W-8BEN

Hi HMRC team, I bought and hold US shares in Hong Kong securities firm before I arrived in the UK. I moved to the UK last summer but I did not file the updated Form W-8BEN about my new UK address, etc. May I know any problem/effect for me to file my self-assessment return under these two situations: 1. If I still hold US shares (no dividends declared from US shares at all times) 2. When I sell my US shares (profit or loss on disposal) Which form should be used for reporting of profit or loss on disposal on my shares? Thank you for your help.

Hi Pisces CHOY
if no dividend is paid out on the shares then there is no income to report.
If you then sell the shares and make a gain, you need to report this.
Please see guidance here:
Report and pay your Capital Gains Tax

Thank you.
