I am busy trying to understand how to fill in my tax returns for a partnership. I am aiming to put the correct data in the correct boxes but am currently wondering what the difference is between the cost of sales (5) and the purchases and other costs (39). They sound a lot like the same thing, as in the cost of sales requires purchases. If someone could help me out here I would be greatly appreciative, and if they could explain it in relation to how this fits in with me attempting to make some money during a lull in employment by taking stock photography this would further aid my understanding
Hi @Theythem
Not necessarily. Item 5 is where all the income and expenses are itemised and detailed. Item 39 is the total value of all trading stock on hand excluding certain items.
There's so many circumstances which could mean these items can be two different numbers. Item 39 can even be a zero.
