In Germany, private investors have been liable to a flat tax on investment income since 1 January 2009. Statutory provisions require that in the event of a securities account transfer, the domestic custodian banks provide the institution receiving the accounts with the tax-related acquisition details and, where applicable, the originator’s allocation pots.
The custodian banks are therefore also responsible for keeping, maintaining, and processing data relevant to the German flat tax on investment income. At the end of 2008, customers of Clearstream Banking AG, Frankfurt (CBF) urgently requested CBF to develop a solution for the automatic transfer of tax-related data in the event of a securities transfer. In close cooperation with the market participants, this request lead to the development of Taxbox.
