How much are car taxes and fees in South Carolina?

The short version: no sales tax, but a capped fee instead

South Carolina doesn’t apply its regular sales tax to vehicle purchases. Instead, dealers collect a one-time Infrastructure Maintenance Fee, IMF for short, equal to 5% of the purchase price, capped at $500. That cap is the detail that matters most: once a vehicle’s price crosses $10,000, the IMF stops growing and sits at a flat $500, so a $15,000 car and a $60,000 car pay the exact same fee. Below $10,000, you’re paying the full 5% on whatever the price actually is.

Why the cap changes the math on more expensive vehicles

Because the IMF caps out at $500, it works out to a much smaller percentage of the price on a pricier vehicle. On a $10,000 car, $500 is 5%. On a $50,000 vehicle, that same flat $500 works out to 1%. This is one of the few places where buying a more expensive vehicle in South Carolina is proportionally cheaper on this one line item, worth knowing if you’re comparing an out-the-door quote against what you’d expect from a state with a standard percentage-based sales tax.

Local sales tax doesn’t stack on top

In most South Carolina purchases, county and local sales taxes add a percentage on top of the state rate. Vehicles subject to the IMF are an exception: local sales taxes do not apply on top of it. The $500 cap, or the 5% below that threshold, is the whole state and local sales-tax-equivalent bill on the vehicle itself. Fees for title, registration, and any dealer documentation charge are separate and still apply.

Trading in a vehicle lowers the taxable amount

If you’re trading in a vehicle as part of the deal, its value is generally subtracted from the purchase price before the 5% IMF is calculated. On a vehicle already priced above $10,000 before the trade, this usually doesn’t change anything since you’re already at the $500 cap either way. On a lower-priced vehicle, the trade-in credit can meaningfully reduce what you owe, another reason to make sure your trade-in’s value is itemized clearly on the out-the-door quote rather than folded into a single number.

The part people miss: annual county property tax

The IMF is a one-time cost at purchase. Separately, every South Carolina county bills an annual personal property tax on vehicles registered there, and it has to be paid before you can renew your registration each year. The amount depends on your county’s rate and the vehicle’s assessed value, which typically declines as the vehicle ages, so this bill isn’t fixed the way the one-time IMF is. Because rates vary by county, the same vehicle can carry a different annual bill depending on where in South Carolina it’s registered. If you’re comparing the true cost of owning a vehicle here, budget for this as a recurring line item, not a one-time closing cost.

What this means for a Greenville-area buyer

If you’re shopping in or around Greenville, the practical takeaway is simple: ask for the out-the-door price broken into its actual pieces, sale price, IMF, trade-in credit if applicable, title and registration, and any dealer fees, rather than a single bottom-line number. Then separately budget for the annual county property tax bill that shows up after the sale, since it’s easy to forget when you’re focused on the purchase price. Neither of these is a hidden or unusual charge, they’re just structured differently than in states with a standard vehicle sales tax, and it’s worth understanding the structure before you’re staring at a bill.

Next steps

If a dealer’s quote shows something labeled as “sales tax” rather than “IMF” on a South Carolina deal, ask them to clarify, it may just be a labeling habit carried over from other states, but it’s worth confirming the number matches the 5%-capped-at-$500 structure. Separately, check your county’s current property tax rate on vehicles before you buy, so the annual bill isn’t a surprise the following year.
