Reverse charge VAT in Spain: when it applies and how to invoice

Reverse charge VAT shifts the obligation to declare VAT from the seller to the buyer. It sounds like a technicality, but if you invoice services to businesses in other EU countries, you use it every time you issue an invoice. This guide covers when it applies, the exact wording your invoice needs, and how each side of the transaction declares it.

What is reverse charge VAT, and why does it exist?

In a standard transaction, you sell, you charge VAT to the client, and you remit it to the tax authority. The taxable person — the one who owes the obligation to the tax administration — is you, the seller.

Reverse charge flips that order: the buyer becomes the taxable person. You invoice without VAT. They self-assess it in their own return.

The mechanism exists for two practical reasons:

• To avoid forcing the seller to register for VAT in the buyer’s country. If you invoice a German company, it makes no sense for you to register as a VAT taxable person in Germany for a one-off transaction.
• To close off fraud in high-risk sectors. In construction, scrap metal, or certain other materials, the classic scheme — charging VAT and never remitting it — is easy to run through shell companies. Shifting the obligation to the buyer (usually a solvent, traceable business) cuts that fraud off at the root.

Legal basis: Article 84 of Ley 37/1992, Spain’s VAT Act (commonly cited as LIVA). It lists the cases where the taxable person isn’t the one making the supply or performing the service, but the recipient instead.

The most common scenarios

Article 84 LIVA covers several scenarios. The ones you’ll run into most often as a freelancer or small business:

• Services supplied to businesses established in another EU member state (the case covered in detail below). By far the most common if you work with international clients.
• Supplies of goods and services made by someone not established in the territory where the tax applies, under the conditions set out in Art. 84.One.2 LIVA itself.
• Construction work, with or without materials supplied, arising from contracts between the developer and the contractor for land development or the construction or renovation of buildings.
• Certain supplies of unwrought gold or semi-finished gold products (of a fineness equal to or greater than 325 thousandths).
• Supplies of waste and recovered materials (scrap and residues of ferrous and non-ferrous metals, their alloys, slag, and ash).
• Services relating to greenhouse gas emission allowances (including certified emission reductions and emission reduction units).
• Supplies of mobile phones, video game consoles, laptops, and tablets when the total amount of the transaction documented on a single invoice exceeds €10,000 (VAT excluded), in the cases the law defines.

Intra-EU B2B services: the most common case

If you’re a freelancer or small business invoicing services (consulting, development, design, marketing) to a company in another EU country, this is your scenario.

Under the place-of-supply rule, a B2B service is deemed supplied where the recipient is established, not where you are. And Article 196 of EU Directive 2006/112/EC designates that recipient as the person liable for the VAT when the supplier isn’t established in their member state. That’s why you don’t declare the VAT in Spain: the client self-assesses it in their own country, via reverse charge.

Conditions for it to apply:

• The recipient is a business or professional, not a private individual.
• The recipient is established in another EU member state (if they’re in Spain, you invoice standard VAT; if they’re outside the EU, a different regime applies, not reverse charge).
• The recipient holds a valid EU VAT number, verifiable through the European Commission’s VIES system (VAT Information Exchange System).

If all three hold: you invoice without VAT, add the reverse-charge wording, and declare the transaction as an intra-EU supply of services.

The exact wording your invoice needs

A reverse-charge invoice doesn’t show VAT broken out. It shows:

• The taxable base of the service or supply, with no VAT amount.
• The wording “reverse charge” (inversión del sujeto pasivo).
• The client’s EU VAT number (the one you verified in VIES for intra-EU cases).
• Your own Spanish VAT number.

You don’t mark a 0% VAT rate or write “exempt.” Those are different concepts: exempt means the transaction generates no VAT at all; reverse charge means it does generate VAT, but the other side declares it. Mixing them up on the invoice is the most common mistake, and the one that raises the most questions in a tax audit.

How the buyer declares it: output and input VAT

Here’s the part that confuses most people: if nobody charges VAT, who pays it?

Nobody, in practice, if the buyer has full deduction rights. The mechanism works in two steps, within the buyer’s own return:

1. Self-assessment: the buyer calculates the VAT that would apply to the transaction at their country’s rate (or the Spanish rate, if the transaction reverts to Spain) and declares it as output VAT.
2. Deduction: if that purchase qualifies for VAT deduction (standard for a fully operating business), they declare the same amount as deductible input VAT.

The net result is zero: the same amount enters and exits the same box on the return. There’s no cash movement for the VAT on that transaction — which is precisely the point of the mechanism, avoiding a situation where the buyer has to front money and recover it later.

On Spain’s quarterly VAT return (Modelo 303), the output VAT on reverse-charge transactions received goes in boxes 10 and 11 (intra-EU acquisitions of goods and services) or boxes 12 and 13 (other reverse-charge transactions under Art. 84.One.2 and 4 LIVA), and the deductible input VAT goes in the deductible-VAT block (box 28 onwards).

Common mistakes

• Not verifying the EU VAT number in VIES before invoicing. The mistake with the biggest financial consequence: if the number wasn’t valid at the time of the transaction, the risk of the uncollected VAT can fall on you.
• Confusing reverse charge with an exemption and writing “VAT exempt” instead of the correct wording.
• Applying reverse charge to a private individual. Without a business EU VAT number, reverse charge isn’t possible: you charge VAT the ordinary way.
• Forgetting to also declare the transaction on Modelo 349 (the EU transactions recap statement) alongside Modelo 303, when it’s an intra-EU supply of services.
• Applying the construction scenario without checking the exact developer/contractor requirements, or the scrap-metal scenario without confirming the material falls under the regulated category.
• Not keeping the VIES verification record, which is your documentary evidence in a tax review.

A practical case with VIES

You work as a consultant based in Spain and invoice a company headquartered in the Netherlands €4,000 for a project.

1. Before issuing the invoice, you check the VIES system and validate the EU VAT number the client gave you. It comes back valid, with a matching company name. You save the dated screenshot.
2. You issue the invoice for €4,000, with no VAT broken out, carrying the wording “reverse charge” and the client’s Dutch EU VAT number.
3. On your Modelo 303, you declare the transaction as an intra-EU supply of services, with no VAT charged (taxable base, no VAT amount).
4. On that quarter’s Modelo 349, you include the transaction, identifying the client by their Dutch EU VAT number.
5. Your client, on their Dutch VAT return, self-assesses Dutch VAT on that €4,000 as output tax and, if entitled to full deduction, offsets it as input tax in the same box.

You collect €4,000 net. Your client fronts no cash for VAT. And both of you have declared the transaction correctly, each on your own side.

Reverse charge VAT isn’t a special regime you have to apply for: it kicks in automatically once the conditions in Article 84 LIVA are met. All you need to get right is identifying the scenario, verifying the client, and using the correct wording on the invoice.

With your clients and invoices tracked in Frihet, you have the EU VAT number and transaction history on hand to apply reverse charge correctly every time you invoice a business in the EU.
