The 4th installment of IL-1120-ST-V is due the 15th day of the 12th month, yet ProSeries shows the due date as 01/16/24.  We have consulted with IL Dept of Revenue regarding this and they have confirmed that December is the due date, not January.

Also, why can't I check a box on the estimated tax payment schedule that says the client is going to pay the estimated tax payments electronically?  When I check the box on the info sheet that says the client is enrolled in electronic payments, it only flows through to the current year tax due and eliminates the voucher for that.  This makes the client letter very confusing and it prints the estimated tax vouchers even when you don't want them to print.  Any ideas?
