The Tests for the Determination of the Scope of Taxes: The Territorial Location of the Object and the Personal Link of the Taxpayer to the Country
The scope of income tax is generally determined in the light of two criteria: the personal link of the taxpayer to the country and the link between the income and the territory of the country imposing the tax. The imposition of tax on the basis of the second of these criteria is known as “the source of the income” approach.A similar term, the doctrine of “source”, was used in the British income tax system to denote a different theory. That theory was based on the idea that all income must have a “source” and that no one ought to be taxed in a given year unless it can be shown that he had a source from which income could be derived during that year. It should be noted, however, that notwithstanding the linguistic resemblance between the terms used for the two theories, in fact they deal with different matters. Hence, though perhaps historically related, the two concepts should not be confused.
