Most retirement content answers the question of how much you can safely spend. Far less of it answers the question that arrives the same morning: the money has to come from somewhere, and you own three or four accounts that are taxed in completely different ways. Pulling 70,000 dollars out of a traditional IRA and pulling the same 70,000 out of a Roth account produce identical spending and wildly different tax bills. That difference, repeated across a thirty year retirement, is one of the larger controllable levers a household has.
This walkthrough covers the order in which retirement accounts are usually spent, the reasoning behind the conventional sequence, and the situations that justify departing from it. It also covers the two forces that take the choice out of your hands or hand it back: required distributions, which force pre-tax money out on a schedule, and the low-income years before those requirements start, when filling a lower band deliberately can be worth more than following the default. Every rate, band, balance, and dollar figure in this walkthrough is illustrative, chosen to make the arithmetic visible. Tax rates, thresholds, and starting ages are set by law and change, so confirm the current figures with the IRS or a qualified tax professional. Run your own balances in the companion on this page, and model longer horizons in our savings calculator.
Key takeaways
- The conventional sequence is taxable first, tax-deferred second, Roth last, and the logic is that it pays the smallest tax bill now while leaving the most sheltered money compounding longest.
- The sequence is a default, not a rule. Low-income years, large one-off expenses, and income-linked thresholds all justify blending across buckets instead of emptying one at a time.
- Required minimum distributions remove the discretion from the pre-tax bucket, which is why the years before they begin carry most of the planning value.
- Bracket filling means using cheap low-rate room before it expires at the end of the year, either by withdrawing extra from a pre-tax account or converting an equivalent amount.
- Only the gain portion of a taxable sale is taxed, so a taxable account with a high cost basis is usually the cheapest source of cash in any given year.
Why withdrawal order is a decision of its own
Two households can hold identical balances, spend identical amounts, and finish retirement with visibly different net worth purely because of where each dollar came from. That is worth sitting with, because it is not intuitive. Spending is spending. The account it left does not change what you bought.
What it changes is the tax attached to the transaction and the compounding that continues afterwards. A dollar taken from a pre-tax account arrives with income tax due on the whole amount. A dollar taken from a taxable brokerage account arrives with tax due only on the growth. A dollar taken from a qualified Roth withdrawal arrives with no tax at all. Meanwhile every dollar you did not touch stays invested, and the shelter quality of the account it sits in determines how much of its future growth you keep.
So withdrawal order is really two questions wearing one coat. Which source is cheapest to spend from this year, and which source is most valuable to leave alone for the next twenty. The conventional answer happens to satisfy both at once for most households, which is why it became conventional. It stops satisfying both when your income in a particular year is unusually low or unusually high, and that is where the exceptions live.
The three tax buckets your retirement money sits in
Almost every account a retiree holds falls into one of three tax categories, and the category matters far more than the product name on the statement.
The taxable bucket is a regular brokerage or bank account. You funded it with money that had already been taxed, and you pay tax each year on dividends and interest and on any gains you realize by selling. Nothing is sheltered, but nothing is locked either, and only the growth is taxed on the way out.
The tax-deferred bucket holds traditional 401(k), traditional IRA, 403(b), SEP and similar money. You got a deduction going in, nothing was taxed while it grew, and the entire withdrawal is ordinary income when it comes out. The tax was postponed, not cancelled.
The tax-free bucket holds Roth IRA and Roth workplace money. You paid tax on the way in, and qualified withdrawals come out untaxed, growth included. Our breakdown of the types of retirement accounts sets out how the account types differ in other respects, and our comparison of taxable and retirement accounts covers the choice on the way in rather than the way out.
The conventional sequence, stated plainly
The default that most planners describe runs taxable, then tax-deferred, then Roth. Spend the brokerage account and cash first. When that is exhausted, or nearly so, move to the traditional accounts. Leave the Roth accounts for last, ideally for very late in retirement or for heirs.
Two separate principles produce that ordering. The first is to pay the lowest tax you can on this year’s spending, and taxable withdrawals usually clear that test because only the gain is taxed. The second is to preserve shelter, and the Roth bucket has the best shelter, so it should be the last thing you break into.
The sequence is a rule of thumb built for the average case, and the average case is a household whose income is fairly steady and whose balances are spread across all three buckets. The further your situation sits from that description, the less the default suits you. A retiree with almost everything in a traditional 401(k) and nothing taxable does not have much of a sequence to run. Someone retiring at 55 with a large brokerage account and a long wait before any pension or benefit starts has a very different set of options, which the section on early retirement returns to.
Why taxable accounts usually go first
The strongest argument for spending taxable money first is that you are only taxed on part of it. Suppose you sell 40,000 dollars of a fund position and, on an illustrative basis, two thirds of that sale represents money you originally invested and one third represents growth. Only the growth, about 13,200 dollars, is exposed to tax. At an illustrative 15 percent long-term rate, the bill is roughly 1,980 dollars, which is under 5 percent of the cash you raised.
Compare that with the same 40,000 dollars taken from a traditional IRA. Every dollar is ordinary income. At an illustrative 22 percent marginal rate, that is 8,800 dollars of tax, more than four times as much for identical spending power.
The second argument is about what you leave behind. A taxable account is taxed every year on its dividends and realized gains whether you spend from it or not. That annual drag never stops. Money in a traditional or Roth account has no such drag. So spending down the account with the ongoing leak, while leaving the sealed ones alone, converts a small recurring tax cost into no cost at all. That is the quiet compounding benefit the default sequence is really chasing.
Why traditional accounts usually go second
Once taxable money is spent, the pre-tax accounts are next in the default sequence, and the reason is mostly a process of elimination: they are more expensive to draw than taxable money and less valuable to preserve than Roth money.
There is a second, more forward-looking reason. Pre-tax balances do not stay optional forever. Required distributions eventually force money out of them, and the larger the balance is when that starts, the larger the forced withdrawal. Drawing from pre-tax accounts during retirement, rather than leaving them untouched, shrinks the balance that future required amounts will be calculated from. Our explainer on required minimum distributions covers how that calculation actually works, and our walkthrough of 401(k) withdrawal rules covers the age and penalty mechanics on the plan side.
There is a real tension inside this step. Every dollar you take from a pre-tax account is taxed at your ordinary rate today, and the whole point of deferral was to be taxed later at a hopefully lower rate. Taking too much too early wastes the deferral. Taking too little leaves a large balance to be forced out later, possibly at a higher rate. The resolution is not a fixed percentage but an annual judgement about where this year’s rate sits relative to your expected future one.
Why Roth money usually goes last
A Roth account is the best-treated dollar you own, and the default sequence protects it for as long as possible for exactly that reason. Qualified withdrawals are untaxed. Growth inside the account is untaxed. And a Roth IRA has generally not required its original owner to take distributions during their lifetime, which means it can compound untouched for as long as you live.
Put those together and the Roth bucket has a longer productive life than either of the others. Every year you avoid touching it is a year of untaxed growth you keep. That is why planners talk about Roth money as the last resort and, often, as the best thing to leave to heirs.
Our walkthrough of Roth IRA withdrawal rules covers the ordering rules that apply inside the account itself, including how contributions and earnings are treated on the way out and how multiple IRAs interact, and it is worth reading alongside this one rather than having its rules restated here. The practical point for sequencing is that the Roth bucket is your flexibility reserve. When a large expense or a threshold problem appears, Roth money is the source that can absorb it without adding a cent to taxable income.
Illustrative after tax value of a thousand dollars by source
The clearest way to see why the sequence exists is to price a single withdrawal from each source. The chart below takes 1,000 dollars of cash raised and shows what is left after illustrative tax. Every rate is invented for teaching.
What 1,000 dollars of cash raised is worth after illustrative tax
Assumes a taxable sale that is one third gain at an illustrative 15 percent rate. All rates are illustrative, not current published values.
The gap between a taxable sale and a pre-tax withdrawal at an illustrative 22 percent rate is about 171 dollars per thousand raised. On 40,000 dollars of annual spending that is roughly 6,800 dollars of difference in a single year.
Notice that the taxable bar sits close to the Roth bar rather than close to the pre-tax ones. That is the whole case for the default sequence in one picture. Notice also that the pre-tax bars move a lot with the rate, which is the case for the exceptions: a pre-tax withdrawal at a low illustrative rate is cheaper than most people assume. Change the basis share and the rate in the companion on this page to build your own version of this chart.
Cost basis is what makes taxable withdrawals cheap
The taxable bar in that chart is high for one reason only: cost basis. Basis is the money you originally put in, and it comes back to you untaxed when you sell. Only the growth above basis is taxable.
That means the cheapness of a taxable withdrawal is not a fixed property of the account. It depends entirely on how much unrealized gain the position carries. A fund you bought last year and that has barely moved is almost all basis, so selling it is nearly tax-free. A position you have held for twenty years may be mostly gain, and selling it could realize more taxable income than a pre-tax withdrawal of the same size would.
Two practical consequences follow. First, when you need cash from a taxable account, look at the individual lots rather than the account total, because different purchases carry different bases and most brokerages will let you choose which lots to sell. Second, a taxable account is not automatically the cheapest source. Run the actual gain fraction. If your account is 90 percent gain, a sale may cost more than the default sequence assumes, and the exercise of comparing it against a pre-tax withdrawal in a low band is worth doing rather than skipping.
Required minimum distributions take the choice away
Everything above assumes you get to choose. At some point you stop choosing, at least for part of the money. Required minimum distributions oblige you to withdraw a minimum amount from traditional accounts each year once you reach the applicable starting age, and that amount comes out whether your sequencing plan wanted it to or not.
The mechanics are covered in our explainer on required minimum distributions, so the point here is only the sequencing consequence. Once the requirement begins, the pre-tax bucket is no longer at the back of a queue you control. A required withdrawal is the first call on your income, and everything else in the plan has to work around it.
That reframes the pre-requirement years completely. They are the only years in which the pre-tax balance can be reduced on your terms and at a rate you chose. A household that spends only taxable money through its sixties, feeling efficient, can arrive at the requirement with a very large pre-tax balance and find the forced withdrawal lands on top of Social Security and pushes the whole household into a higher band. On an illustrative 600,000 dollar pre-tax balance and an illustrative life expectancy factor of 24, the required amount would be about 25,000 dollars a year, arriving whether or not the household needs it.
One further sequencing rule matters. In a year when a distribution is required, the first money out of the account counts toward that requirement and is not eligible for conversion. Satisfy the requirement first, then do anything else.
How bracket filling breaks the sequence
Bracket filling is the most important exception to the default order, and it is the reason a strict taxable-first plan can quietly cost money.
Marginal tax bands are annual. Room in a lower band that you do not use before the year ends is gone; it does not roll forward. So if your taxable income in a given year falls well short of the top of a lower band, you are leaving cheap space on the table. Filling it means voluntarily taking more from a pre-tax account than you need, or converting an equivalent amount to Roth, so those dollars are taxed now at the lower rate instead of later at a higher one.
Consider the shape of the argument on the illustrative numbers from the chart above. A pre-tax dollar taken at an illustrative 12 percent leaves about 880 dollars per thousand. The same dollar taken later at an illustrative 24 percent leaves about 760. That 120 dollar per thousand difference is the prize, and it is only available in years when your income is genuinely low.
Two cautions. The bands themselves are set annually and change, so the amount of room you actually have has to be looked up for the current year rather than estimated from memory. And filling a band is not free of side effects, because the extra income can interact with benefit taxation and premium surcharges covered further down. Model it or take advice before acting.
The bridge years before Social Security starts
The single best window for departing from the default sequence is usually the stretch between the day work income stops and the day a Social Security benefit or pension starts. Wages have ended. Benefits have not begun. Required distributions have not begun either. Taxable income in those years can be remarkably low.
That low-income window is exactly when pre-tax withdrawals and Roth conversions are cheapest, and it is also finite. It closes the moment a benefit claim starts, and it closes for good when required distributions begin. A household that delays claiming in order to raise the eventual monthly benefit is, as a side effect, buying itself a longer cheap window, which is one of the underappreciated arguments for delaying.
Our explainer on the full retirement age and our walkthrough on estimating a benefit cover the claiming side of that decision. For sequencing purposes, the useful discipline is to treat the bridge years as a budget of cheap tax room that expires, and to decide each autumn how much of it to use.
How Roth conversions ride along with the order
A conversion is not a withdrawal, but it belongs in the same conversation because it uses the same resource: room in a low band. Converting moves money from a traditional account to a Roth account and taxes the converted amount as ordinary income in the year you do it.
The relationship to sequencing is direct. If you have decided to fill a lower band this year, you can do it by withdrawing pre-tax money and spending it, or by converting pre-tax money and keeping it invested in a Roth account. The tax cost is the same. The difference is whether the dollars end up in your current account or in the best-sheltered bucket you own.
If you have cash available from taxable savings to pay the tax, converting is usually the stronger use of the room, because the full converted amount lands in the Roth account and every future dollar of growth on it is sheltered. Our walkthrough on doing a Roth conversion covers the mechanics and the timing, and our comparison of Roth and traditional IRAs covers the underlying trade. Conversions are irreversible in the sense that the tax is due for that year, so the arithmetic is worth doing carefully rather than in December.
Social Security taxation behaves like a hidden bracket
Here is the effect that catches careful planners out. The share of a Social Security benefit that counts as taxable income is not fixed. It rises as your other income rises, according to a formula set in statute.
The sequencing consequence is that a pre-tax withdrawal can be more expensive than its headline rate suggests. If an extra 1,000 dollars of pre-tax withdrawal also causes additional benefit dollars to become taxable, you are taxed on more than the 1,000 you took. The effective rate on that withdrawal can be noticeably higher than the band you thought you were in, and there is a well-documented range of income over which this compounding effect is at its worst.
Two things follow. First, this is a strong argument for doing pre-tax withdrawals and conversions before a benefit claim starts rather than after, when no benefit exists to be dragged into the tax base. Second, once benefits are flowing, Roth withdrawals become more attractive at the margin than the default sequence suggests, because they add nothing to the income figure the formula looks at. The income thresholds in that formula are set by statute and have not historically been indexed the way other figures are, so look them up rather than assuming.
Medicare surcharges and the cliff problem
A second income-linked effect works differently and deserves separate attention. Medicare premiums carry income-related surcharges for higher-income households, and the surcharge structure works as a series of steps rather than a smooth slope.
That step structure is what makes it dangerous for sequencing. Crossing a threshold by a single dollar can raise premiums for a full year by a meaningful amount, which means the effective marginal cost of the dollar that crossed the line is enormous. There is also a lag between the income year and the premium year, so a large conversion or withdrawal today can affect premiums a couple of years later, long after you stopped thinking about it.
The practical response is to know where the next step sits before you take a discretionary withdrawal late in the year, and to use Roth money for anything that would otherwise push you over. Our walkthrough of healthcare costs in retirement covers the wider premium picture. The thresholds and surcharge amounts are set annually and move, so confirm the current figures rather than working from a table you saved.
Where an HSA belongs in the sequence
A health savings account sits outside the three-bucket framework, and where it belongs in a spending order depends on what you spend it on.
Used for qualified medical expenses, an HSA is the only account that is untaxed going in, untaxed while it grows, and untaxed coming out. Nothing else in the system offers all three. That combination argues strongly for keeping it near the very back of the queue and reserving it for medical costs, which retirement reliably produces.
Used for anything else after the applicable age, the withdrawal is generally taxed as ordinary income, which puts it on roughly the same footing as a traditional account rather than a Roth one. Our explainer on health savings accounts covers the eligibility and expense rules. For sequencing, the reasonable default is to treat the HSA as a dedicated medical reserve rather than as general spending money, and to let it compound as long as the rules allow.
The proportional alternative to strict sequencing
Strict sequencing has a structural weakness. Emptying one bucket at a time produces a lumpy income profile: very low taxable income while the brokerage account lasts, then a jump when the pre-tax withdrawals start, then whatever required distributions impose. Lumpy income wastes low-rate room in the early years and overshoots into higher bands later.
The alternative that planners increasingly describe is a proportional or blended draw. Instead of exhausting the taxable account first, you take a set share of each year’s spending from each bucket, aiming for a steadier taxable income across the whole retirement rather than a low period followed by a high one.
The blended approach is harder to run because it needs an annual calculation rather than a rule, and it gives up some of the shelter benefit of leaving sheltered accounts untouched. What it buys is smoother marginal rates and fewer threshold accidents. In practice most careful plans end up somewhere between the two: broadly taxable-first, with a deliberate slice of pre-tax withdrawal or conversion layered on top in the low years. That hybrid is what the worked example below actually does.
Where an illustrative bridge year gets its cash
To make the hybrid concrete, the chart below splits one illustrative year of spending in the bridge period, before any benefit claim and before any required distribution. The household needs 70,000 dollars of cash. Every figure is invented for teaching.
Sourcing an illustrative 70,000 dollar bridge year
Taxable-first with a deliberate low-band pre-tax slice layered on. Shares sum to 100.
The pre-tax slice here is not needed for spending. It is taken because the low band would otherwise go unused, and the Roth slice exists so the household can reach 70,000 dollars without pushing income any higher.
Two readings follow. First, no bucket is emptied and no bucket is untouched, which is what a hybrid looks like in practice. Second, the pre-tax slice is a choice rather than a necessity, and it is the piece that would disappear entirely in a year when income was already high. Change the spending figure and the balances in the companion on this page to see your own mix.
A worked example of a first decumulation year
Consider an illustrative household, which we will call the Okonjo household, in its first full year without wages. The balances are invented: 300,000 dollars in a taxable brokerage account with roughly two thirds of it representing original cost, 600,000 dollars across traditional accounts, and 200,000 dollars in a Roth IRA. Total investable balance 1,100,000 dollars. They need 70,000 dollars of cash for the year and no benefit has started.
They source it the way the chart above describes. They sell 40,000 dollars of taxable holdings. Because about one third of that sale is gain, roughly 13,200 dollars is taxable, and at an illustrative 15 percent rate the bill is about 1,980 dollars. They use 9,000 dollars of cash, dividends and interest already sitting in the account, which carries no further tax because it was taxed as it arrived. They take a deliberate 15,000 dollar withdrawal from a traditional IRA to use low-band room, and at an illustrative 12 percent rate that costs 1,800 dollars. They top up with 6,000 dollars from the Roth IRA, which adds nothing to taxable income.
Total tax for the year, on these illustrative rates, is about 3,780 dollars. Against 70,000 dollars of cash raised, that is an effective rate of roughly 5.4 percent, leaving about 66,220 dollars after tax. The taxable account has fallen to 260,000 dollars, the traditional balance to 585,000 before growth, and the Roth to 194,000.
Every rate and balance in this example is illustrative and none of it is a recommendation. Put your own figures into the companion on this page to see your version.
The same year sourced three different ways
The example above is only interesting next to the alternatives, so here is the same 70,000 dollar year funded three ways on the same illustrative rates.
Taking the entire 70,000 from traditional accounts, at an illustrative flat 22 percent marginal rate, would produce about 15,400 dollars of tax and leave about 54,600 dollars. That figure overstates the real bill, because marginal bands are graduated and the first slice of income would be taxed at lower rates, but it shows the direction and the scale clearly.
Taking the entire 70,000 from the Roth IRA would produce no tax at all and leave the full 70,000. It would also cut the Roth balance from 200,000 to 130,000 in one year, spending the most valuable dollars in the household on ordinary living costs and giving up their untaxed growth forever.
The blended approach sits between them at about 3,780 dollars of tax, which is roughly 11,620 dollars less than the all-pre-tax version, while leaving the Roth almost intact. That gap is the value of sequencing in a single year on invented numbers. Repeated annually it compounds, and it is why the question of which account to tap first is worth more attention than it usually gets. Model the long-run effect in our savings calculator and read our walkthrough on how long retirement savings will last for the other half of the picture.
Retiring before the early withdrawal age changes the order
If you stop working well before the age at which retirement accounts can generally be tapped without an additional penalty, the sequence is not a preference. It is a constraint.
In that situation the taxable account is not merely the cheapest source, it is often the only accessible one, which is why early retirement planning puts so much weight on building taxable savings alongside sheltered ones. There are recognized routes into retirement accounts before the usual age, including substantially equal periodic payments, certain separation-from-service provisions in employer plans, and the treatment of Roth contributions themselves, but each carries conditions that are easy to breach and consequences if you do.
Our walkthrough of 401(k) withdrawal rules covers the plan-side mechanics and our walkthrough of Roth IRA withdrawal rules covers the contribution ordering that early retirees rely on. The ages, exceptions and penalty rates involved are set by law and have been amended more than once, so verify the current rules for your specific plan before building an early retirement around any of them, ideally with a professional.
Sequence of returns risk and the cash buffer
There is a non-tax reason to think about where money comes from, and in a bad market it matters more than the tax reason.
Selling investments to fund spending during a market fall locks in losses and removes shares that would otherwise have participated in a recovery. Two retirees with identical average returns can end up in very different places purely because of the order in which good and bad years arrived, which is the effect usually called sequence of returns risk.
The common defence is a cash buffer, meaning one to three years of spending held in cash or short-term instruments so that a downturn does not force sales at the bottom. In sequencing terms the buffer sits ahead of everything else in the queue during bad years, and is refilled from investments during good ones. Our walkthrough on emergency fund sizing covers the same principle before retirement, and the retirement version is simply larger and more deliberate. The trade-off is real: cash held for safety is cash not compounding, so the buffer is insurance with a visible premium.
What your heirs inherit depends on the order too
Sequencing does not stop mattering at the end of your life, because the three buckets pass to heirs on very different terms.
Roth money has historically been the best thing to inherit, arriving untaxed to the beneficiary, though beneficiary accounts follow their own distribution timetable. Traditional money arrives with the deferred income tax still attached, and the beneficiary pays it at their own rate, which for a working adult child may be higher than yours. Taxable holdings have historically received a basis adjustment on death, which can eliminate the tax on a lifetime of unrealized gain.
Those three facts pull sequencing in a specific direction late in life: spend pre-tax money, preserve Roth money, and think hard before selling deeply appreciated taxable positions that could pass with an adjusted basis. Our explainer on retirement account beneficiary rules covers the beneficiary side properly. The rules governing inherited accounts have been rewritten by legislation in recent years and the basis adjustment is a recurring subject of policy debate, so treat this whole paragraph as a set of factors to check rather than a settled plan, and involve an estate professional.
Reviewing the order once a year
None of this survives being set once and left. Balances move, tax bands change, income varies, and the rules themselves get amended. The practical implementation is an annual review rather than a permanent policy.
The useful timing is autumn. By then you can see most of the year’s actual income, which is what determines how much low-band room is left, and there is still time for trades to settle and for custodians to process anything you decide to do. Doing the review in January means guessing at income you have not earned yet. Doing it on 20 December means finding out that a wire takes three days.
A short agenda covers most of it. Confirm any required distribution has been or will be satisfied. Estimate the year’s taxable income and compare it against the current bands to see what room remains. Check whether you are near an income-linked threshold that a discretionary withdrawal would push you across. Look at the unrealized gain in your taxable lots and identify which are cheapest to sell. Decide whether to fill room with a withdrawal, a conversion, or neither. Our walkthrough on running a financial checkup covers a broader version of the same habit.
Common mistakes to avoid
Most sequencing failures come from a small set of recurring errors, and each is avoidable with an annual review rather than specialist knowledge.
- Following taxable-first so strictly that low bands go unused. Years of near-zero taxable income look efficient and quietly waste cheap room that never comes back, leaving a larger pre-tax balance to be forced out later.
- Ignoring cost basis when picking what to sell. The account total tells you nothing about the tax. Individual lots differ, and the cheapest sale is rarely the default one your brokerage picks.
- Converting or withdrawing before satisfying a required distribution. In a required year the first money out counts toward the requirement and is not eligible for conversion. Order matters within the year, not only across years.
- Forgetting that pre-tax income drags benefit taxation with it. The headline band understates the true cost of a pre-tax withdrawal once a Social Security benefit is in payment.
- Crossing a premium surcharge threshold for a trivial amount. The steps are cliffs, not slopes, and the extra cost applies for a full year with a lag that makes it easy to forget.
- Spending Roth money early because it feels tax-free. It is tax-free, and that is exactly why it is the worst bucket to spend first in most years.
- Setting the order once and never revisiting it. Bands, thresholds, balances and rules all move. A sequence that fitted your first retirement year may fit badly by your fifth.
The bottom line
Withdrawal order is a lever most retirees hold without noticing. The conventional sequence of taxable, then tax-deferred, then Roth exists because it usually pays the lowest tax on this year’s spending while leaving the best-sheltered money compounding longest, and for a household with steady income and balances spread across all three buckets it is a reasonable default. What turns a default into a plan is knowing when to break it: filling a lower band deliberately in the low-income bridge years, using Roth money to stay under an income-linked threshold, and reducing the pre-tax balance before required distributions remove your discretion over it. The illustrative household above cut a 70,000 dollar year’s tax bill from about 15,400 dollars to about 3,780 dollars by blending rather than emptying one account, and repeated annually that gap compounds into real money. Every rate, band, balance and dollar figure here is illustrative and chosen to make the arithmetic legible, because tax rates, income thresholds, surcharge steps and distribution starting ages are all set by law and change. Confirm the current figures with the IRS or a qualified tax professional before acting on any of it. Run your own balances in the companion on this page, and test the long-run effect in our savings calculator.
Everything above is educational content about how account tax treatment interacts with spending, and none of it is tax, legal, financial or investment advice or a recommendation for any individual. The marginal rates of 12, 22 and 24 percent, the 15 percent long-term gains rate, the one third gain fraction, the 300,000, 600,000 and 200,000 dollar balances, the 70,000 dollar spending figure, the 24.0 life expectancy factor and every dollar amount derived from them were invented to make a mechanism visible and bear no relationship to your accounts. Marginal bands, long-term gains rates and their thresholds, the formula determining how much of a Social Security benefit is taxable, income-related Medicare premium surcharges and their steps, the starting age for required distributions, the early withdrawal age and its exceptions, health savings account rules, and the treatment of inherited accounts and cost basis on death are all set by legislation and administrative rulemaking, are revised from time to time, and depend on filing status and residence. Withdrawal sequencing also has consequences that are not shown here, including state income tax, health insurance subsidy eligibility before Medicare, and estate planning. Before changing where your retirement spending comes from, confirm the rules that currently apply to your own accounts and take advice from a qualified professional such as a certified public accountant, an enrolled agent, or a fee-only financial planner.
Frequently asked questions
What is the standard retirement withdrawal order?
The sequence most often described as the default is taxable accounts first, then tax-deferred accounts such as a traditional 401(k) or IRA, then Roth accounts last. The reasoning is that a dollar pulled from a taxable brokerage account is usually the cheapest to access, because only the gain portion is taxed and long-term gains have historically carried their own rate structure. Spending taxable money first also leaves the sheltered accounts compounding for longer. This default is a starting point rather than a rule, and several common situations, including required distributions and years when your income is unusually low, justify departing from it. Confirm the tax treatment that applies to your accounts with a qualified tax professional before you build a schedule around any sequence.
Why should you withdraw from taxable accounts first in retirement?
Two reasons stack up. The first is the tax on the withdrawal itself. When you sell in a taxable brokerage account you are only taxed on the gain, not on the money you originally invested, so a sale of 40,000 dollars with an illustrative one third gain portion exposes about 13,200 dollars to tax rather than the full amount. The second reason is what happens to everything you did not touch. Money left in a traditional or Roth account keeps compounding without annual tax drag, while a taxable account is taxed on dividends and realized gains every year regardless. Drawing the least sheltered pot first therefore buys shelter time for the more sheltered ones. Both figures here are illustrative.
Do required minimum distributions override your withdrawal order?
Yes, in practical terms. Once required distributions begin on your traditional accounts, the required amount comes out whether or not your sequencing plan wanted it to. That is why the years before the requirement starts carry so much planning value, because they are the only years in which the size of the pre-tax balance can still be reduced voluntarily and cheaply. A required distribution also has to be satisfied before any conversion in that year, since the first money out of the account in a required year counts toward the requirement. Our separate explainer covers how the requirement is calculated and which accounts it attaches to, and the starting age has been changed by legislation more than once, so confirm the current rule.
What is bracket filling in retirement withdrawals?
Bracket filling means deliberately taking more from a pre-tax account than you strictly need in a low income year, in order to use up the space in a lower marginal band before that space expires at the end of the year. Unused low-rate room does not carry forward. If your ordinary income falls well short of the top of a lower band, taking an extra pre-tax withdrawal or converting an equivalent amount to Roth taxes those dollars at that lower rate instead of leaving them to be taxed later at a higher one. The bands themselves are set annually and change, so the amount of room in your case has to be looked up rather than estimated. This is a mechanism, not a recommendation, and it interacts with other income-linked thresholds.
Should you ever spend Roth money before traditional money?
Sometimes, and the usual trigger is a single large expense in a year when your income is already high. If you need a lump sum for a roof or a car and taking it from a traditional account would push a large slice of income into a higher band or across an income-linked threshold, drawing part of it from a Roth account can be the cheaper route even though the default sequence says otherwise. Roth money is also the natural source for smoothing income in a year when you are close to a cliff. The counterargument is that Roth dollars are the most valuable ones you own, so spending them early gives up compounding in the account with the best tax treatment. Weigh both with a qualified adviser.
How does Social Security change the withdrawal order?
It changes it in two ways. The first is timing. A retiree who stops working before claiming a benefit has a window of unusually low taxable income, and that window is normally the cheapest time to draw or convert pre-tax money. The second is the way benefit taxation works. The share of a Social Security benefit that becomes taxable rises with other income, so an extra pre-tax withdrawal can pull additional benefit dollars into the tax base at the same time, making the effective cost of that withdrawal higher than the headline rate suggests. The thresholds involved are set by statute and are not routinely adjusted, so look up the current figures rather than relying on a remembered number.
Is there a downside to leaving a large taxable account untouched?
There can be. A taxable account is taxed on its dividends and realized gains every year, so leaving it untouched does not buy shelter the way leaving a Roth account untouched does. Against that, taxable holdings have historically received a basis adjustment when they pass to heirs, which is a genuine argument for keeping appreciated positions rather than selling them. The two pull in opposite directions and the balance depends on your estate picture, your unrealized gain, and how much of the account throws off taxable income each year. Because the inheritance side is governed by rules that legislation can change, treat that argument as a factor to check with a professional rather than a settled conclusion.
How often should you revisit your withdrawal order?
Once a year is the usual rhythm, and the useful moment is autumn, when you can see most of the year's actual income and still act before the year closes. The annual review is where you check how much low-rate room is left, whether a conversion still makes sense, whether any required distribution has been satisfied, and whether a market fall has changed which holdings are cheapest to sell. Doing it in January instead means guessing, and doing it in late December leaves no time for trades to settle. Sequencing is not a plan you set once and follow for twenty years, because the tax rules, your income, and your balances all move.
