More outward supply declared in 2020-21

This discussion addresses how to rectify errors in outward supply declarations made in GSTR1 and GSTR3B for the 2020-21 financial year. If you've declared more outward supply than actual or paid tax on a cancelled bill, the advice is to issue a credit note. This credit note should be reported in GSTR1 and the corresponding tax liability adjusted in GSTR3B. For GSTR9 filing, these adjustments can be reported in Table 12 to reflect the correct sales for the financial year. Crucially, credit notes must be issued before September 2021 to be applicable for the 2020-21 financial year adjustments.
