We owe on federal taxes. That means:

1) I didn’t give the IRS an interest-free loan
[edit]: strictly speaking, I still did, of course – all the withholding is still an interest-free loan, I just managed to keep it below some relatively arbitrary level. In an ideal world, I’d do my own withholding in an account *I* earned the interest on, and just paid my tax bill as a lump sum.
2) I’ll get some cash back since I paid the amount owed on my Discover card

I really don’t get how anyone, outside of those really bad at math, can be happy about getting a refund 🙂

Although, I keep meaning to turn it around – since people *are* happy about getting a refund, I should offer to garnish their wages for a year, earn the interest myself, then pay it back to them as a lump sum (ala the IRS). After all, that makes most people happy and over the course of 3e8 US citizens, the interest would add up a bit.
