Retiring Before 65: How to Bridge the Health Insurance Gap Without Draining Your Plan

Most people treat the pre-Medicare gap as a health insurance problem. It is actually a tax problem wearing a health insurance costume. Get the tax layer wrong, and you will spend tens of thousands of dollars more than you have to before age 65 ever arrives.

COBRA Is Usually the Wrong Default

When you leave an employer, COBRA feels like the safe, familiar choice. It is often neither. COBRA lets you keep your existing coverage, but you pay the full premium your employer was subsidizing, plus a 2% administrative fee. For a family plan, that can run $2,000 to $2,500 a month or more. Sixty days of that and most people start looking for alternatives.

The ACA marketplace is frequently cheaper, sometimes dramatically so, because subsidies are available based on income, not assets. A couple retiring at 62 with $3 million in a brokerage account but modest taxable income can qualify for substantial premium tax credits. The benchmark: subsidies phase out when your Modified Adjusted Gross Income exceeds 400% of the federal poverty level, which for a two-person household in 2026 is roughly $83,000. Below that threshold, the savings are real and worth engineering around.

COBRA has one legitimate use case: you are in the middle of an expensive claims year, your deductible is nearly met, and switching mid-year would restart it. Outside of that narrow window, the math usually points elsewhere.

The Subsidy-Conversion Tension Is the Central Problem

Here is where early retirees collide with a genuine planning conflict. Roth conversions, which are often most valuable in the exact years between retirement and Medicare, directly increase your MAGI. Convert $60,000 in a year when your other income is low, and you might price yourself out of a meaningful subsidy, adding $12,000 or more in premiums to fund a conversion that saved you $14,000 in future taxes. The net advantage shrinks fast.

This tension is not a reason to skip conversions. It is a reason to sequence them carefully. The Soil layer of a retirement plan, the tax architecture built before the first withdrawal, is precisely where this gets mapped. The conversion amount, the timing within the year, the income from other sources, and the subsidy cliff all interact. There is no formula that works for everyone; the right answer depends on your bracket today, your bracket projection in retirement, and how much of your estate is pre-tax. The Sporos Doctrine treats this as a multi-year coordination problem, not an annual tax return question.

Your HSA, if you have one, belongs in this picture too. Funds already in an HSA can pay Medicare premiums and out-of-pocket costs tax-free, which means every dollar you spent building that account during your working years is now a clean, untaxed resource in the bridge period. If your spouse is still working and covered by an HSA-eligible plan, continuing to contribute and spend from that account extends its value further.

Spousal coverage through an employer plan is worth running the numbers on as well. If your spouse is still employed, joining their plan may be the simplest bridge available, often at a fraction of the open-market cost.

What to Do This Week

Pull together three numbers: your projected MAGI for each year until 65, your current HSA balance, and the cost of every coverage option available to you. Then look at where a Roth conversion would land you relative to the subsidy thresholds. The interaction between those figures is where the real planning lives.
