In the sale and purchase of second-hand cars, knowing the tax obligations is essential to avoid costly mistakes. Many multi-brand dealerships in Spain carry out frequent transactions with private individuals, both when buying vehicles from them and when selling vehicles to them. But when is it mandatory to apply withholding in these transactions? In this article, we clarify the situations in which this tax obligation may arise.

What is tax withholding?

Withholding is a tax mechanism whereby a company or professional making a payment withholds a percentage and pays it to the Tax Office as an advance on the tax that the recipient of the money must declare.

Withholdings apply, for example, to wages, professional services, rents or commissions. But not all transactions are subject to this mechanism.

Does withholding apply in vehicle sales and purchases?

Sale between private individuals

When a private individual sells a car to another private individual, there is no obligation to apply withholding. The buyer, however, must settle the Property Transfer Tax (ITP) with the relevant autonomous community.

Sale from dealership to private individual

When a dealership sells a car to a private individual, it must not withhold any amount from the price. The transaction will be subject to VAT or the Special Scheme for Used Goods (REBU), but not to tax withholding on payment.

Purchase of a car from a private individual by a dealership

Nor is it mandatory in this case to apply withholding. The dealership is making the purchase, and the private individual is not acting as a professional nor issuing an invoice. Therefore, there is no legal basis for withholding. The dealership only needs to keep proper proof of the transaction.

Exceptional cases: services and commissions

If the transaction includes an intermediation commission, management services or other items unrelated to the direct sale of the vehicle, it may be necessary to apply withholding. This will depend on whether the person providing the service is a professional or a company, and whether the law requires it.

Other tax obligations in sales and purchases

• ITP (Property Transfer Tax): applicable when the buyer is a private individual and the seller is another private individual. It does not affect dealerships.

• VAT or REBU: if the seller is a dealership, VAT (general scheme) or REBU will apply, depending on the vehicle's origin.

• Declaration of capital gain: if a private individual sells a car for a price higher than the purchase price, they may be required to declare the gain in their personal income tax return.

Conclusion: When must withholding be applied?

In most typical transactions carried out by a multi-brand dealership in Spain:

• It is not mandatory to apply withholding when buying a car from a private individual.

• No withholding is applied when selling to a private individual.

• Withholding will only be necessary if professional services or commissions subject to this mechanism are involved.

Knowing these rules allows you to operate safely and within the legal framework.
