Capital gains on shares: If you bought £20,000 of shares in a quoted company, which you did not hold in an Isa, and you subsequently sold them for £100,000, you would be liable for CGT.
Your gain would be £80,000 minus your annual CGT allowance (£11,100), which comes to £68,900. Depending on your income tax status, you would pay either 18 or 28 per cent of this, so £12,402 or £19,292.
