What auto-renewal actually does
If you have a Marketplace plan and do nothing during Open Enrollment, you will generally not be dropped. The Marketplace re-enrolls you into your existing plan for the coming year, or, if that plan is no longer offered, into one the system considers similar.
That is genuinely useful. It prevents people from accidentally going uninsured. But it is a floor, not a recommendation, and treating it as a decision is where the cost comes in.
What changes underneath you
Four things routinely change from one plan year to the next, and all four can change without your plan technically being a different plan.
The premium. Carriers reprice every year. A plan that fit your budget can move.
The deductible and out-of-pocket maximum. These are reset and often adjusted upward. The same plan can ask you to spend more before it pays.
The provider network. This is the one that causes the most damage. Hospitals and physician groups join and leave carrier networks every year. A plan you have held for three years can quietly stop covering the specialist you have seen for all three.
The drug list. Formularies change. A medication that was covered at a low tier can move to a higher tier, require prior authorization, or come off the list entirely.
None of these generate a phone call to you. They arrive in a notice, and the notice looks like every other piece of insurance mail.
The subsidy problem
This is the part people are least aware of.
Your premium tax credit is based on the income you expect to earn and the size of your household. If you do nothing, the Marketplace carries forward the information it already has.
If your income changed — you earned more, earned less, changed jobs, started working for yourself, had a child, got married — the subsidy being applied to your January premium may be based on a picture that is no longer true. Too little subsidy means you overpay all year. Too much means you may owe some of it back when you file.
Updating your income estimate takes a few minutes and is the highest-value part of the review. Our explanation of how ACA subsidies work covers what the Marketplace is asking for and why it matters.
The number that decides your subsidy
Premium tax credits for 2027 coverage are available to households earning between 100% and 400% of the federal poverty level. Above 400%, the credit is zero. Not reduced — zero.
The Marketplace uses the prior year's poverty guidelines, so 2027 eligibility is measured against the 2026 table. For the 48 contiguous states and DC, the 400% line works out to:
| Household size | 400% of poverty (2027 cliff) |
|---|---|
| 1 person | $63,840 |
| 2 people | $86,560 |
| 3 people | $109,280 |
| 4 people | $132,000 |
| 5 people | $154,720 |
A family of four in North Carolina expecting $131,000 qualifies for help. The same family expecting $133,000 does not. That is a real edge, and it is worth knowing where it sits before you file an income estimate.
This matters more than it used to. Between 2021 and 2025, enhanced subsidies removed the upper limit entirely and capped premiums at a percentage of income no matter how much you earned. Those enhanced subsidies expired January 1, 2026. The original cliff is back, and households who were comfortably covered two years ago may now be over the line.
Be aware that a good deal of material still online describes the 8.5% cap and no upper limit. Some of it sits on government pages that were never updated. For 2027 coverage it is wrong.
Why this matters more for 2027
Open Enrollment for 2027 runs November 1 through December 15, and the January window that used to exist is gone. That means fewer weeks to notice a change and fix it.
The practical effect is that auto-renewal will catch more people this year — not because they chose it, but because they ran out of time. The details are in what shortened the 2027 enrollment window.
What to check, in order
A proper review takes about twenty minutes if you do it in this order.
- Find your renewal notice. Your carrier sends one each fall. It shows next year's premium, deductible, and any plan changes. It is the most useful document you will receive.
- Check your doctors. Confirm each one you want to keep is in network for next year, not this year. Networks are listed by plan year.
- Check your prescriptions. Look up each medication on next year's drug list and note the tier.
- Update your income. Estimate 2027, not 2025.
- Then compare. Only after the first four does comparing plans mean anything, because now you know what you are comparing against.
When staying put is the right answer
Often it is. If your premium is stable, your doctors are still in network, your medications are still covered at the same tier, and your income has not moved, then letting the plan renew is a perfectly good decision.
The difference is that you will have made it on purpose. That is the entire point of the review — not to switch, but to know.
What happens if your plan is discontinued
Sometimes the plan you have simply will not exist next year. Carriers withdraw plans, restructure them, or leave a county entirely.
When that happens, the Marketplace generally maps you to what it considers the closest available plan from the same carrier, or from another carrier if yours left. That mapping is automated. It looks at plan category and structure, not at whether your oncologist is in the new network or whether your insulin is on the new formulary.
A discontinued plan is the strongest possible signal that you should review rather than let the system choose. Your renewal notice will say clearly if this applies to you.
The quiet cost of doing nothing
It is worth being concrete about how auto-renewal actually costs money, because it rarely shows up as one big number.
It shows up as a premium that is forty dollars higher than a comparable plan you did not know existed. As a deductible that rose while a competing plan's did not. As a specialist visit that is suddenly out of network and billed at a rate you did not expect. As a medication that moved a tier and now costs four times what it did in December.
Individually none of these is dramatic. Across a year, for a household managing an ongoing condition, they add up to real money — and every one of them was visible in October.
If you have had the same plan for years
Long tenure feels like stability and is often the opposite. The longer you have held a plan without reviewing it, the more accumulated drift there is between what you bought and what you now have.
Carriers also tend to introduce newer plan designs over time, and older plans can become what the industry calls closed blocks — still active, still billed, but no longer competitively priced because no new members are joining them.
If it has been three or more years since you compared, that is the strongest case for spending twenty minutes this November.
How The Jordan Insurance Agency helps
Checking a network and a drug list across every plan available in your county is tedious, and it is exactly the kind of work an agency does quickly because we do it all day.
The Jordan Insurance Agency is an independent agency in Charlotte, North Carolina. We will pull your current plan, compare it against what is available for next year, and tell you plainly whether staying or switching serves you better. If staying is right, we will say so.
There is no charge. Carriers pay the agent, so your premium is the same whether you review it with us or let it renew on its own. If you would rather not spend a December evening cross-referencing formularies, that is what we are for. Some people prefer to handle it themselves, and we have written fairly about using an agent versus enrolling on HealthCare.gov.
