Assume that you have a company which has ceased trading and is left with a cash balance. You could extract most of the cash by paying a dividend, but that would be inefficient for tax purposes (resulting in tax rates of up to 39.35%). So, instead, you decide to wind the company up and receive the proceeds as a capital distribution, taking advantage of the lower capital gains tax rates (generally at 10% or 20% depending on the circumstances). Surely that is legitimate?
