States Can Adopt or Expand Earned Income Tax Credits to Build a Stronger Future Economy
January 19, 2016
Twenty-six states plus the District of Columbia have enacted their own version of the federal Earned Income Tax Credit (EITC) to help working families earning low wages meet basic needs. State EITCs build on the success of the federal credit by keeping people on the job and reducing hardship for working families and children. This important state support also extends the federal EITC’s well-documented long-term positive effects on children, boosting the nation’s future economic prospects.
State EITCs provide extensive benefits to children, families, and communities, and are straightforward to administer and to claim. Lawmakers in states without their own EITC should consider enacting one. States that have cut back or eliminated their credits should reverse course, and states that have limited their credits so that they only offset income taxes should expand them to help offset the full range of state and local taxes that low-income households pay. This would vastly enhance the credits’ impact. By investing in an EITC, states can make a big difference in the lives of low- and moderate-income working families.
Why Consider an EITC?
Many working families with children struggle to make ends meet on low wages. A full-time job at the federal minimum wage yields about $15,000 ― often insufficient income for a family to afford basic necessities. The EITC, a federal tax credit for low- and moderate-income workers and their families, rewards work and improves the outlook for low-income children. State lawmakers can build on the proven effectiveness of the federal EITC to address low wages with a state-level credit. Like the federal EITC, state EITCs:
- Help working families make ends meet. Many low-wage jobs fail to provide sufficient income on which to live. “Refundable” EITCs, which give working households the full value of the credit they earn even if it exceeds their income tax liability, provide low-income workers with a needed income boost that can help them meet basic needs.
- Keep families working. Refundable EITCs help low-wage working families pay for the very things that allow them to continue working, like child care and transportation. They are also structured to encourage the lowest-earning families to work more hours. That extra time and experience in the working world can translate into better opportunities and higher pay over time. Three out of five filers who receive the federal credit use it just temporarily — for just one or two years at a time.
- Reduce poverty, especially among children. Over 10 million children in working families lived below the official poverty line (about $24,000 for a family of four) in 2014; millions of families modestly above that income level have difficulty affording food, housing, and other necessities. The federal EITC is one of the nation’s most effective tools for reducing the struggles of working families and children. It kept 6.2 million people — over half of them children — out of poverty in 2013, and helped many with slightly higher incomes make ends meet. State EITCs build on that record.
- Have a lasting effect. A growing body of research finds that young children in low-income families that get an income boost like the EITC provides tend to do better and go farther in school because the additional resources help parents better meet their needs. And because these children attain more skills and education, they tend to work more and earn more as adults. This helps communities and the economy because it means more people and families are on solid ground and fewer need help over the long haul.
In addition, low- and moderate-income families in almost all states pay higher state and local taxes as a share of their income than do upper-income families (see Figure 1). This imbalance reflects states’ heavy reliance on sales, excise, and property taxes, all of which fall more heavily on low-income families. Some states have increased their reliance on these taxes in recent years by shifting their tax systems away from income taxes, pushing an even larger share of the costs of state services to households earning the least.
More States Building on Federal Credit
In recent years, four states — California (2015), Colorado (2013), Connecticut (2011), and Ohio (2013) — have enacted EITCs to bolster the wages of struggling families, and many other states have improved existing credits.
In 2015, for example:
- Maine expanded its credit by making it refundable;
- Massachusetts raised its credit to 23 percent of the federal EITC from 15 percent;
- New Jersey raised its credit to 30 percent of the federal EITC from 20 percent; and
- Rhode Island raised its credit to 12.5 percent of the federal EITC from 10 percent.
The year prior, Washington, D.C. became the first jurisdiction to expand the credit for workers without dependent children in the home, extending the credit’s reach to childless workers with somewhat higher incomes and setting its value at 100 percent of the federal credit. Also in 2014:
- Iowa raised its credit to 15 percent of the federal EITC from 14 percent;
- Maryland raised its credit to 28 percent of the federal EITC from 25 percent (the increase is scheduled to phase in over four years);
- Minnesota boosted the total value of its credit by 25 percent;
- Ohio doubled its credit to 10 percent of the federal EITC (though it remains nonrefundable); and
- Rhode Island expanded its credit for most recipients by making it fully refundable, though the state also cut the credit to 10 percent of the federal EITC from 25 percent.
In 2013, Oregon expanded its credit to 8 percent of the federal EITC from 6 percent, and Iowa doubled its credit to 14 percent of the federal EITC.
These increases follow several years in which other states cut back or eliminated this support for families earning low wages. In 2013, North Carolina allowed its EITC to end after tax year 2013 and cut it by 10 percent in its final year. In 2011, Michigan cut its credit by 70 percent and Wisconsin cut its credit by 21 percent for families with two or more children. Connecticut, which enacted a credit in 2011 set at 30 percent of the federal EITC, cut it immediately to 25 percent due to budget problems; the credit now stands at 27.5 percent. New Jersey cut its credit to 20 percent of the federal EITC from 25 percent in 2010 but reversed that cut and further increased the credit in 2015.
More than one in three recipients of the federal EITC now lives in a state that has adopted its own EITC, and state EITCs boost the earnings of working families by close to $4 billion annually.
EITC’s Design Rewards Work
The EITC only goes to working families and is designed to reward their effort. For families with very low earnings, the EITC increases as earnings rise, which encourages families to work more hours when possible. Working families with children earning up to about $39,000 to $53,000 (depending on marital status and the number of children in the family) generally can qualify for a state EITC, but the largest benefits go to families with incomes between about $10,000 and $24,000. Workers without children can also qualify in most states, but only if their income is below about $15,000 ($20,000 for a married couple), and the benefit is small.
The EITC’s design also reflects the reality that larger families face higher living expenses than smaller families: the maximum benefit varies for families with one, two, and three or more children. For example, the maximum federal benefit for families with two children in tax year 2015 is $5,548, compared to $3,359 for families with one child. (As with most other federal tax provisions, the IRS adjusts EITC benefit amounts and eligibility levels each year for inflation.) 
Figure 2 shows how the EITC works for a single-mother family with one child earning the minimum wage in 2015 (about $15,000 a year for full-time, year-round work). For every dollar she earns, she gets 34 cents in EITC benefits. The value of the credit continues rising at that rate until her earnings reach $9,880. At that point, she receives the maximum benefit of $3,359. Once her earnings exceed $18,110, the credit shrinks by about 16 cents for each additional dollar of earnings until reaching zero at about $39,000 in earnings.
Most States Model Their EITCs on Federal Credit
Nearly all state EITCs are modeled directly on the federal EITC: they use federal EITC eligibility rules and are a specified percentage of the federal credit. (The percentages are shown in Table 1.)
A few state credits, however, differ somewhat from the federal credit:
- Minnesota uses federal eligibility rules and its credit parallels major elements of the federal structure, but it has its own schedule for the income levels at which the credit phases in and out.
- Indiana uses old federal guidelines that exclude recent expansions and improvements to the federal credit.
- Washington, D.C.’s expanded EITC for workers without dependent children will phase in following federal guidelines, but the maximum credit will extend to 150 percent of the poverty line (for an individual), and the credit will fully phase out at twice the poverty line.
- California’s newly enacted EITC is available to just a small portion of workers who claim the federal credit — those with incomes less than $14,000 for the largest family size — and self-employment income cannot be used to qualify for the credit.
Twenty-three states and Washington, D.C. follow the federal practice of offering a fully refundable EITC. (See Figure 3.) Without this feature, state EITCs would fail to offset the other substantial state and local taxes families pay. It is the reason that the EITC is so effective at boosting income and reducing hardship, because it lets families keep more of what they earn and helps them keep working despite low wages.
The remaining three state EITCs — in Delaware, Ohio, and Virginia — are available only to the extent that they offset a family’s state income tax. Thus, while these non-refundable EITCs can reduce income taxes for families that owe them, they do not make up for other taxes that working families pay; nor do they do much, if anything, to help keep families working and out of poverty. Ohio’s EITC is limited even further, to no more than half of state income taxes owed on taxable income above $20,000.

State EITCs Are Easy to Administer and Less Expensive Than Many Other Tax Cuts
State EITCs are easy to administer and claim. States incur virtually no costs for determining eligibility for their credit because in most cases, families eligible for the federal credit also are eligible for the state credit. And because state credits typically are set at a fixed percentage of the federal credit, state revenue departments need only add one line to a state’s income tax form. State EITCs are easy to claim because filers need only multiply their federal EITC by a specified rate to determine their state credit.
State EITCs also offer a good value to states. Existing refundable EITCs in states with income taxes cost less than 2 percent of state tax revenues each year. Because state EITCs are well targeted to low- and moderate-income working families, the cost is more modest than other tax cuts that states often consider. Though low-income households tend to comprise a substantial share of all taxpayers, they account for a smaller share of tax revenue. A few hundred dollars for each family makes a big difference to the family’s ability to make ends meet without making a major dent in a state’s treasury.
States can also use an EITC to help make low-income families whole again after raising a regressive tax, like the sales tax or gas tax, by setting aside part of the resulting revenue to finance an EITC.
States finance their EITCs in whole or part from their general fund. Federal regulations allow states to finance the refundable part of a credit going to families with children from a state’s share of the federal Temporary Assistance for Needy Families (TANF) block grant. Most states, however, have few such funds, because the value of the TANF block grant ¾ which does not adjust for inflation each year ¾ has eroded over time. No matter how it is financed, an EITC can complement a state’s welfare program by assisting low-income working families with children as they transition from welfare to work.
Even States Without an Income Tax Could Offer a State EITC
Like the federal EITC, state EITCs have a long, successful history of using the income tax to improve the economic security of low-income working families. Some question whether a state with no income tax could offer similar assistance, since state revenue departments in these states do not typically collect the information about family income and structure needed to determine EITC eligibility. The example of Washington State’s Working Families Tax Rebate, however, illustrates how states without an income tax could work with the IRS to provide a state credit.a
To confirm eligibility, Washington State will use data on federal EITC claimants provided by the IRS to state revenue departments under a data-sharing arrangement. Piggybacking on federal efforts saves administrative costs for the state. When the credit is fully phased in, state officials estimate that administration will constitute only about 4 percent of the cost of the EITC.b If the state were to increase the size of the credit, this share would be even smaller.
The other states without a broad-based income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming) could follow Washington State’s lead. State EITCs could be particularly helpful in these states because their tax systems rely heavily on excise taxes, property taxes, and in most cases sales taxes. Because of this reliance, low- and moderate-income families in these states pay a higher share of their income in taxes than wealthier families.
a The Washington State credit was scheduled to take effect in tax year 2009, but — in large part because of the recession and resulting revenue shortfalls — policymakers have not yet financed the credit.
b Fiscal note for Washington ESSB 6809. Note that administrative costs in states that already have an income tax are substantially lower, typically well below 1 percent of the credit’s value.

 According to Census’ Current Population Survey, 10.4 million poor children had at least one working parent in 2014.
 Just prior to the recession, five states enacted new EITCs: Michigan in 2006; North Carolina, Louisiana, and New Mexico in 2007; and Washington State in 2008. Washington State has yet to fund its credit.
 The 2009 Recovery Act included two key provisions to help the EITC go further. First, it expanded “marriage penalty relief” by raising the EITC income eligibility level for married workers by $2,000, thereby extending eligibility for the maximum credit to more married-couple working families with low incomes. Second, it provided, for the first time, a third benefit tier for larger families. Working families with three or more children receive an EITC equal to 45 cents for each dollar earned up to $13,870, for a maximum credit of $6,242 in 2015. The value of the credit completely phases out for single-parent families with three or more children when their income exceeds $47,747 and for married-couple families of this size when their income exceeds $53,267. These expansions were extended in 2012 and made permanent at the end of 2015.
 The California credit is available to working families and individuals with wage income below $7,000 to $14,000, depending on family size. The credit is worth 85 percent of household’s federal EITC until household income reaches half of the level at which the federal credit is fully phased in; it then begins phasing out at varying rates, depending on family size. In 2015, the maximum credit ranges from just over $200 for workers without dependent children to about $2,600 for workers with three or more children. The value of the credit is set each year by the legislature.
 Four factors affect the cost of a state EITC: the number of families that claim the federal credit, the percentage of the federal credit at which the state credit is set, whether the state credit is refundable, and how many state residents who receive the federal credit also claim the state credit.
