If you owe taxes to the IRS, you can pay either using Electronic Funds Withdrawal (EFW) or Electronic Federal Tax Payment System (EFTPS).
For EFW, provide bank details and choose a Payment Requested Date that is within five days from the transmission date. You must maintain sufficient funds in your account.
For EFTPS, it's your responsibility to log in to the EFTPS website and schedule your payment to the IRS at least one day before the form due date.
