HMRC has told employers using tax avoidance schemes involving "contracts for difference" to pay tax they owe to avoid legal action. HMRC said that a number of tax-avoidance schemes, based on contracts for difference, are being used by some businesses to provide tax free or tax reduced rewards to their employees. Over the last few years, a number of businesses have implemented contracts for difference ("CFD") / growth securities ownership plan ("GSOP") structures as a way of rewarding directors and key employees, normally in lieu of a bonus so that payments are subject to CGT rather than the normally higher rates of income tax and National Insurance contributions (NIC). As I will be dealing in many contracts for difference, my interest charges will be charged on my account and not split out by each contract. Therefore I have no way of allocating these charges to each contract, making the HMRC example quite unclear/basic. Is anyone able to answer how this would work, or point me to a more detailed source?
