International Taxation Service

International taxation is the study or determination of tax on a person or business subject to the tax laws of different countries or the international aspects of an individual country's tax laws. Governments usually limit the scope of their income taxation in some manner territorially or provide for offsets to taxation relating to extraterritorial income. The manner of limitation generally takes the form of a territorial, residency, or exclusionary system. Some governments have attempted to mitigate the differing limitations of each of these three broad systems by enacting a hybrid system with characteristics of two or more.
