Marriage Tax Penalty Relief Provisions of the
Economic Growth and Tax Relief
Reconciliation Act of 2001

Specialist in Public Finance
Government and Finance Division
Summary
The Economic Growth and Tax Relief Reconciliation Act of 2001 contains three
marriage tax penalty relief provisions. It increases the standard deduction for joint
returns to twice the size of the standard deduction for single returns. This change is
phased in over a five-year period starting in calendar year 2005. The 2001 Act also
increases the width of the 15% marginal income tax bracket for joint returns to twice
the width of the 15% tax bracket for single returns. This change is phased in over a
four-year period starting in calendar year 2005. Finally, the 2001 Act increases the
earned income tax credit phaseout start and end points for joint returns by $3,000 with
the increase phased in over a seven-year period starting in calendar year 2002. The
Joint Committee on Taxation estimates that the combined cost of all of the marriage
penalty relief provisions will be $63 billion over the fiscal year period 2002 through
2011. As with the 2001 Act’s other tax changes, however, these changes affecting the
marriage neutrality of the federal income tax are scheduled to expire after 2010.
On May 21, 2002, the House approved the Encouraging Work and Supporting
Marriage Act of 2002 (H.R. 4626). This Act would increase the basic standard
deduction for married couples filing joint returns to 170% of the amount of the
deduction for single filers in 2003 and 2004.
During the week of June 10, 2002, the House is scheduled to consider H.R. 4019,
a bill that would make the marriage tax provisions of the Economic Growth and Tax
Relief Reconciliation Act of 2001 permanent.

This report will be updated as legislative action warrants.

Background
Defining the married couple as a single tax unit under the federal individual income
tax tends to violate the goal of marriage neutrality. Marriage neutrality means that the
tax system should not influence the choice of individuals with regard to their marital
status. However, under the current federal income tax system, some married couples pay
more income tax than they would as two unmarried singles (a marriage tax penalty) while
other married couples pay less income tax than they would as two unmarried singles (a
marriage tax bonus).
The three most important structural features affecting the marriage neutrality of the
income tax are the earned income tax credit (EIC), the standard deduction, and the tax
rate schedules. Under the current income tax system, single individuals, heads of
households, and married couples are subject to different standard deductions and tax rate
schedules. The EIC amounts and phaseout ranges also vary according to filing status.
These differences give rise to structural marriage tax penalties and bonuses.
Because of these asymmetries, when the income of one spouse is added to the
income of the other spouse, a married couple might find themselves paying either more
federal income tax (a marriage penalty) or less tax (a marriage bonus) than they would
by filing as two singles. Two singles (or some combination of singles and heads of
households) contemplating marriage might find that their federal income tax liability
increases (a marriage tax penalty) or decreases (a marriage tax bonus) by filing a joint
return.
In general, the division of income, or income split, of the two individuals determines
whether they will have a marriage tax bonus or penalty. The largest marriage tax bonuses
occur when one spouse earns 100% of the income. The more evenly divided the income,
the more likely a married couple will experience a marriage tax penalty. The largest tax
penalties occur where the income is evenly divided between the two spouses, a 50/50
income split.
For example, consider the case of two married couples where each couple has
$60,000 of income. One couple is a one-earner household where one spouse earns all the
income while the other couple is a two-earner household where each spouse earns
$30,000. Under the federal income tax rate structure in effect in 2001, the one-earner
couple has a marriage tax bonus of $4,326 (that is, they pay $4,326 less filing a joint
return than they would if they filed as two single individuals) while the two-earner couple
has a marriage tax penalty of $406 (that is, they pay $406 more filing a joint return then
they would if they filed as two single individuals).
Eliminating marriage tax penalties and bonuses and creating a marriage neutral
income tax are elusive equity goals. Marriage neutrality conflicts with two other
concepts of equity: progressivity and equal taxation of couples with equal incomes.
Regardless of how these three concepts of equity are juggled, an income tax can achieve
any two of these goals but cannot, under current definitions, simultaneously achieve all
three.

Over time, Congress has switched emphasis among these three equity goals of
marriage neutrality, progressivity, and equal taxation of couples with equal incomes.1
The changes in the 2001 Act, which are described below, will provide a tax reduction to
all married couples filing a joint return regardless of whether or not they currently incur
a marriage tax penalty. Married couples who currently experience a marriage tax bonus
(they pay less filing a joint return than they would filing two single returns) will see their
bonus increase. Married couples who currently experience a marriage tax penalty will
see their marriage tax penalty reduced or eliminated.
The 2001 Act
The Economic Growth and Tax Relief Reconciliation Act of 2001 (H.R. 1836) was
approved by both chambers of Congress on May 26, 2001 and signed by President
George W. Bush on June 7, 2001 (P.L. 107-16). The Act contains three provisions
designed to reduce marriage tax penalties.
First, the Act increases the standard deduction for joint returns to twice the amount
of the standard deduction for single returns. (The standard deduction for joint returns is
currently equal to 167% of the standard deduction for single returns.) This change is
phased in over a five-year period starting in calendar year 2005. The Joint Committee
on Taxation (JCT) estimates that this change will reduce federal income tax revenues by
approximately $15 billion over the fiscal year period 2005 through 2011. Table 1 shows
how the change will be implemented.

Second, the 2001 Act increases the width of the 15% marginal income tax bracket
for joint returns to twice the width of the 15% marginal income tax bracket for single
returns. (The 15% tax bracket for joint returns is currently 167% of the width of the 15%
tax bracket for single returns.) This change is phased in over a four-year period starting

in calendar year 2005. The JCT estimates that this change will reduce federal income tax
revenue by approximately $33 billion over the fiscal year period 2005 through 2011.
Table 2 shows how this change will be implemented.

Third, the 2001 Act increases the earned income tax credit phaseout start and end
points for joint returns by $3,000, with the increase phased in over a seven-year period
starting in calendar year 2002. The $3,000 amount will be adjusted on an annual basis
for inflation beginning after 2008.2 The JCT estimates that this provision will reduce
federal income tax revenues by $15.6 billion over the fiscal year period 2002 through
2011. Table 3 shows the schedule for the increase in the phaseout start point for the EIC
for taxpayers filing joint returns.

provisions will be $63 billion over the fiscal year period 2002 through 2011. All of the

compensation from the calculation of earned income and repeals the income tax provisions that
reduce a taxpayer’s EIC by the amount of their alternative minimum tax. For more information

Amounts, by Melinda Gish.

however, will expire after calendar 2010. This sunset provision was included in the Act
to meet the requirements of Senate procedural rules on budget reconciliation.
