LAB ASSIGNMENT A8.2 page 17 of 17

IRS

Background:

Federal income tax rates can be calculated using tax rate schedules. The following are tax rates for two out of the four categories used by the IRS in 2001:

Schedule X - Single

If your taxable income is:

over -
but not over -
your tax is
of the amount over -
$ 0
$ 27,050
15 %
$ 0
27,050
65,550
$ 4,057.50 + 27.5 %
27,050
65,550
136,750
$ 14,645.00 + 30.5 %
65,550
136,750
297,350
$ 36,361.00 + 35.5 %
136,750
297,350
---------
$ 93,374.00 + 39.1 %
297,350

Schedule Y-1 - Married filing jointly

If your taxable income is:

over -
but not over -
your tax is
of the amount over -
$ 0
$ 45,200
15 %
$ 0
45,200
109,250
$ 6,780.00 + 27.5 %
45,200
109,250
166,500
$ 24,393.75 + 30.5 %
109,250
166,500
297,350
$ 41,855.00 + 35.5 %
166,500
297,350
---------
$ 88,306.00 + 39.1 %
297,350

To test your understanding, follow this example of a single person with taxable income of $68,000:
Tax is $14,645.00 + 0.305*(68000-65550) = $14,645.00 + $747.25 = $15,392.25

Assignment:

  1. One of the biggest mistakes that beginning programmers tend to make is to attempt solving the problem within their code before they really understand how to work the problem. Use the following values and solve each of them before you begin to write your program out.

    a. $50,000 Married __________
    b. $25,000 Single __________
    c. $300,000 Married __________
    d. $170,000 Single __________
    e. $30,000 Married __________
    f. $500,000 Single __________
    g. $170,000 Married __________
    h. $45,000 Single __________
    i. $130,000 Married __________
    j. $120,000 Single __________

     

  2. Write a class that:

    1. Prompts the user for the following information:

      Filing status: Single or Married (entered as 1 for Single and 2 for Married)
      Taxable income

    2. Calculates and prints:

      Filing status
      Taxable income
      Federal tax

  3. Example run:

Enter marital status (1=single, 2=married): 1
Enter taxable income: $ 35125
Your Federal tax = $ 6,278.13

  1. Use these values for your run output:

    Single, $15,500

    Single, $100,000

    Single, $ 480,000

    Married, $50,000

    Married, $125,000

    Married, $ 400,000
