How to Start a South Carolina Corporation — Step by Step

Your corporation's name has to be distinguishable from every other business name already on file with the South Carolina Secretary of State. "Distinguishable" is a legal test, not just a gut check — a name that differs only by punctuation, spacing, or a filler word like "the" may still collide with an existing entity and get your Articles rejected.

Start with the state's business name search. Search your intended name and a few near-variations. If something close already exists, adjust before you file rather than after.

Name rules for South Carolina corporations

• The name must contain a corporate designator: "Corporation," "Incorporated," "Company," or "Limited," or an abbreviation such as "Corp.," "Inc.," "Co.," or "Ltd."
• It must be distinguishable from all active names on the Secretary of State's register.
• Words implying a regulated activity — "bank," "trust," "insurance," "engineering" — may require approval from the relevant state agency before the name can be used.
• It cannot falsely imply a government affiliation.

Reserving a name

If you have settled on a name but are not ready to file, South Carolina lets you reserve it with the Secretary of State for a limited period. A reservation holds the name while you line up your registered agent, capitalization, and other details. It does not create the corporation — it only parks the name.

Before you file, you need a registered agent lined up and willing to serve, because South Carolina asks for the agent's signed acceptance with your Articles of Incorporation.

The registered agent is the corporation's official recipient for legal process and state correspondence. State law requires every corporation to keep an agent with a physical South Carolina street address — a registered office — staffed during normal business hours.

Who can serve

• You — permitted if you have a South Carolina street address and accept that the address becomes part of the public record.
• A director, officer, or trusted individual — anyone with a real South Carolina street address who agrees to the role.
• A commercial registered agent service — a company authorized to act as agent in South Carolina, which keeps its own professional address on the public register and forwards documents to you.

Why the choice is not trivial

Whatever address you list becomes searchable in the public business record. Owners who work from home, travel often, or live out of state usually prefer a commercial service so their personal address stays private and so there is always someone available to accept a summons — missing service of process because no one was home can lead to a default judgment.

The Articles of Incorporation are what legally create your corporation. File them online through the South Carolina Business Filings portal for the fastest turnaround, or by mail if you prefer paper.

Online filings generally clear in about one to two business days; mailed filings can take up to two weeks. The receipt card on this page shows the current state fee.

What the Articles must include

• Corporate name — with its required designator, matching what you cleared in Step 1.
• Registered agent and registered office — the agent's name and physical South Carolina address, plus the agent's signed acceptance.
• Authorized shares — the total number of shares the corporation may issue. If you plan more than one class of stock, you describe the classes and their rights here. Many small corporations authorize a round number of common shares and issue only a portion at the start.
• Principal office address — the corporation's main business address.
• Incorporators — the name and address of each person forming the corporation.

A note on authorized shares

Authorizing shares is not the same as issuing them. You might authorize a large block but issue only what the founders actually take. Authorizing extra shares up front leaves room to bring on investors or grant equity later without amending the Articles. This is worth a short conversation with your accountant or attorney before you file.

Bylaws are the corporation's internal operating manual. South Carolina does not require you to file them with the state, and they never become public — but a corporation without bylaws is a corporation without agreed rules for how it governs itself.

Soon after the Articles are accepted, the incorporators or the initial board hold an organizational meeting. At that meeting the corporation typically:

• Adopts the bylaws
• Elects the initial board of directors (if the incorporators seated the board)
• Appoints officers — at minimum a president and a secretary, often a treasurer as well
• Authorizes the issuance of stock to the founding shareholders
• Approves opening a corporate bank account
• Sets the fiscal year and adopts a corporate seal and stock ledger if desired

Why the paperwork matters

The written minutes of this meeting, the adopted bylaws, and the stock ledger are your first corporate records. Courts look at whether a corporation actually observed its formalities when deciding whether to respect the liability shield. Skipping the organizational meeting is one of the most common ways new owners quietly undermine the protection they paid to set up.

An Employer Identification Number is the corporation's federal tax ID — a nine-digit number issued free by the IRS. Every corporation needs one; it is not optional the way it can be for a single-member LLC.

You need the EIN to

• File federal corporate tax returns
• Open a business bank account (banks require it)
• Hire and pay employees
• Elect S corporation status, if you go that route

How to apply

Apply online through the IRS EIN Assistant at IRS.gov. The application takes about ten minutes and issues the number immediately — you can print the confirmation and use it the same day. The online application needs a responsible party with a U.S. Social Security number or ITIN. Founders without one apply by fax or mail using Form SS-4.

This is the step that trips up people who assume "filing with the Secretary of State" is the whole job. For a corporation, the ongoing state relationship is with the Department of Revenue, not the Secretary of State.

The initial report (CL-1)

When your corporation begins doing business in South Carolina, it files an initial report — the CL-1 — with the Department of Revenue. This registers the corporation on the tax side and establishes the corporate license fee obligation.

Ongoing corporate returns

Each year, the corporation files a corporate income tax return — the SC1120 for a C corporation, or the SC1120S if you have elected S corporation status — and pays the corporate license fee that is calculated on that return. There is no separate Secretary of State annual report; the Department of Revenue filing is the recurring state obligation. If the corporation sells taxable goods or services, it also registers for and remits sales tax through the Department of Revenue.

Separating corporate and personal money is the practical heart of maintaining your liability protection. Pay corporate expenses from corporate accounts, deposit corporate income into corporate accounts, and never treat the business checking account as an extension of your wallet.

What banks usually ask for

• The stamped Articles of Incorporation from the Secretary of State
• The IRS EIN confirmation letter
• The adopted bylaws and a corporate resolution naming who may sign
• Government-issued ID for the authorized signers

Keeping the corporation compliant

• Department of Revenue: file the annual SC1120 or SC1120S and pay the corporate license fee on time.
• Registered agent: if your agent changes address or resigns, update the record with the Secretary of State promptly — a stale agent address leaves the corporation technically out of compliance.
• Corporate records: hold and document annual shareholder and director meetings, keep the stock ledger current, and record major decisions in minutes.
• Licenses: South Carolina has no single statewide business license, but many professions and localities require their own permits on separate cycles.
