Ohio Income Tax Rate for 2026

Examples

Ohio Income Tax Calculation Examples

The goal of these examples is to compare Single and Married Filing Jointly statuses at the same $80,000 annual income per person. The Single example uses $80,000 of household income, while the Married Filing Jointly example assumes each spouse earns $80,000, for a combined $160,000. The results match our All 50 States income tax calculator using $80,000 or $160,000 and the corresponding filing status.

To simplify the calculations, both examples assume full-year Ohio residency, W-2 wages only, no dependents, and taxpayers under age 65 who are not blind or claimed as dependents. Ohio starts with federal adjusted gross income and does not have a standard deduction. The federal standard deduction does not reduce Ohio taxable income either. These examples apply personal exemptions and, in the Married Filing Jointly example, the joint filing credit. No other deductions, Ohio additions or subtractions, or tax credits are included. Local income taxes are excluded. See the All 50 States calculator for a full list of assumptions and sources.

Ohio's personal exemption per person decreases at higher levels of modified adjusted gross income, which equals household wages in these examples. The Single filer earning $80,000 qualifies for a $2,150 exemption. The married couple's higher combined income of $160,000 reduces the exemption to $1,900 per spouse, or $3,800 combined. These amounts appear in Ohio's 2025 instructions and remain applicable for 2026 because House Bill 96 suspended inflation adjustments.

Looking at the table above, we can see that the same 2.75% statutory rate applies to both Single and Married Filing Jointly statuses. The personal exemption does not double because the joint household's higher income reduces the exemption per person. Ohio also uses the same $26,050 threshold and $332 base amount for each return. The joint filing credit reduces the married couple's tax, but it does not fully offset these differences. Before rounding, the joint tax is about $203 higher than the combined tax of two single filers who each earn $80,000. This simplified comparison therefore shows an Ohio marriage penalty. Next, we will review the step-by-step calculations for each filing status.

Step-by-Step Example 1: Single

For a single filer with $80,000 of household income, the Ohio personal exemption is $2,150. With wages only and no other adjustments, subtracting the exemption leaves $77,850 of taxable income. Because this exceeds $26,050, the calculation uses the $332 base amount plus 2.75% of the income above that threshold.

• Taxable income: Subtract the personal exemption from household income. $\mathrm{\$80,000}-\mathrm{\$2,150}=\mathrm{\$77,850}$
• Income above the threshold: Subtract $26,050 from taxable income. $\mathrm{\$77,850}-\mathrm{\$26,050}=\mathrm{\$51,800}$
• Estimated Ohio income tax: Multiply the excess by 2.75%, then add the $332 base amount. $\mathrm{\$51,800}\times 0.0275+\mathrm{\$332}=\mathrm{\$1,756.50}$

Ohio effective tax rate: $1,756.50 divided by $80,000 of household income equals 2.20%, rounded. The estimated state income tax rounds to $1,757 in the comparison table.

Ohio marginal tax rate: 2.75%, the statutory rate applied to each additional dollar above the threshold before credits. Changes in exemption eligibility can also affect the tax amount.

Step-by-Step Example 2: Married Filing Jointly

Now let's apply the same calculation to a married couple filing jointly. Each spouse earns $80,000 with a combined household income of $160,000. The personal exemption is $1,900 for each spouse, or $3,800 combined. Both spouses have enough qualifying wages for the joint filing credit. At this income level, the credit is 5% of the tax before the credit, up to a maximum of $650.

• Taxable income: Subtract the combined personal exemptions from household income. $\mathrm{\$160,000}-\mathrm{\$3,800}=\mathrm{\$156,200}$
• Income above the threshold: Subtract the same $26,050 threshold used for Single. $\mathrm{\$156,200}-\mathrm{\$26,050}=\mathrm{\$130,150}$
• Ohio income tax before credits: Multiply the excess by 2.75%, then add the $332 base amount. $\mathrm{\$130,150}\times 0.0275+\mathrm{\$332}=\mathrm{\$3,911.13}$
• Joint filing credit: Multiply the tax before credits by 5%. $\mathrm{\$3,911.13}\times 0.05=\mathrm{\$195.56}$
• Estimated Ohio income tax: Subtract the joint filing credit. $\mathrm{\$3,911.13}-\mathrm{\$195.56}=\mathrm{\$3,715.57}$

Ohio effective tax rate: $3,715.57 divided by $160,000 of household income equals 2.32%, rounded. The estimated state income tax rounds to $3,716 in the comparison table.

Ohio marginal tax rate: 2.75%, the same statutory rate used for Single before applying the joint filing credit.

Takeaway

Ohio Income Tax Takeaways

A flat rate still requires more than one calculation: Ohio's 2.75% rate is applied through a formula that includes a $26,050 threshold and a $332 base amount. Personal exemptions reduce taxable income, and eligible credits reduce the tax itself.

Equal income per person can produce different tax per person: The joint household receives a smaller exemption per spouse and uses the same threshold as the Single filer. Even after the joint filing credit, the joint tax is about $203 higher than two Single taxes before rounding. This example shows a marriage penalty despite the same statutory rate.

The effective rate reflects the final state tax estimate: The Single example produces a 2.20% effective rate, compared with 2.32% for Married Filing Jointly. Both are below the 2.75% statutory marginal rate. Results can differ when income, exemptions, state adjustments, or credits change. Municipal and school district income taxes, when applicable, are additional.
