This discussion addresses an issue where a user mistakenly left Table 6 blank when filing GSTR 4 for FY 2019-20. This has resulted in a negative liability showing in Table 8 of the FY 2020-21 GSTR 4, as tax was paid via CMP-08 but no output liability was registered. Participants are seeking advice on how to rectify this, with suggestions ranging from adjusting the liability in the current year's filing to waiting for the annual return, though concerns about potential assessment issues and incorrect filings are raised.
