Why a 401(k) Plan May Not Be Worth It

The 401(k) plan is a widely adopted retirement savings vehicle, enabling employees to contribute a portion of their salary directly from paychecks, often with an employer match, and benefit from tax-advantaged growth. Despite its prevalence, certain characteristics of the 401(k) structure may lead some individuals to question its value or suitability for their financial goals. An exploration of these characteristics can provide a clearer understanding of potential drawbacks.

Understanding Associated Costs

401(k) plans include associated costs that can erode investment returns. These costs typically fall into categories like administrative fees, investment management fees, and transaction fees. Administrative fees cover plan operations such as record-keeping and legal compliance, and can range from around $45 to $80 per participant annually. Some plans may also charge a monthly or annual fee for these administrative processes.

Investment management fees, often expressed as expense ratios, are charged by the mutual funds or other investment vehicles within the 401(k) plan. These ratios represent a percentage of the assets under management and can vary. Passively managed index funds often have lower expense ratios, typically under 0.50%, while actively managed funds can charge 0.5% to 1.0% or more. The average expense ratio paid by 401(k) participants was approximately 0.5% of plan assets as of 2021.

Even small percentages can have a compounding effect. For example, a 1% difference in annual fees could lead to a 28% reduction in a retirement balance over 35 years. On a $100,000 balance, a 0.25% annual expense ratio amounts to $250 per year, which accumulates over decades. These fees are usually deducted directly from the fund’s assets, reducing the net return to the investor.

Investment Option Constraints

A common limitation within 401(k) plans concerns the range of available investment options. Unlike a standard brokerage account that offers access to a vast universe of individual stocks, bonds, and other securities, 401(k) plans typically provide a curated and limited selection of investment vehicles. These usually consist of mutual funds, target-date funds, or other pooled investment options chosen by the plan administrator or employer.

The number of investment choices can vary widely, with some plans offering as few as 3-4 options, while others might provide more than 50. This restricted menu can prevent investors from implementing specific investment strategies or accessing certain asset classes not represented in the plan’s offerings. It can also limit the ability to achieve a desired level of diversification or risk exposure.

While mutual funds offered within 401(k)s often include a mix of index funds, large-cap, small-cap, international, and bond funds, the choices are ultimately determined by the plan sponsor. This can mean that even if a participant desires a particular low-cost index fund, it may not be available within their plan, forcing them to choose from higher-cost alternatives. The limited selection can be a drawback for investors who prefer greater control and flexibility over their portfolio composition.

Accessing Funds and Distribution Rules

Accessing funds held within a 401(k) plan is subject to specific rules and restrictions, primarily designed to encourage long-term savings for retirement. A 10% early withdrawal penalty applies to distributions taken before age 59½, in addition to regular income tax due on the withdrawn amount.

There are several exceptions to this 10% penalty, including distributions made due to:
Total and permanent disability
Death of the account owner
Substantially equal periodic payments (SEPPs)
Unreimbursed medical expenses exceeding 7.5% of adjusted gross income
Qualified higher education expenses
Certain distributions to qualified military reservists called to active duty
Separation from service during or after the year they turn 55 (or age 50 for certain public safety employees)
Qualified birth or adoption expenses (up to $5,000)
Certain financial emergencies (up to $1,000 per year)
Victims of domestic abuse (up to $10,000 or 50% of the account)

Participants are typically required to begin taking distributions from traditional 401(k) accounts once they reach a certain age, known as Required Minimum Distributions (RMDs). The SECURE Act 2.0 increased the age for RMDs. For individuals who turned 73 after December 31, 2022, the RMD age is 73. This age will further increase to 75 for those who turn 73 after December 31, 2032. These mandatory withdrawals can be a constraint for individuals who do not need the funds at that time, as they are compelled to withdraw taxable income even if it is not financially necessary.

Considerations for Tax Deferral

Traditional 401(k) plans operate on a tax-deferred basis: contributions are made with pre-tax dollars, reducing current taxable income. Investments grow without being subject to annual taxation on gains or dividends. However, all withdrawals in retirement are taxed as ordinary income. This tax treatment assumes an individual will be in a lower tax bracket during retirement than during their working years.

The uncertainty surrounding future tax rates poses a consideration. If an individual anticipates being in a higher tax bracket in retirement, or if overall tax rates increase in the future, the benefit of current tax deferral might be diminished. This could result in a higher overall tax burden than if the taxes had been paid upfront. For example, growth in tax-deferred accounts can accumulate to a substantial sum, which then becomes fully taxable upon withdrawal, potentially pushing retirees into higher tax brackets.

Some may find that paying taxes on contributions now, through options like a Roth 401(k) where qualified withdrawals are tax-free in retirement, offers more certainty regarding their future tax liability, especially if they expect tax rates to rise. The decision between pre-tax and after-tax contributions depends on an individual’s financial situation and their outlook on the future tax landscape.
