Registering your till system with the tax authorities

Since 1 January 2025, the statutory reporting obligation for electronic cash register systems has been in force in accordance with Section 146a of the German Fiscal Code (AO). All PC CADDIE cash registers must be reported via ELSTER by 31 July 2025 at the latest. For cash registers purchased on or after 1 July 2025, the deadline is one month after purchase.
 

To ensure you can fulfil this obligation, we have prepared all the necessary steps in PC CADDIE. The registration is carried out digitally via “Mein ELSTER” by uploading an XML file, which you can create directly in PC CADDIE. This file contains all the necessary technical information regarding the TSE connection.
 

Important: Please note that the purchase date of the till must also be entered as a field during registration. You can find this date in your accounting records. Alternatively – in consultation with your tax advisor – the date of TSE Installation may also be used. For long-standing PC CADDIE till systems, the legal requirements are fully met upon Installation of the TSE.
