What this means for Illinois workers

This state has explicitly decoupled from BOTH the qualified-tips and the qualified-overtime federal deductions. Workers must add back the federal AGI reduction on their state return; the deductions reduce federal taxable income but not state taxable income.

Statute-cited expansion

Federal source

The federal deductions sit at 26 USC §224 (qualified tips) and §225 (qualified overtime). State conformity is keyed to whether the state uses federal AGI (or federal taxable income) as the starting point for state taxable income, and whether the state has affirmatively decoupled from §224 / §225 for state tax purposes.

  • 26 USC §224(b)(1)$25,000 federal qualified-tips cap.
  • 26 USC §225(b)(1)$12,500 single / $25,000 MFJ federal qualified-overtime cap.
