The goal of all U.S. totalization agreements is to eliminate dual social security and taxation, while maintaining coverage for as many workers as possible under the country where they are likely to have the most ties, both at work and after retirement. Any agreement aims to achieve this objective through a series of objective rules. They must take into account the terms of the corresponding agreement to define the rules in force – the relevant agreement is the agreement between the UNITED Kingdom and the country in which the worker has contributed (although the situation may be more complex in three or more countries). In general, these agreements provide that the migrant must pay NIC, unless all these agreements are based on the concept of shared responsibility. Responsibility-sharing agreements are reciprocal. Under each agreement, partner countries make concessions to their social security qualification rules so that those covered by the agreement have access to payments that they may not be eligible for. The responsibility for social security is thus distributed among the countries in which a person has lived during his or her working years and where the person is able to obtain potential rights. In general, it is possible to access a pension from one country in the second country, although the paying country retains some discretion with regard to the exchange and delivery mechanisms used. The detached house rule may apply if the U.S. employer transfers a worker to work at a foreign branch or in one of its foreign subsidiaries. However, in order for U.S. coverage to continue when a transferred employee works for a foreign subsidiary, the U.S.

employer must have entered into a Section 3121 (l) agreement with the U.S. Treasury Department with respect to the foreign subsidiary. Under these agreements, Australia equates social security periods/stays in these countries with periods of Australian residence in order to meet minimum qualification periods for Australian pensions. In other countries, periods of Australian working life are generally counted as social security periods to meet their minimum payment periods. Typically, each country pays a partial pension to a person who has lived in both countries. There is a list of countries with which the UK has GOV.UK social security agreements. You can contact the International Pension Centre for more information on the situation when you enter such a country. The list of countries with which the Uk has a social security agreement is on GOV.UK.

Although the agreements with Belgium, France, Germany, Italy and Japan do not use the rule of residence as the main determinant of self-employment coverage, each of them contains a provision guaranteeing that workers are insured and taxed in a single country.
