To the students in a class:

1) Assignments submitted later than tomorrow will not be accepted (meaning tomorrow is the deadline.)

Is this sentence correct/idiomatic?

It's grammatically correct. Is there a reason you don't just want to tell them "The deadline for submitting your assignments is tomorrow"?

Actually I wanted to know if people talk like that.

Some people do. However, I'd say it's a bit formal for the classroom.

"After" would be more natural.
