Electronic invoices are subject to the same retention requirements as paper invoices. According to section 14b of the VAT Act (Umsatzsteuergesetz, UstG), invoices must be stored for ten years. In order to comply with data protection law, invoices are fully deleted from the portal 28 days after they have been created or have changed their status. The different periods are due to different system requirements.
Invoices can be downloaded before the retention period expires.
In the OZG-RE portal, all submitted invoices can be downloaded via the menu “Invoice status”.
