Generally, once your return is accepted, information pertaining to your payment, such as bank account information, payment date, or amount, cannot be changed.
If changes are needed, your only option is to attempt to cancel the payment. To proceed, you should wait at least 7 to 10 days after the return has been accepted to contact IRS e-file Payment Services 24/7 at 888-353-4537 to inquire about or cancel your payment.
Cancellation requests MUST be received no later than 11:59 pm ET (Eastern Time) two business days prior to the scheduled payment date.
What happens if the payment cannot be processed by the IRS?
If a payment is returned by your financial institution (i.e. due to insufficient funds, incorrect account information, closed account, etc.) the IRS will send a Letter 4870 to the mailing address listed on the return.
The letter will provide an explanation of why the payment could not be processed and provide alternative payment options to resolve any outstanding balance owed.
If this does happen, it is your sole responsibility to make other payment arrangements to prevent you from incurring any additional applicable penalties or interest.
Additionally, you should contact your financial institution if there is any error with the amount withdrawn or if funds are released prior to the date specified in your electronic payment request to obtain any additional information.
