GST Check by Bank: Why It Happens

The GST portal primarily performs bank account validation, not the other way around.

2026 Clarification:

• The GST system verifies your bank account using PAN, GSTIN, and banking network data.

This validation ensures that refunds and financial transactions are processed only to verified accounts.

Why Adding Your Bank Account in GST Portal Matters

• Without a validated bank account, GST refunds may fail or get delayed
• As per Rule 10A of CGST Rules, bank details must be added within 45 days of registration
• 2026 Update: Non-compliance may lead to:
• Suspension notices
• Restriction on return filing
• GST now uses automated validation systems to prevent fraud and incorrect claims

Adding and validating your bank account ensures smooth compliance and uninterrupted GST activities.
