Tax Deductions for Individuals: A Summary
Summary
Every tax filer has the option to claim deductions when filing their income tax return. Deductions
serve four main purposes in the tax code: (1) to account for large, unusual, and necessary personal
expenditures, such as extraordinary medical expenses; (2) to encourage certain types of activities,
such as homeownership and charitable contributions; (3) to ease the burden of taxes paid to state
and local governments; and (4) to adjust for the expenses of earning income, such as
unreimbursed employee expenses.
Some tax deductions can be taken by individuals even if they do not itemize. These deductions
are commonly referred to as above-the-line deductions, because they reduce a tax filer’s adjusted
gross income (AGI, or the line). In contrast, itemized and standard deductions are referred to as
below-the-line deductions, because they are applied after AGI is calculated to arrive at taxable
income.
Tax filers have the option to claim either a standard deduction or to itemize certain deductions.
The standard deduction, which is based on filing status, is, among other things, intended to reduce
the complexity of paying taxes, as it requires no additional documentation. Alternatively, tax
filers claiming itemized deductions must list each item separately on their tax return and be able
to provide documentation that the expenditures being deducted have been made. Only tax filers
with deductions that can be itemized in excess of the standard deduction find it worthwhile to
itemize. Whichever deduction the tax filer claims—standard or itemized—the amount is
subtracted from AGI.
Deductions differ from other tax provisions that can reduce a tax filer’s final tax liability.
Deductions reduce final tax liability by a percentage of the amount deducted, because deductions
are calculated before applicable marginal income tax rates. In contrast, tax credits generally
reduce an individual’s tax liability directly, on a dollar-for-dollar basis, because they are
incorporated into tax calculations after marginal tax rates are applied.
Some deductions can only be claimed if they meet or exceed minimum threshold amounts
(usually a certain percentage of AGI), in order to simplify tax administration and compliance. In
addition, some deductions are subject to a cap (also known as a ceiling) in benefits or eligibility.
Caps are meant to reduce the extent that tax provisions can distort economic behavior, limit
revenue losses, or reduce the availability of the deduction to higher-income tax filers.
Because some tax filers and policymakers may not have detailed knowledge of tax deductions,
this report first describes what they are, how they vary in their effects on reducing taxable
income, and how they differ from other provisions (e.g., exclusions or credits). Next, a discussion
concerning the rationale for deductions as part of the tax code is provided. Because some
deductions are classified as tax expenditures, or losses in federal revenue, they might be of
interest to Congress from a budgetary perspective. The final section of this report includes tables
that summarize each individual tax deduction, under current law. Many of these deductions are
part of the permanent income tax code. The American Taxpayer and Relief Act of 2012 (H.R. 8,
as enactedP.L. 112240) extended several temporary provisions through 2012 and 20132013. The Tax Extender Act of 2013 (S.
1859) would provide a one-year extension for nearly all of the provisions scheduled to expire at
the end of 2013.
This report will be updated, as necessary, to reflect changes in current law.

Tax Deductions for Individuals: A Summary
T
his report provides an overview of income tax deductions for individuals. A tax deduction
reduces the amount of a tax filer’s income that is subject to taxation, ultimately reducing
the tax filer’s tax liability. Every tax filer has the option to claim deductions when filing
their income tax return. However, some tax filers and policymakers may not have detailed
knowledge of tax deductions, including future changes in the requirements to claim certain
deductions. In addition, tax deductions may be of interest to Congress from a budgetary
perspective, as some deductions are classified as tax expenditures, and result in losses in federal
revenue.
This report first describes what tax deductions are, how they vary in their effects on reducing
taxable income, and how they differ from other provisions (e.g., exclusions or credits). Next, it
discusses the rationale for deductions as part of the tax code. The final section includes tables that
summarize each individual tax deduction, under current law.
This report focuses on the standard treatment of tax deductions for individuals under the
individual income tax code. As such, the following are beyond the scope of this report:
•
the different treatment of deductions under the alternative minimum tax for
individuals,1
•
tax deductions for businesses under the individual income tax code,2 and
•
options for reforming itemized deductions.3
This report will be updated, as necessary, to reflect changes in current law.
Calculating the Individual Income Tax
To understand what tax deductions are, it is helpful to first understand how a tax filer calculates
individual income tax liability. Figure 1 provides an overview of how a tax filer calculates his or
her federal tax liability.4 To calculate taxes owed (tax liability), tax filers first add up all of their
forms of income (see step 1 in Figure 1) to calculate their gross income. Next, the tax filer
subtracts any above-the-line deductions to calculate their adjusted gross income, or AGI (step 2).
AGI is often referred to as “the line.” Then, the tax filer subtracts personal exemptions, or fixed
dollar amounts per spouse and dependent child (step 3). The tax filer then subtracts the greater of
either the sum of all of their below-the-line, or itemized deductions, or the standard deduction,
which is a fixed amount based on filing status, in order to arrive at taxable income (step 4). The
marginal tax rates are applied to taxable income (step 5) to arrive at a preliminary tax liability.

See CRS Report RL30149, The Alternative Minimum Tax for Individuals, by Steven Maguire.
Some of the deductions reported on the Internal Revenue Service Form 1040 relate to business expenses, as some
business are organized as pass-through entities. Pass-through entities get their name from the fact that the business’s
income passes-through to the owner, as opposed to being claimed separately by the business. However, the tax
treatment of business income through the individual tax code is beyond the scope of this report. For more information
on pass-through entities, see CRS Report R40748, Business Organizational Choices: Taxation and Responses to
Legislative Changes, by Mark P. Keightley.

What Are Tax Deductions?
Simply stated, deductions reduce taxable income. Each deduction reduces tax liability by the
amount of deduction times the tax filer’s marginal tax rate. In contrast, a tax credit reduces tax
liability on a dollar-for-dollar basis because it would be applied after the marginal tax rate
schedule. An individual in a 35% tax bracket would receive a reduction in taxes of $35 for each
$100 deduction while an individual in a 25% tax bracket would receive a reduction in taxes of
$25 for each $100 deduction. Hence, the same deduction can be worth different amounts to
different tax filers depending on their marginal tax bracket. More simply stated, theThe tax savings
from deductions are
generally equal to the tax filer’s marginal tax rate times the amount of the
deduction. So higher-incomehigherincome tax filers typically benefit more than lower-income tax filers from
deductions.

Tax Deductions for Individuals: A Summary
Deductions serve four main purposes in the tax code.5 First, they can account for large, unusual,
and necessary personal expenditures, such as the deduction for extraordinary medical expenses.
Second, they are used to encourage certain types of activities, such as homeownership and
charitable contributions. Third, they account for and ease the burden the burden of paying for
non-federal forms of taxes, such as state and local taxes. Fourth, deductions adjust for the
expenses of earning income, such as deductions for work-related employee expenses.
The following sections define each form of deduction and explain in greater detail how
deductions are used in the calculation of an individual’s tax liability.
Above-vs.-Below-the-Line Deductions
To arrive at final tax liability, all taxpayers may be able to claim above-the-line deductiondeductions
whether they claim itemized deductions or the standard deduction. Each of these deductions has a
specific line on the Form 1040 (e.g., line 34 for the deduction of student loan interest). Figure 2
shows how tax deductions appear on the 2011 IRS Form 1040.

Tax Deductions for Individuals: A Summary
These deductions are commonly referred to as above-the-line deductions, because they reduce a
tax filer’s AGI (the line). Above-the-line deductions are sometimes also called adjustments to
income, because they generally represent costs incurred to earn income. In contrast, itemized and
standard deductions are sometimes referred to below-the-line deductions, because they are
applied after AGI is calculated to arrive at taxable income.
Above-the-line deductions may provide additional benefits to some tax filers seeking to claim
certain tax preferences. A number of tax provisions have a phaseout of benefits as income
increases. The higher the AGI, the less likely the tax filer will be able to claim a larger value of
the tax preference. Tax deductions that lower AGI increase the likelihood that the tax filer will be
able to claim a larger value of the tax preference.
Itemized Versus Standard Deductions
As previously discussed, tax filers have the option to claim either a standard deduction or the sum
of their itemized deductions. Whichever deduction the tax filer claims—standard or itemized—
the deduction amount is subtracted from AGI to arrive at final tax liability.
Standard Deduction
The standard deduction is a fixed amount, based on filing status, available to all taxpayers. In
contrast to those itemizing their deductions, tax filers do not have to provide additional
documentation in order to claim the standard deduction.
The standard deduction was introduced into the federal tax code with the passage of the
Individual Income Tax Act of 1944 (P.L. 78-315) primarily to simplify tax administration and
compliance. At the time of passage, it was noted that taxpayers generally had little idea about
what deductions were allowable and few taxpayers kept accurate records. Thus, the enactment of
the standard deduction reduced excessive unsupportable claims of deductions, although at the
same time it permitted many taxpayers to take a deduction in excess of what they would have
been allowed if they had been required to itemized their deductions.
Today it is also viewed as performing a social welfare purpose. The social welfare purpose of the
standard deduction was introduced with the minimum standard deduction in the Revenue Act of
1964 (P.L. 88-272). Under this minimum standard deduction provision, a taxpayer was assured a
minimum amount of deductions from his or her income. The personal exemptions combined with
the standard deduction amount are designed to remove low-income households from the tax rolls,
and exempt a minimum level of income from taxation for other mode.
The calculation of the standard deduction has changed over time. In 1944, it was equal to 10% of
AGI, up to a maximum of $1,000. In 1964, a minimum standard deduction was introduced as a
fixed value of $200 plus $100 for each exemption with a ceiling of $1,000 if married filing
jointly.6 The value of the standard deduction, including both the percent of AGI and the maximum
value, was increased multiple times from 1969 to 1975. The minimum standard deduction and the
deduction were merged in 1977 into a flat standard deduction of $2,200 (single) and $3,200

deduction were merged in 1977 into a flat standard deduction of $2,200 (single) and $3,200
(married filing jointly).7 The Economic Recovery Tax Act of 1981 (P.L. 97-34) indexed standard
deduction amounts for inflation, beginning in 1985.8 The standard deduction has been increased
over time, such as with the Tax Reform Act of 1986 (TRA86; P.L. 99-514).
The Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16)
phased out part of the so-called marriage penalty associated with the federal tax code, where the
standard deduction for joint filers was less than twice the single filer amount. EGTRRA increased
the deduction for joint filers to 200% of singles. This provision, most recently extended by Tax
Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 (P.L. 111-312),
will expireexpired in 2012. Under current law, the standard deduction for married couples filing jointly
will will
be equal to 167% of upper limit for singles for the 2013 tax year and beyond.9
The standard deduction amount varies depending on the filing status of the tax unit (i.e., single,
married filing jointly, married filing separately, or head of household), whether the tax filer is
over the age of 65, and whether the tax filer is blind.
For the 20122013 tax year (2014 filing season), the inflation-adjusted
standard deductions are as
follows:
•
$11,90012,200 for married filing jointly or qualified widow(er)s;
•
$5,950surviving spouses,
•
$6,100 for single tax filers and married filing separately, and
•
$8,950 for tax filers who qualify as the head of a household.10
For the 2014 tax year (2015 filing season), the inflation-adjusted standard deductions are
as follows:
•
$12,400 married filing jointly or surviving spouses,
•
$6,200 for single tax filers and married filing separately;, and
•
$8,7009,100 for tax filers who qualify as the head of a household.1011
In addition, there is a standard deduction available for an individual who can be claimed as a
dependent on another person’s tax return. The standard For tax year 2013 (2014 filing season), the standard
deduction for a dependent is generally
limited to the greater of $950 (in 2012) or the : (a) $1,000 or (b) the sum of the
individual’s earned income for the year, plus $300
(but not more than the regular standard
deduction amount of $5,9506,100 for single tax filers).12
The additional standard deductions for those aged 65 or older and those who are legally blind are
increased by $1,450500 if single or head of household and $1,150 if married filing jointly. These
increases apply per classification and are added above the base standard deduction amounts listed
above. Thus, a 70-year-old blind and single tax filer would be eligible for a $2,900 increase
($1,450 for being 65 or older, and $1,450 for being blind) in his or her standard deduction. These
amounts are adjusted annually for inflation.11

2013 (2014 filing season).13 These increases apply per classification and are added above the base
standard deduction amounts listed above. Thus, a 70-year-old blind and single tax filer would be
eligible for a $3,000 increase ($1,500 for being 65 or older, and $1,500 for being blind) in his or
her standard deduction for tax year 2013. These amounts are adjusted annually for inflation.
Itemized Deductions
Alternatively, tax filers claiming itemized deductions must list each item separately on their tax
return and be able to provide documentation (i.e., in the event of an IRS audit) that the
expenditures have been made.
Tax filers have been able to itemize their deductions since the Revenue Act of 1913 (P.L. 63-16),
which created the first permanent federal income tax. Deductions for interest paid or unexpected
casualty losses were early provisions in the federal income tax code because many businesses
were sole proprietorships (i.e., pass-through entities) where the owner was personally liable for
the costs of doing business. Itemized deductions have been reduced or limited in eligibility, most
notably with TRA86. For example, TRA86 eliminated deductions for consumer interest and
enacted more complex rules for deducting investment interest.1214
Only individuals with aggregate itemized deductions greater than the standard deduction find it
worthwhile to itemize. Itemized deductions are claimed on the IRS Schedule A form.1315 Itemized
deductions are allowed for a variety of purposes. A detailed summary of the requirements and
limits for each of these provisions, and other itemized deductions, is included in Table 2, at the
end of this report.
Some itemized deductions can only be claimed if they meet or exceed minimum threshold
amounts (usually a certain percentage of AGI) in order to simplify tax administration and
compliance. For example, a tax filer must meet a certain threshold (or a floor) to deduct a
casualty, disaster, or theft loss.
Certain itemized deductions are treated as miscellaneous itemized deductions, which are allowed
only to the extent that their total exceeds 2% of the individual tax filer’s AGI. This floor makes it
simpler for a tax filer to choose whether he or she would be better off itemizing the deductions or
choosing to claim the standard deduction, and it helps to ensure that the IRS is only reviewing
documentation of fewer, larger events rather than many, smaller events. Any restriction placed
upon an itemized deduction generally applies prior to the 2% AGI floor.1416 An example of an
expense subject to the combined 2% of AGI floor for miscellaneous deductions is the 50%
reduction for unreimbursed meals while traveling away from home on business.
In addition, some deductions are subject to a cap (also known as a ceiling) in benefits or
eligibility. Caps are meant to reduce the extent that tax provisions can distort economic behavior,
limit revenue losses, or reduce the availability of the deduction to higher-income tax filers. For
example, the home mortgage interest itemized deduction is limited to mortgage debt in the
amount of up to $1 million for married couples filing jointly ($500,000 for individuals or married
1213
For the 2014 tax year (2015 filing season), the additional standard deduction for the aged or the blind is 1,200. The
additional standard deduction amount is increased to $1,550 if the individual is also unmarried and not surviving a
spouse. See ibid.

Tax Deductions for Individuals: A Summary
In addition, some deductions are subject to a cap (also known as a ceiling) in benefits or
eligibility. Caps are meant to reduce the extent that tax provisions can distort economic behavior,
limit revenue losses, or reduce the availability of the deduction to higher-income tax filers. For
example, the home mortgage interest itemized deduction is limited to mortgage debt in the
amount of up to $1 million for married couples filing jointly ($500,000 for individuals or married
filing separate).17filing separate).15 This ceiling is intended to limit incentives for higher-income tax filers to
finance their home purchases with deductible interest.
Pease Limit on Itemized Deductions for Higher-Income Tax Filers
There is a limitation on the value of itemized deductions that certain, higher-income tax filers can
claim. The limitation on itemized deductions was initially included in the Omnibus Budget
Reconciliation Act of 1990 (P.L. 101-508), drafted by Representative Donald Pease of Ohio.
Commonly referred to as “Pease” by tax analysts, it effectively increases taxes on high-income
tax filers without explicitly increasing tax rates.
Pease’s limitations are triggered by an AGI threshold.1618 The number or total amount of itemized
deductions claimed by a tax filer does not determine whether he or she is subject to Pease. Pease
affects tax filers above the inflation-adjusted AGI thresholds who itemize deductions. For these
tax filers, the total of certain itemized deductions is reduced by 3% of the amount of AGI
exceeding the threshold.1719 The total reduction, however, cannot be greater than 80% of the
deductions (and the tax filer always has the option of taking the standard deduction).
Consequently, the effective marginal tax rate for these tax filers will be 3% higher than their
statutory marginal tax rate.1820
Pease was in effect from 1991 to 2009, and was fully repealed from 2010 to 2012.1921 The
Economic Growth and Tax Relief Reconciliation Act of 2001 (P.L. 107-16) included the phasedin repeal of Pease between 2006 and 2009. Pease was scheduled to be reinstituted beginning with
the 2011 tax year, but the reintroduction was postponed until the 2013 tax year by the Tax Relief,
Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (P.L. 111-312).
The American Taxpayer and Relief Act of 2012 (ATRA; H.R. 8 as enactedP.L. 112-240) restored Pease for tax
years 2013 and beyond. Prior to the enactment of ATRA, Pease’s income thresholds would have
been triggered at $177,550 for single filers for 2013.2022 After the enactment of ATRA, Pease
applies to tax filers with an AGI of:
•
$250,000, if single;
•
$275,000, if head of household;
•
$300,000, if married filing jointly or a surviving spouse; or
15for the 2013 tax year (2014 filing season) with an AGI of
17
IRC §163(h).
Ibid.
1719
The deductions not subject to the Pease limitation are medical and dental expenses, investment interest, qualified
charitable contributions, and casualty and theft losses.
1820
The statutory tax rate is the marginal tax rate a tax filer faces based on their AGI. In contrast, the effective marginal
tax rate is the net rate a taxpayer pays on an increment of income that includes all forms of taxes, including the
different rate for itemized deductions under Pease. The average effective tax rate is calculated by dividing total tax
liability by total gross income.

allow a special exclusion, exemption, or deduction from gross income or which provide a special
credit, a preferential rate of tax, or a deferral of tax liability.”2528 Tax expenditure estimates are
based on current law, which does not assume extensions of temporary provisions that are subject
to expire within the time period observed. Not all tax deductions have JCT tax expenditure
estimates, as some provisions are estimated to result in revenue losses less than $50 million per
fiscal year (JCT’s de minimus level). In addition, some tax deductions are not considered tax
expenditures for various, other reasons.26 For example, the deduction for uncompensated
employee expenses is considered an appropriate measure to adjust a tax filer’s AGI.

Some provisions in the tax code are phased out (i.e., their value is reduced as income rises) for higher-income
taxpayers as a way to target tax benefits on middle- and lower-income households and to limit the loss of revenue.
