On the move to Houston in July We have our family home in UK on the market to sell so we can buy a smaller property ready for the next stage in our lives now the family have left home. As we have had the property many years and it is the London area, it has obviously appreciated in value. Are we liable to pay capital gains tax if we move to the US? If my husband moves in July but I wait until the end if the tax year, does that make a difference? If we are selling with a view to buying a similar home, does this make a difference?
