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](RetirementAccountWithdrawalRules). 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**:

- Cover living expenses from **taxable accounts** (capital gains may be taxed at 0% if income is low enough) and/or **Roth contributions** (always tax-free and penalty-free)

- Simultaneously execute **Roth conversions** to fill low tax brackets (see [Roth Conversion Strategy](RothConversionStrategy))

- The conversions are taxable income, but you're controlling the amount to stay in the 10-12% bracket

**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**:

- Social Security covers a portion of expenses

- Fill remaining needs from **taxable accounts** or **Roth**

- Continue Roth conversions, but now you have less bracket space because Social Security is partially taxable

- Model the interaction: Roth conversion income can push more of your Social Security above the taxability thresholds

**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**:

- Take RMDs from **Traditional IRA** (mandatory — see [Required Minimum Distributions](RequiredMinimumDistributions))

- If RMDs plus Social Security don't cover all expenses, draw the remainder from **Roth** or **taxable**

- **Stop** Roth conversions if RMDs already push you into higher brackets

- Consider Qualified Charitable Distributions (QCDs) to satisfy RMDs without increasing taxable income

**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.

**Strategy**:

- Let RMDs drive Traditional IRA withdrawals

- Use **Roth** for large unexpected expenses (healthcare, home modifications) to avoid tax spikes

- **HSA** funds (if available) for qualified medical expenses — tax-free (see [Health Savings Accounts](HealthSavingsAccounts))

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 Source | Amount | Running 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 $96,700 | 0% |

| $96,701 - $600,050 | 15% |

| Above $600,050 | 20% |

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

| Situation | Draw From | Why |

|-----------|----------|-----|

| Low-income year, no RMDs | Taxable + Roth conversions | Maximize low-bracket conversions |

| RMDs cover expenses | Take RMD only, no other withdrawals | Don't add unnecessary income |

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

| Large one-time expense | Roth (if available) | Avoids tax spike and potential IRMAA trigger |

| Charitable giving year | QCD from Traditional IRA | Satisfies RMD without taxable income |

| Healthcare expense | HSA first, then Roth | Both are tax-free for medical expenses |

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.
