INC TX-REDUCE INDIVIDUAL RATE
HB2608 would amend the Illinois Income Tax Act to lower the state income tax rate for individuals, trusts, estates, and certain pass-through entities from 4.95% to 3.75%, and to lower the corporate income tax rate from 7% to 6%. The bill applies these new rates beginning with taxable years on or after January 1, 2026, and states that it takes effect immediately upon enactment. In practical terms, it would reduce the amount of state income tax owed by most individual filers and by corporations, while also changing the rate used for pass-through entity tax calculations tied to the individual rate.
The bill’s main legal effect is to revise Section 201 of the Illinois Income Tax Act, which sets the state’s base income tax rates. It would not eliminate the income tax or alter the structure of the tax, but it would permanently replace the current individual and corporate rates with lower ones for future tax years. Because the bill amends the core rate provisions, it would directly affect state revenue collections and the tax liabilities of residents, trusts, estates, corporations, and electing partnerships or S corporations subject to the pass-through entity tax.
The available context shows no recorded committee transcript and no votes, so there is no documented debate or formal legislative sentiment in the materials provided. Based on the bill text and caption, the measure appears to be a tax-cut proposal intended to reduce income tax burdens. The absence of committee discussion or voting history means there is no evidence here of bipartisan support, opposition, or negotiated amendments.
The most likely point of contention is fiscal impact: lowering the individual rate by 1.2 percentage points and the corporate rate by 1 percentage point would reduce state revenue, which could affect funding for state programs and services. Supporters would likely frame the bill as tax relief for households and businesses, while critics would likely focus on budgetary tradeoffs and the effect on the state’s fiscal stability. Another potential issue is that the bill changes the pass-through entity tax rate indirectly by tying it to the individual rate, which would also affect partnerships and S corporations that elect entity-level taxation.
HB2608 would amend Section 201 of the Illinois Income Tax Act to change the state’s base income tax rates for individuals, trusts, estates, certain pass-through entities, and corporations. It would reduce the individual/trust/estate/pass-through rate from 4.95% to 3.75% and the corporate rate from 7% to 6%, with the new rates applying to taxable years beginning on or after January 1, 2026. This would directly lower tax liabilities for affected taxpayers and reduce projected state income tax revenue.
No committee transcripts or votes are provided, so there is no documented legislative sentiment in the record supplied. From the bill text and caption, the measure is clearly a tax-reduction proposal, suggesting a pro-taxpayer, pro-business policy direction. The lack of recorded debate means support or opposition cannot be attributed to any specific legislator or stakeholder in the provided materials.
The primary likely contention is the revenue loss from reducing both individual and corporate income tax rates, which could constrain the state budget and public services. Supporters would likely argue the bill provides broad tax relief and could improve Illinois’ competitiveness, while opponents would likely argue that the state cannot absorb the revenue reduction without cuts or offsetting taxes. A secondary issue is that the pass-through entity tax is tied to the individual rate, so the bill would also affect partnerships and S corporations that elect entity-level taxation.
