Learning Objectives Key Points
LO 1.1:
Understand the history and
objectives of U.S. tax law.
The income tax was authorized by the Sixteenth Amendment to the Constitution on
March 1, 1913.
In addition to raising money to run the government’s programs, the income tax is used as
a tool of economic and social policies.
Examples of economic tax provisions are the limited allowance for expensing capital expen-
ditures and the accelerated cost recovery system (ACRS or MACRS) of depreciation. The
charitable contribution deduction is an example of a social tax provision.
LO 1.2:
Describe the different entities
subject to tax and reporting
requirements.
Individual taxpayers file Form 1040EZ, Form 1040A, or Form 1040.
Corporations must report income annually on Form 1120 and pay taxes.
An S corporation generally does not pay regular corporate income taxes; instead, the
corporation’s income passes through to its shareholders and is included on their individ-
ual tax returns.
A partnership files Form 1065 to report the amount of income or loss and show the
allocation of the income or loss to the partners.
Generally, all income or loss of a partnership is included on the tax returns of the partners.
LO 1.3:
Understand and apply the tax
formula for individuals.
AGI (adjusted gross income) is gross income less deductions for adjusted gross income.
AGI less the larger of itemized deductions or the standard deduction and less exemption
amounts equals taxable income.
Appropriate tax tables or rate schedules are applied to taxable income to calculate the
gross tax liability.
The gross tax liability less credits and prepayments equals the tax due or refund due.
LO 1.4:
Identify individuals who must file
tax returns and select their correct
filing status.
Conditions relating to the amount of the taxpayer’s income and filing status must exist
before a taxpayer is required to file a U.S. income tax return.
Taxpayers are also required to file a return if they have net earnings from self-employment
of $400 or more, receive advanced earned income credit payments (AEIC), or owe taxes
such as Social Security taxes on unreported tips.
There are five filing statuses: single; married, filing jointly; married, filing separately; head
of household; and qualifying widow(er).
LO 1.5:
Calculate the number of exemp-
tions and the exemption amounts
for taxpayers.
Taxpayers are allowed two types of exemptions: personal and dependency.
For 2010, each exemption reduces adjusted gross income by $3,650. Prior to 2010, high-
income taxpayers were subject to phase-outs of both exemptions and itemized deductions.
The phase-outs may be reinstated in 2011.
Personal exemptions are granted to taxpayers for themselves and their spouse.
Extra exemptions may be claimed for each person other than the taxpayer or spouse who
qualifies as a dependent. A dependent is an individual who is either a qualifying child or a
qualifying relative.
LO 1.6:
Calculate the correct standard or
itemized deduction amounts for
taxpayers.
The standard deduction was placed in the tax law to provide relief for taxpayers with few
itemized deductions.
For 2010, the standard deduction amounts are: Single $5,700; Married, filing jointly
$11,400; Married, filing separately $5,700; Head of household $8,400; Qualifying
widow(er) $11,400.
Taxpayers who are 65 years of age or older or blind are entitled to additional standard
deduction amounts of $1,400 for unmarried taxpayers and $1,100 for married taxpayers
and surviving spouses in 2010.
