Forming an S Corporation in Illinois offers potential tax advantages for eligible businesses, allowing profits and losses to be passed through directly to the owners' personal income without being subject to corporate tax rates.

This guide will walk you through the essential steps, requirements, and considerations for setting up your S Corp in the Prairie State. Understanding the distinction between forming an LLC or a C Corp and electing S Corp status is crucial. An S Corp is not a business structure itself but a tax election made with the IRS. To form an S Corp in Illinois, you typically first establish a Limited Liability Company (LLC) or a C Corporation at the state level. Once your business entity is registered with the Illinois Secretary of State, you then file Form 2553, Election by a Small Business Corporation, with the IRS to elect S Corp tax treatment. This guide focuses on the Illinois-specific aspects and the subsequent federal election required to operate as an S Corp in Illinois.
