If you have not
already filed and submitted your tax return follow the steps below to change the way you receive your refund:
1. Sign into your
account, click take me to my return
2. Click the File heading
3. Follow the prompts
for Step 1. When you get to Step 2, this is where you can change your information. Follow the prompts to edit.
If you have already
filed and submitted your tax return you are unable to edit the bank account
information once the return has been accepted. If your return has been filed
and submitted and rejected then you are able to change the information, just
follow the steps above.
If the IRS is unable
to deposit your refund into your account, they will mail you a refund
check.
