HMRC has collected a not insignificant £5bn through its Fraud Investigation Service, but notwithstanding that, £16bn was still lost through tax fraud last year. It is clear that HMRC has an almost never ending battle on its hands and also that its only something they can address with the help of others, including professionals like accountants/lawyers who might have knowledge of such matters or insolvency practitioners who can identify, and assist in recovering money from, tax avoidance and evasion.
