What this means for Iowa workers

This state uses federal AGI as the starting point for state taxable income, with rolling conformity to the IRC. Because the qualified-tips and qualified-overtime deductions are above-the-line federal deductions, they reduce federal AGI — and that reduction passes through to state taxable income automatically. Workers do not need to take any extra step at the state level.

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.
