GSTN Issues Advisory On Implementation of Mandatory Mentioning of HSN codes in GSTR-1 & GSTR-1A



Quick Summary
The GST Network (GSTN) has issued an advisory regarding the implementation of Phase-III for reporting HSN codes in Table 12 of GSTR-1 and GSTR-1A, effective from the January 2025 return period. This phase replaces manual HSN entry with a dropdown selection and bifurcates Table 12 into B2B and B2C supplies tabs. New validations for supply and tax amounts have also been introduced, though they will initially be in warning mode.

After successful implementation of Phase-I & Phase-II now Phase-III regarding Table 12 of GSTR-1 & 1A is being implemented, from return period January 2025. In this phase manual entry of HSN has been replaced by choosing correct HSN from given Drop down. Also, Table-12 has been bifurcated into two tabs namely B2B and B2C, to report these supplies separately. Further, validation regarding values of the supplies and tax amounts involved in the same, have also been introduced for both the tabs of Table-12. However, in the initial period these validations have been kept in warning mode only, which means failing the validation will not be a blocker for filling of GSTR-1& 1A.
