IL SB3710

Amends the Illinois Income Tax Act (35 ILCS 5/201) to make the research and development tax credit permanent, removing any existing expiration date.

Introduced by Senator Doris Turner on February 5, 2026, during the 104th General Assembly.

The bill takes effect immediately upon becoming law.

Currently, the R&D credit operates on a temporary basis requiring periodic legislative renewal; this change would eliminate the need for future extensions.
