How Much Does a Connecticut LLC Cost? A Complete Startup and Ongoing Fee Guide

Starting a Connecticut LLC is straightforward, but the real cost is more than just the filing fee. You need to account for state filing charges, annual reporting, business licenses, possible name reservations, and any professional services you choose to use along the way.

If you are planning a new business in Connecticut, understanding the full cost picture helps you budget realistically and avoid surprises after formation.

Connecticut LLC Costs at a Glance

Here is the basic cost breakdown for most Connecticut LLC owners:

• Certificate of Organization filing fee: $120
• Annual report fee: $80 per year
• Name reservation fee: $60 if you choose to reserve a business name
• Certified copies: $55 per copy
• Certificate of Legal Existence: $50 for the short form or $100 for the long form or expedited version
• Business licenses and permits: varies by industry and location
• Registered agent service: varies if you hire a third party
• Insurance, taxes, and professional services: varies by business type

For the official filing forms and fees, see Connecticut’s business services pages on Business.CT.gov and the Secretary of the State’s resources.

1. The Main Connecticut LLC Formation Fee: $120

The core cost to form a Connecticut LLC is the $120 filing fee for the Certificate of Organization. Filing this document with the Connecticut Secretary of the State creates your LLC.

Connecticut allows you to file online, by mail, or in person, but online filing is usually the fastest and most convenient option.

This is the mandatory starting cost for domestic LLC formation in Connecticut. If you are creating the LLC yourself, this may be the only required state filing fee at the outset.

2. Connecticut Annual Report Fee: $80

Every Connecticut LLC must file an annual report and pay an $80 fee each year. The annual report is filed online and keeps your business information current with the state.

The report is due every year between January 1 and March 31, beginning the year after your LLC is formed.

If you miss the deadline, your business can fall out of good standing, which can create problems when you try to obtain financing, register in another state, or request a certificate of legal existence.

3. Registered Agent Costs

Every Connecticut LLC must appoint a registered agent with a physical address in Connecticut who is available during normal business hours to receive legal and official documents.

You have two basic options:

• Serve as your own registered agent
• Hire a professional registered agent service

Serving as your own registered agent can save money, but it also means your address becomes part of the public record and you must be reliably available during business hours. Hiring a professional service adds cost, but it can improve privacy and reduce the risk of missing important documents.

For many owners, the value of a professional registered agent is not just convenience. It is also compliance support and peace of mind.

4. Business Licenses and Permits

Connecticut does not use one universal license for every business. Instead, licensing depends on your industry, city, county, and activities.

Some businesses need only local permits, while others need state-level professional licenses or special registrations. Examples include businesses in industries such as:

• Construction
• Health care
• Insurance
• Real estate
• Child care
• Food service
• Transportation

The Connecticut Business Checklist tool and license pages on Business.CT.gov can help you identify what applies to your business.

Because these fees vary widely, they are often the most unpredictable part of the startup budget.

5. Optional Name Reservation: $60

If you are not ready to file your LLC right away, you can reserve your desired business name with the state for $60.

This is optional, but it may be helpful if you want to secure a name before you complete the rest of your formation process. A reservation can give you extra time to organize your filing while keeping someone else from taking the name in the meantime.

For many entrepreneurs, name reservation is not necessary. If you are ready to form the LLC now, you can usually skip this cost.

6. DBA or Trade Name Costs

If your LLC will operate under a name different from its legal name, you may need to file a DBA or trade name registration.

Connecticut DBA filing requirements are handled locally, and the cost can vary depending on the town or city where you register. Some businesses never need a DBA. Others use one for branding, storefront signage, or marketing purposes.

A DBA does not create a new legal entity. It simply lets your LLC conduct business under an alternate name.

7. Certified Copies and Certificates

After your LLC is formed, you may eventually need state-issued documents for banking, licensing, financing, or recordkeeping.

Common options include:

• Certified copy of a business document: $55 per document
• Certificate of Legal Existence: $50 for the short form or $100 for the long form or expedited version

A Certificate of Legal Existence is often requested when a business opens a bank account, seeks financing, or registers to do business in another state.

These are not startup necessities for every LLC, but they are useful to know because they can become part of your ongoing administrative costs.

8. Insurance Costs

Insurance is another major part of the true cost of starting an LLC.

Depending on your business model, you may need:

• General liability insurance
• Professional liability insurance
• Commercial property insurance
• Cyber liability insurance
• Workers’ compensation insurance, if you have qualifying employees

Insurance is often one of the smartest early investments an LLC can make. Even when it is not legally required, it can protect your business from expensive claims, property losses, and operational disruptions.

The cost depends on your industry, number of employees, claims history, location, and coverage limits.

9. Foreign LLC Costs in Connecticut

If your LLC was formed in another state and you want to do business in Connecticut, you may need to register as a foreign LLC.

The filing fee for a foreign LLC registration is also $120, and the foreign entity will still need to meet Connecticut’s ongoing compliance requirements, including annual reporting.

This matters for companies expanding into Connecticut from elsewhere. Even if your business already exists, doing business in the state can trigger Connecticut registration obligations.

10. Example Connecticut LLC Startup Budgets

Here are a few simple examples of what your first-year budget might look like.

11. How to Keep Connecticut LLC Costs Under Control

A smart startup budget is not just about spending less. It is about spending where it matters.

A few practical ways to manage your costs:

• File your LLC only when you are ready to operate
• Check whether your business actually needs a name reservation
• Use the Connecticut New Business Checklist to identify required licenses early
• Compare professional registered agent options
• Budget for insurance before you begin taking customers
• Track annual report deadlines so you do not create avoidable penalties or reinstatement costs

The cheapest option on day one is not always the best choice if it leads to missed notices, compliance problems, or avoidable delays later.

12. Why Cost Planning Matters for New Connecticut LLC Owners

A Connecticut LLC is often an efficient and flexible way to start a business, but it still comes with ongoing responsibilities. Forming the company is only the first step. Staying compliant, maintaining good standing, and keeping a proper paper trail are part of the real cost of ownership.

If you are preparing to launch a new business in Connecticut, make your budget before filing. That gives you a clearer picture of the total cost and helps you choose the right mix of DIY work and professional support.

Final Takeaway

The basic cost to start a Connecticut LLC is $120 for formation, but most owners should also budget for the $80 annual report, possible license or permit fees, and any services they choose for registered agent support, insurance, and compliance.
