Ohio takes a unique approach to business taxation. The state eliminated its traditional corporate income tax in 2005, replacing it with the Commercial Activity Tax (CAT), a broad-based gross receipts tax. Additionally, Ohio imposes no corporate franchise tax. For pass-through entity owners, Ohio’s individual income tax features a Business Income Deduction that shelters the first ~$250,000 of qualifying business income from state tax. Ohio’s municipal income taxes add another layer of complexity, as many cities tax business net profits.

How Ohio Business Taxes Work
Commercial Activity Tax (CAT)
The CAT is Ohio’s primary business-level tax, replacing the corporate income tax and franchise tax. Key features:
- Base: Taxable gross receipts (revenue) from business activity in Ohio, regardless of profitability
- Rate: ~0.26% on receipts over ~$1 million
- Minimum Tax: Businesses with receipts between ~$150,000 and ~$1 million pay a minimum tax of ~$150
- No receipts-based threshold: Businesses under ~$150,000 in Ohio receipts are not subject to the CAT
- Situsing rules: Receipts are sourced to Ohio based on where the customer receives the benefit of the service or where goods are delivered
The CAT applies to all business entity types — C corporations, S corporations, partnerships, LLCs, and sole proprietorships with receipts above the threshold.
CAT Rate Schedule
| Annual Taxable Gross Receipts | CAT Due |
|---|---|
| Under ~$150,000 | ~$0 |
| ~$150,000 to ~$1,000,000 | ~$150 minimum |
| Over ~$1,000,000 | ~$150 + ~0.26% of receipts over ~$1,000,000 |
Business Income Deduction (BID)
Ohio’s individual income tax provides a significant benefit for pass-through business owners. The BID allows taxpayers to deduct the first ~$250,000 of qualifying business income from Ohio adjusted gross income. Income above ~$250,000 is taxed at a flat ~3.50%.
This deduction effectively makes the first ~$250,000 of pass-through business income state-tax-free for Ohio individual taxpayers, a substantial incentive for small and mid-size business owners.
Municipal Income Tax
Many Ohio cities and villages impose a municipal income tax on business net profits. Major city rates include:
| City | Municipal Tax Rate |
|---|---|
| Columbus | ~2.50% |
| Cleveland | ~2.50% |
| Cincinnati | ~2.10% |
| Dayton | ~2.50% |
| Toledo | ~2.50% |
| Akron | ~2.50% |
Municipal income taxes are based on net profits apportioned to each jurisdiction, and businesses operating in multiple Ohio cities may need to file returns in each.
Key Business Tax Obligations
| Obligation | Description | Filing Frequency |
|---|---|---|
| Commercial Activity Tax | ~0.26% on receipts over ~$1M | Quarterly/Annual |
| Individual income tax (pass-through) | ~0% to ~3.50% with BID | Annual |
| Sales tax | ~5.75% state + local | Monthly/Semi-annual |
| Municipal net profit tax | ~0% to ~3.0% by city | Annual (quarterly est.) |
| Withholding tax | Based on income brackets | Monthly/Quarterly |
| Unemployment insurance | ~0.3% to ~9.8% on first ~$9,000 | Quarterly |
Comparison to Neighboring States
| State | Primary Business Tax | Rate | Pass-Through Treatment |
|---|---|---|---|
| Ohio | CAT (gross receipts) | ~0.26% | BID: first ~$250K at ~0% |
| Pennsylvania | Corporate income tax | ~8.99% | ~3.07% flat individual |
| Indiana | Corporate income tax | ~4.9% | ~3.05% flat individual |
| Michigan | Corporate income tax | ~6.0% | ~4.05% flat individual |
| West Virginia | Corporate income tax | ~6.5% | ~3% to ~6.5% graduated |
| Kentucky | Corporate income tax | ~4.0% to ~5.0% | ~4.0% flat individual |
Ohio’s lack of a corporate income tax and its generous BID make it uniquely favorable for businesses, particularly small to mid-size pass-through entities. However, the CAT as a gross receipts tax means even unprofitable businesses owe tax if they have sufficient revenue.
Tips for Ohio Business Owners
- Maximize the Business Income Deduction — structure your business to ensure income qualifies as “business income” under Ohio’s definition to take advantage of the ~$250,000 deduction.
- Manage CAT liability by accurately sourcing receipts. The CAT is based on where the customer benefits, not where your operations are located.
- Plan for municipal taxes — if you operate in multiple Ohio cities, you may owe municipal net profit taxes in each. Credit mechanisms exist to avoid double taxation but require careful tracking.
- Consider the gross receipts nature of the CAT — unlike income taxes, the CAT applies regardless of profitability. Low-margin businesses may find the CAT burdensome relative to their net income.
- Evaluate entity structure with the BID in mind. Pass-through entity owners benefit from the ~$250,000 deduction, while C corporations do not. See the self-employment tax guide for federal implications.
- File CAT returns on time — quarterly filings are due by May 10, August 10, November 10, and February 10. Annual filers submit by May 10.
- Consult a professional for complex multi-city filing situations. See find a CPA near you.
