To claim your income tax refund this year, then apart from filing income tax return (ITR), you have to do one more additional step. This is because the process of claiming income tax refund has been tweaked a bit by the tax department.
From this year, you will have to make sure that you have pre-validated your bank account in which you wish to receive the income tax refund once your return is successfully filed.
Assessee can pre-validate through e-filing portal .
