South Carolina single-member LLC remains one of the ideal business entities for small business entrepreneurs, online marketers, and freelance labor who seek limited liability protection, ease of management and tax benefits. As an independent consultant, small business employee, or freelance employee, creating a single-member LLC (SMLLC) in South Carolina provides flexibility, privacy, and an officially created business entity, albeit without corporate formalities.
This book offers an introduction to the main requirements and things to keep in mind in forming a one-person LLC in South Carolina, from operating agreements to tax reporting requirements.
South Carolina Single Member LLC: Benefits and Formation
A South Carolina single-member LLC is one in which there is only one owner, or "member." This type offers both personal liability protection of a corporation, as it provides ease of pass-through taxation, although it's best suited for solopreneurs who desire to have a business entity that's legally established without stringent governance laws.
Significant Pros:
- Limited liability protection: Personal property (such as your car or house) remains outside business responsibilities.
- Tax simplicity: The income and loss flow through to your personal income tax return automatically.
- Professional image: Adding "LLC" to one's name increases business believability.
- Flexible management: The company can be managed without involving the board or formalities' intricacies.
Formation Criteria:
To establish a South Carolina single-member LLC, the sole owner needs to:
- Choose an unusual business name and include "LLC" or "Limited Liability Company" in it.
- Register Articles of Organization with the Secretary of State of South Carolina.
- Regular pay of filing fee (subject to increase once every year).
- Appoint a registered agent whose office resides in South Carolina.
- Get a stamped Certificate of Formation to legitimately do business as an LLC.
Although an LLC may have one owner, it still must comply with state legal guidelines just as any other LLC.

Single Member LLC Operating Agreement in South Carolina
While it isn't necessary under South Carolina law to have an operating agreement in an LLC, it would be most recommended to have one, even in single-member LLCs.
A South Carolina single-member LLC operating agreement refers to an official document which describes how an LLC in South Carolina is run. It differentiates between the business and owner, and it reinforces liability protection as evidence that an LLC qualifies as an independent legal entity.
Critical Aspects in an Operating Agreement:
- Ownership statement: Confirms if an LLC is exclusively owned and controlled by one member.
- Business purpose: This clearly states the type of business you operate.
- Management structure: Indicates whether this business will be.
- Banking and financial protocols: It includes disbursements of profit and maintenance of accounts.
- Succession plan: Outlines what would occur in case of the owner's incapacity or death.
An operating agreement proves particularly valuable to banking, accounting, legal controversies, and financing or investor applications. Should this paperwork not exist, then it defaults to state laws, and these might not mirror how the owner wants to operate the business.

South Carolina Single Member LLC Filing Requirements
Once established, a South Carolina single-member LLC needs to remain in compliance with state statutes. It could face fines, dissolution, or loss of good standing due to missed filings or deadlines.
Important Filing Formalities:
- Annual Report: The South Carolina LLCs don't have to annually file an annual report, except in instances in which they're being taxed as an incorporated business.
- Maintenance of Registered Agent: The LLC needs to have a registered agent and inform the Secretary of State in case the agent or their address changes.
- Business License/Permit: It depends on your city or county, and you may be required to have a local business license. It is filed independently of your state filing.
- DBA or Trade Name: When an LLC does business under another name, it needs to be registered in the county as a DBA (Doing Business As).
That said, paperwork in an LLC in South Carolina is fairly low in comparison to other states, but staying current prevents potential administrative issues or fines unnecessarily.

In one of the most favorable aspects of an LLC, an LLC offers tax versatility. The single-member LLC in South Carolina would be considered to be disregarded for federal tax purposes, but it can choose to be treated as being taxed as a corporation.
How Taxation Works:

- Self-Employment Tax: The business owner owes self-employment tax on net earnings.
- State Income Tax: Personal income tax is paid in South Carolina, and the income of your LLC must be reported in your personal SC return.
- Sales Tax: In the event the LLC sells taxable goods or services, you will have to register for a South Carolina Sales Tax License and remit monthly or quarterly.
- Withholding Tax: If the LLC employs people, it will owe state employer tax and will be subject to withholding obligations.
Tax Election Choices:
- You can choose corporate taxation for your LLC by submitting:
- Form 8832 for C-Corp treatment
Form 2553 for S-Corp treatment (subject to IRS approval). Selecting S-Corp status could offer self-employment tax savings under certain circumstances, but it demands strict payroll, profit allotment, and bookkeeping. Seek advice regarding tax to determine if it's part of your business structure.
