This assignment will give you more experience on the use of:
1. integers (int)
2. floats (float)
3. conditionals(if statements)
4. iteration(loops)
Functions, lists, dictionary, classes CANNOT BE USED!!!
The goal of this project is to make a fictitious comparison of the federal income. You will ask the user to input their taxable income. Use the income brackets given below to calculate the new and old income tax. For the sake of simplicity of the project we will only consider individuals and not married users. We will also ignore any tax deductions while calculating income tax—they can significantly alter the tax, but add too much complexity for our programming project.
New income tax brackets (2018 and newer)
10% Up to $9,525
12% $9,526 to $38,700
22% $38,701 to $82,500
24% $82,501 to $157,500
32% $157,501 to $200,000
35% $200,001 to $500,000
37% over $500,000
Old income tax brackets (2017 and older)
10% Up to $9,325
15% $9,326 to $37,950
25% $37,951 to $91,900
28% $91,901 to $191,650
33% $191,651 to $416,700
35% $416,701 to $418,400
39.6% over $418,400
Assignment Background
Being in the 25% tax bracket doesn’t mean you pay 25% on everything you make. The progressive taxsystem means that people with higher taxable incomes are subject to higher tax rates, and people withlower taxable incomes are subject to lower tax rates.
For example, let’s say you’re a filer with $32,000 in taxable income. That puts you in the 15% taxbracket in 2017. But do you pay 15% on all $32,000? No. Actually, you pay only 10% on the first$9,325; you pay 15% on the rest. (Look at the tax brackets above to see the breakout.)
If you had $50,000 of taxable income, you’d pay 10% on that first $9,325 and 15% on the chunk ofincome between $9,326 and $37,950. And then you’d pay 25% on the rest, because some of your$50,000 of taxable income falls into the 25% tax bracket. The total bill would be $8,238.75 — about16% of your taxable income, even though you’re in the 25% bracket.
Project Description
Your program must meet the following specifications:
1. At program start, prompt the user for their income
2. Repeatedly prompt the user for new income until a negative income is entered.
3. Calculate the income tax using the 2017 and 2018 tax bracket tables above.
4. For each income entered:
a. Calculate the 2017 income tax and store it in a variable.
b. Next calculate the 2018 income tax and store it in a variable
c. Print
i. The income
ii. The 2017 taxi
iii. The 2018 tax
iv. The difference between the 2018 and 2017 tax rounded to cents
v. The difference between the 2018 and 2017 tax as a percentage of the 2017 taxrounded to cents
Assignment Notes
1. To clarify the project specifications, sample output is appended to the end of this document.
2. Use a while loop with a Boolean that keeps looping as long as the income is greater than or equal to zero.
3. Prompt for income before the loop and remember to convert the input string to an int (so you are comparing an int in your Boolean expression). Remember to prompt again at the end (aka “bottom”) of the loop.
4. There will be no error checking in this assignment. If a float or a string is entered at the prompt, the program will crash.
