Commercial RA cost

~$125/yr

Self-serving as RA places your home address on the public SC SOS record. Commercial RA services ($50–$150/yr) keep your address private and ensure legal mail is never missed — especially important for out-of-state owners and real estate holding LLCs.

1. Search for name availability through the SC SOS Use the South Carolina SOS entity name search at businessfilings.sc.gov to confirm your desired LLC name is available and not deceptively similar to an existing SC entity. The name must include an LLC designator (LLC, L.L.C., Limited Liability Company, Limited Liability Co., or LC) under SC Code § 33-44-105. Optional: reserve the name for 120 days ($25) while preparing documents.
2. Appoint a South Carolina registered agent Designate a registered agent with a physical South Carolina street address (no PO boxes) who is available during normal business hours. SC residents with an SC address may self-serve as RA, but self-serving places your home address on the public SOS record. Commercial RA services ($50–$150/yr) preserve privacy and ensure legal mail is never missed.
3. File Articles of Organization with the SC Secretary of State File online through businessfilings.sc.gov ($110 fee). You need to provide: LLC name, registered agent name and SC street address, and organizer name and signature. Member names are not required on the Articles. Standard online processing is typically 2–5 business days.
4. Draft an Operating Agreement Although not required to be filed with the state, an Operating Agreement governs membership percentages, voting rights, profit and loss allocation, member admission and exit procedures, and dissolution under SC Code § 33-44-103. For multi-member LLCs — especially real estate, manufacturing, and port-trade entities — the Operating Agreement is the primary governance document.
5. Obtain an EIN from the IRS After the Articles of Organization are approved, apply for an EIN at irs.gov/ein. The online application takes under 15 minutes and issues the EIN immediately. Print the EIN Confirmation Letter (CP 575) for bank account opening.
6. Register with the SC Department of Revenue if selling taxable goods or services If your LLC will sell tangible personal property or taxable services in South Carolina, register for a SC Retail License at dor.sc.gov ($50 one-time fee) before the first taxable sale. South Carolina's state sales tax rate is 6%; many counties add a 1%–3% local option sales tax. Construction and real estate LLCs should also verify whether professional licenses are required through the SC Contractor's Licensing Board.
7. Open a business bank account Bring your EIN Confirmation Letter, Articles of Organization approval, photo ID, and Operating Agreement. South Carolina's banking market includes South State Bank (regional), First Reliance Bank, and all major national banks. A separate business bank account is the most important step to maintaining the LLC's liability protection.
8. Maintain your registered agent — no annual report due Unlike most states, South Carolina does not require LLCs to file an annual report. The primary ongoing compliance obligation is maintaining a valid registered agent with a physical SC street address. If the RA changes, update the SOS record promptly. The absence of an annual report eliminates the most common source of inadvertent administrative dissolution. Calendar: SC LLC owners only need to track their registered agent renewal and any SCDOR tax filing deadlines.

Formation context

Who should form in South Carolina?

Recommended for

South Carolina residents forming a business operating primarily in SC; Southeastern entrepreneurs who want no annual report obligation — $110 formation, $0/yr ongoing SOS fees; Real estate investors and holding LLC structures for Charleston-area and Lowcountry property; Port-of-Charleston logistics, manufacturing, and supply-chain LLCs leveraging SC's automotive manufacturing corridor (Boeing, Volvo, Mercedes-Benz Vans)

Tax treatment (default)

Pass-through by default: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). South Carolina imposes no franchise tax on LLCs. Members pay SC's graduated individual income tax (0%–6.4% for 2026, stepping down to 6% by 2027) on SC-source pass-through income. Corporate entities (those electing C-corp treatment) pay SC's 5% flat corporate income tax.

If you live outside South Carolina but form here, you will likely need to register as a foreign LLC in your home state for active business operations — usually eliminating the cost advantage. SC is primarily appropriate for founders with genuine SC-nexus business activity.

No publication requirement in South Carolina — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common South Carolina LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your South Carolina deadline, fee, and the consequences of missing it.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
