Doesn't half the country already pay an effective rate of 0%, with many of them getting credits that actually give them a negative rate? Maybe those credits will go away.
No, it's a little more than 40%. Trump and Bush want to make that number greater than 50%, which is great for pretty much anyone making less than $100,000. It's also great for those making more than $200,000 because the top bracket would get dropped substantially. The people between $100,000-$200,000 would see a cut under Bush, but deductions get capped, so it probably wouldn't be all that substantial. I'm not sure how Trump wants to handle deductions. He probably doesn't know, either.
