Your First-Year LLC Costs

Beyond the $120 state filing fee, you’ll have several other expenses in your first year. Some are required, others are highly recommended for proper business operations.

Required Costs

State Filing Fee: $120
The Certificate of Organization costs $120 whether you file online through the Connecticut Business Portal or submit paper forms by mail. This fee covers processing your LLC formation documents.

Registered Agent: $0-125/year
Connecticut requires every LLC to maintain a registered agent at a Connecticut address. You can serve as your own registered agent for free, or hire a professional service for around $125 per year. Professional services provide privacy and ensure you never miss important legal documents.

Annual Report: $80
Connecticut LLCs must file an annual report between January 1 and March 31 each year. The report costs $80 and updates your LLC’s business information with the state.

Optional but Recommended Costs

EIN (Federal Tax ID): Free
You can obtain an Employer Identification Number directly from the IRS at no cost. Avoid third-party services that charge $50-200 for this free service. You’ll need an EIN to open business bank accounts and handle tax filings.

Operating Agreement: Free with template
While Connecticut doesn’t require an operating agreement, having one protects your limited liability status and clarifies member responsibilities. You can draft one using free templates or hire an attorney for $500-1,500.

Business Bank Account: $10-25/month
Separate business banking is essential for maintaining your LLC’s liability protection. Most banks charge $10-25 monthly for business checking accounts, though some offer fee waivers for new businesses.

Total First-Year Cost: DIY formation costs $120-200 for the basics, or $300-400 if you include professional registered agent service and business banking.

Why Use a Formation Service?

While Connecticut’s $120 filing fee might seem like the total cost, formation services provide value beyond just submitting paperwork:

Accuracy and Speed

Formation services know Connecticut’s specific requirements, including the mandatory NAICS code and proper manager/member designations. They catch errors that could delay your filing or require costly amendments.

Included Registered Agent

Most services include one year of registered agent service, worth $125 annually. This provides a professional business address and ensures you receive important legal documents promptly.

Business Tools and Templates

Quality formation services provide operating agreement templates, compliance calendars, and business formation guides. These tools help you maintain proper LLC operations from day one.

Ongoing Support

Formation services typically offer customer support for questions about compliance, filing requirements, and business operations. This guidance proves valuable as your business grows.

Additional Connecticut LLC Costs to Consider

Beyond formation, several other costs may apply depending on your business type and activities:

Business Licenses and Permits

Connecticut requires specific licenses for many business activities. A Connecticut LLC may need state licenses, local permits, or professional certifications depending on your industry. Costs vary widely by business type.

Sales Tax Permit

If your LLC sells taxable goods or services in Connecticut, you’ll need a sales tax permit. The state charges a $100 fee for businesses engaged in certain activities requiring sales tax collection.

State Tax Registration

Connecticut LLCs may owe state income tax ranging from 3% to 6.99% on business profits. You’ll need to register with the Connecticut Department of Revenue Services and may need to make quarterly estimated payments.

Professional Services

Consider budgeting for professional services as your business grows:

  • Attorney consultation: $200-500/hour for legal advice
  • CPA services: $150-300/hour for tax preparation and planning
  • Business insurance: $400-1,200/year for general liability coverage

Managing Ongoing Compliance Costs

Connecticut LLCs have relatively simple ongoing requirements, but staying compliant prevents costly penalties:

Annual Reports

File your $80 annual report between January 1 and March 31 each year through the Connecticut Business Portal. Late filings incur additional penalties.

Tax Filings

Connecticut LLCs must file state tax returns and may owe Connecticut LLC taxes on business income. Keep detailed financial records to simplify tax preparation.

Registered Agent Maintenance

Maintain your Connecticut registered agent continuously. If you use a service, expect annual renewal fees around $125.

Pro Tip: Set up automatic reminders for your annual report deadline and registered agent renewals. Missing these requirements can result in penalties or administrative dissolution.

Banking and Financial Setup

Proper financial management protects your LLC’s limited liability status and simplifies tax preparation. Setting up business banking should be one of your first priorities after formation.

Why You Need Separate Business Banking

Mixing personal and business finances can pierce your LLC’s liability protection, exposing your personal assets to business debts. Connecticut courts may disregard your LLC structure if you don’t maintain clear financial separation.

Choosing a Business Bank

Look for banks offering low monthly fees, convenient locations, and business-friendly features. Many banks waive monthly fees for new businesses or maintaining minimum balances.
