GST Portal Glitch (April 2026): Missing Invoices in GSTR-2B Explained
In mid-April 2026, taxpayers across India reported a critical mismatch on the Goods and Services Tax Network (GSTN) portal. The issue affected the visibility of certain March 2026 invoices, creating confusion around Input Tax Credit (ITC) claims.
This blog provides a clear, concise, and up-to-date explanation of the issue, its impact, and the practical steps businesses should take.
What Was the Issue?
A technical glitch caused some invoices filed by suppliers in GSTR-1—particularly on April 8, 2026 to:
- Appear in the Invoice Management System (IMS)
- Not appear in GSTR-2B (auto-drafted ITC statement)
- Incorrectly show a “Non-Filed” status in IMS
This created a mismatch between available invoice data and the ITC reflected for taxpayers.
Why This Matters
1. Impact on Input Tax Credit (ITC)
GSTR-2B is the primary document businesses rely on to claim ITC in GSTR-3B. When invoices are missing:
- ITC may be under-reported
- Businesses may pay excess tax in cash
- Working capital is unnecessarily blocked
2. IMS vs GSTR-2B Confusion
The issue highlighted a key inconsistency:
- IMS showed invoices as available (indicating supplier upload)
- GSTR-2B did not reflect those invoices
- “Non-Filed” status appeared despite successful filing
This made it difficult for taxpayers to rely solely on system-generated data.
Who Was Affected?
The issue primarily impacted:
- Businesses whose suppliers filed GSTR-1 on or near April 8, 2026
- Taxpayers who depend entirely on GSTR-2B without cross-verification
Likely Cause
While no detailed technical report has been released, the issue appears to stem from:
- Data processing delays between GSTR-1, IMS, and GSTR-2B
- Cut-off timing mismatches
- Status flag errors showing incorrect “Non-Filed” indicators
Latest Status (as of April 16, 2026)
- GSTN has advised users to raise tickets for unresolved discrepancies
- Many taxpayers confirmed that re-downloading GSTR-2B on April 16 showed previously missing invoices
- The issue appears to be gradually resolving, though not uniformly for all users
Risks If Ignored
Failing to address this issue may lead to:
- Under-claiming of ITC
- Increased tax liability
- Cash flow strain
- Future reconciliation challenges and notices
Recommended Actions
1. Do Not Rely Solely on GSTR-2B
Cross-check with:
- IMS data
- Purchase registers
- Supplier invoices
2. Re-download GSTR-2B
Before filing GSTR-3B:
- Download the latest version
- Verify if missing invoices have been updated
3. Use IMS Carefully
Even if invoices show “Non-Filed”:
- Check their availability status
- Validate with supplier records
4. Communicate with Suppliers
Confirm:
- GSTR-1 filing date
- Invoice upload status
5. Raise GSTN Ticket if Required
If discrepancies persist:
- Use the GST portal grievance system
- Attach invoice details and IMS screenshots
Conclusion
The GST portal glitch in April 2026 highlights an important lesson: system-generated reports like GSTR-2B, while useful, should not be the sole basis for ITC claims—especially during known technical disruptions.
With the issue now partially resolved, taxpayers must take a cautious and proactive approach. Reconciliation across IMS, supplier data, and updated GSTR-2B is essential to ensure accurate ITC claims and avoid unnecessary financial impact.
Staying alert and verifying data before filing returns will help businesses navigate such system inconsistencies effectively.
