Do you derive the income for which you can claim treaty benefits?
Income may be derived by either the entity receiving the item of income or by the interest holders in the entity or, in certain circumstances, both. An item of income paid to an entity is considered to be derived by the entity only if the entity is not fiscally transparent under the laws of the entity's jurisdiction with respect to the item of income.
