Part II eliminates dual social security coverage, which occurs when a worker must pay social security taxes to both countries for the same earnings. This Agreement complies with the existing coverage provisions under the Laws of both countries except when necessary to prevent payment of social security taxes to both countries for the same earnings. The provisions in this Part retain the worker's social security coverage and taxation in the country to whose economy he or she has the more direct connection, while exempting the worker from coverage and taxation under the other county's system.
