Do You Pay Taxes When You Purchase a Car From a Private Party in South Carolina?

When buying a vehicle in South Carolina, you’ll pay 5% of the vehicle’s purchase price or $500 (whichever is lower), whether you buy from a private seller or a car dealer.
How Much are Used Car Sales Taxes in South Carolina?
South Carolina's tax law does not discriminate between private-party and dealership sales. Unless you qualify for a tax exemption (discussed below), you are required to pay tax on your vehicle purchase.

What is the Infrastructure Maintenance Fee?

According to the South Carolina Department of Motor Vehicles, residents of South Carolina pay what's known as an Infrastructure Maintenance Fee (IMF) when they purchase a car and register it in the state.

IMF is 5% of the purchase price but can’t exceed $500. So, if your vehicle costs $9,999 or less, you'll pay 5% of its price in the IMF. If it costs $10,000 or more, your IMF will be a flat $500.

The IMF replaced vehicle sales tax on July 1, 2017, as part of a piece of legislation known as the Roads Bill. Prior to the IMF, residents paid a straight 5% of a vehicle’s purchase price, with no cap.

The IMF’s one meaningful difference for South Carolina car buyers: it limits your tax to $500. If you’re buying a $9,000 used Toyota Corolla, the change doesn’t affect you. If you’re buying a $50,000 Cadillac Escalade, that change saves you $2,000.

South Carolina Use Tax

South Carolina’s use tax is pretty much the same as the IMF, but for out-of-state vehicles. When you purchase a car in another state and register it in South Carolina, the state levies a 5% use tax (the use tax rate is the same as the IMF, with the same cap).

If you paid sales tax on the purchase of a vehicle in another state, South Carolina gives you credit for the tax paid.

South Carolina License Plate, Title, And Registration Fees

In addition to the IMF, you owe other fees when buying a car and registering it in South Carolina, such as a vehicle title fee and registration fee.

To register your vehicle at the auditor's office, you must show proof of vehicle insurance. The first time you register a passenger vehicle, it will cost you $40 plus the $15 title transfer fee.

South Carolina's standard license plate fees are included in the registration. A vanity plate costs an additional $30.

How to Pay South Carolina Vehicle Sales Tax

Here's how to pay the IMF owed after buying a vehicle from a private seller in South Carolina:
1. To transfer ownership of the vehicle, you and the seller must complete the necessary paperwork, including the bill of sale (when you buy a used car on PrivateAuto, we provide an official South Carolina bill of sale and prompt both of you to sign it in our app at the appropriate stage of the transaction process). You'll need the following documents to transfer car ownership in a private transaction:
2. The original car title.
3. Proof of South Carolina insurance.
4. Valid driver’s licenses or IDs
5. Calculate the amount of IMF due. Multiply the vehicle's purchase price by 5% (for purchases under $10,000).
6. Fill out the IMF form.
7. Submit payment for all taxes and fees.
8. Get payment proof from the South Carolina Department of Revenue.
9. Get your registration, title, and new license plates. Once you've paid the sales tax and turned in the necessary documentation, you'll get your new registration and title for the car. The title and registration will show that you bought the car and that the sales tax has been paid. You will get your new license plates in mail.
If you buy a used car from a private seller,it is recommended that both you and the seller go to a Department of Motor Vehicles branch to finish the transaction, which protects both of you.

Is Purchasing a Car from a Dealer Better?

A lot of people mistakenly believe that buying a car from a South Carolina dealer saves money. The opposite is true: going to a South Carolina dealer costs you more money, and it's a pain—unless spending 3 hours in a South Carolina dealership is your idea of a good time.

Dealerships charge documentation fees above and beyond all the other South Carolina taxes and fees you have to pay (the other taxes and fees are exactly the same whether you buy from a dealer or a private seller, by the way). An average documentation fee in South Carolina is $220.
Used car dealerships typically charge higher prices. Their business model is based on buying low and selling high to generate the spread that keeps them in business. To get the best deals, skip the middleman and go directly to private sellers.
We do admit that dealers bring a certain amount of convenience that you don’t traditionally get when you buy from a private seller. In fact, that’s why we exist. PrivateAuto gives you dealer-like convenience in the palm of your hand while allowing you to transact peer-to-peer with regular folks like yourself.

By shopping for used vehicles from private sellers on PrivateAuto, you avoid the doc fee and get lower prices.
