Information Packet on Taxation Systems
Collecting taxes is the way governments make money to provide services for the
common good and to assist special needs. There are various systems for collecting taxes. We
will investigate three of those systems.
Section I: Types of Tax Systems
A) Progressive
Proportional
Regressive
Progressive Income Tax: Our present federal and state taxes are based upon a system where a
higher percent of tax is imposed on higher levels of income. Following is an example:
2007 Federal Tax Rate Schedules
Note: These tax rate schedules are provided so that you can compute your federal estimated income tax for 2007.
To compute your actual income tax, please see the instructions for 2007 Form 1040, 1040A, or 1040EZ as
appropriate when they are available.
Schedule X — Single
If taxable income is over--
But not over--
The tax is:
\$0
\$7,825
10% of the amount over \$0
\$7,825
\$31,850
\$782.50 plus 15% of the amount over 7,825
\$31,850
\$77,100
\$4,386.25 plus 25% of the amount over 31,850
\$77,100
\$160,850
\$15,698.75 plus 28% of the amount over 77,100
\$160,850
\$349,700
\$39,148.75 plus 33% of the amount over 160,850
\$349,700
no limit
\$101,469.25 plus 35% of the amount over 349,700
Proportional Tax: A tax where higher levels of income or property are taxed at the same rate
as lower levels of income. An example would be local property tax. If the property tax rate is
5%, then the following would apply.

Regressive Tax: A tax where higher levels of income are taxed at lower tax rates. Example:
Local and State sales taxes. Assume 5% tax rate.
Income
Amount Spent
Taxes
Effective Tax Rate
\$25,000
\$25,000
\$25,000 x .05 = \$1,250
\$1,250/\$25,000 = 5%
\$60,000
\$53,000
\$53,000 x .05= \$2,650
\$2,650/\$60,000 = 4.4%
Section 2: Recently, some groups have suggested changes in the Federal Income Tax System.
Some of the proposed change include the following plans.
National Sales Tax: Replace the entire income tax system with a national sales tax. You would pay
your federal taxes whenever you purchased a product or service. This means that the federal
government would no longer withhold federal taxes from your paycheck - you get to keep more of what
you make. You would no longer need to file federal income tax forms - the federal income tax system
would be abolished. All families will receive a monthly tax rebate check if they overpay. This would be
considered a regressive tax. For our purposes we will choose 20% as the National Sales Tax Rate.
Flat Tax: A true flat tax would provide a greater degree of equity if all income regardless of source
would be taxed equally. It would only provide that equity if income from labor, dividends, capital gains, or
from any source would be considered taxable income. In additions, it would be necessary to eliminate all
deductions or adjustments, credits, etc. without exceptions. A true flat tax is proportional. For our
purposes we will choose 20% as the Flat Tax Rate.
Progressive Tax: In this situation the tax rate increases as the amount to which the rate is applied
increases. The term "progressive tax" describes a distribution effect, which can be applied to any type of
tax system (income or consumption) that meets the definition. It is frequently applied in reference to
income taxes, where people with more income pay a higher percentage of that income in tax than do
those with less income. Our federal and state income tax codes were created in 1916 with a progressive
tax structure.
Section 3: How do these tax plans compare? Here is an example.
John Doe is salaried and makes \$60,000 annually. He earned \$500 in interest from a
savings account at HSBC during 2007. He did not serve in Afghanistan or Iraq and,
therefore, received no combat pay. Nor is he eligible for the Earned Income Credit because
his earned income is too high. His filing status is single and his tax liability is \$8,371. He
has already had \$4,000 in withholding tax deducted from his pay during the year according
to his W-2 form. Therefore, he owes the difference.
In addition, of the \$60,000 he earned, he calculated that he spent \$53,000. The local and
state sales tax rate combines to 6.75%.
The market value of his home is \$300,000 is assessed at 60% of its value at the tax rate of
12%.
Under the current Progressive Tax (Federal) Plan: John’s sales tax rate is regressive
and his property tax rate is proportional. What is his total tax liability for the year?

A. Income tax liability = \$8,371 (Form 1040EZ)
B. Sales Tax Liability (local and state) = \$53,000 x .0675 = \$3,578 (rounded)
C. Property Tax = \$300,000 x .60 = \$180,000 x .05 = \$9,000
D.Total Tax Liability = \$20,949 (\$8,371+\$3,578+\$9,000)
Problem 2: What would be his tax liability if congress switched from the progressive
tax system to A) Flat Tax or B) National Sales Tax?
A) Flat Tax:
Income Tax - \$60,500 x .20 - \$13,000
Property Tax - \$9,000 (remains at 5% for local tax)
Sales Tax (local and state) - \$3,578 (remains at 6.75% for local tax)
Total Tax = \$24,578
B) National Sales Tax:
Income Tax - \$53,000 x .20 = \$10,600
Property Tax - \$9,000 (remains at 5% for local tax)
Sales Tax – (local and state) - \$3,578 (remains at 6.75 for local tax)
Total Tax = \$23,178

Section 4: Changing the tax system is serious business, if such a decision were made some
serious questions need to be addressed. Some considerations are:
A.
B.
C.
D.
E.
F.
G.
H.
Is it important to spread tax responsibility equitably?
Should everyone pay the same tax rate or should some pay less, some more?
Should taxes be more the responsibility of the rich than the poor?
Should businesses be taxed more or less than the individual?
Are taxes too high?
If taxes are lowered, is the amount of money taken in by government changed?
If it is changed, how does the government deal with the shortfall?
If taxes are too high, does it contribute to government waste?

Student Taxation Project Packet
Name: __________________________________
Select a profession or career that you would like to pursue. Investigate the
average salary for someone in this career. Use this salary to compute your tax
liability under each of the three tax plans that were presented. Assume you have
savings that earn \$350 interest for the year. You have no other income and are
not eligible for any earned income credits. You file your Federal Income Tax with
single status, but have not had any withheld at work. The amount of income you
spent on items that require sales tax is dependent on your income.
If you earn between \$1 and \$20,000 you will spend 99% of your income.
If you earn between \$20,001 and \$50,000 you will spend 92% of your income.
If you earn between \$50,001 and \$100,000 you will spend 88% of your income.
If you earn over \$100,000 you will spend 85% of your income.
The local and state combined sales tax rate is 8.75%. You own a home with a
market value of \$150000, which is assessed at 65% of its value with a tax rate of
13%.
