Most S corporations use the calendar year, but other tax years are permitted. The due date is the 15th day of the third month following the end of the tax year. See the Instructions for Form 1120-S, U.S. Income Tax Return for an S Corporation.

The extended date if 7004 filed would be September 15.

Like @IRonMaN said E-Filed closed a week ago, so you will have to wait until E-Files opens in January ? (not announced yet)

Your client may not use a calender year, but if he does I hope you are talking about 2025
