Quick Answer: The baseline withdrawal order moves from taxable brokerage accounts to pre-tax IRAs/401(k)s, finishing with tax-free Roth accounts. However, an optimal strategy dynamically coordinates all income sources (wages ending, Social Security, Medicare IRMAA thresholds, Roth conversions, and forced RMDs) to minimize lifetime taxes rather than draining accounts in a rigid line.
Key Takeaways
- Drawing down taxable brokerage accounts, pre-tax IRAs, and tax-free Roth accounts in the right strategic sequence lowers your lifetime tax drag.
- Aligning your 401(k) distributions with Social Security and Medicare thresholds prevents costly IRMAA surcharges, bracket creep, and future RMD tax bombs.
- The most tax-efficient retirement plan uses annual tax bracket filling to manufacture income up to low threshold limits rather than draining one account to zero before touching the next.
One of the worst assumptions you can make about your retirement income is that having enough is all that matters.
Accumulating savings is important⊠but how you withdraw those savings can cost you thousands.
If you pull from your retirement buckets in the wrong order, you can run into tax traps like subjecting your Social Security to federal tax or incurring costly Medicare premium surcharges.
So, let me walk you through how Iâve helped other Colorado Springs clients turn retirement income valves in the right sequence.
In what order do you withdraw retirement funds?
The standard tax-efficient sequence for withdrawing retirement funds is: 1) Taxable brokerage accounts and cash reserves first to capture lower long-term capital gains rates; 2) Tax-deferred accounts (Traditional IRAs and 401(k)s) up to the top of lower income tax brackets; and 3) Tax-free Roth accounts last to maximize tax-sheltered compounding. But in certain cases, strategic deviations like partial Roth conversions or filling specific tax brackets before claiming Social Security can help minimize your lifetime tax drag.
To build a tax-smart withdrawal sequence, we have to evaluate how all these moving parts interact on your tax return:
- Earned income and severance, like final wages, accrued PTO payouts, or deferred compensation that create a high baseline tax bracket during your initial transition year.
- Non-retirement taxable brokerage accounts subject to capital gains tax rates, plus the 3.8% Net Investment Income Tax (NIIT) threshold.
- Traditional IRAs & 401(k)s
- Social Security benefits. Up to 85% of your benefit becomes taxable once your “provisional income” (AGI + tax-exempt interest + 50% of your Social Security benefit) crosses federal thresholds.
- Medicare Parts B & D, and Income-Related Monthly Adjustment Amount (IRMAA) surcharges triggered by a two-year lookback on your Modified Adjusted Gross Income (MAGI).
- Roth conversions, which means transferring funds from pre-tax IRAs to tax-free Roth accounts during low-income gap years to shrink future pre-tax balances.
- Required Minimum Distributions (RMDs) starting at age 73 (or age 75 for those born in 1960 or later) that force taxable income onto your return.
- Qualified Charitable Distributions (QCDs), which are transfers from an IRA to a qualified charity (available starting at age 70œ) that count toward your RMD without adding anything to your taxable AGI.
So, rather than relying on a generic”taxable first, pre-tax second, Roth last” approach, structure your drawdown strategy by four phases:
Phase 1: The transition and gap years (retirement to age 65)
Your goal: Fill low ordinary income tax brackets while controlling AGI for ACA premium tax credits or low capital gains rates.
In this phase, weâll tap taxable cash or brokerage accounts to cover your living expenses, which helps keep your taxable income artificially low. Then weâll use your remaining headroom in lower tax brackets to execute Roth conversions before Medicare rules take effect.
Phase 2: The Medicare window (ages 65 to 69)
Your goal: Fund your lifestyle while avoiding Medicare IRMAA surcharge cliffs.
How do you accomplish that? By blending withdrawals between taxable brokerage accounts (harvesting long-term capital gains) and tax-free Roth accounts. Because IRMAA uses a two-year lookback, weâll need to carefully monitor your MAGI starting at age 63 so your age-65 Medicare premiums don’t spike.
Phase 3: Social Security integration and Pre-RMD reduction (ages 70 to 72/74)
Your goal: Maximize lifetime guaranteed income while defusing the upcoming “RMD tax bomb.”
Claim delayed Social Security benefits at age 70 to lock in maximum monthly growth. Perform final-stretch Roth conversions on traditional IRA balances to minimize the mandatory distribution floor youâll have to take in Phase 4.
Phase 4: The mandatory distribution and charitable giving era (age 73/75+)
Your goal: Satisfy mandatory federal tax obligations while preventing unnecessary bracket creep.
At this point, you should take mandatory RMDs from tax-deferred accounts first. If you give to charity, execute Qualified Charitable Distributions (QCDs) from your traditional IRA up to $111,000 per year to satisfy RMD requirements without raising your AGI. Cover any leftover spending needs using tax-free Roth withdrawals.
What is the best withdrawal strategy for retirement funds?
The best retirement withdrawal strategy uses dynamic bracket-filling rather than a rigid account sequence. By blending distributions from taxable, pre-tax, and tax-free accounts each year, you keep your Adjusted Gross Income (AGI) within low tax brackets, avoid Medicare IRMAA surcharges, and keep your overall lifetime tax drag low.
To see how drastically account sequencing impacts your net wealth, look at how everyday decisions play out when executed blindly versus strategically:
| Strategy Decision | Uncoordinated Order | Tax-Optimized Order | Tax Impact |
| IRA Distribution Timing | Taking sporadic, large IRA distributions only when cash is needed, spiking taxable income into the 24%+ marginal tax brackets. | Taking systematic annual pre-tax distributions up to the top of the 10% or 12%/22% brackets every year. | Prevents artificial tax bracket spikes and shrinks future RMDs. |
| Social Security & Pre-Tax Coordination | Claiming Social Security at age 62 while leaving IRAs untouched until mandatory RMD ages. | Delaying Social Security to age 70 while living on or converting pre-tax IRA assets during lower-income gap years. | Increases guaranteed lifetime benefit while reducing provisional income that subjects Social Security to federal tax. |
| Medicare Cliff Management | Ignoring the two-year MAGI lookback and taking a large IRA withdrawal that crosses a Medicare threshold by $1. | Monitoring MAGI to take extra cash from Roth or taxable brokerage accounts before hitting an IRMAA tier. | Saves $1,000 to over $6,000 annually per couple in avoided Medicare Part B and D surcharges. |
| Charitable Giving Execution | Writing personal checks to charities from cash while taking taxable IRA RMDs separately. | Executing QCDs directly from an IRA to qualified charities (up to $111,000 per individual). | Satisfies RMDs dollar-for-dollar while keeping that income off your AGI entirely. |
For a dynamic withdrawal approach, I always recommend three best practices to my Colorado Springs clients:
- Practice active tax bracket filling. If youâre in the 12% tax bracket and have $25,000 of headroom before hitting the 22% bracket, donât let that cheap tax capacity go to waste. Fill that gap with traditional IRA distributions or Roth conversions, even if you donât need the extra cash for living expenses.
- Manage AGI thresholds first, cash second. Cash flow is what you spend; AGI is what the IRS taxes. Use tax-free Roth accounts or taxable brokerage principal to fund big-ticket purchases (like a new vehicle or home renovation) so your taxable income stays flat.
- Treat accounts as a single portfolio. Your traditional IRA, Roth IRA, and taxable brokerage account are designed to work together so you pay the minimum tax allowable by law across your entire retirement.
How can you minimize taxes when taking money out of retirement accounts?
Alright, weâve gone over when to pull and how much bracket room to use. Now, how do you make your withdrawals in the most tax-efficient way? Some strategies we can consider are harvesting long-term capital gains in the 0% tax bracket, deploying Net Unrealized Appreciation (NUA) for company stock, utilizing Qualified Longevity Annuity Contracts (QLACs) to defer RMDs, and drawing tax-free medical reimbursements from an HSA.
Hereâs a closer look at five tactical maneuvers I use with North Colorado Springs clients to lower the tax hit on retirement distributions:
1. Execute tax-gain harvesting in the 0% capital gains window.
If your total taxable income (ordinary income plus realized capital gains) is below $98,900 for married joint filers (or $49,450 for single filers), your long-term capital gains tax rate is 0%. During early retirement gap years, you can sell appreciated assets from your taxable brokerage account, pay $0 in federal tax on those gains, and immediately repurchase the assets to permanently step up your cost basis.
2. Elect Net Unrealized Appreciation (NUA) for company stock.
If you hold highly appreciated company stock inside an employer-sponsored 401(k), donât automatically roll it over into a Traditional IRA. Under NUA rules, you can distribute the stock into a taxable brokerage account upon separation from service.
You pay ordinary income tax only on the original cost basis, while the appreciation is taxed at lower long-term capital gains rates when sold, which bypasses ordinary income rates.
3. Carve out RMDs using a QLAC.
If your Required Minimum Distributions could push you into a higher tax bracket or trigger Medicare IRMAA surcharges, you can transfer up to $210,000 from your pre-tax IRA or 401(k) into a Qualified Longevity Annuity Contract (QLAC). That $210,000 is removed from your RMD calculation balance, so your required distributions on those funds are deferred until age 85.
4. Tap HSA “reimbursement banking” for tax-free cash.
If you paid out-of-pocket for qualified medical expenses years ago and saved the receipts, you can reimburse yourself from your HSA tax-free at any point during retirement. This creates a source of tax-free cash flow that doesnât count toward your AGI, provisional income, or IRMAA thresholds.
5. Leverage state-specific retirement exclusions.
Many states offer exclusions for pension income, social security, or specific pre-tax retirement withdrawals once you cross ages 62 or 65. Structuring your distributions around state-level tax thresholds prevents unnecessary state income tax drag.
Final thoughts
Iâve offered you my best advice on what order to withdraw retirement funds, but actually executing that sequencing with your exact accounts and tax brackets is a totally different matter.
To do this well, weâll need to analyze your specific income sources and map out a customized, multi-year drawdown plan that keeps your lifetime tax bill as low as possible. Just book a time on my calendar, and we can get started:
FAQs
âWhich retirement funds should I withdraw first?â
The standard is to withdraw from taxable brokerage accounts first, pre-tax accounts (Traditional IRAs and 401(k)s) second up to lower tax bracket limits, and tax-free Roth accounts last. This keeps your tax-free Roth assets compounding for as long as possible while keeping your immediate taxable income low. However, my preferred approach is to blend withdrawals across all three buckets depending on your spending needs each year so you never waste room in lower tax brackets.
âWhat is the smartest way to withdraw a 401(k)?â
The smartest way to withdraw from a traditional 401(k) is through systematic, scheduled distributions that fill lower ordinary income tax brackets without triggering Medicare IRMAA surcharges or pushing you into higher capital gains tiers. Lump-sum withdrawals are rarely the answer because they artificially spike your marginal tax bracket.
âHow much tax will I pay on my 401(k) withdrawal?â
Traditional 401(k) distributions are taxed as ordinary income at your current federal marginal rate (10% to 37%) plus applicable state income taxes. Your exact tax rate depends on your total combined taxable income for the calendar year, which includes pension income, wages, and taxable Social Security benefits. If you make a pre-tax withdrawal before age 59Âœ, youâll also owe a 10% federal early withdrawal penalty (unless you meet a specific IRS exception).
âHow should I sequence withdrawals from my 401(k), IRA, and Roth accounts?â
Sequence your distributions by using taxable accounts for base living expenses, topping off lower tax brackets with pre-tax 401(k) and IRA distributions, and saving Roth accounts for tax-free tax bracket protection or legacy goals. During low-income gap years between your retirement date and claiming Social Security, accelerating pre-tax IRA and 401(k) withdrawals or executing partial Roth conversions can permanently reduce the size of your future Required Minimum Distributions.
âWhich retirement accounts should I tap into first for steady income?â
Tap fixed income streams and taxable cash reserves first, supplemented by planned, fixed-amount distributions from your pre-tax traditional IRA or 401(k). Starting with taxable cash or interest gives you control over your baseline Adjusted Gross Income (AGI). Then, layer in pre-tax distributions up to your target tax bracket ceiling, keeping tax-free Roth accounts in reserve as a flexible buffer for unexpected major purchases.
âWhat are best practices for drawing down a 401(k) and IRA in retirement?â
Top best practices include running multi-year tax projections, managing the two-year Medicare IRMAA lookback window, executing proactive Roth conversions before RMD age, and utilizing Qualified Charitable Distributions (QCDs) starting at age 70œ. Managing your pre-tax accounts around mandatory distribution ages (age 73 or 75) ensures you prevent unexpected tax spikes and keep more of your wealth working for you throughout retirement.
