Chicago BACP
Website: chicago.gov/bacp
One of the most complex systems in the US. Most businesses need a specific license type.
Visit chicago.gov/bacp — look for "Business License," "Business Tax Certificate," or "Business Registration."
Most cities now have online applications. Some still use paper forms you mail or drop off.
You'll need: your business name, address, what you do, your SSN or EIN, and sometimes estimated annual revenue.
Typical cost in Chicago: $250–$750+ (type-based). Pay online or by check.
Usually takes 2–6 weeks. Physical businesses post their license where customers can see it.
A city license doesn't cover state requirements. See the Illinois state guide.
Most Chicago licenses need to be renewed every year. Missing it means a fine. Set a calendar reminder now.
