Translate a Complicated Tax Return Section Into What You Need to Fill In

You are completing your self-assessment tax return and the section is asking you something that the guidance note does not clearly explain. This translates it: what the question is actually asking for, where the figure comes from, whether you need to fill it in at all, and what people typically get wrong in this section. Then gives you the answer in one instruction.

You are completing a UK self-assessment tax return and a particular section is unclear: the question seems to ask for something specific but the guidance note does not help. Translate the section below into what you are actually being asked to provide, what the relevant figures are and where to find them, and whether you need to complete this section at all. If common sources of error apply to this section, name them. End with a single instruction: what to put in the box and where the number comes from.
