While filing GSTR-1, HSN code wise details are submitted. Now, while filing annual return, we came to know that we had selected wrong HSN in GSTR-1. What are the consequences and what need to be done in filing Annual Return. Can this mistake be corrected or can we feed correct HSN in annual return. If we feed correct HSN in annual return then there will be mismatch in GSTR-1 and GSTR-9 data. Please suggest

Reply—It is optional to declare HSN code while filing annual return for financial year 2019-20 (Refer notification no.79/2020 (central tax) dated 15.10.2020). Taxpayer can declare correct HSN code while filing annual return, mismatch in HSN code can be explanied at later stage.
