Wrong head of sale

You can amend the GST returns for  FY 24-25 to reflect the correct classification of the sale as B2C. This involves filing a revised return. 

In GST, B2B transactions typically allow the recipient to claim input tax credit, whereas B2C transactions do not. 

The party mistakenly shown as a B2B recipient might have considered the GST paid as eligible for input tax credit. If the sale was actually B2C:

They might not be able to claim input tax credit.

You might need to address this with the recipient regarding any potential impact on their tax position. 

Steps to Take correct GST Returns: File a revised GST return for FY 24-25.

Communicate with the receipient : Inform the party about the correction and discuss any implications on their input tax credit claims.

If the FY 2024–25 invoice was reported as B2B in GSTR-1 and the recipient GSTIN was wrong, the correction route depends on the return period and the current portal facility. GSTR-1 amendments are generally time-barred after 30 November following the end of the financial year, or filing the annual return, whichever is earlier. For FY 2024–25, that date was 30 November 2025. If the correction is now time-barred, you generally cannot amend that invoice through GSTR-1; document the error and obtain advice on the appropriate accounting and recipient communication.

• If amendment is still permitted in your case, amend the invoice details in GSTR-1 to remove the incorrect GSTIN and report the supply as B2C, ensuring the tax liability and place-of-supply treatment remain correct. Do not issue a credit note and fresh invoice merely to change the buyer classification unless there is a genuine cancellation or change in the underlying transaction.
• The party whose GSTIN was wrongly reported may see the invoice in its GSTR-2B and could have claimed ITC. The recipient is not entitled to ITC on an invoice for a supply it did not receive; it should reverse any credit claimed, with applicable interest where required, and retain evidence of the correction. The actual buyer’s eligibility depends on the valid invoice and other ITC conditions.
• Confirm whether the wrong GSTIN was reported in GSTR-1 only or also on the tax invoice/e-invoice, and whether the actual buyer is registered. Those details affect the correction and documentation steps.

Correcting this type of buyer-classification error involves reconciling the invoice, GSTR-1, tax payment and the recipient’s ITC records.

B2B sale shown against a wrong GSTIN in FY 2024-25 – where things stand now:
• One correction to the first reply: GST has no "revised return". The only route was a GSTR-1 amendment (Table 9A), and for FY 2024-25 that closed on 30 Nov 2025 (Sec 37(3)). It cannot be done now.
• Since the tax was already paid with the correct rate and place of supply, no further tax is due. Keep an internal note, a corrected invoice copy and the buyer's confirmation on file. Disclose the true position in the GSTR-9 workings if the annual return is still being prepared or reconciled.
• If the wrong GSTIN was in another State, so IGST was paid instead of CGST+SGST (or vice versa), pay under the correct head and claim a refund of the wrong head under Sec 77 within two years. No interest applies.
• The party wrongly shown as buyer cannot keep the ITC, since it never received the goods (Sec 16(2)(b)). It should reverse the credit in GSTR-3B with interest u/s 50. Write to it formally, since a mismatch notice to it may lead back to you.
• Going forward, validate the buyer's GSTIN before invoicing, and correct errors in GSTR-1A or the next GSTR-1 well before 30 November.
