Mandatory e-invoicing in Germany: Abacus is ready - are you?

minutes reading time

An important innovation in B2B business transactions is coming into force in Germany: From 1 January 2025, the receipt of e-invoices in accordance with the European standard EN 16931 will be mandatory for all German companies in B2B business. These include formats such as ZUGFeRD, XRechnung and similar standards. Conventional PDF invoices do not fulfil this standard. There is a transitional period until the end of 2026 for sending e-invoices; for small companies, this period is extended until the end of 2027.

What is behind the legal obligation for e-invoicing in Germany?

From 1 January 2025, the electronic receipt of invoices in business transactions between companies will be mandatory in Germany. Essentially, the e-invoice obligation requires invoices to be issued, transmitted and received in a structured electronic format, which enables automatic processing. These include formats such as ZUGFeRD, XRechnung and similar standards that are compatible with the European standard EN 16931. This standard ensures the interoperability of invoice data at national and European level. Conventional PDF invoices do not comply with this standard. 

It will still be possible to send and receive paper invoices or e-invoices in various formats until 31 December 2026. However, it should be noted that paper invoices are no longer favoured and the recipient is obliged to accept an e-invoice. For electronic formats that are not EN 16931-compliant, such as PDF documents, the explicit consent of the recipient must still be obtained. Until 31 December 2027, companies with an annual turnover of less than 800,000 Euro can benefit from a special regulation that gives them more time to implement the necessary adjustments. Electronic Data Interchange (EDI) is also permitted after 2027, provided the format is EN 16931-compliant and compatible. This is the case with the EDIFACT format, for example. Companies that do not use a legally compliant EDI format will be granted a transitional period until 31 December 2027 to make the necessary adjustments. 

The e-invoicing obligation does not stipulate a transmission channel. They can also be sent by e-mail, provided the format conforms to the standard.

Who is affected by this obligation?

The obligation to e-invoice applies to all companies (invoice issuers and invoice recipients) with a registered office or branch in Germany that are active in the B2B sector. A purely VAT registration in Germany without a branch does not constitute an obligation to e-invoice. This applies to large companies as well as small and medium-sized enterprises. Invoices up to an amount of 250 Euro and certain tax-free services in accordance with the Value Added Tax Act are exempt from this obligation.

What will change for Swiss companies?

The following changes apply to Swiss companies that maintain business relationships with German companies:

Invoicing to German companies

The obligation to e-invoice under German law only applies to invoices where both parties (invoice issuer and invoice recipient) are based in Germany. This obligation does not apply to invoices from Switzerland to a German company, as the invoice issuer is not based in Germany.

Despite the lack of a legal obligation, the Swiss invoice issuer and the German company can contractually agree on the use of electronic invoices. In this case, Abacus recommends adapting the invoice to the German legal requirements, such as the EN 16931-compliant ZUGFeRD or XRechnung formats, so that the invoice can be processed further without any problems.

Receipt of invoices from German companies

Swiss companies are not obliged to receive electronic invoices in accordance with the German E-Invoicing Act, as this only applies to companies based in Germany. Invoices from German companies to Swiss companies can continue to be issued in conventional formats such as PDF, unless otherwise agreed. However, both parties can agree to use electronic formats such as ZUGFeRD or XRechnung to increase efficiency and automate processes. Under tax law, however, such invoices must still fulfil the requirements of Swiss VAT law.

Swiss companies with branches in Germany are therefore advised to review their invoicing processes and adapt them if necessary in order to fulfil the new requirements and ensure smooth business transactions with German partners.

What will happen in the EU and Switzerland? 

As part of the "VAT in the Digital Age" (ViDA) initiative, the European Union is planning the gradual introduction of a cross-border electronic reporting system for invoices within the EU. However, as a non-EU member, this system only affects Switzerland indirectly. 

In future, Switzerland could introduce its own regulations on electronic invoicing in B2B business in order to simplify cross-border trade and strengthen the digital single market. However, there is currently no general obligation to accept and send electronic invoices.
