The reconciliation section of a tax return allows the accounting income to be reconciled to the taxable income. The reason for this is that certain income items may not be assessable or the amounts may differ. Similarly, with expenses, some accounting amounts may not be deductible or amounts may differ.

As per ATO rules if it's SBE, 6X must be equal to sum of item 10 A+B and there is no need for reconciliation.
