What is an Earned Income Tax Credit?

Earned income tax credit (EITC) is a benefit for working people with low to moderate income that the federal government, many states and some local communities offer.1, 2 It is designed to incentivize work and help reduce poverty, particularly for families with children.1,3 An EITC can act as an additional source of income when the benefit is set up as a refundable credit like the federal EITC and many state EITCs.3, 4 For example, the federal EITC could give a minimum wage worker with two kids up to 40% more income.5, 6

By reducing poverty and increasing income for working families, EITC has been linked to positive health outcomes, particularly for infants and mothers.5, 7-9 Studies show greater health improvements happen when larger, more generous EITC benefits are available.7, 10-11 Health systems and public health partners can reach out to eligible people to raise awareness of and accessibility to the tax credit.

Earned Income Tax Credits (EITCs) can improve health by lifting people out of poverty. In 2018, federal EITCs helped lift about 5.6 million people – half of them children – out of poverty.17

Income Influences Health

There is a well-established relationship between income and health, especially between poverty and poor health.12-14 Income can influence people’s health in a variety of ways:

  • Income can change people’s risk for one or more chronic diseases, like heart disease, diabetes, and stroke.15
  • Many low-income families are unable to afford health insurance and healthcare, and they frequently do not have enough income to live in safe communities with adequate housing and schools. 15
  • In many cases, low-income families do not have access to healthy food, parks or other physical activity facilities, and public transportation—all of which may improve health. 15
  • Financial stress and insecurity that often accompany poverty can negatively affect health. 10, 15

Earned Income Tax Credits Can Improve Health for Mothers and Children

EITC can improve public health by helping to lift people out of poverty. Strong evidence consistently links low income to Adverse Childhood Experience (ACEs) exposures and children’s long-term health, educational, and social outcomes.16

  • In 2018, federal EITC helped lift about 5.6 million people out of poverty – over half of them children . 17
  • EITC has kept more children living above the poverty line than any other tax credit program.18

The existence of a state EITC is connected to a reduction in the low birthweight rate of infants (weight is less than 2500 grams, or about 5 lbs 8 oz). Low birthweight puts babies at risk for death and poor childhood health.19

  • A 2019 study showed 23 states with an EITC saw a connection between EITC and reduction in low birthrate by 4 to 11 percent.10
  • The same study found that states with the greatest reductions in low birthweight rates and greatest increases in birthweight all had refundable tax credits.10

Strong evidence connects low income to poor health and exposure to adverse childhood experiences. Earned Income Tax Credits (EITC) can improve health by providing additional income to working families.

EITC Influences Health and Economic Activity

In addition to positive health changes, earned income tax credits are also linked to increased economic activity at state and local levels.20-21

  • A 2007 analysis of the economic impact of a federal EITC in California found that EITC payments contributed to more than $5 billion in business sales in the state and helped add nearly 30,000 jobs. If all eligible people had claimed their EITCs, their payments would have contributed to another $1.2 billion in business sales and 7,500 jobs.20
