SB 3710 Illinois Senate · 104th Regular Session

INC TX-R AND D CREDIT

SB 3710 permanently extends Illinois' research and development (R&D) tax credit under the Illinois Income Tax Act. This change makes the credit available indefinitely for eligible businesses, rather than as a temporary provision. The bill directly affects companies conducting qualifying R&D activities within Illinois that claim this tax credit. It amends Section 201 of the tax code to remove any expiration date, effective immediately upon enactment. The credit allows businesses to reduce their state tax liability based on qualified R&D expenditures.
