Singapore Sling (tax avoidance)
A Singapore Sling is a tax avoidance scheme in which a large multinational company sells products to a subsidiary owned by them in a jurisdiction with lower tax rates, which acts as a 'marketing hub'. The subsidiary then sells the product to end users, marking up its value and attributing the mark-up to various marketing activities undertaken by the subsidiary.
