How to Afford Health Insurance If You Retire Before Medicare

Picture two very different people facing the exact same problem. A physician in her late fifties who's ready to step away from clinical practice after three decades. And a business owner in his mid fifties who just closed on the sale of the company he spent twenty years building. Neither one is old enough for Medicare. Both of them are staring at a health insurance bill that could run well over a thousand dollars a month before any subsidy, and neither one has an employer plan waiting to catch them.

This gap, the years between when you stop working and when Medicare eligibility begins at 65, trips up more early retirees and business sellers than almost any other planning issue. It's also one of the most solvable problems in your entire financial plan, provided you understand how the pieces fit together well before you actually walk away from work or sign a closing document.

What the Coverage Gap Actually Is

Medicare eligibility generally begins at age 65. If you retire or sell your business before that age and you don't have access to an employer sponsored plan, you have three realistic paths to bridge the gap & maintain health insurance coverage. You can continue your prior employer's coverage temporarily through COBRA. You can join a working spouse's employer plan if one is available to you. Or you can purchase a plan through the Affordable Care Act Marketplace.

Each of these paths has a different cost structure, and the Marketplace is the only one of the three where your income can meaningfully reduce what you pay. That last point is where most of the planning opportunity, and the planning risk, actually lives.

The ACA Subsidy Cliff and Why It Returned in 2026

For several years, temporary enhanced subsidies made ACA Marketplace coverage more affordable across a wider range of incomes than the program's original design allowed. Those enhanced subsidies were not extended beyond the end of 2025, which means the program's original rule is back in effect for 2026 coverage. Under that original rule, your eligibility for a premium tax credit is generally tied to your household income relative to the federal poverty level, and specifically to a threshold set at 400% of the federal poverty level.

The word "cliff" here is not an exaggeration. This isn't a gradual phase out. If your modified adjusted gross income, generally referred to as MAGI, falls even slightly above that 400% threshold, you can lose the entire premium tax credit for the year, not just a portion of it. A household sitting comfortably under the line one year and slightly over it the next can see their monthly premium jump by hundreds or even over a thousand dollars, with no advance warning built into the system.

What Counts Toward Your MAGI and What Doesn't

This is where the planning conversation actually happens, and it's also where physicians and business owners tend to have more moving pieces than the typical early retiree.

Generally speaking, withdrawals from traditional retirement accounts, capital gains from the sale of investments or a business, rental income, and most other forms of taxable income count toward your MAGI for ACA purposes. Qualified withdrawals from a Roth IRA generally do not, since they're not included in your adjusted gross income in the first place. This distinction matters enormously when you're deciding which accounts to draw from during your bridge years, since the source of your income can be just as important as the amount.

Bridging the Gap on a Physician's Compressed Retirement Timeline

Physicians tend to retire earlier than many other professionals, particularly in specialties with significant physical demands, and burnout has only accelerated that pattern in recent years. That earlier retirement date often means a longer bridge to Medicare, sometimes seven years or more, which makes managing MAGI during those years a bigger factor in the plan rather than a minor detail.

The sequence in which you draw from taxable brokerage accounts, tax deferred retirement accounts, and Roth accounts during this stretch can meaningfully affect where your household lands relative to the subsidy threshold each year. This is a genuinely technical coordination problem, one that touches your withdrawal strategy, your tax bracket management, and your health insurance costs all at once, and it's exactly the kind of decision that benefits from being modeled out in advance rather than figured out reactively each January.

When Your Business Sale Creates the Income Spike

If you're a business owner planning your exit, this section deserves your full attention, because your situation is structurally different from a physician drawing down a retirement portfolio gradually.

A business sale often produces one enormous capital gain concentrated in a single tax year, sometimes the very year you're also trying to bridge to Medicare. That combination can blow through the 400% subsidy threshold immediately and eliminate any premium tax credit entirely for that year, even if your income in every other year of your retirement would have qualified you for meaningful assistance. The timing and structure of your sale, whether it closes as a single lump sum, an installment sale spread across multiple years, or some other structure, has a direct and sometimes underappreciated effect on your health insurance costs during exactly the years you're relying on that sale to fund your lifestyle.

A single year of unusually high income, whether from a business sale or a large retirement account withdrawal, can eliminate thousands of dollars in annual health insurance subsidies in one move.

How a Well Funded HSA Lowers Your Bridge Year Costs

One of the most useful tools for this entire bridge period is one most people already have access to while they're still working, and most underuse. A Health Savings Account offers a rare combination of tax benefits. Contributions generally reduce your taxable income in the year you make them, growth inside the account is generally tax free, and withdrawals for qualified medical expenses are generally tax free as well, at any age, with no requirement to spend the funds in the year you contribute.

For 2026, an eligible individual can generally contribute up to $4,400 to an HSA, or $8,750 for family coverage, with an additional $1,000 catch up contribution available once you turn 55. Funded aggressively during your working years, an HSA can grow into a meaningful reserve by the time you retire, one that's earmarked specifically for medical costs and available to you tax free regardless of your income at the time you withdraw it.

That reserve changes the calculus when you're choosing a Marketplace plan during your bridge years. A higher deductible plan generally carries a lower monthly premium than a richer plan, and for 2026, Bronze and Catastrophic plans purchased on the Marketplace are generally treated as HSA compatible regardless of whether they meet the traditional HDHP deductible requirements. If you've built a substantial HSA balance in advance, a higher deductible plan becomes far less intimidating, since you already have tax free dollars set aside to absorb the larger out of pocket exposure, and you're not choosing a leaner plan out of necessity so much as by design.

Comparing Your Bridge Options

COBRA

COBRA lets you continue your prior employer's exact plan and network, generally for up to 18 months, but you're responsible for the full premium plus an administrative fee, with no subsidy available. It can make sense as a short term bridge, particularly if you're mid treatment with a provider you don't want to switch away from. For long term needs though, COBRA can be expensive compared to other types of plans.

A Spouse's Employer Plan

If your spouse is still working and has access to employer sponsored coverage, adding yourself to that plan is often the lowest cost option available, since the employer is typically subsidizing a meaningful portion of the premium regardless of your income.

The ACA Marketplace

The Marketplace is the only path of the three where your income can reduce your premium through a subsidy, which also makes it the option most directly affected by the MAGI planning discussed above.

What to Know Going In

• Medicare Eligibility: Coverage generally begins at age 65, meaning anyone retiring or exiting a business earlier needs a bridge strategy.
• The Subsidy Cliff: Temporary enhanced ACA subsidies were not extended beyond the end of 2025, returning the program to its original 400% federal poverty level eligibility threshold for 2026 coverage.
• 2026 HSA Contribution Limits: Eligible individuals can generally contribute up to $4,400 for self only coverage or $8,750 for family coverage, plus an additional $1,000 catch up contribution once you turn 55.
• COBRA Duration: COBRA continuation coverage is generally available for up to 18 months following a qualifying event such as retirement.

Federal poverty level figures, subsidy thresholds, and program rules are updated annually and can change with legislation. Confirm current year figures directly at healthcare.gov or with a licensed insurance professional before making coverage decisions.

Where This Fits Your Broader Financial Plan

Health insurance cost during your bridge years shouldn't be treated as a separate line item you figure out after every other decision is made. It belongs in the same conversation as your retirement account withdrawal sequencing, your Roth conversion timing, and for business owners, the structure and timing of your sale itself. Getting the order of operations right can be the difference between a bridge that costs you a few hundred dollars a month and one that costs you several times that, for the exact same underlying income.

Does selling my business affect my ACA subsidy eligibility?

Generally yes. The capital gain from a business sale typically counts toward your modified adjusted gross income, and a large gain concentrated in one tax year can push you above the subsidy threshold for that year even if your income in surrounding years would qualify.

What counts as income for ACA subsidies in retirement?

Generally, withdrawals from traditional retirement accounts, capital gains, rental income, and most other taxable income sources count. Qualified Roth withdrawals generally do not, since they aren't included in adjusted gross income.

Is COBRA or the ACA Marketplace better for early retirees?

It depends on your circumstances. COBRA preserves your existing plan and network without underwriting, but at full premium cost which can be expensive.The Marketplace is generally less expensive if you qualify for a subsidy, but may involve a different provider network.

How long does the Medicare coverage gap typically last for early retirees?

It depends entirely on your retirement age. A physician retiring at 58 faces a seven year bridge to Medicare eligibility at 65, while someone retiring at 63 faces only two years.

Can I use my HSA to pay for a Marketplace plan during early retirement?

Generally, HSA funds can be used tax free for qualified medical expenses such as deductibles, copays, and coinsurance, but generally not for Marketplace premiums themselves. A well funded HSA still helps considerably, since it may let you comfortably choose a higher deductible, lower premium plan while covering the larger out of pocket exposure with tax free dollars.

Most fee only financial advisors treat health insurance as an afterthought in the retirement conversation, something to sort out closer to the date rather than something to model years in advance. For physicians and business owners with complex, sometimes concentrated income sources, that approach leaves real money on the table. At Oread Wealth Partners, we build this directly into the retirement and exit planning work we do with clients, so the timing of your income and the cost of your coverage are planned together rather than discovered separately.
