Setting up partnership for a jointly owned stock/forex trading account

Hi Officer My wife and myself are both sole traders providing different goods/ services to clients. At the beginning of financial year 24/25, we started to do regular forex trading for an extra source of income. We have the following questions regarding the above development: 1. The brokerage account is a joint account owned by my wife and myself. Should we register for a partnership or we simply split the income/ loss and add a new trade in our existing self-assessment? 2. The brokerage account was previously used for occasional trading use of long term investment. We only began our regular trading habit in April 2024, we wonder if we have to register for the partnership, is it ok if we regard such date as the date when we start our partnership business? Thank you very much.

Hi,
This is separate to your sole trading businesses.  
The gains / losses should be split 50/50.  
There is no requirement to register as a Self assessment partnership, unless you are setting this up as a partnership business.
Thank you.
