Under "My data" in your customer account, you can change all the data you have already entered and enter new data.
Please always ensure that the data you have lodged is up to date and correct!
After each type of adjustment under "My data", we ask you to make sure that you tick the box confirming the correctness and completeness of all statements and then click on "Save" at the bottom right of the screen. You will then return to the menu of your customer account and can check the data by clicking on "My data" again. If all the data is now lodged the way you want it, the process was successful.
Good to know: In the customer account under "My data" you can determine, for example, how and whether you would like to be notified about the provision of new invoices.
