How to File an LLC in South Carolina

By Thomas Garrett · Practical Affairs Writer

What you need to do to form an LLC in South Carolina

To form an LLC in South Carolina, you file Articles of Organization with the South Carolina Secretary of State. The process takes about two weeks if you mail the documents, or same-day if you file online. You will need to choose a business name that is not already registered, pay a filing fee, and designate a registered agent — someone in South Carolina who can receive legal papers on behalf of your business.

The Secretary of State does not require you to have a business plan, a federal tax ID, or a physical office before you file. You can form an LLC as a single owner or with partners. Once your Articles are approved, your LLC legally exists and you can open a bank account and begin operations.

Key Takeaways

  • You file Articles of Organization with the South Carolina Secretary of State, either online for same-day processing or by mail for about two weeks.
  • Your LLC name must not match or closely resemble any name already registered in South Carolina, and you can check availability free on the Secretary of State website.
  • You must designate a registered agent — a person or business located in South Carolina who receives legal documents on your behalf.
  • The filing fee is $110 if you file online or $125 if you mail the documents; this is a one-time cost to form the LLC.
  • After approval, you should obtain an Employer Identification Number (EIN) from the IRS, even if you are a single-owner LLC, to keep your personal and business finances separate.

Check your business name and reserve it if needed

Before you file, search the South Carolina Secretary of State's business name database to make sure your chosen name is available. Go to scbiz.sc.gov, click "Business Search," and type in the name you want. If it is taken, you will need to choose a different name. The search is free and takes a few minutes.

Your LLC name must include "LLC," "L.L.C.," or "Limited Liability Company" at the end. You cannot use words that suggest you are a bank, insurance company, or other regulated entity unless you have a license. If you find your name is available but you are worried someone else might register it before you file, you can reserve it for 120 days by paying a $25 reservation fee to the Secretary of State.

Designate a registered agent in South Carolina

Every LLC in South Carolina must have a registered agent — a person or business that receives legal documents, tax notices, and lawsuits on behalf of your LLC. The agent must have a physical street address in South Carolina (a PO box does not count). This can be you, a co-owner, an employee, or a professional registered agent service.

If you use a professional service, they typically charge $50 to $150 per year. If you name yourself or a co-owner, make sure that person is willing to receive mail at their South Carolina address and will forward important documents to you promptly. The registered agent's name and address go on your Articles of Organization, and you can change the agent later by filing a form with the Secretary of State.

Complete and file your Articles of Organization

The Articles of Organization is a one-page form. You can file it online through the Secretary of State's website or print it and mail it. The form asks for your LLC name, the registered agent's name and address, the principal office address (where you will run the business), and the name and address of each member (owner). If you have more than one member, list them all.

You do not need to describe what your business does or provide financial information. You do not need to attach bylaws or an operating agreement (though you should create an operating agreement for your own records, especially if you have partners). Sign the form, include the filing fee, and submit it. Online filing costs $110 and is processed the same day. Mailed filings cost $125 and take about two weeks.

Obtain an Employer Identification Number from the IRS

After your LLC is approved, you should get an Employer Identification Number (EIN) from the IRS. This is a nine-digit number that identifies your business for tax purposes. Even if you are a single owner with no employees, an EIN keeps your personal and business finances separate and makes it easier to open a business bank account.

You can apply for an EIN free of charge on the IRS website at irs.gov, or by phone at 1-800-829-4933. Online applications are processed immediately and you receive your number the same day. You will need your Social Security number, your LLC's name, and the date you formed it. The IRS will send you a confirmation letter by mail within two weeks.

Open a business bank account and set up your records

Once you have your EIN, contact a bank and open a business checking account in your LLC's name. Bring your Articles of Organization approval letter, your EIN confirmation, and a photo ID. A business account keeps your personal money separate from business money, which protects your personal assets if your LLC is sued.

You should also create an operating agreement — a document that describes how your LLC will be run, how profits are split, and what happens if an owner wants to leave. This is not filed with the state, but it is important for your own records and protects you if there is a dispute between owners. If you are a single owner, an operating agreement is optional but still recommended.

Understand ongoing requirements and annual filings

After you form your LLC, South Carolina requires you to file an Annual Report every year. The report is due by the last day of the month in which your LLC was formed. The fee is $25 if you file online or $50 if you mail it. The report confirms that your LLC still exists and that your registered agent information is current.

You must also pay South Carolina income tax on your LLC's profits, and you may owe federal self-employment tax if you are a single owner. Consult a tax professional or accountant to understand your tax obligations. If you do not file your Annual Report on time, the Secretary of State will send you a notice, and your LLC can be dissolved if you do not file within a certain period.

Frequently Asked Questions

Can I form an LLC with just one owner?

Yes. A single-owner LLC is called a sole proprietorship for tax purposes, but it still gives you liability protection. You still need a registered agent, file Articles of Organization, and pay the filing fee. The process is the same as forming an LLC with multiple owners.

What happens if my chosen business name is already taken?

You must choose a different name. The Secretary of State will reject your filing if the name is identical or confusingly similar to one already registered. You can check availability free on scbiz.sc.gov before you file, or you can reserve a name for 120 days by paying a $25 fee.

Do I need a lawyer to file an LLC in South Carolina?

No. The Articles of Organization form is straightforward and you can file it yourself online. However, a lawyer can help you draft an operating agreement, understand tax implications, or handle more complex ownership structures. Many people file on their own and consult a lawyer only if questions arise.

How long does it take to form an LLC after I file?

If you file online, your LLC is typically approved the same day. If you mail your documents, approval takes about two weeks. You can begin operations as soon as you receive your approval letter from the Secretary of State.

What is the difference between an LLC and a corporation in South Carolina?

Both offer liability protection, but an LLC is simpler to run and has fewer reporting requirements. A corporation requires a board of directors, bylaws, and more formal meetings. An LLC is usually cheaper to form and maintain, which is why most small businesses choose it.
