CMN.ATO.IITR.EM0070 appears at lodgment when the interest income at Item 10 is less than the ATO’s prefill data. This error doesn’t show during pre-lodgment checks. If the amount has been changed, you must complete the Interest Adjustment Reason Code and Description fields to explain the difference. This ensures the ATO understands why the reported amount doesn’t match their records.
Refer to the ATO website for full details of the official resolution.
