South Carolina Weight-Distance Tax
South Carolina has no weight-distance or highway-use tax. No state per-mile permit to buy, no separate state mileage return to file. Your load is the shared floor everyone runs on: IFTA fuel tax, IRP apportioned plates, and the federal 2290 HVUT at 55,000 lb and up. The state charges no per-mile tax on top of that.

IFTA and registration still apply
Every state, including South Carolina, still reaches you through the IFTA fuel tax (reconciled by the fuel you burn) and IRP apportioned registration (your plate). The only states that add a per-mile weight-distance or highway-use tax on top are Kentucky, New Mexico, New York, Oregon, and Connecticut.
