I have not received my tax refund. What should I do?

Please make sure your return has been either e-verified or you have posted a signed acknowledgment of ITR-V to CPC Bangalore after filing it and you have received back on email, a Receipt/Confirmation from CPC Bengaluru for the same . The Refund is issued once the Return is processed by CPC Bengaluru and you have no old Tax dues/demands in Income Tax Department records. Please make sure that the return contains your correct bank account number and other details as well, since the refund will be directly deposited in your Bank Account.

In case all the above check points are covered and even then the Tax Refund is not received, you are suggested to check the Income Tax Refund Status on the following website:
