Under the FATCA regulations, financial institutions are under an obligation to treat customers who do not provide the information requested as US reportable persons. This means that Nordea will report the same information about such customers to the local tax authorities as it will about those who have provided documentation confirming their status as US persons. In some exceptional circumstances, financial institutions may be required to withhold tax on certain payments from US sources coming into accounts held by customers who have not provided the information requested.
