved everyone to its online filing portal. Online filing is your fastest option, and generally your only choice for standard entities. You'll need a Business.CT.gov account, a credit card, and your business's ALEI number (Authoritative Legal Entity Identifier), which you can find by searching the Business Records Search by name.

Here's the process:

1. Log into your Business.CT.gov dashboard (or create an account)

2. Select your business and click "File annual report"

3. Verify your legal name and address

4. Review and update your principal information (officers, directors, managers, or members as applicable to your entity type)

5. Review your registered agent info and update it if needed

6. Select your NAICS code (6-digit industry classification) to identify your business activity

7. Provide your email address and contact details for state follow-up

8. Pay the filing fee

9. Certify everything's accurate and submit

10. Download your stamped confirmation

The official domestic forms and fees page confirms all annual reports must be filed online. Paper filings are strongly discouraged and result in much longer turnaround times. Cooperative associations are the exception; they file via a separate PDF form.

No specific processing time is stated in official sources. Expedited service is available only through online filing and is presented at the end of the filing flow before payment.

Due dates and deadlines

Connecticut doesn't give everyone the same deadline. Check your specific date in the Business.CT.gov portal.

• LLCs, LLPs, and LPs must file by March 31 each year, with the filing window opening January 1.

• Corporations (stock and non-stock) must file by the last day of the anniversary month of formation or registration.

• Cooperative associations face an earlier March 10 deadline.

Miss your deadline, and your company loses its ability to obtain a Certificate of Legal Existence immediately. Administrative dissolution proceedings can follow after the applicable default period.

Filing fees

Connecticut charges a flat fee per entity type, regardless of size or revenue. You pay when you submit, and the amount depends on your legal structure. No financial information is required on the report.

‍

The $25 amended annual report fee is new as of January 1, 2025 under P.A. 24-111. Under CGS § 34-247k(g), entities must file an amended report when required information (other than the entity name) changes after the most recent annual report filing, provided the change occurs no later than 30 days before the next annual report's due month.

According to the SOTS Annual Report FAQ, there is no additional fee or penalty for missing the filing deadline for LLCs, LLPs, LPs, and corporations. Your bigger concern is losing good standing and facing administrative dissolution. The exception: cooperative associations face a $50 late fee for filings submitted after March 10, plus a separate $50 penalty per missed filing under CGS § 33-192.

Required information

Connecticut wants to know who you are, where to find you, and who's in charge. Gather these details before logging in.

Every entity provides the same basic information:

• Legal name and Business ID number (ALEI)

• Principal office address and mailing address

• Email address and contact information for state follow-up

• Your Connecticut registered agent's name and street address

• Your NAICS code (6-digit industry classification, required as of January 1, 2025)

Different entity types have different additional requirements. Stock and non-stock corporations must list the name, title, residence address, and business address of each officer and director. LLCs must list at least one member or manager with their name, title, and addresses. LPs must name their general partner(s). LLPs must also list their partners on the report.

To finish, you certify accuracy with an electronic signature and submit payment. Accepted payment methods include Mastercard, Visa, Discover, and American Express.

Consequences of not filing

Missing your Connecticut deadline triggers a defined sequence of consequences, but dissolution is not automatic. The Secretary of State must initiate a formal notice-and-cure process before an entity can be dissolved.

First, you lose your ability to obtain a Certificate of Legal Existence (good standing) immediately upon missing the deadline. This matters for financing transactions, regulatory applications, and contract requirements.

After the applicable default period, the Secretary of State may begin dissolution proceedings. The threshold varies by entity type. For stock corporations (CGS § 33-890), LLCs (CGS § 34-267g), LLPs (CGS § 34-422), and LPs (CGS § 34-32b), the threshold is more than one year past due. For non-stock corporations (CGS § 33-1181), the threshold is more than two years past due.

Once the threshold is met, the Secretary sends a Notice of Intent to Dissolve by email to the address on file. Entities then have three months from the sending of that notice to file all past-due reports and avoid dissolution.

If the cure window expires without action, the Secretary files a certificate of dissolution or forfeiture. At that point, your entity loses its legal right to operate, sue, or keep the business name you've built. Another entity may register that name during the dissolution period. For foreign entities, the consequence is revocation of the certificate of authority to transact business in Connecticut.

Connecticut generally doesn't charge late fees for standard entities, but that doesn't make it free to skip filing. Cooperative associations do face penalties as described above. You'll also need to pay all standard filing fees you missed when reinstating.

Getting back in good standing takes several steps:

1. File every overdue report through the Business.CT.gov portal

2. Pay the standard fees (plus any penalties for cooperatives)

3. Submit a reinstatement application with the required reinstatement fee

4. For LLCs: provide written consent of a majority in interest of members and appoint a registered agent

5. For corporations: provide required statements from the Commissioner of Revenue Services and the administrator of the unemployment compensation law

6. If your business name was taken during dissolution, simultaneously amend your formation documents to an available name

7. Once approved, request a new Certificate of Legal Existence and resume normal operations

Stock and non-stock corporations have an additional option: revocation of dissolution within 120 days of an accidental dissolution, at a cost of $50 for stock corporations or $20 for non-stock corporations.

FAQs about Connecticut's annual report

Below are answers to some of the most common questions about the Connecticut annual report filing process.

Can I file my Connecticut annual report early?

Yes. For LLCs, LLPs, and LPs, the filing window opens January 1, so you can file as soon as the new year begins. For corporations, the annual report is due by the last day of your anniversary month.

What if I need to correct something after I press "submit"?

You can file an amended annual report ($25 fee) to correct information. Under CGS § 34-247k(g), entities are required to file an amended report when information other than the entity name changes after filing, provided the change occurs no later than 30 days before the next annual report's due month.

How do I get a Certificate of Legal Existence?

Once your report shows "active" in the portal, you can request the certificate online. If your report is overdue, the certificate option disappears until you file and regain good standing.

Can I file multiple missed years at once?

Connecticut processes each report individually. The portal queues outstanding years and walks you through them one by one, charging the standard fee for each.

Who can submit the report on my behalf?

An "authorized person" can file: LLC members or managers, corporate officers or directors, your registered agent, or a compliance service you've hired.

Do I still need to file if my business has no revenue?

Yes. Connecticut requires annual reports regardless of whether the entity is generating revenue or profit, or holds 501(c)(3) tax-exempt status. The report contains no financial information.
