Reporting the gain from a share incentive plan

Hello With my previous employer in France I had a share incentive plan with matching shares. I aquired the shares in 2010 and 2011, and sold them in December 2023. I am a UK fiscal resident and I was when I sold the shares. From information on HMRC’s website I understand that the gain is not taxable in the UK: “If you get shares through a Share Incentive Plan (SIP) and keep them in the plan for 5 years you will not pay Income Tax or National Insurance on their value.” “You’ll not pay Capital Gains Tax on shares sold, if they were kept in the plan until the point of sale.” which all seems to be my case. My question is: although I don’t have to pay CGT, do I still need to report the gain to HMRC? Thank you for your help.

Hi,
Yes, you should report the disposal on a self assessment tax return, even when there is no tax to pay.
Thank you.

Thank you for your reply. Could you please tell me where in the tax return I should report this? I looked but couldn't find the right section. Thank you for your help.

Hi
As there is no taxable gain, you would report the disposal as a free hand note in box 19 of SA100, page TR7 or the online equivalent box for additional information.  In this way you are declaring the disposal in the interest of full disclosure and ensuring it is not included in the tax calculations.

Thank you
