To change the address, you need to login to your account at the Income Tax e-filing portal. Within your profile, you can change both the address as well as the bank account details. Once the changes are made, they will be updated on all income-tax related documents. Through your user account, you can also raise refund re-issue requests if you did not receive the TDS refund cheque and it was then returned to the IT department. You can find this request option in the ‘My Account’ section on the portal. You must also know that if someone else has collected TDS refund cheque in your name, then the department is no longer responsible for the refund amount.
