The benefit of treaty protection is restricted to the amount of income which is eventually subject matter of taxation in the source country. This is all the more relevant for the reason that in a situation in which territorial method of taxation is followed by a tax jurisdiction and the taxability for income from activities carried out outside the home jurisdiction is restricted to the income repatriated to such tax jurisdiction, as in the case of Singapore, the treaty protection must remain confined to the amount which is actually subjected to tax. Any other approach could result in a situation in which an income, which is not subject matter of taxation in the residence jurisdiction, will anyway be available for treaty protection in the source country
