For the millions of people who buy their own health insurance through the Affordable Care Act marketplace, the cost math is changing for 2026 — and not in their favor. The enhanced premium tax credits that had held down monthly costs since 2021 expired at the end of 2025, and their disappearance is pushing up the amount enrollees actually pay. The households feeling it most are people in their late 50s and early 60s, who face the steepest increases at exactly the age when coverage is hardest to go without.
The subsidies that lapsed at the end of 2025
The enhanced ACA premium tax credits were the extra help layered on top of the law’s original subsidies starting in 2021. They worked by capping what enrollees paid for a benchmark plan as a share of their income, which lowered net premiums for millions of people and extended assistance further up the income scale than before. Those enhancements expired at the close of 2025.
With the extra credits gone, the net premium — the figure that actually leaves an enrollee’s bank account after any subsidy — is climbing for 2026, because the mechanism that had been holding it down is no longer in place. The change does not touch the ACA’s core structure; the marketplace, the plans, and the original subsidies all remain. What lapsed was the enhanced layer that made those plans dramatically cheaper for a wide band of buyers. The nonpartisan Kaiser Family Foundation’s Affordable Care Act coverage tracks how the expiration reshapes what enrollees owe.

Why net cost, not sticker price, is the number that matters
It is worth separating two figures that often get blurred. The “premium” an insurer lists is one thing; the amount an enrollee pays after tax credits is another, and it is the second number that hits the household budget. The enhanced credits had lowered that net figure substantially, so their lapse can raise what a family pays even if the underlying sticker premium moves only modestly.
For people who had grown used to a heavily subsidized monthly bill, the jump in net cost is the change to plan around, and for some it will be significant. A household that paid a small fraction of the sticker price under the enhanced credits could find a much larger share landing on them now, even for the same plan. That is why enrollees who glance only at whether the listed premium changed may still be surprised when their own out-of-pocket cost climbs.
Why people 55 to 64 get hit hardest
The increase falls unevenly by age, and near-retirees carry the heaviest load. ACA rules permit insurers to charge older enrollees up to three times what they charge younger ones, so premiums for people aged 55 to 64 start from a higher base. This group is also not yet eligible for Medicare, which does not begin until 65, leaving them dependent on the marketplace during the very years their premiums are steepest.
With the enhanced credits gone, some in this bracket could see their monthly costs rise by hundreds of dollars. It is a squeeze aimed squarely at people close to, but not yet at, the Medicare finish line — often at a stage of life when income may already be tapering as work winds down. For a couple in their early 60s, two premiums rising at once can reshape a retirement-transition budget that had been built around the older, cheaper numbers.
What enrollees can do during open enrollment
The practical response runs through the annual open enrollment period, when enrollees can shop, switch, and re-check their subsidy. Even without the enhancements, the ACA’s original premium tax credits remain, so many households will still qualify for some assistance — just a smaller amount — and it is worth confirming eligibility rather than assuming the help is gone entirely. Comparing metal tiers matters too: moving between bronze, silver, and gold plans trades monthly premium against out-of-pocket costs, and the right balance shifts when subsidies change.
The official place to shop, compare plans, and check eligibility is HealthCare.gov, the government’s marketplace, which walks enrollees through updated pricing and any credit they still qualify for. Running the numbers there matters because a plan that looked affordable under the enhanced credits may now warrant a different choice, whether that means a lower-premium tier, a different insurer, or confirming a still-available credit that softens the increase. For a near-retiree budgeting 2026, the message is to expect a higher net premium and to treat open enrollment as an active decision rather than an auto-renewal, since letting last year’s plan roll over could lock in a cost that no longer makes sense. The larger backdrop — the expiration of the enhanced credits and its outsized effect on the 55-to-64 group — is documented in the Kaiser Family Foundation’s ongoing analysis, which lays out how the change plays through to what enrollees pay.
