Ohio Business Entity Types
Ohio recognizes all standard US business entity types. Whether you're starting a manufacturing company or a professional services firm, the right structure depends on your liability protection needs, tax treatment, and growth plans. Here are the entity types you'll find when searching Ohio business records:
- Limited Liability Company (LLC): The most popular entity type for new Ohio businesses. The Ohio LLC filing fee is $99. LLCs offer personal liability protection with pass-through taxation and minimal compliance requirements. Since Ohio doesn't require annual reports, ongoing maintenance is especially light.
- Corporation (C-Corp / S-Corp): C-Corps are taxed at the entity level and are the standard structure for venture-backed startups and companies planning to issue stock or go public. S-Corps elect pass-through taxation but are limited to 100 shareholders. Filing fee: $99.
- Limited Partnership (LP): A partnership with one or more general partners (who manage the business and bear unlimited liability) and limited partners (who invest but have limited liability). LPs are common in Ohio's financial sector, especially real estate, private equity, and investment fund structures.
- Limited Liability Partnership (LLP): Used primarily by professional service firms such as law, accounting, medicine, and architecture practices. In an LLP, all partners have limited liability for the firm's debts and the actions of other partners. LLPs are common in Ohio's healthcare sector.
- Nonprofit Corporation: Organized for charitable, educational, religious, or scientific purposes. Eligible for federal tax-exempt status under IRC Section 501(c)(3) after IRS approval. Ohio nonprofits file with the Ohio Secretary of State and must comply with state-specific reporting requirements.
