TESCM integrates supply chain design with tax optimisation delivering significant increases in profits. It is based on the premise that incorporating tax arbitrage into supply chain structures (typically by optimising the location of the key supply chain functions, assets and risks) realises benefits well beyond conventional operational savings on their own. TESCM is especially topical as tax authorities are challenging traditional tax planning structures and products. At the same time businesses are changing their operating models in response to the economic downturn.
