Please see the below information on how to change your direct deposit information.
If you have not already filed the return, then after you have completed and reviewed your return(s) you select the "File" option from your Dashboard screen. You will be presented with three choices . The second choice "Choose Your Refund Method" is the area where you will enter your current bank account information.
If you have filed the return, please review the below information.
If you e-filed, wait until your return is accepted or rejected by government.
What if the account information I entered is valid, but for somebody else's account?
The good news is that most banks have systems in place that prevents checks from being deposited into accounts bearing a different name.
Even so, it would be good idea to call the IRS at 800-829-1040 as soon as you realize your mistake. Also notify your state tax agency if you're getting your state refund direct-deposited.
