Government side of the board, South Carolina
Our state figure counts three items: the filing, two years of reports and a minimum tax where one exists. Variable costs like publication are excluded.
How the ranking came out
Filings handled per dollar put Mainstay Filing first. That term is 30% of the ranking; measured three-year cost, renewal drift, break-even year and price clarity make up the rest.
One agent price in every state outscored SC Registered Agent.org's lower one-state quote.
