The Earned Income Tax Credit (EITC) is a refundable income tax credit for low to moderate income working individuals and families. EITCs are offered by the federal government and many state governments. Federal earned income limits vary based on family size. The value of the EITC changes yearly; for the 2017 tax year, an individual with no custodial children who earns less than $15,010 can receive up to $510, while a married couple with three or more children making less than $53,930 qualify to receive up to $6,318. States that offer EITCs have various eligibility rules; similar to the federal EITC, refund amounts vary by income1.

Evidence of Effectiveness

There is strong evidence that the Earned Income Tax Credit (EITC) increases employment and income for participating families2, 3, 4, 5, 6, 7, 8, 9 and improves birth outcomes4, 10, 11, 12.

The EITC increases employment for single-parent households through increases in both labor force participation and hours worked13, especially in households headed by mothers4, 5, 7, 8, 9, 14, 15. However, it may not increase labor force participation for married couples with very low incomes, especially those who would lose eligibility for an EITC refund if income increased6, 7. The EITC can also decrease labor force participation and hours worked among married mothers3, 6, 7. It has demonstrated no impact, positive or negative, on the likelihood that men work or the number of hours they work3. While families in large cities are the most likely to earn the credit16, 17, the EITC is also a substantial source of income support in rural areas13, 16, 18.

Availability of a generous EITC when women have young children may, in the long-term, increase earnings and hours worked for single women but decrease earnings and hours worked for married women2. Refundable EITCs may increase financial stability for single mothers with low incomes through increases in earnings, savings, and reductions in unsecured debt19. In times of high unemployment, the EITC may provide an income cushion for skilled workers and married couples but does not appear to provide the same benefit to single parents with children20. An early assessment of the Paycheck Plus program, an EITC-like program for workers without dependent children, suggests that expanding the amount of the credit has the potential to increase earnings, employment, tax filing, and child support payments21.

Receipt of the EITC decreases the incidence of low birthweight births4, 10, 11, particularly among black mothers12. Effects may be larger with more generous EITCs10. EITC receipt is associated with improved maternal22 and child health23, 24, including reduced infant mortality24 and increased breastfeeding rates11. Expansions of state EITCs may improve the health of children ages 6-14, and support transitions from public to private health insurance25. A study of the 1990 expansion of the federal EITC suggests increasing the EITC may improve mental health for mothers who are married26. State level EITCs may reduce recidivism among women27.

Increasing family income through employment and earnings supplements has been shown to have positive effects on children, most consistently on school achievement among elementary school students28. Receipt of the EITC may also reduce children’s problem behaviors29. EITC expansion may improve the quality of home environments23 and decrease children’s entry into foster care30. The EITC may reduce child neglect in disadvantaged families31. A study of state level refundable EITCs suggest it may decrease abusive head trauma in children under 2 years old32. Recent studies suggest that increases in the EITC are associated with reductions in new marriages but have no impact on divorce rates33. Single mothers are less likely to marry and more likely to cohabit if marriage will lead to the loss of EITC benefits, particularly mothers with lower incomes, who have never been married, or are racial minorities34.

The EITC appears to reduce poverty, with the largest effects among single parent families14, 35 and those nearest the poverty line14. A 2015 report projects that increasing the federal EITC for lower income families with children would reduce child poverty by 9% (1 million children). This increase would cost approximately $8.2 billion. Expanding state and local EITCs is also likely to reduce child poverty36. State EITC supplements appear to be cost-effective, increasing quality of life and longevity among recipients37.

The EITC is often used to meet short- and medium-term needs17. Research suggests that recipients generally use EITC refunds to meet basic needs, repair vehicles13, 38, and repay debt13, 38, 39. Some recipients also use it to obtain additional education or training38.

EITCs may have a positive impact on state and local economies through increased sales and jobs40. Efforts to increase awareness of the EITC, such as direct mailings, may increase take up41.

Implementation Examples

As of 2018, 29 states and Washington DC offer an Earned Income Tax Credit (EITC) that is a percentage of the federal credit; 24 are refundable42. In 2016, more than 26 million families received the EITC43; however, about 20% of eligible workers did not claim the EITC1.

The state of New York and Washington DC have noncustodial parent EITCs for those who work and pay full child support44. New York’s noncustodial parent EITC appears to have increased employment among non-custodial parents as well as the percentage of noncustodial parents paying child support in full45.

The Volunteer Income Tax Assistance (VITA) program provides free tax preparation for people with low incomes, those with disabilities, and those with limited English proficiency across the country, which includes helping tax filers claim the EITC46. Innovative programs to increase EITC uptake include Boston Medical Center’s StreetCred, which is embedded in pediatric primary clinics47.
