The UK confirms mandatory e-invoicing from April 2029. All VAT invoices for B2B and B2G transactions must be issued electronically from April 2029. The announcement in the 2025 Budget marks a major step in the country’s digital tax strategy. The reform aims to modernise VAT administration, improve data quality, and reduce manual work for businesses. It aligns the UK with other countries introducing structured e-invoicing and creates a consistent foundation for future compliance. For organisations that want a broader overview of what e-invoicing entails, our e-invoicing solution page explains key concepts and benefits in more detail.
The objective is clear. The government wants to improve productivity, strengthen data accuracy, and modernise VAT administration. Digital processes also help businesses reduce manual work and avoid reporting errors.
Expected roadmap in 2026
Details about formats, exchange methods, and compliance models will follow in the 2026 Budget. The government aims to develop these rules in collaboration with industry groups and business communities. A structured roadmap is planned, similar to previous approaches seen in countries that introduced e-invoicing step by step. The UK has stated that this collaborative approach is important. It intends to support both large organisations and SMEs as they prepare for the transition.
Part of a broader international trend
The UK reform aligns with developments in Europe, where France, Germany, Belgium, Spain, Poland, and others have announced or implemented mandatory e-invoicing frameworks. The trend is clear. Governments want standardised processes, better VAT controls, and efficient cross-border compliance.
For a structured overview of how other European countries approach e-invoicing, you can consult our EU e-invoicing country factsheets. Organisations with a broader international footprint can also review our e-invoicing mandates overview, which summarises key global timelines and obligations.
For international organisations operating in the UK, this move creates an opportunity to harmonise invoice flows and prepare for multi-country e-invoicing strategies.
Key takeaways
Changes companies need to implement to prepare for the 2029 deadline include:
- Reviewing current invoicing and VAT processes to determine readiness for structured e-invoices
- Monitoring the 2026 roadmap to understand technical formats and exchange channels
- Aligning UK preparations with ongoing e-invoicing projects in other regions
- Evaluating internal systems and ERP integrations for future compliance
- Engaging early with solution providers to support testing and onboarding
