Whatever works for you folks, I'm all in. 

I kind of like the deadlines though, because as a deadline draws near, when I ask a client for a document it arrives to me on the same day requested.  Whereas, a month prior, it would take a week, maybe 10 days to get that document. 

So, I propose a super-secret filing deadline, hidden from the public, that only the tax preparers know of.  That way when I make a request I can inform the client that his return is due next week and if I don't get the document today I'll need to file an extension.  Problem solved.  Give me the check mark.
