Invoice Requirements in Germany: Legal Rules for 2026

Germany ties invoice content to §14 UStG and pairs it with GoBD record-keeping. If mandatory details are missing, your buyer may lose input VAT and you face deeper scrutiny in a Betriebsprüfung. Electronic formats are shifting as B2B e-invoicing obligations phase in. Triangulation and call-off stock arrangements need precise narrative on the face of the document. This overview targets 2026 practice for mainstream taxable supplies—confirm cross-border and special schemes with your Steuerberater, especially OSS and IOSS distance sales. It is general information, not legal advice.

Required fields

Full invoices generally need seller and buyer name and address; Steuernummer and/or USt-IdNr.; invoice date; unique sequential number; description of goods/services with commercial detail; Leistungsdatum (supply date—do not omit even if identical to the invoice date); net amounts grouped by tax rate; rate (e.g. 19% or 7%); tax amount; gross total; and references to advance payments or reductions where relevant. Small-value invoices under €250 follow simplified rules. Intra-EU B2B may require reverse-charge wording where applicable. Construction and real-estate-like services to consumers can trigger invoice duties even when the counterparty is not VAT-registered—map your case before you ship a bare receipt.

Tax rules (VAT/GST/sales tax rates)

Standard VAT (MwSt/USt) is 19%. A reduced 7% rate applies to defined categories such as certain food, books, passenger transport, and hotel accommodation as specified by law. Exempt supplies require correct legal references and must not show VAT improperly. Intra-Community supplies and some services shift liability under reverse charge. Mixed supplies must split lines and rates clearly. If you use cash accounting or special schemes, your invoice still must make the tax base and rate transparent for the buyer's audit trail.

Language requirements

German law does not strictly require German, but tax offices may demand German explanations during audits. Domestic B2B almost always uses German; bilingual invoices help international customers without sacrificing clarity. Keep legal references in official German phrasing when citing exemptions or reverse charge.

Digital invoicing rules

GoBD requires traceable, unaltered storage of electronic invoices—treat PDF/XML originals as legal records, not disposable email attachments. Germany mandates structured B2B e-invoicing on a phased schedule using XRechnung and ZUGFeRD; even before your send obligation, customers may require machine-readable invoices. Retention is typically ten years. Audit trails should connect issued documents to your DATEV, ERP, or bookkeeping export without manual re-keying. If you receive PDF scans, assess whether they meet GoBD evidence standards versus native electronic originals. Cross-check your invoice numbering with your general ledger so Betriebsprüfer can reconcile series, credit notes, and cancellations in one pass. Monitor the Federal Ministry of Finance and the finance administration for implementation dates and technical notes.

Penalties

Non-compliant invoices can invalidate buyer deductions, forcing credit notes and reputational damage. Missing Pflichtangaben, late issuance (often within six months of supply for B2B), or GoBD violations may yield fines and estimated assessments. Serious misconduct escalates sanctions. Where intra-EU chains are involved, inconsistent USt-IdNr. validation or reverse-charge labelling can trigger double taxation or refund delays—treat invoice text as part of your compliance control alongside VAT returns.
