VAT Liability vs VAT Exemption in Spain: Key Differences and the Legal Requirement to State the Exemption on the Invoice
There are two ways to issue an invoice without VAT in Spain: because the transaction is outside the scope of VAT, or because it is within scope but exempt. These are different situations with different fiscal consequences, and confusing them can result in invalid invoices, loss of input VAT deduction rights and problems in a tax inspection. Furthermore, when an exemption applies, the law requires the invoice to state the specific legal basis for that exemption. This guide explains the difference, what exemptions exist and exactly what must appear on the invoice.
The VAT conceptual map: taxable, exempt and non-taxable
To understand exemptions properly, we must start from the structure of the tax. VAT covers the supply of goods and services carried out by businesses and professionals in the course of their economic activity (Article 4 of Law 37/1992). But not all transactions carried out by a business or professional are taxed the same way — not all of them are even taxed.
There are three basic categories:
Taxable and non-exempt transactions: within the scope of VAT, subject to the applicable rate (21%, 10% or 4%). The business charges VAT to the customer, declares it and has the right to deduct input VAT on its purchases.
Taxable but exempt transactions: within the scope of VAT — the taxable event occurs — but the law releases them from payment of the tax. The business does not charge VAT to the customer, but with important consequences for its right to deduct.
Non-taxable transactions: outside the scope of VAT by definition. No taxable event arises. The tax simply does not exist for that transaction.
The fundamental distinction: taxable scope vs exemption
This distinction is not merely academic. It has very concrete practical consequences.
Non-taxable transactions: outside VAT entirely
Non-taxable transactions are regulated in Article 7 of Law 37/1992. These are transactions that, even when carried out by a business or professional, do not constitute a taxable event under VAT because the law expressly excludes them from its scope. Key examples include:
- The transfer of a business or branch of activity as an autonomous economic unit (Art. 7.1.º VAT Law): selling a business as a going concern is not subject to VAT.
- Services provided by natural persons under an employment or administrative relationship (Art. 7.6.º VAT Law): an employee's salary does not carry VAT because it is not a business service.
- Free samples of goods without commercial value (Art. 7.2.º VAT Law).
- Transfers of money as consideration or payment — interest payments, for example (Art. 7.12.º VAT Law).
- Services provided directly by Public Administrations without consideration or in exchange for taxes or levies (Art. 7.8.º VAT Law).
- Administrative concessions and authorisations in general (Art. 7.9.º VAT Law).
For these transactions, no VAT invoice is issued because the tax does not exist. If the business issues an invoice, the absence of VAT must be reflected with the notice: "Transaction not subject to VAT under Article 7 of Law 37/1992."
Taxable but exempt transactions: within VAT scope, but released
Exempt transactions are within the scope of VAT — the taxable event does occur — but the law, for reasons of fiscal or social policy, releases them from payment. The main regulation is in Articles 20 to 27 of Law 37/1992.
This distinction has a direct impact on the partial exemption (pro-rata rule): if a business simultaneously carries out both taxable non-exempt operations and exempt operations, its right to deduct input VAT is reduced proportionally. If a transaction were non-taxable (Art. 7), it would not enter the pro-rata calculation at all. Misclassifying the two can distort the VAT return.
What exemptions exist: the main categories of Article 20 VAT Law
Article 20 of Law 37/1992 governs exemptions on domestic transactions. These are restricted exemptions: the business does not charge VAT, but nor can it deduct the input VAT on goods and services it acquires to carry out those exempt operations.
The exemptions fall into broad categories:
Healthcare and welfare services (Art. 20.One.2.º to 4.º)
Exempt: hospitalisation and healthcare services, medical and health services provided by medical or healthcare professionals, and social welfare services. Includes hospitals, clinics, doctors, dentists (with nuances), social workers and day care centres.
Education and training services (Art. 20.One.9.º)
Exempt: education of children and young people, childcare and custody, school, university and postgraduate education, and vocational training and retraining provided by public-law bodies or authorised private entities. The key is that the entity must be authorised or recognised: a freelancer providing non-subsidised training generally charges VAT unless they fall within a specific exception.
Cultural and sporting services (Art. 20.One.13.º to 15.º)
Exempt: cultural services provided by public bodies or non-profit entities, theatrical, musical and circus performances by these entities, and sporting and recreational services provided to natural persons by non-profit entities or sports federations.
Financial and insurance services (Art. 20.One.16.º to 18.º)
Exempt: insurance and reinsurance operations, brokerage services in financial transactions, and a wide range of financial operations including deposits, loans, guarantees, transfers, foreign exchange transactions and securities transactions. This exemption is broad but has exceptions (portfolio management, for instance, may be taxable).
Property transactions (Art. 20.One.20.º to 23.º)
Exempt: the second and subsequent sale of buildings (the developer's first sale is taxed at the reduced 10% rate), the rental of residential property for use as a home, and the creation and transfer of rights of use over non-buildable land. The rental of commercial premises is taxable and non-exempt (21% rate).
Important: the taxpayer may waive the exemption for transfers of land and buildings (Art. 20.Two VAT Law), converting the transaction into taxable and non-exempt, triggering the reverse charge mechanism.
Full exemptions: exports and intra-Community transactions (Arts. 21–25 VAT Law)
These are a fundamentally different type of exemption. Exports (Art. 21) and intra-Community supplies of goods (Art. 25) are exempt, but the business retains the right to deduct input VAT. For this reason they are called "full exemptions": the effect is equivalent to a 0% rate applied at destination, rather than a restriction on the right to deduct.
The legal obligation: stating the exemption on the invoice
This is the practical core of the issue. Article 6.1.j) of Royal Decree 1619/2012 (Invoicing Regulations) is unambiguous:
Every invoice must contain, among its mandatory items: "Where the transaction documented on the invoice is exempt from Value Added Tax, reference to the applicable legal provisions."
This means that writing "VAT exempt" or simply omitting the tax is not enough. The invoice must identify the specific legal provision that justifies the exemption.
What exactly must appear on the invoice
The correct practice — and what the AEAT requires in its reviews — is to include the reference as precisely as possible. Examples:
| Type of transaction | Correct invoice wording |
|---|---|
| Medical service | "VAT exempt. Art. 20.One.3.º Law 37/1992" |
| Educational service | "VAT exempt. Art. 20.One.9.º Law 37/1992" |
| Residential property rental | "VAT exempt. Art. 20.One.23.º Law 37/1992" |
| Financial operation (loan) | "VAT exempt. Art. 20.One.18.º Law 37/1992" |
| Insurance | "VAT exempt. Art. 20.One.16.º Law 37/1992" |
| Export | "VAT exempt. Art. 21 Law 37/1992" |
| Intra-Community supply | "VAT exempt. Art. 25 Law 37/1992" |
| Non-taxable transaction (Art. 7) | "Transaction not subject to VAT. Art. 7 Law 37/1992" |
Where the VAT Law refers to a European Directive, it is also admissible to cite the relevant article of Directive 2006/112/EC alongside the domestic provision.
What happens if the reference is not included?
Omitting the legal reference on an exempt invoice has direct consequences:
1. The invoice is formally invalid as a supporting document, for non-compliance with Art. 6.1.j) of RD 1619/2012. This may prevent the recipient from using it as accounting and fiscal support.
2. Risk of inspection and penalty: the AEAT has systematically identified this error in reviews of subsidised training files (where the issuer invoices as exempt under Art. 20.One.9.º but without citing the provision) and in property transactions. The absence of the reference can be interpreted as a sign that the issuer was uncertain whether the exemption applied.
3. Impact on the recipient: if the recipient has recorded the invoice as supporting an exempt transaction and the invoice turns out to be formally invalid, they may be required to regularise their tax position.
Exemptions in the new e-invoicing framework
With the entry into force of RD 238/2026 (mandatory B2B e-invoicing), exempt invoices must also be issued in structured format (Facturae, UBL or CII). The exemption reference field (or non-taxable reason) has a specific element in the XML schema of these formats with predefined values.
Under the RRSIF and VeriFactu (RD 1007/2023), the invoicing record generated by the SIF includes the type of transaction, and the correct classification between exempt and non-taxable operations directly affects which records are transmitted (or retained) for the AEAT. A SIF that does not correctly distinguish between exemption and non-taxable status may generate incorrect records that lead to information requests from the Tax Authority.
Restricted exemptions vs full exemptions: the impact on VAT deduction
This is the most important distinction from the business's tax management perspective:
Restricted exemptions (most of those under Art. 20: healthcare, education, insurance, second-transfer buildings, residential rental): the business does not charge VAT, but cannot deduct input VAT on purchases related to those exempt activities. Where both exempt and non-exempt operations are carried out, the pro-rata rule applies to determine what proportion of input VAT can be deducted.
Full exemptions (exports, intra-Community supplies): the business does not charge VAT, but can deduct input VAT. These are "exemptions with the right to deduct", effectively zero-rating at destination. Economically, the effect for the business is equivalent to a 0% rate.
Frequently asked questions: VAT scope, exemptions and invoicing
Does a freelancer providing private tuition need to charge VAT?
It depends. If the tuition falls within the scope of children's or young people's education, school, university or vocational training provided by an authorised entity, the Art. 20.One.9.º exemption may apply. If the classes are general private tuition not covered by those categories, the service is taxable and non-exempt. The key is whether the activity and the entity meet the exemption's requirements.
Does a doctor issuing invoices need to include VAT?
Generally no, if the services are healthcare provided by a medical professional (Art. 20.One.3.º VAT Law). But if the doctor provides expert reports, judicial assessments or activities not strictly of a healthcare nature, those services may be taxable and non-exempt. The exemption is not automatic simply by virtue of being a doctor: it depends on the type of service provided.
Is the rental of commercial premises exempt from VAT?
No. The rental of premises for business activities is taxable and non-exempt at the standard 21% rate. Only the rental of residential property for use as a home (Art. 20.One.23.º VAT Law) is exempt. The error of issuing invoices without VAT for commercial premises is common and has consequences for declared VAT.
What is the difference between writing "exempt" and citing the article on the invoice?
The difference is that only the latter satisfies the legal obligation. Article 6.1.j) of RD 1619/2012 requires reference to the applicable legal provisions, not a generic note. Writing only "VAT exempt" without citing the provision makes the invoice formally incomplete.
Do non-taxable transactions also require a reference on the invoice?
Yes, although Art. 6.1.j) specifically mentions exemptions. The recognised best practice — and what the AEAT's models require — is to include the reference to Article 7 of Law 37/1992 when the transaction is non-taxable. Without that reference, the invoice is insufficiently informative for the recipient and for any potential inspection.
Can a business waive a VAT exemption?
Only in specific prescribed cases. The most relevant is the waiver of the exemption for property transactions (Art. 20.Two VAT Law): it allows the seller of a second-transfer building to opt to charge VAT (with reverse charge), which is advantageous when the buyer has full right to deduct. Outside this specific case, the exemptions under Art. 20 are non-waivable.
Conclusion: the exemption reference is not a formality — it is a legal requirement
Issuing an invoice without VAT because the transaction is exempt is not sufficient on its own. The law requires knowing why it is exempt and stating it on the invoice, citing the specific article of the VAT Law that justifies the exemption.
This obligation, in force since RD 1619/2012, gains new relevance with e-invoicing and the RRSIF: in structured formats, the exemption basis is a field with predefined values, not free text. If the software does not handle it correctly, the invoicing record may be incorrect.
For advisors, accountants and businesses, periodically reviewing whether the exempt invoices issued or received comply with Art. 6.1.j) of RD 1619/2012 is a basic internal control task that can prevent major problems in an inspection.
