Along with falling leaves, we have also seen a raft of developments in the world of electronic invoicing. New draft legislation, clarifications and technical updates continue to shape the e-invoicing landscape across Europe and beyond.<\/p>\n\n\n\n
Retarus has once again summarized the most important developments for you \u2013 with a particular focus on countries which are especially relevant for our customers<\/a>\u00a0 and international companies based or operating in Europe.<\/p>\n\n\n\n And if you\u2019d like to take a deeper dive::<\/p>\n\n\n\n Webinar: \u201eE-Invoicing 2026: Neue Regularien und relevante \u00c4nderungen in Europa und Nahost\u201c<\/strong> (in German) The EU\u2019s EN 16931 standard was officially updated by the CEN (European Committee for Standardization) in October 2025. This revised version forms the foundation for the future implementation of ViDA while also expanding the semantic data model for B2B transactions. Key changes include a clear separation between mandatory and optional fields, as well as a standardized method for expanding the platform to meet sector-specific requirements.<\/p>\n\n\n\n Within the scope of their \u201cViDa Implementation Dialogue\u201d, the European Commission also approached representatives of businesses and other organizations directly affected by the package of regulations in late October to consult them on the practical challenges they are facing. Businesses are especially calling for technical specifications to be published well in advance and for harmonized methods of communication between the various member states \u2013 crucial issues for enabling automation and compliance in e-invoicing. On October 15th<\/sup>, 2025, the German Federal Ministry of Finance (BMF) issued an information letter addressing digital invoicing. In future, the authority will distinguish between errors in format, errors in business regulations and errors concerning the content of invoices.<\/p>\n\n\n\n Especially noteworthy:<\/p>\n\n\n\n BMF Information Letter of October 15th<\/sup>, 2025<\/a><\/p>\n\n\n\n The French draft Finance Bill for 2026 (Projet de loi de finances n\u00b0 1906) contains comprehensive amendments to the forthcoming e-invoicing regime. Key changes include: <\/p>\n\n\n\n Draft Finance Bill no. 1906<\/a><\/p>\n\n\n\n In addition, the French IT agency, AIFE, has opened up the test environment for the PFF (Public Invoicing Portal), marking a crucial step in the process to authorize accredited platforms. Beyond this, a new self-assessment questionnaire has been released to support companies in determining their future obligations: This fall, the Polish Ministry of Finance implemented a host of new measures with regard to its national e-invoicing system, KSeF:<\/p>\n\n\n\n Draft JPK_VAT regulation<\/a> In addition, a pre-production API (KSeF 2.0-Demo) has been published, enabling the testing of ERP and accounting systems: Slovakia has brought its draft bill for introducing mandatory e-invoicing and real-time reporting before parliament. The aim is to achieve an EN-16931-compliant format, administrated by certified transmission services, which will serve to guarantee the authenticity, integrity and legibility of the invoices. Slovenia\u2019s national council has passed the proposed law on the interchange of electronic invoices and documents. From January 1st<\/sup>, 2028, all companies in the national trade register will be required to issue structured electronic invoices (XML). The law allows the use of Peppol and direct data interchange in addition to the free miniBlagajna<\/em> solution f\u00fcr SMEs. The deadline for implementing the E-Fatura system in the pharmaceutical sector has been pushed back to December 1st<\/sup>, 2025. For pharmacies and opticians, the deadline remains October 1, 2026. The final date for implementing electronic invoicing has been pushed back to December 31st<\/sup>, 2026. The duty to implement the qualified electronic signature (QES) has been postponed until January 2027; SAF-T accounting will now also be required as of the fiscal year 2027. Europe has been consolidating its e-invoicing landscape with the aim of standardization and automation \u2013 with a clear trend towards ViDA compatibility and Peppol integration.
