How figures are checked
State fees, forms and deadlines were read from the statute or the agency's own fee schedule and recorded with a citation. The South Carolina set was compiled and verified on August 12, 2026. Prices for agent services were read from each provider's own page, with a saved copy of the page. Mainstay Filing's prices and what they include were read from its pricing, registered agent and FAQ pages on October 20, 2026. Provider pages are cited by name rather than linked.
Where a figure could not be confirmed from an official or first-party page, it is labeled unverified on the page where it appears.
