In the day-to-day running of a used vehicle dealership, not all customers are treated the same by the tax authorities. The tax implications of selling a car to a company are not the same as when you sell it to a private individual. This guide is designed for motor traders and dealerships that want to understand the key tax differences clearly, avoid costly mistakes and professionalise their management.

Introduction to the tax context in vehicle sales

Why is it important to distinguish between a business customer and a private individual?

From a tax perspective, the type of customer determines whether an invoice with VAT must be issued, whether that VAT is deductible, and which tax regime should apply. In addition, businesses can exercise tax rights (such as deducting input VAT), whereas private individuals cannot.

Tax obligations of the dealership

Every dealership is required to issue an invoice for its sales transactions, apply VAT correctly according to the type of transaction, and declare its income in line with the regulations. A mistake in these areas can lead to penalties and tax audits.

Sale to private individuals: obligations and considerations

VAT charged on the sale

When selling to a private individual, VAT must be included in the final price. However, in the case of used vehicles, many dealerships use the Special Scheme for Used Goods (REBU), which allows tax to be charged only on the profit margin.

Simplified invoice vs full invoice

For sales to private individuals, a simplified invoice (similar to a receipt) can be issued if the amount does not exceed €400. But for greater transparency and traceability, it is advisable to issue a full invoice detailing:

• Car price

• Tax base

• VAT applied (if REBU is not used)

• Customer details

What happens if the car was sold on a profit margin?

If the car was acquired without the right to deduct VAT (for example, bought from a private individual), REBU can be applied, which only taxes the margin between purchase price and sale price, not the total. VAT is not itemised on the invoice.

Sale to companies or sole traders: key differences

Deductible VAT and the right to a refund

When the customer is a company or sole trader and the car will be used for business purposes, the VAT can be deducted in their tax return. That is why it is mandatory to issue an invoice showing a VAT breakdown.

Formal invoice requirements

• Full tax details of the company

• Tax ID number and company name

• Tax base and VAT rate applied (normally 21%)

• Date of transaction and signature

Intra-Community supplies or exports

If a vehicle is sold to a company in another EU country with a valid intra-Community VAT number, the transaction may be VAT exempt, provided the requirements for an intra-Community supply are met. The same applies to exports to countries outside the EU.

Practical comparison: selling the same car to a company or to a private individual

Suppose you sell a car purchased for €6,000.

Sale to a private individual (REBU applied):

• Sale price: €8,000 (VAT included in the margin)

• VAT on the margin (€2,000): €347.11

• Net profit before tax: €1,652.89

Sale to a company (invoice with VAT):

• Base price: €8,000 + 21% VAT (€1,680) = €9,680

• VAT charged: €1,680

• Company can deduct that VAT

• Net profit for the dealership: €2,000

Result: selling to companies creates more tax-transparent transactions and may appear more profitable, but it also entails greater control and documentation obligations.

Tax consequences of failing to invoice correctly

Tax authority penalties

Errors such as failing to itemise VAT correctly, applying REBU incorrectly, or not identifying the customer as a company can result in inspections and penalties ranging from 1% to 100% of the undeclared amount.

Reputational and legal risks

A business customer who cannot deduct VAT because of an incorrect invoice may make a claim or even file a complaint. In addition, poor tax management weakens the dealership’s image.

Best practices for professional dealerships

Use of management software adapted to the regulations

Having tools that allow invoices to be issued according to customer type and the correct tax regime to be applied is key to avoiding mistakes.

Specialist tax advice

Having an adviser or accountant who regularly reviews your transactions helps prevent tax contingencies.

Frequently asked questions (FAQs)

What VAT applies when selling a car to a company?

The standard 21% VAT applies if the transaction is not exempt and a full invoice must be issued.

What happens if I sell a car under the margin scheme?

You only pay tax on the profit margin, not on the total. VAT is not itemised on the invoice.

Do I always need to issue an invoice to a private individual?

It is not mandatory, but it is highly recommended. For low amounts, a simplified invoice can be used.

How does selling outside Spain affect tax treatment?

If it is to an EU company with a valid intra-Community VAT number, it may be VAT exempt. If it is outside the EU, it is treated as an export and may also be exempt.
