CGT on Company sharesave plans

Hi, I worked for Rolls-Royce and have a number of shares accumulated over the past 20 years through 5 year share save plans and share purchase plans. I paid up to £7/share for some of these shares in the early years of the plans. Rolls-Royce then had a rights issue in 2020 where their shares were devalued from approx £1.30 to 32p and shareholders were offered to an incentive to purchase shares at a reduced price to soften the blow to shareholders. I took the offer up and purchased another £12,000. I have no idea if I have to pay CGT although I honestly believe I have not made any money over the past 20 years. I have attempted to find out what price I paid for these shares by contacting Computershare who were the employee share plan provider but they could not help. At todays price I have approx £60,000. How do I attempt to work out or prove whether CGT is payable. Any advice please !

Hi,

Please refer to guidance at:

Tax when you sell shares

Shares and Capital Gains Tax (Self Assessment helpsheet HS284)

Thank you.
