Forming a C-Corporation for your marketplace in Illinois requires specific state-level filings and compliance with local tax regulations. The initial step involves filing the Articles of Incorporation (Form BCA 2.10) with the Illinois Secretary of State, which carries a standard filing fee of $150. Additionally, Illinois imposes an initial franchise tax upon incorporation, calculated at $1.50 per $1,000 of paid-in capital, with a minimum fee of $25. For corporate governance, Illinois law mandates that a C-Corp must have at least one director.
As a marketplace operating in Illinois, you must also navigate the state's Marketplace Facilitator laws. If your platform facilitates sales for third-party vendors and exceeds $100,000 in gross receipts or 200 separate transactions annually, your C-Corp is legally required to collect and remit the 6.25% state sales tax. Furthermore, Illinois C-Corporations are subject to a 7.75% corporate income tax rate and a 2.5% Personal Property Replacement Tax (PPRT). Structuring your marketplace as a C-Corp allows for the issuance of multiple stock classes, making it ideal for raising venture capital.
