don't bet on that. They process checks pretty quick...
Yep, the depositing of the checks is independent of doing anything with your return itself.
I'm always impressed how fast the mail goes from my local post office to the IRS service center compared to just about any other mail.
A line on taxes from one of my favorite plays:
GRANDPA: Suppose I pay you this money--mind you, I don't say I'm going to pay it--but just for the sake of argument--what's the government going to do with it.
IRS: Why, the government gives you everything. It protects you.
GRANDPA: What from?
IRS: Well--invasion. If you Foreigners might come over here and take everything you've got.
GRANDPA: Oh, I dont think they're going to do that.
IRS: If you didn't pay an income tax, they would. How do you think the Government keeps up the Army and Navy? All those battleships...
GRANDPA: Last time we used battleships was in the Spanish-American War, and what did we get out of it? Cuba--and we gave that back. I wouldn't mind paying if it were something sensible.
IRS: Sensible? Well, what about Congress, and the Supreme Court, and the President? We've got to pay them, don't we?
GRANDPA: Not with my money--no, sir.
