If income is still taxable in both countries, double taxation is granted by the tax holder`s country of residence by referring to the tax due in the country of origin of the income. Under UK regulations, he is not domiciled and, in the United Kingdom, he is taxable only on his income from the United Kingdom. Mark remains resident in Germany and is therefore taxable on his global income. The Double Taxation Convention tells Mark that the UK has the primary right to tax income and that if Germany also wants to tax it, the foreign tax credit method should be used to avoid double taxation. In order to conclude an agreement to avoid double taxation and to prevent tax evasion with respect to income taxation (3), the income, profits and capital of a business in one of the territories whose capital is directly or indirectly owned by a territory or territory resident will not be subject to higher or heavier taxation than other companies in that first territory are or may be exposed to in this area. which relates to the same income, profits and capital. In particular, people using the alternative tax method should pay a flat tax of 100,000 euros per year, regardless of the amount of their foreign income from source. If a parent uses the corresponding provisions, they should pay a flat fee of 20,000 euros per year. The use of these provisions must not exceed 15 tax years. As has already been said, even if there is no double taxation agreement, tax breaks can be made possible through a foreign tax credit. It has nothing to do with labour tax credits or child tax credits.
ARTICLE XVI-1. Nationals of one of the contracting parties are not subject, in the territory of the other contracting party, to a tax or related requirement that is otherwise heavier or heavier than the imposition and related requirements to which the nationals of the latter contracting party are or may be subject. ARTICLE XV.- (1) The tax authorities of the parties exchange this information (since it is information available to them in the context of normal administrative procedures under their respective tax laws), as is necessary to implement the provisions of this Convention or to prevent fraud or to manage legal provisions against circumventing the law concerning the taxes that are the subject of the convention. All the information thus exchanged is treated as secret and cannot be disclosed to anyone other than those concerned with the taxation and collection of taxes covered by the Convention. No information can be exchanged that would reveal trade, trade, industrial or professional secrets or business procedures. The Greek source income of persons subject to the alternative tax method should be recorded in the annual income tax return and taxed according to its classification, while their foreign source income is not declared and is taxed on the basis of the flat tax.
