Tax reporting becomes much easier when the underlying records have a clear trail. Each transaction should be understandable without relying on memory or a long message thread.
That trail usually includes the document, the date, the amount, the category, and the payment status. When something is unusual, add a short note while the context is still fresh.
Clarity is a form of control
The point of organized records is not only to submit a report. It is to help the business understand what happened, respond to questions, and make better decisions with the information it already has.
