How Much are Used Car Sales Taxes in Kentucky?

When buying a used car in Kentucky, don’t get caught off guard by the state’s vehicle sales tax.
Kentucky's car sales tax rate is six percent of the vehicle's purchase price. Unlike many other states, Kentucky has no local sales taxes. So, 6% is the maximum you’ll pay in sales tax in Kentucky, unlike other states where local governments can tack on additional vehicle taxes over and above the state’s tax rate.

Do you Pay Taxes When you Purchase a Car From a Private Party in Kentucky?

When buying a car in Kentucky, you’ll pay 6% of the vehicle’s purchase price, whether you buy from a private seller or a car dealer. Kentucky tax law does not discriminate between the two. Unless you qualify for a tax exemption (discussed below), you are required to pay tax on your vehicle purchase.

Kentucky Sales Tax vs Usage Taxes

Sales tax is a percentage of a car's purchase price owed to the state of Kentucky when you buy a car and register it in Kentucky. The use tax ensures that vehicles purchased within the state and cars brought into the state are taxed identically.

Use taxes are pretty much the same thing, but for buying out-of-state vehicles. When you purchase a car out-of-state and register it in Kentucky, the state levies a 6% use tax (the use tax rate is the same as the Kentucky car sales tax rate).

If you paid sales tax on the purchase of a vehicle in another state, Kentucky deducts that tax so that you are not taxed twice. There are four potential scenarios.

1. You paid no sales tax in another state, in which case you owe the full 6% Kentucky sales tax. Let's say you bought a used car in Delaware and didn’t pay any sales tax, given Delaware's 0% tax rate. You’ll pay Kentucky ’s full 6% sales tax rate.
2. You paid less than 6% sales tax in another state, in which case Kentucky charges you the difference. Let’s say you bought a used car in Missouri for $23,000. Missouri car sales tax rates are 4.225%, so you paid $971.75 (.04225 X $23,000) in Kentucky tax. When you go to register your car in Kentucky, your total tax bill will be $1,380 minus the $971.75 you already paid in Missouri, for a total tax due of $408.25 to Kentucky.
3. You paid exactly 6% sales tax in Florida (the only other state with the same tax rate as Kentucky), in which case Kentucky will give you a pass.
4. You paid more than 6% in the other state (for example, Tennessee levies a 7% tax on every used vehicle purchase). We wish we could tell you Kentucky will give you a refund, but no. At least they won’t charge you any more tax.

Kentucky License Plates, Title And Registration Fees

In addition to the state sales tax, you may owe other fees when buying a car and registering it in Kentucky, such as a vehicle title fee and registration fee.

To register your vehicle at the County Clerk’s office, you must show proof of vehicle insurance. The first time you register a passenger vehicle, it will cost you $21 plus the $9 title transfer fee.

Kentucky's standard license plate fee is included in the registration fee. A vanity plate costs an additional $25.

How is Used Car Sales Tax Calculated in Kentucky ?

Sales tax is a percentage of a car's purchase price owed to the state of Kentucky when you buy a car and register it in Kentucky.

If the Department of Revenue suspects that the purchase price of the vehicle was artificially decreased, they will calculate sales tax based on the car’s fair market value.

The Department of Revenue establishes what the car is worth on the open market by referring to Kelley Blue Book, NADA value, or other reliable sources on used car prices. If they conclude that the car's fair market value is greater than its purchase price, they can opt to base sales tax on the fair market value.

It is important to note that underreporting the purchase price of a vehicle in order to avoid paying sales tax is illegal.

How to Pay Kentucky Vehicle Sales Tax

Here's how to pay the sales tax owed after buying a vehicle from a private seller in Kentucky:

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 Kentucky 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 Kentucky insurance.
4. Valid driver’s licenses or IDs
5. Calculate the amount of sales tax due. Multiply the vehicle's purchase price by 6%.
6. Fill out the sales tax form.
7. Submit payment for all taxes and fees.
8. Get payment proof from the Kentucky 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 the mail.

Is Purchasing a Car from a Dealer Better?

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

Dealerships charge documentation fees above and beyond all the other Kentucky 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 Kentucky is $450.
Used car dealerships charge higher prices on cars. 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.
