On the heels of state Earned Income Tax Credit (EITC) expansions in Iowa, Maryland, and Minnesota and heated debates in Illinois and Ohio about their own credit expansions,  the Institute on Taxation and Economic Policy released a new report today, Improving Tax Fairness with a State Earned Income Tax Credit, which shows that expanding or enacting a refundable state EITC is one of the most effective and targeted ways for states to improve tax fairness.

It comes as no surprise to working families that most state’s tax systems are fundamentally unfair.  In fact, most low- and middle-income workers pay more of their income in state and local taxes than the highest income earners. Across the country, the lowest 20 percent of taxpayers pay an average effective state and local tax rate of 11.1 percent, nearly double the 5.6 percent tax rate paid by the top 1 percent of taxpayers.  But taxpayers don’t have to accept this fundamental unfairness and should look to the EITC.

Twenty-five states and the District of Columbia already have some version of a state EITC. Most state EITCs are based on some percentage of the federal EITC. The federal EITC was introduced in 1975 and provides targeted tax reductions to low-income workers to reward work and boost income. By all accounts, the federal EITC has been wildly successful, increasing workforce participation and helping 6.5 million Americans escape poverty in 2012, including 3.3 million children.

As discussed in the ITEP report, state lawmakers can take immediate steps to address the inherent unfairness of their tax code by introducing or expanding a refundable state EITC. For states without an EITC the first step should be to enact this important credit. The report recommends that if states currently have a non-refundable EITC, they should work to pass legislation to make the EITC refundable so that the EITC can work to offset all taxes paid by low income families. Advocates and lawmakers in states with EITCs should look to this report to understand how increasing the current percentage of their credit could help more families.

While it does cost revenue to expand or create a state EITC, such revenue could be raised by repealing tax breaks that benefit the wealthy which in turn would also improve the fairness of state tax systems.
