5-Year Pre-Retirement Checklist for $1M–$5M Investors: 2026 Edition

The five years before you stop working are the highest-leverage planning window you'll ever have. Contributions are at lifetime maximums, the Roth conversion window opens wide, and the decisions you make now about Social Security, healthcare, and asset location will shape your taxes for the next 30 years. Most people treat this window as a countdown. It's actually an opportunity.

Why this window is different

Between age 55 and retirement, several things align at once:

• Catch-up contributions kick in at 50. A 58-year-old couple maxing out every account — 401(k) with catch-up, IRA with catch-up, and HSA with catch-up — can shelter over $78,000 in pre-tax or Roth dollars per year. That's more than twice the contribution room available at 35.
• The Roth conversion window hasn't fully opened yet. Your last high-income years are actually the wrong time to convert. But retirement at 65 — before RMDs and before Social Security maximizes — is the sweet spot. Planning for that window starts now.
• You're close enough to see the numbers clearly. Your Social Security estimate is meaningful. Your retirement spending is estimable. A real retirement readiness analysis can replace guesswork with a plan.
• Sequence of returns risk becomes material. A 30% market drop the year you retire is ten times more damaging than the same drop at 35. Preparing the portfolio for that risk requires structural changes you can't make the week you retire.

Year-by-year action framework

5 years out (ages 55–60 typically)

• Begin systematic Roth conversions at the margin — fill your current bracket to the top without crossing into the next. Lock in today's rate against tomorrow's RMD-inflated income.
• Max out HSA contributions and invest (don't spend) the balance. At 55, you can contribute an extra $1,000 catch-up. The account compounds tax-free and serves as a stealth retirement account for medical expenses.
• Run a full beneficiary audit — IRA, 401(k), life insurance, revocable trust. Stale beneficiary designations are the most common and costly estate planning error at this stage.
• Price your healthcare gap (see section below). The years between retirement and Medicare at 65 are the most dangerous underestimate in financial planning.

3–4 years out

• Ages 60–63: activate the super catch-up. For 2026, employees in this age band can defer up to $35,750 to their 401(k) ($24,500 base + $11,250 super catch-up).¹ This is $3,250 more than the standard 50+ catch-up and a permanent SECURE 2.0 feature.
• 2026 Roth catch-up mandate: If your prior-year W-2 income exceeded $150,000, your 401(k) catch-up contributions must go to a Roth sub-account starting in 2026 — no choice.² This means you'll owe current-year tax on those contributions. Plan your withholding accordingly. Verify your plan has a Roth option; a small number don't yet comply.
• Begin de-risking in taxable. Shift any overweight positions and rebalance toward your retirement target allocation using TLH opportunities to minimize tax drag.
• Review life insurance needs. Once your portfolio can support a surviving spouse without your income, term coverage may no longer be necessary. Dropping unnecessary premiums redirects cash to Roth conversions.

1–2 years out

• Finalize your withdrawal order: taxable accounts first, then traditional IRA/401(k), then Roth. This order minimizes lifetime taxes and preserves tax-free Roth growth longest.
• Decide on Social Security timing. For most $1M–$5M investors, delaying to 70 is the best hedge against longevity — but the right answer depends on health, survivor benefit strategy, and whether you can bridge the income gap from portfolio.
• Build an income floor. Identify how much of your retirement expenses will be covered by guaranteed income (Social Security, pension, annuity) vs. portfolio withdrawals. The portion that must come from portfolio is your sequence-of-returns risk exposure.
• Practice your budget. Twelve months before retirement, live on your projected retirement income. The gap between your estimate and reality is data — and correctable while you're still working.

Catch-up contribution maximization (2026)

Here's the full contribution picture for a couple both age 55–63 in 2026:

That's nearly $90,000 per year sheltered by a couple fully utilizing every account. If they're in the 24% bracket, that's $21,600/year in federal tax avoided — plus state income tax. Over 4 years, the compounding benefit runs into six figures.

The Roth conversion window: your 5–15 year opportunity

Your last working years are generally the wrong time for large Roth conversions — you're in the 24%–32% bracket, and conversions layer on top of your salary. But the window that opens at retirement — before Social Security starts and before RMDs begin — is the most tax-efficient conversion period of your financial life.

Here's the sequence a $1M–$5M investor often experiences:

1. Retirement at 60–65. Earned income stops. Taxable income drops to dividends, interest, and whatever you pull from accounts.
2. Low-income gap years. Before Social Security and before RMDs, a married couple can have very low ordinary income. A couple converting $100K from a traditional IRA into Roth, with $32,200 standard deduction and no other ordinary income, pays tax only on $67,800 — at a blended rate of roughly 13–15%.
3. RMD age at 73 or 75 (SECURE 2.0).³ Once RMDs begin, plus Social Security (85% includible above the base threshold), your taxable income can spike to 32%–35% on forced distributions — even with no spending increase. Every dollar converted at 13–15% during gap years avoids 32%+ taxation at RMD time.

The planning takeaway: don't wait until retirement to plan the conversion window — do it now. Calculate your projected traditional IRA/401(k) balance at retirement, estimate the RMD income that generates, and work backwards to figure out how much conversion per year during gap years closes the gap. Use our Roth Conversion Sweet Spot Finder to model this.

Healthcare bridge: the gap nobody plans for

For early retirees (before 65), the healthcare gap is the most commonly underestimated cost. Medicare doesn't start at 60 or 62 — it starts at 65. The three bridge options and their tradeoffs:

• COBRA. Continuous with your employer plan. No underwriting. But you pay 100% of the full premium (employer + employee share) plus a 2% admin fee. For a family plan, this commonly runs $2,000–$3,000/month. Available up to 18 months.
• ACA Marketplace plan. After COBRA or if COBRA is too expensive. Premium tax credits phase out above 400% of FPL (~$84,600 for a couple in 2026). Important: Roth conversions increase MAGI and can eliminate ACA credits — a $20,000 conversion could cost $8,000+ in lost subsidies. Coordinate with your tax advisor. See the full analysis at Early Retirement Health Insurance.
• Spouse's employer plan. If your spouse continues working, this is usually the cheapest option — and a valid reason to sequence retirement dates carefully.

For IRMAA planning at Medicare start: if you have a large income event (big Roth conversion, business sale) in the two years before you turn 65, the IRMAA lookback will hit your Part B premium the moment you enroll. The 2026 first-tier IRMAA threshold is $109,000 for single filers ($218,000 MFJ).⁴ See our IRMAA tier calculator to check your exposure.

Social Security timing

For most $1M–$5M investors with reasonable health, delaying Social Security to 70 is the highest-return guaranteed investment available. The benefit grows 8% per year between FRA (67 for those born 1960+) and age 70 — and all those increases are permanent and inflation-adjusted.

The bridge question: can your portfolio fund living expenses from retirement to age 70 without Social Security? If you retire at 65 with $2M in investable assets, withdrawing $60K/year for 5 years while delaying SS is 15% of portfolio — very manageable. The delayed SS benefit increase of $6,000–$12,000/year typically pays back the portfolio withdrawal within 8–10 years.

For married couples: the higher earner should almost always delay to 70. The surviving spouse receives the higher of the two benefits for life — making the delay decision a longevity hedge for both partners.

Use our Social Security break-even calculator to model your specific case.

Sequence of returns risk: the structural fix

Sequence of returns risk is the phenomenon where a bear market in your first 5 years of retirement permanently impairs your portfolio — even if the long-term average return is fine. A 30% drop at 35 is just a paper loss. A 30% drop at 65 forces you to sell depressed assets to fund living expenses, leaving you with fewer shares to recover when markets rebound.

The structural fix is not "be more conservative" — it's building a spending buffer that doesn't require selling equities at trough prices:

• Cash/short-term bond bucket (1–2 years of expenses). Spend from this during down markets while equities recover. Refill when markets are up.
• Bond ladder (years 3–10). Individual bonds or bond ETFs laddered to mature annually as spending needs arrive.
• Equity bucket (10+ years). This money has time to recover from any market environment.

Start building these buckets 3–5 years before retirement. Doing it in a crash is called panic-selling.

Five things your advisor should be doing right now

If you're 5 years from retirement with $1M–$5M and your advisor is only managing your investment allocation, you are leaving significant money on the table. Here's what proactive planning at this stage looks like:

1. Roth conversion modeling. A detailed projection of your traditional IRA/401(k) balance at retirement, the RMD income stream that creates, and annual conversion targets to minimize lifetime tax. This isn't one number — it's a 15-year tax schedule.
2. Healthcare bridge plan. A year-by-year cost estimate of insurance from retirement to 65, with COBRA vs. ACA vs. spousal coverage modeled, and conversion amounts adjusted to preserve ACA eligibility if needed.
3. Social Security strategy. Not just break-even analysis — but coordinated claiming between spouses, survivor benefit optimization, and bridge funding from portfolio modeled against longevity scenarios.
4. IRMAA management. A two-year forward look at MAGI — which large events (conversions, asset sales, RMDs) would tip you into higher Medicare surcharge tiers — and a plan to smooth income across years to minimize IRMAA cost.
5. Sequence of returns mitigation. A concrete bucket or floor-and-upside strategy, not just an allocation shift, with a spending policy that prevents forced selling in down markets.

If this isn't happening at your current advisor, it's worth evaluating your options. Our advisor selection guide covers what fee-only advisors specializing in pre-retirees should be able to demonstrate in a first meeting.
