Why warranty accounting matters more than it seems
A warranty sold alongside a vehicle is not just an added value for the customer: it is a future obligation that the dealership assumes at the time of sale. If this obligation is not correctly reflected in the accounting, the business presents a financial result that is more optimistic than reality, and the repair costs that arrive months later have no accounting coverage.
From a tax perspective, the warranty also has implications: the revenue can be recognized on a deferred basis if it is invoiced separately, and the cost of covered repairs is only deductible if it is properly provisioned or actually occurs. Without this correct treatment, the Tax Agency can question the deductibility of these expenses in an audit.
Furthermore, the commission that the dealership receives when acting as an intermediary for an external warranty is a service subject to VAT that is not always declared. This is one of the most common errors because it is perceived as an "ancillary" income to the car sale.

The three possible scenarios: which one applies to your business
Before looking at the journal entries, it is necessary to identify which situation each transaction falls into. The accounting and tax treatment varies completely according to the scenario.
Scenario 1: the dealership offers its own warranty, directly assuming the cost of any repairs that may arise. The warranty is included in the vehicle price, without being invoiced separately.
Scenario 2: the dealership offers its own warranty but invoices it as an additional service, apart from the vehicle price.
Scenario 3: the dealership acts as an intermediary for an external warranty company. The dealership does not assume the risk of repairs; the insurance company or warranty firm does. The dealership charges a commission or a margin.
Most small and medium-sized dealerships operate in scenario 1 or scenario 3. Scenario 2 is more common in franchise networks or dealerships with their own structured warranty programs.
Case 1: Own warranty included in the vehicle price
This is the most common scenario and the one that generates the most accounting errors, precisely because of its apparent simplicity.
The accounting logic. The total price of the vehicle includes a warranty commitment. A part of this revenue does not correspond to the delivery of the car, but to a future service (the repairs covered by the warranty). That part must be recognized as deferred revenue and, simultaneously, as a provision to cover the expected expense.
Numerical example: sale of a vehicle for €10,000 with warranty included. Based on its history, the dealership estimates that the average cost of warranty repairs per vehicle is €350.
Entry at the time of sale:
Account | Debit | Credit |
|---|---|---|
(430) Customers | €10,000 | |
(700) Sales of goods |
Entry for the provision:
Account | Debit | Credit |
|---|---|---|
(650) Losses on warranties | €350 | |
(141) Provision for warranties |
When a warranty repair actually occurs (for example, €280):
Account | Debit | Credit |
|---|---|---|
(141) Provision for warranties | €280 | |
(572) Banks |
If at the end of the warranty period there is unused provision left over, it is reversed: the provision is cleared and registered as income.
Taxation. VAT is settled on the total sale price (€10,000) in the quarter of the operation. The accounting provision of €350 is tax-deductible if it is based on objective, documented criteria (loss history, reasonable estimations). A provision without a documentary basis can be questioned by the Tax Agency as an unjustified expense.
Case 2: Own warranty invoiced separately
When the warranty is invoiced separately from the vehicle, it becomes an independent service provision with its own accounting treatment.
The accounting logic. The warranty revenue is not accrued at the time of the invoice, but over the coverage period. Applying the accrual principle, the €500 of a 12-month warranty is recognized as revenue at a rate of €41.67/month.
Numerical example: sale of vehicle for €10,000 plus additional warranty of €500 (12 months).
Vehicle sale entry (standard):
Account | Debit | Credit |
|---|---|---|
(430) Customers | €10,000 | |
(700) Sales of goods |
Entry upon collecting the warranty:
Account | Debit | Credit |
|---|---|---|
(430) Customers | €605 (€500 + 21% VAT) | |
(485) Deferred income | ||
(477) Output VAT |
Monthly entry during the 12 months (€41.67/month):
Account | Debit | Credit |
|---|---|---|
(485) Deferred income | €41.67 | |
(705) Provision of services |
Taxation. VAT is accrued at the time of invoicing (it is settled in full in the quarter of issue), even though in accounting terms the revenue is recognized on a deferred basis. This discrepancy between the accounting recognition of income and the VAT settlement is common in services with multi-period coverage and does not pose any problem if managed correctly.
Case 3: Third-party warranty — agent vs. reseller
When the dealership does not assume the risk of repairs but instead acts as a distribution channel for an external warranty company, there are two possible situations with different treatments.
Situation A — The dealership acts as an agent (on behalf of another). The warranty company invoices the customer directly. The dealership only receives a commission for having arranged the sale of the service. The dealership's income is exclusively that commission.
Entry for commission received (example: €120 + VAT):
Account | Debit | Credit |
|---|---|---|
(572) Banks | €145.20 | |
(705) Provision of services | ||
(477) Output VAT |
Situation B — The dealership resells the warranty (in its own name). The dealership charges the customer the full price of the warranty (for example, €500) and then pays the external company its share (for example, €380). The margin of €120 is the dealership's profit.
Entry for charge to the customer:
Account | Debit | Credit |
|---|---|---|
(430) Customers | €605 (€500 + 21% VAT) | |
(705) Provision of services | ||
(477) Output VAT |
Entry for payment to the warranty company:
Account | Debit | Credit |
|---|---|---|
(623) External services | €380 | |
(472) Input VAT | €79.80 | |
(572) Banks |
Why this distinction matters. If the dealership acts in its own name, VAT is calculated on the total charged to the customer (€500). If it acts on behalf of another, VAT only applies to the commission (€120). The difference can be significant in terms of volume and also determines how it is reflected in Form 347. This distinction must be defined in the contract with the warranty company.

VAT on warranty extensions: when it applies and at what rate
Vehicle warranties are services subject to the standard VAT rate of 21%, regardless of whether they are sold together with the vehicle or separately, and regardless of whether the provider is the dealership or an external firm.
There is no VAT exemption applicable to vehicle warranties. The exemption that applies to insurance (Article 20.One.16 of the VAT Law) only applies to insurance contracts formally constituted under insurance regulations. Commercial warranties offered by dealerships do not have that status unless they are formalized as insurance policies by an authorized insurance entity.
A warranty sold by the dealership itself, even if it is called "warranty insurance," is subject to 21% VAT if it is not backed by an actual insurance policy. If the dealership distributes warranties from a legally established insurer (not just a warranty company), the premium may be exempt from VAT. It is advisable to review this point with your tax advisor if you distribute third-party warranties, because the treatment can change the retail price and the competitiveness of the product.
For more details on which expenses are deductible in a dealership's activity and how they affect general taxation, you can consult the guide on deductible expenses for second-hand car dealerships.
Tax deductibility of warranty expenses
Expenses for repairs carried out under warranty are deductible in Corporation Tax or Personal Income Tax (IRPF) when they actually occur. The problem is the time lag: the sale occurs in year N, but the repair may occur in year N+1 or N+2.
For the expense to be deductible in the year of the sale (or in any year prior to the actual repair), there must be a duly justified accounting provision. The justification criteria accepted by the Tax Agency (AEAT) are: the dealership's own historical claims record (percentage of vehicles that have generated warranty costs in previous years), sector statistics, or technical criteria documented by the after-sales service.
A provision calculated "by rule of thumb" without supporting documentation can be rejected as a deductible expense. A provision calculated systematically, reviewed each financial year, and adjusted to the historical reality of the business is very difficult to question.
If the dealership does not set up a provision and simply deducts the warranty expenses when they occur, the treatment is simpler but it can distort the accounting result of each financial year.
For a complete overview of dealership taxation, you can review the tax guide for dealerships.
Documentary obligations in warranty transactions
Warranty contract signed by the customer. Regardless of the scenario (warranty included or invoiced separately), the customer must receive a document specifying the duration, coverage, exclusions, and procedure for making a claim. Without that document, the dealership will find it difficult to defend itself if the customer claims for something that was not covered.
Invoice if the warranty is charged separately. If the warranty is invoiced independently, a correct invoice must be issued with the applied VAT rate and the indicated coverage period.
Record of warranty incidents. Every repair carried out under warranty must be recorded: description of the problem, diagnosis, cost of the repair, date, and vehicle details. This record serves as the support for the accounting provision and the receipt for the deductible expense.
Contract with the external warranty company. If the dealership distributes third-party warranties, the contract governing the relationship (agent vs. reseller, payment terms, liabilities) must be available for any tax audit. To see how warranty documentation fits into the complete file for each vehicle, you can consult the guide on mandatory documentation in every buying and selling transaction.

Frequently asked questions
Do I have to apply VAT to the warranty even if it is included in the price of the car?
Yes. The warranty included in the price is part of the total taxable base on which the VAT is calculated. There is no basis for artificially separating the price of the warranty to reduce the taxable base if both are charged together as a single price.
When can I deduct the expense of a warranty repair?
In the financial year in which the repair occurs, if you have not set up a provision. Or in the year of the sale (and subsequent years), if you have established a justified accounting provision. The provision brings forward the deductibility of the expense to the year of the sale.
What happens if the external warranty is formalized as an insurance policy?
If the warranty company is a legally established insurer and the warranty is formally an insurance policy, the premium may be exempt from VAT according to Article 20.One.16 of the VAT Law. In that case, the dealership distributing the policy acts as an insurance intermediary and the tax treatment of its commission also varies. This is a scenario that requires specific review with your tax advisor.
Does the warranty affect the taxable base of the REBU?
If the vehicle is sold under the REBU scheme with the warranty included in the price, the selling price for the purpose of calculating the margin is the total price charged to the customer, including the warranty. It is not possible to reduce the selling price for REBU purposes by arguing that part of the price corresponds to the warranty.
