Tax-related capital flight is defined as the process whereby wealth holders perform activities to ensure the transfer of their funds and other assets offshore rather than in the banks of their country of residence and thereby avoid or evade taxation in the country where the wealth is generated. The result is that assets and income are often not declared for tax purposes in the country where a person resides or where a company has generated this wealth. Capital flight, tax evasion and tax avoidance or ‘aggressive tax planning’, are intimately linked phenomena.
