Germany

This article was updated on 19 October 2026 because of the BMF Schreiben of 15 October 2026 on mandatory electronic invoicing. The update incorporates new guidance on advance and final invoices, structured invoice particulars, construction invoices, discounts, gross-price calculations, corrections, validation errors, public-sector invoicing and penalties. It also explains the transitional concessions extending to 2027 and 2030. The Schreiben supplements the BMF circulars of 15 October 2024 and 15 October 2025; it does not establish a new domestic e-reporting obligation. 

Germany has overhauled its value-added tax framework by extending mandatory electronic invoicing - building upon Business-to-Government (B2G) e-invoicing, which has been in place for several years - to domestic Business-to-Business (B2B) transactions. Enacted under the Growth Opportunities Act (Wachstumschancengesetz), the reform legally redefines electronic invoices, abandoning plain PDFs in favour of structured semantic formats that comply with European standard EN 16931.

Since 1 January 2025, domestic businesses have had to be able to receive qualifying structured B2B e-invoices. For covered supplies made in 2027, issuers whose 2026 turnover exceeded €800,000 generally must issue e-invoices, subject to the separate EDI transition. The general issuance obligation applies from 1 January 2028, while statutory exemptions, including those for small-business scheme issuers, remain in force.

Germany does not currently require domestic B2B invoices to pass through a government clearance or real-time transaction-reporting platform. A future national electronic reporting system is under consideration, but its architecture and start date have not been enacted. Separate EU ViDA digital reporting requirements for relevant intra-EU transactions apply from 1 July 2030.

Introduction & digital tax strategy

Germany is introducing mandatory structured electronic invoicing for covered domestic B2B transactions in phases from 2025 to 2028. Under § 14 UStG, an e-invoice must use a qualifying structured format, subject to statutory exclusions and transitional arrangements.

The primary driver behind this digital shift is twofold: closing the persistent national VAT-gap and modernising business-to-business processes across the continent's largest economy. Reducing VAT fraud and improving the reliability of transaction data are important policy objectives. Structured invoices also make it easier to automate invoice handling and accounting checks. By transitioning transactions into structured digital records, the German tax administration (Finanzverwaltung) establishes the structural baseline necessary to verify tax deductions automatically.

Germany's strategy diverges from the centralised clearance models pioneered in Latin America and southern Europe. Instead of requiring companies to route every invoice through a government validation portal before dispatch, the German legislature has prioritised a decentralised model. Businesses exchange structured documents directly or through private networks, preserving operational speed while establishing standard data syntax.

This B2B transformation does not start from scratch; it builds upon years of mandatory B2G e-invoicing. The public sector rollout introduced distinct German specifics, such as the creation of dedicated invoice submission portals (originally split between the ZRE and OZG-RE, now consolidated into the OZG-RE), the introduction of the mandatory Leitweg-ID for routing within public administration, and the establishment of the national XRechnung CIUS alongside accepted ZUGFeRD profiles. While B2G introduced these rigorous public-sector routing and formatting requirements (including managing Leitweg-IDs that are not stored in a single official directory), the B2B mandate broadens structured invoicing across the entire commercial economy.

Germany does not prescribe a single transmission channel for domestic B2B e-invoices. Businesses can use email or agreed electronic exchange channels, including Peppol, provided the invoice satisfies the statutory format and content requirements. Alternative interoperable formats are also permitted under the conditions of § 14(1) UStG. This format-driven, channel-agnostic approach, combined with the phased rollout beginning with mandatory reception in January 2025 followed by progressive issuing obligations, allows companies flexibility in how they upgrade their existing billing infrastructure.

This regulatory framework acts as the indispensable first phase of a broader two-tier project. Structured electronic invoicing may support a future German electronic transaction-reporting system (elektronisches Meldesystem). The government has not yet enacted its final domestic reporting architecture, transmission requirements or implementation date. Through this staged implementation, Germany balances immediate administrative feasibility for small and medium-sized enterprises with long-term digital tax oversight.

Historical evolution & EU/global context

Germany's digital compliance journey began in the public procurement sector before reaching private-sector commerce. Understanding how these earlier initiatives unfolded illustrates why the current B2B mandate is structured around European norms rather than proprietary domestic interfaces.

How did Germany introduce B2G e-invoicing?

The origin of German electronic invoicing stems from European Union Directive 2014/55/EU (the so-called European legislation on eInvoicing), which mandated that public contracting authorities across all EU member states accept electronic invoices compliant with a common European standard. Germany transposed this directive through the E-Government Act (E-Government-Gesetz) and the Federal E-Invoicing Ordinance (E-Rechnungsverordnung).

Because Germany operates as a federal republic with 16 autonomous states (Bundesländer), the public sector rollout became structurally fragmented. At the federal level, mandatory electronic invoicing for suppliers to the federal administration (Bund) took effect on 27 November 2020, initially utilising two federal gateways: the Zentrale Rechnungseingangsplattform des Bundes (ZRE) and the Onlinezugangsgesetz-konforme Rechnungseingangsplattform (OZG-RE), which have since been consolidated into a single unified platform under the OZG-RE. Concurrently, the states developed their own distinct procurement portals and varying submission thresholds, with several states adopting Peppol infrastructure while others retained web upload portals.

To bridge this operational divergence, the Coordination Agency for IT Standards (Koordinierungsstelle für IT-Standards - KoSIT) established XRechnung. This purely structured XML format served as the official German Core Invoice Usage Specification (CIUS) under European standard EN 16931, proving that automated public sector billing was functionally viable at scale.

How did mandatory domestic B2B e-invoicing become law?

While public procurement demonstrated the strength of structured data, private enterprise transactions remained heavily reliant on unstructured PDF files sent by email. To modernise this private sector exchange, the German Federal Ministry of Finance requested a formal derogation from Articles 218 and 232 of the EU VAT Directive (Directive 2006/112/EC) in November 2022.

The Council of the European Union authorised Germany's derogation through Council Implementing Decision (EU) 2023/1551, adopted on 25 July 2023, permitting specified departures from Articles 218 and 232 of the VAT Directive:

• It permitted Germany to eliminate the long-standing legal requirement that the invoice recipient must consent to receiving an electronic invoice.

• It authorised Germany to require structured electronic invoices for covered domestic B2B transactions, subject to the subsequent national implementing legislation and transitional rules.

Armed with this EU authorisation, the German legislature drafted the Growth Opportunities Act (Wachstumschancengesetz). Following parliamentary debate between the Bundestag and the Bundesrat, the final compromise legislation cleared the Bundesrat on 22 March 2024 and was promulgated in the Federal Law Gazette (Bundesgesetzblatt) on 27 March 2024.

How does Germany's mandate relate to EU ViDA?

The EU has enacted the VAT in the Digital Age (ViDA) package, including Directive (EU) 2025/516. Its structured invoicing and digital reporting requirements for relevant intra-EU transactions apply from 1 July 2030. These EU obligations are distinct from Germany's existing domestic B2B invoice-exchange mandate.

Germany's use of EN 16931 provides a common semantic basis for invoice data, but businesses will still need to assess additional cross-border reporting fields, systems and processes required under ViDA.

Complete compliance timeline

While the primary focus of the current German e-invoicing framework is the B2B mandate, the legal foundation began with public procurement (B2G), where public authorities were gradually mandated to accept structured e-invoices from contractors.

The German B2B mandate is structured around a phased implementation schedule spanning 2025 to 2028, ensuring that businesses have sufficient operational leeway to upgrade systems.

Legal framework

The legal architecture underpinning Germany's electronic invoicing regime is codified directly within primary tax legislation and administrative law:

1. Which laws govern federal B2G e-invoicing?

Governing federal public-sector procurement (B2G), the E-Government Act (E-Government-Gesetz, EGovG) and the Federal E-Invoicing Ordinance (E-Rechnungsverordnung, ERechV), enacted pursuant to EU Directive 2014/55/EU, mandate that suppliers to federal contracting authorities must issue electronic invoices and must, in principle, use the XRechnung standard for electronic invoicing. Alternatively, any other data exchange standard may be used provided it fully complies with the European standard for electronic invoicing (EN 16931). Specific exemptions to the e-invoicing obligation apply, such as for direct orders under €1,000.

These federal rules operate in parallel with the UStG B2B rules. Furthermore, because procurement rules can vary at the state and local levels, B2G requirements may also arise under Länder- (state) and municipality-level implementing rules, which can differ from the federal ERechV framework and involve their own portals and procedures.

2. Which Act introduced mandatory B2B e-invoicing?

Adopted by the Bundestag on 17 November 2023 and passed by the Bundesrat on 22 March 2024, this omnibus economic bill serves as the legislative vehicle that introduced Germany’s mandatory domestic B2B e-invoicing. The Act was published on 27 March 2024 in the Federal Law Gazette, BGBl. 2024 I No. 108. It amended the invoicing provisions of the Umsatzsteuergesetz (UStG), with the new framework applying to supplies made from 1 January 2025, subject to transitional rules.

3. What do §§ 14 and 27(38) UStG require?

The Wachstumschancengesetz directly amended Section 14 and Section 27 of the German VAT Act (Umsatzsteuergesetz, UStG):

• Section 14(1), sixth sentence, UStG (definition of an electronic invoice): The law establishes a statutory distinction between an “electronic invoice” (elektronische Rechnung) and an “other invoice” (sonstige Rechnung). Under § 14(1) UStG, an e-invoice must be issued, transmitted and received in a structured electronic format that enables electronic processing. It must comply with EN 16931 and the applicable syntax requirements, or use a mutually agreed format that allows correct and complete extraction of the information required under the UStG into a compliant or interoperable format. All paper invoices, image files, and ordinary PDFs are classified legally as “other invoices” rather than e‑invoices for VAT purposes.

• Section 14(2) UStG (mandatory domestic B2B issuance requirement): Sets out the statutory obligation for taxable persons established in Germany to issue a structured electronic invoice for supplies carried out to other domestic taxable persons for their businesses.

• Section 27(38) UStG (transitional issuance provisions): Establishes the exact legal parameters for the phased implementation of the issuing obligation: businesses with 2026 total turnover exceeding €800,000 must issue e‑invoices from 1 January 2027, with the general domestic B2B issuing obligation applying from 1 January 2028. It permits paper invoices and, with recipient consent, other electronic invoices for qualifying supplies through 2026 and for issuers with preceding-year turnover not exceeding €800,000 through 2027. A separate rule permits qualifying non-compliant EDI transmissions through 2027, subject to recipient consent.

4. BMF guidance and GoBD

The Federal Ministry of Finance (BMF) provides the key administrative interpretation through circulars (BMF-Schreiben), regularly updated FAQs, and the German standard for digital record-keeping and audit (Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form sowie zum Datenzugriff, or short, GoBD).

• The BMF published its initial guidance on 15 October 2024 (BStBl I 2024, p. 1320), amended and supplemented it on 15 October 2025 (BStBl I 2025, p. 1806), and issued further supplementary guidance on 15 October 2026. All three documents remain relevant to the administrative interpretation.

• The BMF’s regularly updated e‑invoice FAQ, which clarifies scope, receipt/issue obligations, formats, transmission channels, exemptions, and the relationship between UStG and ERechV.

• The applicable GoBD requirements, including the amendments relevant to electronic record-keeping and tax-audit access (the German standard for digital record-keeping and audit), which govern orderly electronic recordkeeping, retention, auditability, and data access. These are especially relevant to retaining the authoritative structured invoice data, not merely a human‑readable rendering.

• The 2026 guidance adds specific rules on advance and final invoices, business-customer identification, service descriptions, construction invoices, discounts, gross-price calculations, corrections and validation errors. It also clarifies public-sector overlaps and penalties. For invoices issued by 31 December 2026, the BMF will not object, including for input VAT purposes, if they satisfy the 2024 and 2025 guidance but not additional requirements introduced in 2026.

5. What is the role of EN 16931 and Directive 2014/55/EU?

EN 16931 is the European semantic data model defined under European Directive 2014/55/EU and maintained by the European Committee for Standardisation (CEN). It is the central technical legal benchmark under Section 14(1) sentence 6 UStG and the foundation for accepted structured formats such as XRechnung, ZUGFeRD/Factur‑X (in qualifying profiles), and Peppol BIS Billing 3.0.

Regulatory authorities, operational infrastructure, and other key actors

Several public authorities and standardisation bodies govern, administer, and maintain the German e-invoicing ecosystem:

What is the BMF's role in German e-invoicing?

The BMF (Bundesministerium der Finanzen, or Federal Ministry of Finance) holds supreme administrative responsibility for the federal tax code. It designs VAT policy, drafts national legislation, and issues binding administrative decrees that guide how the 16 federal state tax offices (Länder) apply the German VAT Act. The BMF also co-led the consolidation of federal invoice-receipt platforms onto OZG‑RE.

Which state tax authorities enforce VAT compliance?

While federal ministries set VAT law, tax collection and audit enforcement in Germany are principally carried out at the state level. Local tax offices (Finanzämter) assess compliance in audits, including verifying whether invoices meet statutory VAT deductibility criteria.

What VAT functions does the BZSt perform?

The BZSt (Bundeszentralamt für Steuern, or Federal Central Tax Office), a federal authority within the BMF’s portfolio, oversees specific central federal tax-administration functions, including cross-border information exchange and VAT-related functions, and assigns the national Business Identification Number (Wirtschafts-Identifikationsnummer - W-IdNr).

The BZSt already performs specified federal VAT-administration and information-exchange functions. No legally confirmed operator has been identified for Germany's proposed domestic transaction-reporting system.

What does KoSIT maintain for German e-invoicing?

Operating on behalf of the IT Planning Council (IT-Planungsrat), KoSIT (Koordinierungsstelle für IT-Standards, the Coordination Office for IT Standards) maintains the semantic specifications of XRechnung. KoSIT maintains the XRechnung specification and its associated validation artefacts, including business-rule checks. Implementers must use the applicable specification and validator version for their invoice profile.

KoSIT also operates the German Peppol Authority. In that role, it governs Germany’s participation in the Peppol network, including the onboarding and supervision of German Peppol Access Points and Service Metadata Publishers, and implementation of the relevant national Peppol specifications and policy requirements. KoSIT also maintains the GEBA (German Electronic Business Address) specification, a W‑IdNr.-based addressing scheme designed for use as a Peppol participant identifier. Individual participant registrations and endpoint records are managed by Peppol service providers/SMPs, while the underlying W‑IdNr. is allocated by the BZSt.

What is FeRD's role in the ZUGFeRD standard?

FeRD (Forum elektronische Rechnung Deutschland, or Forum for Electronic Invoicing Germany) is the German industry forum that develops and maintains the ZUGFeRD specification - the German hybrid PDF/A‑3 plus structured XML invoice format - jointly aligned with the French Factur‑X format through cooperation with France’s FNFE‑MPE. It publishes the ZUGFeRD specifications, schemas, profiles, and supporting implementation material.

Which federal B2G invoice submission portal is active?

OZG‑konforme Rechnungseingangsplattform (OZG‑RE) is the active central federal invoice-receipt platform. Following the federal consolidation on 19 September 2025, it became the single platform for receipt of electronic invoices across the federal administration; ZRE was decommissioned for invoice receipt and shut down at the end of 2025.

The earlier ZRE had been operated by ITZBund, while OZG‑RE was operated by the Procurement Office of the Federal Ministry of the Interior (Beschaffungsamt des BMI, BeschA). The consolidation was jointly designated by the BMI and BMF.

Who assigns the Leitweg-ID for B2G invoices?

Leitweg‑IDs, routing IDs used specifically in German B2G e-invoicing, are assigned decentrally by federal and state issuing bodies. Suppliers normally obtain the identifier directly from the contracting authority or invoice recipient. There is no single nationwide operational issuer or comprehensive public directory of all Leitweg‑IDs.

KoSIT maintains the Leitweg‑ID specification as part of the XRechnung standard, including its structure and validation rules, but does not allocate individual Leitweg‑IDs.

The Leitweg‑ID is normally populated in BT‑10 (Buyer reference) in an XRechnung. It enables routing within public-sector invoice-receipt systems and is relevant to B2G invoicing; it is not a general requirement for domestic B2B e‑invoicing.

Scope of the mandate

The German e-invoicing framework applies across both public procurement (B2G) and commercial transactions (B2B), governed by distinct statutory baselines and timelines.

Which public-sector transactions require e-invoices?

Public-sector invoicing may be governed by both VAT invoicing law and separate federal, state or municipal procurement rules. Under the BMF's 2026 guidance, paragraphs 24–25, VAT-based mandatory e-invoicing applies to a public authority when it acts as a taxable business. Applicable procurement rules may require e-invoices even when the authority acts in a non-business capacity. If both regimes apply, the invoice must satisfy both, including the stricter applicable requirement.

Which B2G suppliers are covered?

Any commercial enterprise, small business, or contractor supplying federal, state (Länder), or municipal public administration bodies.

Which B2G transactions are covered?

All public-sector contracts exceeding statutory thresholds (such as federal direct orders above €1,000), requiring structured e-invoices compliant with EN 16931 (primarily XRechnung or accepted ZUGFeRD profiles).

What exemptions apply to B2G invoicing?

Specific procurement exceptions under the Federal E-Invoicing Ordinance (ERechV) and corresponding state-level ordinances, including classified contracts or low-value direct orders.

Which domestic B2B transactions require e-invoicing?

Which B2B businesses are covered?

The domestic B2B mandate generally applies where the supplier and business customer meet the domestic establishment conditions under § 14(2) UStG. A foreign supplier's German VAT registration alone does not automatically establish it in Germany. A participating German fixed establishment may affect the analysis.Under Section 14(2) UStG, an enterprise is established in Germany if it has:

• Its registered corporate headquarters (Sitz) in Germany; or

• Its central management (Geschäftsleitung) located in Germany; or

• A domestic permanent establishment (Betriebsstätte) that participates directly in the underlying transaction.

If an enterprise possesses only a purely formal VAT registration in Germany without a permanent commercial establishment, it is considered non-established and remains outside the mandatory domestic issuance rules.

Which B2B supplies fall within the mandate?

Mandatory e-invoicing generally covers qualifying domestic B2B supplies, whether taxable or exempt, unless the particular supply or issuer falls within a statutory exclusion. Notably, supplies exempt under § 4 Nos. 8–29 UStG are excluded from the corresponding mandatory issuance requirement.

• Both the supplier and the customer are established in Germany; and

• The transaction has its legal place of supply within Germany; and

• The supply is not subject to specific statutory exclusions.

Which transactions are excluded from mandatory e-invoicing?

The mandate contains statutory exclusions and transitional concessions. Separately, the BMF Schreiben of 15 October 2026, paragraphs 26–27, provides non-objection relief for notices assessing public-law fees, contributions or reimbursement charges that also constitute VAT invoices. Such notices may be issued as 'other invoices' until 30 June 2030. If a separate VAT invoice is issued, businesses must avoid duplicate VAT disclosure that could trigger liability under § 14c UStG.

• Business-to-Consumer (B2C) sales: Transactions involving non-taxable private individuals do not require structured e-invoices.

• Cross-border supplies: Both intra-Community supplies and export transactions to third countries remain outside the domestic mandate. These continue to follow existing invoicing arrangements until the EU ViDA regulations take effect in 2030.

• Small-value invoices (Kleinbetragsrechnungen): Invoices whose total gross amount does not exceed €250 (regulated under Section 33 of the VAT Implementation Ordinance - Umsatzsteuer-Durchführungsverordnung / UStDV) are exempt from mandatory structured e-invoicing. They may continue to be issued as paper or standard PDF documents.

• Passenger transport tickets: Travel tickets issued in accordance with Section 34 UStDV may continue to be provided in conventional paper or PDF formats.

• Specific VAT-exempt services: Supplies that are tax-exempt under Section 4 Nos. 8 to 29 UStG (such as certain financial, banking, insurance, and medical services) are generally exempt from the statutory obligation to issue invoices under Section 14(2) UStG. These supplies do not trigger mandatory structured e-invoicing under the general B2B issuance rule, even where a supplier voluntarily issues an invoice. Other applicable invoicing requirements must still be observed.

Must Kleinunternehmer issue and receive e-invoices?

Businesses applying the small-business regime under § 19 UStG must be technically capable of receiving structured e‑invoices from 1 January 2025. However, invoices issued by such Kleinunternehmer are exempt from the domestic B2B obligation to issue structured e‑invoices. Under § 34a UStDV, qualifying Kleinunternehmer may continue issuing paper invoices or, with the recipient's agreement, other electronic invoices such as standard PDFs after 1 January 2028.Their invoices will continue to display no stated VAT amount pursuant to Section 19 UStG.

Note that if a business ceases to qualify for the § 19 small-business regime, it would then become subject to the normal issuing rules for in-scope domestic B2B supplies.

Further note that the issuer exemption in § 34a UStDV applies to the domestic B2B VAT e‑invoicing obligation. It does not, by itself, exempt a Kleinunternehmer from separate B2G e‑invoicing requirements imposed under federal, state or municipal procurement rules.

Germany's e-invoicing requirements

Germany’s e‑invoicing landscape combines two related but separate regimes:

• Domestic B2B invoicing: VAT-law rules in the German VAT Act (Umsatzsteuergesetz, UStG), supported by BMF guidance.

• B2G invoicing: Federal and Länder public-procurement rules. At the federal level, the key framework is the E‑Government Act and the Federal E‑Invoicing Ordinance (ERechV). Requirements can differ for Länder and municipal authorities.

The transition affects advance, interim and final invoices as well as ordinary sales invoices. Under the BMF Schreiben of 15 October 2026, paragraphs 2–4, an advance or interim invoice lawfully issued before the supplier's mandatory e-invoice phase need not be reissued solely because payment or performance takes place later. Until 30 June 2030, certain final invoices may deduct advance payments using BT-113 with details in BT-22, or through a qualifying embedded attachment expressly referenced in the structured invoice.

What qualifies as an e-invoice under § 14 UStG?

For B2G transactions, federal authorities principally accept XRechnung and qualifying EN 16931-compliant alternatives; the public authority’s applicable federal, Land, or municipal rules and submission channel must be followed.

On the other hand, for the domestic B2B regime, under amended Section 14(1) UStG, an electronic invoice is no longer defined by its transmission medium (such as an email attachment). The legal definition depends on the invoice's qualifying structured format and electronic processing capability. To constitute a proper VAT invoice, its structured data must also include sufficient information to identify the supplied goods or services and assess their tax treatment, including their nature, extent and, where relevant, place. Supplementary details such as timesheets may appear in an embedded attachment.

A qualifying e-invoice must use a structured, electronically processable format and contain the statutory invoice particulars. Where bonuses, cash discounts or rebates have been agreed in advance but their amount is not yet known, the invoice must clearly refer to the agreement. Under the BMF's 2026 non-objection guidance, a general reference to a written agreement is sufficient if the underlying records can promptly be produced and readily checked. A later change to the agreement does not, by itself, require an invoice correction.

1. Complies with the European standard EN 16931 and its permitted syntaxes; or

2. is an alternative format agreed between the parties that is completely interoperable with EN 16931, enabling the automatic and electronic extraction of all statutory VAT information required under the German VAT Act.

Any document not meeting these requirements is legally categorised as an “other invoice” (sonstige Rechnung). A standard PDF, a scanned document, a Word file, or a paper printout all constitute “other invoices”, rather than e‑invoices under the B2B VAT definition.

After the applicable transition, an 'other invoice' generally does not fulfil the structured e-invoice issuance obligation for an in-scope domestic B2B supply. However, its VAT treatment, the recipient's deduction position and any sanctions must be assessed separately. The BMF Schreiben of 15 October 2026 confirms that issuing an 'other invoice' instead does not itself constitute the offence in § 26a(2) No. 1 UStG.

Statutory exemptions continue to apply. Where a structured e-invoice is mandatory, a correction must generally also be made through an e-invoice using an appropriate correction type. The original invoice and correction must together establish the final particulars clearly. Under the amended UStAE, an agreed buyer-issued Gutschrift may also correct or supplement an invoice if it refers specifically and unambiguously to the original.

How may German businesses send and receive e-invoices?

For federal B2G transactions, invoices must be submitted through the channels accepted by the federal invoice-receipt platform, currently OZG‑RE. Available methods include web submission, manual upload, Peppol and email, but the applicable recipient requirements, including - crucially - the Leitweg-ID, must be observed. Other public authorities may use different Länder- or local portals and rules.

For B2B invoice exchange, the BMF guidance of 15 October 2024 and 15 October 2025 continues to recognise flexible transmission channels. The supplementary guidance of 15 October 2026 addresses additional invoice-content and compliance questions without mandating a central transmission platform:

• Email: The transmission of a structured XML or hybrid file via standard email satisfies the legal requirement. A normal email inbox can provide the technical ability to receive structured e-invoices required since 1 January 2025. A dedicated mailbox is not mandated, although businesses still need a suitable process for preserving, reading and handling the received invoice data.A business cannot refuse an e-invoice simply because it arrived by standard email.

• Platforms & portals: By agreement, businesses may use web portals, cloud storage download links, shared storage, APIs, EDI, or comparable channels to exchange documents.

• Peppol network: While Peppol is not legally mandated for private-sector B2B transactions, it is a permitted interoperability delivery network.

Is buyer consent required for German e-invoices?

While buyer consent was eliminated in the public sector (B2G) years ago through mandatory reception rules introduced between 2018 and 2020, the Growth Opportunities Act now extends this principle to commercial trade.

For domestic B2B invoices, prior to 2025, Section 14(1) UStG required the invoice recipient to agree to receiving an electronic invoice. Under the amended law, buyer consent is abolished for all compliant structured e-invoices.

An enterprise established in Germany must accept a structured e-invoice provided by a supplier. If a buyer refuses to accept a compliant structured file, the supplier is legally deemed to have fulfilled its invoicing obligation, leaving the buyer unable to demand a paper substitute.

Consent remains relevant for an “other” electronic invoice, such as a standard PDF, during periods or situations in which use of an “other invoice” remains permitted.

How long must German e-invoices be archived?

Electronic invoices must be retained under the relevant GoBD and § 14b UStG requirements. Electronic storage elsewhere in the EU may be permitted where the statutory remote-access conditions are met, with required notification to the tax office. Storage outside the EU is subject to additional conditions under the Fiscal Code.(Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form sowie zum Datenzugriff - GoBD):

• Structured data retention: Electronic invoices must be retained electronically so that their tax-relevant structured data remains available, unaltered and readable. A paper printout or visual rendering alone is insufficient. Archiving procedures should preserve the received structured invoice and relevant attachments in accordance with § 14b UStG and the applicable GoBD.

• Integrity and retention: Invoices generally require eight years' retention, calculated from the end of the calendar year of issue, under § 14b UStG. Systems must preserve authenticity, integrity, legibility and audit access. Other records may be subject to different or longer retention periods, and transitional exceptions must be considered.

• Machine readability and audit access: Stored structured invoices must remain available for examination and, where required, electronic tax-audit access. Appropriate indexing, retrieval and export functions support compliance with the applicable GoBD requirements.

• Hybrid format archiving (ZUGFeRD): For hybrid invoices, the original hybrid PDF/A‑3 file with its embedded XML must be archived in the form received as a single unit. For qualifying hybrid e-invoices, the structured invoice data is decisive for VAT purposes where it differs from the visual representation. Businesses should retain the complete hybrid document and any tax-relevant embedded attachments in accordance with the applicable retention requirements.

Germany's e-reporting roadmap & ViDA alignment

A frequent source of market confusion is the distinction between Germany's active domestic B2B e-invoicing mandate and a future electronic transaction reporting system (elektronisches Meldesystem). Germany has introduced structured e‑invoicing in advance of, but separately from, any domestic real-time digital reporting regime.

What VAT reporting is currently mandatory in Germany?

Germany currently operates no real-time invoice clearance or domestic transaction reporting platform for B2B invoices. Suppliers do not need to submit domestic B2B invoices to the tax authorities for clearance prior to sending them to customers, nor are they required to upload domestic invoice extracts to a central tax portal at the time of issuance.

Germany generally applies a 19% standard VAT rate and a 7% reduced rate for qualifying supplies. A 0% rate applies to certain qualifying photovoltaic installations and related transactions. Rates and exemptions are governed by § 12 UStG. VAT returns remain separate from the domestic e-invoice exchange obligation:Advance VAT returns (Umsatzsteuer-Voranmeldungen), submitted monthly or quarterly via the ELSTER portal.

• Advance VAT returns (Umsatzsteuer-Voranmeldungen) are normally filed electronically for monthly or quarterly periods and are generally due by the 10th day after the reporting period, subject to extensions and taxpayer-specific rules under § 18 UStG. These returns are not real-time invoice-level reporting.

• Annual VAT returns (Umsatzsteuer-Jahreserklärungen).

• Recapitulative statements (Zusammenfassende Meldungen, ZM) for relevant intra-Community transactions are filed electronically with the BZSt, generally by the 25th day after the relevant reporting period. The reporting period may be monthly or quarterly depending on the transaction category and applicable conditions under § 18a UStG.

Has Germany enacted a domestic e-reporting system?

Structured electronic invoicing was deliberately introduced first to lay the groundwork for a future electronic VAT reporting system. However, the German government has not yet enacted the legislation for that system or announced its final technical model, operating authority, reporting flow, or domestic start date.

The BMF and other stakeholders are considering how invoice and transaction data could be reported digitally to the tax administration. Germany has not enacted a final domestic reporting interface, data schema, submission frequency, reporting deadline or mandatory network architecture. Businesses should not treat Peppol, a five-corner model or a certified service-provider structure as an established national reporting requirement.

When do the EU ViDA reporting requirements apply?

Under the EU VAT in the Digital Age (ViDA) package, digital reporting requirements and structured e‑invoicing for relevant cross-border intra‑EU B2B transactions apply from 1 July 2030. Germany will need to implement the required cross-border reporting capability by that date.

A domestic German reporting system may be introduced separately, but its timing remains unconfirmed. ViDA includes alignment requirements and transitional provisions for qualifying pre-existing domestic digital reporting regimes, including a 1 January 2035 milestone. This does not establish a 2035 German domestic reporting start date or prove that every future national system automatically benefits from the same transitional treatment.

Technical architecture & transmission channels

Unlike centralised models that mandate a single government platform, Germany uses a decentralised technical model:

Note: Germany’s current B2B e-invoicing legislation does not establish a domestic digital reporting obligation or a government clearance platform. The federal government has linked the e-invoicing rollout to the prospect of a later reporting system, and EU VAT in the Digital Age rules make future cross-border digital reporting highly relevant from 2030. Nonetheless, the eventual German domestic reporting model, including whether it uses a five-corner-style architecture, direct taxpayer reporting, service-provider reporting, Peppol infrastructure, or another channel, has not yet been legally determined.

Can German businesses exchange e-invoices directly?

Enterprises may exchange structured invoices via bilateral communication paths:

• Direct email transmission: Structured invoices, including compliant XML files or hybrid formats containing embedded structured data, may be delivered by email. The German rules do not mandate a particular email-security protocol, although parties may adopt appropriate security measures contractually or operationally.

• Point-to-point connections: Trading partners may agree on direct electronic channels, such as SFTP, AS2, APIs, EDI connections or supplier portals, provided the transmitted invoice satisfies the applicable structured-format requirements.

How does the Peppol four-corner network work?

The Peppol network offers a resilient infrastructure for German B2B exchange. Instead of establishing thousands of individual point-to-point connections, an enterprise can connect to a single accredited Peppol Access Point (Corner 2), which routes invoices securely across the network to the recipient's Access Point (Corner 3) using standard AS4 transport protocols. As indicated above, Peppol is not, however, the exclusive or legally mandated transmission channel for German domestic B2B invoices.

What is GEBA and how is it used for invoice routing?

To resolve routing challenges within the Peppol network, the Coordination Agency for IT Standards (KoSIT) developed the German Electronic Business Address (GEBA).

• Legal baseline: GEBA is founded on the German Business Identification Number (Wirtschafts-Identifikationsnummer - W-IdNr) regulated under Section 139c of the Fiscal Code of Germany (Abgabenordnung - AO). The W-IdNr is a unique, permanent identifier issued by the Federal Central Tax Office (BZSt) to every economic entity operating in Germany.

• Addressing scheme: GEBA is a W-IdNr-based electronic addressing approach intended for interoperable invoice routing. The precise scheme identifier, current registration status and supported version must be confirmed against the applicable official KoSIT and Peppol identifier specifications before publication.

• Granular routing: In addition to identifying the legal entity, GEBA allows companies to append sub-identifiers for specific operating branches, production plants, or accounts payable departments, ensuring that incoming invoices route automatically to the correct accounting workflow.

• Interoperability: GEBA may coexist with established identifiers such as GLNs and the Leitweg-ID used in B2G invoicing. Actual interoperability depends on the participant's registered identifier, network support and recipient configuration.

Accepted invoice formats

B2B invoices may use EN 16931-compliant or qualifying interoperable formats. For gross-price-based invoices affected by rounding constraints, the BMF's 2026 guidance, paragraphs 17–19, permits a temporary approach for invoices issued by 31 December 2027: the structured part may show aggregated amounts by VAT rate or exemption, while item-level details appear in a clearly referenced, human-readable embedded attachment. This is a conditional non-objection concession, not a general relaxation of required invoice content.

B2B suppliers can select a qualifying structured format, subject to contractual and public-procurement requirements where applicable. For construction invoices, the BMF currently accepts a structured description listing the individual trades and their totals, provided that a detailed bill of quantities appears in a clearly referenced, human-readable embedded attachment. A structured GAEB file may also be supplied.

Common German e-invoicing approaches include XRechnung, qualifying ZUGFeRD profiles, Peppol BIS Billing 3.0 and interoperable EDI formats:

1. What is XRechnung and when is it accepted?

XRechnung is the electronic invoicing standard developed by KoSIT specifically for the German public sector. It is an application profile (CIUS) of EN 16931 and is delivered exclusively as a structured XML file without a visual presentation layer. XRechnung is the principal German B2G invoicing standard. Federal procurement rules also allow other qualifying standards within the conditions of the ERechV, although the relevant portal and recipient requirements must be checked.

XRechnung supports two underlying syntaxes:

• UBL (Universal Business Language): XML syntax widely used across Europe and within the Peppol network.

• CII (Cross Industry Invoice): XML syntax developed by UN/CEFACT.

While initially created for Business-to-Government (B2G) transactions, XRechnung is fully valid for domestic B2B transactions under Section 14(1) UStG.

2. Which ZUGFeRD profiles qualify as e-invoices?

ZUGFeRD (Zentraler User Guide des Forums elektronische Rechnung Deutschland) is a hybrid format developed by the Forum for Electronic Invoicing Germany (FeRD) in close collaboration with the French partner FNFE-MPE, where Factur-X serves as the technically identical twin of ZUGFeRD..

Dominant in Germany and France, and endorsed for cross-border trade between these two nations and Switzerland, a ZUGFeRD file consists of two integrated components:

1. A visual, human-readable document in PDF/A-3 format (an ISO standard for long-term archiving).

2. A machine-readable XML file (zugferd-invoice.xml or factur-x.xml) embedded directly inside the PDF/A-3 container.

A ZUGFeRD invoice must use a qualifying version and profile and contain the applicable mandatory VAT particulars. Version 2.0.1 or later can be suitable, but selecting a supported version alone does not guarantee that the individual invoice is compliant.The qualifying profiles are:

• BASIC: While technically permissible under the mandate, this profile does not contain the full EN 16931 semantic data set. Because it is generally not accepted in B2G portals and carries a risk of rejection in B2B transactions, its use is not recommended.

• EN 16931 (previously described as “Comfort”): Fully corresponds to the semantic requirements of EN 16931 and is the recommended profile for seamless compliance.

• Extended: Extends EN 16931 to accommodate complex, industry-specific business requirements.

Important: The lower ZUGFeRD profiles (MINIMUM and BASIC-WL) do not satisfy the legal requirements of EN 16931. Invoices issued under these profiles do not qualify as electronic invoices under Section 14(1) UStG and are legally treated as “other invoices”.

B2G vs. B2B context: While ZUGFeRD (in applicable profiles) is ideal and widely adopted for B2B trade, lower profiles and hybrid formats are frequently unsupported or rejected by public-sector (B2G) submission portals, which predominantly expect pure XML (XRechnung). As such, ZUGFeRD should not be assumed acceptable unless the specific authority and channel accept it in a compliant profile.

Can businesses continue using EDI after 2027?

Electronic Data Interchange (EDI) systems based on legacy standards, such as EDIFACT, ODETTE, or VDA, are widespread throughout German automotive, manufacturing, and retail supply chains.

The legislature accommodated these existing investments under Section 27(38) UStG and the BMF guidance:

• Until 31 December 2027: Existing EDI arrangements may continue to be used, even if they do not strictly mirror the EN 16931 data model, provided both trading partners agree.

• From 1 January 2028: EDI formats remain permissible, but they must either conform directly to the semantic model of EN 16931 or allow the accurate and complete extraction of all mandatory VAT data into an EN 16931-compliant or interoperable output.

Penalties & fiscal non-compliance risks

Germany does not impose a separate automatic fine merely because a required structured e-invoice was issued as an 'other invoice'. The BMF Schreiben of 15 October 2026, paragraph 28, expressly excludes that conduct from the offence under § 26a(2) No. 1 UStG. Other failures, including not issuing an invoice or failing to issue one on time where required, remain subject to the applicable law.

Disallowance of input VAT deduction (Vorsteuerabzug)

An invoice defect may affect the recipient's input VAT deduction under § 15(1) No. 1 UStG. The outcome depends on whether the required VAT particulars are available, the nature of the defect, the applicable transition and the possibility of correction. A technical validation warning does not necessarily mean that input VAT must be denied.

Once mandatory issuance takes effect:

• If an in-scope supplier issues paper or an ordinary PDF after the applicable transition, the document is an 'other invoice' rather than a statutory e-invoice. An XML file must be assessed more carefully: a format defect can prevent e-invoice classification, but a business-rule error alone does not automatically do so for VAT purposes.

• Where a required e-invoice is replaced by an 'other invoice', the recipient's input VAT deduction must be assessed under § 15 UStG and the applicable BMF guidance. The position depends on the available invoice particulars, transitional relief and possible correction; automatic denial should not be asserted.

• A corporate tax audit (Betriebsprüfung) may result in amendment of the VAT assessment. Where the conditions of § 233a AO apply, additional-payment interest (Nachzahlungszinsen) may arise. The statutory interest rate for the relevant periods is 0.15% per month, equivalent to 1.8% annually.

When can German invoice-related administrative fines apply?

Although the BMF confirms that issuing an 'other invoice' instead of a required e-invoice is not itself the offence under § 26a(2) No. 1 UStG, other offences remain relevant. § 26a(2) Nos. 1, 2 and 5 UStG cover qualifying failures concerning invoice issuance, eight-year invoice retention and intra-Community recapitulative statements. Their respective statutory conditions and maximum fines must be assessed separately.

 Under § 26a(2) No. 1 UStG, intentionally or recklessly failing to issue an invoice, or issuing one late contrary to § 14(2), second sentence, may constitute an administrative offence. Under § 26a(3), the maximum fine for that offence is €5,000.

The BMF Schreiben of 15 October 2026, paragraph 28, expressly states that issuing an 'other invoice' instead of a required e-invoice does not constitute an administrative offence under § 26a(2) No. 1 UStG. The separate offence of failing to issue any invoice, or issuing it late, may still apply where its statutory elements are satisfied.

Can a buyer withhold payment over an incorrect invoice?

Whether payment becomes due only after receipt of a particular invoice depends on the relevant contract and applicable German civil and commercial law. The VAT-law requirement to issue a structured e-invoice does not, by itself, establish a universal condition precedent to every commercial payment.

A buyer may request a compliant e-invoice and may have contractual or statutory remedies where an invoicing obligation has not been met. However, a right to withhold payment must be established from the applicable contractual terms and civil-law conditions, including any relevant rights under § 273 BGB. Non-compliant invoices can therefore create commercial disputes, but withholding is not automatically justified in every case.

What are the consequences of failing to archive e-invoices?

Failing to preserve structured XML data in its original format throughout the mandatory 8-year retention period (calculated from the end of the year the invoice was issued) violates GoBD principles. Failure to preserve tax-relevant electronic invoices properly can lead to objections during a tax audit. An estimated assessment under § 162 AO depends on the statutory conditions, including whether the relevant tax bases can be reliably determined. An archiving defect does not automatically invalidate all bookkeeping records.

How businesses can prepare

Achieving sustained compliance requires deliberate alignment across information technology, tax accounting, procurement, and accounts payable.

How should businesses prepare to receive e-invoices?

Since 1 January 2025, domestic businesses have had to be ready to receive qualifying structured B2B e-invoices, including businesses exempt from mandatory issuance. Inbound processes should distinguish compliant invoice files, correctable VAT particulars and the different types of technical validation error:

• Verify that central invoice receipt mailboxes (e.g. invoices@company.de) are configured to ingest XML attachments without firewall stripping or security corruption.

• Deploy viewer tools or ERP plugins capable of converting raw XRechnung datasets into human-readable visual layouts for internal departmental approval. For hybrid ZUGFeRD invoices, ensure that the embedded structured data can be read, validated and reconciled with the visual PDF representation.

• Use suitable validation tools to distinguish syntax or format defects from business-rule errors and missing mandatory VAT information. Under the BMF's 2026 clarification, paragraphs 22–23, a business-rule error without a format defect does not automatically prevent a file from qualifying as an e-invoice for VAT purposes. Required tax particulars must still be correct and complete.

How should businesses prepare to issue e-invoices?

Organisations must evaluate when their mandatory issuance obligation begins:

• Determine whether the issuer's 2026 total turnover (Gesamtumsatz) under § 19(2) UStG exceeded €800,000. Issuers at or below that threshold may use the qualifying 2027 transition; larger issuers should assess their 2027 obligations, including the separate EDI relief and permanent statutory exemptions.

• Assess whether ERP and billing systems can map required VAT particulars to the correct EN 16931 fields using the KoSIT and FeRD mapping guidance. Check support for service descriptions, advance-payment deductions, embedded construction details, discounts, gross-price rounding and correction invoices.

• Confirm format and delivery agreements with customers. Determine which compliant structured format each customer can receive and which transmission channel is agreed. XRechnung and ZUGFeRD are common options, but the German B2B mandate does not prescribe either format or mandate Peppol. For a non-EN 16931 format, ensure the format meets the statutory requirement for correct and complete extraction of required invoice information into an EN 16931-compliant or interoperable format.

• Cleanse customer master data, ensuring that corporate legal names, registered addresses, tax numbers (Steuernummer), VAT identification numbers (USt-IdNr), and designated electronic routing identifiers (such as GEBA or Peppol IDs, where applicable) are complete and validated.

How can businesses set up compliant invoice archiving?

• Implement a compliant electronic archive that preserves tax-relevant invoice data and associated documents. Retain standalone XML invoices as XML. For hybrid invoices, retain the complete received hybrid file and any associated tax-relevant data.

• Ensure the archive supports access controls, audit trails, reliable retrieval and appropriate data protection. Retain invoices for the applicable statutory period, generally eight years under § 14b UStG, while checking whether other records require longer retention.

• Discontinue procedures that convert incoming electronic invoices into paper printouts for physical filing cabinets, as paper copies do not satisfy tax audit retention standards.

Should businesses use Peppol or an e-invoicing provider?

• Rather than maintaining costly point-to-point connections with commercial trading partners, assess integration with a Peppol-certified Access Point.

• If using Peppol, assess whether publishing a GEBA-based Participant ID is appropriate. GEBA is intended to support W-IdNr-based identification and routing in the Peppol network; it is not a compulsory registration for German B2B e-invoicing.

• Consider an e-invoicing service provider for conversion, validation and transmission where it improves operational reliability. Confirm that the solution supports current German VAT requirements and the BMF's 15 October 2026 clarifications; using a provider does not transfer the business's legal compliance responsibilities.

Conclusion

Germany's transition to electronic invoicing, spanning established public procurement (B2G) requirements and the nationwide B2B mandate, marks a fundamental transformation of the nation's commercial and administrative infrastructure. The Growth Opportunities Act incorporated structured e-invoice requirements into § 14 UStG, using EN 16931 and qualifying interoperable formats. Ordinary PDFs no longer satisfy mandatory e-invoice issuance requirements after the applicable transitions, but they remain permissible in situations covered by statutory exceptions.

Domestic businesses must already be able to receive structured B2B e-invoices. The next major issuance phase begins on 1 January 2027 for issuers exceeding the statutory turnover threshold, followed by the general phase on 1 January 2028, subject to permanent exemptions and the separate 2027 EDI transition.

Beyond immediate domestic compliance, establishing structured e-invoicing capabilities positions organisations for the upcoming European single market transformations under the VAT in the Digital Age (ViDA) initiative. Enterprises that upgrade their ERP architecture, standardise their master data, and partner with accredited transmission providers today will ensure regulatory compliance while unlocking genuine operational automation across their financial supply chain.
