CGT on RSUs

Hello, The company I work for grants RSUs that vest twice a year. They sell a proportion of the shares when they vest to pay UK income tax and National Insurance. All of this appears on my P60. I sell the remaining shares immediately (on the day they vest) and transfer the money to my bank account. Do I need to pay Captial Gains Tax on the sale of my shares? Do I need to put this in my tax return anywhere?

Just pinging HMRC to answer, please.

Hi Matthew,
If you sell the shares immediately upon vesting, there is no Capital Gains Tax to pay.
This ensures that there is no gain to tax.
If you hold on to them and sell then sell at a later date, there could be Capital Gains Tax liability.
Thank you.
