Navigating retirement savings can seem complex, but understanding the tools available is crucial for long-term financial security. The 401(k) plan is one of the most powerful tools offered by many employers in the United States. Named after the relevant section of the Internal Revenue Code, these employer-sponsored plans provide significant tax advantages designed to encourage workers to save for retirement.

What is a 401(k) Plan?

The Internal Revenue Service (IRS) defines a 401(k) as a feature within a qualified profit-sharing plan, stock bonus plan, pre-ERISA money purchase pension, or rural cooperative plan. More simply, it’s a type of defined contribution retirement plan sponsored by an employer.

In a defined contribution plan, the focus is on the contributions made to an employee’s individual account. The ultimate retirement benefit depends on:

• Total contributions (from employee and potentially employer)
• Investment gains or losses
• Fees

This differs from a traditional defined benefit pension plan, which promises a specific monthly income in retirement based on factors like salary and years of service.

The core feature of a 401(k) is that it allows employees to defer a portion of their salary into the plan account. These employee contributions are often referred to as “elective deferrals.” Depending on the plan’s design, these contributions can be made on a pre-tax basis (Traditional 401(k)) or an after-tax basis (Roth 401(k)).

Many employers also choose to contribute to employee accounts, often through matching contributions based on the employee’s own deferrals. The primary purpose is to provide employees with a tax-advantaged way to accumulate savings for their retirement years.

Key Tax Advantage: Reduce Your Tax Bill Today

One of the most immediate benefits of participating in a Traditional 401(k) plan is the potential to lower current income taxes.

How Pre-Tax Contributions Work

When an employee contributes to a Traditional 401(k), the designated amount is deducted from their gross pay before federal income taxes (and typically state and local income taxes) are calculated and withheld. These deferred wages are generally not reported as taxable income on the employee’s Form 1040 for that year.

Immediate Tax Savings

The direct consequence of this pre-tax deduction is a reduction in the employee’s current taxable income. Lower taxable income translates directly into paying less income tax for the year the contribution is made. The magnitude of this immediate tax saving is greater for individuals in higher tax brackets, as each dollar contributed avoids taxation at that higher marginal rate.

It’s important to note that while these contributions escape income tax at the time of deferral, they are still included as wages subject to Social Security and Medicare taxes (FICA).

Example: Seeing the Savings

Consider an employee earning $50,000 annually who decides to contribute $5,000 (10% of salary) to their Traditional 401(k). For federal income tax purposes, their taxable income is reduced to $45,000. If this employee falls into the 12% federal income tax bracket, this $5,000 contribution results in $600 less federal income tax owed for that specific year.

Important Distinction

While the effect is similar to a tax deduction, pre-tax 401(k) contributions operate differently. They are not claimed as a separate deduction itemized on Form 1040. Instead, the reduction in taxable income happens automatically through the employer’s payroll system. The lower amount of taxable wages is then reported in Box 1 of the employee’s Form W-2.

This structure, combining automatic payroll deductions with immediate tax relief, leverages behavioral principles. The ‘out of sight, out of mind’ nature of automatic saving removes the need for active decision-making each pay period, overcoming potential procrastination or lack of discipline. Simultaneously, the noticeable reduction in current taxes provides positive reinforcement, making the long-term goal of retirement saving feel more tangible.

The fundamental value proposition of the Traditional 401(k) rests on the concept of tax rate arbitrage over an individual’s lifetime. The expectation is that the participant’s marginal income tax rate will be lower during their retirement years (when withdrawals are made and taxed) than during their peak earning years (when contributions are made and taxes are saved). The difference between the tax rate avoided at contribution and the tax rate paid at withdrawal represents the net tax advantage achieved through this deferral strategy.

Key Tax Advantage: Tax-Deferred Investment Growth

Beyond the initial tax break on contributions for Traditional 401(k)s, a powerful, long-term tax advantage shared by both Traditional and Roth 401(k) plans is tax-deferred growth.

The Power of Tax Deferral

Within the shelter of a 401(k) account, investment earnings – such as dividends paid by stocks, interest earned on bonds or cash, and capital gains realized from selling investments at a profit – are not subject to federal (and usually state) income tax on an annual basis. This tax treatment continues as long as the funds remain within the plan.

Contrast with Taxable Accounts

This stands in stark contrast to investments held in a standard, taxable brokerage account. In a taxable account, investors typically owe taxes each year on any dividends or interest received. Furthermore, when investments are sold for a profit (realized capital gains), those gains are also subject to capital gains tax in that year. This annual “tax drag” reduces the net return and leaves less capital available for reinvestment.

Compounding Without the Tax Drag

Tax deferral allows the entire investment return – the original contributions plus the full, untaxed earnings – to remain invested and work towards generating potential future earnings. This phenomenon, known as compounding, is significantly amplified when taxes are not siphoned off annually. Over many years or decades, this uninterrupted compounding can lead to substantially larger account balances compared to a taxable account holding the same investments and achieving the same gross returns.

Additionally, participants can typically buy and sell investments within their 401(k) account without triggering immediate tax consequences, allowing for portfolio adjustments without tax friction.

Eventual Taxation

It’s crucial to remember that “tax-deferred” does not mean “tax-free” for Traditional 401(k)s. The accumulated earnings, along with the original pre-tax contributions, will eventually be taxed as ordinary income upon withdrawal during retirement. For Roth 401(k)s, however, if withdrawal conditions are met, the earnings can be withdrawn entirely tax-free, as discussed in the next section.

While the immediate tax reduction from Traditional 401(k) contributions is often the most visible benefit, the impact of tax-deferred growth, although accumulating more quietly over time, can be far more substantial in building wealth over the long run. This “silent engine” of growth is arguably the most potent long-term tax advantage offered by 401(k) plans.

This powerful benefit of tax-deferred growth during the accumulation phase applies equally to both Traditional 401(k) and Roth 401(k) accounts. While the tax treatment of contributions (pre-tax vs. after-tax) and withdrawals (taxable vs. tax-free) differs significantly between the two types, the investment growth itself enjoys the same tax-sheltered environment within the plan.

Key Tax Advantage: Tax-Free Income in Retirement with a Roth 401(k)

While Traditional 401(k)s offer tax savings upfront, the Roth 401(k) option provides a compelling alternative with tax benefits realized at the back end – during retirement.

Paying Taxes Now for Tax-Free Withdrawals Later

Unlike Traditional contributions, contributions made to a Roth 401(k) account are designated as after-tax contributions. This means the money contributed is taken from the employee’s paycheck after federal, state, and local income taxes have already been withheld. Consequently, Roth contributions do not reduce the employee’s current taxable income, and there is no immediate tax deduction or saving in the year the contribution is made. The amount contributed is included in the employee’s gross income for that year.

The Big Payoff: Tax-Free Qualified Withdrawals

The primary allure of the Roth 401(k) emerges during retirement. If withdrawals from the Roth 401(k) account meet the criteria for a “qualified distribution,” then all the money withdrawn – both the original after-tax contributions and all the accumulated investment earnings – is completely free from federal (and typically state) income tax.

What Makes a Roth 401(k) Withdrawal “Qualified”?

To receive this favorable tax-free treatment on withdrawals, two main conditions must generally be satisfied:

1. The 5-Year Rule: The distribution must occur after the completion of a 5-taxable-year period. This period begins on the first day of the taxable year (January 1st) in which the participant first made any designated Roth contribution to the plan (or potentially to a predecessor plan if funds were rolled over). It’s crucial to note this clock starts with the very first contribution and applies to the entire Roth 401(k) account under that plan, not to each individual contribution.
2. Age or Event: The distribution must be made on or after the date the participant attains age 59½, OR on account of the participant becoming totally and permanently disabled, OR paid to a beneficiary or the participant’s estate on or after their death.

Roth Account Management

Due to the different tax treatment, employers are required to maintain a separate designated Roth account for each participant making Roth contributions. All contributions, gains, and losses must be tracked separately from any traditional, pre-tax contributions within the same plan.

Choosing the Roth 401(k) option can be viewed as a strategy to hedge against the uncertainty of future income tax rates. While the Traditional 401(k) provides its maximum benefit if tax rates are lower in retirement, the Roth 401(k) effectively locks in the tax rate prevailing at the time of contribution. This provides certainty regarding the tax treatment of retirement withdrawals and protects the savings from potential future tax increases.

Understanding the nuances of the 5-year rule is also critical for maximizing the Roth benefit. Because the 5-year holding period required for tax-free earnings withdrawal starts with the first contribution to the Roth account under the plan, delaying the initiation of Roth contributions effectively pushes back the date when accumulated earnings can be accessed tax-free, even if the participant has already reached age 59½. This suggests a potential strategic advantage in starting Roth 401(k) contributions early in one’s career, even if only with small amounts, simply to initiate the 5-year clock as soon as possible.

Get Extra Savings Help: The Retirement Savings Contributions Credit

Beyond the primary tax advantages of pre-tax contributions, tax-deferred growth, and tax-free Roth withdrawals, certain taxpayers may qualify for an additional benefit known as the Retirement Savings Contributions Credit, commonly called the Saver’s Credit.

What is the Saver’s Credit?

This is a non-refundable tax credit offered by the federal government specifically designed to encourage low-to-moderate-income individuals to save for retirement. Unlike a deduction, which reduces taxable income, a credit directly reduces the amount of tax owed, dollar-for-dollar, potentially down to zero (though it cannot result in a refund on its own as it is non-refundable).

Who is Eligible?

To qualify for the Saver’s Credit, a taxpayer must meet three basic criteria:

• Be age 18 or older
• Not be claimed as a dependent on another person’s tax return
• Not be a full-time student during the calendar year

Income Limits Apply

Eligibility for the credit, and the amount of the credit itself, is further restricted based on the taxpayer’s Adjusted Gross Income (AGI). AGI is gross income minus certain specific deductions. These income thresholds are adjusted annually by the IRS to account for inflation.

How Much is the Credit Worth?

The amount of the Saver’s Credit is calculated as a percentage (50%, 20%, or 10%) of the first $2,000 in qualifying retirement contributions made by an individual taxpayer, or the first $4,000 in contributions for those married filing jointly. The applicable percentage is determined by the taxpayer’s AGI and filing status, with lower incomes qualifying for higher credit percentages. The maximum possible credit is $1,000 for single filers ($2,000 contribution * 50%) and $2,000 for married couples filing jointly ($4,000 contribution * 50%).

Qualifying Contributions

Contributions made to various types of retirement accounts can qualify for the Saver’s Credit. This includes elective deferrals to both Traditional and Roth 401(k) plans, as well as contributions to Traditional or Roth IRAs, 403(b) plans, governmental 457(b) plans, SIMPLE IRA plans, Salary Reduction Simplified Employee Pension plans (SARSEPs), and Achieving a Better Life Experience (ABLE) accounts.

Note that contributions to workplace plans like 401(k)s generally must be made by December 31st of the tax year to count, while IRA contributions can typically be made up until the tax filing deadline (usually April 15th of the following year).

Table 1: Saver’s Credit AGI Limits and Credit Rates (Tax Year 2025 – For Returns Filed in 2026)

*Single, Married Filing Separately, Qualifying Surviving Spouse

For eligible taxpayers contributing to a Traditional 401(k), there’s a potential for layering tax benefits. The pre-tax contributions directly lower the taxpayer’s AGI. Since eligibility for the Saver’s Credit is determined by AGI, making these pre-tax contributions could potentially reduce AGI enough to either qualify the taxpayer for the credit when they otherwise wouldn’t, or push them into a lower AGI tier qualifying for a higher credit percentage (e.g., from 10% to 20%, or 20% to 50%).

This synergistic effect—getting both the upfront income reduction and a direct tax credit—makes Traditional 401(k) contributions particularly advantageous for individuals whose income falls near the Saver’s Credit eligibility thresholds.

The existence and structure of the Saver’s Credit underscore a clear public policy objective: to incentivize retirement savings specifically among lower- and middle-income households who might face greater financial pressures that impede saving. The credit phases out entirely at relatively modest income levels, meaning higher earners derive no direct benefit from it.

Furthermore, the credit percentage is intentionally tiered, offering the highest rate (50%) to those with the lowest adjusted gross incomes. This targeted approach demonstrates a deliberate governmental effort to broaden participation in retirement savings beyond traditionally higher-income brackets. (Legislative changes enacted in the SECURE 2.0 Act aim to further enhance this starting in 2027 by making the credit refundable and potentially deposited directly into the retirement account, although current rules apply for tax year 2025.)

Know Your Limits: How Much Can You Contribute?

To ensure the tax benefits of 401(k) plans are utilized appropriately and equitably, the IRS imposes annual limits on the amounts that can be contributed. Understanding these limits is essential for maximizing tax-advantaged savings potential.

Annual Employee Contribution Limit (Elective Deferrals)

There is a maximum amount that an employee can contribute from their own salary to their retirement plans each calendar year. This limit, often referred to as the 402(g) limit, applies to the combined total of elective deferrals made to all 401(k), 403(b), most governmental 457(b) plans, SARSEPs, and the federal Thrift Savings Plan that an individual might participate in.

For Tax Year 2025: The employee elective deferral limit is $23,500. This single limit encompasses the total of both Traditional (pre-tax) and Roth (after-tax) contributions made by the employee.

Catch-Up Contributions for Savers Age 50+

Recognizing that individuals may need or want to save more aggressively as they approach retirement, the tax code allows participants aged 50 and over by the end of the calendar year to make additional “catch-up” contributions above the standard elective deferral limit.

For Tax Year 2025: The standard catch-up contribution limit for 401(k), 403(b), and governmental 457 plans remains $7,500. This means individuals age 50 or over (but not ages 60-63, see below) can contribute a maximum of $23,500 (standard limit) + $7,500 (catch-up) = $31,000 in total employee deferrals in 2025.

Enhanced Catch-Up for Ages 60-63 (Starting 2025)

Effective January 1, 2025, due to provisions in the SECURE 2.0 Act of 2022, a higher catch-up contribution limit applies specifically to participants who attain age 60, 61, 62, or 63 during the calendar year. This enhanced catch-up is available if the employer’s plan adopts this feature.

For Tax Year 2025: The enhanced catch-up limit for individuals aged 60-63 is $11,250 (instead of the standard $7,500). Participants in this age group can therefore contribute up to $23,500 (standard limit) + $11,250 (enhanced catch-up) = $34,750 in total employee deferrals in 2025. This higher limit replaces the standard $7,500 catch-up for these specific ages; it is not additive.

Total Combined Limit (Annual Additions)

In addition to the limits on employee deferrals, there is an overall cap on the total amount of contributions that can be added to a participant’s account in a single year from all sources. This “annual additions” limit, governed by Internal Revenue Code Section 415(c), includes employee elective deferrals (both Traditional and Roth), employer matching contributions, and any other employer contributions, such as profit-sharing allocations.

For Tax Year 2025: The annual additions limit is the lesser of 100% of the participant’s compensation or $70,000. Catch-up contributions made by employees aged 50 and over are generally considered separate from this Section 415(c) limit, meaning the total amount deposited into an account (including employee catch-ups and employer contributions) can potentially exceed $70,000 for eligible individuals. For example, someone age 60 contributing the maximum employee deferral ($34,750) could still receive employer contributions, potentially bringing the total additions above $70,000, up to their compensation limit.

Why Limits Matter for Tax Benefits

Adhering to these contribution limits is essential because the valuable tax advantages associated with 401(k) plans – the upfront deduction for Traditional contributions, tax-deferred growth, potential tax credits, and tax-free withdrawals for Roth accounts – only apply to contributions made up to these legally defined maximums. Contributing as much as possible within these limits allows participants to maximize the scale and long-term impact of these tax benefits on their retirement accumulation.

Table 2: 401(k) Contribution Limits Summary (Tax Year 2025)

The annual adjustments to these contribution limits, driven by inflation indexing and legislative changes like the SECURE 2.0 Act, demonstrate how these limits function as policy levers. They reflect governmental responses to economic conditions (like inflation eroding purchasing power) and demographic shifts (such as an aging workforce needing enhanced savings opportunities).

The introduction of the standard catch-up provision acknowledged the need for later-career savings acceleration, while the new, higher catch-up specifically targeting ages 60-63 indicates a focused policy effort to enable maximum saving capacity in the years immediately preceding traditional retirement age. These adjustments act as tools intended to influence national savings behaviors and bolster retirement preparedness.

Furthermore, it’s critical for individuals participating in multiple retirement plans to understand that the employee elective deferral limit ($23,500 for 2025, plus applicable catch-ups) is an aggregate limit that applies across all their relevant plans combined. An individual cannot exceed their personal limit simply by contributing to, for instance, both a 401(k) at one job and a 403(b) at another. This IRS rule necessitates careful tracking and coordination by the participant to avoid excess deferrals, which can lead to tax complications.

Taking Money Out: Tax Rules for 401(k) Withdrawals

The tax advantages enjoyed during the contribution and growth phases of a 401(k) are balanced by specific tax rules governing withdrawals, particularly concerning timing and the type of account (Traditional vs. Roth).

How Withdrawals Are Taxed in Retirement

Traditional 401(k): When funds are withdrawn from a Traditional 401(k) in retirement, both the original pre-tax contributions and all the accumulated investment earnings are treated as ordinary taxable income. The withdrawals are added to other income received in that year and taxed at the individual’s prevailing federal and state income tax rates.

Roth 401(k): For Roth 401(k) accounts, withdrawals that meet the criteria for a “qualified distribution” (generally, satisfying the 5-year holding period rule and occurring after age 59½, disability, or death) are completely tax-free at the federal level (and usually state level). If a withdrawal from a Roth 401(k) is not qualified, the portion representing the original after-tax contributions is still returned tax-free, but the portion representing investment earnings is typically subject to ordinary income tax and potentially the early withdrawal penalty.

The 10% Early Withdrawal Penalty

To discourage the use of retirement funds for non-retirement purposes, the IRS generally imposes an additional 10% tax penalty on distributions taken from 401(k) plans (both Traditional and Roth) before the participant reaches age 59½. This penalty is applied in addition to any regular income tax due on the withdrawal. For Roth 401(k)s, the penalty (if applicable) generally applies only to the taxable earnings portion of an early, non-qualified withdrawal.

Common Exceptions to the Early Withdrawal Penalty

The tax code provides several exceptions where the 10% additional tax does not apply, although regular income tax might still be owed on the taxable portion of the distribution. Some common exceptions include distributions made:

• Upon the participant’s death (distributions to a beneficiary)
• Due to the participant’s total and permanent disability
• After separation from service with the employer sponsoring the plan, if the separation occurred during or after the year the participant reached age 55 (often called the “Rule of 55”)
• To pay for unreimbursed medical expenses exceeding a certain threshold (percentage of AGI)
• As part of a series of substantially equal periodic payments (SEPPs)
• To satisfy an IRS levy on the plan
• As qualified reservist distributions
• As qualified disaster distributions
• For qualified birth or adoption expenses (up to certain limits)
• In certain cases, for payments necessary to prevent eviction from a principal residence or foreclosure on a mortgage for that residence
• Emergency withdrawals up to $1,000 if permitted by the plan

Taxpayers claiming an exception typically need to file IRS Form 5329, Additional Taxes on Qualified Plans (including IRAs) and Other Tax-Favored Accounts. The instructions for Form 5329 provide a comprehensive list and details on qualifying for these exceptions.

Required Minimum Distributions (RMDs)

Because Traditional 401(k) contributions and earnings have not yet been taxed, the government mandates that withdrawals must begin at a certain point to ensure taxes are eventually collected. These are known as Required Minimum Distributions (RMDs).

Current RMD Age: Generally, participants must begin taking RMDs from their Traditional 401(k) accounts starting in the year they reach age 73. (This age threshold has been subject to legislative changes; prior rules involved age 72 or 70½ depending on birth year).

Still Working Exception: An important exception exists: if a participant is still employed by the company sponsoring the 401(k) plan when they reach RMD age, and they are not a 5% owner of the company, they can typically delay taking RMDs from that specific employer’s plan until they actually retire. This exception does not apply to IRAs or 401(k) plans from previous employers.

Penalty for Missed RMDs: Failing to withdraw the full RMD amount by the annual deadline can result in a substantial excise tax penalty. Currently, the penalty is 25% of the amount that should have been withdrawn but wasn’t. This penalty can potentially be reduced to 10% if the shortfall is corrected in a timely manner.

Roth 401(k) RMDs: Historically, Roth 401(k) accounts were subject to lifetime RMDs, similar to Traditional 401(k)s. However, a significant change introduced by the SECURE 2.0 Act eliminated lifetime RMDs for Roth 401(k) accounts, effective starting in the 2024 tax year. This aligns their treatment with Roth IRAs, which have never been subject to lifetime RMDs for the original owner. (Note: RMDs may still apply to beneficiaries inheriting Roth accounts).

The structure of withdrawal rules, particularly the 10% early withdrawal penalty and the RMD penalty for failing to take required distributions from Traditional accounts, serves as a strong enforcement mechanism for underlying policy goals. These penalties act as deterrents, reinforcing the intended purpose of 401(k) plans as vehicles specifically for retirement income, rather than general savings accounts.

The RMD rules, in particular, ensure that the tax deferral granted to Traditional accounts does not continue indefinitely, eventually forcing distributions and the collection of income tax revenue. The specific exceptions carved out for the early withdrawal penalty also reflect policy decisions about circumstances deemed acceptable for accessing these funds before retirement age, such as significant hardship or disability.

The recent elimination of lifetime RMDs for Roth 401(k)s significantly enhances the attractiveness of the Roth option, especially from the perspectives of retirement income flexibility and estate planning. Unlike Traditional 401(k) owners who are compelled to begin taxable withdrawals at age 73 regardless of their actual income needs, Roth 401(k) owners now face no such lifetime requirement.

This allows Roth funds the potential to continue growing tax-free for an extended period, gives retirees greater control over the timing and amount of their taxable income streams (which can help manage overall tax liability or taxes on Social Security benefits), and makes Roth accounts a more efficient vehicle for transferring wealth to beneficiaries, who will eventually owe taxes on inherited Traditional accounts but not typically on inherited Roth accounts if rules are followed.

Traditional 401(k) vs. Roth 401(k): A Tax Perspective

Many employer-sponsored 401(k) plans now offer employees the choice between making Traditional (pre-tax) contributions, Roth (after-tax) contributions, or a combination of both. The decision hinges primarily on how an individual wants to handle the taxation of their retirement savings.

Comparing Tax Treatment Throughout the Lifecycle

The core difference lies in the timing of taxation:

Contributions: Traditional 401(k) contributions are made with pre-tax dollars, meaning they reduce your taxable income in the year you contribute. Roth 401(k) contributions are made with after-tax dollars, offering no upfront tax reduction.

Investment Growth: Both Traditional and Roth 401(k) accounts benefit from tax-deferred growth. Investment earnings accumulate within the account without being taxed annually.

Qualified Withdrawals in Retirement: This is where the treatments diverge significantly. Withdrawals from a Traditional 401(k) (both contributions and earnings) are taxed as ordinary income. Qualified withdrawals from a Roth 401(k) (both contributions and earnings) are completely tax-free.

Choosing Based on Your Tax Outlook

The optimal choice between Traditional and Roth often depends on an individual’s assessment of their current income tax rate versus their anticipated tax rate during retirement:

• If you expect to be in a lower tax bracket in retirement than you are currently, the Traditional 401(k) may be more advantageous. You receive the tax break now at your higher rate and pay taxes later at the anticipated lower rate.
• If you expect to be in a higher tax bracket in retirement (due to career growth, other income sources, or potential future tax law changes), the Roth 401(k) may be preferable. You pay taxes now at your current, potentially lower rate, and avoid paying taxes later at the anticipated higher rate.
• If you expect your tax rate to be similar in retirement to your current rate, the tax outcome might be roughly equivalent. In this scenario, other factors might influence the decision, such as the desire for tax diversification in retirement or a preference for the tax certainty offered by the Roth option.

Table 3: Side-by-Side Tax Comparison: Traditional vs. Roth 401(k)

When comparing contribution amounts, it’s useful to consider the impact on take-home pay and future spending power. A $100 pre-tax contribution to a Traditional 401(k) reduces current take-home pay by less than $100 because of the immediate tax savings (e.g., by $88 if in a 12% tax bracket). Conversely, a $100 after-tax contribution to a Roth 401(k) reduces take-home pay by the full $100.

However, looking ahead to retirement, that $100 Roth contribution (plus earnings) can be withdrawn tax-free. To get $100 of after-tax spending money from the Traditional 401(k) in retirement, the participant would need to withdraw more than $100 pre-tax (e.g., $113.64 if their retirement tax bracket is 12%) to account for the taxes due upon withdrawal. Therefore, contributing the same dollar amount to a Roth 401(k) effectively secures a larger amount of future tax-free spending power compared to an identical dollar contribution to a Traditional 401(k), assuming the same contribution limits apply.

Given the uncertainty surrounding future tax rates and individual retirement income needs, employing a tax diversification strategy can be prudent. Contributing to both Traditional and Roth 401(k) accounts (if available) during one’s working years builds pools of assets with different tax characteristics.

In retirement, this provides valuable flexibility. Retirees can strategically choose which accounts to draw from each year – taxable withdrawals from Traditional accounts or tax-free withdrawals from Roth accounts – to potentially manage their overall annual tax liability, stay within desired tax brackets, or minimize the impact of withdrawals on the taxation of other income sources like Social Security benefits.
