@Jim-from-Ohio they don't know about it Jim and many of them have taken a few days off after the October 16th deadline. If I did not receive that NSTP email yesterday then I wouldn't have known about it either. When they come back from their vacation and go to EFTPS then they will be in for a surprise. Oh by the way, that is why I try to belong to as many organizations as possible and try to buy as much tax reference material as possible, because there's always something like this when it's well worth the fees.
