NEW YORK, October 16, 2026 – Federal tax regulators are taking a hard line on health care subsidy fraud.
Proposed rules regarding the Premium Tax Credit were released by the U.S. Department of the Treasury and the IRS on October 14, 2026. These rules are intended to prevent any inappropriate claim for the premium tax credit and have been introduced within the framework of the Working Families Tax Cuts.
Billions in taxpayer dollars hang in the balance as the administration builds its rationale for the overhaul.
The revised eligibility requirements, as per the latest updates from the Department of the Treasury, include that only U.S. citizens, U.S. nationals and specific categories of lawfully present non-citizens qualify for the advance payment of the Premium Tax Credit. It is expected that the Department of Health and Human Services will release related operation rules for state and federal marketplaces shortly.
Here’s the practical problem. Under covert testing carried out by the Government Accountability Office, systemic failures were found in federal exchange screening. Fake applications for subsidized coverage for 2024 and 2025 were sent to the federal system screeners using fictitious identities. All but one of the 24 test applications got accepted. While the report shows very clearly the weaknesses, the exact dollar figure of exchange fraud has not been calculated.
Treasury Secretary Scott Bessent put the issue right in the open by saying, “Taxpayers cannot be made to pay the costs of insurance for people that do not meet the requirements of the federal government.” In a similar vein, Frank J. Bisignano, the Chief Executive Officer at IRS, said that it was necessary to step up verification because only then can “the important tax benefits” reach the eligible Americans. Furthermore, Dr. Mehmet Oz, Centers for Medicare & Medicaid Services Administrator, said that “prevention is better than a pound of cure,” referring to the recently stripped 760,000 “phantom” members.
According to reports from industry tracking services like CPA Practice Advisor, these numbers will provide an ammunition in the policy dispute to follow. While the advocates feel they justify tightening verification requirements, some critics fear the process might end up creating a bureaucratic web for the legitimate low-income Americans.
So what happens next?
The rules remain open for public comment, and full operational implementation won’t take effect until tax year 2027. For over 19 million Americans enrolled in marketplace plans, the credit itself stays intact, but proving eligibility is about to get much tougher.
