Vide Notification No. 78/2020 – Central Tax dated 15th October 2020, it is mandatory for the taxpayers to report minimum 4 digits or 6 digits of HSN Code in table-12 of GSTR-1 on the basis of Aggregate Annual Turnover (AATO) in the preceding Financial Year. To facilitate the taxpayers, these changes are being implemented in a phase-wise manner on GST Portal wherein Phase 2 was implemented on GST Portal effective from 01st November 2022.
In continuation of the phase wise implementation, Phase-3 of reporting of HSN codes in Table 12 of GSTR-1 & 1A is being implemented from May 2025 return period. The changes implemented are detailed in the table below.

| Phase 3 |
i. Manual user entry of HSN will not be allowed. ii. HSN code can be selected from drop down only. iii. A customized description mentioned in HSN master will auto-populate in a new filed called “Description as per HSN Code”. |
|
| Phase 3 |
In Table-12 validation with regards to value of the supplies have also been introduced. i. These validations will validate the value of B2B supplies shown in different Tables viz: 4A, 4B, 6B, 6C, 8 (recipient registered), 9A, 9B (registered), 9C (registered), 15 (recipient registered), 15A (recipient registered) with the value of B2B supplies shown in table-12. ii. Similarly, validations will validate the value of B2C supplies shown in different tables viz: 5A, 6A, 7A, 7B, 8 (recipient unregistered), 9A (export), 9A (B2CL), 9B (unregistered), 9C (unregistered), 10, 15 (recipient unregistered), 15A (recipient unregistered) with the value of B2C supplies shown in Table-12. iii. In case of amendments, only the differential value will be taken for the purpose of validation.
*However, initially these validations have been kept in warning mode only, that means warning or alert message shall be shown in case of mismatch in values, whereas taxpayers will be able to file GSTR-1 in such cases. Further, in case B2B supplies are reported in other tables of GSTR-1, in that case B2B tab of Table-12 cannot be left empty. |

3. Apart from above, the following additional enhancement have been made in Table-12 of GSTR1/1A:
i. Table 12 of GSTR-1/1A is now bifurcated into two tabs, namely, “B2B Supplies” & “B2C Supplies”. Taxpayers need to enter HSN summary details of B2B Supplies and B2C Supplies separately under respective tab.
ii. A new button has been introduced in Table 12, “Download HSN Codes List”. Upon clicking of this button, taxpayer would be able to download an excel file with the updated list of HSN & SAC codes for goods and services along with their description.
iii. The button for “Product Name as in My Master” has now been made searchable. Taxpayer can search the description provided by them in My HSN Master and upon selection of the same, the HSN code, Description as per HSN Code, UQC & Quantity shall be auto-populated. This is an optional functionality.
Reporting in Table 13 of GSTR-1/1A
In Table 13 of GSTR 1/1A, which requires taxpayers to provide details of documents issued, is now mandatory from May 2025 return period. Taxpayers will no longer be able to leave this table blank and proceed with filing their return. If B2B or B2C supplies are reported in any table of GSTR-1 or GSTR-1A, an error message will appear if Table 13 has not been filled.
