Notes

  • Kentucky levies a single flat rate of 4.0% (2025) on Kentucky taxable income — no brackets, same rate for every filing status and income level.
  • The flat rate is being ratcheted down 0.5 points at a time when revenue triggers are met: 4.5% (2023) → 4.0% (2024–2025) → 3.5% (2026, set by 2025 HB 1).
  • Kentucky standard deduction is a flat $3,270 (2025), inflation-indexed and the same for every filing status (KRS 141.081).
  • Kentucky itemized deductions (Schedule A) allow only home mortgage interest, investment interest, charitable contributions, and minor 'other' items — there is NO taxes-paid section, so property tax and state/local income tax are NOT deductible.
  • Kentucky starts from FEDERAL AGI and conforms to the federal pre-tax 401(k) and HSA treatment, so its taxable income begins at federal AGI with no add-backs.
  • Not modelled: Kentucky's Family Size Tax Credit (a low-income credit phasing out above ~133% of the federal poverty line) and other credits, because the shared input lacks the fields they require.
