Slovenia’s draft proposal to enforce e-invoicing from June 2026

A step towards digital transformation.

On 19 July 2024, Slovenia took a new step in digitalizing its financial reporting by publishing a draft proposal for the Act on the Exchange of Electronic Invoices and Other Electronic Documents. This legislative move, aiming for implementation by 1 June 2026, mandates that e-invoices be reported to the Slovenian tax authority (FURS) within 8 days of issuance and receipt.

The requirement applies to both domestic and cross-border B2B transactions, though B2C invoices remain outside the scope of this draft legislation.

Key Aspects of the Draft Legislation

E-Invoicing Formats

The proposal specifies three acceptable formats for the exchange of e-invoices:

  • The e-SLOG national standard
  • The EN 16931 EU standard
  • Other internationally recognized formats agreed upon by both parties involved in the transaction

Reporting Requirements

E-invoices must be reported to FURS within 8 days of issuance and receipt. This applies whether the transactions are domestic or cross-border B2B.

Legislative Process

The draft proposal is currently under review and awaiting approval by the National Assembly.

Detailed Insights

The proposed legislation aligns with the European Directive 2014/55/EU, which standardizes electronic invoicing across the EU for public procurement. By adopting the e-SLOG national standard alongside the EN 16931 EU standard, Slovenia ensures compatibility with broader EU regulations and facilitates smoother cross-border transactions.

Implementation and Compliance

  • For Businesses: All B2B transactions must comply with the new e-invoicing formats and reporting timelines.
  • Exemptions: The mandate does not apply to B2C invoices.
  • Technical Standards: Businesses are encouraged to use the e-SLOG standard for consistency and efficiency. The flexibility to use internationally recognized formats ensures that businesses can maintain their existing systems if they meet the necessary criteria.

Industry Impact

This move towards mandatory e-invoicing and e-reporting aims to streamline financial processes, reduce administrative burdens, and enhance tax compliance.

It is expected to bring numerous benefits, including:

  • Improved efficiency in invoice processing
  • Reduced errors and discrepancies in financial reporting
  • Enhanced ability to track and manage transactions

Key Takeaways

  • Mandatory E-Invoicing: Effective 1 June 2026 for all B2B transactions.
  • Reporting Deadline: E-invoices must be reported within 8 days of issuance and receipt.
  • Standardized Formats: Adoption of e-SLOG, EN 16931, or mutually agreed international formats.
  • Legislative Status: Awaiting review and approval by the National Assembly.

For businesses operating in Slovenia or engaging in cross-border B2B transactions with Slovenian entities, it is crucial to begin preparations to meet these new requirements. The draft legislation provides a framework that, once approved, will necessitate significant adjustments in invoicing and reporting practices.
