Notes

  • Idaho levies a single flat 5.3% individual income tax rate for 2025; House Bill 40 (signed March 6, 2025) cut the rate from 5.695% to 5.3% effective for the 2025 tax year.
  • Idaho applies a 0% zero-rate bracket before the flat rate: the first $4,811 of Idaho taxable income (single / married filing separately) or $9,622 (married filing jointly / head of household) is taxed at 0%.
  • Idaho's standard deduction equals the federal standard deduction for the year, so it tracks the federal amount automatically; Idaho Form 40 starts from federal taxable income.
  • Not modelled: Idaho-specific additions and subtractions (e.g. the state-income-tax addback on itemized deductions, retirement-benefit and capital-gains deductions) on Form 39R, which the shared input cannot capture.
