Connecticut LLC Frequently Asked Questions
How much does it cost to form an LLC in Connecticut?
The Connecticut state filing fee is $120. Additional costs include a registered agent ($100-$300/year, though many services offer the first year free), EIN application (free from IRS or $50-$150 through a service), and the annual report fee of $80. Most Connecticut entrepreneurs spend between $200-$620 total to form their LLC, depending on which services they choose and whether they need expedited processing (+$50).
Do I need a registered agent for my Connecticut LLC?
Yes, Connecticut law requires every LLC to have a registered agent with a Connecticut street address (P.O. boxes are not acceptable). The registered agent receives legal documents and official state correspondence on behalf of your LLC. You can serve as your own registered agent if you have a Connecticut address, but most business owners use a professional service for privacy and reliability. Some services include the first year free.
How long does it take to form an LLC in Connecticut?
Connecticut offers very fast LLC processing when filing online - processing is almost immediate. Standard processing takes approximately 5 business days. For urgent needs, Connecticut offers expedited processing for an additional $50 fee, which processes your LLC within 24 hours. Mail filings take much longer at 3-4 weeks, so online filing is strongly recommended.
What is Connecticut's annual report requirement?
Connecticut LLCs must file an annual report between January 1st and March 31st each year with an $80 filing fee. Your first annual report is due in the year following your LLC formation. The report must be filed online through Connecticut's "One Stop" business center. The state will send email reminders approximately one month before the deadline. Late filing can result in penalties and potential dissolution.
Can I form a Connecticut LLC if I don't live in Connecticut?
Yes, you don't need to be a Connecticut resident to form a Connecticut LLC. However, you must have a registered agent with a Connecticut street address. This is where professional registered agent services become essential for out-of-state business owners. Keep in mind you may also need to register as a foreign LLC in your home state if you're conducting business there.
What are the advantages of forming an LLC in Connecticut?
Connecticut offers strategic advantages including prime access to Northeast markets (NYC and Boston), a strong finance and insurance industry presence, various tax incentives through Enterprise Zone programs, and established business infrastructure. The state's high per-capita income means access to affluent consumers, though businesses should consider higher operational costs in their planning.
