Germany’s B2B electronic invoicing law approved

This article was last updated on July 21, 2026, to incorporate the latest BMF/BMJV guidance and strategic enforcement roadmap.

The Growth Opportunities Act

On November 17, 2023, the Growth Opportunities Act (Wachstumschancengesetz), including the compulsory Business-to-Business (B2B) electronic invoicing regulation, was approved by the German Bundestag. The Act underwent several amendments compared to the initially submitted version.

In its session on February 21, 2024, the German Mediation Council revisited the Growth Opportunities Act. The B2B e-invoicing mandate remained largely unchanged, with previous timelines remaining valid. Good news arrived on March 22, 2024, when the Bundesrat approved the Growth Opportunities Act with a clear majority.

This final approval solidifies the B2B electronic invoicing mandate, ensuring its implementation in accordance with the previously established timelines.

Germany’s latest VAT and e-invoicing proposals

Current definition of an electronic invoice

Recent legislative decisions have confirmed the definition of an electronic invoice and the classification of paper invoices under the mandatory e-invoicing rules.

Germany’s electronic invoicing rules for B2B transactions have been in effect since January 1, 2025, though a phase-in period utilising so-called “Übergangsregelungen” (transitional rules) allows for the continued use of paper invoices and “non-compliant” electronic invoices (with recipient consent) until December 31, 2026.

The transitional rules period notwithstanding, an electronic invoice (E-Rechnung) must be issued, transmitted, and received in a structured electronic format that allows automatic processing and correct extraction of VAT-relevant data according to EN 16931 (or another mutually agreed structured format). This includes formats such as XRechnung (the official German standard, originally developed for B2G) and ZUGFeRD (a popular hybrid format, when aligned with EN 16931 from version 2.0 onwards). You can read more about these formats here.

Simple PDF documents or paper invoices will no longer qualify as electronic invoices and will instead be classified as “other invoices” (sonstige Rechnungen).

New mandatory e-invoicing dates and procedures

The following mandatory dates and procedures apply to all Business-to-Business (B2B) invoicing scenarios:

• Since January 1, 2025: All domestic B2B companies must be able to receive structured e-invoices compliant with EN 16931. Buyer consent is no longer required for sending e-invoices, provided the invoice is issued in a structured format.

• Until December 31, 2026: Paper invoices and e-invoices in formats that do not comply with EN16931 are still allowed, but may only be sent with the consent of the recipient.

• From January 1, 2027: B2B e-invoicing issuance obligation for businesses with a previous year's (2026) turnover of EUR 800,000 or more. Businesses are allowed to continue using EDI. 

• From January 1, 2028: B2B e-invoicing issuance obligation for all businesses. EDI is still permitted, provided that the VAT information can be extracted in EN16931.

Strategic readiness checklist: Moving to structured invoicing

As the B2B mandate phases in, businesses should treat compliance as a continuous infrastructure project rather than a one-time event. Regardless of whether your business falls under the 2027 or 2028 issuance requirements, prioritize the following actions to secure your tax compliance:

• Audit your master data: Structured e-invoicing (XRechnung/ZUGFeRD) requires absolute precision for automated processing. Ensure your ERP systems are clean, specifically regarding VAT IDs, customer addresses, and standardized entity codes. Inaccurate data is the most common cause of validation errors and invoice rejections.

• Stress-test your workflows: Do not wait for your mandatory issuance date to start sending structured invoices. Begin issuing them to your most frequent partners early to stress-test your validation, transmission, and receipt workflows while transitional rules still provide a safety net.

• Review archiving (GoBD) strategies: Digital archiving must be future-proofed for long-term storage, machine-readability, and auditability. With regulatory discussions ongoing regarding potential changes to retention periods (see our "Looking forward" section below), businesses should ensure their systems are architected for extended compliance timelines. If you rely on manual PDF storage, start exploring automated, GoBD-compliant DMS solutions now.

• Align with IT and vendors: Confirm that your specific EDI or ERP configuration is capable of EN 16931-compliant extraction. Many legacy systems require specific patches or middleware updates to handle these data requirements; verifying this early prevents bottlenecks when your specific deadline arrives.

The status of EDI

The status of EDI has been clarified: EDI remains permitted for B2B electronic invoicing as long as the chosen format enables the correct and complete extraction of VAT-relevant data in line with EN 16931 (or another mutually agreed structured format). No further legislative vote is required.

Note for EDI users: While EDI remains a permitted transmission method, do not assume your existing setup is compliant by default. The critical requirement is that the system must enable the correct and complete extraction of VAT-relevant data in line with EN 16931. We have seen many businesses with legacy EDI connections that technically transmit data but fail the validation rules required by the new German mandate. Validate your specific EDI message mapping against the EN 16931 standard immediately.

Practical guidance and technical evolution

In March 2026, the German Federal Chamber of Tax Consultants (BStBK) published an updated FAQ on electronic invoicing, providing practical guidance on structured e-invoices compliant with EN 16931, including formats such as XRechnung and ZUGFeRD (version 2.0 and later). The guidance highlights key validation requirements, VAT-relevant data checks, and integration into accounting workflows. It also emphasises archiving that is compliant with the German standard for digital record-keeping and audit (known as GoBD), requiring that structured invoice data remains unchanged, machine-readable, and accessible for audit purposes.

In parallel, KoSIT, the German standards body behind XRechnung, has introduced a roadmap for XRechnung 4.0, which expands the standard beyond its original B2G focus to better support B2B use cases. The update includes new data elements aligned with the Digital Reporting Requirements (DRR) under ViDA, reinforcing Germany’s move towards more automated and potentially real-time VAT reporting.

These technical developments, particularly the expansion of standards like XRechnung 4.0, align with broader government policy signals aiming to link structured invoicing data with enhanced digital audit and analytics capabilities in the near future.

The German Electronic Business Address (GEBA) and Peppol

While the obligation for all B2B companies to receive structured e-invoices compliant with EN 16931 has been active since January 1, 2025, Germany has created an additional infrastructure to significantly simplify the technical handling of sending and receiving: the German Electronic Business Address (GEBA).

• Foundation: GEBA is a standardized electronic identifier for companies and their sub-units within the Peppol network, built upon the national business identification number (Wirtschafts-Identifikationsnummer, or short W-IdNr), which is being issued by the Federal Central Tax Office (BZSt) since late 2024. For companies with a VAT ID, the W-IdNr is identical.

• Structure: A GEBA address can contain up to three components, allowing for precise routing within complex organizations: the Core W-IdNr (mandatory), an optional Distinguishing Feature (for different business locations), and an optional Sub-addressing suffix (for internal departments like Purchasing or Accounting).

• Routing: It allows complex internal company structures to be precisely mapped in the Peppol network, improving the routing of e-invoices to the correct department (e.g., purchasing, accounting).

• Status: The use of GEBA is entirely voluntary and acts as an infrastructure layer to improve document routing and interoperability, not a new bureaucratic hurdle. It coexists with other addressing systems like GLN or Leitweg-ID.

• Technical integration: GEBA is registered for Peppol under the international identification scheme ISO/IEC 6523 Code “0246”. Its official specification was published by KoSIT's XStandards Einkauf (XSE) in December 2025 and was subsequently added to the Peppol identifier scheme code list starting with v9.5 (from Dec 23, 2025).

GEBA is seen by commentators as a foundational building block for potential future developments in German e-reporting, such as a 5-corner model that could eventually integrate tax authorities, positioning Germany for tighter digital VAT controls.

Germany’s e-invoicing history

Germany, like many European Member States, currently has Business-to-Government (B2G) e-invoicing mandates in place. All public bodies must be able to receive electronic invoices, and all public body suppliers must send electronic invoices to their government contractor.

The first inclination of Germany’s intentions to mandate B2B electronic invoicing was on June 23, 2023, when the European Commission gave the country permission to move away from certain parts of the European VAT directive. 

Germany’s plan aligns with the VAT in the Digital Age directive, which is also persuading many European Member States to address their e-invoicing regulation intentions.

Looking forward: The broader digital enforcement roadmap

While current attention is rightly focused on the imminent 2027 and 2028 B2B e-invoicing issuance mandates, recent policy signals from the German government indicate a broader strategic shift toward “digital-first” tax enforcement. These objectives were explicitly detailed in the July 2026 Action Plan published by the Federal Ministry of Finance (BMF) and the Federal Ministry of Justice (BMJV): Aktionsplan: Steuer- und Finanzkriminalität entschlossen bekämpfen.

It is important to note that these initiatives are currently part of a policy roadmap rather than enacted law, but they provide a clear view of Germany’s long-term tax digitalization objectives. The technical foundation for this transition is already being laid through initiatives like XRechnung 4.0, which introduces data elements specifically designed to support these future reporting requirements.

• Electronic VAT reporting (Umsatzsteuer-Meldesystem): The government has signaled intentions to develop an electronic VAT reporting system designed for near-real-time, transaction-level reporting. This suggests that the current e-invoicing transition is just the first step in moving from periodic declarations to a regime of granular, automated VAT data collection.

• Enhanced audit and AI-supported risk detection: The roadmap includes plans for a new data-analysis centre and the deployment of AI-supported risk detection. This will likely utilize the structured data generated by the new e-invoicing infrastructure to scrutinize transaction and invoice data with much greater precision than previously possible.

• Extended retention periods: A significant proposal under consideration is the extension of retention periods for Buchungsbelege (accounting documents) from 10 to 15 years. For businesses and service providers, this signals a need to review current storage architecture, archiving strategies, and compliance messaging to ensure long-term retrieval capabilities.

• Wider digital enforcement: Broader trends, such as the Registrierkassenpflicht (cash register obligation) planned for 2028, underline a government-wide move toward tightening compliance and increasing the intensity of inter-authority cooperation.

For businesses operating in Germany, the message is clear: the environment is shifting toward more digital data, advanced analytics, and significantly lower tolerance for reporting gaps. While these measures are not yet binding, they are critical factors to consider when building your digital compliance strategy for the coming years.
