Get My Payment cannot update direct deposit bank account information after an Economic Impact Payment has been scheduled for delivery. To help protect against potential fraud, the tool also does not allow people to change direct deposit bank account information already on file with the IRS. However, people who did not use direct deposit on their last tax return to receive a refund, or when their direct deposit information was inaccurate and resulted in a refund check, will be able to provide that information and speed their payment with a deposit into their bank account.
