Retiring at 63 With an 82% Equity Portfolio and a Two-Year Health Insurance Gap
Married couple, ages 61 and 59, both still working. Combined salary $138,000. Investable assets $2.55 million: $1.53 million in traditional 401(k)s, $380,000 in Roth IRAs, and $640,000 in a joint taxable account carrying $285,000 of unrealized gain. Home worth $760,000, mortgage $185,000 at 3.10% with 11 years remaining. No other debt, no dependents. The portfolio is 82% equities, and last March, after a 15% drawdown, they sold $200,000 of stock and have not reinvested. Target spending is $105,000 per year after tax beginning when the older spouse turns 63. Social Security at full retirement age 67 is projected at $54,000 combined; the higher earner's own benefit is $31,000 at 67 and $41,000 at 70. They want to know whether the plan works and what to fix first.
1. Test whether retirement at 63/62 with $105,000 of after-tax spending is supportable. Show the arithmetic and identify the binding constraint.

Gross-up. $105,000 of after-tax spending requires roughly $120,000-$130,000 of pre-tax withdrawals depending on the mix of taxable, tax-deferred, and Roth dollars. Against $2.55 million that is an initial withdrawal rate near 4.7%-5.1%, not the 4.1% the client is mentally using.
The early years are the constraint, not the average. Social Security does not begin until 67, so ages 63-66 require the portfolio to carry the entire budget. That is four years of roughly 5% draws immediately after a drawdown year in which they already demonstrated they will sell at the bottom.
Longevity. For a 30+ year joint horizon, ~5% is above what an 82/18 portfolio reliably sustains without spending flexibility.
What to fix, in order:
- Build a 3-year spending reserve (cash, T-bills, short Treasuries) so equities are never sold in a down year; fund it inside the 401(k)s to avoid realizing gain.
- Delay the higher earner's benefit to 70. That is a $10,000/year real, inflation-adjusted increase for life and the cheapest longevity insurance available.
- Stress-test spending at $90,000 and $120,000. The plan works if discretionary spending can flex; it fails if it cannot.
- Do not treat the 4% rule as a pass/fail; report a probability range and the failure mode.
2. They sold $200,000 of equities during the drawdown. What structural changes address sequence-of-returns risk and asset location?

The sale is a symptom of a portfolio with no defined withdrawal source, not a risk-tolerance problem.
Build a liability-matching sleeve. Two to three years of net spending need ($250,000-$300,000) in short-duration, high-quality fixed income, replenished annually from whichever asset class is overweight. Refill in up, spend in down.
Asset location:
- Bonds and the cash reserve belong in the traditional 401(k), where interest is otherwise taxed at ordinary rates and RMDs will force distributions anyway.
- Equities belong in the Roth (never taxed, no RMDs, best asset for heirs) and in the taxable account (qualified dividends, step-up at death).
- Do not hold municipal bonds in the 401(k) or Treasuries in the Roth.
Rebalance inside the tax-deferred accounts. Their 82/18 drift should be corrected by shifting 401(k) dollars, not by selling the taxable account and triggering the $285,000 gain.
Behavioral guardrail: a written investment policy statement naming the rebalancing bands and the withdrawal source order. Their March sale happened because the only liquid assets were equities - the fix is mechanical, not educational.
3. How should they use the taxable account's $285,000 gain and any Roth conversion capacity between retirement and age 73?
Read the worked answer
The gap years are the most valuable tax planning window they will ever have, and there are three competing uses that cannot all be maximized.
1. Ages 63-64: health insurance dominates. Before Medicare, premium tax credits are based on MAGI. A large Roth conversion or gain realization in those two years can cost more in lost premium assistance than the conversion saves. Harvest gains at 0% long-term capital gains only up to the point where MAGI stays under the credit cliff they are targeting - compute it before converting a dollar.
2. Ages 65-72: convert aggressively, but watch the two-year IRMAA lookback. Medicare premiums at 65 are set from the return filed two years earlier, so a conversion at 63 has already been priced into age-65 premiums. From 65 onward, convert to the top of the 22% or 24% bracket while respecting the IRMAA tier edges, which act as a stealth surtax.
3. Harvest gain in the same years. At 0% federal capital gains rate, they can realize roughly the amount that fills the 0% bracket, immediately repurchasing to reset basis. This is free basis step-up while alive.
Sequence rule: never convert past an IRMAA or credit cliff for the sake of filling a bracket, and never convert dollars that will be spent within three years.
