NON-TRANSMISSION OF INVOICES DUE TO NEGATIVE BALANCE

Hey Asif, thanks for sharing your issue. Here’s what’s likely happening and how you can address it:

You made a supply to Nepal (a zero-rated export) with tax payment (IGST ₹810).
In GSTR-3B, you incorrectly showed this supply under outward taxable supplies (taxable domestic sales) instead of the zero-rated supply column.
In GSTR-1, you correctly declared it as export (zero-rated) with payment of tax.
Because of this mismatch, ICEGATE shows a negative ITC balance from 2017 till now.

Export sales with payment of IGST should be declared as zero-rated supplies in both GSTR-1 and GSTR-3B.
Declaring export supplies as taxable domestic outward supplies in GSTR-3B leads to mismatch and negative balance issues.
ICEGATE reconciles your GST returns with customs data, so inconsistency leads to negative ITC or tax liability issues.

File Revised Returns (if possible):
If your GST portal allows, file amended GSTR-3B returns for the affected periods correctly showing the supply as zero-rated outward supply with IGST paid.
- This might be limited by the time window for amendments (usually until due date of filing annual return).
File a Letter of Explanation to GST Authorities:
If amendments are not possible due to time expiry, send a letter explaining the error and requesting rectification.
Adjust Future Returns:
For current and future GST returns, ensure exports with IGST payment are properly reported in the zero-rated supply column in both GSTR-1 and GSTR-3B.
Consult a GST Practitioner or Chartered Accountant:
Given this is a historical issue since 2017, professional help can guide you on the best legal way (maybe using TRAN-1/TRAN-2 forms or filing refund claims) to resolve the negative balance.

Keep all export documents handy (shipping bills, payment proofs, invoice copies).
Check your GST portal for credit ledger and liability ledger mismatches.
Inform your customs broker or ICEGATE helpdesk if required.
