Cutting Corpoate tax rate to 15% will spur companies to expand, hire more workers who will pay more personal income taxes. The GDP growth under Barry's eight years was 2%, President Trump plans to more than double that.
Also lowering the Corporate Income tax, currently the highest in the World, will bring companies back from overseas.

The ONE TIME 10% tax on repatriated capital held by US Companies overseas if they bring it back and invest in new plants and equipment will generate more revenue when the new income is taxed at higher Corporate rate. The public may be able to buy Infrastructure Bonds as Candidate Trump told Stuart Varney on Fox Business.

The lowering of Personal Income taxes as I heard may include the abolisment of many deductions so some may wind up paying more but tax reporting will be simplified, just like The Late Great Presidents John F. Kennedy and Ronald Reagan.
