If you own a business in Ohio—or are considering starting one—there’s good news. Ohio continues to offer one of the most favorable tax environments for business owners, particularly those operating pass-through entities such as LLCs, S corporations, partnerships, and sole proprietorships.
Here’s a quick overview of how Ohio business taxes work for the 2026 tax year.
Significant Tax Benefits for Pass-Through Businesses
Most small and mid-sized businesses are organized as pass-through entities, meaning business profits are reported directly on the owner’s individual tax return rather than being taxed at the business level. These provisions can significantly reduce the state tax burden for many Ohio business owners.
Ohio provides several valuable tax advantages for these businesses:
- 100% business income deduction (BID): The first $250,000 of qualifying pass-through business income is completely tax-free for single filers and married couples filing jointly. For married individuals filing separately, the deduction is limited to $125,000.
- Low tax rate above the threshold: Eligible business income exceeding $250,000 is taxed at a flat 3% rate.
- Electing pass-through entity (PTE) tax: Beginning with reporting periods starting in 2026, electing pass-through entities that file Ohio Form IT 4738 will pay a flat 3% tax.
- S Corp owners salaries are not taxable: Your S Corp salary is considered “business income” and subject to the Business Income Deduction (BID) mentioned above.
Commercial Activity Tax (CAT)
Ohio does not impose a traditional corporate income tax. Instead, larger businesses may be subject to the Commercial Activity Tax (CAT), which is based on gross receipts rather than net income. For 2026:
- Businesses with $6 million or less in taxable Ohio gross receipts owe no CAT.
- Gross receipts exceeding $6 million are taxed at a flat 0.26% rate.
- The annual minimum CAT has been completely eliminated, reducing compliance costs for many businesses.
What About Personal Income?
If you receive W-2 wages or have other non-business income, Ohio now uses a simplified individual income tax system. For the 2026 tax year, the first $26,050 of taxable non-business income is taxed at 0%. Income above that amount is taxed at a flat 2.75% rate. This streamlined structure makes Ohio’s individual income tax easier to understand while maintaining relatively low tax rates.
