The Earned Income Tax Credit (EITC) is a refundable federal tax credit aimed at low- and moderate-income working households. It phases in with earnings, plateaus, and phases out, with the largest benefits going to workers with children. Childless workers currently receive a much smaller credit and a narrower eligibility range.
Both Republican and Democratic administrations have historically expanded the EITC, citing its work-incentive structure and bipartisan economic literature on its anti-poverty effects. Recent proposals would substantially raise the maximum credit for childless workers, lower the minimum age, and raise income thresholds.
Critics of expansion raise concerns about administrative complexity, error rates, marriage penalties at certain income levels, and whether the credit is the best mechanism compared to wage policy or direct cash benefits.
