Retirement Withdrawal Sequencing

You've spent decades filling different buckets: taxable brokerage, Traditional 401(k)/IRA, Roth IRA, maybe an HSA. Now you need to empty them. The order you choose can easily mean a six-figure difference in lifetime taxes.

For the rules governing each account type, see Retirement Account Withdrawal Rules. This article covers strategy — how to sequence withdrawals to minimize taxes across a multi-decade retirement.

The Conventional Wisdom (And Why It's Often Wrong)

The standard advice is:

  1. Spend taxable accounts first (capital gains taxed favorably)
  2. Then spend Traditional IRA/401(k) (taxed as ordinary income)
  3. Spend Roth IRA last (tax-free, grows longest)

This ordering is simple and directionally sensible. But it ignores the most important variable: your tax bracket changes across retirement phases, and you can exploit those changes.

Why the Conventional Order Fails

Following the conventional order means you leave your Traditional IRA untouched for years while it grows. By the time RMDs force distributions at age 73, the account may be so large that the forced withdrawals push you into the 22% or 24% bracket — even if you spent your early retirement years in the 10% or 12% bracket.

You had years of low-bracket capacity that went unused.

The Phase-Based Approach

Instead of a fixed order, match your withdrawal source to your tax situation in each retirement phase.

Phase 1: Early Retirement to Social Security (Ages 55-67)

Tax situation: No employment income, no Social Security, no RMDs. Your taxable income is near zero.

Strategy:

Why this works: You're drawing living expenses from sources that generate little or no tax, while converting Traditional IRA money at rock-bottom rates. Every dollar converted is a dollar that won't be forced out later at a higher rate.

Phase 2: Social Security Begins, Before RMDs (Ages 67-72)

Tax situation: Social Security adds taxable income (up to 85% of benefits are taxable above certain thresholds). Traditional IRA still growing.

Strategy:

Key calculation: For every $1 of conversion income above the Social Security taxation thresholds, up to $0.85 of additional Social Security becomes taxable. The effective marginal rate on conversions is higher than the stated bracket.

Phase 3: RMD Years (Ages 73+)

Tax situation: Required minimum distributions force taxable income from Traditional accounts. Combined with Social Security, your floor taxable income may already be substantial.

Strategy:

Important: If you executed Roth conversions effectively in Phases 1-2, your Traditional IRA is smaller now, producing smaller RMDs. This is the payoff.

Phase 4: Late Retirement (Ages 80+)

Tax situation: RMD percentages increase each year (from ~3.8% at 73 to ~8.8% at 90). Healthcare costs may increase.

Tax Bracket Management in Practice

The "Fill the Bracket" Technique

Each year, calculate how much income you can realize before crossing into the next tax bracket. Then deliberately realize that much.

Example: Married couple, 2026

Income SourceAmountRunning Taxable Income
Standard deduction-$30,000-$30,000
Social Security (85% taxable)+$25,500-$4,500
RMD+$35,000$30,500
Remaining 12% bracket space$66,450$96,950
Roth conversion to fill bracket+$66,450$96,950

The couple converts $66,450 to Roth at the 12% rate ($7,974 tax). Every dollar they don't convert now will eventually come out as an RMD — likely at 22% or higher as the account grows and RMD percentages increase.

Capital Gains Rate Optimization

Long-term capital gains and qualified dividends have their own bracket structure:

Taxable Income (MFJ)LTCG/QD Rate
Up to $96,7000%
$96,701 - $600,05015%
Above $600,05020%

In years when your ordinary income is low, you can harvest capital gains from your taxable account at the 0% rate. This is essentially free tax on investment growth — but only if your ordinary income (including Roth conversions) stays below the threshold.

Coordination required: Roth conversions and capital gains harvesting compete for the same low-bracket space. In any given year, decide which is more valuable.

Withdrawal Sequencing Decision Matrix

RMDs fall short of needsRMD + Roth (to avoid higher bracket)Roth withdrawal doesn't increase taxable income

Common Sequencing Mistakes

  1. Spending all taxable first: Leaves the Traditional IRA growing unchecked, creating a larger RMD problem later.
  2. Ignoring Roth conversions during gap years: The lowest-tax window of your life, wasted.
  3. Converting too much in one year: Triggers IRMAA, pushes capital gains into 15%+ bracket, or causes more Social Security to become taxable.
  4. Treating Roth as "emergency only": Roth is best used strategically to manage taxable income, not just hoarded.
  5. Not coordinating with spouse: One spouse's withdrawal plan affects the joint tax return.
