In the final week of May 2026, the European Union took one of the most significant steps in the history of VAT harmonisation. The European Commission published its implementation strategy for the VAT in the Digital Age (ViDA) initiative, built around six key implementing acts. These documents set out a concrete roadmap for 2027–2030 and directly affect every company conducting cross-border business within the European Union.
The ViDA initiative, formally adopted by the EU Council on 11 March 2025 and in force since 14 April 2025, represents the deepest reform of European VAT in over two decades. Its objectives are clear: tighten tax collection, combat carousel fraud, and bring European tax law in line with the realities of the digital economy.
Until now, ViDA operated primarily as a legislative framework. The announcement of six implementing acts signals that it is moving decisively from legislation into live implementation.
The six implementing acts address three interconnected areas that together form a new VAT ecosystem across Europe.
Digital Reporting Requirements (DRR) — From 1 July 2030, B2B transactions between VAT-registered businesses in different EU member states will need to be reported digitally in near real time. The invoice ceases to be a document processed reactively weeks after a transaction — it becomes data transmitted to the tax authority almost immediately upon issuance. For businesses, this means full integration of ERP and accounting systems with the reporting infrastructure will be non-negotiable.
Modernisation of VIES — The VAT Information Exchange System will undergo a comprehensive overhaul. The aim is faster and more precise verification of counterparty VAT registrations, significantly reducing the risk of transacting with fictitious or unregistered entities.
Expansion of the One Stop Shop (OSS) — The OSS, which allows businesses to settle VAT obligations across multiple EU countries through a single registration, will be extended to cover additional transaction categories. For companies selling digitally or providing cross-border services, this means further simplification of compliance obligations.
The six implementing acts define the following key milestones:
By 31 December 2026, all member states must transpose the ViDA directive into national law. This deadline is already influencing the pace of legislative work across EU countries — including Poland, the Czech Republic, and Slovakia.
From 1 July 2028, expanded OSS provisions enter into force, covering new transaction categories and types of suppliers.
From 1 July 2030, cross-border B2B e-invoicing becomes mandatory across the EU, with a near-real-time reporting requirement. Invoices must comply with the European standard EN 16931.
By 1 January 2035, all national e-invoicing systems must be harmonised with EU-wide standards.
Poland is currently at the forefront of European e-invoicing — mandatory KSeF has been in force since 1 February 2026 for large taxpayers and since 1 April 2026 for all remaining businesses. This gives Polish companies a head start in adapting to the requirements of ViDA.
However, ViDA goes well beyond domestic invoicing systems. The key challenges for businesses are as follows.
Companies exporting to other EU countries or importing from EU-based suppliers must prepare for digital reporting of cross-border transactions from 2030 onwards. ERP and financial systems should already be factoring this into their development roadmaps.
Compliance and IT teams should monitor the progress of ViDA transposition in partner countries — each member state may implement the EU requirements in slightly different ways, particularly regarding data formats and reporting infrastructure.
Businesses operating across multiple EU jurisdictions should consider auditing their current invoicing processes for ViDA readiness, especially in the areas of data formats and system integration.
The announcement of six ViDA implementing acts is the moment at which the European VAT system moves from theory to a concrete implementation project — with dates, standards, and penalties. Companies that begin preparations today — analysing their systems, processes, and data infrastructure — will be far better positioned than those who wait until the last moment.
The year 2030 may seem distant. Yet the experience of KSeF implementation in Poland, mandatory e-invoicing in Belgium, and the German mandate all point to the same lesson: system integrations, staff training, and process adjustments take considerably longer than initially anticipated.
