The phrase refers to a business entity formed in Illinois under the provisions of the Illinois Business Corporation Act and operating under a charter granted by the state. This type of entity is authorized to conduct specific activities and possesses certain rights and responsibilities defined by Illinois law. A for-profit company incorporated within the state serves as a concrete example.
Establishing an entity under this framework offers limited liability protection to its owners, potentially simplifying access to capital and fostering a structured approach to business operations. Historically, these entities have played a significant role in the economic development of Illinois, providing a mechanism for organizing and conducting business ventures.
