Taxable accounts
Brokerage, savings, CDs. Gains taxed at favorable capital gains rates. Step-up in basis at death makes these efficient to spend first.
Tax-deferred accounts
Traditional IRA, 401(k). Every dollar taxed as ordinary income. RMDs will force withdrawals anyway — better to draw proactively at lower rates.
Tax-free accounts
Roth IRA, IUL loans. Zero tax on qualified withdrawals. No RMDs. Preserve as long as possible — use only in high-income years or for legacy.
Why the standard sequence is only a starting point
The standard order assumes a static tax situation. In reality, the optimal sequence changes every year based on your bracket headroom, RMD obligations, Social Security timing, IRMAA thresholds, and whether you are in a conversion window. A retiree in a low-income year should draw more from the tax-deferred bucket (or convert to Roth) — not less. The sequence is a framework, not a formula.
| Phase | Income situation | Optimal sequence adjustment |
|---|---|---|
| Early retirement (pre-SS, pre-RMD) | Low income — the golden window | Draw taxable first, aggressively convert IRA to Roth, harvest capital gains at 0% |
| Social Security begins | SS income raises combined income baseline | QCDs to reduce AGI, shift more to Roth distributions to avoid SS taxation |
| RMDs begin (age 73) | Forced income from traditional IRA | RMD satisfies bracket fill; supplement with Roth/IUL to avoid bracket overflow |
| High-bracket year | Large capital gain, sale, or inheritance | Draw from Roth or IUL loans — zero additional taxable income |
| Legacy planning phase | More income than needed | Maximize Roth conversions for heirs; fund IUL to pass wealth tax-free |
⚖️ Coordinate with RMDs every year
Once RMDs begin, they become the baseline of your tax-deferred withdrawal. Model whether your RMD alone fills your bracket — if it does, all other income should come from Roth or IUL. If it doesn't, fill the remaining bracket headroom with additional conversions or distributions before year-end.
🛡 Use Roth and IUL as the shock absorber
Keep Roth IRA and IUL cash value as a reserve for unpredictable high-income years — a large medical expense, a required lump sum, or an unexpected income event. Drawing from tax-free sources in these years prevents bracket spikes that would otherwise be unavoidable.
📅 Revisit annually — not once at retirement
Tax laws change, account balances shift, Social Security begins, RMDs start, and your needs evolve. The optimal withdrawal sequence for 2026 is likely different from 2028. An annual review with a tax-aware advisor is essential — not optional — for this strategy to work.
