Overview

Retiring before age 65 creates an insurance and income gap: Medicare typically starts at 65, leaving early retirees responsible for health coverage and daily expenses for years or even decades. Bridge strategies are the tools and decisions you use to cover that interval. They combine health‑insurance choices, tax‑aware withdrawal plans, emergency cash reserves, and optional earned income to limit unexpected costs and preserve long‑term retirement assets.

In my practice working with early retirees, the most successful plans blend predictable cashflow with flexible contingency options. You’ll want to model several scenarios — good, base, and bad market returns — and test how each affects both your ability to pay premiums and your portfolio longevity.

This article explains practical bridge options, costs, how to sequence withdrawals, and common pitfalls to avoid. It also links to deeper guides on HSAs, Medicare timing, and Roth ladders for readers who want step‑by‑step help.

Why bridge strategies matter now

  • Healthcare is often the largest single expense for retirees before Medicare. Without employer coverage you can face premiums, deductibles, and out‑of‑pocket spending that rapidly erode savings.
  • Poorly planned withdrawals can trigger higher taxes, reduce future Social Security/Medicare means‑tested benefits, or produce penalties.
  • Sequence‑of‑returns risk: withdrawing the wrong assets during a market downturn can damage the portfolio’s ability to rebalance and recover. See our guide on Creating Income Bridges for Early Retirement for modeling tips.

Core bridge strategies

1) Health insurance options

  • COBRA: If you leave a job with employer coverage, COBRA can continue the same plan for typically up to 18 months (longer in certain situations). It is often the simplest short‑term option but can be expensive because you pay the full premium plus an administrative fee. The U.S. Department of Labor explains COBRA rules and timing: https://www.dol.gov/general/topic/health-plans/cobra.

  • Marketplace (Healthcare.gov): You can shop for ACA Marketplace plans during a Special Enrollment Period after job loss or other qualifying events; premium tax credits may make marketplace coverage affordable depending on your income. See https://www.healthcare.gov/ for eligibility and subsidy calculators.

  • Short‑term/Gap plans: Short‑term plans are cheaper but often exclude preexisting conditions and limit benefits. Use them only as last‑resort, temporary cover while you secure more stable insurance.

  • Private/Medicare‑ready bridge plans: Some insurers sell short‑duration plans designed for pre‑65 adults planning to enroll in Medicare at 65. Compare plan networks and out‑of‑pocket maximums carefully.

  • Employer retiree or spousal coverage: If you are married, check whether a spouse’s employer plan allows late enrollment; these can be cost‑effective but vary widely by employer.

(Practical note: in client cases I often run a three‑year premium projection to compare COBRA vs. Marketplace plus projected healthcare spending.)

2) Health Savings Accounts (HSAs)

  • HSAs offer a triple tax advantage for those enrolled in a qualified high‑deductible health plan (HDHP): contributions are tax‑deductible, the account grows tax‑free, and qualified withdrawals for medical care are tax‑free. IRS Publication 969 details HSA rules: https://www.irs.gov/publications/p969.

  • Strategies: max out HSA contributions while working, invest HSA funds for growth, and preserve the HSA balance as a tax‑efficient medical reserve in early retirement. After age 65, HSA funds can be used for nonmedical expenses without penalty (but taxed as ordinary income), making HSAs a flexible bridge tool.

3) Tax‑aware withdrawal sequencing

  • Roth IRA ladder: Convert funds from a traditional IRA or 401(k) to a Roth IRA in planned increments, then withdraw converted amounts after the five‑year rule to fund early retirement expenses without penalty. This is a common bridge tactic but requires careful timing and tax planning. Our Roth ladder primer covers mechanics and timing: https://finhelp.io/glossary/roth-ira-ladder-for-early-retirement-basics/.

  • 72(t) Substantially Equal Periodic Payments (SEPP): This IRS rule allows penalty‑free withdrawals from IRAs/401(k)s before 59½ if taken as a series of substantially equal payments for 5 years or until age 59½ (whichever is longer). It’s inflexible and can lock you into a payment schedule; use it only with professional advice. IRS guidance on early distribution penalties: https://www.irs.gov/retirement-plans/retirement-topics-tax-on-early-distributions.

  • Tax‑efficient order of withdrawals: A typical sequence rules-of-thumb—taxable accounts first, then tax‑deferred, then tax‑free (Roth)—may change based on market conditions and your projected tax brackets. Model impacts of Roth conversions on Medicare Part B/D IRMAA income thresholds and tax withholding.

4) Short‑term earned income and part‑time work

Taking part‑time work or consulting can provide premium‑paying income, delay withdrawals, and help you maintain employer benefits for a limited window. This hybrid approach reduces portfolio exposure to market risk and can be scaled up or down.

5) Emergency reserves and cashflow smoothing

Keep 6–24 months of non‑investment cash for premium spikes or unexpected health costs. Laddering short‑term CDs or a cash management account preserves buying power while offering modest returns.

Illustrative cashflow plan (example)

Scenario: retire at 58, Medicare at 65 — 7‑year bridge.

  • Year 0–2: Use COBRA or employer retiree coverage while maximizing HSA contributions and keeping 12 months of emergency cash. Limit withdrawals to taxable account gains (low capital‑gain tax) to avoid pushing into higher brackets.

  • Year 3–5: Start Roth conversions in small amounts to fill projected taxable income gaps while staying below higher tax brackets. Consider part‑time consulting for 3–6 months per year to cover premiums if market returns are poor.

  • Year 6–7: Use Roth laddered funds and remaining taxable assets; enroll in Marketplace if COBRA ends and subsidies apply. By age 65, move to Medicare and use HSA funds for eligible premiums and cost‑sharing (where allowed).

This is simplified — run cashflow projections with conservative return assumptions and stress tests for market dips.

Common mistakes and misconceptions

  • Relying only on COBRA without modeling what happens when COBRA ends or becomes unaffordable.
  • Underfunding HSAs or using them for nonmedical expenses early in retirement, losing tax‑efficient growth.
  • Ignoring the five‑year Roth conversion clock; premature withdrawals can be taxed and penalized.
  • Not accounting for Medicare Income‑Related Monthly Adjustment Amounts (IRMAA) that increase premiums if your modified adjusted gross income (MAGI) is high. Social Security and Medicare guidance is available at Medicare.gov.

Taxes and Medicare interactions

Be mindful that Roth conversions and large taxable events in the years before Medicare enrollment can increase your MAGI, potentially raising Medicare Part B and D premiums through IRMAA. Coordinate conversions and withdrawals with projected Medicare costs and Social Security timing.

Practical checklist before you retire early

  • Model 10‑15 years of cashflow and healthcare spending under multiple market scenarios.
  • Price COBRA vs. Marketplace options and calculate subsidy eligibility at Healthcare.gov.
  • Max out HSA while enrolled in an HDHP; invest HSA balances for long‑term growth.
  • Develop a withdrawal sequence that considers Roth conversions, 72(t), and taxable holdings.
  • Maintain an emergency cash cushion equivalent to at least 6 months of living expenses plus the annual premium.
  • Consult a CPA or certified financial planner to model tax impacts and ensure you meet Roth conversion and 72(t) requirements.

Final professional tips

In my practice I find that conservative assumptions about healthcare inflation (3–5% above CPI), a 15–20% buffer for premiums, and delaying large Roth conversions until you have a clear, multi‑year tax plan help avoid costly surprises. Use HSA funds strategically: treat them as your dedicated medical reserve and only tap investment gains once you have robust cashflow elsewhere.
