How Retirees Under 65 Can Find Affordable Health Insurance Before Medicare

Fact-checked by the Smart Insurance 101 editorial team

Finding affordable health insurance before Medicare is one of the biggest financial challenges early retirees face in 2025. If you retire before age 65, you could be uninsured for anywhere from a few months to several years — a gap that can be financially devastating without a solid plan. According to KFF’s 2024 Health Insurance Coverage report, roughly 10% of adults ages 50–64 remain uninsured, often because they’ve left employer-sponsored coverage and haven’t yet identified a replacement.

This coverage gap matters more than ever right now. The Inflation Reduction Act’s enhanced ACA subsidies — which dramatically lowered premiums for Marketplace plans — were extended through 2025, making this one of the most affordable windows in recent history to buy individual coverage. At the same time, healthcare costs continue to climb, and medical coverage is shrinking as costs explode nationwide, making the stakes even higher for those without employer benefits.

This guide is written for adults between ages 55 and 64 who are retiring early, have been laid off, or are planning their exit from the workforce. By following these steps, you’ll be able to compare your real options, estimate what you’ll actually pay, and enroll in coverage that protects your savings until Medicare begins.

Step 1: What Are My Health Insurance Options Before Medicare?

Retirees under 65 have five primary pathways for health coverage before Medicare: the ACA Marketplace, COBRA continuation, Medicaid, a spouse’s employer plan, or a retiree health benefit from a former employer or union. The right choice depends on your income, health needs, and how long you have before turning 65.

How to Do This

Start by listing every option available to you personally before comparing costs. Here is a breakdown of each pathway:

• ACA Marketplace Plans: Individual and family plans sold at HealthCare.gov (or your state exchange). Premium Tax Credits based on income can significantly reduce costs. Open Enrollment runs November 1 through January 15 each year, but job loss triggers a Special Enrollment Period.
• COBRA: Allows you to continue your former employer’s exact plan for up to 18 months. You pay the full premium — both your share and the employer’s share — plus a 2% administrative fee.
• Medicaid: Free or very low-cost government coverage for those with incomes below 138% of the federal poverty level in states that expanded Medicaid. Check eligibility at your state’s Medicaid agency.
• Spouse’s Employer Plan: If your spouse still works and has employer-sponsored insurance, you may be able to join their plan as a qualifying life event. This is often the most cost-effective option.
• Retiree Health Benefits: Some large employers, union plans, and government pensions offer retiree health coverage. Ask your former HR department or union representative if you qualify.

What to Watch Out For

Do not assume COBRA is your only option just because your employer mentions it first at separation. Employers are required to notify you about COBRA, but they are not required to explain Marketplace alternatives. Many retirees pay significantly more than necessary simply because they default to COBRA without comparing.

Step 2: How Do I Know If I Qualify for ACA Subsidies as a Retiree?

Your eligibility for ACA Premium Tax Credits as a retiree is based entirely on your projected Modified Adjusted Gross Income (MAGI) for the year — not your former salary or savings balance. This distinction is critical: even retirees with significant savings in a 401(k) or brokerage account may qualify for large subsidies if their taxable withdrawals are low.

How to Do This

Estimate your MAGI by adding up all taxable income sources you expect for the year. Common income sources for retirees include:

• Traditional IRA or 401(k) withdrawals (taxable portion)
• Social Security benefits (if you’ve begun collecting — up to 85% may be taxable)
• Pension payments
• Capital gains from investment sales
• Part-time or consulting income
• Rental income

Roth IRA withdrawals and most Social Security benefits below certain thresholds do not count toward MAGI. For 2025, the subsidy cliff sits at 400% of the federal poverty level — but Enhanced subsidies under current law cap your premium contribution as a percentage of income at every income level, so there is no hard cutoff that eliminates all help. Use the KFF Health Insurance Marketplace Calculator to model different income scenarios and see your estimated monthly premium.

What to Watch Out For

Be careful about large one-time withdrawals in any year you’re receiving subsidies. Pulling $50,000 from a traditional IRA to fund home repairs, for example, could push you into a higher income bracket and eliminate thousands of dollars in tax credits — creating a repayment obligation at tax time.

Step 3: Should I Choose COBRA or an ACA Marketplace Plan After Retiring Early?

For most early retirees, an ACA Marketplace plan with subsidies will cost significantly less than COBRA — often hundreds of dollars less per month. However, COBRA may be worth it in specific situations, such as when you are in the middle of expensive treatment with providers who are not on any Marketplace network.

How to Do This

Compare the two options side-by-side using actual numbers. Your COBRA election notice (which must arrive within 44 days of your qualifying event) will show the full monthly premium. Then use the KFF Calculator or HealthCare.gov to see your estimated Marketplace premium after subsidies.

When evaluating ACA Marketplace plans, understand the differences between HMO and PPO health insurance structures, since network restrictions vary significantly by plan type. Also review your deductible versus out-of-pocket maximum carefully — a low premium can come with a high deductible that erases any savings if you have significant healthcare needs.

What to Watch Out For

COBRA has a strict 60-day election window from the date you receive your notice. Missing this deadline means losing access to the plan permanently. However, you can elect COBRA retroactively within that 60-day window — meaning you can wait and see if you get sick before deciding to pay the premium.

Step 4: How Do I Actually Enroll in Health Insurance Before Medicare?

To enroll in health insurance before Medicare, you’ll use one of three pathways depending on which coverage type you choose: HealthCare.gov or your state exchange for ACA plans, your former employer’s COBRA administrator for continuation coverage, or your state Medicaid agency for low-income coverage. Each has its own deadline and application process.

How to Do This

Follow these steps based on your situation:

1. Losing job-based coverage (ACA route): You have 60 days from the date you lose coverage to enroll in a Marketplace plan under a Special Enrollment Period. Go to HealthCare.gov’s plan finder, create an account, and answer questions about your household size and expected income. The system will show plans you qualify for, your estimated subsidy, and your net monthly premium.
2. COBRA route: Your former employer or their COBRA administrator (often a company like WEX or Conduent) will send you an election notice. Complete and return the election form within 60 days, along with your first premium payment.
3. Medicaid route: Apply through your state’s Medicaid agency or through HealthCare.gov — both systems will route you correctly. Medicaid applications are accepted year-round with no enrollment window.
4. Spouse’s plan route: Your spouse’s employer HR department handles this. Your retirement is a qualifying life event that allows your spouse to add you to their plan mid-year. Notify them within 30 days of your coverage end date.

What to Watch Out For

When applying through HealthCare.gov, the income you enter is your estimate for the full calendar year. If your actual income ends up higher, you may owe back some subsidies at tax time. If it ends up lower, you may receive a refund. Update your income estimate on the Marketplace anytime it changes to avoid large year-end surprises.

Step 5: How Can I Keep Health Insurance Costs Low Until I Turn 65?

The most effective way to keep health insurance before Medicare affordable is to actively manage your taxable income each year to maximize subsidy eligibility, and to choose the right plan metal tier for your actual healthcare usage. Passive choices — like automatically renewing a plan or ignoring income changes — routinely cost retirees hundreds of dollars per month unnecessarily.

How to Do This

Use these strategies to reduce your out-of-pocket costs year after year:

• Choose Silver for cost-sharing reductions (CSR): If your income is between 100% and 250% of the federal poverty level, Silver-tier plans come with Cost-Sharing Reductions that lower your deductible, copays, and out-of-pocket maximum — but only on Silver plans. This is the single most valuable subsidy available and is often overlooked.
• Use a Health Savings Account (HSA): If you enroll in a High-Deductible Health Plan (HDHP), you can contribute pre-tax dollars to an HSA. In 2025, the HSA contribution limit is $4,300 for individuals and $8,550 for families, per IRS Publication 969. Note: once you enroll in Medicare, HSA contributions must stop — so maximize contributions before that transition.
• Shop the Marketplace every year: Insurer pricing changes annually. The plan that was cheapest last year may not be cheapest this year. Log in and compare during Open Enrollment each November.
• Manage capital gains carefully: Realizing large capital gains from investment sales can push your MAGI above subsidy-friendly thresholds. Spread gains across multiple years when possible.
• Look into PACE or retiree dental coverage separately: Dental is not typically included in ACA plans. Our dedicated guide on understanding dental insurance benefits and costs explains your options for adding coverage affordably.

What to Watch Out For

Do not stop at health insurance when budgeting retirement risk. Many early retirees also need to revisit life insurance coverage as their employer group policy lapses. Our review of the best term life insurance companies can help you find replacement coverage if needed.

Frequently Asked Questions

How much does health insurance cost per month before Medicare if I retire at 62?

The average benchmark Silver plan for a 62-year-old costs approximately $1,050/month before subsidies, but most early retirees qualify for Premium Tax Credits that reduce this substantially — sometimes to under $200/month. Your actual cost depends on your projected income: use the KFF Subsidy Calculator with your specific income to get a personalized estimate.

Can I get free health insurance before Medicare if I retire early with low income?

Yes — retirees with incomes below 138% of the federal poverty level (about $20,120/year for a single person in 2025) qualify for Medicaid in the 40 states that have expanded Medicaid, which provides comprehensive coverage at no cost or very low cost. Even retirees above that threshold may qualify for $0-premium Silver plans if their income falls below 150% FPL, per HealthCare.gov’s cost assistance guidelines.

What happens to my health insurance if I retire before 65 and my spouse is still working?

You can join your spouse’s employer health plan as a dependent — your retirement counts as a qualifying life event that allows mid-year enrollment, and your spouse has 30 days from your coverage end date to add you. This is often the most cost-effective option, as employers subsidize a meaningful portion of the premium even for dependents. Contact your spouse’s HR department immediately after your last day of work.

Is COBRA worth it for a 60-year-old early retiree?

COBRA is rarely the most cost-effective choice for early retirees unless you are mid-treatment and need to keep your exact doctors and coverage in place. The average COBRA premium for individual coverage is $624/month, compared to potentially $0–$300/month on a subsidized ACA plan. The one scenario where COBRA makes sense is if you anticipate major surgery or ongoing treatment and your providers are not in any available Marketplace network.

Can I contribute to an HSA while I’m on an ACA plan before Medicare?

Yes — if you enroll in a High-Deductible Health Plan (HDHP) through the ACA Marketplace, you can contribute to a Health Savings Account. For 2025, the limit is $4,300 for self-only coverage and $8,550 for family coverage, per IRS guidelines. However, you must stop contributing to your HSA in the month you enroll in Medicare Part A or Part B — so time this transition carefully.

What is the penalty for going without health insurance before Medicare at age 63?

There is no federal penalty for being uninsured since the ACA’s individual mandate penalty was eliminated in 2019. However, some states — including California, Massachusetts, New Jersey, Rhode Island, and Vermont — have their own individual mandate with state-level penalties for being uninsured. Beyond penalties, going without coverage is a significant financial risk: a single hospitalization can cost $30,000 or more without insurance.

How do I avoid an ACA subsidy repayment at tax time as a retiree?

Report income changes to the Marketplace as soon as they happen throughout the year. If your actual income is higher than estimated, you’ll owe back some of your Premium Tax Credits when you file taxes. The safest approach is to update your income estimate on HealthCare.gov every time you take a significant IRA withdrawal or realize a capital gain. The IRS Form 8962 reconciles your advance payments with your actual income each year.

Can a self-employed retiree doing consulting work get subsidized ACA coverage?

Yes — consulting or freelance income counts as self-employment income and does not disqualify you from ACA subsidies. What matters is your total MAGI relative to the federal poverty level. In fact, self-employed individuals can deduct their health insurance premiums, which further reduces their MAGI. For a deeper look at coverage options for those with self-employment income, see our guide on health insurance for self-employed workers in 2026.

Does early retirement affect when I can start Medicare?

No — Medicare eligibility is based solely on age, not employment status. You become eligible for Medicare at 65 years old regardless of when you retire. If you worked and paid Medicare taxes for at least 10 years (40 quarters), you qualify for premium-free Medicare Part A. Your retirement date has no impact on this timeline.

What if I have a pre-existing condition — can I still get health insurance before Medicare?

Yes — ACA Marketplace plans are legally required to accept all applicants regardless of medical history and cannot charge higher premiums for pre-existing conditions. This protection, established by the Affordable Care Act, applies to all plans sold through the Marketplace. You cannot be denied coverage or charged more because of conditions like diabetes, heart disease, or cancer, per HHS’s ACA pre-existing condition protections.
