Recently introduced exit taxes in Norway apply to capital gains on shares held by individual taxpayers emigrating from Norway, to the emigration of companies and to capital gains on the transfer of assets and liabilities outside the Norwegian tax area. This article describes and analyses these rules with special reference to EEA/EC tax law and their relation to tax treaties. In particular, the requirement, in some instances, to provide a guarantee for exit taxes, taxation without any option of deferral on the migration of companies, and taxation of the transfer of inventories and intangible assets are discussed. As regards tax treaties, the focus is on whether or not the alienation of the assets has taken place before the exit, and the relationship between exit taxes and tax treaty rules allowing for an extension of the tax liability.
