• Everyone pays taxes
(either directly or indirectly).
• There are explicit
progressive/redistributive properties in
the tax system.
• There are high-quality tax data.
• There is a lot of theoretical work on tax
incidence in the economics literature.
Why?
Distributional Analyses Have
Historically Been Tax-Centric

But there’s more to government than just taxes.
Our goal is to use a framework that allows for
the analysis of the distributional effects of
government transfers while dealing with the
effects of large intergenerational transfer
programs in cross-sectional analyses of
household income.

CBO’s Current Distributional Framework
Strengths Shortcomings
• Before-tax income, a broad
income measure, is a proxy
for both overall economic
well-being and ability to pay
tax liabilities.
• Before-tax income is
therefore an appropriate
denominator for calculating
average tax rates.
• Because before-tax income
includes government
transfers, retired households
are relatively evenly spread
among before-tax income
groups.
• The framework is tax-centric,
so it doesn’t allow for
analysis of government
transfers—that is, analysts
cannot calculate meaningful
transfer rates or net tax and
transfer rates.
• Therefore, the redistributive
properties of transfers and
taxes are not treated equally.

Market Income Distributional Framework
Strengths Shortcomings
• Market income is an intuitive
measure of pre-government
income.
• The framework lets analysts
calculate transfer rates, tax
rates, and net tax and
transfer rates.
• “Market income” suggests no
government intervention,
but the measure includes the
effects of other, less direct
governmental policies.
• Market income is not a good
proxy for overall economic
well-being and ability to pay
tax liabilities.
• Life-cycle patterns in market
income make retired people
appear poor in cross-
sectional analyses.

After-Tax Income Distributional Framework
Strengths Shortcomings
• After-tax income is a proxy
for overall economic well-
being.
• It can be used as a
benchmark for how income
inequality is changing over
time regardless of source
(market income, transfers, or
taxes).
• After-tax income is not an
appropriate denominator for
calculating tax or transfer
rates because taxes and
transfers are included in it.

Gross Income Distributional Framework
Strengths Shortcomings
• The framework allows
analysts to calculate means-
tested transfer rates, tax
rates, and net tax and
transfer rates.
• It accounts for life-cycle
income patterns caused by
the receipt of social
insurance benefits.
• Gross income does not fully
represent people’s ability to
pay their tax liabilities.
• There is some redistribution
in social insurance programs
that the framework does not
capture.
• Social insurance benefits and
the taxes that finance them
are not treated equally.
• Not including public goods
results in an incomplete fiscal
picture when calculating net
tax and transfer rates.

Using a before-tax income framework
produces different distributional results
depending on whether the policy is
implemented as a refundable tax credit or a
means-tested transfer, even though they are
economically identical policies.
Using a gross income framework, however,
produces identical distributional results.
35CONGRESSIONAL BUDGET OFFICE
Notes
Market income consists of labor income, business income, capital gains (profits realized from
the sale of assets), capital income excluding capital gains, income received in retirement for
past services, and other sources of income.
Government transfers are cash payments and in-kind benefits from social insurance and other
government assistance programs. Those transfers include payments and benefits from federal,
state, and local governments.
Before-tax income is market income plus government transfers.
Social insurance transfers are Social Security benefits for workers, spouses, survivors, and
the disabled; Medicare payments; and unemployment insurance benefits.
Gross income is market income plus social insurance transfers.
Means-tested transfers include payments and benefits from Medicaid; the Supplemental
Nutrition Assistance Program, or SNAP (formerly Food Stamps); housing assistance programs;
and several smaller programs.
Federal taxes include individual income taxes, payroll taxes, corporate income taxes, and
excise taxes.
After-tax income is before-tax income minus federal taxes.
Income groups are created by ranking households by various income measures, adjusted for
household size.
Quintiles (fifths) contain equal numbers of people.
