The Affordable Care Act (ACA) requires insurers to offer plans with reduced deductibles, copayments, and other means of cost sharing to some of the people who purchase plans through the marketplaces established by that legislation. The size of those reductions depends on those people’s income. In turn, insurers receive federal payments arranged by the Secretary of Health and Human Services to cover the costs they incur because of that requirement. At the request of the House Democratic Leader and the House Democratic Whip, the Congressional Budget Office and the staff of the Joint Committee on Taxation (JCT) have estimated the effects of terminating those payments for cost-sharing reductions (CSRs). In particular, the agencies analyzed what would happen under this policy: By the end of this month, it is known that CSR payments will continue through December 2017 but not thereafter.

The Affordable Care Act will make the labor supply, measured as the total compensation paid to workers, 0.86% smaller in 2025 than it would have been in the absence of that law, the Congressional Budget Office estimates. Three-quarters of that decline will occur because of health insurance expansions, which raise effective tax rates on earnings from labor—for instance, by phasing out health insurance subsidies as people’s income rises—and thus reduce the amount of labor that workers choose to supply.
