Approval of Mandatory E-Invoicing in Spain

On the 24th of March 2026, Spain’s Council of Ministers approved a Royal Decree (Law 18/2022), resulting in the implementation of mandatory electronic invoicing for B2B transactions between businesses and professionals in Spain. This is part of Spain’s transition to meet the EU’s e-invoicing requirements under the VAT in the Digital Age (ViDA) initiative in the coming years.

This implementation in Spain will take the form of a phased rollout, beginning upon the publishing of the implementing Ministerial Order by the Ministry of Finance which is expected to be published around July 2026. From this date, businesses with an annual turnover greater than €8 million are required to comply with these requirements within 1 year. Whilst all other businesses will have 2 years to comply.

All e-invoices must comply with structured formats to allow for the automated processing and the transparent review of the invoices status from start to finish. This is to provide the Spanish tax authority with complete visibility over compliance and to help combat fraud.

The Spanish tax authority has outlined that there will be two different platforms through which businesses in Spain will be able to exchange e-invoices.

• A Free Public Platform – this platform will be developed and released by the Spanish tax authority which will be accessible to all businesses in Spain.
• Pre-Existing Private Platforms – any pre-existing private platform can be used so long as they are interoperable and interconnected with other platforms in Spain.

For many businesses, these recent changes add another layer of complexity and challenges to VAT compliance, such as adapting existing invoicing systems, ensuring data accuracy, and aligning with evolving technical standards to avoid non-compliance with their new e-invoicing obligations in Spain.

Understand your Obligations and Implement Forward Facing Solutions

Businesses should understand what new obligations will be applicable in Spain. This depends on your business’ activities and annual turnover which should be assessed as soon as possible considering the upcoming rollout in order to give your business the sufficient time to adapt to any required changes which are required to comply with new e-invoicing obligations.

Addressing these changes requires more than just a quick technical fix. Businesses need a structured and scalable approach to e-invoicing and VAT compliance. By reducing reliance on manual input, businesses can improve accuracy, ensure consistency, and respond more effectively to regulatory changes.

One thing is certain, taking a proactive, forward-facing approach to e-invoicing requirements allows businesses to stay ahead of regulatory developments and avoid non-compliance, which may result in significant penalties.
