On April 5, 2022, the Treasury Department and the Internal Revenue Service (IRS) released proposed regulations to address the so-called “family glitch” under the premium tax credit (PTC). The family glitch prevents certain dependents of employees from qualifying for PTC, and by extension for advance payments of PTC and cost-sharing reductions, through the Affordable Care Act’s Marketplaces. Addressing the family glitch is an important step towards making affordable health insurance universally available. While fixing it has long been a key priority of state health officials and other stakeholders, the change will also create new work for states with little time to prepare for its rollout. Marketplaces face operational work to modify application systems and also communications work to reach consumers made newly eligible and explain the new rules and options. This piece reviews the proposed regulations and discusses the potential implications for states.
