In the sale and purchase of second-hand cars, every euro counts. For dealerships, especially multi-brand ones in Spain, understanding which expenses can be deducted for tax purposes is key to improving profits and maintaining good financial health. In this article, we clearly and practically explain which costs you can subtract from your income, what the law says, and how tools like Dealcar can help you keep effective control.
What are deductible expenses under Spanish regulations?
A deductible expense is one that is directly related to the dealership's business activity and can be subtracted from gross income to calculate net profit. For it to be tax-deductible, it must meet three conditions:
Be linked to the business activity.
Be supported by invoices or valid documents.
Be recorded in the accounts.
Tax specifics when selling used cars
VAT regime and Special Regime for Used Goods (REBU)
Many dealerships operate under the Special Regime for Used Goods (REBU), which applies when reselling used cars acquired from private individuals or other sellers without the right to deduct VAT. In this case, VAT is not itemised on the sales invoice and is therefore not deductible.
However, if you buy a car from a company with an invoice showing VAT separately, and then sell it under the general regime, you can deduct the input VAT. It is important to understand which regime applies in each transaction.

Cleaning, inspections, ITV, approvals.
As long as they are documented and used for the dealership's activity, they are deductible.
