Declaring income from a shared business

Good morning, I hoped to clarify a shared business situation and how the income would be taxed. I currently run a YouTube and Patreon with 2 friends, the way these sites work is they payout out to a single account (Mine) and then I distribute everyone's third to their respective account. For them, the situation is quite easy as they receive the money and then can file it under their own self-assessment tax. For myself, I already file under self-assessment so adding these figures to my total is not a problem. My concern however is when I declare the numbers on my self-assessment these numbers will only be 1/3 of what I received from YouTube and Patreon in my bank account. Will this likely be an issue when declaring my self-assessment that I should clarify somewhere? Is there a way I can more formally represent this relationship to avoid any issues? Was struggling to find any information on this specific type of arrangement so any guidance would be really appreciated

Hi,

As the income is paid to you, you declare all of it and then deduct the other two thirds as wages or expenses.

Thank you.
