  • No state income tax — nothing to conform — the federal deduction is your whole benefit
  • Rolling conformity — the federal deduction generally flows through to your state return
  • Fixed-date conformity — likely no state benefit until the state advances its date
  • Selective / hybrid — does not carry over automatically — confirm with the state

The short answer

The federal deduction is above-the-line, so it lowers your federal AGI whether or not you itemize. States split three ways: no income tax (nothing more to consider), rolling conformity (the deduction generally flows through), and fixed-date or selective conformity (a brand-new 2025 provision usually does not reach your state return until the state updates). Your state's page says which it is and who to confirm with.
