On 6 September 2017, the German government issued a regulation to supplement the e- invoices law and clarify various details.
This supplement is known as the e-Invoicing regulation.
As mentioned above, the e-Invoicing Law came into force on 27 November 2018. Since then, the regulations prescribed there have been valid for federal ministries and constitutional bodies. The E- invoices law has been in force for all federal authorities since November 2019.
Invoices of 1,000 € or more can be transferred to the federal government via e-Invoicing. From 27 November 2020, all suppliers who issue invoices to the federal government must submit them in certain formats, as so-called X-invoices.
