Health Insurance Before Medicare: Planning the ACA Bridge for Early Retirees

The Health Insurance Gap Is the Biggest Early Retirement Risk

The question I heard from virtually every pre-Medicare early retiree was the same: 'What do I do about health insurance?'

This isn't a minor planning detail. Group employer coverage for a 60-year-old costs roughly $800-$1,200/month for a family of two if COBRA'd. At full cost (no subsidy), ACA marketplace plans for a 60-year-old non-smoker run $700-$1,100/month in most states. Over 5 years from age 60 to 65, full-cost coverage could run $42,000-$66,000 per person in premiums alone.

This single line item has derailed early retirement plans for clients who hadn't modeled it. And it's the piece that's most responsive to planning.

The federal premium tax credit under the ACA creates a sliding subsidy from 0% to 400% of the federal poverty level (FPL). Above 400% FPL, the American Rescue Plan Act temporary expansion through 2025 created additional subsidies — and as of this writing, the extension beyond 2025 is a policy variable to monitor. The planning lever: control your Modified Adjusted Gross Income (MAGI) to maximize subsidies.

MAGI Control: How Early Retirees Can Access Large Subsidies

MAGI for ACA subsidy purposes includes: taxable income, Roth conversion amounts, capital gains, Social Security benefits (in the year they begin), and IRA distributions. It excludes Roth IRA distributions (since those are tax-free) and certain other items.

The subsidy cliff example that makes this concrete:

2026 federal poverty level: approximately $15,650 (single), $21,150 (couple). 400% FPL: $62,600 (single), $84,600 (couple).

A single 62-year-old early retiree with MAGI of $58,000 might pay $150-$300/month in premiums after subsidy on a benchmark Silver plan. The same person with MAGI of $65,000 (above 400% FPL under non-ARP rules) could face $800+/month with no subsidy.

Strategies to control MAGI below 400% FPL: 1. **Roth conversions:** Roth conversions count as MAGI — but can be sized precisely to stay within the desired income threshold 2. **Capital gain harvesting:** Long-term capital gains are included in MAGI; timing large taxable events to avoid peak subsidy years 3. **Roth IRA distributions:** Withdrawals from Roth accounts are excluded from MAGI — this is the structural reason why Roth accounts are so valuable in the pre-Medicare gap

What Early Retirees Need to Know About Plan Selection

ACA plans are categorized as Bronze, Silver, Gold, and Platinum by their actuarial value (the share of covered health costs the plan pays on average).

**Silver plans have a special advantage:** cost-sharing reductions (CSRs) are only available on Silver plans. If your income is below 250% FPL (approximately $39,000 single in 2026), a Silver plan can have deductibles as low as $300 and out-of-pocket maximums of $1,500 — effectively functioning like a Platinum plan at Silver premiums. This is one of the most underutilized benefits in the ACA.

For early retirees managing income carefully, the Silver + CSR combination can provide excellent coverage at very low cost. But it requires keeping MAGI below the relevant threshold — which may mean accepting some tax inefficiency on conversions.

For healthy early retirees with higher incomes above the CSR threshold, High Deductible Health Plans (HDHP) paired with Health Savings Accounts (HSA) remain available on the marketplace. HSA contributions ($4,300 single, $8,550 family in 2026) reduce MAGI, create a triple-tax-advantaged account for medical expenses, and can be invested. Note: HSA contributions stop at Medicare enrollment.
