There is a circular to handle negative amount in GSTR-3b. Refer circular # Circular No. 26/26/2017-GST, Dt.29/12/17 (4). Where it is clearly mentioned that if we have sale return in a month is more than sales, we will file the GSTR-1 in normal way. But will not show this negative amount in GSTR-3B for that month. By doing so we will end up paying more tax for that month. In subsequent month(s) we will show less amount by this differential amount in GSTR-3B compared to GSTR-1 of that month and will pay less. Though there is no option to setup this in the portal, the cumulative balance of GST liability in the ledger will get nullified.
Adjust Sales Return in GSTR 1 for the month of Nov 2019 and adjust 3B in subsequent month GSTR 3B .
