I am using the BAS to pay GST to the ATO on a quarterly basis. I have paid the tax to end of March based on the BAS but subsequently found that some invoices were wrongly coded for GST and corrected these in April. Manager has now adjusted the March BAS but has not adjusted the June BAS. I now have this current BAS which does not reflect what I am actually due to pay the ATO.
Is there a way to force the corrections onto the June BAS?
It would be better that the existing BAS statements were not changed by the program and that all corrections were automatically carried over to the current BAS.
The correct way is to send the amended prior BAS statement to the ATO, then pay/receive the difference.
For small amounts corrected early the ATO may not get upset if the total is accurate and you make the correction in the next BAS payment (carry through the corrections to the ATO, then in Manager split the payment to the current quarter and a correction to the prior quarter). Please note I do not speak for the ATO so they may not approve this correction method as they may want to charge interest on the late payment.
