Selling a used car privately in the United States may seem like a simple process: a price is agreed upon, the contract is signed, and the vehicle is delivered. However, this transaction also involves tax obligations for both the buyer and the seller. Understand how the taxes when selling a car between individuals helps avoid penalties and ensure a completely legal sale.

Who pays taxes when selling a used car?
In most states, The buyer is the one who pays sales or use taxes when registering the vehicle with the Department of Motor Vehicles (DMV). The seller, on the other hand, is not obliged to collect or remit this tax, unless he or she acts as a regular car dealer or dealer.
Therefore, when you sell a car privately, you do not need to collect taxes. However, you must report the actual sale price on the transfer form or contract. If the buyer declares a lower amount to pay less taxes, both could face penalties in the event of a DMV audit or review.
What is the “sales tax” and how is it applied?
He sales tax or sales tax It is calculated on the total price of the vehicle. This tax varies by state and even the county or city where the car is registered.
For example:
- In Californiasales tax may exceed 10% in some areas.
- In Texasthe buyer pays a 6.25% of the sales price or fair market valuewhichever is greater.
- In Floridathe general tax is 6%plus possible local surcharges.
The DMV uses this amount to calculate taxes and fees at the time of registration. That is why it is important that the “bill of sale” (sales contract) clearly indicates the actual price and is signed by both parties.
Capital gains taxes for the seller
In most cases, The seller does not have to pay taxes on the sale of a used carsince vehicles depreciate over time. However, there is one exception: if you sell the car for more than the price you originally paid, you could be subject to capital gains taxes.
This occurs with collector, classic or exotic cars that increase in value over the years. In that case, the seller must report the gain to the Internal Revenue Service (IRS) in your annual statement, indicating the difference between the sales price and the original cost of the vehicle.
How to report the transaction correctly?
Even if you don’t have to pay taxes, you must notify the DMV of the sale and save evidence of the process. This includes:
- Complete a “bill of sale” with date, price and information of the buyer and seller.
- Sign the back of the title (pink slip) to transfer ownership.
- Deliver a notice of transfer or “release of liability” to the DMV, which releases the seller from future responsibilities.
- Keep copies of all documents in case of claims or tax verifications.
The buyer, for his part, must present these documents when registering the vehicle and pay the corresponding taxes and fees.

What happens if taxes are not paid?
If the buyer does not pay the taxes when registering the vehicle, the DMV can deny transfer of title or impose additional fines. Additionally, if the seller fails to submit the notice of sale, you could receive traffic fines or toll charges generated by the new owner.
Complying with tax and administrative obligations guarantees that the sale is valid and avoids future liabilities.
Taxes when selling a car privately in the United States may seem confusing, but the principle is simple: The buyer pays the sales tax and the seller must report the transaction correctly.
