You've answered your own question. If your business spends all its money and reports no profit, then it pays no tax. If you sufficiently co-mingle your personal finances with your business finances (e.g., that vacation to Hawaii was actually a business trip, yeah, that's it), I suspect you can do pretty well with driving down your taxes.

(Note: I don't actually do anything like this, but I can see how you could pull it off.)
