Send Invoice in Spain

To comply with Spanish law, freelancers must issue invoices for all services rendered and goods sold, adhering to specific regulations set by the Agencia Tributaria (AEAT). A significant upcoming change is the Verifactu system, which mandates that all invoicing software used by businesses and freelancers must be certified and capable of sending invoice records to the AEAT in real-time or near real-time. This system aims to combat tax fraud and is expected to be fully implemented by July 1, 2025, though some sources indicate a potential delay or phased approach. Freelancers should ensure their chosen invoicing solution will be Verifactu compliant well in advance of the deadline.

Invoice numbering is another critical aspect; invoices must follow a sequential numbering system without gaps, typically starting from 1 each year or maintaining a continuous sequence. For instance, "2024/001," "2024/002," or simply "001," "002" if the sequence is continuous across years. Additionally, all invoices, simplified invoices, and credit notes must be stored for a minimum of four years for tax purposes, though it's often recommended to retain them for six years to cover potential commercial disputes. This storage can be digital, provided the digital copies are legible and accessible.

Every Spanish invoice, regardless of the client type, must contain a set of mandatory details to be legally valid. These include:

• Invoice Number: A unique, sequential number.
• Date of Issue: The date the invoice is created.
• Date of Service/Operation: If different from the issue date.
• Seller's Details: Full name or company name, tax identification number (NIF/CIF), and full address.
• Client's Details: Full name or company name, tax identification number (NIF/CIF), and full address. For B2C invoices, the client's NIF may not be strictly mandatory unless they request it or the amount exceeds €3,000.
• Description of Services/Goods: A clear and detailed description.
• Unit Price: The price per unit before tax.
• Quantity: The number of units.
• Tax Base: The total amount before VAT and IRPF.
• Applicable VAT Rate and Amount: The percentage and calculated amount.
• IRPF Withholding (if applicable): The percentage and calculated amount.
• Total Amount Payable: The final amount after all taxes and deductions.

While B2B and B2G invoices generally require all these details, B2C invoices can sometimes be simplified invoices for amounts under €400 (or €3,000 in specific cases), requiring fewer details, such as omitting the client's NIF. A common mistake is forgetting to include the client's NIF for B2B transactions, which can lead to issues for both parties.

Understanding VAT (Impuesto sobre el Valor Añadido) and IRPF (Impuesto sobre la Renta de las Personas Físicas) is crucial for Spanish freelancers. VAT is a consumption tax, and the standard rate in Spain is 21%, though reduced rates of 10% and 4% apply to specific goods and services. If you are a freelancer providing services to Spanish clients, you generally need to charge VAT and then declare and pay it to the AEAT quarterly. However, some activities are exempt from VAT, such as certain educational or medical services.

IRPF is a personal income tax, and as a freelancer, you often need to apply a withholding (retención) on your invoices to other Spanish businesses or professionals. The general IRPF retention rate for new freelancers is 7% for the first two and a half years of activity, after which it typically rises to 15%. This withheld amount is then paid by your client directly to the AEAT on your behalf, acting as an advance payment on your annual income tax.

For international clients, the rules differ significantly. For clients within the EU (B2B), you generally apply the reverse charge mechanism, meaning you don't charge VAT, and the client accounts for VAT in their own country. You must be registered in the VIES (VAT Information Exchange System) to do this. For non-EU clients, neither Spanish VAT nor IRPF is typically applied, as the service is considered to be rendered outside of Spain for tax purposes.

Freelancers in Spain frequently encounter several pitfalls when creating invoices, which can lead to compliance issues and potential penalties. One of the most frequent errors is incorrectly applying VAT or IRPF, particularly when dealing with international clients or misunderstanding the applicable rates. Forgetting to include the client's NIF for B2B transactions or using an incorrect NIF is another common oversight that can invalidate an invoice for tax purposes.

Misunderstandings about credit notes are also prevalent. A credit note (nota rectificativa) is used to correct or cancel a previously issued invoice, for instance, due to a pricing error, a returned product, or a service cancellation. It must reference the original invoice number and clearly state the reason for the adjustment. It is crucial not to simply delete or modify an existing invoice; a credit note is the correct legal instrument for adjustments.

To ensure compliance, best practices include:

• Double-checking all mandatory details before sending any invoice.
• Verifying client NIFs for B2B transactions, especially for EU clients via the VIES system.
• Staying updated on VAT and IRPF rates and any changes in legislation.
• Using a reliable invoicing system that helps automate compliance checks and can adapt to future regulations like Verifactu.
• Maintaining meticulous records of all invoices issued and received for the legally required period.
