Start a South Carolina LLC: Step-by-Step

Your LLC's name has to be distinguishable from every other business name already registered with the South Carolina Secretary of State. "Distinguishable" is a legal test, not a gut-feel one. Two names that differ only in punctuation, spacing, or filler words like "the" and "and" may be treated as the same name and rejected.

Start with the state's business name search at the Secretary of State's business filings site. Search your first choice and a couple of near-variants. If something too similar already exists, pick a different name before you file: a rejected filing costs you days.

The naming rules

• Under S.C. Code § 33-44-105, the name must contain "limited liability company" or "limited company," or an abbreviation: "L.L.C.," "LLC," "L.C.," or "LC." "Limited" may be shortened to "Ltd." and "company" to "Co."
• It cannot imply the company is a bank, insurance company, or other regulated entity without the appropriate approvals.
• It cannot falsely suggest a government affiliation.
• It must be distinguishable from the corporations, limited partnerships and companies already on file, and from reserved or registered names.

Reserving a name

If you're not ready to file the Articles yet but want to lock the name, South Carolina lets you reserve an available name with the Secretary of State for $25. The reservation gives you exclusive use for a nonrenewable 120-day period, and it can be transferred to someone else for $10. A reservation holds the name; it does not create the LLC. Most people skip this and simply file the Articles once they've confirmed the name is free.

Operating under a different name

South Carolina has no statewide DBA or fictitious-name registry. If you plan to trade under a name different from your LLC's legal name, any registration happens at the county level, if at all: the practice is informal compared to states with a formal state DBA filing. Confirm with the county clerk of court where you operate.

Before you file, you need a registered agent lined up. The agent is named in the Articles of Organization, signs the form, and gives a South Carolina street address. The Secretary of State's forms say registered agent; the LLC Act (§ 33-44-108) calls the role an agent for service of process and pairs it with a designated office in the state, which need not be a place of business.

South Carolina law requires every LLC to keep an agent for the life of the entity. The agent receives service of process (lawsuits and legal summonses) plus official state correspondence on behalf of the company. If there's no valid agent on file, the LLC is out of compliance and risks missing a legal action entirely.

Who can be your agent

• You, if you're a South Carolina resident. Your address becomes part of the public record.
• A trusted individual who lives in South Carolina, such as a co-owner, an employee, or an attorney.
• A company: a domestic corporation, another LLC, or a foreign corporation or company authorized to do business in South Carolina. That's how a commercial registered agent service serves, putting a professional address on the public file instead of yours. Note the word "another": your LLC can't be its own agent.

Why people pay for this

The registered agent address is public and searchable. Owners who work from home, travel, or simply value privacy often use a commercial service so their home address never lands in a state database. A service also removes the risk of missing a hand-delivered lawsuit because you happened to be out.

The Articles of Organization is the filing that brings your LLC into legal existence. You file it with the South Carolina Secretary of State, either online at businessfilings.sc.gov or by mailing a paper form. The form is F0006, and the state filing fee set by S.C. Code § 33-44-1204 is $110. Online is the faster and cleaner path, and the system lets you save the filing and fix errors until it's accepted. On paper, you mail two completed copies with a $110 check and a self-addressed stamped envelope to the Secretary of State's office at 1205 Pendleton Street, Suite 525, Columbia, SC 29201.

The Secretary of State doesn't publish a processing time, and its pages list no expedite fee; it says only that online filing is faster than paper. Once the state processes the Articles, the LLC is officially on record and you'll receive the filed document.

What the Articles ask for

• LLC name: your full legal name with the required designator
• Designated office address: a South Carolina address the state keeps on file for the company
• Registered agent: name and South Carolina street address, plus the agent's signature
• Organizers: the name and address of each organizer (one is enough), each of whom signs
• Management structure: check the box only if the LLC will be manager-managed, and list the managers
• Optional items: a set term, member liability for company debts, a delayed effective date, or other provisions

What you don't have to disclose

You don't have to list every member, spell out ownership percentages, describe your finances, or write a detailed business purpose. The Articles are a lean formation document. The internal details of who owns what and how decisions get made live in your operating agreement, which stays private.

An operating agreement is the LLC's internal rulebook. South Carolina does not require you to file it, and it never goes into any public database, but you should have one in place before you take on partners, open accounts, or start doing real business.

What a solid operating agreement covers

• Ownership: who the members are and each one's percentage interest
• Capital contributions: what each member put in at the start and any future obligations
• Profit and loss allocation: how gains and losses are split, which does not have to track ownership exactly
• Distributions: when and how money is paid out to members
• Management: whether members run the company or designated managers do, and which decisions require a member vote
• Voting: how votes are weighted and what majority is needed for various actions
• Transfers: what happens when a member wants to sell or leave, including any rights of first refusal
• Dissolution: how the company winds down and distributes its remaining assets

For a single-member LLC, the agreement helps prove the company is a genuine separate entity, which matters when a court evaluates your liability protection. Banks frequently ask for it. For a multi-member LLC it's essential. Without one, South Carolina's statutory defaults control everything, and those defaults rarely match what the members actually had in mind.

An Employer Identification Number is a nine-digit federal tax ID, free from the IRS. It functions as the business's version of a Social Security number and shows up on tax filings, bank applications, and payroll paperwork.

When you need one

• Your LLC has more than one member (multi-member LLCs file a partnership return and must have an EIN)
• You plan to hire employees
• You want a business bank account (nearly every bank requires it)
• You've elected S corporation or C corporation tax treatment

A single-member LLC with no employees can technically use the owner's Social Security number for federal taxes, but almost every advisor recommends getting an EIN anyway. It keeps your SSN off business paperwork and makes opening an account far smoother.

How to apply

The fastest route is the IRS EIN Assistant on IRS.gov, which you complete online. It takes about ten minutes and the number is issued immediately, so you can print the confirmation and use it that day. You need a U.S. Social Security number or ITIN to apply online; applicants without one file Form SS-4 by fax or mail.

Keeping business and personal money separate isn't optional if you want the liability shield to hold. Paying personal bills from the company account, or funneling business income into your personal account, gives a court a reason to disregard the LLC and reach your assets.

What banks usually want

• Filed Articles of Organization from the Secretary of State
• Your IRS EIN confirmation
• The operating agreement (many banks ask for it; bring it either way)
• Government-issued ID for everyone who will sign on the account

South Carolina community banks and credit unions are often more flexible with brand-new LLCs than the big national chains, and several online business banks can open an account without a branch visit. Weigh each account's monthly fees, transaction caps, and minimum-balance rules against the others before you settle on one.

Here's the good news South Carolina owners appreciate: there is very little recurring state maintenance for a standard LLC.

No Secretary of State annual report

A default LLC does not file an annual report with the Secretary of State and pays no annual state renewal fee; the Department of Revenue says an LLC not taxed as a corporation is not subject to the annual report or the license fee. This is the single biggest difference from most other states, where a missed annual report is the leading cause of losing good standing. South Carolina LLC owners simply don't face that yearly deadline.

The corporate-tax exception

If your LLC elects to be taxed as a corporation, it files with the South Carolina Department of Revenue instead. It submits the CL-1, Initial Annual Report of Corporations, within 60 days of commencing business, with a $25 minimum license fee. Going forward, it files SC1120 or SC1120S, and the annual report on that return is due by the 15th day of the fourth month after the tax year ends, with a license fee of at least $25. This only applies if you've made the corporate election.

Registered agent upkeep

Keep a valid registered agent with a current South Carolina street address on file at all times. If the agent moves, resigns, or you switch, file a statement of change with the Secretary of State promptly; it costs $10.

Taxes and local licenses

Federal filing depends on your tax treatment: Schedule C for a single-member LLC, Form 1065 for a partnership, or the corporate forms if you elected. South Carolina taxes pass-through income at the member level. Most cities and counties require a local business license, often based on gross receipts, and sellers of taxable goods register for a retail license with the Department of Revenue. These run on their own schedules, separate from your LLC formation.
