What if the due date is on a weekend or a legal holiday?
Regardless of which payment method you choose, if a tax due date falls on a weekend or a legal holiday, the Timely Filed Date becomes the next state business day. If you are using the ACH Debit option, you must complete your call no later than 5:00 p.m. Central Time on the timely filed date, and indicate your Scheduled Payment Date to be the following day.
