Welcome to the City of Chicago
Business License Application System

A New Way to Apply

Our new and improved Chicago Business License Application System enables new business owners, and/or their legal representatives, to conveniently apply for City of Chicago business licenses online.

For existing license holders, updating your business account information has never been easier! Now, the Chicago Business License Application System has more functionality that allow entrepreneurs to focus their time on their own business, and less time at City Hall.

Thank you for using the Chicago Business License Application System, and please contact our Small Business Center if you need assistance.
