How to start a auto repair shop in Missouri (2026)
Everything a new auto repair shop in Missouri needs in the first months: registration, licenses, taxes, insurance and the yearly deadlines, with official links.
1. Register your business
Most owners form an LLC with the Missouri Secretary of State. Once it's registered, find it here to claim a free website and see your exact dates.
2. Licenses
Missouri doesn't require a statewide shop registration. Your city still needs a business license and zoning approval for a shop, and you'll need a plan for used oil and other waste.
Your city or county may also require a general business license or tax receipt.
3. Taxes

If you expect to owe $1,000 or more in federal tax for the year, you pay estimated tax four times a year.
