Keyphrase Highlight: GST filing rules change
Let’s understand how this GST filing rules change will affect day-to-day compliance.
New Filing Restrictions & Penalty Triggers
CBIC has tightened sequential filing rules:
- No GSTR-1 unless GSTR-3B filed for previous month
- Late GSTR-3B will block future return filing
- Interest & late fees auto-calculated based on actual delay
Legal Source: Rule 59(6) of CGST Rules updated via Notification No. 07/2025-CT dated 25.06.2025.
ITC Matching with GSTR-2B Becomes Mandatory
You can only claim ITC shown in your GSTR-2B, even if your supplier has uploaded invoices later.
- Mismatched invoices? ITC will be disallowed.
- Supplier compliance directly impacts your cash flow.
Expert Tip:
Ask vendors to file GSTR-1 by 11th of each month to ensure timely ITC reflection in GSTR-2B.
Auto-Populated GSTR-3B: Less Manual Entry
Starting July, GSTR-3B will auto-fill:
- Output tax liability from GSTR-1
- ITC from GSTR-2B
- Reverse charge & interest columns
Benefit:
Faster filing but manual override now risky, as discrepancies may trigger scrutiny.
