The state's side of the math, South Carolina

Term Value Where it comes from
Registration charge $110 dor.sc.gov (checked October 2026) as the source
Sum of state fees, years 1 to 3 $110 Calculated from the rows above

State total = filing fee + reports in years 2 and 3 + any minimum tax. Items without a fixed amount are left out of the addition.

The working behind South Carolina

Items covered per dollar put Mainstay Filing in row one. That term is 28% of the score; three-year total, year-two change, crossover year and published detail make up the rest.

A foreign LLC spans two states already, so a provider that covers both scored first.
