I failed to enter two expense entries of which 1 should have been reported in Q1 and the other in Q3. I need to make an adjustment in Q4 to include these entries as adjustments in Q4 and claim GST on them.
The adjustment is to show under “G18 Adjustments” of the BAS worksheet. Are there any guides showing how to make these adjustments? If not does anyone know how to enter / record these adjustments?
This is not supported - mostly because adjustments are used for something else (not for fixing mistakes).
To fix mistake, you should either correct the original entry and lodge amended BAS or make a journal entry with current date where you credit expense without tax code and debit the same expense with tax code.
