Health Coverage Costs From Early Retirement Through Medicare

Retiring before 65 means bridging to Medicare with COBRA, a spouse's plan, or ACA coverage; after 65, income drives Medicare surcharges (IRMAA).

Health Coverage Costs From Early Retirement Through Medicare

1 / 7

The short answer

  • Health costs in retirement fall into two stages: bridging coverage until Medicare at 65, then Medicare premiums and out-of-pocket costs.
  • Before 65, the main options are COBRA, a working spouse's plan, employer retiree coverage, or an ACA marketplace plan.
  • Your taxable income affects costs in both stages, through ACA subsidies before 65 and Medicare surcharges after.
  • Long-term care is a separate risk that neither employer plans nor Medicare cover for extended custodial care.

The short answer

  • Health costs in retirement fall into two stages: bridging coverage until Medicare at 65, then Medicare premiums and out-of-pocket costs.
  • Before 65, the main options are COBRA, a working spouse's plan, employer retiree coverage, or an ACA marketplace plan.
  • Your taxable income affects costs in both stages, through ACA subsidies before 65 and Medicare surcharges after.
  • Long-term care is a separate risk that neither employer plans nor Medicare cover for extended custodial care.

What are the options before Medicare?

  • COBRA generally continues your employer plan for up to 18 months, at up to 102% of the full premium.
  • Joining a working spouse's employer plan is often simpler, and losing other coverage opens a special enrollment period.
  • ACA marketplace plans accept anyone during open enrollment or after a qualifying event, without underwriting for health conditions.
  • Starting in 2026, bronze and catastrophic marketplace plans are treated as HSA-compatible under the July 2025 tax law.

How do ACA subsidies depend on income in 2026?

  • The IRS describes the enhanced premium tax credits as a temporary expansion for tax years 2021 through 2025; check HealthCare.gov for current rules.
  • For 2026 coverage, subsidies are again limited to households at or below 400% of the federal poverty level.
  • For a household of two in the 48 contiguous states, that cutoff is about $84,600 of modified AGI, and exceeding it by one dollar ends eligibility.
  • Income from Roth conversions, capital gains, and stock sales counts, so the timing of those events matters.

What drives costs after 65?

  • Medicare Part B and Part D premiums rise with income through IRMAA, based on modified AGI from two years earlier.
  • For 2026, IRMAA begins above $109,000 for single filers and $218,000 for joint filers; thresholds are adjusted annually for inflation.
  • Tax-exempt municipal bond interest counts toward the IRMAA income measure, even though it is not taxed federally.
  • HSAs cannot receive contributions once you enroll in Medicare, but existing balances can pay many Medicare premiums tax-free.

Income moves that can help manage these costs

  • Spreading Roth conversions or stock sales across years can help keep income below ACA or IRMAA thresholds in key years.
  • At 70½ and older, qualified charitable distributions from an IRA, up to $111,000 in 2026, are excluded from income.
  • QCDs must go directly from the IRA to an operating charity; donor-advised funds do not qualify.
  • Lower income in one area can raise taxes in another, so model the full picture with a CPA.

How do people approach long-term care?

  • Medicare covers limited skilled nursing care, not long-term custodial help with daily activities.
  • Traditional long-term care insurance can have premium increases over time, while hybrid life policies offer fixed premiums with different trade-offs.
  • Premiums for tax-qualified long-term care policies can count as medical expenses, up to age-based IRS limits.
  • Some households with substantial assets choose to self-fund, accepting the risk of a long, expensive care need.

Key takeaways

  • Plan the bridge to 65 before you retire; coverage choices and deadlines start the day employment ends.
  • In 2026 the ACA 400% income cliff is back, which makes income timing important for early retirees.
  • Income two years before a given year sets that year's Medicare surcharges.
  • This is general education; confirm tax effects with a CPA and coverage details with plans or a licensed agent.
