My guess, and it’s just that at this time is that his ‘business’ tax replaces current corporate and current chapter S taxes and let’s you count all expenses now! That would be a significant improvement. I’d prefer taxing the broadest possible income base all at the same low rate and all just once. But that may be a bridge too far at this time.
The problem with his flat "business tax" is it's A NEW TAX with new rules.
Fine, you have a business, you pay 16% "business tax" on the business earnings...Where and how does the business owner's earnings get taxed?
Obviously his tax plan is already causing confusion. Before it's finished it will have more pages than Obamacare.
