Spain moves forward with mandatory B2B eInvoicing and reporting

Implementation timeline: First mandatory wave in October 2027

The current launch timeline is:

• October 2026: Order enters into force
• August 2027: Public platform becomes operational
• October 2027: Mandatory for taxpayers with >€8 million turnover
• October 2028: Mandatory for all businesses
• October 2029: Payment status reporting extended to smaller entities

This is still a challenging timetable and could easily mean a further launch slips to 2028.

For organizations in the first wave, the implementation window is now relatively compressed. Your organization should start assessing the implications if the turnover exceeds €8 million.

Please note that the existing SII reporting will continue to apply next to the electronic invoicing obligation.

A Spanish VAT registration does not tell you the full story

The mandate focuses on domestic B2B transactions by established businesses and does not introduce a general B2C eInvoicing obligation.

Having a Spanish VAT registration does not in itself mean that all outgoing invoices will fall within the eInvoicing obligation. The presence of a fixed establishment, the location of the customer and the nature of the transaction are all relevant.

For example, a non-established business whose customers are generally also non-established may have no eInvoicing obligation for its outgoing invoices, while it may still need to receive eInvoices from Spanish suppliers.

Some scenarios still need clarification, including certain transactions carried out by non-established businesses.

Spain combines private platforms with an AEAT solution

Businesses will be able to use private eInvoicing platforms or the public solution managed by the Spanish Tax Agency (AEAT). Invoices must contain structured data based on EN 16931. Currently permitted formats include UBL, CII, EDIFACT and Facturae. Invoices issued through a private platform must also be submitted to the public solution in UBL format. Further technical specifications are still expected, including details on authentication, identification, and communication protocols between platforms.

Life cycle reporting adds another data requirement

Spain is not only changing how invoices are exchanged. Invoice lifecycle information, including full effective payment or rejection, will also need to be reported.

This means organizations need to look beyond their invoice data: where is payment and invoice status information held today, and can it be linked to the original transaction and reported correctly?

Businesses already subject to SII (Immediate Supply of Information), Spain's electronic VAT ledger reporting system, will also need to consider the new requirements alongside their existing Spanish VAT reporting process.

Some international scenarios still need clarification

As mentioned, the scope is not yet fully clear for certain transactions carried out by non-established businesses, including exports to the Canary Islands, Ceuta and Melilla and the rental of Spanish immovable property. For non domestic organizations with different Spanish registrations and transaction types, the scope needs to be assessed per entity and transaction flow rather than simply at country level.

What should you assess now?

You do not need to wait for every technical specification to begin your assessment. For organizations with Spanish operations, three foundational questions are already worth answering:

1. Scope: Which entities, establishments, and transaction flows could be affected?
2. Data: Where are the required invoice, lifecycle, and payment data currently held, and can they be linked and reported correctly?
3. Systems: How will Spain fit into your existing ERP, eInvoicing, and VAT reporting infrastructure?

Assess the impact for your Spanish operations

If your organization's Spanish turnover exceeds €8 million, these assessments should be completed before October 2027.
