SECTION I: HISTORY OF TAXATION, HIERARCHY OF LAWS & EQUITY
CRITERIA
Question 1: In what year did the U.S. Supreme Court rule the individual income tax
unconstitutional, leading to a temporary halt in its implementation?
A. 1861
B. 1894
C. 1895
D. 1913
ANSWER : C. 1895
Explanation: In 1895, the U.S. Supreme Court ruled the individual income tax unconstitutional in the Pollock v.
Farmers' Loan & Trust Co. decision [1]. An income tax was previously reinstated in 1894 but was struck down the
following year [18]. The first federal income tax was enacted in 1861 to finance the Civil War [18], and the
constitutional path for income tax was permanently established in 1913 with the ratification of the 16th
Amendment [18].
Question 2: Which of the following constitutional amendments, ratified in 1913, officially granted
the U.S. Congress the power to lay and collect taxes on incomes without apportionment among
the several states?
A. 14th Amendment
B. 16th Amendment
C. 18th Amendment
D. 21st Amendment
ANSWER : B. 16th Amendment
Explanation: The ratification of the 16th Amendment in 1913 provided the permanent constitutional foundation
for the federal individual income tax [18]. This amendment overcame the 1895 Supreme Court ruling by explicitly
permitting Congress to levy taxes on income from whatever source derived, without apportionment [18].

Question 3: During which historical period did the U.S. income tax transition from a 'class tax'
affecting only wealthy individuals into a 'mass tax' that applied to the majority of citizens?
A. Civil War (1861)
B. World War I (1917)
C. World War II (1940)
D. The Tax Reform Act of 1986
ANSWER : C. World War II (1940)
Explanation: During World War II (specifically beginning in 1940), the federal income tax became a 'mass tax'
[18]. The government dramatically lowered exemptions and increased rates to raise massive revenues to finance
the war, bringing millions of middle- and low-income citizens into the tax net for the first time.
Question 4: What year was the 'pay-as-you-go' tax withholding system established in the United
States, requiring employers to deduct income taxes directly from employee paychecks?
A. 1913
B. 1939
C. 1943
D. 1986
ANSWER : C. 1943
Explanation: The 'pay-as-you-go' withholding system was introduced in 1943 [18]. This critical administrative
mechanism was designed to assist the government in collecting the massive revenues required during World War
II by ensuring taxes were withheld dynamically from wage payments rather than collected in a single lump sum
the following year.
Question 5: Which of the following represents the absolute highest statutory authority within the
Legislative branch's tax law hierarchy?
A. Treasury Regulations
B. Congressional Committee Reports
C. Internal Revenue Code
D. Revenue Rulings
ANSWER : C. Internal Revenue Code
Explanation: The Internal Revenue Code (currently the IRC of 1986, as amended) stands at the absolute top of
the legislative hierarchy of tax law authority [1, 18]. Congressional Committee Reports are also legislative sources
but are used primarily to interpret legislative intent [1]. Treasury Regulations and Revenue Rulings are
administrative (Executive) sources [18, 19].

from the Legislative branch of government?
A. Revenue Procedures
B. Congressional Committee Reports
C. Income Tax Regulations
D. Letter Rulings
ANSWER : B. Congressional Committee Reports
Explanation: Within the Legislative branch, Congressional Committee Reports (from the House Ways and
Means, Senate Finance, and Joint Conference Committees) serve as crucial primary sources of tax law, detailing
the intent of the lawmakers who drafted the statutory language [1]. Revenue Procedures, Income Tax
Regulations, and Letter Rulings are administrative sources issued by the Executive branch (IRS/Treasury) [18,
19].
Question 7: Under the criteria for an equitable tax structure, a tax that minimizes the compliance
burdens and costs for the taxpayer, while minimizing administrative costs for the government, is
said to meet the standard of:
A. Simplicity
B. Convenience
C. Certainty
D. Economy
ANSWER : D. Economy
Explanation: The criterion of 'Economy' dictates that a tax structure should involve minimal compliance costs for
taxpayers and minimal administrative costs for the government [1]. 'Simplicity' refers to the understandability of
the tax code [1], 'Convenience' refers to the lack of heavy recordkeeping/compliance burdens [1], and 'Certainty'
represents the stability and predictability of tax liabilities [2].
Question 8: If a tax structure is designed so that taxpayers can easily comprehend the rules and
calculate their tax liabilities without professional assistance, which criterion of equity does it
satisfy?
A. Equity
B. Simplicity
C. Convenience
D. Certainty
ANSWER : B. Simplicity
Explanation: The 'Simplicity' criterion is defined as the understandability of the tax structure [1]. A simple tax
structure allows ordinary taxpayers to comprehend how their taxes are computed without facing excessive
complexity.
