Why the new regulations?
Few requirements currently apply to the functions and structure of cash register systems, and inspections conducted by the Norwegian Tax Administration have revealed that cash register systems are set up in a way which makes it possible to conceal cash sales. The new rules will make it more difficult to manipulate a cash register system in order to avoid tax and duties.
List of cash register systems
You will find the list over cash register systems (in Norwegian) that the suppliers have declared to be in compliance with the new rules.
How to declare that your cash register system is in compliance with the new rules (suppliers)
If you are a supplier, you need to log on to Altinn and send the form "Systemleverandørers produkterklæring av kassasystemer - RF-1348" (in Norwegian) to confirm that your cash register is in compliance with the Norwegian Cash Register Systems Act and the Regulations. If a supplier does not submit a product declaration, or the cash register system fails to fulfill the requirements, the Norwegian Tax Administration could issue a penalty fine. See the legislation on cash register systems for more information. This is how foreign companies get access to Altinn.
The Norwegian Tax Administration has prepared guidelines for the design of cash register systems. You can find the design specifications on this website (in Norwegian). Here you will find all the descriptions about documentation and the code scheme for standard export-XML (SAF-T) adn digital signature.
