Most retirement guides hand out the same tidy answer without much nuance: spend your taxable brokerage account first, then your Traditional IRA and 401(k), and save the Roth for last. It’s repeated so often it sounds like settled fact. It isn’t. The most tax-efficient withdrawal order can vary from one retiree to another. Account types, Social Security, required minimum distributions, Medicare premiums, investment gains and future tax considerations can all affect which account makes sense to use in a particular year. It’s a genuinely different retirement outcome hiding inside a decision most people never think to question.
Understanding Each Account’s Tax DNA
Before sequencing withdrawals intelligently, it helps to understand that each account type carries a distinct tax personality, one that shapes not just how it’s taxed today, but how withdrawing from it interacts with everything else happening on that year’s tax return.
Taxable Brokerage Accounts
Money in a standard brokerage account has already been taxed once, as income, before it was invested. Selling investments inside this account triggers capital gains tax, and for 2026, long-term capital gains and qualified dividends are actually taxed at a 0% federal rate as long as total taxable income stays under $98,900 for married couples filing jointly or $49,450 for single filers, according to this 2026 withdrawal sequencing guide. That 0% bracket is a genuinely valuable planning tool, but it only works cleanly if other income, including any IRA withdrawal, isn’t stacking on top of it and pushing gains out of that zero-rate zone.
Traditional IRAs and 401(k)s
The taxable portion of distributions from Traditional IRAs and 401(k)s is generally included in ordinary income for federal tax purposes. These accounts also carry a hard deadline attached to them: required minimum distributions currently begin at age 73, forcing withdrawals whether the retiree needs the income or not, according to this 2026 tax-efficient withdrawal order guide.
Roth IRAs and Roth 401(k)s
Qualified withdrawals from a Roth account are entirely free of federal income tax, including all the investment growth that accumulated over decades. Because Roth IRAs carry no RMD requirement during the original owner’s lifetime, they also offer something the other two account types don’t: genuine flexibility about exactly when, or whether, to withdraw at all.

Why the “Obvious” Order Often Backfires
The conventional taxable-then-traditional-then-Roth sequence exists for a defensible reason: it defers taxation as long as possible and preserves Roth growth for heirs. The problem is what happens by the time Traditional withdrawals finally get forced into the picture.
The Tax Torpedo Hiding at the End of the Conventional Sequence
Following the conventional order tends to concentrate large Traditional account withdrawals into the later retirement years, exactly when required minimum distributions and Social Security income are both landing in the same tax return simultaneously, according to this 2026 retirement withdrawal order analysis. This collision, sometimes called a tax torpedo, can push a retiree into a meaningfully higher bracket than they occupied throughout the earlier, quieter years of retirement, and it can also trigger something many retirees don’t see coming at all: higher Medicare premiums.
How Medicare Premiums Get Pulled Into the Decision
Because IRMAA uses income thresholds, crossing a threshold can move a Medicare beneficiary into a higher premium tier. This makes large Traditional-account withdrawals and Roth conversions important to evaluate alongside Medicare costs. A Roth conversion or a large Traditional withdrawal that looks perfectly reasonable on an income tax return alone can turn out to be a costly mistake once this Medicare surcharge is factored into the full picture.
A Smarter Approach: Filling Brackets Instead of Following Rules
Rather than mechanically draining one account type before touching the next, a more effective strategy treats each year’s tax bracket as a container to be filled deliberately, using whichever account best fits the space available that particular year.
What Dynamic, Bracket-Based Sequencing Looks Like in Practice
A handful of principles guide this more flexible, year-by-year approach:
- During years with genuinely low other income, particularly before Social Security or an RMD begins, drawing from Traditional accounts to fill up the lower tax brackets, or executing a Roth conversion, uses otherwise wasted low-bracket space
- During years when other income is already high, drawing from Roth or taxable accounts avoids stacking additional ordinary income on top of an already elevated bracket
- Coordinating capital gains from taxable investments with Traditional-account withdrawals can help manage the overall tax impact of income recognized during the same year.
Why This Gets More Complicated for Puerto Rico Residents
A Puerto Rico resident’s withdrawal sequencing decision layers Puerto Rico’s own tax treatment on top of everything already described here, and the interaction between the two systems doesn’t always follow intuition. A traditional IRA in Puerto Rico or a Roth IRA in Puerto Rico established locally may carry different rules than a mainland account of the same name, and coordinating withdrawal timing across both federal and Puerto Rico tax obligations requires understanding both systems simultaneously rather than optimizing for one while ignoring the other entirely.
Puerto Rico-Specific Factors Worth Layering Into the Sequence
A handful of island-specific considerations deserve a place in this planning conversation alongside the general federal principles already covered:
- Whether a given retirement account is Puerto Rico-qualified only, dual-qualified, or a mainland-only account changes both the withdrawal rules and the tax treatment on both sides
- Puerto Rico’s own tax brackets and rates don’t mirror the federal brackets exactly, meaning a withdrawal that fills a low federal bracket efficiently might land differently against Hacienda’s schedule
- TSP distributions, federal pensions, Puerto Rico-qualified plans and other retirement accounts may be subject to different sourcing and tax rules, so each income source should be evaluated separately
What Heirs Change About the Calculation
The optimal sequence isn’t purely about the retiree’s own lifetime tax bill; it also depends on what happens to remaining assets after death, and this consideration can meaningfully shift the ideal strategy. Certain inherited assets may receive an adjusted federal income-tax basis at death, subject to applicable rules. For a retiree expecting to leave assets to heirs in a higher tax bracket than their own, deliberately drawing down Traditional accounts more aggressively during their own lifetime, even at a modest present-day tax cost, may affect the after-tax amount ultimately received by beneficiaries. Many non-spouse beneficiaries of inherited retirement accounts may be subject to a 10-year distribution period under federal rules, although exceptions and additional distribution requirements can apply.
A Worked Example Showing the Sequences Side by Side
Numbers make this concrete in a way abstract principles alone don’t. Consider a single retiree, age 66, already on Medicare, who wants $85,000 in total annual cash flow, receives $35,000 from Social Security, and needs to draw the remaining $50,000 from a portfolio split across taxable, Traditional, and Roth accounts.
Comparing Single-Account, Proportional, and Dynamic Approaches
Three genuinely different sequencing philosophies would handle that same $50,000 need very differently, according to this 2026 coordinated withdrawal strategy analysis:
- A single-account approach draws the entire $50,000 from one account type exclusively until it’s exhausted, which is simple to execute but ignores the tax-bracket-filling opportunities available in any given year
- A proportional approach draws a fixed percentage from each account type every year regardless of the current tax situation, smoothing withdrawals but still missing the chance to exploit unusually low-income years
- A dynamic approach adjusts the specific mix each year based on that year’s other income, drawing more from Traditional accounts during genuinely low-income years and shifting toward Roth or taxable withdrawals when other income is already elevated
A dynamic approach may improve tax flexibility because the withdrawal mix can be adjusted as income, tax rules, markets and personal circumstances change. A year with unusually low medical expenses, a year before Social Security begins, or a year with a one-time deduction all represent genuine opportunities a rigid, mechanical sequence simply can’t capture.
The First Decade Carries Outsized Importance
Beyond the tax mechanics already covered, timing carries another dimension worth understanding on its own: sequence of returns risk. Withdrawals taken during the first several years of retirement, particularly if markets decline during that window, permanently reduce the base a portfolio has left to compound from, since money withdrawn during a downturn never gets the chance to participate in the eventual recovery. This risk exists entirely separately from the tax-bracket considerations already discussed, but it interacts with them directly, since a retiree forced to sell depressed taxable assets early in retirement, purely to avoid a Traditional withdrawal that would trigger a tax torpedo, may be trading a tax problem for an investment problem.
Balancing Tax Efficiency Against Sequence of Returns Risk
A genuinely well-built withdrawal plan holds both risks in mind simultaneously rather than optimizing for one while ignoring the other:
- Maintaining an appropriate liquidity reserve may reduce the need to sell investments during a market downturn. The appropriate amount depends on spending needs, income sources, risk tolerance and other circumstances.
- Reviewing the withdrawal plan annually, rather than setting it once and leaving it alone, allows real-time adjustment as markets and personal circumstances actually unfold
- Recognizing that the mathematically optimal tax sequence in a given year may need to bend slightly to avoid selling depressed assets, accepting a small tax inefficiency in exchange for protecting the portfolio’s long-term recovery potential

Building a Sequence Instead of Following a Rule
There is no single universally correct withdrawal order, and the specific sequence that minimizes lifetime taxes depends on account balances, expected future income, health and longevity expectations, and what a retiree actually wants their remaining assets to accomplish. A retirement planning services in Puerto Rico relationship that models these variables against a retiree’s actual numbers, year by year rather than as a single static rule, is what actually can help retirees evaluate the tax and income consequences of different withdrawal strategies rather than relying on a single predetermined order.
