We own a house in Jersey and want to sell it before relocating to the UK. However, due to the market conditions, there is no demand and therefore, we will let the house for a year before selling. If we sell the house after a year, while we are in the UK, are we going to be subject to UK capital gains tax (CGT) on the profit from disposing of our Jersey house? 

Arthur Weller replies:  

You are going to be subject to UK CGT on the profit from disposing of your Jersey house if you sell it after coming to live in the UK. The reason is that a UK tax resident person is subject to UK CGT on their worldwide assets. See HMRC’s Capital Gains Manual at CG12400.
