GST Excess Payment in March 2020
I found in November 2020 that, inadvertently put Tax on outward supply in GSTR-3B of March 2020, excess i.e. CGST 325500 and SGST 325500. Accordingly ITC adjusted.
1) To rectify the mistake can I reduce the tax on outward supply from November onwards in GSTR-3B. Note that GSTR-3B have already uploaded up to October 2020
2) If possible, then in GSTR-9, FY 2020-2021, where to adjust this reduced Outward tax liability?
Please give me a solution.
