Sorry, but not selling the Shares. My question was not about selling shares. I am selling the Goodwill. I am retaining the shares and then ceasing to trade.
So the company pays tax on the profit on Goodwill. The company can no longer trade. I am then taxed on withdrawing the funds on which the Company has paid tax. So assuming no offset costs, potentially taxed at 20%(CT) + 28% or18% or 10%(CGT) on the £200,000. So worst case pay 48%, best case 30%
