Connecticut LLC Annual Report: Filing Guide, Fees & Deadlines (2026)

Connecticut LLCs must file an annual report every year by March 31 to maintain good standing with the state. Missing this crucial deadline can result in penalties and even administrative dissolution of your LLC, making it essential to understand the filing requirements and stay compliant.

What Is the Connecticut LLC Annual Report?

The Connecticut LLC annual report is a mandatory filing that all limited liability companies must submit to the Connecticut Secretary of State each year. This report serves as an official update to the state regarding your LLC’s current information, including its principal office address, registered agent details, and member or manager information. The requirement is established under Connecticut General Statutes Section 34-243, which mandates that every LLC authorized to transact business in Connecticut must file this report annually.

Every Connecticut LLC, whether domestic (formed in Connecticut) or foreign (formed in another state but registered to do business in Connecticut), must file an annual report. This requirement begins the year after your LLC is formed and continues every year thereafter as long as your LLC remains active. The annual report ensures the state maintains accurate, up-to-date records for all business entities and provides a mechanism for the state to verify that LLCs are still operational.

Unlike some states that require biennial reports or have different filing schedules based on formation date, Connecticut keeps it simple with a universal March 31 deadline for all LLCs. This consistency makes it easier for business owners to remember their filing obligations, but it also means there’s no excuse for missing the deadline.

When Is the Connecticut LLC Annual Report Due?

The Connecticut LLC annual report is due on March 31 of each year, regardless of when your LLC was formed or registered in the state. This fixed deadline applies to all LLCs and doesn’t vary based on your fiscal year or formation date. The Connecticut Secretary of State typically begins accepting annual report filings in early January, giving you approximately three months to complete and submit your report before the deadline.

For newly formed LLCs, the first annual report is due on March 31 of the year following formation. For example, if you form your LLC any time in 2025, your first annual report would be due March 31, 2026. This means LLCs formed early in the year get nearly a full year before their first filing, while those formed late in the year have only a few months. It’s crucial to mark this date in your calendar immediately after forming your LLC to avoid missing this important deadline.

The state does not send reminders about the annual report deadline, making it the LLC’s responsibility to remember and file on time. Many Connecticut business owners set up recurring calendar reminders or work with registered agents who provide compliance notifications to ensure they don’t miss this critical filing date. Since the deadline falls at the end of the first quarter, it often coincides with other business obligations, so planning ahead is essential.

How Much Does the Connecticut LLC Annual Report Cost?

The Connecticut LLC annual report filing fee is $80 for the 2026 filing year. This fee must be paid at the time of filing and can be submitted electronically if filing online or by check if filing by mail. The Connecticut Secretary of State accepts credit cards, debit cards, and ACH payments for online filings, making the payment process quick and convenient for most business owners.

If you miss the March 31 deadline, Connecticut imposes a $50 late fee in addition to the regular $80 filing fee, bringing your total cost to $130. This late fee applies immediately after the deadline passes, so filing even one day late on April 1 will trigger the additional charge. The state does not offer a grace period or waive late fees for first-time filers, making timely filing crucial for keeping costs down.

For LLCs that fail to file their annual report for an extended period, the costs can escalate significantly. If your LLC is administratively dissolved for non-compliance, reinstatement requires filing all missed annual reports with applicable late fees, plus a $150 reinstatement fee. This means an LLC that hasn’t filed for several years could face hundreds of dollars in fees to return to good standing. Additionally, dissolved LLCs may face tax consequences and lose important legal protections, making the $80 annual fee a small price to pay for maintaining compliance.

How to File Your Connecticut LLC Annual Report: Step-by-Step

Step 1: Gather Required Information

Before starting your Connecticut LLC annual report, collect all necessary information to ensure a smooth filing process. You’ll need your LLC’s Connecticut business ID number, current principal office address, registered agent name and address, and details about your LLC’s members or managers. If any of this information has changed since your last filing, have the updated details ready. Also, prepare your payment method, whether it’s a credit card for online filing or a check for mail filing.

Step 2: Access the Connecticut Business Registry

Navigate to the Connecticut Secretary of State’s business services website at business.ct.gov. Look for the “File Annual Report” option, which is typically prominently displayed during filing season. You can also access the filing system through the CONCORD online business filing system, which the state uses for most business filings. If you prefer to file by mail, you can download the annual report form from the Secretary of State’s website.

Step 3: Log In or Create an Account

To file online, you’ll need to either log into your existing CONCORD account or create a new one if this is your first time using the system. The account creation process is straightforward and requires basic contact information. Having an account allows you to save your filing progress, access filing history, and receive electronic confirmations of your submissions. This account will be valuable for future filings and other business-related transactions with the state.

Step 4: Complete the Annual Report Form

Once logged in, search for your LLC using either the business name or ID number. The system will pre-populate much of your LLC’s information based on state records. Review all pre-filled information carefully and update any details that have changed. Pay special attention to your registered agent information, principal office address, and member/manager details. Connecticut requires you to list at least one member or manager, including their name and business address. Double-check all information for accuracy before proceeding.

Step 5: Review and Submit

After completing all required fields, review your entire annual report for accuracy. The system will typically show you a summary of your filing before final submission. Verify that all addresses are current, names are spelled correctly, and contact information is up to date. Any errors in your annual report could cause problems with official correspondence or legal notices. Once you’re confident everything is correct, submit your report and proceed to payment.

Step 6: Make Payment and Obtain Confirmation

Complete your filing by submitting the $80 filing fee through the online payment system. After successful payment, the system will generate a confirmation page and send a receipt to your email address. Save or print this confirmation for your records, as it serves as proof of filing. The Connecticut Secretary of State typically processes online filings within 3-5 business days, after which you can download an official filed copy of your annual report from your CONCORD account. Keep this filed copy with your important LLC documents.

What Happens If You Don’t File?

Failing to file your Connecticut LLC annual report by March 31 triggers immediate consequences that can escalate quickly. The first and most immediate impact is the $50 late fee that applies starting April 1, increasing your total filing cost to $130. However, the financial penalty is just the beginning of potential problems for non-compliant LLCs. The Connecticut Secretary of State maintains strict enforcement of annual report requirements and doesn’t offer extensions or waivers for missed deadlines.

If your LLC continues to neglect its annual report filing obligation, the state will eventually move toward administrative dissolution. While Connecticut doesn’t immediately dissolve LLCs for missing one annual report, continued non-compliance will result in your LLC losing its good standing status and eventually being administratively dissolved. This process typically occurs if you fail to file for multiple years or ignore notices from the Secretary of State. Once dissolved, your LLC loses its legal existence in Connecticut, meaning it can no longer conduct business legally, enter into contracts, or maintain lawsuits in its LLC name.

Reinstatement after administrative dissolution requires significant effort and expense. To reinstate your Connecticut LLC, you must file all missing annual reports with their associated late fees, pay a $150 reinstatement fee, and submit a reinstatement application. The total cost can easily exceed several hundred dollars if multiple years of reports are missing. Additionally, during the period of dissolution, your LLC name becomes available for other businesses to use, potentially forcing you to operate under a different name if another entity claims it. The reinstatement process can take several weeks, during which your business operations may be severely impacted.

Frequently Asked Questions

Can I file my Connecticut LLC annual report before January?

No, Connecticut does not accept annual report filings before the calendar year in which they’re due. The filing system typically opens in early January for reports due March 31 of that year. For example, you cannot file your 2026 annual report in December 2025. This restriction ensures that the information in your annual report reflects your LLC’s current status at the beginning of the reporting year. Plan to file between January 1 and March 31 to meet your obligation without incurring late fees.

What information can I update in my Connecticut LLC annual report?

The Connecticut LLC annual report allows you to update several key pieces of information about your LLC, including your principal office address, registered agent name and address, and member or manager information. You can add or remove members/managers and update their addresses. However, you cannot change your LLC’s name through the annual report; name changes require a separate amendment filing with additional fees. If you need to make substantial changes to your LLC’s structure or operating agreement, those typically require separate amendment filings beyond the scope of the annual report.

Do single-member LLCs have different annual report requirements in Connecticut?

No, single-member LLCs in Connecticut have the same annual report requirements as multi-member LLCs. All LLCs must file by March 31 and pay the same $80 fee. The main difference is that single-member LLCs will list only one member in their annual report, while multi-member LLCs must list all members or managers. Single-member LLCs must still maintain a registered agent and provide all other required information in their annual report, ensuring the state has current contact and location information regardless of the LLC’s ownership structure.

Can I file multiple years of Connecticut LLC annual reports at once?

Yes, if you’ve missed previous annual report filings, you can file multiple years at once through the Connecticut Secretary of State’s website. You’ll need to file each missed year’s report separately and pay the $80 filing fee plus the $50 late fee for each delinquent report. The system will typically require you to file reports in chronological order, starting with the oldest missing report. Be prepared for significant costs if you’re filing several years at once, as each report incurs its own fees plus late penalties.

Does Connecticut send reminders about annual report deadlines?

Connecticut does not typically send courtesy reminders about annual report deadlines to LLCs. It’s the responsibility of each LLC to remember and meet the March 31 deadline each year. This is why many LLC owners set up their own reminder systems or work with registered agents who provide compliance notifications. Some business owners add recurring calendar reminders, use business compliance software, or rely on their accountants or attorneys to track filing deadlines. Don’t wait for a reminder from the state, as you likely won’t receive one until after you’ve already missed the deadline and incurred late fees.

Bottom Line

Filing your Connecticut LLC annual report by March 31 each year is a fundamental requirement for maintaining your LLC’s good standing and legal protection in the state. At just $80 per year, it’s a small price to pay for keeping your business compliant and avoiding the much higher costs associated with late fees, administrative dissolution, and reinstatement. The online filing process through the Connecticut Secretary of State’s CONCORD system is straightforward and typically takes less than 30 minutes to complete when you have all necessary information ready.

Don’t risk your LLC’s good standing by neglecting this important annual obligation. Mark March 31 on your calendar now, set up reminders for early March to give yourself plenty of time, and consider filing as soon as the system opens in January to get it off your plate early. Remember that the state won’t remind you about this deadline, so the responsibility falls entirely on you as the business owner. By staying proactive about your Connecticut LLC annual report filing, you’ll maintain compliance, avoid unnecessary fees, and keep your business running smoothly throughout 2026 and beyond.
