Important: A DRC-01B intimation should not be ignored. It generally means that the tax liability declared in GSTR-1 or IFF is higher than the liability reported and paid through GSTR-3B.
The GST system compares the sales liability reported in GSTR-1 with the tax liability reported in GSTR-3B. Where the difference exceeds the system’s prescribed limit, an electronic intimation may be issued in Form GST DRC-01B Part A.
The taxpayer must check the difference and either pay the applicable amount with interest or submit a valid explanation through DRC-01B Part B.
Why can a DRC-01B mismatch arise?
An invoice or credit note may have been entered incorrectly in GSTR-1.
IGST, CGST or SGST may have been reported under an incorrect tax head.
The liability may have been reported or adjusted in a different return period.
Sales liability may have been missed or reduced while filing GSTR-3B.
What should you do after receiving DRC-01B?
Login and go to Services, Returns and Return Compliance. Open the Liability Mismatch DRC-01B section.
Compare invoices, debit notes, credit notes, amendments, tax heads and return-period adjustments.
If tax is genuinely short-paid, calculate the tax and applicable interest before making payment through DRC-03.
Mention the DRC-03 ARN where payment is made, provide the reason for the difference, or provide both where required.
Do not give a general reply
Your explanation should match the GST returns and supporting records. Keep invoice-level reconciliation, ledgers, credit notes, payment details and earlier-period adjustments ready.
What can happen if you do not respond?
- The unpaid difference may become recoverable under the GST law.
- Filing of a later GSTR-1 or IFF may be restricted until the pending compliance is completed.
- Interest exposure may continue where tax was genuinely short-paid.
- A weak or unsupported reply may lead to further departmental action.
Simple example
| Particulars | Amount |
|---|---|
| Tax liability reported in GSTR-1 | ₹2,40,000 |
| Tax liability reported in GSTR-3B | ₹2,00,000 |
| Difference requiring verification | ₹40,000 |
The difference of ₹40,000 should first be reconciled. If it represents genuine short payment, the taxpayer may need to pay it with applicable interest. If the difference is due to a valid reporting or timing reason, a clear explanation with supporting documents should be submitted.
