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 — especially important for manufacturing and Port-district LLCs where the public record is searchable by supply chain partners.

1. Search for name availability through the SC SOS Use the South Carolina SOS entity 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). SC residents with a SC address may self-serve, 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 — especially important for North Charleston manufacturing and Port-area LLCs receiving supply chain legal notices.
3. File Articles of Organization with the SC Secretary of State File online at businessfilings.sc.gov ($110 fee). Provide: LLC name, registered agent name and SC street address, and organizer name and signature. Member names are not required on the Articles of Organization. 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, and dissolution under SC Code § 33-44-103. For Charleston-area manufacturing LLCs in the Boeing/Volvo/Mercedes supply chain, a clear Operating Agreement defining member authority and capital contributions is critical for negotiating supply contracts and bank financing.
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 for local Charleston and county business licenses If your LLC operates within the City of Charleston or Charleston County limits, you must obtain a city/county business license. License fees are based on gross revenue. Contact the Charleston City Revenue Collection at charleston-sc.gov. North Charleston businesses contact the City of North Charleston at northcharleston.org. Port-area and industrial-park LLCs in Berkeley and Dorchester counties should verify county license requirements with their respective county offices.
7. 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%; Charleston County adds a 1% local option sales tax for a combined 7% rate. Manufacturing LLCs with B2B sales to Boeing or Volvo should confirm sales tax nexus treatment with an SC CPA — manufacturing exemptions may apply for equipment and raw materials.
8. Open a business bank account and maintain your registered agent — no annual report due Open a business bank account in Charleston (TD Bank, Wells Fargo, South State Bank, First Reliance Bank, and First National Bank all have strong Charleston presence). Bring your EIN Confirmation Letter, Articles of Organization, photo ID, and Operating Agreement. Ongoing compliance: maintain a valid SC registered agent. South Carolina requires no annual report — no recurring SOS filing to track. Set calendar reminders only for SCDOR tax obligations and city/county business license renewals.

South Carolina Uniform Limited Liability Company Act, SC Code of Laws §§ 33-44-101 et seq.; South Carolina Revenue Procedures Act, SC Code § 12-54-1 et seq.; City of Charleston Business License Ordinance; IRS Rev. Rul. 77-137 on single-member LLC tax treatment.

Formation context

Who should form in South Carolina?

Recommended for

Charleston-area manufacturing, logistics, and supply-chain LLCs in the Boeing/Volvo/Mercedes-Benz Vans I-26 corridor; Port of Charleston freight forwarding, customs brokerage, and 3PL LLCs leveraging SC's container port infrastructure; Real estate investors and short-term rental operators in Charleston's historic downtown and Lowcountry coastal market; South Carolina residents who want the lowest ongoing compliance cost in the Southeast — $110 formation, $0/yr SOS obligation

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 toward 6% by 2027) on SC-source pass-through income. City of Charleston and Charleston County business licenses are based on gross revenue, not on LLC net income or pass-through.

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. Form in the state where you genuinely operate. SC's no-annual-report advantage is most valuable for businesses with real SC-nexus activity, not for purely remote formation-state shopping.

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 (Charleston) 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.
