Flat rate

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). / 印第安纳州对州应税收入征收 3.00%(2025 年)的单一统一州税率——没有累进税档,所有报税身份和收入水平税率相同。法定逐年下调:3.05%(2024 年)→ 3.00%(2025 年)→ 2.95%(2026 年)。
  • 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. / 县级地方所得税(LIT)单独征收,由各县自行设定(约 0.5%–3% 以上)。共享输入中没有县字段,因此县税率为可选参数;提供时作为 localTax 返回(按相同的印第安纳州应税收入计算,CT-40 附表),否则省略 localTax。
  • The tax base is FEDERAL AGI; Indiana has no standard or itemized deduction — it subtracts flat exemptions instead. / 计税基数是联邦 AGI;印第安纳州没有标准扣除额或分项扣除额——而是减去固定豁免额。
  • 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). / 个人豁免:纳税人 1,000 美元,联合申报的配偶再加 1,000 美元(联合申报 2,000 美元;其他身份 1,000 美元)。
  • Dependent exemption: a flat $1,000 per dependent (IT-40 Schedule IN-DEP). / 受抚养人豁免:每名受抚养人统一 1,000 美元(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. / 未建模(共享输入中无相应数据):额外的 1,500 美元符合条件的受抚养子女豁免、1,000 美元的 65 岁以上/失明豁免、额外的 500 美元低收入 65 岁以上豁免,以及印第安纳州特有的加回项/减除项。
