CSAB 2026 Payment Failed – What to Do

Payment failures during CSAB choice-filling and seat acceptance are a fairly common source of stress for candidates, largely because these payments happen under strict deadlines and often during periods of very high portal traffic. Understanding the typical causes can help you avoid repeat failures and know exactly what to check when something goes wrong.

Before attempting the payment again after a failure, work through this checklist to avoid a duplicate deduction or repeating the same error.

• Check your bank SMS, email alert, or mobile banking app to see if the amount was actually deducted.
• Log back into the CSAB portal and check whether the fee status shows "paid," "pending," or "failed."
• If status shows "pending," wait — do not attempt a fresh payment while a transaction is still processing.
• If status clearly shows "failed" and no amount was deducted from your bank account, it is safe to retry.
• Switch to a different, more stable network connection if the previous attempt failed due to connectivity issues.
• Ensure your card/net banking daily transaction limit is sufficient for the fee amount before retrying.
• Try an alternate payment mode (e.g., switch from credit card to UPI or net banking) if repeated failures occur with the same method.

This is the most stressful scenario: your bank confirms the deduction, but the CSAB portal still shows the fee as unpaid. Here is the step-by-step resolution path typically recommended for this situation.
