I was two weeks later than usual getting my business tax prep completed for the accountant. Why? Because there was one series of thorny transactions that was hard to trace. Finally a prompting by my accountant on a call forced me to do it. They had to file an extension because of this and now personal taxes and college financials are held up, ugh.
As I read this article I have to admit that my claim of being busy was really just ineffectual activity. (Now my wife knows)
