Notes

  • Louisiana switched to a single flat 3% individual income tax rate for 2025; Act 11 of the 2024 Third Extraordinary Session repealed the old graduated schedule (1.85% / 3.5% / 4.25% for 2022–2024).
  • The 2025 standard deduction was nearly tripled to $12,500 (single / married filing separately) and $25,000 (married filing jointly / head of household / qualifying surviving spouse); these amounts are CPI-indexed starting January 1, 2026.
  • The deduction for federal income taxes paid is REPEALED for individuals (removed since 2022 by constitutional Amendment 2, and still gone under the 2025 reform); the 2025 IT-540 goes Federal AGI → standard deduction → taxable income with no federal-tax deduction step.
  • Act 11 also repealed the per-dependent, over-65, and blind personal exemptions, so — unlike Illinois — there is no per-person exemption to subtract.
  • Louisiana starts from federal AGI and conforms to the federal pre-tax 401(k) / HSA treatment, so there are no add-backs.
  • Not modelled: the narrowed 'excess federal itemized deductions' (IT-540 Lines 9A–9D, now keyed to federal Schedule A medical/dental expenses exceeding the federal standard deduction) and the $12,000 retirement-income exemption for filers aged 65+, since the shared input cannot capture federal Schedule A detail or taxpayer age. This module applies the standard deduction only.
