Earlier quoted context omitted.
Right, you made estimated payments, and it was exactly the right way. You paid based on a reasonable estimation. The point is it's pretty hard to just avoid paying taxes all year (either by plain not paying your self-employment taxes or misrepresenting your situation on a W-4), bank it, and come out clean.
It depends. You argument is very narrow. There are LOTS of ways to avoid paying your fair share of taxes, it depends on the situation and where the cash flows are coming from. As for the Zuckerburg situation, what he did is pretty common. Though I have heard of an alternative to selling those shares, someone in his position could use a portion of his facebook shares as leverage and get a loan to pay the tax man, then…
> get a loan to pay the tax man
Yeah, so he pays the taxes with somebody else's money. Tax man gets paid, right? Tell me the scenario where a guy pays no taxes and isn't in trouble. This is empirically verifiable, but I don't recommend conducting the research.
Sorry for the tangent folks. I'm not commenting on Zuck's situation. The comment about not paying taxes all year is just plain wrong, and I would hate for someone to try it and get dinged. This is especially important for the newer startup people that don't have the usual single W-2 situation. That's all.
