IRS. As noted earlier, I got mine done Monday a week ago, and I'm getting refunds from both the Feds and the State.
That's true every year because of how I structure my withholdings. I don't begrudge the government the interest they earn off hanging on to my excess deuctions for a year.
I was pleasantly surprised that the amount of the refunds hadn't changed noticeably this year. We'll see if I can say the same for the 2013 returns.
