Benefits cliff refers to a situation in which a relatively small increase in an individual’s or family’s income results in a significant reduction or loss of public benefits, leaving the household financially no better off—or sometimes worse off—despite earning more. Benefits cliffs can occur when increased earnings from a raise, promotion, additional work hours, or a new job cause household income to exceed eligibility thresholds for programs such as childcare assistance, health coverage, food assistance, housing assistance, or other income-based supports. If the value of the benefits lost exceeds the additional earnings, advancing in the workforce can result in a net financial loss. Benefits cliffs can create barriers to economic mobility by forcing workers and families to weigh career advancement against the potential loss of supports that help cover essential expenses. The issue is especially significant when benefits end abruptly at a specific income threshold rather than gradually decreasing as earnings rise.

A related concept, a benefits plateau, occurs when rising earnings are largely offset by reductions in public benefits, taxes, or increased household expenses. In these situations, workers may earn more without experiencing a meaningful increase in their available financial resources.

Benefit cliffs are not simply a public-benefits policy issue. They are also a workforce advancement and employer issue. A worker may rationally decline overtime, a raise, additional hours, or a promotion if accepting it would leave the household worse off. That connects the term directly to economic mobility, job quality, career advancement, employee retention, and workforce policy.
