Marginal Combined Federal Taxes on a Family of Four

I am graphing the marginal combined federal taxes on our single earner family of four with three different combinations of tax rates: 

  1. Income only

  2. Income & Payroll (the employee part of social security and medicare)

  3. Income & Payroll (both the employer and employee part of social security and medicare)

The marginal payroll tax rate for this family was 0 until 1979 when the taxable maximum income subject to the payroll tax was greater than this family's median income.

Keep in mind the Tax Policy Center calculate these rates for:

  •  4 person family including a married couple with one earner
  •  Itemized deductions are assumed to equal 23 percent of income through 1986 and 18 percent of income thereafter
