I'm just being honest about it, while some seem to want to pretend that they're on some kind of high road.
Your not paying your taxes at all is the same as people not voluntarily paying more than they're required to.
Except for three things:
1) I did pay taxes. I just didn't calculate exactly how much I should have paid and informed the government to adjust for the difference. For all I knew, I could have overpaid on taxes that year and been out a refund.
2) I knew that if I underpaid I would eventually have to pay the difference. All I was doing was delaying the point at which said difference (if any) would have to be paid. At no point did I ever think "I'll never have to deal with this".
3) Addendum to point above: Had it turned out that I had overpaid, the IRS would not have come after me to make sure I got my money back. So to suggest that my action was selfish rather than just foolish is pretty darn ridiculous. I was setting myself up for a situation where I was either screwed because I failed to get a refund I was owed, or I was screwed because I'd eventually have to pay the difference plush penalties and interest.
Oh... And four: This is not, by any definition, tax evasion, fraud, or anything remotely criminal. And I'm still struggling to see how this in any way affects my right to complain about how my government spends my tax dollars. In the grand scheme of taxes I've paid over my lifetime, the amount I'd underpaid that one year is pretty insignificant even if one ignores the fact that ultimately I paid more than that anyway.
And if we really want to get technical, I underpaid during the Bush administration and overpaid during the Obama administration. So um... play politics with that if you want.
