The concept of “belonging” is very important in VAT as it determines where a supply takes place and thus the rate applicable and the country in which is due. (The so-called “Place Of Supply, or POS). It is necessary, for most supplies, to establish where both the supplier, and the recipient belongs. Because this is a complex area of VAT it is not difficult to be overpaying tax in one country, not paying tax where it is properly due, or missing the tax issue completely.
