Wachstumschancengesetz — legal foundation of the reform

The Wachstumschancengesetz (Growth Opportunities Act) is the statute that enacts the B2B e-invoicing obligation in Germany. Passed after an 11-month parliamentary saga (October 2023 — March 2024), it transposes Directive 2014/55/EU to the B2B sphere and amends §14 UStG to make EN 16931 the legal definition of an invoice.

Parliamentary genesis 2023-2024

The bill was filed by the federal government on 30 August 2023 under reference BR-Drucksache 433/23. Originally a comprehensive fiscal stimulus package (corporate tax cuts, reinstatement of declining-balance depreciation, R&D super-deduction), the e-invoicing transposition was a subsidiary article.

The parliamentary timeline is instructive of German trade-offs:

  • 30 August 2023 — Federal cabinet adopts the Regierungsentwurf (government draft).
  • 17 November 2023 — Bundestag passes the bill in third reading (322 yes, 230 no, CDU/CSU abstention).
  • 24 November 2023 — Bundesrat rejects on grounds of budget pressure on Länder (Vermittlungsausschuss convened).
  • 21 February 2024 — Vermittlungsausschuss (Bund/Länder mediation committee) reaches compromise: annual budget volume reduced from €7bn to €3.2bn, but the e-invoicing article kept unchanged.
  • 22 March 2024 — Bundesrat adopts the compromise (Resolution BR-Drs. 87/24).
  • 27 March 2024 — Presidential signature by Frank-Walter Steinmeier, publication in Bundesgesetzblatt I 2024 Nr. 108.

§14 UStG amendments

Article 23 of the Wachstumschancengesetz rewrites §14 of the Umsatzsteuergesetz (VAT Act, 1979) — articles on the establishment and retention of invoices. Three paragraphs are modified:

  • §14 (1) UStG — electronic invoice definition aligned with EN 16931 (text below).
  • §14 (2) UStG — mandatory B2B electronic invoicing from 1 January 2025 (reception) with transitional provisions.
  • §27 (38) UStG — transitional clauses: paper and "other electronic forms" (unstructured PDF, non-EN EDIFACT) allowed until 31 December 2026 (turnover > €800k) and until 31 December 2027 (turnover < €800k or EDIFACT by agreement).
text ustg-paragraph-14-2025.txt 
§ 14 (1) UStG (new wording effective 1 January 2025):

"An invoice is any document used to bill for a supply or other service, regardless of
how this document is referred to in commercial transactions. An electronic invoice is an
invoice that is issued, transmitted and received in a structured electronic format
allowing electronic processing. The structured electronic format of an electronic
invoice must comply with the European standard for electronic invoicing and the list of
corresponding syntaxes under Directive 2014/55/EU."

Synthetic translation:
- An electronic invoice under German law must be issued, transmitted and received in a
  structured format enabling automated processing.
- That structured format must comply with European standard EN 16931 and the syntaxes
  listed by Directive 2014/55/EU (UBL 2.1 and UN/CEFACT CII D16B).
- A non-hybrid PDF is NO LONGER an electronic invoice under §14 UStG.

Legal definition of an E-Rechnung

The legal weight of §14 (1) UStG is significant: from 1 January 2025, a classic PDF invoice (PDF/A or non-hybrid PDF) no longer has the legal status of a "Rechnung" in B2B transactions between German VAT-liable parties. It becomes a "sonstige Rechnung" ("other invoice"), tolerated during the transitional period (until 31 December 2026 or 2027 depending on turnover), but legally distinct from a true e-invoice.

Concretely, the following qualify as E-Rechnung under §14 UStG:

  • XRechnung — German CIUS of EN 16931, pivot format for B2G since 2020, extended to B2B (cf. XRechnung page).
  • ZUGFeRD ≥ EN 16931 profile — hybrid PDF/A-3 + embedded CII XML, from version 2.0.1 and the "EN 16931" profile (formerly "COMFORT" deprecated in 2.3). MINIMUM and BASIC WL profiles invalid for German B2B because they do not carry line-level detail.
  • EDIFACT (by bilateral agreement, transitional) — §14 UStG allows, until 31 December 2027, "other" formats if (1) the two parties agree contractually AND (2) a structured extraction of the EN 16931 fields remains possible. Typically EANCOM 2002 ORDERS/INVOIC subsets in German retail (Edeka, Rewe, Lidl, Aldi, Metro).

Phased timeline 2025-2028

§27 (38) UStG (transitional clauses) introduces an asymmetric schedule between reception and issuance obligations. This is the cornerstone of the German design: no big bang, but a ramp-up over 3 years.

From 1 January 2025, every German VAT-liable business must be able to receive and process a structured E-Rechnung. This reception obligation is immediate and has no threshold. Conversely, issuance remains optional until the 2027/2028 deadlines — the sender can keep using unstructured PDF during the transition if the recipient accepts.

BMF letter of 15 October 2024

The Bundesministerium der Finanzen (BMF — Federal Ministry of Finance) published on 15 October 2024 a key administrative letter referenced IV D 2 - S 7287-a/23/10001 :007. This 27-page document specifies how the amended §14 UStG should be applied and clarifies several grey areas in the statute:

  • Recommended pivot format: XRechnung CIUS v3.0 or ZUGFeRD ≥ 2.1.1 profile EN 16931. Any other structured format compliant with EN 16931 is acceptable.
  • Attachments: allowed in ZUGFeRD (hybrid PDF/A-3), not in pure XRechnung (UBL or CII XML) except via cac:AdditionalDocumentReference (UBL) or ram:AdditionalReferencedDocument (CII) elements.
  • Transmission channel: at the parties' discretion. BMF mandates no central platform. Acceptable channels: e-mail, SFTP portal, AS2, AS4, REST API, PEPPOL access point, EDI provider exchange.
  • Archiving: 10 years (§147 AO — Abgabenordnung), structured format retained as-is, no obligation to convert to PDF.
  • EDIFACT compliance by agreement: allowed until 31 December 2027 if (1) written bilateral agreement, (2) the format allows extraction of mandatory EN 16931 fields. BMF cites EANCOM 2002 INVOIC subsets as valid candidates subject to mapping.

Penalties and exemptions

The penalty regime relies on the classic arsenal of German tax law (§§369 ff. AO) and VAT (§14c UStG). No specific "e-invoicing" fine was introduced by the Wachstumschancengesetz, unlike France or Italy.

  • Vorsteuerabzug (input VAT deduction) — primary risk: from 1 January 2027 (turnover > €800k) and 2028 (universal), an invoice received in an unstructured format may be rejected by the tax authority as a basis for input VAT deduction. The BMF letter confirms: no Vorsteuerabzug without a proper E-Rechnung.
  • Bußgeld §379 AO — administrative fine up to €5,000 for breach of bookkeeping obligations (including invoice retention). Triggered in repeated or collusive scenarios.
  • Exemptions — invoices < €250 incl. VAT (Kleinbetragsrechnung, §33 UStDV): PDF still allowed. B2C between private parties: out of scope. Kleinunternehmer §19 UStG (turnover < €22,000 / year): exempt from issuance but must still be able to receive.
