ViDA Explained: How the EU's VAT Overhaul Affects e-Invoicing

Q: What is ViDA?

**ViDA** - VAT in the Digital Age - is the most significant reform to the EU VAT system in over three decades. The European Council formally adopted it on 11 March 2025 as **Council Directive (EU) 2025/516**, and it was subsequently published in the Official Journal of the European Union. The directive touches every VAT-registered business that trades across EU borders, and many that trade only domestically. The driving force behind ViDA is tax fraud. The EU's so-called "VAT gap" - the difference between expected VAT revenue and what governments actually collect - has hovered around €60 billion per year. The Commission estimates that ViDA could recover up to **€18 billion** in additional annual VAT revenue by closing loopholes and increasing transaction visibility. Beyond fraud prevention, ViDA aims to cut red tape for businesses operating in multiple member states and to modernise VAT rules that were written before the platform economy existed. It does this through three distinct pillars, each with its own timeline and scope.

Q: What are the three pillars?

**Pillar 1 - Digital Reporting Requirements (DRR):** This is the pillar that directly affects e-invoicing. It introduces mandatory structured e-invoicing and real-time, transaction-by-transaction reporting for all intra-EU B2B supplies. Businesses will no longer be able to send a PDF and call it an invoice - the data must be machine-readable and reported to the relevant tax authority within a fixed window. **Pillar 2 - Platform economy rules:** Online platforms that act as intermediaries for short-term accommodation rentals and passenger transport services become **deemed suppliers** for VAT purposes. In practice, this means the platform - not the individual host or driver - is responsible for charging and remitting VAT on those transactions. This targets a grey area where billions in revenue was going untaxed. **Pillar 3 - Single VAT Registration:** The existing One Stop Shop (OSS) and Import One Stop Shop (IOSS) schemes are extended so that businesses can handle their VAT obligations across all 27 member states through a single registration in their home country. This eliminates the need for costly, duplicate VAT registrations in every country where a business has customers.

Q: When does it take effect?

The rollout is staggered deliberately. **July 2028** marks the first milestone: the single VAT registration provisions take effect, extending OSS to cover a wider range of supplies. At the same time, member states may optionally apply deemed supplier rules for platforms. This gives both tax administrations and businesses time to update their systems before the heavier obligations land. **January 2030** is when platform economy rules become mandatory - all qualifying platforms must act as deemed suppliers. Six months later, in **July 2030**, the DRR kicks in: all intra-EU B2B invoices must be issued as structured e-invoices conforming to **EN 16931**, and the underlying transaction data must be reported to the tax authority within **10 days** of the invoice date. The final wave lands on **1 January 2035**. By this date, any member state that had a domestic e-invoicing or digital reporting system in place before 2024 must bring it into alignment with the ViDA standards. Countries like Italy, which launched its SDI system in 2019, and Poland, which has been developing KSeF, fall into this category.

Q: What about countries that already have domestic mandates?

Several EU member states did not wait for ViDA. [Italy's SDI](/country/IT) has been running since 2019, and [Poland's KSeF](/country/PL) has been in development for years. These countries, along with any others that had domestic e-invoicing or digital reporting systems operational before 1 January 2024, receive an extended transition period until 2035 to harmonise their systems with the ViDA framework. Countries that introduce new domestic mandates from 2024 onward do not get the same grace period. They must align with ViDA standards from the start. This is already shaping how Belgium, France, and Germany are designing their domestic systems - they know their technical choices must be compatible with the EU-wide DRR that arrives in 2030. Over time, this means convergence. Domestic platforms will need to support EN 16931 and integrate with whatever EU-level reporting infrastructure emerges. Businesses operating across borders can track how different countries are progressing using the [country comparison tool](/compare).

This eliminates the need for costly, duplicate VAT registrations in every country where a business has customers.

When does it take effect?

ViDA rolls out in three waves: 2028, 2030, and 2035.

The rollout is staggered deliberately. July 2028 marks the first milestone: the single VAT registration provisions take effect, extending OSS to cover a wider range of supplies. At the same time, member states may optionally apply deemed supplier rules for platforms. This gives both tax administrations and businesses time to update their systems before the heavier obligations land.

January 2030 is when platform economy rules become mandatory - all qualifying platforms must act as deemed suppliers. Six months later, in July 2030, the DRR kicks in: all intra-EU B2B invoices must be issued as structured e-invoices conforming to EN 16931, and the underlying transaction data must be reported to the tax authority within 10 days of the invoice date.

The final wave lands on 1 January 2035. By this date, any member state that had a domestic e-invoicing or digital reporting system in place before 2024 must bring it into alignment with the ViDA standards. Countries like Italy, which launched its SDI system in 2019, and Poland, which has been developing KSeF, fall into this category.

How does ViDA change e-invoicing?

From July 2030, an intra-EU B2B invoice is only valid if it is a structured e-invoice issued in the EN 16931 format. PDFs, scanned documents, and paper invoices will no longer satisfy the legal requirements for cross-border B2B transactions between EU member states. The invoice must be machine-readable - typically UBL 2.1 or UN/CEFACT CII XML.

Reporting changes too. Instead of periodic VAT returns that summarise totals, businesses must report each transaction individually to their tax authority within 10 days of issuance. This transaction-level, near-real-time reporting is what the Commission calls Digital Reporting Requirements (DRR). It gives governments a much clearer picture of trade flows and makes carousel fraud significantly harder to execute.

There is a direct financial incentive to comply: a valid structured e-invoice becomes a condition for VAT deduction. If a buyer receives a non-compliant invoice, they cannot reclaim input VAT on that purchase. This shifts e-invoicing from a "nice to have" to a hard commercial requirement.

What about countries that already have domestic mandates?

Several EU member states did not wait for ViDA. Italy's SDI has been running since 2019, and Poland's KSeF has been in development for years. These countries, along with any others that had domestic e-invoicing or digital reporting systems operational before 1 January 2024, receive an extended transition period until 2035 to harmonise their systems with the ViDA framework.

Over time, this means convergence. Domestic platforms will need to support EN 16931 and integrate with whatever EU-level reporting infrastructure emerges. Businesses operating across borders can track how different countries are progressing using the country comparison tool.

How should businesses prepare?

The most immediate step is to stop treating PDF invoices as a long-term solution. If your systems cannot generate structured XML in UBL or CII format, that capability gap needs to be on the roadmap now. Audit your current invoicing stack: can your ERP or accounting software produce and receive EN 16931-compliant documents? If not, consider e-invoicing software that can.

Assess your cross-border exposure. If you sell to or buy from businesses in other EU member states, July 2030 is your hard deadline. Map out which of your trading partners are in countries with earlier domestic mandates - you may need to handle structured e-invoicing with them sooner. Belgium's mandate started in January 2026, France is rolling out in 2026, and Germany's phase-in runs from 2025 to 2028.

These domestic mandates are, in effect, practice runs. Treat them as an opportunity to build internal capability, test your systems, and iron out data quality issues before the EU-wide obligation arrives. The overview page and timeline track all upcoming deadlines across countries.
