Illinois has the fifth-largest economy in the US, centered on Chicago's global financial services, commodities trading, technology, food processing, and manufacturing sectors. Downstate economies are driven by agriculture—Illinois is a leading producer of corn and soybeans—along with university towns and government in Springfield. The state hosts over 1.2 million small businesses.
Illinois's flat 4.95% income tax and high corporate rate of 9.5% create notable tax obligations, while Chicago's 10.25% combined sales tax is among the highest in the nation. The state's fiscal challenges have led to periodic tax policy changes, making it important for businesses to maintain adaptable bookkeeping systems that can accommodate new requirements.
Illinois offers tax incentives through Enterprise Zones, the EDGE Tax Credit for job creation, and various industry-specific programs. Manufacturing and agricultural businesses benefit from specific exemptions, but navigating the complex interaction between state and local taxes—especially in the Chicago metro—demands professional financial management.
