Peppol expands ViDA pilot with integrated tax reporting tests
New pilot capabilities show how e-invoicing and VAT reporting may converge under ViDA
The OpenPeppol ViDA Pilot has entered a new phase. Updated test environments now support both e-invoicing and tax reporting scenarios, giving service providers and stakeholders a more practical view of how Europe’s future Digital Reporting Requirements (DRR) could operate in practice.
The development matters because it moves ViDA discussions beyond policy and into operational testing. Rather than focusing only on invoice exchange, the pilot now explores how invoice data and VAT reporting obligations may become increasingly connected within a single cross-border framework.
The OpenPeppol ViDA Pilot was launched as a multi-stakeholder initiative to assess how the Peppol network could support the European Commission’s ViDA objectives. As outlined in our earlier article on Europe’s expectations for ViDA e-invoicing, the direction of travel within Europe is becoming clearer: more standardisation, more interoperability and faster access to transaction data for tax authorities.
New test suites combine invoicing and reporting
OpenPeppol has now released two expanded pilot test suites:
- ViDA Billing 3.0 and Tax Reporting
- ViDA Self-Billing 3.0 and Tax Reporting
The updated environments allow service providers to exchange BIS Billing 3.0 compliant documents while also submitting ViDA Tax Data Documents (TDD) through a dedicated reporting flow.
This effectively introduces testing for a broader five-corner exchange model, where invoice data is not only exchanged between trading partners but can also be routed towards tax authorities through designated reporting channels.
The pilot additionally supports simulation of cross-border reporting scenarios, including routing logic, timing validation and data standardisation between market participants and authorities.
Why this matters beyond technical testing
At first sight, the update may appear highly technical. In practice, however, it reflects a broader shift taking place across Europe.
E-invoicing is increasingly moving beyond document digitisation alone. Governments are gradually linking invoice exchange with tax reporting, VAT controls and transaction visibility.
Several European countries are already implementing or preparing continuous transaction control models, national reporting platforms or near real-time reporting obligations. The ViDA initiative attempts to create greater alignment between these fragmented approaches.
The OpenPeppol pilot therefore provides an early indication of how interoperability between invoice exchange and tax reporting could evolve at European level.
This also connects with broader Peppol developments discussed in our earlier article on the new global Peppol e-invoicing standard for 2026. As Peppol specifications continue to evolve, the network is increasingly positioned not only as a document exchange framework, but potentially as part of a wider compliance infrastructure.
Peppol BIS Billing 3.0 remains central
The pilot continues to build on Peppol BIS Billing 3.0, which remains the core invoicing specification used across many European implementations.
Recent updates to the framework, including those covered in our article on the Peppol BIS Billing 3.0 v3.0.20 update, already demonstrated how rapidly the ecosystem is adapting to changing regulatory and operational requirements.
The latest ViDA pilot extension reinforces the importance of maintaining alignment between ERP systems, invoice formats, reporting requirements and service provider capabilities.
What companies should take away from this
The OpenPeppol ViDA Pilot does not yet define final European architecture or mandatory implementation rules. However, it does provide a strong indication of the direction many compliance models are taking.
For finance and digital transformation teams, the key message is that e-invoicing and tax reporting can no longer be treated as separate topics.
Future compliance models will increasingly depend on:
- Structured invoice data
- Cross-border interoperability
- Near real-time reporting capabilities
- Standardised exchange frameworks
- Scalable ERP integration
This becomes especially relevant for multinational organisations operating across multiple regulatory models and local mandates. As shown in our overview of European e-invoicing country developments, implementation approaches continue to differ significantly between member states.
At the same time, European initiatives such as ViDA are gradually pushing towards more harmonisation in data structures, reporting logic and interoperability expectations.
Changes companies need to implement
- Review whether current e-invoicing architectures can support future tax reporting requirements
- Assess ERP readiness for structured reporting data flows
- Monitor how ViDA reporting obligations evolve at EU level
- Evaluate the role of Peppol connectivity within long-term compliance strategies
- Prepare for increasing convergence between invoice exchange and VAT reporting processes
