For GST portal or app-related issues, here is a comprehensive troubleshooting guide:
1. GST Portal (gst.gov.in) Common Issues and Solutions:
a) Login Issues: Clear browser cache and cookies → Use Google Chrome (latest version) in Incognito mode → Disable browser extensions → Use a laptop/desktop (avoid mobile browser for filing)
b) OTP Not Received: Check if mobile number linked to GST login is correct → Update mobile number via Core Amendment if needed → Try 'Resend OTP' after 2 minutes
c) Form Not Submitting: Check all mandatory fields are filled → File size of attachments within limit (usually 5MB PDF/JPEG) → Try at non-peak hours (late night/early morning when server load is lower)
d) ITC Auto-Population Issues: GSTR-2B data is generated on 14th of each month — wait until then for ITC to appear → If supplier has not filed GSTR-1, their invoices won't appear in your 2B
2. GST Mobile App (GST India): The official GST app (available on Play Store/App Store) is primarily for checking GSTIN details, filing nil returns, and tracking refund status — major compliance work (GSTR-1, 3B) must be done on the web portal.
3. Helpdesk: GST helpdesk number: (toll-free). Raise ticket on GST portal → Help → Grievance/Complaint for portal-specific technical issues.
4. Third-Party GSP/ASP: For high-volume filers, use GST Suvidha Providers (like ClearTax, Tally, GSTN-certified ASPs) which have better stability than direct portal filing.
