For net income on the balance sheet to be the same as the P&L:

- The P&L must be run from the beginning date of the fiscal year of the Balance sheet to the date of the Balance Sheet. Both could be run with the date range, "This Fiscal Year-to-Date", for example.

- Both the P&L and the Balance Sheet must be on the same 'basis' - cash or accrual.

If you try that, then does it work as expected?
