Within my Expenses Tab - I have 'Everything Else' with a large negative number. Its left my overall Expenses as -£9 which is certainly incorrect. Does anyone know what might have happened?

Hello there, kotechfilms.

A negative expense would indicate an income. We can drill down to the transactions in the Everything Else section of your QuickBooks Self-Employed account. This way, you'll be able to see if they are correctly categorized. Categorizing your transactions can also help us if the estimated taxes are accurate.
