How to Form an LLC in Connecticut (2026 Step-by-Step Guide)

If you’re an ecommerce entrepreneur or small business owner in Connecticut, forming an LLC is one of the smartest first moves you can make. It gives you personal liability protection, tax flexibility, and legitimacy with suppliers, banks, and customers. I’ve been running ecommerce businesses for 15+ years at E-Commerce Paradise, and I’ve walked hundreds of people through LLC formation in states all across the country, including Connecticut.

Connecticut isn’t the cheapest state to form in, and the ongoing compliance is a bit more involved than some southern states, but if you live in Connecticut or do significant business there, forming your LLC in-state is usually the right move. The alternative (forming in Delaware or Wyoming) means registering as a foreign LLC in Connecticut anyway, which doubles your paperwork and fees.

Let me walk you through the exact process for forming a Connecticut LLC in 2026, including the costs, the paperwork, and the ongoing requirements.

Quick Overview: Connecticut LLC Formation

Here’s what you need to know up front:

• Filing fee: 120 dollars to file the Certificate of Organization
• Filing agency: Connecticut Secretary of the State
• Processing time: 2 to 7 business days online, longer by mail
• Annual report: Required annually, 80 dollars
• Registered agent: Required, must have Connecticut address
• Name reservation: Optional, 60 dollars to reserve for 120 days
• Tax filing: Connecticut Business Entity Tax was repealed, but income tax applies

The total first-year cost of a DIY Connecticut LLC is around 150 to 250 dollars depending on whether you use a registered agent service. With a formation service, expect 250 to 400 dollars for the first year.

Step 1: Choose Your LLC Name

Your LLC name needs to comply with Connecticut’s naming rules. These are pretty standard across states but have some specific requirements:

• The name must contain “Limited Liability Company,” “LLC,” or “L.L.C.”
• The name must be distinguishable from other business names registered in Connecticut
• The name cannot contain words that would imply it’s a different type of entity (like “Corporation,” “Inc.,” or “Limited Partnership”)
• Certain restricted words (like “Bank,” “Attorney,” or “University”) require additional licensing or approval

Before you get attached to a name, check its availability using the Connecticut Business Records Search on the Secretary of the State’s website. Search for the exact name and close variations to make sure nothing conflicts.

Also check domain name availability. Your LLC name doesn’t have to match your domain, but for an ecommerce business, you probably want them to align. Check for both .com and relevant extensions before finalizing.

If you want to lock in a name before filing, you can reserve it for 120 days by filing a Name Reservation form and paying 60 dollars. This is useful if you need time to finalize other aspects of the business before filing formation paperwork.

Step 2: Choose a Registered Agent

Connecticut requires every LLC to have a registered agent. This is a person or business that agrees to receive legal documents and official correspondence on behalf of the LLC. The registered agent must have a physical street address in Connecticut (PO boxes don’t count) and be available during normal business hours.

You have three options:

1. Be your own registered agent. If you live in Connecticut and are willing to have your address listed publicly, you can do this for free. The downside: your address goes on the public record and you have to be available to receive documents during business hours.
2. Hire a Connecticut resident. A friend, family member, or attorney can serve as your agent. This can get awkward and is usually not recommended.
3. Use a professional registered agent service. This is the most common choice. Services charge 100 to 300 dollars per year and handle everything professionally.

My top recommendation is Northwest Registered Agent. They have the best privacy policy in the industry (they don’t sell your data), their customer service is legit (real humans, no upselling), and they include a free year of service when you form with them. Their ongoing rate is 125 dollars per year, which is reasonable.

If you want the absolute cheapest option, Bizee offers a year of free registered agent service with formation, then charges 119 dollars annually after that.

Step 3: File the Certificate of Organization

This is the main document that creates your LLC. In Connecticut, it’s called the Certificate of Organization (in other states it might be called Articles of Organization). You file this with the Connecticut Secretary of the State.

You can file online through the Secretary of the State’s CONCORD business portal (fastest) or by mail. Online filing is processed within 2 to 7 business days. Mail filings can take several weeks.

Information You’ll Need

When filling out the Certificate of Organization, you’ll need:

• LLC name (must comply with Connecticut naming rules)
• Principal office address
• Mailing address (if different)
• Registered agent name and Connecticut address
• Names and addresses of members or managers
• Management structure (member-managed or manager-managed)
• Organizer name and signature

Filing Fee

Connecticut charges 120 dollars to file the Certificate of Organization. This is a one-time fee. Payment is made online or by check.

DIY or Formation Service?

You can absolutely do this yourself through the CONCORD portal. It’s not that hard. The main reasons people use formation services are:

• They don’t want their personal information on the public record
• They want guidance through the process
• They want ongoing compliance help beyond formation
• They don’t have a Connecticut address for the registered agent

If you decide to use a formation service, your options include Northwest Registered Agent (my top pick, around 39 dollars plus state fees), Bizee (free formation plus state fees), LegalZoom (starts at 79 dollars, most well-known), or MyCompanyWorks (strong compliance dashboard).

Step 4: Create Your Operating Agreement

Connecticut doesn’t legally require an operating agreement, but you should have one anyway. The operating agreement is the internal document that spells out how your LLC is owned and operated. Without one, you’re relying on default state rules, which may not fit your specific situation.

Your operating agreement should cover:

• Ownership percentages of each member
• How profits and losses are allocated
• Management structure and decision-making authority
• Voting rules
• How new members can be added
• What happens if a member wants to leave or sell their interest
• What happens if the LLC is dissolved

For a single-member LLC, your operating agreement is simpler but still important. It helps establish the separation between you and your business, which is critical for maintaining the liability protection.

You can get operating agreement templates from LegalNature for a reasonable fee. They have Connecticut-specific templates that comply with state law. For complex situations (multiple members, unusual ownership structures, investment arrangements), have an attorney customize the agreement.

Step 5: Get an EIN from the IRS

An EIN (Employer Identification Number) is like a Social Security number for your business. You need it to open a business bank account, file taxes, hire employees, and do basically anything with your LLC.

Getting an EIN is free and fast. Go to the IRS website and apply online. It takes about 10 minutes, and you get your EIN immediately. You need to have the LLC already formed before applying.

If you’re a non-US person forming a Connecticut LLC, the process is slightly different. You can’t use the online application and have to submit Form SS-4 by mail or fax instead. This takes several weeks.

Step 6: Open a Business Bank Account

Once you have your EIN and formation documents, open a business bank account. This is absolutely critical for maintaining the liability protection of your LLC. If you mix personal and business money in the same account, courts can “pierce the corporate veil” and hold you personally liable for business debts.

For ecommerce operators, I strongly recommend Relay. It’s built specifically for small businesses and integrates seamlessly with accounting software. You can open up to 20 checking accounts under one login, which is perfect if you run multiple stores or want to separate different categories of expenses. No monthly fees, no minimum balances.

Traditional banks like Chase, Bank of America, and Wells Fargo also offer business accounts, but they tend to have monthly fees, minimum balance requirements, and clunky online experiences.

Step 7: Set Up Bookkeeping

Don’t skip this step. Proper bookkeeping from day one saves you massive headaches at tax time and gives you the financial visibility to make smart business decisions.

Options for ecommerce bookkeeping:

• Finaloop is my top pick for ecommerce operators. It’s built specifically for online businesses and integrates with Shopify, Amazon, PayPal, Stripe, and other ecommerce platforms. It automates a ton of the bookkeeping work that general accounting tools can’t handle.
• QuickBooks Online is the industry standard general-purpose accounting software. Works for any business, including ecommerce, but requires more manual setup for ecommerce-specific transactions.
• Xero is a QuickBooks alternative with a cleaner interface and strong international features.

Step 8: File for Annual Reports

Connecticut requires every LLC to file an annual report. This is separate from federal and state tax returns. The annual report updates the state on your LLC’s current information (registered agent, members, addresses, etc.).

Connecticut annual report fee: 80 dollars.

The annual report is due each year by the anniversary of your LLC’s formation. Miss the deadline and Connecticut will assess late fees and eventually administratively dissolve your LLC.

Most formation services offer annual report filing as an add-on. If you’re using MyCompanyWorks, their compliance dashboard sends reminders and handles filings for you. It’s worth the extra cost if you’re prone to forgetting deadlines.

Step 9: Understand Your Tax Obligations

Connecticut LLCs face several tax considerations:

Federal Taxes

By default, single-member LLCs are taxed as sole proprietorships and multi-member LLCs are taxed as partnerships. You can elect to be taxed as an S-corp or C-corp if that’s better for your situation.

For high-income ecommerce operators (profits over around 50,000 dollars per year), an S-corp election often saves significant money on self-employment taxes. Talk to an ecommerce-focused CPA before making the election.

Connecticut State Income Tax

Connecticut has a state income tax, and LLC income flows through to members who pay state tax on it at their individual rates. Connecticut’s state income tax rates range from 3 to 6.99 percent depending on income.

Sales Tax

If you sell physical goods in Connecticut, you need to collect Connecticut sales tax (6.35 percent on most items). Register with the Connecticut Department of Revenue Services for a sales tax permit.

For ecommerce operators with customers in multiple states, the sales tax situation gets complicated. Economic nexus laws mean you may need to collect sales tax in other states where you have significant sales. Tools like TaxJar and Avalara help automate this mess.

Self-Employment Tax

As an LLC member, you pay self-employment tax on your share of the profits. Currently 15.3 percent on the first 168,600 dollars, then 2.9 percent above that (these thresholds change annually).

Step 10: Get Business Insurance

An LLC provides legal protection, but insurance provides financial protection. You need both. At minimum, consider:

• General liability insurance: covers basic business risks like customer injuries and property damage
• Product liability insurance: critical for ecommerce businesses selling physical products
• Cyber liability insurance: covers data breaches and cyber attacks

Services like LegalShield give you access to attorneys for legal questions, which is different from insurance but complements it well.

Optional: Form in Wyoming and Register as a Foreign LLC

Some Connecticut residents consider forming their LLC in Wyoming (for privacy) and then registering it as a foreign LLC in Connecticut. This can make sense for privacy-focused businesses, but it means you pay formation and annual fees in both states.

For most Connecticut-based operators, forming directly in Connecticut is simpler and cheaper. Only go the Wyoming route if privacy is a specific concern and you’re willing to pay for it.

Total First-Year Costs

Here’s what a typical Connecticut LLC costs in the first year:

• Certificate of Organization filing fee: 120 dollars
• Registered agent (first year often free with formation service, otherwise 125 dollars)
• Operating agreement template: 50 to 100 dollars (or free with some formation services)
• Business bank account: 0 dollars with Relay
• Business insurance: 500 to 1,500 dollars per year (varies widely)
• Bookkeeping software: 240 to 1,200 dollars per year
• Formation service fees (optional): 39 to 300 dollars

Bare minimum DIY: around 150 to 200 dollars for the first year (not counting insurance and bookkeeping).

Typical with formation service: 250 to 500 dollars for the first year.
