HANOI, May 30 (Reuters) - Samsung and other foreign companies are pushing Vietnam to introduce a multi-million-dollar reform that would compensate them for higher levies they face from next year under a global overhaul of tax rules, a source involved in the talks said. The discussions precede the introduction from January of a minimum tax rate of 15% for large multinationals under a landmark global reform led by the Organisation for Economic Cooperation and Development (OECD). The global rule requires companies paying less in a low-tax jurisdiction to face a top-up levy in their home country. Samsung's tax rate varies by district, and ranged between 5.1% and 6.2% in 2019 in the two northern provinces where it produces smartphones, according to government data cited by local media. Smaller companies that are not within the scope of the new global rules may also receive handouts, the source said.
