‘Audit and accountancy firms who devise tax-avoidance schemes ruled unlawful have never faced official reprimand, The Independent can reveal. None of the so-called “Big Four” firms – PricewaterhouseCoopers (PwC), KPMG, Deloitte & Touche and Ernst & Young – has ever faced regulatory investigation for such schemes. Court rulings condemning unlawful avoidance schemes are regularly overlooked by regulators.’
