How to Retire Before 65 Without Losing Sleep Over Health Insurance

Reviewed: October 2026. Marketplace rules and dollar limits can change each year. Verify your eligibility, premiums and plan details through HealthCare.gov or your state Marketplace before enrolling.

Many people are financially ready to leave work before 65 but hesitate for one reason: health insurance.

The years between employer coverage and Medicare can feel like a dangerous gap. A serious illness could be expensive, COBRA may cost far more than expected, and an Affordable Care Act Marketplace plan can look unpredictable because its price depends partly on income.

The good news is that this gap can be planned. For many early retirees, the ACA Marketplace is a workable bridge to Medicare. The difficult part is understanding that the Marketplace measures income, not spending. Where your retirement cash comes from may change the subsidy even when your lifestyle stays exactly the same.

The healthcare gap before 65

Most people become eligible for Medicare at 65. If you retire earlier, you need another source of coverage for every month in between. Common choices include:

• a spouse’s active employer plan;
• retiree medical coverage from a former employer;
• COBRA continuation coverage;
• an ACA Marketplace plan;
• Medicaid, if household income and state rules qualify; or
• another form of individual coverage.

Do not compare premiums alone. Check the deductible, maximum out-of-pocket limit, prescription formulary, provider network and whether care outside your local area is covered. A cheaper plan may be a poor fit if it excludes an important doctor or medication.

RetireNerd’s Health Insurance Before Medicare guide compares COBRA and Marketplace coverage in detail. This article focuses on the income-planning side of the Marketplace.

How the ACA Marketplace subsidy works

The Premium Tax Credit can reduce the monthly cost of a Marketplace plan. The Marketplace estimates the credit using the household information and expected annual income you report. You can apply all, some or none of the estimated credit to your monthly premium. The final amount is reconciled on your federal tax return using Form 8962.

For 2026 coverage, the temporary subsidy expansion that applied from 2021 through 2025 has ended. In general, household income must be between 100% and 400% of the applicable federal poverty level to receive the Premium Tax Credit. The Marketplace uses the prior year’s poverty guidelines for the coverage year.

Within the eligible range, the credit generally becomes smaller as income rises. In 2026, the expected household contribution toward the benchmark plan rises on a sliding scale and reaches 9.96% of income at the upper end. The benchmark is the second-lowest-cost Silver plan available to the household, but the credit may be applied to eligible plans in other metal categories.

At more than 400% of the poverty level, the Premium Tax Credit generally becomes zero. That abrupt cutoff is commonly called the subsidy cliff.

Who can qualify for Marketplace premium assistance?

Income is only one part of eligibility. In general, a person claiming the Premium Tax Credit must:

• enroll in an eligible plan through the federal or state Marketplace;
• have household income within the applicable range;
• be a U.S. citizen, U.S. national or lawfully present immigrant who meets Marketplace requirements;
• live in the United States and not be incarcerated;
• not be claimed as another person’s tax dependent;
• generally file a joint federal return when married, unless a limited exception applies; and
• not be eligible for qualifying government coverage or affordable employer coverage that provides minimum value.

For 2026, employer coverage is generally considered affordable for the employee when the employee’s required contribution for the applicable lowest-cost qualifying option does not exceed 9.96% of household income. Different details can apply to family members and health reimbursement arrangements.

If income is low enough, the application may send a household member to Medicaid instead. In states that expanded Medicaid, many adults qualify at incomes up to about 138% of the federal poverty level. In a state that has not expanded Medicaid, an adult with income below 100% of poverty can fall into a coverage gap unless another eligibility category applies. This is one reason an early retiree should test the actual state application rather than relying on a national estimate.

Marketplace income is MAGI—not the amount you spend

The Marketplace uses household modified adjusted gross income, usually called MAGI. Start with federal adjusted gross income and add back tax-exempt interest, nontaxable Social Security benefits and excluded foreign income. The income of a spouse and tax dependents who are required to file may also count, even if they do not need Marketplace coverage.

This distinction creates a planning opportunity. A household may spend $80,000 during a year while reporting much less than $80,000 of Marketplace MAGI if part of its spending comes from cash already saved, brokerage-account basis or qualified Roth distributions. Another household could spend the same amount but show much higher MAGI because most of the cash came from a traditional IRA.

How a retirement withdrawal can push you over the cliff

Suppose a single 63-year-old retiree expects $58,000 of 2026 MAGI. That is below the $62,600 upper limit for a one-person household in the contiguous states. Late in the year, the retiree converts $12,000 from a traditional IRA to a Roth IRA. Unless another item offsets it, the conversion raises MAGI to approximately $70,000.

The conversion may be sensible as a long-term tax strategy, but it can eliminate the entire Marketplace credit for that year. The true cost is not merely the income tax on the conversion. It can also include the lost subsidy.

The same problem can arise from:

• a large traditional IRA distribution;
• a year-end Roth conversion;
• selling appreciated stock, mutual funds, real estate or cryptocurrency;
• capital-gain distributions from a mutual fund;
• starting Social Security during the year;
• a pension beginning earlier than planned;
• unexpected consulting or self-employment income; or
• a lump-sum payment or debt cancellation.

Starting in 2026, there is another reason to be careful: the federal repayment caps for excess advance Premium Tax Credits have been eliminated. If the Marketplace paid more credit in advance than the tax return ultimately allows, the household may have to repay the full excess amount.

A better strategy: create an ACA income budget

An ACA income budget is a target range for annual household MAGI during the years before Medicare. It should sit beside the normal spending budget.

1. Estimate annual spending. Include premiums, deductibles, prescriptions, taxes, home repairs and irregular expenses.
2. Set a provisional MAGI range. Use household size, state, expected Marketplace prices and the current subsidy rules. Leave a margin below any hard cutoff.
3. List unavoidable income. Include wages, pensions, dividends, interest, rental profit, Social Security and required taxable distributions.
4. Choose flexible cash sources. Identify cash reserves, high-basis taxable assets, qualified Roth money and other sources that may fund spending without the same increase in MAGI.
5. Test tax moves before executing them. Price a Roth conversion or appreciated-asset sale after accounting for federal tax, state tax and the change in the Marketplace credit.
6. Review income quarterly. Update the Marketplace promptly when the estimate materially changes.

The goal is not to force income as low as possible. Very low income may lead to Medicaid, and in a non-expansion state it can create a serious eligibility problem. The goal is to choose a realistic income range that supports the retirement plan and produces an accurate Marketplace application.

Example 1: using several account types to cover spending

Consider a married couple, both age 62, who need $90,000 for spending and taxes. Assume they live in one of the 48 contiguous states, have no dependents and want to remain safely below the 2026 two-person cliff of $84,600.

The household spends $90,000, but estimated MAGI is about $64,000. That may preserve a Premium Tax Credit while leaving room for ordinary income variation. Before using this approach, the couple should verify that the Roth distribution is qualified, confirm taxable-account basis and consider the long-term effect of drawing from each account.

Example 2: separating a Roth conversion from the coverage years

A 61-year-old plans to retire in June. Salary already earned during the first half of the year will make that calendar year’s income high enough to receive little or no subsidy. Instead of forcing income down after retirement, the retiree uses COBRA through December and completes a planned Roth conversion in the same high-income year.

The following January, the retiree enrolls in a Marketplace plan during Open Enrollment. With wages gone, the new year’s MAGI can be managed using modest traditional IRA withdrawals, taxable-account basis, cash and qualified Roth distributions. This strategy concentrates income in the year when the Marketplace credit was already limited and protects the following full coverage year.

This does not automatically make COBRA the better choice. The retiree must compare the actual COBRA premium, network and deductible with a midyear Marketplace plan. The example shows why calendar-year timing matters.

Ways to manage MAGI without weakening the retirement plan

• Build cash before leaving work. Money already in checking or savings can fund spending without the withdrawal of principal becoming income. Interest still counts.
• Know the basis in taxable investments. When an investment is sold, the capital gain generally affects MAGI—not the entire sale proceeds.
• Use qualified Roth money carefully. Qualified Roth distributions generally do not increase Marketplace MAGI, but spending Roth assets today may reduce future tax flexibility.
• Coordinate Roth conversions. Complete larger conversions before the Marketplace years, after Medicare begins or only to the extent that the combined tax-and-subsidy cost remains worthwhile.
• Control realized gains. Choose tax lots, harvest losses where appropriate and avoid accidental large gains near year-end.
• Consider deductible contributions when eligible. A deductible traditional IRA contribution or HSA contribution may reduce AGI, but eligibility rules apply and the money must fit the broader plan.
• Keep a buffer. Interest, dividends and year-end fund distributions are not always perfectly predictable. A target exactly one dollar below the cliff is fragile.
• Use less than the full advance credit if income is uncertain. Paying a little more each month may reduce the chance of a large tax bill when the credit is reconciled.

Do not let the subsidy tail wag the retirement dog

Saving several thousand dollars on health insurance can be valuable. It is still only one part of the retirement plan.

A retiree should not skip needed care, hold an unsuitable investment, take on expensive debt or empty a Roth account solely to preserve a subsidy. Nor should someone avoid every Roth conversion if paying a little more for health insurance now could reduce much larger taxes later.

The right comparison is the total household result:

• insurance premiums and out-of-pocket exposure;
• federal and state income taxes;
• future required distributions;
• the remaining mix of taxable, tax-deferred and Roth assets;
• investment risk and liquidity; and
• the quality of the available health plans.

Enrollment timing matters

Losing qualifying job-based health coverage generally creates a Marketplace Special Enrollment Period. The window usually begins 60 days before the coverage loss and continues for 60 days afterward. Annual Open Enrollment also provides an opportunity to enroll for the next plan year.

Voluntarily dropping COBRA before it is exhausted generally does not create a new Special Enrollment Period. Losing COBRA because the maximum coverage period ends usually does. Confirm the effective dates before leaving work so the old and new plans do not leave an unintended gap.

A pre-retirement healthcare checklist

• Ask HR for the exact last day of employer coverage.
• Get the full monthly COBRA premium—not merely the employee payroll deduction.
• Price Marketplace plans for the correct ages, ZIP code and household members.
• Verify doctors, hospitals and prescriptions directly with the plan.
• Estimate annual household MAGI, including full Social Security and taxable retirement withdrawals.
• Model at least three income scenarios: expected, lower and unexpectedly higher.
• Leave room for dividends, capital gains and other surprises.
• Decide how much of the estimated credit to take in advance.
• Report material income or household changes promptly.
• Plan the transition to Medicare several months before age 65.

The gap is a planning problem, not an automatic barrier

Health insurance before Medicare is expensive enough to deserve serious planning. It does not automatically mean you must keep working until 65.

An early-retirement plan becomes stronger when it gives healthcare its own budget, calculates Marketplace MAGI separately from spending and coordinates withdrawals across account types. For some households, the result will be a substantial subsidy. For others, COBRA, spouse coverage or paying full price may be the better answer.

Run the numbers before giving notice—not after the final paycheck.
