Sometimes it can take a few days for the payment to be processed so no need to panic quite yet.

Call the phone number on the 8879 and see if its scheduled.

Half a dozen questions about this every year, which gives @IRonMaN purpose to his life.  But this is the first year after IRS and Treasury got rid of much of the experienced IT staff, and demotivated the rest.  

I don't like to do the payment from the software but a handful of my clients insist on it.  Several years ago, a new client at the time insisted on going that route.  For the first two or three years I would get a phone call from him because it didn't clear on 4/15.  Then another call because it didn't clear on 4/16 ------etc, etc.  It took awhile for him to get the hang of the idea there can be some delays.  But that's why I don't like going that route ------ their problem becomes my problem.  

I have been getting the same question over and over as well yesterday and today.  I have responded to each email and text with a four word answer:

Patience is a virtue.

@IRonMaN are we going to have to do direct debit payments next year for everyone?

No more checks after 9/30/25 to or from US Treasury, with limited exceptions, per the current Executive Order.

Clients can use IRS Direct Pay instead of us doing direct debit.
