ACA Open Enrollment 2027: A Shopping Checklist for Early Retirees

Picture a hypothetical early retiree, age 61, who retired in the spring. Last year a plan was picked quickly and it worked fine. This fall, a renewal notice arrives and the easy move is to do nothing and let it roll over. That quiet default is exactly what this checklist is meant to challenge.

The marketplace for 2027 looks different from a few years ago. This article is general education, not personal advice. It walks through the questions many early retirees weigh while shopping, so you can approach the process with a clearer map.

Four facts frame this year's shopping season.

• Dates. Open enrollment for 2027 coverage began November 1, 2026. In states using HealthCare.gov, enrolling by December 15 is generally needed for coverage to start January 1, and the window closes January 15, 2027. State-run marketplaces may use different dates, so it is worth checking your own state's exchange. You can confirm details at HealthCare.gov.
• Premiums. KFF reports that finalized benchmark silver premiums are up an average of 13% for 2027, following a 26% increase for 2026. Averages hide wide variation by state, county, and insurer.
• Subsidies. The enhanced premium tax credits expired at the end of 2025. As a result, households above 400% of the federal poverty level receive no premium tax credit. This threshold is often called the subsidy cliff, and early retirees who control their own income can find themselves on either side of it. Our post on the ACA subsidy cliff and income before open enrollment explores the mechanics.
• Insurer exits. KFF reports several insurers are leaving states, including Cigna exiting the individual market in all 11 states where it sold plans.

None of this predicts what lawmakers may or may not do later. It simply describes the rules in place for this enrollment period.

Think of this like comparing cars. The sticker price matters, but fuel, repairs, and insurance shape the real cost. Health plans work the same way. Here are the items many shoppers work through.

1. Do not let auto re-enrollment decide for you. If you take no action, many marketplaces renew your current plan, or a similar one, automatically. That plan's premium, network, and drug coverage may have changed, and if your insurer is exiting, the plan may not exist. Reviewing your renewal notice and then browsing the full set of options is a common way to avoid surprises.

2. Compare the total picture, not premium alone. Three numbers work together:

• Net premium: what you pay each month after any premium tax credit.
• Deductible: what you pay for covered services before the plan starts sharing costs (some services are covered earlier).
• Out-of-pocket maximum: the most you would pay in a year for covered in-network care. This is your worst-case ceiling, excluding premiums.

A lower premium often comes with a higher deductible and ceiling. Some people add up twelve months of premiums plus the out-of-pocket maximum to see a plan's worst-case annual cost, then weigh that against their health needs and cash reserves.

3. Check that your doctors and prescriptions are still covered. Networks and drug lists can change from year to year, and plans can differ even within one insurer. Many shoppers search for each doctor, specialist, and hospital by name in the plan's provider directory, and then confirm with the office directly. For medications, the plan's formulary shows whether a drug is covered and at what tier. If an insurer in your area is exiting, a move to a new carrier could mean a new network entirely.

4. Estimate 2027 income carefully. Premium tax credits are based on your expected modified adjusted gross income (MAGI) for the coverage year, not last year's. Early retirees may have income from several sources: part-time work, taxable account withdrawals, capital gains, interest, IRA withdrawals, or Roth conversions. Because the 400% line now acts as a hard edge, even a modest estimating error can change the credit significantly. If income ends up higher than estimated, the IRS may require repayment of excess credit when you file taxes, a process reported on Form 8962. Updating your marketplace application if income changes during the year is another common step.

5. Understand the plan metal tiers. Bronze, silver, gold, and platinum describe how costs are split on average, not quality of care. Bronze plans typically have lower premiums and higher deductibles. Silver plans can offer cost-sharing reductions for households with lower incomes, an option that may not be available on other tiers. Gold and platinum generally have higher premiums with lower out-of-pocket costs.

6. Look at other coverage routes. Depending on circumstances, some people compare marketplace plans with COBRA, a spouse's employer plan, or retiree coverage. Our guide to COBRA versus the marketplace lays out the trade-offs, and if you recently left a job, this playbook for the first 90 days after a layoff covers related timing questions.

"My plan will just renew, so I'm covered." It may renew, but possibly at a different price, with different benefits, or not at all if the insurer is leaving your state.

"The cheapest premium is the cheapest plan." A low premium paired with a high deductible can cost more in a year with significant medical needs.

"Being retired means I can't qualify for assistance." Eligibility for a premium tax credit generally depends on income and coverage options, not employment status. With the enhanced credits gone, though, income above 400% of the federal poverty level means no credit.

"I can fix it all later." Outside open enrollment, changing plans generally requires a qualifying life event. Missing the window can leave a household with limited options, so understanding the dates for your state matters.

"Medicare is just around the corner, so it doesn't matter." Even a year or two of coverage can be costly. And when Medicare eligibility approaches, timing matters; our explainer on Medicare Part B and Part D late enrollment penalties covers what to know.

This example is fictional and for illustration only. Consider a hypothetical couple, both 62, who retired this year. Plan A has a lower monthly premium but a high deductible and out-of-pocket maximum. Plan B costs more each month but has a lower ceiling. If one spouse has ongoing prescriptions and specialist visits, Plan B's total yearly cost could end up lower in a high-use year, while Plan A may come out ahead in a low-use year. Neither plan is automatically better. The point is that comparing the full cost range, plus network and drug coverage, reveals trade-offs that the premium alone hides.

Shopping for coverage as an early retiree is less about finding a perfect plan and more about understanding the trade-offs. Many people weigh net premium, deductible, and out-of-pocket maximum together, confirm that doctors and prescriptions are covered, and estimate 2027 income as carefully as they can. Because rules and dates can differ by state, checking your own marketplace's deadlines is an important step.

Healthcare costs interact with the rest of your finances too, from income planning to the move onto Medicare. If you are weighing work options, this look at un-retiring touches on coverage as one factor.
