You close the loopholes where companies have to pay more taxes and it'll be a SIGNIFICANT increase in revenue in this country. Hell, to save small businesses (since that's always the argument about raising business taxes) make it apply to any company that makes more than $500,000 a year or something like that. I would venture to say, you're no longer a "small" business if you are making that much a year from your business.

Also, just the other day, I saw some dude in WV that made $400,000 last year and was actually owed income taxes back! Now, I don't know his actual financial circumstances or anything, but I know damn well that something is fuckin' wrong if he's owed more money after making that much last year.
