To cancel or change your transfer request, click into the account you are transferring from, you will see your scheduled transfers under “Scheduled and pending transactions”. Click the three dots on the right-hand side of the scheduled transfer, select “Edit” or “Delete”.
If you are trying cancel a transfer request on the scheduled date, you may modify the request any time before the cutoff time (4:00 PM EST). Once your request has been transmitted to ACH, you cannot cancel the transaction. If you missed the cutoff, your best option is to request a second transfer between the same two accounts sending the funds back to its point of origin (in effect, reversing your first transfer).
