It is difficult to tell for sure, because you provided so little information. But normally, if your chart of accounts is set up to show Income accounts Less Expenses, the expense account balances will be positive numbers. This is a standard accounting convention. Everyone should know that the numbers are subtracted from income because of the the word “Less.”
So when an expense account balance is negative, that means it was entered as though it was income, but posted to an expense account. There are several ways this could happen. You might have used Receive Money
instead of Spend Money
to record the expense. Or, you might have entered the transaction as a negative number.
