Tax Implications of Trading on Behalf of a Friend

Dear HMRC, I am writing to seek clarification on the tax implications of an arrangement I have with a friend. My friend would like to provide me with capital to trade on their behalf. I do not receive any compensation for this, and all profits and losses are returned to my friend. Could you please advise on the following: Who is liable for reporting and paying taxes on any profits made from these trades? Are there any specific documentation or records we should keep? Are there any particular tax rules or regulations that apply to this kind of arrangement? Thank you for your assistance. Sincerely,

Hi jgonzalezf87,
If the trading is in your name then it will be you who is liable.
Thank you.

Thank you for your help. So, if I understand correctly, the process is that she should transfer/gift the crypto capital to me and pay tax on any capital gains at that point. Then, I trade with the amount. When I need to return the crypto capital, I would pay tax on any capital gains made since she transferred it. Thank you in advanced. Best regards.

Hi Javier Gonzalez,
You are correct.
Thank you. 

Thank you for your help. :)
