Germany phases in mandatory e-invoicing for all domestic businesses

The guidance confirms that a phased transition period will apply before full mandatory e-invoicing takes effect.

Between January 1, 2025 and December 31, 2026, businesses may continue issuing invoices in non-electronic formats, including:

  • Paper invoices
  • PDF invoices sent via email

This flexibility is subject to recipient agreement, allowing businesses to adapt gradually.

Extended deadline for smaller businesses

Additional relief is provided for businesses with lower turnover.

Where the issuer's annual turnover does not exceed €800,000, the transitional period is extended until December 31, 2027.

This measure aims to reduce the compliance burden for smaller entities and allow more time for system upgrades.

Mandatory phase for domestic transactions

Following the end of the transitional periods, electronic invoicing will become mandatory for transactions between companies established in Germany.

This marks a shift toward a fully structured invoicing environment aligned with broader EU digital VAT developments.

Clarification on advance payments

The updated FAQs also address specific technical scenarios.

In particular, businesses will be permitted to include information on partial prepayments in an unstructured appendix attached to the final electronic invoice, even beyond December 31, 2027.

This provides practical flexibility for handling more complex invoicing cases.

Germany's updated guidance provides greater certainty on timelines and practical implementation, helping businesses plan their transition toward mandatory e-invoicing.

Companies should use the transitional period to assess systems, align processes, and ensure readiness for full compliance.
