The only people who are waiting to file are:
1--people who owe.
2--terminally lazy, particularly if they're getting a refund. Doubly so if they're filing EZ.
C'mon, ****ers. I had my shit done by this time in JANUARY, and all I had to do is tweak it by $40 when I got my W-2. Of course, because of the tax bill that got passed at the last possible second, the IRS wouldn't accept my return for a month afterward, but hey, not like it's MY money or anything, right?
