Earned Income Tax Credits provide tax reductions and wage supplements for low- and moderate-income working families.  The federal tax system has included an EITC since 1975, with major expansions in 1986, 1990, and 1993, and an additional expansion in 2001.  More than 19 million families and individuals filing federal income tax returns — roughly one out of every seven families who file — claim the federal EITC.

The EITC has been widely praised for its success in supporting work and reducing poverty.  The federal credit now lifts more children out of poverty than any other government program.  Some 4.8 million people, including 2.6 million children, are removed from poverty as a result of the federal EITC.  The federal EITC also has been proven effective in encouraging work among welfare recipients; studies show it has a large impact in inducing more single mothers to work.  Support for the EITC has come from across the political spectrum.

The success of the federal EITC has lead a number of states to enact state Earned Income Tax Credits that supplement the federal credit.


Why Consider a State EITC?

Several developments explain the popularity of state EITCs, including the continued prevalence of poverty among children, the importance under welfare reform of supporting families’ transition from welfare to work, and interest in tax changes that promote tax fairness.

 State EITCs Reduce Poverty Among Children

In 2001, the Census Bureau reported that nearly one child in six still lived in poverty.  Most poor children lived in families with a working parent.

Earned Income Tax Credits can lift families out of poverty by supplementing their wages.

State EITCs Complement Welfare Reform

Although large numbers of welfare recipients have entered the workforce, many cannot make ends meet on their earnings alone.  State EITCs support families who enter and remain in the workforce.

State EITCs Provide Needed Tax Relief during Times of Fiscal Stress

State EITCs also pay a role in shaping state tax systems.  A number of states are responding to weak fiscal conditions by increasing taxes and fees.  Enacting a state EITC is a way to reduce, or at least avoid increasing, the already-substantial burden of state and local taxes on the poor.

Refundable credits:


10% (suspended for 2002; may be suspended for 2003)

Dist. of  Columbia







18% in 2003; 20% thereafter




Varies with earnings; average 33%

New Jersey

20% (if income < $20,000)

New York







4%  —  one child


14%  —  two children


43%  —  three children


Non refundable credits


5% (expires after 2002 unless extended by legislature)







Rhode Island


*Maryland also offers a non-refundable EITC set at 50 percent of the credit.  Taxpayers in effect may claim either the refundable credit or the non-refundable credit, but not both.

Financing a State EITC

The cost of a state EITC depends principally on four factors:  the number of families in a given state that claim the federal credit, the percentage of the federal credit at which the state credit is set, whether the credit is refundable or non-refundable, and how many state residents that receive the federal credit learn about and claim the state credit.  Because state EITCs are well targeted to low- and moderate-income working families, the cost may be relatively modest.  The annual cost of refundable EITCs ranges from about $14 million in Vermont to $423 million in New York. (A relatively straightforward procedure for estimating the cost of a refundable credit in each state is described in a forthcoming paper entitled How Much Would a State EITC Cost?)

How the EITC Works

The federal Earned Income Tax Credit goes only to households with earnings, with the size of the credit initially rising as earnings increase.  The credit is capped at $4,204 for a family with two children and $2,547 for a family with one child; the credit then phases out gradually.  Families with two children may qualify if their incomes are as high as $34,692.  The credit is phased out at a slightly higher income level for married couple families than for other families.  Low-income workers without a qualifying child also may receive a federal EITC, but the maximum credit for individuals or couple without children is $382 in 2003, much lower than the credit for families with children.  The chart above illustrates the structure of the credit for families with children.

 Most state EITCs are structured in the same way as the federal credit except that the amount of credit at each income level is lower.  The table below shows the amount of federal and state credit for families at various income levels.

Center on Budget and Polity Priorities





Most state credits to date have been financed from funds available in a state’s general fund —  the same funding source typically used for other types of tax cuts.  When an EITC is used to offset the effects of a regressive tax increase, as it has been in Indiana and Kansas, such as a sales tax increase, a part of the proceeds of the revenue increase may be set aside for the EITC.  New federal regulations offer the opportunity to finance a portion of the cost of a refundable credit from the federal Temporary Assistance to Needy Families block grant.  Whether general funds or block-grant funds are the most appropriate funding stream to use to finance the credit will depend on a number of factors, including the specifics of a state’s budget situation, the amount of unallocated TANF funds or “maintenance of effort” funds available to the state, and the state’s priorities for use of TANF funds.  No matter how it is financed, however, an EITC can complement a state’s welfare program by assisting low-income working families with children.
