Understand German Invoice Requirements for Your Business

A German invoice is a tax document governed by the Umsatzsteuergesetz (UStG). Section 14 UStG sets the mandatory details a business must show, including supplier and customer names and addresses, tax number or VAT ID, invoice date, a unique invoice number, supply date, net amount, tax rate and tax amount.

Since 1 January 2025, German businesses must be able to receive structured e-invoices in domestic B2B transactions. Issuing obligations follow in stages through 2027 and 2028, depending on prior-year turnover. Advintek helps teams plan German invoice processes; confirm your own obligations with the Federal Ministry of Finance (BMF) or your tax advisor.

Frequently Asked Questions

1. What is a German invoice (Rechnung) under German VAT law?

A German invoice is a document issued for a supply of goods or services that meets Section 14 of the Umsatzsteuergesetz (UStG). It must contain specific details such as names and addresses, tax number or VAT ID, date, invoice number, description, net amount, tax rate and tax amount.

It must show the full names and addresses of supplier and customer, the supplier’s tax number or VAT ID, issue date, a unique invoice number, quantity and description of the supply, supply date or period, net amount by tax rate, the tax rate and tax amount, or a note on any exemption.

 

Since 1 January 2025, businesses must be able to receive e-invoices in domestic B2B transactions. The issuing duty applies from 1 January 2027 to businesses with prior-year turnover above €800,000, and from 1 January 2028 to all, with transitional rules. Verify details with the BMF.

 

A valid e-invoice must be structured and follow EN 16931. XRechnung (pure XML) and ZUGFeRD (PDF with embedded XML, in compliant profiles) are the common formats. A plain PDF or scanned image is not an e-invoice under the German rules.

 

The standard rate is 19% and the reduced rate is 7% for eligible goods and services. Some supplies are exempt. Small businesses under the Kleinunternehmer rule in Section 19 UStG may issue invoices without VAT and must state this on the invoice.

 

Yes. A small-amount invoice (Kleinbetragsrechnung) under Section 33 UStDV is allowed when the total does not exceed €250. It needs fewer details, such as supplier name and address, date, description, gross amount and tax rate. It is also outside the e-invoice duty.

 

Since 2025, invoices and other accounting vouchers must be kept for eight years under the Fiscal Code (AO) and Section 14b UStG. Books and annual financial statements still require ten years. Records must be readable and unaltered under the GoBD principles.

 

Under Section 13b UStG, the customer instead of the supplier owes the VAT in certain cases, such as specific construction services or certain cross-border supplies. The invoice must not show German VAT and must note that the recipient is liable for the tax.

 

Federal public bodies require e-invoices in the XRechnung format with a Leitweg-ID as the routing reference. Invoices are submitted through the federal invoice receipt platforms or the Peppol network. Always confirm the requirements of the specific authority before sending.

 

Advintek offers invoicing solutions for the German market. Before implementation, verify supported formats, delivery methods and integrations. Confirm your legal obligations with the Federal Ministry of Finance (BMF) or your tax advisor, as e-invoicing rules are being introduced in stages.
