European Union savings taxation
In the European Union, member states have concluded a multilateral agreement on information exchange. This means that they will each report (to their counterparts in each other jurisdiction) a list of those savers who have claimed exemption from local taxation on grounds of not being a resident of the state where the income arises. These savers should have declared that foreign income in their own country of residence, so any difference suggests tax evasion.
(For a transition period, some states have a separate arrangement. they may offer each non-resident account holder the choice of taxation arrangements: either (a) disclosure of information as above, or (b) deduction of local tax on savings interest at source as is the case for residents).
A recent study by Business Europe confirms that double taxation remains a problem for European MNEs and an obstacle for cross border trade and investments. In particular, the problematic areas are limitation in interest deductibility, foreign tax credits, permanent establishment issues and diverging qualifications or interpretations. Germany and Italy have been identified as the Member States in which most double taxation cases have occurred.
