GST QUERY REGARDING B2B

This discussion addresses a Goods and Services Tax (GST) query concerning a B2B invoice from the financial year 2019-20 that was mistakenly entered into GSTR1 for the financial year 2020-21. The advice provided is to consider the invoice for FY 2019-20 as that's when the booking entry was made. If the invoice was declared in GSTR1 for FY 2020-21 up to September, it should be reported in Table 10 of the GSTR9 for FY 2019-20.
