To resolve CMN.ATO.IITR.410014:
Log in to HandiTax and select your Individual tax return.
Double-click on the Main form I.
Navigate to Item P8 Label A and check if a Business loss activity number is present.
If Label A has a value, then Label G – Type of loss must be set to 5.
Update Label G to 5 if needed to match ATO requirements.
This ensures the return passes validation for loss type references.
