Date used for counting CGT tax

I sold US stock on 2 Apr 2021, settlement was done on 6 Apr 2021, and bank credited to my a/c on 7 Apr 2021. For calculating capital gain tax, which date should I use? It would count towards different tax years, as 2021/22 tax year or 2020/21 tax year? Thank you.

Hi,
 

You would use the date of disposal, not date of payment, so if this was 02/04/21, this would be reported in the 20/21 year.

Thank you.
