Explain Your Tax Return to Yourself Before Filing

You are staring at a section of your self-assessment return and you are not entirely sure what it wants from you. The HMRC guidance is written in official language and explains very little. A wrong guess wastes time, sometimes money. This explains the section in plain English and tells you what a person in your situation would normally put.
