In today's globalized world, borders blur for businesses. As a freelancer or SME in Spain, invoicing international clients opens up a universe of opportunities, but it also brings a series of tax complexities that, if not handled correctly, can lead to errors and penalties. With the reference date in 2026 and the imminent arrival of VeriFactu, it's crucial to stay up-to-date.
1. Key: The NIF-IVA and the Register of Intra-Community Operators (ROI)
Before invoicing any client within the European Union (EU), it is *essential* that both you and your client are registered in the Register of Intra-Community Operators (ROI). This will allow you to operate under the reverse charge rule for VAT. You can verify the validity of your client's NIF-IVA through the AEAT's VIES system.
* If both are in the ROI: The invoice is issued without Spanish VAT, and your client self-assesses the VAT in their country (reverse charge).
* If you or your client are not in the ROI: You must apply the corresponding Spanish VAT (21%, 10%, or 4%) on the invoice, as if it were a domestic operation.
2. VAT in International Operations: Intra-Community vs. Extra-Community
VAT application is the cornerstone of international invoicing:
Intra-Community Operations (within the EU)
* Sale of Goods (B2B): If both are in the ROI, the supply is exempt from VAT in Spain (Model 303 and Model 349). The client self-assesses VAT in their country.
* Provision of Services (B2B): Similar to the sale of goods, if both are in the ROI, the service is exempt from VAT in Spain under the reverse charge rule. It is declared in Model 303 and Model 349.
* Sale of Goods or Services (B2C): To final consumers in the EU, Spanish VAT generally applies. However, if you exceed certain sales thresholds in other countries, you might need to register and apply the VAT of each destination country, or use the One Stop Shop (OSS) scheme.
Extra-Community Operations (outside the EU)
* Sale of Goods (Exports): These are exempt from VAT in Spain but require a Single Administrative Document (DUA) for export to prove the goods have left the EU. They are declared in Model 303.
* Provision of Services: Generally exempt from Spanish VAT, as the service is understood to be located where the recipient receives or uses it. It is crucial to indicate the VAT exemption on the invoice (e.g., "Operation exempt under articles 21 and 69 of Spanish VAT Law 37/1992").
3. Essential Content of Your International Invoice
In addition to basic data (your tax information, your client's, date, invoice number, description), an international invoice must include:
* NIF-IVA (if applicable): Both yours and your client's.
* Mention of VAT exemption: "Operation exempt by reverse charge" or "Operation exempt under articles 21 and 69 of Spanish VAT Law 37/1992," as applicable.
* Currency: Clearly specify the currency of the operation.
4. E-Invoicing and VeriFactu: Preparing for the Future (2027)
Fiscal digitalization is advancing rapidly. Mandatory e-invoicing is just around the corner in Spain, and the AEAT's VeriFactu system will be key to ensuring the integrity and traceability of all your invoices.
* From January 1, 2027: It will be mandatory for companies and large businesses.
* From July 1, 2027: The obligation will extend to freelancers and micro-SMEs.
Although invoicing foreign clients may have specific particularities (e.g., if the client is not in Spain), the internal registration of your operations and the issuance of invoices through certified VeriFactu systems will be essential to comply with Spanish regulations. This means your invoicing software must be adapted. Do you need a tool that simplifies your life? Check out our options at Fakturia Prices.
