What are the invoice requirements for autonomos?

There are strict invoice requirements that are set by the tax department. This is advice on how to format an invoice.

By January 1 2027 a legislated system called VeriFactu will be mandatory for all companies. From 1 July 2027 all autónomos will also have to comply. You can read more about it in this VeriFactu article. It was originally going obligatory after July 1 2026 but unsurprisingly, there are delays.

For now, if you’re self-employed in Spain, your invoice needs to meet certain legal requirements. Here’s what you must include:

Spanish invoice requirements for autonomos:

  1. Invoice number that is sequential and unique (e.g. 2025-001)
  2. Date of issue
  3. Your full name and NIE/NIF
  4. Your registered address
  5. Client’s name and NIF/VAT number is required for businesses and professionals
  6. Client’s address
  7. Service or product description that is clear and specific
  8. Date of service if the date is different from issue date
  9. Base amount is the amount before taxes
  10. IVA (VAT) is typically 21%, unless exempt or special rate (see link at bottom)
  11. IRPF if applicable (usually 15%, or 7% if you’re newly registered)
  12. Total to pay calculated = Base + IVA – IRPF

Recommended extras to include:

  • Bank details like your IBAN and BIC/SWIFT for international clients
  • Payment method e.g. bank transfer, PayPal, Wise
  • Payment terms e.g. “Payment due within 15 days”

If you are registered for intra-community VAT:

  • Your EU VAT number (if you’re registered in the ROI and invoicing an EU client)
  • The client’s EU VAT number (if the reverse charge applies and they’re also registered in VIES)
