How to Start a Business in South Carolina (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

To start a business in South Carolina you choose a structure, file with the Secretary of State - Articles of Organization for an LLC cost $110 - obtain a free federal EIN, and register with the South Carolina Department of Revenue. If you sell tangible goods you also need a retail license, which costs $50. Local licenses are handled by your city or county.

Quick Answer

Articles of Organization: $110 - South Carolina Secretary of State
Retail license: $50 - SCDOR, required if you sell tangible goods
Federal EIN: $0 - free from the IRS
State business license: None statewide; cities and counties license locally
Registered agent: Required, with a South Carolina address
S corporation: Federal Form 2553, then SC1120S with the SCDOR

Step 1: Choose a Business Structure

The structure decision drives everything that follows: what you file, what you pay, and whether your personal assets are exposed. The realistic options are a sole proprietorship, a general partnership, a limited liability company, or a corporation. Most new South Carolina small businesses choose an LLC, because it gives a liability shield with far less formality than a corporation.

A sole proprietorship requires no state filing at all, which is why people default into it - but it offers no separation between business and personal liability. A corporation offers the shield plus a familiar structure for outside investors, at the cost of bylaws, directors, and minutes. Read what an LLC is and S-corp vs LLC before filing, because changing later costs more than deciding now.

Whatever you choose, check the name first. Run a South Carolina business entity search against the Secretary of State's records; a name must be distinguishable from existing entities. Availability on the state register is not the same as trademark clearance - see trademarking a business name in South Carolina and the national trademark guide.

Step 2: Appoint a Registered Agent

South Carolina requires every registered entity to name a registered agent with a South Carolina address who can accept service of process during business hours. The agent's name and address go on the formation document and appear on the public record.

You can act as your own agent if you have a South Carolina street address and are reliably available during business hours; a post office box will not do. Many owners use a commercial agent to keep a home address off the public record and to guarantee that a lawsuit notice is never missed while they are on site with a client. See South Carolina registered agent requirements and the national registered agent guide.

Step 3: File With the Secretary of State

An LLC is created by filing Articles of Organization with the South Carolina Secretary of State. The filing fee is $110. Corporations file Articles of Incorporation instead. Filings are submitted through the Secretary of State's Business Entities Online system, which is faster than paper and gives you an immediate record.

The document itself is short: the entity name including a required designator, the registered agent and office, the organiser, and whether the LLC is member-managed or manager-managed. For the field-level detail see South Carolina Articles of Organization and South Carolina LLC cost. A company already formed in another state registers instead as a foreign LLC in South Carolina.

Filing is also the moment to write the internal rulebook, even though the state never sees it. An operating agreement sets out ownership percentages, how profits are split, who can bind the company, and what happens when a member leaves. Single-member LLCs benefit too: it is documentary evidence that the LLC is a real, separate business.

Step 4: Get a Free EIN

The Employer Identification Number is the federal tax ID that banks, payroll providers, and the SCDOR expect. It is free from the IRS on Form SS-4, and the online application issues the number immediately during posted hours. Apply after the entity is approved so the EIN is issued in the exact legal name on the state record.

Any multi-member LLC, any business with employees, and any entity electing corporate taxation needs one. A single-member LLC with no employees can technically use the owner's Social Security number but should not - the EIN costs nothing and keeps an SSN off vendor paperwork. See how to get an EIN and getting an EIN in South Carolina.

Step 5: Register With the Department of Revenue

The South Carolina Department of Revenue handles state tax registration through its Business Tax Application. If you sell tangible personal property at retail you must obtain a retail license; the licensing fee is $50. The retail license authorises you to collect and remit South Carolina sales tax, and you must hold it before your first taxable sale.

If you hire employees, you also register for income tax withholding with the SCDOR and for unemployment insurance with the Department of Employment and Workforce. Entities taxed as corporations or S corporations file their own returns - an S corporation files Form SC1120S. For ongoing obligations see South Carolina LLC tax filing, South Carolina annual report requirements, and the national business tax guide.

Step 6: Handle Local Licensing

South Carolina does not issue a single general statewide business license. General business licensing is municipal: cities and many counties require a local business license, usually priced by gross receipts and class of business, renewed annually. A business operating in several municipalities may need a licence in each.

Layered on top are activity-specific permits - food service, alcohol, childcare, contracting - and profession-specific licences issued by state boards to individuals rather than companies. Confirm zoning before signing a lease or starting a home-based operation. Work through South Carolina business licensing and the national business license overview, and check unfamiliar terms in the glossary.

Step 7: Decide How the Business Is Taxed

By default, a single-member LLC is disregarded and a multi-member LLC is taxed as a partnership, with profit flowing to the owners' personal returns and subject to federal self-employment tax at 15.3%. That default is fine for most small businesses and requires no election.

Once profit is consistently well above what you would pay yourself as a salary, the S-corporation election becomes worth modelling. It lets you take part of the profit as a distribution outside self-employment tax after paying a reasonable salary, at the cost of payroll administration and an extra return. The election is federal, made on Form 2553; South Carolina then taxes the entity as an S corporation on Form SC1120S. See the S-corp election in South Carolina. Also consider a single-member LLC structure, and plan the exit - how to dissolve an LLC in South Carolina - before you need it.

Two practical notes on sequencing. First, do not file Form 2553 before the entity exists and has an EIN, because the form asks for both the legal name and the employer identification number exactly as the IRS holds them. Second, an S election changes how you must pay yourself: salary runs through payroll with withholding and quarterly employment tax returns, so budget for a payroll provider before you elect rather than after. If the numbers do not clearly justify that overhead, the default pass-through treatment is the right answer and you can revisit the election in a later tax year.

Finally, put the recurring dates on a calendar the week you open: the SCDOR filing frequency you are assigned, your local licence renewal, your federal estimated payment dates, and any Secretary of State filing your entity type requires. Most compliance failures in South Carolina are missed dates rather than misunderstood rules.
