Notes

  • Indiana levies a single flat STATE rate of 3.00% (2025) on Indiana taxable income — no brackets, same rate for every filing status and income level. The statutory step-down is 3.05% (2024) -> 3.00% (2025) -> 2.95% (2026).
  • County local income tax (LIT) is separate and set by each county (roughly 0.5%-3%+). There is no county field in the shared input, so the county rate is an OPTIONAL parameter; when supplied it is returned as localTax (computed on the same Indiana taxable income, Schedule CT-40), otherwise localTax is omitted.
  • The tax base is FEDERAL AGI; Indiana has no standard or itemized deduction — it subtracts flat exemptions instead.
  • Personal exemption: $1,000 for the taxpayer plus $1,000 for a spouse on a joint return ($2,000 married filing jointly; $1,000 otherwise).
  • Dependent exemption: a flat $1,000 per dependent (IT-40 Schedule IN-DEP).
  • Not modelled (no data in the shared input): the additional $1,500 qualifying-dependent-CHILD exemption, the $1,000 age-65+/blind exemptions, the extra $500 low-income age-65+ exemption, and Indiana-specific add-backs/subtractions.
