Moo, if you have a share dealing account then a copy of your dealings are sent to the HMRC who rely on you to inform them if any profits that you make affect your capital gains allowance. The HMRC do not have the resources to vet everything and rely on you being honest in filling in your own returns, however if you are caught not complying then they can go back and check 4 years for genuine mistakes but can go back up to 6 years for carelessness and then 20 years for deliberate avoidance. The penalties can be very severe so I wouldn't like to be anyone who has chosen deliberately not to pay tax on their share dealings
