Most retirement planning conversations focus on accumulation: how much to save, which accounts to use, what to invest in. The withdrawal phase — which account to pull from first when the paycheck stops — gets far less attention, which is unfortunate because the tax consequences of getting it wrong are substantial and irreversible. Drawing too aggressively from a traditional 401k early in retirement can push you into a higher bracket unnecessarily. Letting your Roth IRA grow untouched for another 20 years while you pull from everything else is often the right move. But the specifics depend on your income mix, your Social Security timing, and a window between retirement and age 73 that most people either exploit deliberately or miss entirely.
The conventional withdrawal order taught in most financial planning books is: (1) taxable brokerage accounts first, (2) traditional 401k and IRA accounts second, (3) Roth IRA last. That framework is broadly correct — but it's a first approximation that ignores the most valuable tax-planning move available to early retirees: using the low-income years between retirement and Social Security to convert traditional IRA money to Roth at rock-bottom tax rates. The optimized withdrawal sequence at 62 looks different from the textbook, and the difference is worth tens of thousands of dollars for most households.
Why Withdrawal Order Matters: The Tax Multiplier
Every Account Type Has a Different Tax Treatment
Traditional 401k and Traditional IRA:
Contributions were made pre-tax. Every dollar withdrawn is taxed as ordinary income in the year of withdrawal. Required minimum distributions (RMDs) begin at age 73 — you must start taking money out whether you want to or not, at a rate determined by your balance and IRS life expectancy tables.
Taxable Brokerage Account:
Contributions were made with after-tax dollars. Withdrawals of principal are tax-free. Gains are taxed at long-term capital gains rates (0%, 15%, or 20% depending on income) if the investment was held over 12 months. Dividends are taxed in the year received regardless of whether you 'withdraw' them. No RMDs, no age restrictions, no early withdrawal penalties.
Roth IRA:
Contributions were made with after-tax dollars. All withdrawals — principal and growth — are completely tax-free after age 59½ (assuming the account has been open 5+ years). No RMDs during the account owner's lifetime. Zero tax obligation on all future growth, forever.
The strategic implication: you want to minimize how much ordinary income you recognize in any given year, because ordinary income triggers the highest rates. Roth withdrawals don't count as income. Long-term capital gains from taxable accounts are taxed at favorable rates (including 0% for lower-income retirees). Traditional account withdrawals are taxed at your full marginal rate — the same rate as your salary was taxed when you were working.
The Conventional Withdrawal Sequence and Why It's Incomplete
Textbook Order: Taxable → Traditional → Roth
The logic of the standard sequence:
1. Taxable first: Eliminates the annual tax drag from dividends and interest. Lets tax-advantaged accounts keep compounding without interruption. Capital gains on taxable accounts may be taxed at 0% if your income is low enough in early retirement (the 0% long-term capital gains bracket extends to $94,050 for married filing jointly in 2024).
2. Traditional 401k/IRA second: After depleting taxable accounts, begin systematic withdrawals from pre-tax accounts. By this point, you may be taking Social Security, which adds to your taxable income — so the traditional account distributions compound on top of Social Security, potentially pushing you into higher brackets.
3. Roth last: Roth grows tax-free indefinitely. Delay as long as possible to maximize tax-free compounding. No RMDs means you can let it grow past age 73 if you have other income sources.
This sequence is reasonable. It's also suboptimal for anyone who retires before Social Security starts and has significant traditional account balances headed toward large RMDs at 73.
The Missing Step: Roth Conversions During the Low-Income Window
Here's the move the standard sequence omits: if you retire at 62 and delay Social Security until 67 or 70, you have a 5-8 year window where your income is dramatically lower than it was while working — and dramatically lower than it will be after Social Security starts and RMDs kick in at 73.
During that window, you can convert chunks of your traditional 401k or IRA to Roth, paying tax at today's low rates instead of letting the balance compound further and face higher rates later. This doesn't change the 'withdrawal order' in the traditional sense — you're not spending the money — but it changes the future composition of your accounts and the lifetime tax bill on that money.
A married couple retiring at 62 with no Social Security yet can convert up to $94,300 + $29,200 (standard deduction) = $123,500 from traditional to Roth annually and stay entirely within the 12% bracket. At a blended effective tax rate of 8-9% on that conversion, they're permanently moving money from a future tax rate (potentially 22%+ once Social Security + RMDs compound) to a tax-free bucket at a fraction of the cost.
The Optimized Withdrawal Sequence at 62
Phase 1: Ages 62-70 (Before Social Security Starts)
Primary income source: Taxable brokerage account
Secondary move: Partial Roth conversions from traditional 401k/IRA
Goal: Live on taxable account cash flow while converting traditional account money to Roth at low rates
Why taxable first: At this income level (living on capital gains and brokerage withdrawals), the household may qualify for the 0% long-term capital gains rate on a significant portion of their taxable account gains. A couple with $94,050 or less in total taxable income (including the capital gains themselves) pays zero federal tax on those gains. This is one of the most underused tax benefits in the entire code — and it's available specifically to early retirees with low ordinary income.
Example — couple with $200,000 in taxable brokerage, 40% unrealized gains ($80,000 gain on $200,000 basis):
– Annual living expenses: $80,000
– Withdraw $80,000 from taxable (60% basis return, 40% gains = $32,000 capital gain)
– If total income stays under $94,050, the $32,000 in gains is taxed at 0% federal
– Plus: Convert $40,000 from traditional IRA to Roth during this year (now ordinary income, taxed at ~8-10%)
– Total federal tax bill: Approximately $3,200-4,000 on $120,000 in activity
That's a remarkably low tax rate for a couple drawing $80,000 in living expenses and moving $40,000 into a permanent tax-free account simultaneously.
Phase 2: Ages 70-73 (After Social Security Starts, Before RMDs)
Primary income source: Social Security (tax-advantaged, especially if benefits are modest)
Secondary source: Traditional 401k/IRA withdrawals (now more necessary as conversions wind down)
Roth: Still untouched, still growing
Once Social Security starts, income mechanics change. Up to 85% of Social Security benefits become taxable when provisional income (AGI + half of Social Security + tax-exempt interest) exceeds $44,000 for married filing jointly. Social Security at $3,000/month ($36,000/year) adds $30,600 in taxable income (85% of $36,000) at the common threshold. This pushes the optimal conversion amount lower — you're filling less bracket headroom because Social Security already occupies the lower brackets.
In this phase, drawing from traditional accounts at a controlled rate — enough to cover the gap between Social Security and living expenses, but not so much that you jump brackets — becomes the primary task.
Phase 3: Age 73+ (RMDs Begin)
Primary income source: Social Security + Required Minimum Distributions from traditional 401k/IRA
Roth: Now available as backup, still no RMDs, still tax-free
RMDs are calculated by dividing the December 31 balance of all traditional accounts by an IRS life expectancy factor (27.4 at age 73, declining annually). A $600,000 traditional balance at 73 generates a first-year RMD of approximately $21,900 — whether you need the money or not. That RMD is ordinary income, stacks on top of Social Security, and can push a couple into the 22% bracket involuntarily.
The goal of Phase 1 Roth conversions was precisely to reduce this balance before 73 — so the mandatory distributions are smaller and the forced tax bill is lower. Every $100,000 converted in Phase 1 (at 10-12%) reduces the future RMD obligation (which might hit at 22-24%) by that $100,000 plus all its subsequent growth.
A Concrete Example: Three Scenarios at 62
Starting Position
Couple, both 62, delaying Social Security to 70 (combined benefit: $4,000/month = $48,000/year at 70). Accounts: $500,000 traditional 401k, $200,000 taxable brokerage, $150,000 Roth IRA. Annual spending: $75,000.
Scenario A — Conventional sequence (taxable → traditional → Roth, no conversions):
Ages 62-65: Draw from taxable ($200k depleted in ~2.7 years at $75k/year)
Ages 65-70: Draw $75k/year from traditional 401k (taxed as income; $375k withdrawn)
Age 70: Social Security starts ($48k/year)
Age 73: Traditional balance ~$265,000 (after $375k withdrawals + growth). RMD: ~$9,700/year.
Tax character of income at 73: $48k SS + $9.7k RMD + traditional withdrawals as needed = likely 22% bracket
Estimated lifetime tax on traditional account: 22-24% average rate on remaining balance
Scenario B — Optimized sequence with Roth conversions:
Ages 62-70: Draw from taxable ($200k) + convert $40k-$50k/year from traditional to Roth
By age 70: Traditional balance reduced by ~$320k through conversions (paid at 10-12% avg rate)
Age 70: Social Security starts, traditional balance ~$230k (some growth offsetting conversions)
Age 73: Traditional balance ~$260k. RMD: ~$9,500/year (similar level, but much of the original $500k was converted at lower rates)
Roth IRA at 73 (after 11 years growth at 6%): ~$450,000+, zero RMDs, zero tax on withdrawals
Estimated lifetime tax saving vs Scenario A: $35,000-60,000 depending on rate assumptions
Scenario C — Early Roth withdrawal (worst approach):
Drawing from Roth IRA to fund living expenses at 62 because it requires 'no paperwork'
Result: Depletes the permanently tax-free account early while leaving the taxable account (with 0% capital gains opportunity) and the traditional account (with conversion window) untouched
Cost: Loss of years of tax-free Roth compounding; missed 0% capital gains window; missed conversion window
ACA Health Insurance: The Income Management Complication Before Age 65
One additional factor at 62-64 that most pre-Medicare retirees miss: Affordable Care Act marketplace health insurance subsidies are income-based. Premium tax credits phase out aggressively above 400% of the federal poverty level (~$77,000 for a couple in 2024). A couple who keeps their income under this threshold can receive significant ACA subsidies — potentially $800-1,500/month in health insurance assistance — that evaporate if they draw heavily from traditional accounts and push income too high.
This creates a reason to be conservative with traditional account withdrawals and Roth conversions before Medicare eligibility at 65. It also creates an additional argument for drawing primarily from taxable accounts in this window, since capital gains below certain thresholds don't eliminate ACA eligibility the way large ordinary income does.
The retirement income planning and tax withdrawal strategy guide covers the ACA-Medicare transition, the 0% capital gains window, and the Roth conversion timing in integrated detail — particularly valuable for anyone planning a retirement at 60-65 when healthcare costs and ACA eligibility significantly affect the income management decisions.
Practical Steps to Start Implementing This
Step 1: Inventory your accounts. List each account type (traditional, Roth, taxable), its current balance, and its approximate cost basis in the case of the taxable account.
Step 2: Project your Social Security benefit at different claiming ages using ssa.gov's estimator. The difference between claiming at 62 vs 70 is roughly 76% more monthly benefit at 70 — one of the highest guaranteed returns in personal finance.
Step 3: Calculate your annual income need and identify how many years you have before Social Security starts.
Step 4: Calculate your Roth conversion capacity — the amount you can convert each year and stay in the 12% bracket (or below your targeted bracket).
Step 5: Build a year-by-year withdrawal and conversion plan, or engage a fee-only financial planner to model the scenarios. The value of professional analysis for a household with $500,000+ in retirement accounts is consistently higher than the one-time planning fee.
The Retire Secure tax-advantaged withdrawal strategy book by James Lange specifically addresses the withdrawal order question for retirees with multiple account types, including the interaction between Social Security timing, Roth conversions, and RMD planning. For a more comprehensive overview of building a retirement income stream from multiple sources, the New Retirementality retirement planning framework addresses the psychological and practical dimensions of moving from accumulation to distribution mode — a transition that requires a different mental model, not just different math.

The bottom line: at 62 with multiple account types, the conventional 'taxable first' rule is the right starting framework, but it needs to be paired with active Roth conversion work during the low-income pre-Social Security window. The households that manage this phase deliberately — drawing from taxable, converting from traditional at low rates, and leaving the Roth untouched to compound — arrive at 73 with meaningfully smaller RMD obligations, more tax-free assets, and a lower lifetime tax bill on the same wealth. That's not a marginal difference. For most households with $500,000+ in retirement assets, the gap between optimized and unoptimized withdrawal sequencing is measured in the tens of thousands of dollars over a 20-30-year retirement.
