Dear Client!
You can find out more about your tax account registered with the National Tax and Customs Administration (NTCA) in several ways. You most often hear about your tax account that can be consulted electronically (via the Client Portal/ÜPO), a tax account statement or a payment notice on default interest sent by post. We would like to help you interpret the data provided, for example the current debt or overpayment. In order to make it easier for you to navigate, we have grouped the information related to the tax account by topic on this website.
