What is Business License?

Legal Definition
Business licenses are permits issued by government agencies that allow individuals or companies to conduct business within the government's geographical jurisdiction. It is the authorization to start a business issued by the local government. A single jurisdiction often requires multiple licenses that are issued by multiple government departments and agencies. Business licenses vary between countries, states, and local municipalities. There are often many licenses, registrations and certifications required to conduct a business in a single location.

Typically, a company's business activity and physical location (address) determines which licenses are required to operate lawfully. Other determining factors may include the number of employees and the form of business ownership, such as sole proprietor or corporation. Government agencies can fine or close a business operating without the required business licenses.
