Auto-renewal could stop protecting premium tax credits if a new federal proposal becomes final. Under a rule the Centers for Medicare & Medicaid Services floated on October 23, 2026, an Obamacare enrollee who does not return for a yearly eligibility check would still be re-enrolled for 2028, only without the credits that cut the monthly premium. The proposal is not in effect, and the agency labels it CMS-9873-P.
CMS puts it this way: currently enrolled consumers would be re-enrolled with financial assistance only if they return and have their eligibility re-verified. Those who do not come back would be re-enrolled without financial assistance.
The people to watch are the enrollees who have let coverage roll over from year to year without taking any step. If the rule were finalized as written, that habit would carry a price starting with 2028 coverage, and a missed step would show up as a bigger bill rather than a lost plan.

What a skipped check would do to a 2028 plan
The coverage itself would continue. The exchange would roll the enrollee into a plan for the new year, but the advance premium tax credit and any cost-sharing reductions, which lower deductibles and copays, would not be attached. CMS says the eligibility details behind those two forms of help are income, family size, citizenship or immigration status, other coverage and place of residence.
An enrollee who later returns and is verified would have a way back. In the agency’s description, someone verified during a period of mismatched information would receive financial assistance retroactively for those months, and a person who picked a plan pending verification would see enrollment and aid begin once eligibility is confirmed.
When would the yearly check happen?
Under the proposal, the yearly check would run in a window that opens each August 1, with the 2028 plan year the first one it would cover. Exchanges could also mail the annual open enrollment notice before that window opens, rather than in the month before enrollment begins.
That timing matters for a person who normally waits for the fall notice. Under this design, the notice could arrive earlier, and the check it prompts would be the step that decides whether the credits carry into the new year.
What the proposal does not take away
CMS says consumers could still enroll without financial assistance while verifications are pending. The exchange could also keep or reduce aid after an enrollee voluntarily reports a change that affects eligibility, with the new effective date set at the first of the month after the change for an existing enrollee without a special enrollment period.
Certain family changes would not trigger the new proof. Births, adoptions, marriages and the loss of a dependent through divorce, separation or death are covered by a waiver tied to Treasury’s definition of a family size change, and those households would get aid based on what they attested on the application.
Where do states fit in?
A state exchange would feel the change too. Under the proposal, a state would apply to become a state-based exchange 15 months before it starts operations for the verification window, not 15 months before open enrollment. Federal-platform and state-platform enrollments would follow existing binder payment rules, which govern the first premium that starts coverage.
Is anything final yet?
No. Comments run 30 days after the proposal is published in the Federal Register, and CMS has not given a calendar date for that deadline. The agency names no official behind the plan; its media contact is Catherine Howden, director of the CMS News and Media Group. Until a final rule appears, the yearly check, the August 1, 2027 window and the 2028 start are all proposals, and the credits on a renewing 2027 plan are not affected.
Rolling over a Marketplace plan with credits attached?
The detail that is easy to miss in this proposal is the default: an enrollee who does nothing would keep the plan and lose the credits, and other income-based programs that lower household costs also require a deliberate application.
The Benefits Checklist scans 11 benefit programs, with the 2026 income limits and a 50-state phone directory, and the printable application tracker comes with the download. The programs are separate from Marketplace credits, so the kit gives a household a broader look at income-tested help.
