Choose Your Business Structure in South Carolina
Most founders in South Carolina choose an LLC because it combines liability protection with pass-through taxation. Filing an LLC costs $110 at the South Carolina Secretary of State online portal.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. Each has different liability exposure, tax treatment, and compliance requirements. See the full comparison below, or read our South Carolina LLC guide for a deeper walkthrough.

Business Structure Comparison — South Carolina
Full comparison guide| Structure | South Carolina Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | Free / No State Filing | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $110 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$110 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $110 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in South Carolina pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full South Carolina LLC guide →
