Information for private individuals who are customers of Norwegian financial institutions

  • Print

Since 1 January 2016, Norwegian financial institutions have been obliged to record information regarding the tax residency of their customers and whether they are US citizens. They must also request the foreign tax identification number of these customers. The account information must be reported to the Norwegian Tax Administration, which will forward the information to the tax authorities in the customer's home country. The purpose of these rules is to ensure that financial income and assets in Norway are taxed correctly in the customer's home country. You may therefore be asked to state where you are resident for tax purpose, among other things.


Why do I have to give my foreign identification number to the financial institution?

Authorities in most countries currently use different identification numbers to identify individuals. A national ID number is used to identify people in Norway. Foreigners who do not live in Norway will instead be given an individual D number. The tax authorities in other countries use identification numbers to identify people in the same way. You must state your foreign identification number so that the tax authorities in the place where you are tax resident can link the account information to you.

Identification numbers may either be used by the tax authorities alone, or by the tax authorities and other agencies and institutions in the country concerned, as is the case in Norway. You will normally find your identification number on documents sent to you by the tax authorities in your country of residence, but the number may also be given on passports, national identity cards, driving licences and other official documents.

The tax authorities in Sweden, for example, use a personnummer, Denmark uses a CPR number and Poland uses a PESEL number as an identification number.

Such identification numbers are often referred to as a TIN ("Taxpayer Identification Number"). Not all countries use such identification numbers. More information regarding the identification numbers used in various countries can be found here.
