To set up a coffee shop in Illinois, handle entity, tax, and health approvals first: form an LLC with the Illinois Secretary of State, get an EIN, register on MyTax Illinois for an IBT number plus sales (Retailers’ Occupation) and withholding tax, then obtain your city business license and local zoning. Submit health department plan review before construction with menu, equipment schedule, and scaled floor plan; have a Certified Food Protection Manager with Illinois allergen training whenever open, and ensure all staff complete approved food handler training within 30 days. Buildout must pass building, plumbing, electrical, fire, and occupancy inspections: provide hand sinks and a mop sink, indirect waste, backflow prevention on espresso and ice lines, ventilation, and a grease interceptor if cooking or baking triggers local code. Specify 208–240V dedicated circuits for espresso and grinders, water filtration/softening to protect boilers (target 50–150 ppm hardness), and ADA-compliant counters and restrooms. Configure your POS to collect 6.25% state sales tax plus local rates and any municipal food-and-beverage taxes. Set up workers’ comp, IDES unemployment, and payroll; meet minimum wage and the Illinois Paid Leave for All Workers Act. For revenue, secure sidewalk café permits, music licensing, and exclusivity in your lease.
