IRS Issues Proposed Regulations to Implement Premium Tax Credit Overhaul
The Internal Revenue Service and the Department of the Treasury have released proposed regulations (REG-101576-26) implementing major updates to the Section 36B Premium Tax Credit (PTC) established under recent statutory changes in H.R. 1, commonly referred to as OBBBA. The proposed rules introduce stricter exchange verification requirements, alter eligibility definitions for certain non-citizen residents, coordinate tax credit eligibility with Medicaid rules, and eliminate longstanding caps on repaying excess advance credit payments.
One of the most consequential changes for individual taxpayers is the removal of repayment limits for excess Advance Premium Tax Credits (APTCs). Under current rules, taxpayers whose actual annual household income exceeds their projected income often benefit from statutory caps that limit the maximum amount of excess advance payments they must repay at tax time. For tax years beginning after December 31, 2025, these protective limits are eliminated. As a concrete practical implication, individuals whose household income fluctuates or increases during the year may face significant unexpected tax bills, as they will be required to repay the entire excess advance credit received. Federal agencies project that approximately 3.7 million tax returns filed in 2028 will report excess APTC repayments under this un-capped framework.
The proposal also tightens verification procedures and reporting standards for health insurance marketplaces. Beginning in tax years after December 31, 2027, a month will generally not qualify for credit coverage unless the exchange officially verifies core eligibility data, including household size, projected income, access to other qualifying coverage, and immigration status. Additionally, for tax years beginning after December 31, 2026, taxpayers must exclude health plan premiums attributable to individuals who are lawfully present but do not meet the amended definition of an eligible alien. Health insurance exchanges will be required to adjust Form 1095-A reporting to exclude non-eligible individuals from reported benchmark premiums.
Another key provision coordinates the premium tax credit with Medicaid community-engagement rules. Under the proposed regulations, individuals who fail to meet Medicaid community-engagement obligations—such as completing at least 80 hours per month of work, educational programs, or community service—will generally still be treated as eligible for Medicaid minimum essential coverage for PTC calculation purposes. Because eligibility for Medicaid coverage disqualifies a taxpayer from claiming health credit subsidies, these individuals will not be permitted to substitute the Premium Tax Credit for lost Medicaid coverage during affected months.
Overall, Treasury and the IRS estimate that these proposed regulations will impact roughly 5.6 million health exchange enrollees out of 13.5 million individuals potentially eligible for the credit. Public comments on the proposed rules remain open through November 30. Taxpayers who receive coverage through public exchanges should closely monitor their projected household income throughout the year to prevent substantial tax reconciliation liability once the statutory repayment caps expire.
