Scrabble?! TOTALISATION

Definitions of TOTALISATION in various dictionaries:

Totalization agreements are international tax treaties that seek to eliminate dual taxation with regards to Social Security and Medicare taxes in the United States. These agreements are made in order to accommodate foreign workers who pay FICA taxes but receive no Social Security or Medicare benefits after reaching age 65. The agreements are made between the U.S. and other individual countries, and govern international taxpayers who earn money in the U.S. The goal of totalization agreements is to eliminate dual taxation on a foreigner's income made in the U.S. as well as provide proportional Social Security benefits for the same foreign workers. Issues considered to determine if a worker is covered under either Social Security and Medicare in the United States, or the social security system in a foreign country include where the worker resides and whether the employment in a foreign country is short-term or long-term. As of August 2017, U.S. has 26 active totalization agreements.
