Yes.  I believe the 1040-ES needs to be final but maybe someone who knows for sure can answer. 

No, you can set up direct debit now, you don't need to wait for the paper vouches to be final, you won't be using them.

Maybe.

Well, actually the answer is no, but I don't want to upset our friendly Godfather.  I'm still waiting for my Valentine's chocolates to be delivered and I don't want him to cancel the order.

Cancelled!!!!!!!  Done!  No Chocolate for you!

Fine.  I'll just go back to standing by the door of this place with my sign that says "will work for chocolate".

Raise it high.  

Be careful IRMN that is what Capone told everyone 96 years and 2 days ago.  Give me death or chocolate! Or maybe that was Queen Antonette.

Well, if I am going to have to deal with a guillotine, I would prefer it now instead of having to go through the rest of tax season.
