How to Calculate Personal Income Tax
Current Law: Tax Owed = (75,000 – (4,400+4*1144)*Tax Rate – Tax Credits
Tax Owed = (75,000-8,976 = 66,024)*Tax Rate – Tax Credits
Law in 2031: Tax Owed = (75,000 – (24,000+4*1144)*Tax Rate – Tax Credits
Tax Owed = (75,000-28,576 = 46,424) *Tax Rate – Tax Credits
