Illinois Department of Commerce and Economic Opportunity

Supports Illinois economic development through programmes for enterprise growth while tax functions are handled separately.

The Illinois Department of Commerce and Economic Opportunity is Illinois's state cabinet agency for economic development, small business support, workforce training, community development, and energy transition. It administers direct state grants, passes through federal programs from agencies such as HUD, SBA, the US Department of Labor, DOE, and EPA, and manages the $3 billion ReBuild Illinois capital initiative.

Its funding lines range from SBIR and STTR matching grants to tourism support, industrial site readiness, clean-energy workforce hubs, community infrastructure, and other regional awards. The agency also uses delivery partners such as SBDCs, community action agencies, local workforce boards, and certified convention bureaus, while grant administration follows Illinois's GATA uniform process. Named examples in the portfolio include the Illinois Innovation Voucher Program, the Illinois SBIR/STTR Match Program, CEJA energy transition grants, the Clean Jobs Workforce Network, ETIP, and ReBuild Illinois capital grants.

The strongest fit is a municipality, nonprofit, workforce intermediary, or company with an existing federal award, a site-readiness need, or a clean-energy or industrial project that matches a live state call. Applicants need to work to deadline, follow the partner network when one is required, and show a clear public-purpose outcome that fits the program's rules.
