My state taxes have been paid, but not my federal taxes, I’d like to know why?

If you are referring to an automatic tax payment from your bank account, don't be concerned - the IRS will process your payment as quickly as they are able.

You really can't find out when the IRS is going to debit your bank account for a tax payment - they don't provide that information.  

The IRS cannot debit your bank account any earlier than you authorized when filing, but they can wait as long as they want after that date.

Presently, they are way behind in processing returns and issuing refunds because of ongoing changes in the tax code. It is reasonable to believe the same delays are occurring in payment processing.
