Yes , it is common due to high e-filing volume it can take a little while longer to process the payment and then it can take your bank another few days to post the debit to your account.
During non-peak times, funds are usually withdrawn on the payment date you specify, assuming your e-filed return has already been accepted (received) by the IRS.
Now, if you filed right before (or on) the busy April 18, 2017 deadline, the IRS may not be able to debit your payment until after the deadline.
No worries; as long as you filed your return or extension on or before April 18, 2017 and you selected April 18, 2017 (or earlier) as your payment date, you won't get penalized for late payment.
In the meantime, keep an eye on your bank account – if you still don't see the debit 7-10 days after your return has been accepted, call IRS e-file Payment Services at 1-888-353-4537 to verify the scheduled payment date..
