The Centers for Medicare & Medicaid Services says it canceled about 315,000 Marketplace enrollments on Aug. 31, 2026, covering more than 760,000 individuals, and expects roughly $2.2 billion in advance premium tax credits to come back to the government. The agency calls the enrollments unauthorized and ties the action to a broader crackdown on insurance agents and brokers. For older adults buying Affordable Care Act coverage before Medicare begins, the episode leaves a concrete tax question: what the return shows for subsidies paid on a policy that was later canceled.
Why 315,000 enrollments and 760,000 people are separate counts
CMS published the figures in a Sept. 22 news release and a companion fact sheet on federal Marketplace anti-fraud actions. The fact sheet says that on Aug. 31 the agency canceled approximately 315,000 enrollments “covering over 760,000 individuals.” The first number counts policies; the second counts the people on them. A single enrollment can include several household members, and the two figures should not be merged into one tally of “760,000 enrollments.”
The $2.2 billion is a different kind of number again. The fact sheet describes it as the expected return of approximately $2.2 billion in advance payments of the premium tax credit tied to the canceled enrollments. It is a CMS estimate, not a collected total. HHS Secretary Robert F. Kennedy, Jr. said in the release that the agency is “shutting down unauthorized Marketplace enrollments and returning approximately $2.2 billion in taxpayer-funded subsidies,” and CMS Administrator Dr. Mehmet Oz said that “every dollar lost to fraud is a dollar taken from hardworking taxpayers.”
A 30-day verification request sat behind the cancellations
The CMS materials describe the canceled enrollments as unauthorized, confirmed through CMS and insurer review. A Morgan Lewis client summary of the action fills in the mechanics: the affected people had enrolled with agent or broker help, without verified citizenship or immigration documentation, and their insurers could not identify claims or establish contact. According to that summary, enrollees received a verification request with a 30-day response window, and coverage was canceled for those who did not respond.
The same summary acknowledges the obvious gap in that design. People who never received the request, or who did not answer in time, lost coverage along with those whose enrollments were truly unauthorized. It also reports that CMS plans to look into a further 440,000 enrollees flagged for irregularities. That count comes from the law firm’s account, not from the CMS pages cited here.
Broker terminations and a registration freeze for 2027
The release puts the agent and broker numbers in plain terms. Since January 2026, CMS has issued termination notices to more than 200 non-compliant agents and brokers. It also sent 569 notices of intent to terminate to those who submitted 2026 applications without Social Security numbers, and the fact sheet says 66 of the first 100 of those notices have already become terminations.
The fact sheet explains why the agency singled out newly registered brokers. Compared with established representatives, the 2026 registrants’ enrollments were 2.8 times more likely to have unresolved income verification issues, 2.7 times more likely to be missing Social Security numbers, and 2.6 times more likely to have unresolved citizenship or immigration status. CMS responded with identity re-verification through Login.gov or ID.me for existing agents and brokers, mandatory Social Security or immigration document numbers for non-newborn applicants, and an electronic consumer authorization requirement coming before open enrollment. Morgan Lewis reports that an interim final rule published Sept. 23 pauses new broker registrations for 2027, expected to last until Feb. 1, 2027 unless lifted or extended.
Form 1095-A and Form 8962 decide what the tax return shows
The money consequence lands at tax time. The IRS explains in its premium tax credit overview, updated Aug. 13, that anyone who received advance payments must file a return and attach Form 8962 to reconcile them against the credit actually allowed, even if the person is usually not required to file. Skipping reconciliation delays a refund and may affect eligibility for future advance payments.
The stakes are higher for 2026 than for earlier years. The IRS questions and answers on the premium tax credit, dated Sept. 21, state that for tax years before 2026 a repayment cap may limit an excess advance payment, while for tax years after 2025 “there is no repayment cap” and the full excess must be repaid. Form 1095-A, the statement the Marketplace sends, supplies the figures for Form 8962. The CMS materials cited here do not say how the canceled months will appear on that form, so the statement itself is the record to compare against actual coverage.
The IRS says it cannot answer questions about the contents of a Form 1095-A or about missing forms, and points people to the Marketplace. HealthCare.gov’s Form 1095-A page lists the Marketplace Call Center at 1-800-318-2596 for incorrect coverage details and advises households not to file taxes until they have an accurate 1095-A.
Medicare drug costs and denials, organized by state
Older adults approaching or already on Medicare often face drug costs and coverage denials that vary by plan, and state help with premiums and prescriptions comes with limits and applications that differ from one state to the next. Keeping those pieces in one place is a separate job from any Marketplace tax question.
The Medicare Cost & Coverage Protection Kit includes a 10-page kit with 51 state Medicare cost-help packs, the prior-authorization appeal steps, and a medication and cost tracker for recording drug costs and denial dates.
