For many business owners and high-income professionals, the answer to a 401(k) contribution is yes, but not automatically.
A traditional 401(k) can provide an immediate income-tax deduction, employer contributions, and decades of tax-deferred investment growth. Those benefits can make it one of the most effective long-term accumulation vehicles available. The mistake is assuming that because a 401(k) is good at accumulating wealth, maximizing one must also produce the best lifetime after-tax result.
Whether a 401(k) is worth it depends on more than the tax deduction you receive today. You also have to consider the tax rate that may apply when the money comes out, required minimum distributions, Roth conversion opportunities, Medicare IRMAA, liquidity needs, and what happens if the account is eventually inherited by your children.
For business owners, the question becomes even more complicated because retirement contributions compete with other uses of capital. Money contributed to a retirement plan may otherwise be available to invest in the business, purchase another company, build taxable investments, reduce debt, or preserve liquidity. Retirement planning therefore should not be separated from tax planning, business cash flow, compensation, and long-term estate goals.
To understand why, it helps to understand what a traditional 401(k) actually does and where it came from.
How the 401(k) Became America’s Default Retirement Account
Section 401(k) was added to the Internal Revenue Code in 1978 as Congress addressed the tax treatment of certain cash-or-deferred compensation arrangements. It was not originally conceived as a comprehensive replacement for the traditional pension system or as the centerpiece of American retirement planning. The provision dealt fundamentally with when compensation would be recognized for income tax purposes. Benefits consultant Ted Benna subsequently recognized that the provision could be used more broadly and, in 1981, implemented what is generally regarded as the first modern 401(k) plan by combining employee salary deferrals with employer contributions.
That history matters because it helps clarify what a traditional 401(k) actually does. It does not generally eliminate the income tax associated with compensation. It changes when that income is recognized for federal income tax purposes. An employee receives an immediate benefit by deferring current taxable income, while the income tax consequences are generally moved into the future when distributions are taken.
There is nothing inherently undesirable about that arrangement. Tax deferral can be extremely valuable. A dollar of tax that does not have to be paid today can remain invested for decades, and the earnings generated inside the account are not generally subjected to annual taxation while they remain in the plan. The mistake is not using tax deferral. The mistake is assuming that because the immediate benefit is easy to measure, the long-term result must automatically be favorable.
Consider an employee who can contribute $10,000 to a traditional 401(k) while facing a 25% marginal federal income tax rate. Ignoring other taxes and limitations for purposes of the example, taking the $10,000 as taxable compensation could leave approximately $7,500 available to invest after federal income tax. Deferring the entire $10,000 into a traditional 401(k), however, allows the full amount to remain invested. Compared with the $7,500 available after paying a 25% tax, the retirement account begins with approximately 33% more investable capital.
That is a significant advantage, particularly when the additional capital compounds for several decades. It also explains why traditional 401(k) contributions are so appealing during the accumulation stage of financial planning. The current tax deduction is visible, the larger investment contribution is visible, and the growing account balance is visible.
The future tax liability is not.
Is Your 401(k) Really Worth Its Statement Balance?
This distinction becomes increasingly important as an investor approaches retirement. Someone may reach their 60s or 70s with $500,000, $1 million, or several million dollars accumulated in traditional retirement accounts. After decades of watching those balances increase, it is natural to think of the number appearing on the statement as personal wealth available for future consumption.
Economically, however, a traditional pretax account is different from an account containing money on which the income tax has already been paid. Taxable distributions from a traditional 401(k) generally become ordinary income when withdrawn. The precise future liability cannot be shown on the account statement because it depends on future tax law, the taxpayer’s other income, the timing of distributions, deductions, filing status, state taxation, and numerous other factors.
Nevertheless, the fact that the liability cannot be precisely calculated today does not mean it should be ignored.
This is where I think the conventional 401(k) discussion becomes incomplete. We spend decades helping people answer the accumulation question: How much can I contribute and how large can I make this account? Far less attention is given to the distribution question: How much of this account will ultimately be available for me or my family after income taxes are considered?
Those are not the same question.
When Is a Traditional 401(k) Worth It?
The traditional argument for tax-deferred retirement saving assumes that the taxpayer will receive a deduction while working at a relatively high marginal tax rate and recognize the income later at a lower rate. When that occurs, the traditional 401(k) can produce an additional benefit beyond simply delaying the tax.
Suppose, for example, that someone defers compensation while facing a 32% marginal tax rate but eventually recognizes those dollars during retirement at an effective rate closer to 15% or 20%. In that situation, the taxpayer has not merely postponed taxation. They may have shifted income from a relatively expensive tax environment into a substantially less expensive one.
That is good tax planning.
The problem arises when we assume that this outcome will occur without actually analyzing it.
A financially successful retiree may have considerably more taxable income than expected. Social Security benefits, pensions, rental properties, investment income, traditional IRAs, business interests and decades of accumulated retirement savings can all contribute to taxable income after employment ends. A person may retire from a job without necessarily retiring into a low tax bracket.
There is also an inherent paradox in successful tax-deferred saving. The more successfully an investor contributes and compounds money inside traditional retirement accounts, the larger the pool of income becomes that has not yet been subjected to federal income tax. A multimillion-dollar traditional retirement account is certainly preferable to having inadequate retirement savings, but it can also create a significant future tax-planning obligation.
This does not mean the investor made a mistake. It means the accumulation strategy eventually needs to become a distribution strategy.
Traditional 401(k) vs. Roth 401(k): The Tax Rate Matters
One of the easiest ways to understand this is to compare traditional and Roth treatment under simplified assumptions. Suppose an individual has $10,000 of income available for retirement saving and faces a 25% income tax rate today. A traditional contribution allows the entire $10,000 to be invested. A Roth contribution requires the taxpayer to pay the $2,500 tax today, leaving $7,500 available for investment.
Assume both investments subsequently increase tenfold. The traditional account grows to $100,000, while the Roth account grows to $75,000. If the traditional account is eventually taxed at exactly 25%, the taxpayer is left with $75,000 after tax. Under these simplified assumptions, the two strategies produce the same after-tax result.
That is why arguing that traditional 401(k)s are inherently bad because distributions are taxable is incorrect. If the tax rate is identical on both sides of the transaction, the timing of the tax alone does not create a mathematical advantage for Roth treatment.
The important variable is the tax rate.
If you receive a deduction at 35% today and ultimately recognize the income at 20%, traditional deferral can be extremely attractive. If you receive a deduction at 12% today and eventually recognize the income at 30%, the result can move in the opposite direction. Future tax rates are impossible to know with certainty, but that uncertainty is an argument for planning and diversification, not for ignoring the issue.
The appropriate question therefore is not simply whether a traditional 401(k) is good. It is whether the tax deduction you are receiving today is valuable enough relative to the tax liability you are agreeing to recognize later.
Is a 401(k) Still Worth It as You Approach Retirement?
For someone in their 30s or 40s, the future tax consequences of a traditional 401(k) can feel distant. The immediate benefits are much easier to see. Contributions can reduce current taxable income, an employer may provide a matching contribution, and investment earnings can compound inside the plan without creating annual taxable income. If the account is growing steadily, the strategy appears to be working exactly as intended.
As retirement approaches, however, the deferred side of the transaction becomes much more important. Someone who retires with $2 million spread across traditional 401(k) and IRA accounts has accumulated substantial wealth, but they have also accumulated a large pool of income that generally has not yet been subjected to federal income tax. At that point, the planning question changes from how efficiently the account can grow to how efficiently the account can ultimately be distributed.
This is an important distinction between investment management and wealth planning. Investment management is largely concerned with allocating capital, controlling costs, managing risk, and producing an appropriate return. Wealth planning has to go further. It must consider how those assets will eventually be converted into spending, how distributions will affect the taxpayer’s overall income, and what happens to the assets that remain at death. A retirement account can be managed exceptionally well from an investment standpoint while still producing an inefficient tax result if the distribution side is never adequately planned.
A retiree with a large traditional 401(k) may also have Social Security, a pension, rental income, investment income, business interests, or other sources of taxable income. It is therefore a mistake to assume that retirement automatically produces a low-income tax environment. In many successful households, the end of employment eliminates wages but does not eliminate taxable income. The traditional retirement accounts that provided valuable deductions during the accumulation years can themselves eventually become one of the largest sources of taxable income during retirement.
Required Minimum Distributions Reduce Some of the Control You Once Had
Required minimum distributions make this issue more visible because the taxpayer eventually loses some control over when traditional retirement income is recognized. Under current law, many taxpayers are required to begin distributions from traditional retirement accounts at age 73, with the applicable starting age eventually increasing to 75 for younger cohorts. The exact rules depend on the taxpayer and account involved, but the broader planning issue is straightforward. At some point, the government may require taxable distributions even when the retiree does not actually need the money for current living expenses.
Consider someone who accumulated a substantial traditional retirement account but lives modestly in retirement. Social Security, a pension, and taxable investments may already provide enough cash flow to support their lifestyle. From a purely personal spending perspective, they may prefer to leave the retirement account untouched. Required minimum distributions can prevent that strategy from continuing indefinitely because a portion of the account must eventually be distributed and included in taxable income.
The tax consequences can extend beyond the income tax imposed directly on the retirement distribution. Additional income may affect the taxable portion of Social Security benefits, Medicare income-related premium adjustments, the taxation of investment gains, deductions, charitable planning, and other parts of the taxpayer’s financial situation. This is why I do not view an RMD calculation as a retirement strategy. It tells the taxpayer the minimum amount federal law requires to be distributed. It does not tell the taxpayer whether that amount, or only that amount, produces the best long-term result.
By the time the first RMD occurs, some of the best planning opportunities may already have passed. A person who waits until their 70s to begin thinking seriously about how traditional retirement assets will be distributed may discover that several years of lower taxable income immediately after retirement could have been used much more strategically.
Roth Conversions Before RMDs Can Change the 401(k) Tax Equation
Suppose someone retires at 62 after spending decades earning a substantial salary. Their wages disappear, but they have not yet started Social Security and required minimum distributions are still years away. Depending on their other income and assets, their taxable income may fall dramatically during this period. Those lower-income years can create an opportunity to intentionally recognize some of the income that has been deferred inside traditional retirement accounts.
One possibility is to take distributions before they are required. Another is to convert a portion of traditional retirement assets to Roth. Either strategy intentionally creates taxable income today, which can initially seem counterproductive to someone who spent an entire career trying to reduce taxable income. The objective, however, is not simply to minimize the current year’s tax return. The objective is to determine whether paying tax at a known and relatively favorable rate today could reduce the amount eventually subjected to a higher rate later.
Roth Conversions Accelerate Tax Rather Than Eliminate It
This is the appropriate way to think about Roth conversions as well. A Roth conversion does not make a tax liability disappear. It accelerates the recognition of income. The taxpayer voluntarily pays tax on a traditional retirement balance today in exchange for moving those assets into a structure where qualified future distributions may be tax-free. Whether that decision makes sense depends largely on the relationship between the tax rate paid on the conversion and the rate that would likely apply if the income remained deferred.
IRMAA Can Change the Real Cost of a Roth Conversion
The analysis cannot stop at the federal income tax bracket, however. Once a retiree is enrolled in Medicare, additional income can also affect the Income-Related Monthly Adjustment Amount, commonly referred to as IRMAA. Medicare uses modified adjusted gross income to determine whether higher-income beneficiaries must pay additional premiums for Medicare Part B and Part D, and the determination is generally based on income reported two years earlier. As a result, a large Roth conversion in one year can potentially increase Medicare premiums two years later.
This creates another marginal cost that should be considered when deciding how much income to intentionally recognize. A conversion may still make economic sense even if it causes an IRMAA adjustment, particularly if the alternative is recognizing the same income later at substantially higher tax rates or allowing a much larger traditional balance to become subject to future RMDs. The mistake would be evaluating the conversion solely by asking whether there is room left in a particular federal income tax bracket.
IRMAA Thresholds Can Create Tax Planning Cliffs
IRMAA is also unusual because its income thresholds operate more like cliffs than ordinary marginal tax brackets. Crossing a threshold can increase Medicare premiums for the entire year rather than merely imposing an additional tax on the dollars above the threshold. That means a relatively small additional Roth conversion, capital gain, or other item of income can occasionally produce a disproportionately large increase in Medicare costs. For someone near an IRMAA threshold, the amount of a proposed Roth conversion should therefore be modeled rather than selected simply by filling the remaining space in a tax bracket.
Timing Matters Because IRMAA Uses a Two-Year Lookback
The two-year lookback also makes timing particularly important. A retiree completing conversions before becoming subject to Medicare may have a different planning opportunity than someone already enrolled in Medicare. Likewise, retirement itself can sometimes provide relief from an IRMAA determination because Social Security recognizes certain life-changing events, including the loss or reduction of work, when considering a request to use more recent income information. The availability of that relief depends on the circumstances and should not simply be assumed.
The Best Roth Conversion Strategy Depends on the Full Tax Picture
For a recently retired taxpayer whose taxable income has temporarily fallen, a partial Roth conversion can still be attractive if future Social Security benefits, pensions, and RMDs are expected to push taxable income materially higher. For someone still earning a substantial salary and already paying one of the highest marginal rates they expect to experience, the same conversion may be considerably less attractive. In either case, the appropriate analysis should consider the income tax generated today, the potential effect on Medicare premiums, the expected future tax rate, and the reduction in future tax-deferred balances. The strategy is not inherently good or bad. It is another decision about when income should be recognized and at what total cost.
Tax Diversification Can Matter as Much as Asset Diversification
Investors are routinely told not to concentrate all of their investments in one company, industry, or asset class. The same basic concept deserves consideration when deciding how wealth will eventually be taxed. A household that accumulates nearly all of its financial assets inside traditional retirement accounts may reach retirement with a substantial net worth but relatively little control over the tax character of future withdrawals.
Consider two retirees who each have $2 million of investable assets. The first has almost the entire amount inside traditional 401(k) and IRA accounts. The second has $900,000 in traditional retirement accounts, $500,000 in Roth accounts, $450,000 in taxable investments, and $150,000 in cash and short-term reserves. Their headline net worth may be identical, but their ability to manage taxable income can be considerably different.
The second retiree can potentially choose among several sources of capital depending on the circumstances of a particular year. Traditional retirement distributions can be used when there is room to recognize additional ordinary income at an acceptable rate. Roth assets may be available in years when generating additional taxable income would be undesirable. Taxable investments may allow the retiree to selectively realize long-term capital gains, while cash reserves can fund unusually large expenditures without creating taxable income at all.
None of those asset categories is universally superior. Their value comes partly from behaving differently. Tax diversification gives the retiree options, and those options can become especially valuable when tax brackets, Medicare premiums, Social Security, capital gains, charitable giving, and estate objectives are being coordinated simultaneously.
This is why maximizing a single retirement account should not necessarily be treated as the ultimate financial objective. Someone can accumulate a very large account and still arrive at retirement with an unnecessarily rigid financial structure. The better objective is to accumulate assets in a manner that preserves enough flexibility to respond to changing circumstances.
Business Owners Should Consider Liquidity Before Maxing a 401(k)
The tax advantages of retirement accounts can also cause people to undervalue liquidity. Money inside a 401(k) is not economically identical to money inside a taxable brokerage account, even when the underlying investments are the same. Retirement accounts are subject to plan provisions, distribution restrictions, and tax rules that can limit how easily the capital can be used.
This distinction becomes particularly important for someone who does not intend to follow a conventional retirement timeline. A person hoping to leave the workforce at 50 may need considerably more accessible capital than someone planning to work until 70. A business owner may need cash to acquire another company or capitalize an operating business. Another household may want flexibility to purchase real estate, assist adult children, or fund other substantial expenditures well before traditional retirement age.
Putting more money into a tax-advantaged account may increase projected retirement wealth while simultaneously reducing financial flexibility during the intervening decades. That does not mean the contribution is wrong. It means liquidity has economic value and should be included in the analysis rather than treated as an afterthought.
The same reasoning applies to the broader question of whether someone should continue maximizing a traditional 401(k). A taxpayer who already has significant tax-deferred savings but relatively little accessible wealth may reasonably decide that the next dollar serves a different purpose outside the retirement plan. Another taxpayer with substantial taxable assets and a very high current marginal tax rate may reasonably reach the opposite conclusion.
Your 401(k) Strategy Should Change as Your Financial Life Changes
One of the problems with financial rules of thumb is that they tend to turn a decision made under one set of circumstances into a permanent strategy. Someone who aggressively contributed to a traditional 401(k) while paying a 35% marginal tax rate may have made an excellent decision. Twenty years later, after retirement reduces their taxable income and the traditional account has grown substantially, intentionally converting some of that account to Roth may also be an excellent decision.
Those positions are not contradictory. They reflect changing circumstances.
Financial planning should be dynamic. Income changes, tax law changes, family circumstances change, retirement dates change, and estate objectives change. A strategy that was appropriate at 35 should be periodically reevaluated rather than automatically continued at 55 simply because it worked during the accumulation phase.
This is one reason I am skeptical of advice framed around permanent rules such as always maximizing a traditional 401(k), always choosing Roth, or always deferring taxes whenever possible. Each of those ideas can be correct under the right circumstances. None of them should substitute for understanding what the taxpayer is actually trying to accomplish.
Eventually a Retirement Account Can Become an Estate Asset
The tax planning question becomes even more important when the account owner is unlikely to spend the entire retirement balance. At that point, a traditional 401(k) or IRA is no longer solely a retirement asset. A meaningful portion of it has effectively become an estate asset.
Consider an individual in their 80s who owns a paid-off home, receives Social Security, has taxable investments, and maintains a large traditional retirement account. Their lifestyle requires only a fraction of their total assets, making it increasingly likely that a substantial portion of the retirement account will eventually pass to beneficiaries. The planning analysis should therefore begin to consider the tax position of those beneficiaries rather than focusing exclusively on the retiree’s current tax return.
This is where decades of tax deferral can create an outcome that was never seriously considered when the original contributions were made. The taxpayer may have received deductions during relatively moderate tax years, allowed the investments to compound for decades, and then died without recognizing much of the deferred income. The tax obligation did not disappear. The question simply becomes who recognizes the income next.
Why an IRA Matters in a 401(k) Discussion
Although this article focuses primarily on 401(k)s, the distinction between a 401(k) and an IRA often becomes less important as someone moves through their career and into retirement. When an employee leaves an employer, they may be permitted to leave the balance in the former employer’s plan, move it into a new employer’s retirement plan, or roll the balance into an IRA. Many retirees ultimately consolidate former employer retirement accounts into traditional IRAs because doing so can simplify administration and provide access to a broader range of investments and custodians.
That is why IRA beneficiary planning is relevant to a discussion about long-term 401(k) strategy. A worker may spend 30 years accumulating money inside several employer-sponsored 401(k) plans and eventually enter retirement with much of that same tax-deferred wealth held in one or more IRAs. The tax character of the money has not changed simply because the account was rolled over. Traditional pretax dollars generally remain tax deferred, and the eventual distribution and inheritance questions remain.
The rollover can, however, change the legal and administrative framework surrounding the account. Employer plans are governed by their plan documents and can involve rules that differ from IRAs, including spousal beneficiary protections. Once assets are held in an IRA, the IRA beneficiary designation and custodial agreement become especially important in determining who receives the account at death and what happens if no valid individual beneficiary has been named.
This is why beneficiary designations should not be treated as paperwork completed once and forgotten. Someone may carefully accumulate retirement assets for decades, consolidate those accounts after retirement, and unintentionally create a very different tax result for the next generation simply because the beneficiary designation was never revisited.
What Happens to Your 401(k) When Your Children Inherit It?
Under current law, many non-spouse beneficiaries who inherit traditional retirement accounts are generally required to distribute the inherited account over a relatively compressed period. For many designated beneficiaries, that means the account must be fully distributed within 10 years. That matters because the deferred income does not disappear when the account owner dies. It generally remains taxable as distributions are received, meaning the beneficiary may inherit both the asset and the deferred income-tax liability attached to it.
Heirs May Inherit the Account During Their Highest-Earning Years
The age at which children commonly inherit from their parents makes this especially important. A parent who dies at 85 may leave retirement assets to children who are 50, 55, or 60. Those years frequently coincide with the beneficiaries’ highest earning years. A child may already have substantial wages, business income, investment income, or a spouse with significant earnings when distributions from an inherited traditional retirement account are added on top of the household’s existing taxable income.
It is therefore entirely possible for a parent to have deferred income while facing a relatively modest marginal tax rate and eventually leave that same deferred income to a child who recognizes it at a materially higher rate. That result is not inevitable, and it certainly does not mean the parent’s original retirement contributions were a mistake. It does mean the tax analysis should extend beyond the deduction received in the year of contribution and, for families accumulating significant wealth, beyond the lifetime of the original account owner.
Beneficiary Designations Can Change the Tax Outcome
There is another complication that families often discover only after someone dies. Retirement accounts generally pass according to the beneficiary designation and the governing plan or custodial agreement, not simply according to the will. If an IRA owner fails to name a valid beneficiary and the custodial agreement provides that the estate becomes the default beneficiary, the estate can become the beneficiary of the IRA. That is generally less favorable than naming individual beneficiaries directly because an estate is not a designated beneficiary for purposes of the post-death distribution rules.
An Executor May Not Have to Liquidate the IRA Immediately
That does not necessarily mean the executor should immediately liquidate the retirement account, deposit the proceeds into the estate’s checking account, pay the resulting income tax, and distribute whatever remains to the heirs. In several private letter rulings, the IRS has permitted an estate or trust fiduciary to divide its beneficial interest in an IRA and arrange direct trustee-to-trustee transfers into separately titled inherited IRAs for the ultimate beneficiaries. When properly structured, those transfers themselves were not treated as taxable IRA distributions.
A Direct Transfer Can Preserve More Tax Flexibility
This distinction can be extremely important. Suppose an estate becomes the beneficiary of an $800,000 traditional IRA and the residue of the estate passes equally to four adult children. An immediate liquidation could result in a very large amount of ordinary income being recognized by the estate in a single year, where federal income-tax brackets become compressed very quickly. Depending on the governing documents, state law, and the custodian’s procedures, the executor may instead be able to have each child’s beneficial interest transferred directly into a properly titled inherited IRA. Each child could then recognize taxable income as distributions are received rather than forcing the entire deferred balance through the estate at once.
A Transfer Does Not Create a New 10-Year Period
There is an important limitation, however. Moving the estate’s interest into separate inherited IRAs does not rewrite history. If the estate was the beneficiary at the owner’s death, transferring the account to the estate beneficiaries generally does not retroactively make those individuals the decedent’s designated beneficiaries or give them a new 10-year distribution period. The inherited accounts generally retain the post-death distribution schedule that applied because the estate was the beneficiary in the first place.
Beneficiary Designations Are Part of the Tax and Estate Plan
This is why beneficiary designations are not an administrative detail. They are part of the tax and estate plan. A poorly coordinated beneficiary designation can change who recognizes the deferred income, how quickly it must be recognized, and how much flexibility the family has after death. An executor may sometimes be able to mitigate the damage, but that is very different from having the account properly structured before death.
Generational Wealth Planning Should Look Beyond One Taxpayer
For families concerned with generational wealth, the relevant question therefore should not be limited to how much tax one individual can defer during their lifetime. A more meaningful question is how much tax the family will ultimately pay on the same pool of wealth, who will pay it, and when that income will be forced onto their tax returns. The retirement account may survive the original owner’s death, but the deferred tax obligation generally survives with it.
I think these H3s are strong because they improve scanability without making the section feel chopped up. They also introduce useful long-tail phrases around inherited 401(k)s, beneficiary designations, the 10-year rule, estate beneficiaries, and IRA liquidation.
Not Every Dollar Is Equal When It Is Inherited
This is also why the composition of an estate can matter as much as its total value. A $500,000 traditional retirement account, a $500,000 Roth account, and a $500,000 taxable brokerage account do not necessarily represent the same after-tax inheritance even though each account statement displays the same number.
Traditional retirement assets generally carry deferred ordinary income. Roth assets can have substantially different income tax characteristics when distribution requirements are satisfied. Appreciated taxable investments may receive different basis treatment at death under current law. Real estate and business interests introduce still another set of tax and planning considerations.
For someone who expects to consume most of their assets during retirement, these differences may be relatively unimportant. For someone likely to leave substantial wealth to children, grandchildren, charities, or other beneficiaries, the characteristics of the assets being transferred should become part of the planning process well before death.
The estate planning question should therefore be broader than how much money beneficiaries will receive. It should include what type of property they will receive, what tax attributes accompany that property, and whether another allocation of assets could better accomplish the family’s objectives.
Sometimes Paying Tax Earlier Can Produce a Better Family Outcome
Taxpayers understandably dislike voluntarily recognizing income when they have the option to defer it. In many circumstances, continuing the deferral is entirely rational. There are also situations in which an obsessive focus on minimizing the current year’s income tax can produce a worse long-term result.
Imagine a retired parent who can recognize additional traditional retirement income at relatively moderate tax rates but refuses to take distributions or make Roth conversions because doing so would increase the current tax bill. The parent eventually dies with most of the traditional account intact. Their children inherit the account while already earning substantial incomes and ultimately recognize the deferred income at materially higher rates.
The parent’s tax returns may have been optimized in isolation. The family’s wealth may not have been.
That does not mean retirees should accelerate taxable income merely to reduce a hypothetical future tax bill for their children. Future tax law, beneficiary income, investment returns, longevity, and spending needs are all uncertain. It means the beneficiaries’ expected tax circumstances should at least enter the analysis when an account is clearly likely to become an inherited asset.
This is the distinction between annual tax preparation and long-term tax planning. The lowest possible tax liability this year is not automatically the lowest lifetime tax liability, and the lowest lifetime tax liability for one individual is not automatically the best after-tax result for a family trying to transfer wealth across generations.
Does the Employer Match Make a 401(k) Worth It?
Any criticism of 401(k) planning should also acknowledge one of the strongest reasons many employees should participate in their employer’s plan. A matching contribution can substantially change the economics of the decision. If an employer contributes additional compensation when an employee makes a qualifying contribution, declining to participate can mean walking away from a meaningful portion of the employee’s compensation package.
Contributing enough to capture a valuable employer match is a fundamentally different decision from determining where the next dollar should go after the full match has been received.
Once the match has been captured, the analysis can become more nuanced. Additional traditional contributions may still make sense, particularly for someone currently facing a high marginal tax rate. Another employee may benefit more from Roth contributions, an HSA, taxable investments, additional liquidity, or some combination of those options. The existence of a good employer match should influence the decision, but it does not answer every subsequent asset-allocation and tax-planning question.
401(k) Fees and Investment Options Can Change the Answer
The tax treatment of a 401(k) often receives so much attention that the quality of the underlying plan is treated as secondary. Employer plans, however, vary considerably. Some provide extremely inexpensive institutional funds, broad diversification, sensible default investments, and low administrative costs. Others contain more expensive investment options or relatively limited menus.
A tax deduction does not automatically compensate for an unnecessarily expensive plan, particularly when higher investment expenses compound over several decades. Conversely, access to excellent institutional investments at very low cost can make an employer plan more attractive than alternatives available to an individual investor.
The correct analysis therefore requires looking at the actual plan rather than evaluating the term “401(k)” in the abstract. Two employees with identical salaries and tax rates can rationally make different decisions because the quality of their respective employer plans is different.
Financial Incentives Are Worth Understanding
There are excellent financial advisors who integrate investment management with tax planning, retirement distributions, estate planning, and beneficiary strategy. There are also advisory models built primarily around accumulating and managing investment assets. Charging a fee based on assets under management is not inherently problematic, but the incentives created by any compensation structure should be understood.
Traditional tax deferral can naturally support asset accumulation. If a client can place $10,000 into a retirement account rather than paying current income tax and investing a smaller after-tax amount elsewhere, more capital remains invested. That can produce a larger future account balance, and it can eventually result in more assets available for an advisor to manage.
Those outcomes may align perfectly with what the client wants. They may not.
The important distinction is that maximizing assets under management is not the client’s financial objective. The client’s objective may be retirement income, financial independence, liquidity, business ownership, charitable giving, leaving wealth to children, or some combination of those goals. Investment accounts should be structured to serve those objectives rather than becoming the objective themselves.
This is why I would be cautious whenever the primary measure of financial success becomes the size of the portfolio. A larger account is certainly preferable to a smaller account when all other variables are equal, but all other variables rarely remain equal. Taxes, liquidity, control, beneficiary treatment, and the eventual use of the money matter as well.
So, Is a 401(k) Worth It?
When the Answer Becomes Less Obvious
For others, the answer becomes less obvious. Someone currently paying relatively low income tax rates may reasonably prefer additional Roth exposure. Someone who expects to retire well before conventional retirement age may need more accessible taxable assets. A household already holding substantial traditional retirement balances may decide that additional tax diversification is more valuable than continuing to concentrate wealth in deferred ordinary income. Someone whose primary objective is generational wealth may also need to consider the likely tax position of future beneficiaries.
The important point is not that one of these choices is universally superior. The important point is that the decision should be made deliberately rather than inherited from a generic rule of thumb.
The Right Question Changes With Your Stage of Life
A taxpayer who is still accumulating wealth should be asking what marginal tax rate is being avoided today, how valuable the employer match is, whether traditional and Roth options are available, how much wealth is already tax deferred, whether sufficient liquid assets exist outside retirement accounts, and what retirement income is reasonably expected to look like.
Someone approaching retirement should begin estimating future distributions, Social Security benefits, pensions, Medicare exposure, and possible low-income years before RMDs. Someone already in their 70s should be looking beyond the required minimum distribution and considering how remaining traditional assets fit into spending, charitable, and estate plans.
What Is This Dollar Supposed to Accomplish?
Those are all versions of the same underlying question. What is this particular dollar supposed to accomplish, and which financial structure gives it the best chance of accomplishing that objective?
For Business Owners, Your 401(k) Should Be Part of a Larger Tax Strategy
For business owners, retirement planning should not be separated from the rest of the financial picture. Your retirement accounts, business cash flow, entity structure, owner compensation, tax strategy, liquidity needs, succession planning, and estate goals all affect one another. A decision that looks attractive when viewed only as an investment can produce a very different result once the tax needs of the owner and the capital needs of the business are considered together.
At Corridor Consulting, we integrate retirement and wealth planning into our ongoing Client Advisory Services for business owners. Retirement contributions and distributions are evaluated alongside accounting, tax planning, profitability, owner compensation, cash flow, and long-term wealth goals rather than treated as isolated decisions made once a year.
The objective is not simply to maximize a retirement account or minimize this year’s tax liability. It is to make sure the wealth you are building inside and outside your business is structured around what you ultimately want that wealth to accomplish.
If you are a business owner and want your accounting, tax planning, and long-term wealth strategy working together, Corridor Consulting can help.
