Kentucky vs Ohio taxes

Where the difference comes from

Neither state deducts a payroll levy, so the state-level difference is the two income taxes, and both are flat. Kentucky charges 3.5% after a standard deduction of $3,360, so it reaches almost the whole salary. Ohio charges 2.75%, and only on income above $26,050, after a personal exemption that steps down as income rises.

On $75,000 Kentucky takes $2,507 and Ohio $1,287, so a single filer keeps $1,220 more in Ohio before any local tax. Ohio’s untaxed first band is worth the most, relative to pay, at lower salaries: below $26,050 Ohio charges nothing, while Kentucky’s tax has already started.

Above that band, Kentucky’s rate is three quarters of a point higher, so the gap keeps widening slowly: $1,033 on $50,000, $1,776 on $150,000 and $2,526 on $250,000. Ohio stays ahead at every salary.

The local taxes are bigger than the state gap

Both columns leave out local taxes, and here they can matter more than the state difference.

Ohio cities. Most levy their own income tax. Columbus, Cleveland, Cincinnati and Toledo are all around 2% to 2.5%, charged where you live and where you work, with credits between some cities so the two do not simply stack. Some Ohio school districts levy an income tax as well. A 2.5% city tax on $75,000 is $1,875, more than Ohio’s state tax at that salary.

Kentucky counties and cities. Most levy an occupational license tax on wages, charged where you work. Louisville is around 2.2% and Lexington around 2.25%, which on $75,000 comes to roughly $1,650 to $1,688.

So the Ohio advantage above is the state share only. Whether you come out ahead overall depends on the city you live in and the one you work in, and a move between two particular places can turn the state figure around.

Reciprocity: the state tax follows your home

Cincinnati’s metro area spans the river, and the two states have a reciprocal agreement. The Kentucky Department of Revenue’s instructions for Form 740-NP list Ohio among its reciprocal states for wages and salaries, under agreements that tax people “by their state of residence, and not the state where income is earned”. It does not apply to anyone who lives in Kentucky for more than 183 days of the year, who is treated as a resident.

For a commuter that means:

• Live in Kentucky, work in Ohio: Kentucky taxes the wages at its rate. The Ohio state figure does not apply to you, but the city income tax where you work does.
• Live in Ohio, work in Kentucky: Ohio taxes the wages at its lower rate, and the Kentucky occupational tax where you work still applies.

So for the same job, living on the Ohio side saves the state gap shown above, and the local taxes depend on the particular city and county at each end of the commute.

What else the figures leave out

Neither state taxes Social Security. Kentucky exempts a set amount of pension income per person, and Ohio offers a retirement income credit; this page models wages only. Kentucky’s joint return also gives a couple the same deduction as one single person, which is why many Kentucky couples file separately at state level. Property and sales taxes are not in these figures.

Questions people ask

Do you take home more in Kentucky or Ohio on $75,000?

Ohio, by $1,220 a year, or $102 a month, for a single filer in 2026. That counts federal tax, Social Security, Medicare, state income tax and every state payroll deduction.

Is the difference the same at every salary?

No, but the same side stays ahead. The gap is $890 a year at $30,000 and $2,526 at $250,000, for a single filer.

I live in Northern Kentucky and work in Cincinnati. Which state taxes my wages?

Kentucky. Under the reciprocal agreement between the two states, wages and salaries are taxed by the state you live in, not the one you work in, so you pay Kentucky's rate on them. Cincinnati's own city income tax is a separate matter and still applies to work done in the city.

Does reciprocity cover everything I earn in the other state?

No. It covers pay as an employee. Business income, rental income from property in the other state and gambling winnings are taxed where they arise, and so is the pay of someone who owns a large share of the business paying them.

Do both states have local income taxes?

Yes, and neither is in the figures above. Most Ohio cities levy an income tax, and some school districts do too. Most Kentucky counties and cities levy an occupational license tax on wages. Rates and rules differ from place to place, so there is no statewide figure to apply.

What this comparison covers

Income tax and payroll deductions on wages: federal income tax, Social Security, Medicare, state income tax, every state payroll deduction. It does not compare sales tax, property tax, housing or the cost of living, which can outweigh the difference in take-home pay. Figures assume the standard deduction, no dependents and no pre-tax retirement contributions. See how we calculate.
