Estimate your 2026 Ohio state income tax using your Ohio taxable nonbusiness income.
If income ≤ $26,050: Ohio tax = $0
If income > $26,050: Ohio tax = (Income − $26,050) × 2.75%
The 2026 Ohio rate and threshold are supported by current 2026 tax information.
Important: Ohio’s business-income rules are different, so I have deliberately described this calculator as a simplified nonbusiness/state income-tax estimator rather than pretending it calculates every Ohio taxpayer’s final liability. Ohio’s 2026 legislation retained separate treatment for business income.
If you want to estimate your Ohio state income tax for 2026, our 2026 Ohio Income Tax Calculator provides a simple way to estimate the state income tax based on your Ohio taxable income.
Ohio’s individual income tax rules changed for 2026. Effective January 1, 2026, a 2.75% flat personal income tax rate applies to income above $26,050 under the new structure. Income at or below $26,050 is not subject to the state individual income tax under this basic calculation.
The calculator on this page is designed to make the basic calculation easier to understand. It is an educational estimate and does not attempt to reproduce every part of an official Ohio tax return.
Important: This calculator is for general informational and educational purposes. It is not an official Ohio tax filing tool, tax advice, or a guarantee of your final tax liability.
The 2026 Ohio Income Tax Calculator is a simple online tool that estimates Ohio state individual income tax using taxable income.
Instead of calculating it manually, you can enter your income and let the calculator estimate the amount using the 2026 state rate and threshold.
The calculator can be useful if you want to:
Treat the result as an estimate, not an official tax determination.
Ohio changed its individual income tax structure for 2026.
Under the new structure, a 2.75% flat rate applies to nonbusiness income above $26,050. This replaced the previous multi-rate structure for the income covered by the new law.
This means that older Ohio income-tax calculators may not be appropriate for a 2026 estimate.
A calculator designed for an earlier tax year could use previous brackets or rates. When estimating taxes, choose the calculator for the correct tax year.
The 2026 Ohio calculation used on this page is based on the current 2026 rate and threshold.
For the simplified calculation used by this calculator, the 2026 Ohio state income tax rate is
2.75%
However, this does not mean that you multiply your entire income by 2.75%.
The $26,050 threshold is important.
The basic calculation is
Ohio Tax = (Ohio Taxable Income − $26,050) × 2.75%
when taxable income is above $26,050.
If taxable income is $26,050 or less, the basic state tax estimate is $0.
Using the calculator is straightforward.
Enter the amount of Ohio taxable income into the calculator.
Do not automatically assume that your gross salary is the same as your taxable income.
For example, someone may have a salary of $60,000 but a different taxable-income amount after applicable tax adjustments.
If you are preparing an actual tax return, use the appropriate figure from your tax documents or Ohio tax instructions.
The calculator includes a filing-status field for reference.
You can select:
The simplified calculation does not use this selection to change the state-tax formula.
This is intentional. The calculator does not attempt to calculate all filing-status-specific credits, exemptions, deductions, or other adjustments.
After entering your income, click Calculate Ohio Tax.
The calculator displays:
You can also calculate the basic 2026 estimate without a calculator.
The process has two steps.
Take your Ohio taxable income and subtract $26,050.
The formula is
(Ohio Taxable Income − $26,050) × 0.0275
If the result is zero or negative, the simplified state tax is $0.
Suppose your Ohio taxable income is
$20,000
Because $20,000 is below the $26,050 threshold, the simplified calculation gives:
Estimated Ohio state income tax = $0
Suppose your Ohio taxable income is
$30,000
First:
$30,000 − $26,050 = $3,950
Then:
$3,950 × 0.0275 = $108.625
Rounded to cents:
Estimated Ohio state tax = $108.63
Suppose your Ohio taxable income is
$50,000
Subtract the threshold:
$50,000 − $26,050 = $23,950
Then:
$23,950 × 0.0275 = $658.625
Rounded:
Estimated Ohio state income tax = $658.63
This example shows why you should not simply multiply the entire $50,000 by 2.75%.
The calculation applies the rate to the amount above the threshold.
For taxable income of $75,000:
$75,000 − $26,050 = $48,950
Then:
$48,950 × 0.0275 = $1,346.125
Estimated state tax:
$1,346.13
For $100,000 of Ohio taxable income:
$100,000 − $26,050 = $73,950
Then:
$73,950 × 0.0275 = $2,033.625
Estimated Ohio state income tax:
$2,033.63
These examples are based on the simplified state income tax formula the calculator uses.
Ohio taxable income is not necessarily the same thing as your gross income or annual salary.
For example, someone earning $70,000 in wages should not automatically assume that $70,000 is the correct number for every Ohio tax calculation.
Tax returns can involve different types of income and adjustments.
For that reason, the calculator asks for Ohio taxable income rather than salary.
If you are using the tool for general planning, you can enter the taxable-income figure you are working with.
If you are preparing an actual return, use the appropriate figure from your tax documents and current Ohio instructions.
No.
This calculator estimates Ohio state income tax only.
It does not calculate:
Federal and state income taxes are separate systems.
Therefore, do not interpret the result as the total amount deducted from a paycheck.
No.
Municipal income taxes are separate from the simplified state calculation.
Ohio provides The Finder, an official tool you can use to identify tax jurisdictions and local tax information based on an address or other search options.
This matters because local tax obligations can vary depending on where you live or work.
Ohio Department of Taxation — The Finder
Some Ohio school districts have an income tax.
The rate and applicable tax base can depend on the school district.
The Ohio Department of Taxation provides school-district information through The Finder, including tools for looking up school-district income-tax information.
Because school-district tax is separate from the simplified state calculation, it is not included in the calculator above.
This calculator provides a clear estimate of the basic Ohio state individual income tax.
Adding every possible municipal and school-district rule would require location-specific information and additional calculations.
Ohio’s official The Finder allows users to search local tax information by address, ZIP code, or other location methods.
For an estimate of your complete state and local tax situation, you should therefore check your applicable jurisdiction separately.
No.
This is an important limitation.
Ohio’s 2026 legislation has separate rules concerning business income. The 2.75% calculation used here is intended as a simplified estimate for the income covered by the personal/nonbusiness calculation. Do not simply substitute Ohio’s business-income treatment into this calculator.
If your tax situation includes significant business income, use the appropriate Ohio tax instructions or obtain professional tax guidance.
The effective tax rate is the estimated tax divided by total taxable income.
For example, suppose taxable income is $50,000, and the estimated Ohio tax is $658.63.
The effective rate is approximately
$658.63 ÷ $50,000 × 100 = 1.32%
This is lower than 2.75% because the simplified calculation does not apply the 2.75% rate to the first $26,050.
The 2.75% figure applies to the amount above the threshold, while the effective rate considers the entire taxable-income amount.
An online calculator result may differ from the final amount on your Ohio tax return.
Possible reasons include:
This is why you should use the calculator as an educational starting point, not a replacement for an official tax return.
The calculator uses the stated 2026 simplified formula:
0% through $26,050 and 2.75% on the amount above $26,050
for the income covered by this calculation. The 2026 rate and threshold are supported by current Ohio tax-law reporting.
However, “accurate” does not mean that the calculator can determine every taxpayer’s final liability.
A complete Ohio tax calculation can require additional information that this simple tool does not collect.
Tax rules can change.
A calculator created for 2024 or 2025 may use different tax rates and brackets.
Ohio’s 2026 rules introduced a flat 2.75% rate above the $26,050 threshold for the income covered by the new structure.
Therefore, always make sure that an online calculator clearly identifies the tax year it is designed for.
For the simplified calculation used here, the Ohio individual income tax rate is 2.75% on income above $26,050.
Under this simplified calculation, income of $26,050 or less is estimated at a 0% state individual income tax rate.
Using the simplified formula:
($50,000 − $26,050) × 2.75% = $658.63
This excludes other possible taxes and adjustments.
Yes. Municipal income taxes can apply, and Ohio provides The Finder to help identify applicable local tax information.
Some Ohio school districts impose an income tax. You can check the applicable information using the Ohio Department of Taxation’s The Finder.
No. The calculator only estimates Ohio state income tax.
The filing status is displayed for reference, but it does not change this simplified formula.
A complete tax return can involve additional factors related to filing status.
Not as a complete business-income tax calculation. Ohio has separate rules for business income, so don’t use this calculator as a substitute for those calculations.
No. It is an independent educational calculator.
For official information, use the Ohio Department of Taxation and its current tax resources.
No. A refund depends on factors such as tax liability, withholding, estimated payments, credits, and other information that this calculator does not collect.
Use the official Ohio Department of Taxation Finder to search for municipal and school district tax information.
The 2026 Ohio Income Tax Calculator provides a quick way to estimate Ohio state individual income tax using Ohio taxable income.
For the simplified calculation, income up to $26,050 is estimated at 0%, while the amount above $26,050 is calculated at 2.75%.
For example, someone with $50,000 of taxable income would have a simplified estimated Ohio state tax of approximately $658.63.
However, this is not necessarily the person’s complete Ohio tax liability. Municipal taxes, school-district taxes, business income, credits, exemptions, deductions, and other factors can affect the final result.
For location-specific Ohio taxes, The Finder can help identify applicable municipal and school district information.
