We don't really care about the advise of why they did something wrong, it was definitely a mistake and they'll pay a cash fine for their mistake (maybe) and interest on their taxes that are due. However, I don't want the deal to be damaged, and I'm trying to find a work around. I have not found the ability yet online to file an extension after March 15. I'm waiting on a few tax attorneys and accountants to get back to me/them still.
