SB 3873 Illinois Senate · 104th Regular Session

INC TX-R AND D CREDIT

SB 3873 permanently extends Illinois' research and development (R&D) tax credit for businesses. It amends the Illinois Income Tax Act to make the R&D credit permanent, removing any expiration date. This change directly affects businesses that claim R&D credits on their state tax returns, providing ongoing eligibility without needing annual legislative renewal. The credit applies immediately upon the bill's effective date, offering predictable tax relief for qualifying companies investing in innovation.
