Statutory requirements, filing fees, and recommended services for South Carolina businesses.
Verified against South Carolina Secretary of State · Updated 2026-04-30
Per S.C. Code §33-44-108, a South Carolina registered agent must maintain a physical street address inside South Carolina and accept service of process during ordinary business hours. The South Carolina Secretary of State records the agent’s name and address as part of the public business filing. This page documents how South Carolina treats the registered agent designation under S.C. Code §33-44-108, the fees the South Carolina Secretary of State charges to file, and the practical mistakes that trip up first-time filers.
A South Carolina registered agent is the individual or business entity that S.C. Code §33-44-108 requires every LLC and corporation to maintain as the official recipient of service of process, state tax notices, and South Carolina Secretary of State correspondence. The agent must keep a physical South Carolina street address — P.O. boxes alone do not satisfy the statute — and must be reliably available during normal business hours. The South Carolina Secretary of State, Business Filings Division files the agent’s name and street address as part of the public business record, searchable by any member of the public through the agency’s online entity database.
The registered agent designation in South Carolina is filed as part of the Articles of Organization, submitted to the South Carolina Secretary of State’s business filings division. Most filers use the South Carolina Secretary of State Business Filings online portal, which accepts the formation document, the agent designation, and the $110 filing fee in a single transaction. Online submissions typically clear in two to seven business days; paper filings can take two to four weeks depending on agency workload.
South Carolina requires no annual report for LLCs taxed as partnerships — making it effectively a no-annual-maintenance state for the majority of LLCs. LLCs taxed as corporations file an annual report with the Department of Revenue.
Once the entity is on file, the registered agent’s role continues for as long as the LLC or corporation exists. South Carolina’s ongoing maintenance is handled through an annual report at $0, due no annual report required for LLCs taxed as partnerships, and any subsequent change of registered agent is filed with the South Carolina Secretary of State via a Statement of Change at a $10 fee. The agent must file a written consent or, where the agency requires, sign the formation document itself — the South Carolina Secretary of State rejects designations that lack agent consent.
Five state-specific gotchas account for most of the registered agent problems we see in South Carolina filings.
Listing a P.O. box or commercial mailbox. S.C. Code §33-44-108 requires a physical street address, and the South Carolina Secretary of State returns filings that list anything other than a real South Carolina street. Commercial mailbox services without a registered street component (typical UPS Store-style addresses) are routinely rejected.
Using a non-South Carolina address. The agent’s address must be physically inside South Carolina. Out-of-state owners cannot list their own home address; they must either hire a commercial agent or designate a South Carolina-resident individual.
Letting the agent designation lapse without filing a Statement of Change. When a commercial agent service is terminated and a replacement is not filed with the South Carolina Secretary of State, the LLC enters a compliance gap. The $10 change fee is trivial compared with the cost of administrative dissolution and reinstatement.
Missing the annual report deadline. South Carolina’s annual report is due no annual report required for LLCs taxed as partnerships, and the registered agent is the only party who receives mailed reminders from the South Carolina Secretary of State. If the agent is unreliable, the entity can miss the deadline silently.
South Carolina’s no-annual-report-for-partnerships rule masks the LLC-taxed-as-corporation case — owners electing S-corp or C-corp status forget the SOS annual report applies in that scenario.
National registered agent services — Northwest Registered Agent, Mainstay Filing, ZenBusiness, and LegalZoom — operate in South Carolina with the same pricing and feature set they offer in every other state. For most South Carolina LLCs and corporations, a national provider is the right choice: consistent pricing, an online dashboard with scanned mail, and same-day acceptance of service of process. Northwest’s $125/year tier and Mainstay Filing’s $99/year tier are the two most common picks for South Carolina businesses that want privacy and reliability without paying premium prices.
A South Carolina-specific provider like South Carolina Registered Agent.co makes sense in narrower cases. State-focused agents tend to specialize in South Carolina filings only, which can mean faster local turnaround on Statements of Change, deeper familiarity with the South Carolina Secretary of State’s portal, and a single jurisdiction to worry about. For business owners who plan to operate exclusively in South Carolina and value a local-only operator, a state-specific provider is often a better cultural fit than a multi-state brand. The tradeoff is interface polish: state-specific services usually lack the dashboard depth and mail-forwarding automation of the national services.
