Moving to US - CGT on Investments?

Hi, I am a UK national currently living in Qatar. While living in Qatar I have been investing my income into share funds in a UK-based platform. I am due to move to the US in the new year. Can you please help with the following questions? 1. If I decide to leave the investments, and sell while in the US in the future, will I have to pay UK CGT? 2. If I decide to sell the investments before I move to the US, will I have to pay UK CGT? 3. Will I have to pay UK and US CGT in either of the above scenarios? Thank you for the help.

Hi JH007,
If you are not resident in the UK, when you dispose of assets that are not residential property and land, you will not pay Capital Gains on the disposal, provided you do not return to the UK within 5 years.
You will need to declare the disposal in your country of residence and pay Capital Gains tax there.
Thank you.
