Treasury and the IRS have proposed new rules that would limit the health premium tax credit to U.S. citizens, U.S. nationals and certain lawfully present immigrants, starting in 2027. The IRS announced the proposal on October 14, 2026, in news release IR-2026-121.
The rules are proposed, not final. Nobody gains or loses a credit because of the announcement itself, but the text sets out how the agencies want eligibility and verification to work once the changes take hold.
What did Treasury and the IRS actually propose?
The IRS says Treasury and the IRS issued proposed regulations to carry out what the release calls the Working Families Tax Cuts reforms to the Premium Tax Credit. That credit, often shortened to PTC, helps lower the monthly cost of a plan bought through the health insurance marketplace.
The central change is a limit on who can receive it. Under the proposal, PTC eligibility would be restricted to U.S. citizens, U.S. nationals and certain lawfully present noncitizens. The release says the standards apply beginning in 2027, so subsidies would go only to people who qualify under federal law.
The proposed text is also posted in the Federal Register as document 2026-21056. The IRS page does not give a comment deadline or a date for a final rule.
What do the officials say?
Treasury Secretary Scott Bessent is quoted in the release saying taxpayers “should not be forced to subsidize health care for people who are ineligible under federal law.”
IRS Chief Executive Officer Frank J. Bisignano says the verification measures ensure benefits “go strictly to the hardworking Americans who qualify for them.” Dr. Mehmet Oz, the administrator of the Centers for Medicare and Medicaid Services, says making sure programs “serve only those who are eligible” is among the most effective ways to protect them.

Could this change what a household pays for coverage next year?
The release is aimed at who can receive the credit and at how that is checked. It describes new verification criteria for advance payments of the credit, the monthly amounts sent to insurers during the year to cut premiums.
That matters for anyone who buys marketplace coverage before Medicare starts, including early retirees and spouses under 65. The proposal is not final, so the details can still move, and the IRS page does not walk through every step of the process.
Households that share a plan with a family member who is not a citizen or national should look closely at how that person’s status is treated, since the proposal speaks of “certain” lawfully present noncitizens rather than all of them. The IRS release does not list which groups of noncitizens are covered.
What is the connection to the marketplace enrollment numbers?
The same release points to a separate enforcement effort at CMS. It says the agency removed more than 760,000 unverified enrollees it calls “phantom” enrollees from the Affordable Care Act marketplace, which it says saved $2.2 billion.
The release also says that allowed nearly 1 million Americans to receive $500 each, because they had been overcharged under the prior administration. Those $500 payments are a separate matter from the proposed regulations and do not depend on them.
What comes next?
The IRS says the Department of Health and Human Services is expected to issue parallel proposed regulations. Those would cover the Exchange procedures and operations needed to put the verification requirements in place, which is the part that touches how people actually enroll.
The IRS page does not give a date for a final rule. The government’s enrollment site, HealthCare.gov, is the free official route for checking plan options and what a household’s own premium would be. Anyone on a marketplace plan can compare it there before the new year.
The open question for retirees is not only the credit but the income that feeds into it. Social Security benefits, withdrawals and the new senior deduction all affect the figure a household reports, and that figure drives both the advance credit and the Medicare premium surcharges known as IRMAA. The IRS release does not say those calculations change, but income is the number a household controls most.
Planning your 2027 coverage costs around the proposed credit rules?
If the proposal becomes final, the credit will depend on verified eligibility and on the income a household reports for 2027. A retiree who pulls money from the wrong account first, or misses the senior deduction, can end up reporting more income than needed and paying more for coverage.
The Retirement Tax & Withdrawal Planner covers the senior deduction and the account withdrawal order, and its four calculators (provisional income, IRMAA tier, RMD schedule, Roth bracket fill) show how a withdrawal changes the income figure before it is reported.
