INC TX-R AND D CREDIT

Summary

SB0252 amends the Illinois Income Tax Act to make the state’s research and development income tax credit permanent. Under current law, the credit is available for qualifying research activities conducted in Illinois through a specified end date; this bill removes the sunset and provides that the credit applies on a permanent basis. The bill is effective immediately. The measure does not create a new credit or change the credit rate; it preserves the existing 6.5% credit for qualifying expenditures tied to increasing research activities in Illinois. It also retains the current rules governing what counts as qualifying expenditures, how the base period is calculated, how unused credits may be carried forward, and the existing pass-through treatment for partnerships, S corporations, and certain LLCs. In practical terms, the bill would give businesses and other taxpayers long-term certainty that the R&D credit will remain available. The bill’s impact on state law is narrow but significant: it removes the expiration date from subsection (k) of Section 201 of the Illinois Income Tax Act and makes the R&D credit a permanent feature of Illinois tax policy. Because the credit applies against the individual and corporate income tax, the bill affects taxpayers that incur qualifying research expenses in Illinois, including corporations and pass-through entities with eligible research activity. The bill does not alter other tax credits or the broader income tax rate structure. Based on the available context, the general sentiment appears favorable or at least supportive of maintaining the credit, since the bill is framed as a continuation of an existing economic development incentive rather than a new tax expenditure. However, no committee transcripts or recorded votes were provided, so there is no direct evidence of debate, opposition, or amendments in the materials supplied. The main point of potential contention is fiscal: making the credit permanent could reduce state revenue on an ongoing basis, and lawmakers may differ on whether the economic-development benefits justify that cost. Supporters would likely emphasize business retention, innovation, and competitiveness, while skeptics may question whether a permanent tax credit is the best use of state resources or whether it should remain subject to periodic review.

Impact

SB0252 would amend Section 201 of the Illinois Income Tax Act to eliminate the sunset on the research and development credit, making the credit available on a permanent basis for qualifying research expenditures conducted in Illinois. The bill leaves the credit rate, eligibility rules, carryforward provisions, and pass-through treatment intact, but it changes the duration of the credit from temporary to ongoing, thereby affecting corporate and individual income tax liabilities for taxpayers engaged in qualifying R&D activity.

Sentiment

The available materials suggest a generally positive or pro-credit posture toward the bill, because it preserves an existing incentive that is commonly used to encourage research activity and investment in Illinois. There are no committee transcripts or votes in the record provided, so there is no documented opposition or formal support to characterize beyond the bill’s pro-business framing and its purpose of providing certainty to taxpayers.

Contention

The likely area of contention is the fiscal effect of making the R&D credit permanent. Supporters would view the bill as a stability measure that encourages innovation, investment, and job creation, while critics may argue that a permanent credit reduces state revenue and should remain subject to sunset review or periodic legislative reauthorization. No specific objections, amendments, or named opponents are included in the provided context.
