E-Invoicing in Germany 2027: Does the EUR 800k Rule Apply to You? (2026 Checklist)

Germany's 2027 E-Invoicing Threshold in Plain Language

If your business is active in Germany, 2026 is the year to verify whether the EUR 800,000 threshold will require you to switch your B2B invoice issuance process in 2027.

This article is based on the German Ministry of Finance (BMF) FAQ (updated 23.03.2026) and EN 16931 guidance. It is for operational orientation and does not replace legal or tax advice.

The timeline that matters

• Since 01.01.2025: Domestic businesses must be able to receive structured e-invoices.
• Until 31.12.2026: Senders may still issue other invoice types under transition rules.
• From 01.01.2027: If your prior-year turnover is over EUR 800,000, issuance obligations tighten.
• From 01.01.2028: E-invoicing is generally mandatory for domestic B2B invoicing, subject to statutory exceptions.

What counts as a compliant e-invoice

A compliant e-invoice must be structured, machine-readable, and processable electronically. Pure visual formats (for example, a plain PDF by email) do not meet the definition by themselves.

In practice, common formats are:

• XRechnung (XML)
• ZUGFeRD / Factur-X (hybrid PDF + XML, where structured data is leading)

Important scope and exception notes

• The core obligation targets domestic B2B transactions.
• B2C transactions are outside this specific mandate logic.
• Small-value invoices (up to EUR 250 gross) remain a special case under current rules.
• Specific legal carve-outs (for example in VAT law and implementing provisions) can apply.

2026 readiness checklist (quarter-by-quarter)

1. Q2: Confirm whether your prior-year turnover crosses EUR 800k and map affected document flows.
2. Q2: Validate that all mandatory VAT invoice data is captured in structured fields, not just attachments.
3. Q3: Decide your main format strategy (XRechnung vs ZUGFeRD/Factur-X) per customer segment.
4. Q3: Add pre-send validation to catch syntax and business-rule issues before dispatch.
5. Q4: Pilot with top customers/suppliers and document fallback operational procedures.
6. Q4: Train finance and support teams with real examples and escalation paths.
