The amount of income tax owed and tax benefits received at any level of income is determined
by the interaction of the taxpayer’s income and filing status with the other characteristics of the
taxpayer’s family. These figures present the stylized marginal and average tax rates faced by
five typical family types with different incomes. For families with dependents, the amount of tax
support provided to the family due to the presence of that dependent is also shown.
Taxpayers with dependent children pay lower taxes than similar families without children
through the following major tax provisions of the individual income tax:
Filing status – Unmarried taxpayers who are supporting a dependent child may be eligible to
file as a head of household, instead of as a single filer. Head of household status has a higher
standard deduction, and income is taxed under a separate rate bracket structure that is more
generous than the brackets available to single filers.
Child credit (CTC) – Taxpayers may be eligible for a partially refundable child credit of
$2,000 for each child up through age 16 with a valid social security number. In general, the
CTC is non-refundable, but taxpayers with insufficient tax liability to claim the entire CTC
may claim the refundable additional child credit (ACTC), which equals 15% of earned
income greater than $2,500, up to the lesser of (1) the value of the unused portion of the child
credit and (2) $1,400 per child. The CTC (combined with the amount of other dependent
credit [see below]) phases out beginning at $200,000 of modified adjusted gross income
(AGI) ($400,000 for married couples filing a joint return).
Other dependent credit (ODTC) – Taxpayers may be eligible for a non-refundable other
dependent credit of up to $500 for each qualifying dependent relative or child who is not
eligible for the child credit. The ODTC (combined with the amount of CTC [see above])
phases out beginning at $200,000 of modified AGI ($400,000 for married couples filing a
joint return).
Earned income tax credit (EITC) – Taxpayers may be eligible for a refundable EITC. The
amount of EITC a taxpayer may receive initially increases as the taxpayer earns more
income, then remains constant over a range of earned income, and then decreases as earned
income increases further. For families with one child, the maximum credit is $3,526. The
credit begins to phase out at a higher income level for married taxpayers and is more
generous for families with more children (up to three children). Taxpayers without
qualifying children may be eligible for a much smaller EITC.
American opportunity tax credit (AOTC) – Taxpayers with expenses related to their or their
dependent children’s post-secondary education may be eligible for the partially refundable
AOTC of up to $2,500, with up to $1,000 of the credit being refundable. The credit phases
out beginning at $80,000 of modified AGI ($160,000 for joint filers) and is available for 4
years.
Child and dependent care credit (CDCTC) – Taxpayers with expenses for caring for a
qualifying individual, which may be a child or an adult, may be eligible for a non-refundable
CDCTC. The credit is generally available for working taxpayers with dependent children
under age 13, but it is also available for working taxpayers supporting parents or other
dependents needing care. The maximum credit rate is 35% of up to $3,000 of child care
