Revenue Ruling 2004-76 held that a foreign corporation (A), formed under the laws of country X, could not claim the benefits of the income tax treaty between the US and country X if under the income tax treaty between country X and country Y, it is treated as a resident of country Y. This ruling may limit planning options for companies that are treated as a resident under the laws of more than one country that has entered into a modern income tax treaty with the US. The ruling may also cause headaches for US withholding agents.
