The steps to make it official
- 1
Pick your business structure
Most first businesses in St. Louis choose an LLC for the liability separation between the business and your personal life. Sole proprietorships are simpler but offer no separation; corporations fit businesses raising investment.
- 2
Check that your business name is free
Search the Missouri Secretary of State's business registry to confirm nobody in Missouri already holds the name, and check the matching web domain at the same time.
- 3
File your formation documents with the Missouri Secretary of State
An LLC or corporation forms at the state level, not the city level. File directly with the Missouri Secretary of State and pay only the state's filing fee. You will need a registered agent with a physical address in Missouri; if you live here, you can usually be your own.
- 4
Get your EIN free from the IRS
The Employer Identification Number is the business's tax ID. The IRS issues it directly at irs.gov in about five minutes, at no charge. Never pay anyone for an EIN alone.
- 5
Register with the city and check licenses
Most businesses operating in St. Louis need a city business tax registration and possibly zoning or health permits. Check the city's finance office and your local city hall for what applies to your specific business and location.
- 6
Open the business bank account and connect payments
Keep business money separate from day one: it protects the legal separation your LLC exists for and keeps taxes clean. Bring your EIN and formation documents to the bank.
Registering it is one step. Building it is the journey.
