Totals in the Response Summary are returned from the ATO and are not generated by the software.
If you submit a batch the Gross Payment and PAYG withheld will report the totals on the Response Summary.
Current Year Update
If you do a Current Year Update submission first, meaning you have not previously submitted batches the Gross Payment and PAYG withheld will report the total amounts.
If you do a Current Year update submission after doing batch submission the Gross Payment and PAYG withheld will report $0. This may be the case if you have had issues with your batch submissions and are doing a Current Year Update submission.
Full Year Submit
The Full Year Submit will report the Gross Payments and PAYG withheld on the Response Summary.
