Germany has bilateral social security agreements with several countries to coordinate social security coverage and benefits for people who work or have worked in more than one country. These agreements often cover issues like pension benefits, disability benefits, and health insurance, and are designed to prevent double social security contributions and ensure that individuals do not lose their social security rights when moving between countries.
Germany has bilateral social security agreements with Australia, Brazil, Canada (including a separate agreement with Quebec), Chile, China, India, Israel, Japan, South Korea, Morocco, Montenegro, North Macedonia, Philippines, Serbia, Tunisia, Turkey, United States of America, and Uruguay.
For these countries, a German citizen can continue utilizing the German social security system. For all other countries, the German citizen has to contribute to the country of employment's social security system.
