How to Get a Business License in Stamford: What You Need to Know (2026)
The Quick Version
Starting a business in Stamford, CT requires permits and registrations across multiple government layers — federal, state, Fairfield County (county), and city. The primary city-level requirement is the Business Registration, issued by the Town Clerk. Most businesses need 5 to 10 separate registrations, and the order you complete them matters because each step has dependencies on the ones before it.
Contact the Town Clerk at 203-977-4054 for current requirements. More information is available at stamfordct.gov.

The Permit Stack: What You Need
Most businesses in Stamford need permits from four levels of government:
Federal: An EIN (Employer Identification Number) from the IRS — free and available instantly online at irs.gov/ein.
State (CT): LLC or Corporation filing through the Connecticut Secretary of State. Filing fee: $120 LLC, processing time: 2-5 business days.
County (Fairfield County): Health permits (for food businesses), building inspections, and any county-specific requirements.
City (Stamford): Business Registration from the Town Clerk. Phone: 203-977-4054.
How Long Does It Take?
Most businesses in Stamford can be fully licensed and operational within 4 to 12 weeks, depending on the business type. Simple home-based businesses can often complete the process in 2 to 4 weeks, while restaurants, bars, and businesses requiring inspections typically take 8 to 12 weeks.
The dependency chain matters — some permits can't be applied for until others are in place. Getting the order wrong means delays and wasted time.
