South Carolina replaced its vehicle sales tax with an Infrastructure Maintenance Fee: 5% of the price, hard-capped at $500. Read that again — any vehicle over $10,000 pays exactly $500, whether it's a $12,000 commuter or a $90,000 truck. It's one of the lowest effective vehicle tax burdens in America, and it makes South Carolina a structurally cheap state to buy expensive vehicles in.
The trade-in still matters below the cap (tax applies to price minus trade until the $500 ceiling takes over) — but on most real purchases the fee is simply maxed, which changes your negotiating focus entirely: with tax frozen at $500, every dollar of the deal fight lives in the price, the trade allowance, the fees, and the financing. New residents bringing a vehicle into the state pay a flat $250 to title it.
Because the state's take is capped, watch the lines the dealer controls: doc fees are uncapped, typically $300–450, and the finance office knows the tax line can't scare you here. The IMF's flat structure is genuinely buyer-friendly — just don't let the savings get quietly reabsorbed elsewhere on the sheet.
Every figure above was last verified against official South Carolina sources in August 2026. Tax rules do change — the final word is always your paperwork and the DMV.
