To start a coffee shop in Missouri, lock down compliance first: form an LLC with the Missouri Secretary of State (online; ~$50), obtain an EIN, and register for a Retail Sales Tax License via MyTax Missouri (Form 2643) to collect state/local tax on prepared drinks. Choose a zoned, high-footfall site and secure a local business/merchant license, building permit, fire inspection, and a Certificate of Occupancy. For health approval, submit a plan review to your city/county health department with floor plan, NSF-listed equipment specs, plumbing (hand sinks, 3-compartment sink, mop sink, backflow preventers), hot-water capacity, and finish schedule; install a grease interceptor if required by your sewer district. Espresso-only operations typically don’t need a Type I hood; add one for grease-producing cooking. If roasting, confirm air permitting with Missouri DNR (small roasters may qualify for de minimis exemptions). Staff a certified food protection manager (ANSI/ServSafe) and meet any local food handler card rules. Register for unemployment insurance when you have taxable payroll; workers’ compensation is required at 5+ employees (1+ in construction). Budget $150k–$350k for buildout, equipment, and working capital; kiosks can launch for less. Expect 30–90 days for permits. File sales tax monthly or quarterly based on volume. Plan contingencies.
