Step-by-Step Connecticut Business Formation Process
Step 1: Choose Your Business Structure
Selecting the right business idea structure forms the foundation of your Connecticut business venture.
| Business Structure | Liability Protection | Tax Treatment | Formation Complexity |
|---|---|---|---|
| Sole Proprietorship | None | Pass-through | Simple |
| Limited Liability Company (LLC) | Personal assets protected | Pass-through or corporate | Moderate |
| Connecticut Corporation (C-Corp) | Personal assets protected | Double taxation | Complex |
| S Corporation | Personal assets protected | Pass-through | Complex |
| General Partnership | None | Pass-through | Simple |
| Limited Partnership (LP) | Limited for some partners | Pass-through | Moderate |

| Non-Profit Corporation | Personal assets protected | Tax-exempt (if qualified) | Complex |
Step 2: Name Your Business
Your business name serves as the foundation of your brand identity and must comply with Connecticut's specific naming requirements.
Each business structure follows different naming rules, and you'll want to select a name that's memorable, searchable, and legally compliant.
- Connecticut limited liability company names must include "Limited Liability Company," "LLC," or "L.L.C." somewhere in the name.
- Connecticut corporation names must include a corporate designator such as "Corporation," "Incorporated," "Company," or their abbreviations "Corp.," "Inc.," or "Co."
- Limited partnership names must include "Limited Partnership" or "L.P." at the end of the name.
- Limited liability partnership names must include "Limited Liability Partnership," "L.L.P.," or "LLP."
- Sole proprietorship businesses operating under a name different from the owner's legal name must register a trade name certificate with the Connecticut Secretary of State.
- Non-profit corporation names must include "Corporation," "Incorporated," or similar designators and cannot mislead the public about the organization's charitable nature.
Use the Connecticut Secretary of State's online database to check if your desired business name is available.
Consider federal trademark registration for broader protection to avoid legal issues and strengthens your brand identity.
Step 3: Register Your Business
Business registration with the Connecticut Secretary of State officially establishes your legal entity and provides liability protection for applicable business structures.
Each business type requires specific documents and follows different filing procedures.
- LLC formation requires filing a Certificate of Organization with the Secretary of State. The filing fee is $120 and processing typically takes 7-10 business days.
- Connecticut corporation formation requires filing a Certificate of Incorporation. Corporation filing fee is $250, with additional costs based on authorized share amounts.
- Limited partnership formation requires filing a Certificate of Limited Partnership, detailing general and limited partner information. It costs $120 to submit this document.
- Sole proprietorships don't require state registration but must file a trade name certificate for $20 with the local town clerk if operating under a different name. As of January 2025, trade name certificates expire after 5 years and must be renewed.
- Non-profit corporations file Articles of Incorporation with the SOS.
All registered business entities must designate a registered agent; a person or company authorized to receive legal documents on behalf of the business. The registered agent must have a Connecticut address and be available during business hours.
You can serve as your own registered agent, hire a professional service, or designate another individual.
Step 4: Write an Operating Agreement
An operating agreement outlines how your LLC is run, covering ownership, management, and profit distribution.
While not required in Connecticut, having one helps prevent disputes and clarifies member relationships.
It sets rules for decision-making, handling disputes, and operational procedures, offering flexibility but must comply with state laws.
Step 5: Get Federal and Connecticut State Tax IDs
Most Connecticut businesses need both federal and state tax identification numbers to pay business taxes.
Connecticut Department Tax Requirements:
- Corporate Income Tax: Connecticut corporations pay tax on income sourced from within the state. The state income tax rate starts at 7.5% for income up to $100,000 and increases to 9.75% for income over $100,000. A minimum tax of $250 is required regardless of the business income.
- Business Entity Tax: LLCs and other pass-through entities must pay a $250 annual tax, while partnerships are taxed based on their Connecticut gross receipts. This tax applies even if the business has no profit.
- Personal Income Tax: Sole proprietors and pass-through entity owners pay personal income tax rates ranging from 2% to 6.99%, depending on income and filing status.
- Sales Tax: Businesses selling taxable goods or services in Connecticut must register and pay for sales tax of 6.35%.
- Property Tax: Businesses owning real estate or specific personal property must pay local property taxes.
Step 6: Open a Business Bank Account
Opening a separate bank account for your legal structure is essential for liability protection of your personal finances, revenue services, and tax compliance.
You’ll need business formation documents, a Connecticut tax registration number or federal employer identification number, a personal ID, and business plan (if applicable) to open the business bank account and obtain a business credit card.
Banks like Bank of America, Wells Fargo, and local options such as Webster Bank offer business accounts.
Step 7: Obtain Required Licenses and Permits
Business licenses and permits in Connecticut depend on your industry, location, and activities.
Professional licenses are required for regulated professions, while industry-specific permits apply to businesses like restaurants or retail.
Local zoning and building permits may also be required.
Step 8: Get Business Insurance
Business insurance protects you from various risks, with coverage types depending on your business needs.
General liability insurance is crucial for most businesses, while professional liability is essential for service providers. Workers' compensation insurance is required for businesses with employees.
As a business owner, consult your insurance company for the best coverage plans.
