Norwegian financial institutions are obliged to record information regarding where their private customers are resident for tax purposes and whether they are US citizens. Financial institutions must report this information, together with information relating to accounts, to the Norwegian Tax Administration annually in the same way as for information that must be precompleted in the Norwegian tax return.
The purpose of the rules is to ensure that the financial affairs and insurance policies (financial accounts) of foreign customers with Norwegian financial institutions are taxed correctly in the customer's home country. The Norwegian Tax Administration therefore sends the account information to the tax authorities in the customer's home country.
The rules have been introduced based on international agreements that Norway has entered into with other countries.
