However, because ITR filing is a once-a-year procedure, it is possible that you have changed your bank account number.
For smooth tax filing, it's critical that a taxpayer adds a new bank account number.
If you want to update the Bank Account Number for a refund failure case, go to 'My Account' 'Refund reissue request' on the Income Tax e-Filing website.
Choose between ECS and Cheque as the method for receiving your return.
Fill in the new Bank Account Number and your address information. Send in your request.
Your new address is updated with the Income Tax Department once the request is submitted.
