The Potential Long-Run Implications of a Permanently-Expanded Child Tax Credit
The Potential Long-Run Implications of a Permanently-Expanded Child Tax Credit
For many of those who worked to include an expanded Child Tax Credit in the 2021 American Rescue Plan, an important motivation was to test the feasibility and effectiveness of a permanent U.S. child allowance similar to those provided in other rich countries. Because this expansion was short-lived, however, evaluations of its effects cannot provide complete evidence on the long-run effects of a permanently expanded CTC. We leverage theoretical predictions from standard economic models, behavioral science, and child development frameworks, along with empirical evidence from literature evaluating previous long-term cash and quasi-cash transfers to families with children, to predict the likely long-run impacts of a permanent child allowance. We find that it would lead to increased future earnings and tax payments, improved health and longevity, and reduced health care, crime, and child protection costs; using conventional valuations, benefits to society outweigh costs nearly 10 to 1, with most benefits due to credit refundability.
