Ohio Income Tax for Business Owners: 2026 Rates, Flat 3% Business Rate and the Deduction
Ohio Income Tax for Business Owners: 2026 Rates, Flat 3% Business Rate and the Deduction
If you own a business in Ohio, the state income tax question usually comes down to two things: how much of your business profit is taxed, and at what rate. For tax years 2026 and later, Ohio splits the answer. Non-business income, such as wages, interest and investment income, follows a schedule that starts at 0%. Taxable business income is taxed at a flat 3% after a deduction of the first $250,000 per individual. This guide explains the 2026 Ohio income tax rate structure, how the Ohio business income deduction works, and what Ohio does and does not tax at the business level.
This guide is informational only. It is not legal or tax advice. Your result depends on your entity type, income, filing status and where you live. Confirm current figures with the Ohio Department of Taxation at tax.ohio.gov, and talk to a qualified CPA before you file or make any election.
How Ohio taxes business owners: the short version
Ohio does not levy a corporate income tax. Corporations pay the Commercial Activity Tax (CAT) instead, which is a gross receipts tax and is covered below. Individuals pay the personal income tax, and that is where the business income rules apply. Sole proprietors, partners, and owners of pass-through businesses such as many LLCs and S corporations generally report their share of business profit on their individual Ohio return.
That means most small business owners in Ohio do not file a separate state income return for the business itself. The business profit flows onto the owner's personal return, and the owner's total tax reflects both the business piece and the personal piece.
2026 Ohio income tax rates for individuals
House Bill 96, signed June 30, 2025, sets the individual rates for tax year 2026 and after under Ohio Revised Code 5747.02. Three rules matter most to business owners:
| Income type | Tax year 2026 treatment |
|---|---|
| Non-business income up to $26,050 | 0% |
| Non-business income above $26,050 | $332 plus 2.75% of the excess over $26,050 |
| Taxable business income | Flat 3%, after the business income deduction |
For 2026 the graduated brackets from 2025 collapse into a single bracket: $332 plus 2.75% of the excess over $26,050. For comparison, the 2025 schedule was 0% on the first $26,050, $342 plus 2.75% of the excess over $26,050, and $2,394.32 plus 3.125% of the excess over $100,000. Bracket inflation indexing is suspended for 2025 and 2026, so the thresholds will not rise automatically.
Confirm the current schedule with the Ohio Department of Taxation before you run your numbers, because the base amount and rate change your estimate.
The flat 3% business income rate
Taxable business income is taxed at a flat 3%. This is the rate behind most searches for the Ohio business income tax. It is a single rate, so a larger business profit does not push the business portion into a higher bracket. Business income is kept separate from non-business income when Ohio figures your tax, which is why the two rates do not blend together.
If you have both a salary from a job and profit from your own business, the two streams are taxed under different rules. Ask a CPA to confirm how each item is classified, especially for unusual income such as rental activity, royalties or one-time sales of business assets.
The business income deduction: the first $250,000
The Ohio business income deduction is set by Ohio Revised Code 5747.01(A)(28). Each individual can deduct the first $250,000 of business income. Only business income above that amount is taxed at 3%. Married individuals who file separately each get a $125,000 deduction.
The deduction is applied per individual, so profit split among several owners is measured owner by owner. Confirm how this applies to your ownership structure with a CPA before you assume the full $250,000 is available to each owner.
| Net business income (one individual) | Deduction | Taxable business income | Tax at 3% |
|---|---|---|---|
| $200,000 | $200,000 | $0 | $0 |
| $400,000 | $250,000 | $150,000 | $4,500 |
| $600,000 | $250,000 | $350,000 | $10,500 |
The table is simplified. It ignores personal exemptions, the owner's non-business income, credits, and any city or school district income tax. It shows the mechanics: the first $250,000 is removed, and only the rest is taxed at 3%.
Who claims the deduction
The business income deduction is claimed on the individual return. If your business is a pass-through entity that elects to pay Ohio tax at the entity level, the entity does not claim the deduction for you. The owner still claims it on their individual return. Confirm the election rules, deadlines and reporting steps with the Ohio Department of Taxation before you make an election, because the choice changes where the tax is paid and how the deduction is reported.
Personal exemptions reduce taxable income
Ohio personal exemptions reduce taxable income under Ohio Revised Code 5747.025. Exemption amounts and eligibility rules can change, so check the current figure with the Ohio Department of Taxation rather than relying on an older guide. Because exemptions come off before tax is figured, your final state tax can be lower than a simple 3% or 2.75% calculation would suggest.
What “Ohio flat tax” actually means
People searching for the Ohio flat tax are usually asking about two different things, and the answer differs for each. The business piece is flat: 3% on taxable business income above the $250,000 deduction. The personal piece is nearly flat: 0% on the first $26,050 of non-business income, then $332 plus 2.75% of the excess. Ohio does not apply one rate to every dollar you earn, and it does not use a multi-bracket schedule for tax year 2026.
For planning, the practical result is that a business owner with moderate profit pays the business rate on a small slice, while a larger profit mostly escapes tax on the first $250,000 per owner. Your personal non-business income still follows the personal schedule separately.
City and school district income taxes are separate
State income tax is only part of the picture. Many Ohio cities and villages levy their own income tax, and some school districts do too. Cities and villages tax business net profit under their own rates, so two businesses with the same profit can owe different local amounts depending on where they operate. Local rates, filing deadlines and forms are set by each jurisdiction. Check with your city or village tax office and your school district before you estimate your total Ohio tax bill.
Commercial Activity Tax: a gross receipts tax, not an income tax
The Commercial Activity Tax is often confused with the income tax, but it works differently. The CAT is a gross receipts tax of 0.26% (.0026) on Ohio taxable gross receipts. For tax year 2025 and later, only businesses with more than $6 million of Ohio taxable gross receipts owe the CAT or must register. Businesses above that line file CAT returns quarterly.
Ohio has no franchise tax and no annual tax for LLCs. Financial institutions pay the Financial Institutions Tax instead of the CAT, and insurance companies pay the insurance premiums tax. If your business is below the $6 million exclusion, the CAT generally does not apply to you, but confirm your Ohio taxable gross receipts against the rules on the Ohio Department of Taxation site at tax.ohio.gov.
Other Ohio obligations that are not income tax
Readers often mix up state income tax with other filings. These are separate and should be tracked on their own:
- No LLC annual report. Ohio LLCs file no annual or biennial report.
- No general state business license. Ohio issues no single general state business license, and no statewide general contractor license. Counties issue no business license.
- Sales tax vendor's license. Every retailer selling taxable goods or services needs one before making taxable sales. The county auditor issues it under a state statute, and the application fee is $50 as of April 9, 2025. You can apply through the Ohio Business Gateway or the county auditor.
- Trade names. A trade or fictitious name is registered with the Ohio Secretary of State, not the county. The registration fee is $39 at ohiosos.gov.
- Workers' compensation. Coverage is purchased from the state BWC fund.
A checklist before you file
- Identify how your business is taxed: sole proprietorship, partnership, LLC, S corporation, or an entity that elected entity-level tax.
- Calculate net business income for each individual owner.
- Apply the $250,000 deduction, or $125,000 if you are married and filing separately.
- Calculate tax at 3% on the remaining business income.
- Calculate non-business income separately: 0% up to $26,050, then $332 plus 2.75% of the excess.
- Apply personal exemptions under Ohio Revised Code 5747.025.
- Check whether your city, village or school district levies income tax, and what rate and filing deadline applies.
- Confirm whether any entity-level election changes where the tax is paid or how the deduction is reported.
- Confirm whether your gross receipts put you above the $6 million CAT exclusion.
When to bring in a professional
Simple sole proprietorships with one owner and modest profit can often use the rules above directly. Get professional help if any of these apply: several owners share the profit, your business is an S corporation or has an entity-level tax election, your business income is near the $250,000 line, you are married and filing separately, you work or sell in more than one state or city, or you have rental, royalty or investment income alongside the business. A CPA can confirm your numbers, and a tax attorney can advise on entity structure.
