Forming a Connecticut LLC: $120 Filing Fee, Complete Walkthrough

Connecticut charges $120 to file Articles of Organization with the Secretary of State. Annual maintenance includes an $80 report and $99/year for a registered agent. The state processes formations in 5-7 business days (expedited: 24 hours for $50). Here is every step, every cost, and every ongoing obligation.

Why a Connecticut LLC

A limited liability company shields your personal assets from business debts and lawsuits. If the entity faces a claim, creditors generally cannot pursue your home, savings, or personal property — provided you maintain proper separation between yourself and the business.

Connecticut LLCs benefit from:

• Pass-through federal taxation (profits on your personal return, no entity-level federal tax)
• Flexible management structure (member-managed or manager-managed)
• Fewer formalities than a corporation (no required board meetings or stock issuance)
• Strong judicial precedent protecting LLC liability shields

Cost Summary

First-year total (formation + agent): $219 minimum. Ongoing: $179/year (report + agent) plus any applicable BET.

Formation Steps

1. Choose a compliant name

Must contain "Limited Liability Company," "LLC," or "L.L.C." and be distinguishable from all existing Connecticut entities. Search the Secretary of State's database at portal.ct.gov/sots before finalizing.

2. Appoint a registered agent

Connecticut requires an agent with a physical in-state address, available during business hours. Individual agents must be Connecticut residents and must disclose their residential address (which becomes public record). We serve as your agent for $99/year — our address appears publicly instead of yours.

3. File Articles of Organization

Submit to the Connecticut Secretary of State with the $120 fee. Include your LLC name, registered agent information, principal address, management structure, and organizer details. File online at portal.ct.gov/sots for fastest processing.

Standard: 5-7 business days. Expedited ($50 additional): approximately 24 hours.

4. Prepare an operating agreement

Connecticut does not require filing this with the state, but it governs your LLC's internal operations: ownership percentages, profit distribution, voting authority, and member departure terms. Banks require it for account opening. Courts look to it in disputes. Draft one before you begin business operations.

5. Obtain a federal EIN

Apply free at IRS.gov. Takes approximately ten minutes. Required for business banking, hiring employees, and filing federal taxes. Do not pay a third-party service for this.

6. Ongoing compliance

• File the $80 annual report every year
• Maintain your registered agent continuously
• Pay the Business Entity Tax if your LLC is treated as a corporation ($250 minimum)
• Keep business and personal finances strictly separate
• Handle federal and state tax obligations

Missing the annual report or losing your registered agent can trigger administrative dissolution — ending your entity's liability protections until reinstated.

The Registered Agent Obligation

Every Connecticut LLC must name a registered agent at formation and maintain one indefinitely. The agent's address becomes part of the Secretary of State's publicly searchable database.

If you serve as your own agent, Connecticut requires you to disclose your residential address — which then appears in public records permanently. This is a more aggressive disclosure requirement than most states impose.
