The Scale of the Problem
In 2023, EU Member States collected €1,223 billion in VAT revenue — making it the single most important revenue source for European governments. Yet €128 billion (9.5% of the total tax liability) went uncollected due to non-compliance, fraud, insolvencies, and administrative errors.

The good news: the gap decreased from 11.1% in 2019 to 9.5% in 2023 (a drop of 1.6 percentage points). But that still represents €128 billion annually that could fund schools, hospitals, and infrastructure — and governments are no longer willing to accept it.
Country-by-Country Breakdown
The VAT compliance gap varies enormously across Member States. Here are the key figures from the EC's 2025 report:
The standout performer is Austria, which slashed its gap from 6.8% to an EU-best 1.0%. Germany has the largest absolute gap (€31.3 billion) despite a moderate rate — simply due to its economic size. Italy's 4.3pp improvement is widely attributed to its mandatory SDI e-invoicing since 2019.
E-Invoicing & VAT Recovery
The correlation between mandatory Continuous Transaction Controls (CTC) and VAT gap reduction is becoming undeniable:
Italy (SDI since 2019)
Gap dropped from 19.3% to 15.0%. €141.2B collected in 2023, up from €115B pre-mandate.
Hungary (RTIR since 2018)
Real-time invoice reporting reduced the gap from 10.4% to 7.4% — a 29% improvement.
Greece (myDATA since 2020)
VAT gap dropped from 24.0% to 11.4% — the single largest reduction in the EU between 2019 and 2023.
Romania (no CTC yet)
VAT gap remains at 30.0% — the worst in Europe. Now rushing to implement RO e-Factura.
ViDA: The EU's Response
The ViDA (VAT in the Digital Age) directive, adopted by the EU Council, mandates structured e-invoicing for intra-community B2B transactions by July 2030. This means:
Digital Reporting Requirements (DRR)
Real-time reporting of intra-community transactions to a central EU system. Every cross-border B2B invoice must be reported digitally.
EN 16931 as the Standard
The European semantic standard becomes mandatory for cross-border transactions. National formats (XRechnung, Factur-X, FatturaPA) must all interoperate.
Removal of Domestic Derogation Barriers
Member States will no longer need special permission to mandate structured e-invoicing. Every country can (and will) implement CTC systems.
What Businesses Must Do
The wave is unstoppable. Between 2026 and 2030, virtually every EU business will be required to issue and receive structured e-invoices. The question is whether you're prepared.
