You've described a common issue under the GST Composition Scheme — filing CMP-08 with output tax liability shown but without mentioning the corresponding CGST/SGST amounts, even though you've already paid the correct amount via challan, and the amount reflects in your Electronic Cash Ledger.
Since CMP-08 cannot be revised, here’s how you can handle this and adjust it in your Annual Return (Form GSTR-4).
🔧 Issue Summary:
- ✅ CMP-08 for Q4 (Jan–Mar 2025) filed on time.
- ❌ CGST/SGST liability fields left blank.
- ✅ Challan created & payment made correctly (amount visible in cash ledger).
- ❓ Now you're filing Annual Return (GSTR-4) and want to adjust/declare the payment properly.
✅ Solution:
1. No Option to Revise CMP-08
You're correct — CMP-08 once filed cannot be revised. However, this does not result in loss, since your tax has already been paid and is available in the cash ledger.
2. Adjustment via GSTR-4 (Annual Return)
In GSTR-4, you're required to declare total turnover and tax liability for the year. Here’s how to manage your issue:
- In Table 6: Tax Rate-wise details, mention the correct taxable turnover and tax liability (CGST & SGST) for the full year, including Q4.
- Your previously paid challan amount (sitting in the electronic cash ledger) will automatically get adjusted when you offset the liability in GSTR-4.
3. Steps to Follow:
- File GSTR-4 with correct figures – Include the correct CGST/SGST liability for the Jan–March quarter.
- Offset the liability using the available balance in the cash ledger (from the earlier paid challan).
- No penalty is applicable, as the payment was made on time and only a reporting mistake happened.
📌 Important Notes:
- Keep records of the paid challan and a copy of CMP-08 for your files.
- If any notice is received from the department (which is rare for such mistakes), you can provide proof of payment and explanation.
- Make sure future CMP-08 filings include both liability and payment to avoid mismatch.
✅ Conclusion:
You do not need to worry — just declare the correct tax liability in GSTR-4 and use the existing cash ledger balance to offset the tax. There’s no loss of money or legal issue here, since the tax was paid properly.
