Eu rules apply to all EU Member States, i.e. where bilateral agreements exist, they are not mentioned here. A number of factors determine the nature of social security contributions that must be paid independently of employers and workers, as well as the monetary consequences. (Figure 1 shows some examples of different income level rates in the sample). To understand the complex situation that can occur when a worker is sent to an international mission - solely on the basis of the cost of social security - you consider charts 2 and 3 below, which show the social contributions of workers and employers as a percentage of income in a number of countries of origin. The charts use US$150,000 and the corresponding monetary value in the countries concerned. Each totalization agreement has an exception for international staff. Under this exception, a person temporarily transferred to the service for the same employer in another county is covered only by the national form he or she received. Workers and employers continue to pay contributions to the national social security system. 1. This Agreement does not apply to persons who, under the Vienna Convention of 18 April 1961 (4) or the Vienna Convention on Consular Relations of 24 April 1963 (5), are exempt from the social security law of the contracting party in the territory of which they reside or reside. Social security contributions can become, depending on the country of origin and the host country, a very expensive aspect of an allowance abroad.
Due to a large number of totalisation agreements that set specific conditions, confusion over social security contributions and benefit rights has gradually subsided - with the costs of employers - but the subject still often requires the advice of experts with expertise in this area. This last point concerns multinational organisations which, because of the unique consequences of an international commitment, claim a financial profit or loss of the expatriate - that is, minimise any financial gain or loss of the expatriate - and therefore have an additional financial burden when they fulfil the commitment of the host country as part of its foreign policy.
