A common error among tax advisers is the expectation that tax law in a foreign country is applied in a straightforward way. For example, if a tax treaty provides that a foreign country will provide a foreign tax credit for taxes imposed by the other country, it seems clear that foreign tax will be reduced by that credit. Regrettably, this is not always the case. Francesco Capitta, who is Of Counsel to Facchini Rossi Michelutti, Studio Legale in Milan, and Andrea D’Ettorre, who is an associate at the same firm, explain that, in Italy, a decision of the Supreme Court was required in order to allow an Italian resident individual to reduce Italian tax by a foreign tax credit for U.S. income taxes withheld on U.S. source dividend income. Remarkably, there was a logical reason for the denial, but it was invalidated in the case.
