E-invoicing is becoming mandatory in Germany

Under the Wachstumschancengesetz, structured e-invoices apply to domestic B2B supplies. Summary based on the Federal Ministry of Finance (BMF) FAQ.

Since 1 January 2025 — receive

Domestic businesses must be able to receive e-invoices. A plain PDF alone is no longer an “E-Rechnung”; the format must be structured and machine-processable (EN 16931 — e.g. XRechnung or ZUGFeRD from version 2.0.1).

Issuing — phased until 2028

Through 31 December 2026, issuers may still use other invoice forms (paper always; other electronic formats only with the recipient’s consent). Businesses with prior-year turnover up to €800,000 may use that option until the end of 2027. After the transition, domestic B2B e-invoices become mandatory.
