Under the agreement, employment or self-employment is ordinarily subject to the laws on social security taxation and coverage of only the country where the worker performs the work (territoriality rule). A person working in employment or self-employment who would otherwise have dual coverage under the laws of both countries remains covered only under the laws of the country where they perform the work.

The agreement provides several exceptions to the territoriality rule to help ensure that a worker’s coverage is under the system of the country to which they have the more direct connection.
