Unfortunately, you can not change your bank
account information after you have filed your return unless it gets rejected; if
it is rejected, however, just log back in to your tax return and make any
necessary corrections.
If the
IRS has already accepted it, they will first try transmitting your refund to
the account you indicated on your return. Once the bank rejects it back to the IRS, they
will print a paper check and mail it to the mailing address you put on your tax
return. You can expect 6-8 weeks or
longer before you get your check.
If
the return hasn't already posted to the IRS system, you can ask them to cancel
the direct deposit and proceed directly to a paper check. You may call the IRS
toll-free at 1-800-829-1040, M - F,
7:00am – 7:00pm.
