don't pay Federal Income Tax anyhow, this is actually better than what's going on now. You have to see the whole picture.........
Those making less than $25K (single) and $50K (married) have Fed taxes taken from their paychecks, then get an EIC check when they file.....minus what they have already owed. Trump's plan gives them back ALL of what they paid PLUS the EIC putting more into their actual pockets with THEM having all the power to decide where to spend it instead of the Feds keeping what they paid and spending it FOR them. That money goes back into the REAL economy.....mostly LOCAL spending in their communities.....and still pays the taxes on those purchases with the money going to the city/county/State more than the Feds (some would be spent on the Fed taxes on utility bills and gasoline).
Using that logic, one step further to take control away from the Feds is to stop the practice of the State collecting those funds, sending it all to the Feds, and have the Feds decide how much to send back to the State later on. The way it's done now is with the Feds in control, for example, the State of Virginia could be sending $30B to the Feds, the Feds then pick and choose, based on what other States have put the most pressure on the Feds with various bills passed in Congress, which States will get the largest and smallest portions doled out. (Spread the wealth again) If Maine got more bills passed than Virginia, a good portion of VA's funds would be sent to Maine instead of returned to Virginia.
As for the revenue your guy is talking about......if more people got to keep more of their own money, they would have a larger incentive to work (especially with Welfare Reform again coming into play like Clinton/Gingrich did), thus more people working means more revenue in all tax brackets. He also will be using a lower tax penalty bracket for corporations to bring back their money from overseas, giving THEM the incentive to invest here again, creating even more jobs for the middle class again, thus more revenue again.
As he said in his announcement of his tax policy....this area is HIS wheelhouse and he's looking at an entire package, which is what he is really good at.
