   3. Federal income tax liability
      Federal taxable income × Federal income tax rate = Federal income tax liability
   4. Federal payroll tax liability
      Gross income × Federal payroll tax rate = Federal payroll tax liability
2. Calculate your total Colorado state income tax
   1. Colorado state taxable income
      Gross income adjusted − Colorado state standard/itemized deductions = Colorado state taxable income
   2. Colorado state income tax liability
      Colorado state taxable income × Colorado state income tax rate = Colorado state income tax liability
   3. Colorado state payroll tax liability
