The usual retirement advice is simple: spend cash and taxable investments first, then touch your 401(k) later. Yet for some retirees, protecting that 401(k) for too long creates a bigger tax bill just when Social Security and required withdrawals begin.
A large traditional 401(k) can turn into a second taxable paycheck in your 70s, even if you do not need the extra cash.
That is why some households deliberately draw down their 401(k) early, while income is lower and they have more control over timing. The approach can work, but only if taxes, health coverage, and investment risks are considered together.
Why Would Someone Spend Their 401(k) First?
At first, the strategy sounds backward. After decades of saving, why would a retiree deliberately start reducing the account that helped build their financial security?
The answer often comes down to one overlooked distinction: paying less tax this year is not necessarily the same as paying less tax throughout retirement. A traditional 401(k) allows earnings to grow without current income taxes, but most withdrawals eventually become taxable income.
That creates a choice. Retirees can leave the account untouched and postpone those taxes, or they can gradually withdraw money during years when their taxable income is relatively low.
The second approach is sometimes called a tax bracket management strategy. Rather than avoiding withdrawals altogether, a retiree deliberately recognizes a manageable amount of income each year.
Consider a hypothetical retiree who stops working at 62 with $800,000 in a traditional 401(k). Their salary disappears, but Social Security has not started, and required minimum distributions are still years away.
Those early retirement years may offer an opportunity to withdraw money at relatively favorable tax rates. Waiting until the account grows larger and other income sources begin could reduce that flexibility.
Four Common Withdrawal Approaches
There is no single withdrawal order that works for everyone. The following comparison shows why households with similar savings can reasonably choose different approaches.
| Withdrawal approach | Main advantage | Main drawback |
|---|---|---|
| Taxable savings first | Preserves tax-deferred investments | May create larger future RMDs |
| Traditional 401(k) first | Uses lower tax brackets early | Creates taxable income immediately |
| Roth savings first | Qualified withdrawals avoid current federal income tax | Uses up future tax-free flexibility |
| Blended withdrawals | Balances taxes across accounts | Requires yearly planning |
A blended strategy often deserves particular attention. It allows a retiree to combine taxable savings, traditional retirement accounts, and Roth assets rather than relying completely on one account.
Importantly, withdrawing from a 401(k) first does not necessarily mean spending the money immediately. Some retirees use those distributions for living costs, while others reinvest the amount remaining after taxes in a taxable investment account.
The First Years of Retirement May Offer a Valuable Tax Opportunity
For many households, taxable income changes sharply after work ends. Employment income disappears, but Social Security, pension payments, and mandatory retirement distributions may not have fully begun.
That creates what financial planners sometimes call a retirement tax window. It is a period when retirees may have more control over how much income appears on their federal tax returns.
Imagine someone retiring at age 62 with a substantial traditional 401(k), modest pension income, and enough savings to delay Social Security. Their taxable income might be considerably lower than it was during their final working years.
A planned 401(k) withdrawal could use some of that available room in a lower tax bracket. The retiree would pay tax now, but might reduce the amount subject to tax during later retirement years.
The important point is that this opportunity does not depend on predicting future tax laws. It depends on comparing a household’s expected income now with its likely income after Social Security and required withdrawals begin.
How the 2026 Tax Brackets Make This Strategy Work
Federal income taxes are progressive, meaning different portions of taxable income face different rates. Moving into a higher bracket does not cause every dollar of income to be taxed at that higher rate.
For the 2026 tax year, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. The 12% federal bracket extends through $50,400 of taxable income for single filers and $100,800 for joint filers.
This creates room for some retirees to make traditional 401(k) withdrawals before reaching a higher marginal tax bracket. The amount of available room depends on their other income and deductions.
A Hypothetical Retiree’s 2026 Tax Calculation
Consider a single retiree age 62 who receives $36,000 annually from a fully taxable pension. Assume the retiree has no Social Security income, other taxable income, tax credits, or deductions beyond the standard deduction.
Under those assumptions, the following table estimates federal income taxes at different traditional 401(k) withdrawal amounts.
| Annual 401(k) withdrawal | Taxable income | Estimated federal tax | Extra tax from withdrawal |
|---|---|---|---|
| $0 | $19,900 | $2,140 | $0 |
| $20,000 | $39,900 | $4,540 | $2,400 |
| $30,500 | $50,400 | $5,800 | $3,660 |
| $40,000 | $59,900 | $7,890 | $5,750 |
Calculations use 2026 federal tax brackets and the single standard deduction. They exclude state income taxes and other tax adjustments.
The first $30,500 of additional withdrawals fits within the retiree’s remaining 12% federal bracket. Beyond that amount, the next dollars enter the 22% bracket.
This does not automatically make a $30,500 withdrawal the best choice. It shows how the tax cost of additional withdrawals changes as income rises.
For someone expecting substantially higher taxable income later, using part of a lower bracket today could be worthwhile. For someone expecting lower taxes in the future, preserving the 401(k) may be preferable.
A Smaller 401(k) Can Mean Smaller Required Withdrawals Later
One major reason retirees draw down traditional retirement accounts early is to reduce future required minimum distributions, commonly called RMDs.
RMDs are minimum amounts that tax law generally requires account owners to withdraw from certain retirement accounts each year. The money withdrawn is ordinarily taxable to the extent it represents pretax contributions and earnings.
Under the current rules, the applicable RMD starting age is generally:
- Age 73: People born from 1951 through 1959.
- Age 75: People born in 1960 or later.
Special rules can allow some people who continue working to delay RMDs from their current employer’s retirement plan. This exception does not generally apply to traditional IRAs.
The concern is straightforward. If a traditional 401(k) remains untouched for many years, investment growth could make the eventual required withdrawals larger.
What a Smaller Balance Does to an RMD
The IRS generally calculates an RMD by dividing the prior December 31 account balance by an applicable life expectancy factor. A smaller balance produces a smaller required withdrawal when the same factor applies.
The following examples use the standard Uniform Lifetime Table, assuming no special spouse-related calculation applies.
| Age | Prior year-end balance | IRS divisor | Annual RMD |
|---|---|---|---|
| 73 | $800,000 | 26.5 | $30,189 |
| 73 | $600,000 | 26.5 | $22,642 |
| 75 | $800,000 | 24.6 | $32,520 |
| 75 | $600,000 | 24.6 | $24,390 |
These are hypothetical balance comparisons, not forecasts of what an account will be worth at a particular age. Future market returns, withdrawals, contributions, and account transfers would affect actual balances.
Still, the calculation reveals why some retirees prefer to reduce large traditional accounts before RMDs begin. At age 75, the difference between an $800,000 balance and a $600,000 balance is approximately $8,130 in required annual withdrawals.
An RMD does not mean the retiree must spend the money. After satisfying taxes, any remaining funds can generally be invested in a taxable account.
However, the distribution itself may increase taxable income. That can affect other retirement costs even when the retiree does not need the cash for living expenses.
Drawing From a 401(k) Can Help Delay Social Security
Some retirees withdraw from their 401(k) first because they want to postpone Social Security. This decision can trade additional portfolio withdrawals today for a larger monthly government benefit later.
Social Security retirement benefits can begin as early as age 62, but claiming before full retirement age permanently reduces the monthly starting benefit. Waiting beyond full retirement age increases the benefit through delayed retirement credits until age 70.
For people born in 1960 or later, full retirement age is 67. Delaying from 67 to 70 increases the benefit by 24%, before considering annual cost of living adjustments.
What Delaying Benefits Could Mean
Suppose a hypothetical retiree has a full retirement age benefit of $2,400 per month. The table illustrates how the monthly amount changes depending on the age at which benefits begin.
| Claiming age | Monthly benefit | Annual benefit |
|---|---|---|
| 62 | $1,680 | $20,160 |
| 67 | $2,400 | $28,800 |
| 70 | $2,976 | $35,712 |
Illustration assumes a full retirement age of 67 and expresses amounts in constant dollars, excluding future cost of living adjustments and individual benefit recalculations.
The difference between claiming at 67 and waiting until 70 is $576 per month, or $6,912 annually. That larger benefit continues for life and can also influence survivor benefits for a married household.
However, delaying benefits is not free. In this example, a retiree who waits from age 67 to 70 gives up approximately $86,400 in payments over those three years, before considering cost of living adjustments.
Ignoring taxes, investment returns, and other adjustments, the additional $576 monthly benefit would take about 12.5 years after age 70 to recover the missed payments. That places the simple break-even age around 82½.
Someone with substantial savings, good health, and a long expected retirement might consider using 401(k) withdrawals to bridge that period. Someone with urgent cash needs or a shorter expected lifespan may reasonably choose otherwise.
For married couples, the higher earner’s claiming decision can be especially important. A larger benefit may provide valuable income protection to the surviving spouse.
Roth Conversions Offer Another Way to Reduce Future 401(k) Taxes
Not every early drawdown involves taking money out and spending it. Some retirees move pretax retirement savings into a Roth IRA through a Roth conversion.
A conversion generally creates taxable income in the year it occurs. In exchange, the converted money enters an account where future qualified withdrawals can be tax-free.
Unlike traditional IRAs, Roth IRAs are not subject to lifetime RMDs for the original owner. Designated Roth 401(k) accounts also generally have no lifetime RMD requirement for the original owner.
Consider a retiree with $700,000 in a traditional 401(k) and enough cash outside retirement accounts to pay their living expenses. Instead of making large taxable withdrawals later, the retiree might convert smaller amounts over several lower-income years.
For example, converting $25,000 annually for four years would move $100,000 into Roth accounts before considering investment changes. The amount converted would generally be included in taxable income during those four years.
This strategy can provide several possible advantages. It may reduce future RMDs, give retirees access to more tax-free assets later, and help a surviving spouse manage taxable income.
But a Roth conversion is not automatically a tax-saving move. A large conversion can push income into higher brackets, affect healthcare costs, or reduce eligibility for income-based deductions.
Converted funds also have applicable Roth withdrawal rules, including five-year requirements in certain situations. Roth conversions generally cannot be reversed under current law.
The real decision is whether paying tax on the conversion today is preferable to paying tax on future withdrawals. That requires comparing more than one tax year.
The Medicare Trap That Can Make Early Withdrawals Expensive
A retirement withdrawal strategy should account for healthcare costs, especially after age 65. One overlooked factor is Medicare’s income-related monthly adjustment amount, known as IRMAA.
IRMAA raises Medicare Part B and Part D costs for beneficiaries whose income exceeds certain thresholds. Because the charges are based on modified adjusted gross income, large traditional 401(k) withdrawals and Roth conversions can contribute to higher premiums.
In 2026, the first IRMAA threshold is above $109,000 for individual filers and $218,000 for married couples filing jointly. The standard Medicare Part B monthly premium is $202.90.
An individual in the first higher-income tier pays $284.10 monthly for Part B, plus a $14.50 monthly Part D income adjustment if enrolled in Part D. Together, those surcharges equal $95.70 per month, or $1,148.40 over a full year.
That creates a potential problem. A withdrawal that looks sensible from an income tax perspective may become less attractive after additional Medicare premiums are considered.
Why the Two-Year Lookback Matters
Medicare generally uses income reported on a federal tax return from two years earlier to determine IRMAA. For example, 2026 Medicare premiums generally reflect income from the 2024 tax year.
Similarly, a large withdrawal during 2026 could affect Medicare premiums in 2028. The actual 2028 thresholds and premiums will depend on the rules and amounts applicable to that year.
Some people experiencing a qualifying life-changing event, such as work stoppage or reduced work hours, can request a new IRMAA determination. However, ordinary voluntary withdrawals and conversions do not automatically qualify for that relief.
A good withdrawal plan should therefore examine both the immediate income tax cost and the possible healthcare cost two years later.
Retiring Before 65 Creates a Different Health Insurance Problem
People who retire before qualifying for Medicare may purchase coverage through the Affordable Care Act Marketplace. Their eligibility for premium tax credits depends in part on household income.
HealthCare.gov generally counts most traditional 401(k) and IRA withdrawals as income for this purpose. Qualified Roth distributions are generally treated differently.
Imagine someone retiring at 62 and expecting relatively modest taxable income. A sudden $70,000 traditional 401(k) withdrawal could significantly change the household income used to calculate Marketplace financial assistance.
That may increase the effective cost of the withdrawal beyond ordinary income taxes. The result depends on household size, income, coverage, and the Marketplace rules applicable to the coverage year.
This is one reason early 401(k) withdrawals should not be treated as automatically favorable just because a retiree has stopped working. The years before Medicare eligibility require their own healthcare and tax analysis.
Withdrawing Before Social Security May Simplify Its Tax Treatment
Social Security adds another layer to retirement tax planning. Depending on other income, a portion of retirement benefits may become taxable.
Under federal rules, up to 85% of Social Security benefits can be included in taxable income. This does not mean beneficiaries pay an 85% tax rate on their Social Security checks.
For many filers, the relevant combined-income thresholds begin at $25,000 for individuals and $32,000 for married couples filing jointly. Higher thresholds of $34,000 and $44,000, respectively, help determine when up to 85% of benefits may become taxable.
Traditional 401(k) distributions generally increase the income used in these calculations. Therefore, taking substantial withdrawals after Social Security starts may cause a larger share of benefits to become taxable.
Some retirees respond by making controlled withdrawals during the years before benefits begin. They use lower-income years to reduce pretax retirement balances while postponing the interaction between large account distributions and Social Security taxation.
However, this consideration alone does not justify delaying Social Security. Claiming age should also reflect health, household income, survivor needs, and the amount of savings available to fund the delay.
The Biggest Risk: Selling Investments When Markets Fall
Taxes are only one part of a successful retirement withdrawal strategy. Investment losses early in retirement can also change how long savings last.
This is called sequence-of-returns risk. It occurs when poor investment returns arrive during the same period that someone is regularly withdrawing money.
Consider a hypothetical portfolio worth $600,000 at retirement. Assume a retiree withdraws $40,000 at the end of each year.
If the portfolio loses 20% in the first year and gains 20% in the second, the ending balance after both withdrawals would be $488,000. Reverse the return order, gaining 20% first and losing 20% second, and the ending balance would be $504,000.
The two examples have the same investment returns and the same total withdrawals. Yet their ending balances differ by $16,000 because the withdrawals occurred at different portfolio values.
This is why a strategy built around early 401(k) withdrawals must also address investment risk. A retiree may benefit from holding an appropriate reserve of cash and short-term, high-quality investments for upcoming expenses.
That reserve can reduce the need to sell stocks during a downturn. It does not eliminate market risk, but it may help prevent an otherwise reasonable withdrawal strategy from becoming unsustainable.
Why Spending the Entire 401(k) First Can Backfire
There is an important difference between gradually reducing a traditional 401(k) and draining it as quickly as possible. The first can be a tax planning strategy, while the second may leave a retiree exposed to unnecessary risk.
Large Withdrawals Can Trigger Higher Taxes
Traditional 401(k) withdrawals generally count as ordinary income. Taking $150,000 in one year may create a very different tax outcome than spreading a similar amount across several years.
A large distribution can also affect deductions and other income-based calculations. For 2025 through 2028, eligible taxpayers age 65 or older may qualify for an additional federal senior deduction of up to $6,000 per person.
That deduction begins phasing out when modified adjusted gross income exceeds $75,000 for individuals or $150,000 for joint filers. Increasing withdrawals can therefore reduce the deduction available to some older taxpayers.
Future Tax Rates May Actually Be Lower
Not everyone faces higher tax rates later in retirement. Some households expect smaller pensions, reduced spending, or a lower taxable income after they stop working.
For those retirees, preserving tax-deferred assets may be reasonable. Paying tax earlier than necessary could provide no financial advantage.
Early Withdrawals Can Create Penalties
Traditional 401(k) distributions before age 59½ generally face a 10% additional federal tax unless an exception applies. One important exception may apply to certain withdrawals from an employer plan after separating from service during or after the calendar year the employee turns 55.
That particular exception generally does not carry over to an IRA after a rollover. Anyone retiring in their late 50s should review the distribution rules before moving workplace retirement money.
Some Accounts Deserve Different Treatment
A taxable brokerage account may contain investments eligible for favorable long-term capital gains rates. Spending some of those assets before traditional 401(k) money may be more tax-efficient in certain circumstances.
Roth accounts provide another form of flexibility. Qualified Roth withdrawals can often cover unexpected expenses without adding federal taxable income, which may become especially valuable later.
A Lower Tax Bill Does Not Guarantee More Retirement Wealth
A retiree could successfully reduce future RMDs and still end up with less money if the early withdrawals are too large. Inflation, weak markets, healthcare expenses, and a long lifespan remain important considerations.
Taxes should support the retirement plan, not control every decision. An effective strategy balances lifetime taxation with sustainable spending and adequate financial reserves.
How to Decide Which Account to Withdraw From First
The strongest retirement withdrawal plans consider several factors before selecting an account. The goal is not to follow a rigid rule but to coordinate taxes, income, investments, and expected future needs.
The following decision table provides a practical starting point.
| Your situation | What to consider | Main caution |
|---|---|---|
| Recently retired with low taxable income | Controlled traditional 401(k) withdrawals | Avoid unnecessary higher tax brackets |
| Large traditional 401(k) and many years before RMDs | Gradual withdrawals or Roth conversions | Compare current and future tax costs |
| Planning to delay Social Security | Use some retirement savings as temporary income | Check longevity and portfolio risk |
| Receiving Marketplace health coverage | Coordinate withdrawals with annual income | Financial assistance may change |
| Already paying Medicare premiums | Review IRMAA effects | Income may affect future premiums |
| Significant Roth and taxable savings | Blend withdrawals across account types | Preserve future tax flexibility |
No single row should determine the complete decision. A household may fit several situations at once, making a combination of withdrawal approaches more suitable than any one strategy.
For example, someone with a large 401(k), a smaller taxable investment account, and future pension income may benefit from a different schedule than someone relying almost entirely on Social Security.
