Registered Agent in South Carolina: requirements, cost & best options

South Carolina publishes your agent's name and street address in its searchable business registry, where data brokers and process servers find it. The statute demands a street address for the agent — a PO box alone won't satisfy § 33-44-108 — so home-based founders end up exposing their residence unless they appoint a commercial agent, whose SC address takes the public slot instead.

Out-of-state & non-resident founders: Out-of-state and international founders can own a South Carolina LLC without restriction, but an individual agent must reside in South Carolina — so non-residents effectively need a commercial agent or an SC-resident individual. Two tax notes for non-residents: SC withholds 5% on a nonresident member's SC-source income (waivable via the I-309 affidavit), and the zero-upkeep advantage only holds if you keep default taxation.

The first thing to understand about a South Carolina LLC is that its ongoing obligations depend on its federal tax classification, not on any Secretary of State schedule. A default-taxed LLC — partnership or disregarded entity — has no annual report and no recurring SoS fee; the Uniform LLC Act South Carolina still uses (Title 33, Chapter 44) simply never created one. Form the LLC for $110 and, on the state-filing side, you're done.

The election is the trap. An LLC that elects corporate taxation (C or S) must file the CL-1 Initial Annual Report of Corporations with the Department of Revenue within 60 days of commencing business, paying the $25 minimum license fee — and from then on files annual SC1120 or SC1120S returns with the recurring license fee ($15 + $1 per $1,000 of capital). The S-corp election that saves self-employment tax quietly converts your zero-paperwork LLC into an annual DOR filer. Budget for that before electing.

Terminology is its own small quirk: the statute never says 'registered agent' — it says 'designated office' and 'agent for service of process' (§ 33-44-108), though the Secretary of State's own forms use 'registered agent,' so both are correct in practice. The agent must be an SC-resident individual or an authorized entity at a South Carolina street address ('another' LLC may serve — not the LLC itself). Changing agents is a $10 Notice of Change (Form F0080), filed in duplicate with the new agent's signed consent. No publication requirement. And on taxes: under H.4216 (2026), pass-through profits are taxed at 1.99% under $30,000 and 5.21% above — a rewrite most older guides haven't caught. Non-resident members face a 5% withholding on SC-source income unless they file the I-309 affidavit.
