Connecticut LLC Licenses and Permits (2026)

Learn which licenses and permits a Connecticut LLC may need in 2026, including sales tax, local permits, professional licensing, employer accounts, and regulated work.

Forming a Connecticut LLC does not automatically give the business every license it needs. The $120 Certificate of Organization creates the LLC. Licenses and permits depend on what the business sells, where it operates, whether it hires, and whether the industry is regulated.

Quick answer

Sales and use tax permit

If the LLC sells taxable goods or taxable services in Connecticut, it may need a sales and use tax permit from DRS. DRS lists the permit fee as $100.

Connecticut does not have local sales tax rates added by cities or towns. That makes the rate map simpler than some states, but the business still needs to know whether its product or service is taxable and whether remote seller or marketplace rules apply.

Local and industry permits

Even without local sales tax add-ons, local rules can matter. Check:

• Zoning
• Building permits
• Sign permits
• Food and health department rules
• Fire marshal requirements
• Local certificates or permits for physical locations

Regulated industries may also need state-level licensing before doing business.

Employer setup

If the LLC hires employees, review:

• EIN
• Connecticut withholding registration
• Connecticut unemployment registration
• New hire reporting
• Workers’ compensation
• Payroll filing calendar

This should happen before wages are paid, not after the first payroll mistake.

Common mistakes

Thinking LLC approval equals permission to operate

Secretary of the State approval creates the entity. It does not approve every business activity.

Missing the $100 sales tax permit

The sales and use tax permit is separate from LLC formation.

Ignoring professional licensing

Some industries require approval before advertising or serving customers.

Registering for tax accounts too casually

Some registrations create return-filing duties even during periods with no sales or payroll.
