Executive Regulatory Summary

The GST portal automatically triggers system-generated notices under Rule 88C (Form DRC-01B) when tax liability in GSTR-1 exceeds GSTR-3B by specified thresholds, and under Rule 88D (Form DRC-01C) when ITC claimed in 3B exceeds GSTR-2B. Step-by-step resolution protocol within the mandatory 7-day window to avoid GSTR-1 blockage.

Key Statutory Takeaways

Mandatory 7-day response window: taxpayer must either pay the differential tax with interest or file an electronic explanation.
Failure to respond blocks subsequent period Form GSTR-1 / IFF filing automatically.
DRC-01B targets outward tax differences; DRC-01C targets excess Input Tax Credit claims.
Legitimate grounds include subsequent invoice amendments, advance adjustments, or timing differences.

Actionable Compliance Checklist for Businesses

Step-by-step advisory measures prescribed by ASGR and CO for immediate adherence:

1Monitor portal communications daily for automated DRC-01B and DRC-01C intimations.

2Analyze whether variance is due to clerical errors, credit notes, or legitimate timing discrepancies.

3If tax is genuinely due, remit via Part B of DRC-03 and input ARN in the DRC response tab.

4If disputed, select valid drop-down explanation and upload concise reconciliations within seven days.
