OVERVIEW
At the state level, Ohio is now considerably cheaper than Kentucky for most earners—its 0% rate on the first $26,050 plus a flat 2.75% rate above that (2026, per House Bill 96) saves a $100,000 earner roughly $1,401 per year compared to Kentucky’s flat 3.5%. Ohio’s local tax system is still unusually complex, though: most Ohio residents pay a city income tax (typically 2%–2.5%, e.g., Columbus 2.5%, Cleveland 2.5%) plus potentially a School District Income Tax. Adding those in narrows Ohio’s advantage but no longer erases it at most incomes, since Ohio’s new flat state rate is well below Kentucky’s 3.5%. Kentucky residents in Louisville or Lexington face their own 2.2%–2.25% occupational tax. Kentucky reduced its rate to 3.5% in 2026, while Ohio moved the other direction to a lower 2.75% flat rate—Ohio’s state-level advantage over Kentucky has widened, not narrowed.

FAQ

Frequently Asked Questions

Does Ohio’s lower state rate actually mean a lower total tax bill?

Not necessarily, though the math has shifted in Ohio’s favor since the 2026 flat-tax reform. Ohio’s state rate now saves $1,401 at $100,000 income compared to Kentucky (Ohio’s state rate dropped to a flat 2.75%, per House Bill 96), but most Ohio residents also pay a municipal income tax—Columbus and Cleveland both charge 2.5%—plus potentially a School District Income Tax of up to 2%. Add those together and an Ohio resident in Columbus pays roughly 2.75% (state) + 2.5% (city) ≈ 4.1% combined at $100,000, versus Kentucky’s flat 3.5%—Ohio can still come out higher in cities that also levy a school district tax, but the gap is narrower than it used to be. Always calculate total burden for the specific Ohio city you’re considering.

What is Kentucky’s income tax rate path going forward?

Kentucky enacted legislation to reduce its flat income tax rate in annual increments, contingent on revenue growth targets. The rate fell from 5% to 4.5% in 2023, then to 4.0% in 2024, then to 3.5% in 2026. Further reductions may follow if revenue conditions are met. Ohio, meanwhile, moved the opposite direction in 2026—House Bill 96 replaced its old graduated system (which topped out at 3.5%) with a single flat 2.75% rate above a $26,050 zero-bracket floor. As a result, Kentucky’s 3.5% flat rate is now clearly higher than Ohio’s 2.75% flat rate at the state level for most earners.

Is Louisville or Columbus a cheaper place to live?

Louisville and Columbus are both affordable mid-size cities. Louisville generally has a slightly lower cost of living, particularly housing. However, Columbus has a larger and faster-growing economy with more major employers and a strong university presence (Ohio State). Columbus residents should budget for the 2.5% city income tax, which does not apply in Louisville (though Louisville levies a 2.2% occupational tax on earnings).

How does Ohio treat retirement income?

Ohio does not tax Social Security benefits. For other retirement income, Ohio allows a retirement income credit for taxpayers aged 65+ with retirement income. The credit can offset up to $200 of tax owed. Kentucky taxes most retirement income but exempts the first $31,110 of pension/retirement income per person. For retirees with moderate income, both states offer some relief, though neither is as generous as states like Georgia or Florida.
