The number one tax break they refer to is stock based comp. If companies paid their execs with cash (i.e. bonuses tied to share price or company performance) instead of shares, they'd have higher cash expense, and therefore wouldn't have those so called profits to tax in the first place. Such an obvious omission in this article indicates this is intentionally misleading.

The next two tax breaks (research and experimentation) and renewable energy seem worthwhile, and I'd guess popular on both sides of the isle.
