FAQ

What’s the difference between a C-Corp and an LLC in South Carolina?

C-Corporations offer unlimited growth potential, easy transfer of ownership, and established corporate structure attractive to investors. However, they face double taxation and more complex compliance requirements. LLCs provide tax flexibility, simpler operations, and pass-through taxation, but have restrictions on ownership types and may be less attractive to investors seeking traditional corporate structure.

How long does it take to form a C-Corporation in South Carolina?

Processing times vary depending on filing method and Secretary of State workload. Contact the South Carolina Secretary of State for current processing times. Online filings typically process faster than mailed paper forms. Expedited processing may be available for an additional fee.

Can I be the only shareholder and director of my South Carolina C-Corp?

Yes, South Carolina allows single-person corporations. You can serve as the sole shareholder, director, and officer. However, you must still follow all corporate formalities, including holding annual meetings, maintaining corporate minutes, and keeping business finances separate from personal accounts.

Do I need an attorney to form a C-Corporation in South Carolina?

While not legally required, consulting an attorney is advisable for complex business structures or if you’re unfamiliar with corporate law. An attorney can help with bylaws, stock agreements, and ensuring compliance with securities laws. For simple corporations, many business owners successfully file using online resources or formation services.

What happens if I don’t file annual reports or pay taxes?

Failure to file required annual reports can result in administrative dissolution of your corporation. Tax delinquencies lead to penalties, interest, and potential legal action. The South Carolina Secretary of State may also revoke your corporate charter for non-compliance. Always maintain current filings to preserve your corporation’s good standing.

Can I change my corporate name after incorporation?

Yes, you can change your corporate name by filing Articles of Amendment with the South Carolina Secretary of State. The new name must be available and comply with naming requirements. You’ll need to update your EIN, bank accounts, licenses, and contracts to reflect the name change.

What records must I maintain for my South Carolina C-Corporation?

Maintain corporate bylaws, shareholder and director meeting minutes, stock certificates and transfer ledgers, financial records, tax returns, and official correspondence. Keep these records at your principal office or registered agent’s address. Proper record-keeping protects your limited liability status and demonstrates corporate legitimacy.
