Retiring between ages 55 and 64 creates a coverage gap that can last a decade. You lose employer-sponsored health insurance the day you stop working, but Medicare does not start until you turn 65. For ages 60-64, the core pre-retiree window, the ACA marketplace is the dominant solution. Premium tax credits (PTCs) are available to early-retirees with household income between 100% and 400% of the federal poverty level. Because retirement income (pensions, 401(k) distributions, capital gains) can be managed to stay below the 400% FPL ceiling, many near-retirees and ages 60-64 retirees qualify for substantial subsidies.
This guide covers all four options available to pre-65 retirees, the income thresholds that determine subsidy eligibility, HSA timing rules (contributions stop when Medicare Part A starts), and the Medicare transition at 65 including IRMAA surcharges that can significantly raise Part B costs for higher-income retirees. Understanding these factors before you retire, not after, is when planning pays off. When you approach 65, read the turning 65 Medicare guide alongside this page, and compare Medigap vs Medicare Advantage before your Initial Enrollment Period opens.
Your 5 Real Options
Available options| Option | Best for | Typical cost |
|---|
| ACA Marketplace with PTC | Most pre-65 retirees under 400% FPL | $50 to $600/month after subsidies |
| COBRA continuation | Bridge only, use when Medicare is under 18 months away | $600 to $1,800/month (102% of full premium) |
| Spouse's employer plan | Married, spouse still working with employer coverage | Varies, often cheaper than COBRA or marketplace |
| Employer retiree health benefits | Retirees whose former employer offers retiree coverage | Varies; often subsidized until Medicare at 65 |
| Medicare at 65 | All retirees who turn 65 (automatic transition target) | $202.90/month Part B standard; IRMAA adds more if income is high |
ACA subsidy eligibility ends at 400% FPL ($63,840 for a single person in 2026). Above that, full unsubsidized marketplace rates apply. COBRA costs represent 102% of the total employer-plus-employee premium.

Option 1: ACA Marketplace with Premium Tax Credits
For pre-65 retirees (whether ages 60-64, early-retirees who left at 55, or near-retirees bridging to Medicare) the ACA marketplace is the primary solution. Premium tax credits (PTCs) are available for household income between 100% and 400% of the federal poverty level. At 400% FPL for a single person in 2026 that ceiling is $63,840. The subsidy cliff returned in 2026: household income a dollar above 400% FPL means zero PTC, no matter how expensive the plan.
Retirement income is not always fixed. Many pre-retirees in the transitioning-to-Medicare window can manage their Modified Adjusted Gross Income (MAGI) through careful timing of 401(k) withdrawals, Roth conversions, and capital gain realizations. A pre-65 retiree drawing $55,000 annually in retirement income may qualify for hundreds of dollars per month in PTC on a Silver plan. If income needs to stay below 400% FPL, a financial planner familiar with ACA income planning is worth consulting before each enrollment year.
Option 2: COBRA Continuation Coverage
COBRA lets you keep your former employer's exact plan for up to 18 months after leaving a job. The cost is 102% of the full premium, covering both your share and the employer's share, plus a 2% administrative fee. For a single person, that typically runs $600 to $1,200 per month. For a family, it can exceed $2,500 to $3,300 per month. This is rarely the best financial choice for a pre-65 retiree with years to wait before Medicare.
COBRA is useful in two situations: (1) you are a soon-to-be-Medicare-eligible retiree and Medicare starts within 18 months, making COBRA a cleaner bridge than shopping marketplace plans mid-year; or (2) you have ongoing care with a specific provider network that the marketplace plans in your area do not cover. Outside those scenarios, compare COBRA against ACA marketplace plans with PTC. A pre-65 retiree household under 400% FPL will almost always find a subsidized marketplace plan cheaper than COBRA.
Option 3: Spouse's Employer Plan
If your spouse is still working and has employer health benefits, joining their plan is typically the cheapest pre-65 option. Employer-sponsored premiums are paid pre-tax through payroll, which reduces the effective cost by roughly 20% to 30% compared to post-tax marketplace premiums. This option has no income limits and does not expire. It lasts as long as your spouse remains employed with that employer.
One planning note: if you are a pre-65 retiree on your spouse's employer plan and your spouse also retires before 65, losing that coverage is a qualifying life event that opens a 60-day ACA Special Enrollment Period (SEP). You can use that SEP to enter the marketplace mid-year. Do not miss the 60-day window.
Option 4: Employer Retiree Health Benefits
Some large employers (particularly government agencies, unions, and Fortune 500 companies) offer retiree health coverage to workers who leave at a qualifying age and service combination (often age 55 with 10+ years of service). This coverage varies widely. Some plans mirror active-employee coverage and subsidize most of the premium; others provide a fixed dollar contribution toward marketplace plans. Most employer retiree plans are designed to wrap with Medicare at 65, at which point they convert to a Medicare supplement or retiree drug plan.
If your former employer offers retiree coverage, get the full plan details in writing before enrolling. Key questions: Does coverage continue past 65 or terminate when you become Medicare-eligible? What is the premium, and does it change annually? Is the network the same as the active-employee plan? Does it coordinate with Medicare as primary or secondary payer? Retiree coverage is increasingly rare at small and mid-sized employers, so do not assume you have it without verifying.
Option 5: Medicare at 65 (Your End Goal)
Every pre-65 retiree becomes Medicare-eligible at 65. The standard 2026 Part B premium is $202.90 per month. Part A (hospital) is premium-free for most people who worked 40+ quarters. The Initial Enrollment Period opens three months before your 65th birthday and runs through three months after. Missing this window without creditable coverage causes permanent late-enrollment penalties on Part B (10% per 12-month period delayed).
Higher-income retirees face IRMAA (Income-Related Monthly Adjustment Amount) surcharges on top of the standard Part B premium. IRMAA is based on your MAGI from two years prior, so your 2026 Medicare premium is set by your 2024 income. Single filers with 2024 MAGI above $109,000 and joint filers above $218,000 pay more than the standard rate. Part B premiums with IRMAA range from $284.10 to $689.90 per month depending on income tier. Part D drug plans carry separate IRMAA surcharges from $14.50 to $91.00 per month. See the bridging section below for full IRMAA detail.
Traps That Cost Early Retirees Thousands
Pre-65 retirees face several coverage traps, especially when leaving employer coverage for the first time without a clear plan:
Common traps for Early Retirees| Trap | Why to avoid |
|---|
| Assuming COBRA is your only option | COBRA costs 102% of the full premium, often $800 to $1,800/month for a single person. ACA marketplace plans with PTCs are usually far cheaper for early-retirees under 400% FPL. |
| Buying a catastrophic plan after 30 | Catastrophic plans are only available to people under 30 or those with a hardship exemption. Ages 60-64 retirees are categorically ineligible. Enrolling in the wrong plan type leads to claims being denied. |
| Triggering the 400% FPL subsidy cliff with a large Roth conversion | A Roth conversion that pushes MAGI above 400% FPL eliminates ALL PTC for that year, not just the portion attributable to the extra income. On a $1,200/month Silver plan, that can mean $14,400 in unexpected premium costs. Model conversions against the ACA cliff before executing. |
| Contributing to an HSA after Part A Medicare enrollment | Once you enroll in Medicare Part A (even retroactively through Social Security), HSA contributions stop being allowed. Contributions made after enrollment are subject to a 6% annual excise tax. Stop contributions the month before Medicare begins. |
| Missing the IRMAA two-year lookback on retirement income | IRMAA is based on income from two years ago. A near-retiree who earned $180,000 at age 63 will pay IRMAA surcharges at 65 and 66 even if retirement income is now $55,000. Plan for higher Part B costs in the first two Medicare years if prior income was above $109,000 (single) or $218,000 (joint). |
| Short-term health plans as a long-term pre-65 strategy | Short-term plans do not cover pre-existing conditions, can deny claims, and are not ACA-compliant. A pre-retiree using a short-term plan for 3 to 5 years before Medicare faces enormous financial exposure. Stick with ACA marketplace plans. |
The catastrophic plan ineligibility rule is absolute: individuals over 30 who do not have a qualifying hardship exemption cannot enroll in a catastrophic marketplace plan regardless of income.

Bridging from Early Retirement to Medicare at 65
For a soon-to-be-Medicare-eligible retiree, the bridge period is the gap between your last day of employer coverage and the first day of Medicare. If you retire at 62 and Medicare begins at 65, that gap is roughly 36 months, too long for COBRA (18 months max) and long enough to make marketplace coverage the anchor solution.
IRMAA (Income-Related Monthly Adjustment Amount) is the surcharge that higher-income retirees pay on top of the standard Medicare Part B premium. In 2026, the standard Part B premium is $202.90 per month. IRMAA kicks in when 2024 MAGI exceeds $109,000 for single filers or $218,000 for joint filers. At the first tier, Part B premiums jump to $284.10 per month. The top IRMAA tier (single MAGI above $500,000 or joint above $750,000) brings Part B to $689.90 per month. Part D prescription drug plans carry separate IRMAA surcharges ranging from $14.50 to $91.00 per month.
The two-year lookback is the key planning variable. IRMAA for 2026 is set by 2024 income, not current retirement income. A transitioning-to-Medicare retiree who earned a high salary in their final working year should budget for IRMAA surcharges in their first two years of Medicare even if retirement income is now modest. If your income genuinely drops (retirement, job loss, divorce, death of spouse), you can appeal the IRMAA determination using SSA Form SSA-44 to request recalculation based on a more recent year's income.
When you turn 65, your ACA marketplace plan automatically ends and Medicare begins. Do not drop marketplace coverage early; it runs until the Medicare effective date. If you have an employer retiree plan, coordinate the handoff: most retiree plans require you to enroll in Medicare Parts A and B before retiree coverage transitions to a wrap plan or drug plan. Missing enrollment triggers can result in coverage gaps or permanent premium penalties.
Premium Tax Credit Strategy for Pre-65 Retirees
The premium tax credit (PTC) is the most powerful financial tool available to pre-65 retirees, and managing income to stay within the PTC window is the central financial planning task of the pre-Medicare years. In 2026, household income between 100% and 400% FPL qualifies for PTC. For a single person, the 2026 FPL is $15,960, making the subsidy range $15,960 to $63,840. For a two-person household, the range is $21,640 to $86,560. See Medicare Savings Programs by state for additional low-income assistance that bridges into Medicare.
Income sources that count toward MAGI for PTC purposes include: traditional IRA and 401(k) distributions, pension income, Social Security benefits (85% of benefits count for higher earners), interest, dividends, capital gains, and rental income. Roth IRA distributions, HSA distributions used for qualified medical expenses, and return of basis from annuities do NOT count toward MAGI. This matters enormously for income management.
The 400% FPL subsidy cliff is severe in 2026. A pre-65 retiree household that earns $63,841, a dollar above the single-person ceiling, receives zero PTC. On an unsubsidized Silver plan running $1,200 to $1,500 per month for someone in their early 60s, that is a difference of $10,000 to $18,000 per year in out-of-pocket premium costs. Staying below the ceiling through careful retirement income sequencing is often worth more than the underlying investment returns.
Silver plans with cost-sharing reductions (CSRs) are available to early-retirees with household income between 100% and 250% FPL. CSRs reduce deductibles, copays, and out-of-pocket maximums on Silver plans only; they do not apply to Gold or Bronze. A pre-retiree household managing income to the 200% FPL range ($31,920 single) may find a Silver plan with CSRs provides Gold-level coverage at Bronze-level premiums.
HSA Rules for Pre-65 Retirees: Use It Before You Lose the Contribution Window
Health Savings Accounts (HSAs) are among the most tax-efficient tools available to a pre-65 retiree. If you enroll in an HSA-eligible High-Deductible Health Plan (HDHP) on the ACA marketplace, you can contribute up to $4,400 (self-only) or $8,750 (family) in 2026, plus a $1,000 catch-up for those 55 and older. HSA contributions are tax-deductible (or pre-tax if through payroll), grow tax-free, and are withdrawable tax-free for qualified medical expenses.
The critical rule: HSA contributions stop the month you enroll in Medicare Part A. If you sign up for Social Security at 65, you are automatically enrolled in Medicare Part A. If Medicare Part A enrollment is retroactive (Social Security can retroactively back-date coverage up to 6 months), your last valid HSA contribution month moves back accordingly. A near-retiree planning to delay Social Security past 65 can keep an HSA-eligible HDHP and continue contributing, but must stop contributing at least 6 months before Medicare begins if accepting retroactive coverage.
Accumulated HSA balances can still be used after Medicare enrollment; they are just no longer contribution-eligible. HSA funds can pay Medicare Part B premiums, Part D premiums, Medicare Advantage premiums, dental, vision, and any qualified out-of-pocket medical costs, all tax-free. A pre-65 retiree who maximizes HSA contributions for several years before 65 builds a powerful tax-free medical reserve for the Medicare years.
Frequently Asked Questions
What health insurance do early retirees get before Medicare?
Pre-65 retirees have four main options: (1) ACA marketplace plans with premium tax credits, the most common path for ages 60-64, (2) COBRA continuation from a former employer for up to 18 months, (3) a spouse's employer plan if a spouse is still working, and (4) employer retiree health benefits if offered. The ACA marketplace with subsidies is the best financial choice for most early-retirees whose household income is below 400% FPL ($63,840 single in 2026).
Can early retirees get ACA subsidies?
Yes. Pre-65 retirees with household income between 100% and 400% FPL qualify for Premium Tax Credits on the ACA marketplace. In 2026, the subsidy cliff returned; income one dollar above 400% FPL eliminates all PTC. Retirement income (401(k) withdrawals, pensions, capital gains) counts toward MAGI, so income management matters. A near-retiree keeping MAGI below $63,840 single can qualify for hundreds of dollars per month in subsidies on a Silver plan.
How much does COBRA cost for early retirees?
COBRA costs 102% of the full premium, covering both the employee share and the employer share, plus a 2% admin fee. For an individual, that typically runs $600 to $1,200 per month in 2026. For a family, costs often exceed $2,500 per month. COBRA lasts a maximum of 18 months. For a transitioning-to-Medicare retiree within 18 months of turning 65, COBRA may be a cleaner bridge. For ages 60-64 retirees with more time before Medicare, marketplace plans with PTCs are usually far cheaper.
What is IRMAA and how does it affect early retirees?
IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to Medicare Part B and Part D premiums for higher-income beneficiaries. In 2026, IRMAA applies when 2024 MAGI exceeds $109,000 for single filers or $218,000 for joint filers. The standard Part B premium is $202.90 per month. With IRMAA, it can rise to $284.10 to $689.90 depending on income tier. Key trap: IRMAA is based on income from two years ago, so a soon-to-be-Medicare-eligible retiree with high prior-year income should budget for IRMAA in early Medicare years.
Can early retirees use an HSA before Medicare?
Yes, as long as they are enrolled in an HSA-eligible HDHP and not yet on Medicare. Pre-65 retirees aged 55+ can contribute up to $4,400 (self) or $8,750 (family) plus a $1,000 catch-up contribution in 2026. Contributions must stop the month Medicare Part A begins. If Medicare enrollment is retroactive through Social Security, stop contributions at least 6 months before Medicare start. Existing HSA balances can still be spent tax-free on qualified medical and Medicare expenses after enrollment.
Can early retirees buy a catastrophic health plan?
No, not at ages 60-64. Catastrophic marketplace plans are available only to individuals under 30 or those with a specific qualifying hardship exemption. Pre-retirees and ages 60-64 retirees are categorically ineligible regardless of income. Attempting to enroll will result in rejection, and claims under such a plan would be denied. Early-retirees should compare Bronze, Silver, and Gold ACA plans based on their expected healthcare use.
What happens to ACA marketplace coverage when an early retiree turns 65?
Medicare becomes primary coverage at 65 and the ACA marketplace plan ends. Do not cancel marketplace coverage before Medicare begins; let it run through the end of the last coverage month. Medicare Part B enrollment should be completed during your Initial Enrollment Period (3 months before to 3 months after your 65th birthday). If you have employer retiree benefits, coordinate the handoff: most retiree plans require Medicare Parts A and B as a condition of continued retiree coverage post-65.
What income counts toward ACA subsidy calculations for early retirees?
MAGI for ACA PTC purposes includes: traditional IRA and 401(k) distributions, pension income, Social Security benefits (up to 85% for higher earners), interest, dividends, capital gains, and rental income. It does NOT include Roth IRA distributions, HSA distributions used for qualified medical expenses, or return of basis from annuities. Managing which accounts you draw from during pre-65 retirement directly affects your PTC subsidy amount and can save thousands per year.
