Tables
| Tab | What it contains |
|---|---|
| 4A, 4B, 4C, 6B, 6C - B2B | Invoices to registered customers: GSTIN, receiver name, invoice, date, POS, rate, taxable, tax, invoice value |

Before you file
- Check that every B2B invoice shows a GSTIN and a place of supply.
- Tally the totals with the Sales Register and Credit Note Register for the same month.
- Check the HSN Summary: the number of digits must match your turnover (4 digits up to ₹5 crore, 6 above).
- Click EXPORT CSV to prepare the upload, or PRINT for your file.
Due dates
Monthly filers: the 11th of the next month. Quarterly (QRMP) filers: the 13th of the month after the quarter, with invoices optionally uploaded monthly through IFF.
Found a mistake after filing? Do not edit the invoice. Report the correction in the next GSTR-1 (amendment tables) or through GSTR-1A, and issue a credit or debit note where the value changed.
