A 56-year-old former tech founder walks away from her company with $4.2 million spread across four buckets: a $1.8 million traditional 401(k), a $900,000 Roth 401(k), a $180,000 HSA, and a $1.32 million taxable brokerage. She wants to spend $180,000 a year from age 56 through 65, then turn on Social Security. The money is there. The question is how to pull it out without handing a third of it back to the IRS.
This is a common problem. Tech founders, sales executives with vested RSUs, and dual-income professionals frequently arrive at their fifties with most of their wealth in tax-deferred accounts and appreciated stock. The instinct is to start drawing from the 401(k) because it is the biggest pile. That instinct is expensive.
The Setup at a Glance
- Age: 56, married filing jointly, planning a 10-year drawdown
- Assets: $1.8M traditional 401(k), $900K Roth 401(k), $180K HSA, $1.32M taxable brokerage, plus a Roth IRA aged more than 10 years
- Annual spending target: $180,000
- Bridge horizon: Ages 56 to 65, before Social Security and Medicare
Why a Decade Near Zero Tax Is Actually Possible
The 0% long-term capital gains bracket is the engine here. Most working professionals never access it. For 2026, a married couple pays 0% federal tax on long-term gains as long as taxable income stays at or below $96,700. Stack the $32,200 standard deduction on top, and the gross income that fits inside the 0% band is meaningfully higher.
Combined with HSA reimbursements (tax-free) and Roth contribution-basis withdrawals (tax-free under Roth ordering rules, even before 59.5), a household pulling $180,000 a year can owe under $1,500 in combined federal tax.
The four-bucket stack looks like this:
- $90,000 from the taxable brokerage by selling long-held positions. Cost basis trims the realized gain, and what remains slots inside the 0% LTCG band. Standard deduction absorbs ordinary income, keeping the brokerage withdrawal inside the 0% band.
- $30,000 from the HSA, reimbursed against stockpiled medical receipts from working years. Tax-free in, tax-free out, no age penalty. $30,000/year of receipts covers a decade of drawdowns if the receipt pile was maintained.
- $60,000 from the Roth IRA, withdrawing only contribution principal. Roll the Roth 401(k) into the existing Roth IRA at retirement so basis becomes accessible under ordering rules. Penalty-free before 59.5 because Roth ordering rules treat basis withdrawals as already-taxed money.
- $30,000 traditional-to-Roth conversion on top, deliberately taxable. The standard deduction absorbs nearly all of it, so the conversion happens at roughly a 0% effective rate while shrinking future required minimum distributions.
The Real Tradeoffs Behind the Strategy
Two materially different paths exist, and one is clearly better for most founders in this situation.
Path A: Run the four-bucket stack as designed. This is the right path for almost anyone with assets distributed like hers. It uses every tax-free lane the code offers, shrinks the traditional 401(k) before RMDs hit at 75, and keeps Roth earnings compounding untouched. The catch: it requires airtight cost basis records on the brokerage and disciplined receipt tracking on the HSA. A sloppy basis record can turn a 0% gain into a 15% gain with one bad spreadsheet.
Path B: Front-load larger Roth conversions. Push conversions to $80,000 to $100,000 a year and pay 10% to 12% on the excess. This makes sense only if she expects materially higher tax brackets later, or if the traditional 401(k) is so large that future RMDs would force her into the 24% bracket anyway. With $1.8 million in traditional and 19 years until RMDs, she is on the edge of needing this. Worth modeling, not automatic.
Path C: Drain the traditional 401(k) first. This is inferior. Every dollar pulled gets taxed as ordinary income and wastes the 0% LTCG band entirely. Avoid.
Two Things to Watch and One Mistake to Skip
The economic backdrop supports the plan. The 10-year Treasury at 4.4% means the cash and short-bond sleeve actually earns something while she waits to spend it. The VIX near 17 and a positive 0.5% 10Y-2Y spread argue against panic de-risking in year one. CPI sitting at the 90th percentile of its 12-month range is the bigger concern: a $180,000 budget today will buy meaningfully less in 2035, so build in a cost-of-living step-up.
The single most important deadline: finish all Roth conversions before age 63. IRMAA, the Medicare premium surcharge, uses a two-year MAGI lookback when she enrolls at 65. A conversion at 63 or 64 raises Medicare premiums for her first year on the program, sometimes by thousands of dollars. Conversions at 56 through 62 do not. That is the calendar that matters.
The common mistake to skip: tapping the traditional 401(k) for convenience in year one. Doing so wastes the 0% LTCG band that only exists while taxable income is low. Once Social Security and RMDs arrive, that band is gone for good.
