How SAF-T compliance requirements are evolving across Europe

Introduction

When the OECD introduced the Standard Audit File for Tax in 2005, it envisioned a universal format for the electronic exchange of accounting data between businesses and tax authorities. Two decades later, that vision is becoming reality across Europe, albeit with significant national variations that create complexity for multinational organisations.

SAF-T compliance is no longer a niche concern affecting only a handful of countries. By 2026, at least ten European nations have active mandates or are in the process of implementing them. For organisations operating across borders, understanding these requirements and preparing their ERP systems accordingly is essential. This article maps the current SAF-T landscape and outlines what organisations should do to stay ahead.

The current SAF-T landscape in Europe

The adoption of SAF-T across Europe has followed a patchwork pattern, with each country defining its own scope, format, submission frequency, and enforcement timeline:

Established mandates. Norway has required SAF-T Financial since 2020 for all VAT-registered businesses. Poland's JPK_VAT has been mandatory since 2018, with monthly or quarterly submissions. Portugal was the first adopter in 2008 and requires monthly SAF-T billing files. Lithuania mandates SAF-T for all VAT-registered businesses, with monthly filing.

Recent implementations. Romania introduced its D406 SAF-T declaration for large taxpayers in 2022 and is extending coverage progressively. Bulgaria launched its SAF-T mandate in January 2026, beginning with large enterprises and rolling out to smaller businesses through 2030.

On-demand requirements. Countries including Austria, France, and Luxembourg require SAF-T submissions upon request from tax authorities rather than on a periodic basis. Whilst this may seem less burdensome, organisations must still be capable of generating compliant files at short notice.

Emerging mandates. Hungary is expected to formalise its SAF-T requirements soon, complementing its existing real-time invoice reporting system. Denmark is developing SAF-T 2.0, with systems required to support it by January 2027.

The impact of the EU's ViDA initiative

The European Commission's VAT in the Digital Age (ViDA) proposal is set to accelerate SAF-T adoption further. ViDA aims to establish a common framework for digital tax reporting across EU member states, promoting convergence between SAF-T and e-invoicing requirements. The implementation timeline stretches from 2025 to 2035, signalling a sustained period of regulatory change.

For organisations, ViDA means that even countries without current SAF-T mandates are likely to introduce digital reporting requirements in the coming years. Preparing now, rather than reacting to each new mandate individually, is the most cost-effective approach to maintaining SAF-T compliance across the European landscape.

Key challenges for multinational organisations

Diverse format requirements. Whilst all SAF-T implementations are based on the OECD's XML schema, each country adds its own elements, validation rules, and structural requirements. A file that satisfies Norwegian requirements will not necessarily comply with Polish or Portuguese specifications.

Varying submission frequencies. Some countries require monthly submissions, others quarterly, and others only upon request. Managing these different cadences across multiple jurisdictions demands robust scheduling and monitoring capabilities.

Data extraction from archived sources. Organisations that have implemented data archiving (a recommended practice for database optimisation) must ensure their tax reporting Europe tools can extract data from both live databases and archive files. Incomplete extractions due to inaccessible archived data can result in non-compliant submissions.

Retention and auditability. SAF-T files themselves must be retained for the period specified by each country's regulations. Organisations need archiving solutions that preserve these files with full integrity and traceability.

Preparing for the evolving landscape

Organisations should take several proactive steps:

Audit current capabilities. Assess whether existing ERP configurations and extraction tools can generate SAF-T files that meet the specific requirements of every country where the organisation operates.

Invest in scalable solutions. Choose standard audit file for tax generation tools that support multiple country formats from a single platform, reducing the need for country-by-country customisation.

Monitor regulatory developments. SAF-T requirements are evolving rapidly. Organisations should establish a process for tracking regulatory changes and updating their systems accordingly.

Ensure archived data accessibility. Verify that data extraction processes can access both online and archived data sources, ensuring complete and accurate SAF-T submissions regardless of where the underlying records are stored.

Conclusion

SAF-T compliance is expanding rapidly across Europe, driven by national mandates and the EU's ViDA initiative. For multinational organisations, the challenge lies in managing diverse, country-specific requirements whilst maintaining a scalable, efficient approach to tax reporting. Those that invest in robust, flexible extraction capabilities and stay ahead of regulatory developments will be best positioned to navigate this evolving landscape with confidence. Organisations managing multi-country obligations often work with specialists such as TJC Group, whose SAF-T solution generates compliant files across European jurisdictions. Organisations managing multi-country SAF-T can talk to TJC Group's tax and audit specialists.

Frequently asked questions

Is SAF-T the same in every country?

No. Whilst all implementations are based on the OECD's XML schema, each country adds its own data elements, validation rules, and structural requirements. Organisations must configure their systems to meet each country's specific specifications.

What happens if an organisation cannot produce a SAF-T file when requested?

Non-compliance can result in administrative fines, increased scrutiny from tax authorities, and potential penalties. The severity varies by country, but the reputational and financial risks are significant in all jurisdictions.

How does SAF-T relate to e-invoicing?

SAF-T and e-invoicing are complementary but distinct. SAF-T provides a standardised file for audit purposes, whilst e-invoicing concerns the real-time exchange of invoice data. The EU's ViDA initiative is promoting convergence between the two, and organisations should prepare for integrated requirements.

Can SAF-T files be generated from archived data?

Yes, provided the organisation's extraction tools can access archive files. This is an important consideration for organisations that have implemented data archiving, as historical records needed for SAF-T submissions may reside in archives rather than the live database.
