If
you have filed your return and it is in pending status, wait until it's either
accepted or rejected. If it has been accepted, it's too late to change your
bank account information. If it happens to get rejected, you
can update your bank account before re-submitting your return as well as
update the issue that caused the rejection.
If
the information you provided is for a closed or invalid bank account, or if
your bank rejects your direct deposit, the IRS will mail you a check.
