Healthcare Bridge Before Medicare

What happens to your health insurance if you retire at 60? You buy it yourself for five years, because Medicare doesn’t start until 65 and the gap is on you. That bridge is the single most underestimated cost of an early retirement, and it’s also a tax decision in disguise.

The three ways across

You’ve basically got three options to cover the years between your last paycheck and Medicare:

• COBRA. You keep your employer’s plan, usually for up to 18 months, but you pay the full premium plus a small admin fee. It’s the same coverage you know, and it’s expensive because your employer stops subsidizing it. Good as a short bridge, rarely as a five-year one. See COBRA vs. marketplace coverage.
• The ACA marketplace. You buy an individual plan on the exchange. The premium depends on your plan and your income, and that income link is the whole game (more below). See the ACA bridge to Medicare.
• A spouse’s plan. If your spouse still works and has coverage, joining their plan is often the cheapest bridge of all. Cheap and simple beats clever.

The part most people miss: the bridge is taxable

Most people price the bridge as a premium and stop there. The second-order move is realizing that on the ACA marketplace, your premium is set by your income, and in early retirement you often control your income. Pull your spending from cash and taxable accounts, keep your reported income modest, and the subsidies can shrink the premium dramatically. Pull a big Roth conversion in the same year and you can blow past the subsidy cliff, turning a cheap year into an expensive one.

That’s the tension that defines these five years. The early-60s are also the best window for Roth conversions, while your income is naturally low and before RMDs begin. So you’re managing two dials at once: convert enough to drain the tax-deferred accounts, but not so much that you torch your health subsidy. There’s no clean answer that fits everyone, only a yearly trade-off you actually run. ACA subsidies for early retirees walks through the math.

If your accounts are large

When you’re sitting on several million, the ACA subsidy is often out of reach because your income or your conversions are simply too high to qualify, and chasing it can cost you more than it saves. For these households I’d usually stop optimizing the premium and start optimizing the bracket: pay full freight for a strong plan, then use these low-income pre-Medicare years to convert aggressively at today’s rates, knowing IRMAA, the income-based Medicare surcharge, is waiting on the other side. The cushion is a tax window, not a discount. Price the five years honestly, run the income trade-off every year, and you turn the scariest line in an early retirement into one you control.
