Auto-Renewal 2026 to 2027: Why You Should NOT Trust It and How to Re-Shop

Auto-renewal 2026 to 2027 is risky: IRA fully expired, 400% FPL cliff back, DACA APTC rollback, network changes. Why active re-shopping during OEP matters.

Quick estimate: see what you might pay with our subsidy calculator before you read on.

Auto-renewal is the Marketplace’s default. If you have an ACA plan in 2026 and you do nothing during Open Enrollment, the Marketplace will roll you into a 2027 plan automatically. For most years that has been a reasonable fallback. For the 2026 to 2027 transition, it is the most expensive autopilot you can leave on.

Four things shifted at once heading into 2027. The Inflation Reduction Act subsidies are fully expired. The 400 percent of Federal Poverty Level subsidy cliff is back. The DACA APTC rollback closed a window for many DACA recipients on June 30, 2026. And insurer networks moved during 2026 in ways that the auto-renewal notice will not flag. This page walks through what auto-renewal actually does, why 2027 is structurally different, what notices to expect, and exactly what to do instead.

What auto-renewal actually does

Auto-renewal is the Marketplace’s passive enrollment process. If you do not log in, compare plans, or actively choose a 2027 option by December 15, 2026, the system carries your enrollment forward. You stay in the same plan if your carrier still offers it for 2027. If your plan was discontinued, the Marketplace maps you to a similar plan from the same carrier, or to a similar plan from a different carrier in the same metal tier. Your reported income, household size, and immigration attestation carry forward. Your subsidy gets recalculated against the 2027 benchmark Silver plan in your county using last year’s income figure.

Coverage starts January 1, 2027. ID cards arrive in late December or early January. The first 2027 premium is due to your carrier on whatever schedule your prior plan used.

What auto-renewal does not do: it does not refresh your income, it does not flag network changes, it does not flag formulary changes, it does not flag whether a different plan would now cost you less, and it does not warn you if you are about to fall over the 400 percent FPL subsidy cliff. The Marketplace assumes you reviewed everything yourself. That assumption is wrong about 70 percent of the time, based on prior CMS data on net premium movement under passive renewal.

Why the 2026 to 2027 transition is different

Four forces converge on the 2027 plan year.

The IRA enhanced subsidies are fully expired. The Inflation Reduction Act enhanced premium tax credits from 2021 through 2025. Those credits expired on December 31, 2025. The 2026 plan year was the first year of partial impact, but 2026 rates were filed before carriers had real enrollment data under the new rules. The 2027 rates filed in mid-2026 reflect a full year of enrollment behavior, medical loss ratios, and risk-pool adjustments under the post-IRA structure. The pricing reset for 2027 is therefore deeper and more uniform than the partial reset for 2026.

The 400 percent FPL subsidy cliff is back in full effect. Before the IRA, any household with projected income above 400 percent of the Federal Poverty Level lost the Advance Premium Tax Credit entirely. The IRA replaced that hard cliff with a smooth cap that nobody pays more than 8.5 percent of household income for the benchmark Silver plan. With the IRA expired, the original cliff is back. For 2027, a family of four projecting income above roughly 124,800 dollars hits the cliff and pays the full unsubsidized premium. Auto-renewal does not warn you about this. It carries your old income forward and your old subsidy keeps showing up on your invoice. The reconciliation at tax filing time recovers any overpaid credit.

The DACA APTC rollback closed eligibility for many recipients on June 30, 2026. A federal rule briefly opened ACA Marketplace plans and premium tax credits to DACA recipients starting in November 2024. A court ruling effective June 30, 2026 rolled back APTC eligibility for DACA recipients with household incomes above 138 percent of the Federal Poverty Level. DACA recipients who were auto-enrolled before that date with a subsidy may find that the 2027 auto-renewal preserves a subsidy they no longer qualify for. The cleanest move for any DACA household is to confirm current eligibility with a licensed agent before relying on the HealthCare.gov estimate.

Insurer networks shifted during 2026. Several large carriers narrowed their provider networks during 2026 in response to medical cost pressure. Hospital systems exited contracts, specialists moved between networks, and pharmacy networks tightened. None of those changes show up in the auto-renewal notice. Your auto-renewed plan in January 2027 may have the same name as your 2026 plan but a different set of in-network doctors.

The auto-renewal timeline

The cadence of notices and deadlines for the 2026 to 2027 cycle:

  • October to early November 2026: your insurance carrier mails a renewal notice with your 2027 monthly premium, plan changes, formulary changes, and network changes. Read it carefully.
  • Mid-November 2026: the Marketplace mails or emails a separate notice confirming whether your plan continues, whether you are slated for auto-renewal, and what your projected 2027 premium tax credit looks like based on your last reported income.
  • November 1, 2026: Open Enrollment opens. You can log in, update your income, compare plans, and actively re-select.
  • December 15, 2026: deadline to actively re-shop and lock in January 1, 2027 coverage. If you take no action by this date, auto-renewal processes overnight.
  • December 16, 2026 to January 15, 2027: federal Open Enrollment continues. You can still change your auto-renewed plan, but the new plan starts February 1.
  • January 16, 2027 to January 31, 2027: most state Marketplaces extend Open Enrollment. New plans selected during this window start March 1.

If you receive your carrier notice in October and your premium jumped, do not wait until December to react. Log in to the Marketplace the first week of November and run a fresh comparison.

The real risk of doing nothing

Five concrete risks ride along with passive auto-renewal for 2027.

Risk one: the auto-renewed plan is not the right plan for your 2027 situation. If your income changed in 2026, if your household changed, if your prescriptions changed, or if your providers changed, the plan that fit you in 2026 may no longer fit. The Marketplace will not catch any of this on your behalf.

Risk two: your doctor is no longer in network. A 2027 plan with the same name as your 2026 plan can drop a hospital system, a specialist group, or a pharmacy chain. You find out in February when you try to schedule an appointment.

Risk three: your carrier exited the market. When a carrier exits, the Marketplace maps you into a similar plan from a different carrier. The mapping may not match your usage. The new plan’s network, formulary, and out-of-pocket structure can be substantially different.

Risk four: a better plan is now available at a lower premium. Plans launch and close every year. The 2027 market in your county includes new offerings the Marketplace will not surface unless you actively shop.

Risk five: APTC recalculation produces a surprise. The Marketplace recalculates your subsidy against the 2027 benchmark Silver plan in your county. If the benchmark moved, your subsidy moves. If your income changed and you did not report it, your auto-renewed subsidy is overstated and you will owe the difference at tax time.

What to do instead

Re-shop actively. The exercise takes 30 to 60 minutes if you prepare ahead, and the structure is the same every year.

  1. Receive both notices. Look for the carrier notice in October or early November and the Marketplace notice in mid-November. If you have not seen either by November 20, log in to your carrier portal and your Marketplace account to pull them down directly.
  2. Update your 2027 income projection. Open your Marketplace account between November 1 and December 1. Enter your best estimate of 2027 household income, not 2026 actuals. Include all sources: wages, self-employment, rental, investment, child support, Social Security disability, unemployment.
  3. Pull your list of doctors and prescriptions. Write down every provider you saw in 2026 and every medication you take regularly. Note dose and frequency for each prescription.
  4. Compare 2027 plans in your area. Use the Marketplace shopping tool to pull a side-by-side view. Sort by total expected cost, not just premium. Look at deductible, out-of-pocket maximum, and copay structure together.
  5. Confirm networks plan by plan. For each plan you are considering, look up each of your providers in the carrier’s 2027 directory. The Marketplace network lookup is less reliable than the carrier’s own directory.
  6. Check the formulary for each prescription. Confirm the medication is covered and the tier has not changed.
  7. Choose actively, even if you end up with the same plan. Active re-selection logs your review with the Marketplace and recalculates your subsidy against your current income and the current benchmark.

Common mistakes during the 2026 to 2027 transition

Assuming “same plan” means the same coverage. A 2027 plan with the same name as your 2026 plan can have a different network, a different formulary, a different deductible, and a different out-of-pocket maximum. The plan name is a label, not a contract.

Not updating income. The Marketplace carries forward whatever income figure you last reported. If your income changed in 2026 and you did not report it, your 2027 subsidy is wrong from day one.

Ignoring the 400 percent FPL cliff. Households projecting income above the cliff need to actively check their eligibility for 2027. Auto-renewal will not catch the cliff and the reconciliation at tax filing recovers any overpaid credit.

Trusting the auto-renewal notice as a full comparison. The Marketplace notice tells you what auto-renewal will do. It does not tell you what other plans cost, what other plans cover, or whether a different plan would fit better.

Letting December 15 pass without a check-in. Even a 15-minute log-in to confirm your income and re-select your plan is materially better than full passive renewal.

Frequently asked questions

What is Marketplace auto-renewal and when does it happen?
Auto-renewal is what the Marketplace does for you if you take no action during Open Enrollment. If you are already enrolled in a 2026 plan and December 15, 2026 passes without you logging in, comparing options, or actively re-selecting a plan, the Marketplace will automatically renew your enrollment for January 1, 2027. The Marketplace will roll you into the same plan if your insurer still offers it, or into a similar plan from a similar carrier if your plan was discontinued. Your reported income, your household size, and your enrollment data carry forward. The auto-renewal is processed before January 1 and your new ID cards arrive in late December or early January. Convenient, yes. Cheap and well-fitted to your 2027 situation, rarely.
Why is auto-renewal especially risky for 2027 coverage?
Four structural forces hit 2027 at the same time. First, the enhanced IRA premium tax credits are fully expired and 2027 is the first plan year fully priced without them. Second, the 400 percent of Federal Poverty Level subsidy cliff is back in full effect, so any household whose 2027 income lands above 400 percent FPL loses APTC entirely on auto-renewal. Third, the DACA APTC rollback effective June 30, 2026 means many DACA recipients no longer qualify for the premium tax credit and need to actively re-evaluate eligibility. Fourth, insurer networks shifted during 2026, with several carriers narrowing provider lists in major metro areas. An auto-renewed plan from 2026 may price differently, subsidize differently, and cover different doctors in 2027 than it did in 2026.
When do I receive notice of my 2027 plan and premium?
Two notices arrive. Your insurance carrier sends a renewal notice in October or early November 2026, showing your 2027 monthly premium, plan changes, formulary changes, and network changes. The Marketplace sends a separate notice in mid-November 2026, confirming whether your plan continues, whether the Marketplace plans to auto-renew you, and what your projected premium tax credit looks like for 2027 based on your last reported income. Both notices arrive before the November 1 start of Open Enrollment, but the Marketplace notice often lags by a week or two. If you have not seen either notice by November 20, log in to HealthCare.gov or your state Marketplace and your carrier portal to pull them down directly.
What is the 400 percent FPL cliff and why does it matter for auto-renewal?
The 400 percent of Federal Poverty Level subsidy cliff was the original ACA rule before the Inflation Reduction Act softened it. Under the original rule, anyone above 400 percent FPL pays the full unsubsidized premium with no Advance Premium Tax Credit. The IRA replaced that cliff from 2021 through 2025 with a smooth 8.5 percent cap on what any household pays for the benchmark Silver plan. The IRA expired December 31, 2025, and 2027 is the first year fully governed by the original 400 percent FPL cliff again. For 2027 coverage, a family of four projecting more than roughly 124,800 dollars in 2027 income would lose subsidies entirely under the original rule. An auto-renewed plan keeps the old subsidy assumption baked in until your income gets re-verified, and the surprise tax bill arrives at filing time.
How do network changes affect an auto-renewed plan?
Carriers re-file networks every plan year, and 2026 saw widespread tightening in several large urban markets. If you were auto-renewed and your primary care doctor or specialist quietly left the network, you will not know until you call to schedule an appointment in January or February. The Marketplace does not flag provider exits during auto-renewal. The only reliable check is to look up each provider you use against the 2027 plan directory on the insurance carrier's website, ideally in November or early December. Pharmacy networks and formularies follow the same pattern: a medication that was a tier 2 in 2026 may shift to tier 3 in 2027, doubling your share of the cost without any change to the plan name.
What should I do instead of letting auto-renewal happen?
Re-shop actively, even if you end up choosing the same plan. The exercise takes 30 to 60 minutes if you prepare ahead. Log in to your Marketplace account between November 1 and December 1. Update your 2027 income projection. Pull your list of doctors and prescriptions. Compare your current plan against the other plans in your area. Confirm your doctors and pharmacy are in network. Confirm your prescriptions are still on the formulary at the same tier. If the math checks out, re-select the same plan as your active 2027 choice. If a different plan fits better, switch. The Marketplace logs your active choice and your subsidy gets recalculated against the 2027 benchmark with your current income, not your 2026 income.
If I miss December 15, can I still re-shop after auto-renewal kicks in?
Yes. December 15 is the deadline to lock in January 1 coverage, but Open Enrollment continues through January 15 federally and January 31 in most state Marketplaces. If you let auto-renewal go through on December 15, you can still log in any time before January 15 (or January 31 on a state Marketplace) and change your plan. The new plan you pick will take effect on February 1 if you enroll between December 16 and January 15, or on March 1 if you enroll between January 16 and January 31 on a state Marketplace. The cost of waiting is one or two months of being on the wrong plan, paying the wrong premium, or having the wrong doctors in network during January and February.
