After you file

How long does it take for the IRS to process a credit card payment?
 
Your payment is processed immediately—at least by the next business day—and the payment date is to the date the payment is authorized. While the payment is processed almost immediately, it can still take five to seven days for the IRS to post the payment to your tax account.
 
 
Also, see the following:
 

When will my tax payment go through?

During non-peak times, funds are usually withdrawn on the payment date you specify, assuming your e-filed return has already been accepted (received) by the IRS.

 

If that date happens to fall on a weekend or federal holiday, the funds are typically withdrawn the next business day.

 

Now, if you filed right before (or on) the busy April 18 deadline, the IRS may not be able to debit your payment until after the deadline, due to high e-filing volume. In addition, it can take your bank another few days to post the debit to your account.

 

No worries; as long as you filed your return or extension on or before April 18 and you selected April 18 (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 or contact your state tax agency, as appropriate.
