Since the return framework in GST system is predominantly transaction based, any changes required to be done at any stage shall also have to be done at the transaction level rather than at the aggregate level of return. Therefore, in GST system, no revision of returns is allowed.
If taxpayers find that there is an error in the invoices uploaded by them, they can correct the details of invoices in the return of the month when they were noticed, by providing necessary details in tables meant for amendment of details already furnished in statements of outward and inward supplies. In case the invoices were wrongly uploaded, it is presumed that they would not have got matched and the ITC on such invoice would not have been claimed. This system allows such invoices to be corrected through amendment tables. However, in case of matched invoices, the corrections shall have to be done through credit/debit notes.
All unreported invoices of previous tax period would be reflected in the return for the month in which they are proposed to be included. The interest, if applicable will be auto populated.
All under-reported invoices and ITC revision that have been matched, will have to be corrected using credit/debit note and such credit/debit note would be reflected in the return for the month in which such adjustment is carried out. The credit/debit note will have provision to record original invoice, date etc. to enable the system to link the same with the original invoice as also to calculate the interest, if applicable. Its format will be similar to that of invoice.
There would be separate tables in the returns for reflecting those adjustments for which credit/debit notes are not required to be issued/ issued. The interest, if applicable will be auto populated.
