Frequently asked questions
Is e-invoicing mandatory in Spain?
E-invoicing has been mandatory in Spain for B2G (business-to-government) transactions since 2015. Mandatory B2B e-invoicing is now being introduced through the “Ley Crea y Crece” reform, with a phased rollout expected over the coming years. While the draft framework has been published, the final technical regulations and enforcement dates are still being confirmed by the Spanish authorities.
Expected timeline:
- October 2027 — Companies and professionals with an annual turnover exceeding €8 million must send and receive e-invoices and report invoice status: accepted/rejected and full payment.
- October 2028 — All businesses must send and receive e-invoices. Companies with an annual turnover less than €8 million must report invoice status: accepted/rejected and full payment.
- October 2029 — Professionals with an annual turnover less than €8 million must report invoice statuses: accepted/rejected and full payment
When will e-invoicing become mandatory for B2B transactions in Spain?
Mandatory B2B e-invoicing in Spain is expected to be introduced in phases:
- Large companies (annual turnover above €8 million): expected from 2027
- SMEs and self-employed businesses: expected from 2028
The final implementation dates will depend on the publication of the technical regulations under the “Ley Crea y Crece” framework.
What invoice format will be used for e-invoicing in Spain?
Spain’s public platform is expected to standardize e-invoices using UBL format compliant with the EN16931 European standard. E-invoices will require a digital signature and PDF attachments will not be accepted as compliant invoices.
Invoice content may vary depending on how the invoice is issued: Invoices created manually through the public portal may include only the mandatory legal information. Invoices submitted through a company’s own software may contain additional business information.
The final technical specifications for mandatory B2B e-invoicing are still being finalized by the Spanish authorities.
Will invoice status reporting be mandatory in Spain?
Yes. Spain’s upcoming B2B e-invoicing framework will require mandatory reporting of key invoice statuses through the public e-invoicing platform.
The mandatory invoice statuses will include:
- Accepted (+ date)
- Rejected (+ date)
- Paid (+ date)
Which EU countries have mandatory e-invoicing?
Several EU countries have already introduced mandatory e-invoicing requirements, including.
- Italy: Mandatory nationwide B2B e-invoicing has been in force since 2019 through the SDI platform.
- Poland: Mandatory e-invoicing through the KSeF platform was introduced in February 2026 for large companies and April 2026 for all VAT-registered businesses.
- Belgium: Mandatory B2B e-invoicing using Peppol was introduced in January 2026.
- Romania: Mandatory B2B e-invoicing through the RO e-Factura system has been applied since 2024.
Other EU countries, such as Spain and Germany, are also moving toward broader e-invoicing mandates.
France is currently implementing mandatory e-invoicing and e-reporting through a phased rollout planned for September 2026 and September 2027.
What is the difference between Spain’s B2B e-invoicing reform Ley Crea y Crece and Veri*factu?
Veri*factu is a Spanish anti-fraud regulation that requires invoices to be generated through certified software to guarantee invoice integrity, authenticity and traceability. The regulation mainly targets small businesses (with less than €6 million in revenue) and aims to extend Spain’s existing SII tax reporting system to smaller companies.
By contrast, the “Ley Crea y Crece” reform focuses specifically on mandatory B2B electronic invoicing and invoice exchange requirements between businesses.
