Essential Components of a German Invoice
To ensure compliance with German tax laws, a standard invoice for VAT-registered businesses must include several mandatory fields. These include the full names and addresses of both the issuer and recipient, the issuer's tax number (Steuernummer) or VAT identification number (USt-IdNr), a unique and sequential invoice number, and the date of issue. Additionally, the invoice must specify the date of delivery or service, the quantity and type of goods or services provided, the net amount, the applicable VAT rate (e.g., 19% or 7%) and the corresponding VAT amount, and the total gross amount due. For small business owners (Kleinunternehmer), who are exempt from VAT under § 19 UStG if their turnover was below €22,000 in the previous year and is not expected to exceed €50,000 in the current year, invoices must explicitly state the reason for VAT exemption, typically with a phrase like "Gemäß § 19 UStG wird keine Umsatzsteuer berechnet." Simplified invoices, for amounts up to €250 gross, require fewer details, primarily the full name and address of the issuer, the date, quantity/type of goods/services, and the total gross amount including VAT.
