How to Get a Business License in Kent: What You Need to Know (2026)
The Quick Version
Starting a business in Kent, WA requires permits and registrations across multiple government layers — federal, state, King County (county), and city. The primary city-level requirement is the Business License, issued by the Finance Department. 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 Finance Department at 253-856-5210 for current requirements. More information is available at kentwa.gov.

The Permit Stack: What You Need
Most businesses in Kent 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 (WA): LLC or Corporation filing through the Washington Secretary of State. Filing fee: $200 LLC, processing time: 1-2 weeks.
County (King County): Health permits (for food businesses), building inspections, and any county-specific requirements.
City (Kent): Business License from the Finance Department. Phone: 253-856-5210.
How Long Does It Take?
Most businesses in Kent 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.
