Independent comparison of registered agent services for South Carolina LLCs and corporations.
Reviewed against South Carolina Secretary of State guidance · Updated 2026-04-30
For most South Carolina LLCs, the registered agent is the only third-party compliance vendor the entity will use year after year. S.C. Code §33-44-108 sets the floor; price, privacy, and mail handling separate the providers. The rankings below reflect 2026 pricing and South Carolina-specific filing performance. Four registered agent services dominate the South Carolina market; the rankings below reflect 2026 pricing and South Carolina-specific operational performance.
In South Carolina, the registered agent’s job is heavier than the statutory floor implies. 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. The practical reason this matters when picking a provider: the entity-tax-election determines whether an annual report is required — partnerships skip it, corporations file with the Department of Revenue.
For South Carolina businesses, the three traits that separate good providers from passable ones are (1) reliable same-day handling of service of process from South Carolina state and federal courts, (2) accurate, deadline-aware reminders calibrated to South Carolina’s specific annual cycle (no annual report required for LLCs taxed as partnerships), and (3) an online dashboard that shows scanned mail within hours, not days. All four services we ranked clear the S.C. Code §33-44-108 eligibility bar; the meaningful differences are in execution. Northwest leans privacy-first, Mainstay Filing leans value-first, ZenBusiness leans formation-bundle-first, and LegalZoom leans brand-and-phone-support-first.
