Blocking of GSTR-1 Return for Non-Filing of GSTR-3B (Rule 59(6) SOP)

July 24, 202610 min readAkib Husain

Quick Summary: Why Is My GSTR-1 Blocked on the GST Portal?

Under Rule 59(6) of the CGST Rules, the GST portal automatically restricts GSTR-1 and IFF filing if you fail to submit your GSTR-3B for the preceding tax period (monthly or quarterly). To unblock GSTR-1, simply file the pending GSTR-3B return; the system automatically restores filing access within a few hours.

  • Legal Rule: Governed by Rule 59(6) of the CGST Rules, 2017.
  • Monthly Filers: Blocked if preceding month's GSTR-3B is un-filed.
  • Quarterly Filers (QRMP): Blocked if preceding quarter's GSTR-3B is un-filed.
  • DRC-01B Linkage: Unanswered DRC-01B notices (7-day window) also block GSTR-1.

1. Rule 59(6) Legal Mandate Explained

To prevent tax leakage and ensure suppliers deposit tax collected from buyers, the CBIC enforces Rule 59(6) of the CGST Rules.

Under Rule 59(6), a registered taxpayer is barred from furnishing outward sales supplies in GSTR-1 or using the Invoice Furnishing Facility (IFF) if they have failed to file Form GSTR-3B for the preceding tax period.

2. GSTR-1 Blocking Conditions for Monthly & QRMP Taxpayers

3. Step-by-Step SOP to Unblock GSTR-1

  1. Identify Pending Returns: Log in to www.gst.gov.in and check Return Dashboard to locate pending GSTR-3B periods.
  2. File Pending GSTR-3B: Calculate tax liability, pay net cash via PMT-06/Challan, and submit GSTR-3B with EVC or DSC.
  3. Automatic Restoration: The GST portal automatically runs background system checks and unblocks GSTR-1/IFF within 2 to 4 hours. No officer intervention is needed.
