What Are the Benefits of a 401(k) Plan?

Benefits of 401(k)s

If you have access to a 401(k), it may be the centerpiece of your retirement savings plan. Here are some of the most notable 401(k) benefits.

Tax Perks

This is one of the primary reasons to invest in a 401(k). The tax benefits of a traditional 401(k) can help your money go further during your working years, and you won't owe taxes until you make withdrawals in retirement.

• Contributions reduce your taxable income. The money you put in is automatically taken out of your paycheck before you pay taxes on it. That reduces your taxable income for the year—and, in turn, your tax liability.
• Your money grows tax-free until withdrawal. A 401(k) is a tax-deferred retirement account. That means you won't pay taxes until you withdraw contributions or capital gains from the account.

Roth 401(k)s are also worth mentioning. These employer-backed retirement accounts are funded with after-tax dollars, which allows for tax-free withdrawals in retirement. The trade-off is that contributions are not tax-deferred.

Employer Match

Many employers offer a 401(k) match, which can provide free money for retirement. That may be a dollar-for-dollar match or a partial match, up to a certain point. For example, they might offer a 50% match up to 6% of an employee's salary. For 401(k)s managed by Fidelity Investments, the average employer 401(k) match is 4.8%.

Automatic Contributions

Contributions to a 401(k) are generally made through automatic payroll deductions. You specify how much you want to contribute, then that amount is withheld from your paycheck on a pretax basis and funneled directly into your 401(k).

You can choose your 401(k) investments yourself or allow your plan administrator to do it for you based on your expected retirement age. Most 401(k)s allow you to invest in mutual funds, index funds, exchange-traded funds (ETFs) and bonds.

Drawbacks of 401(k)s

There are also some important downsides of 401(k)s to consider. Being aware of them can help you plan ahead and prevent financial surprises down the road.

Withdrawal Taxes

Traditional 401(k) withdrawals made during retirement are taxed as ordinary income. How much you'll owe will depend on:

• The amount withdrawn
• Your tax bracket, which is determined by your income and tax filing status
• Your age at the time of the withdrawal

This can create a significant tax burden when you're no longer working—especially if a 401(k) is your primary source of retirement income. If you withdraw funds from a traditional 401(k) before age 59½, you'll likely owe a 10% early withdrawal penalty on top of taxes.

Roth 401(k)s work differently. You can withdraw contributions at any time tax-free, but if you're under 59½ and have had the account for less than five years, you'll be taxed on investment gains. You might also incur a 10% penalty.

Contribution Limits

In 2026, you can contribute up to $24,500 to a 401(k). Those who are 50 and older can put in an additional $8,000. If you're 60 to 63, you can kick in up to an extra $11,250 in "super catch-up" contributions.

Be aware that overfunding a 401(k) could lead to double taxation. Since contributions are limited, and withdrawals are taxable, your 401(k) might not be enough to fully fund your retirement.

Required Minimum Distributions

You must begin making annual withdrawals from your 401(k) at age 73. These are called required minimum distributions (RMDs). Failing to comply could result in a tax penalty of up to 25% of the amount not withdrawn. Your RMD amount will depend on:

• Your 401(k) balance at the end of the previous year and
• A life expectancy factor that's determined by the IRS

Should I Choose a 401(k) or an IRA?

You can open and fund an individual retirement account (IRA) yourself, apart from your employer. In 2026, you can contribute up to $7,500 (or $8,600 if you're 50 or older). There are two main types of IRAs:

• Traditional IRA: Contributions may be tax deductible, though you'll be taxed when you withdraw money. You can also expect a 10% early withdrawal penalty if you dip into the account before age 59½. RMDs apply.
• Roth IRA: Roth accounts are funded with after-tax dollars. That means you can withdraw your contributions at any time without triggering taxes or penalties. But to withdraw investment gains tax- and penalty-free, you'll need to be 59½ or older and have the account for five years or more.

When to Choose a 401(k)

Here are some situations where it might make sense to invest in a 401(k) over an IRA:

• You have an employer match. This could unlock free money for retirement. If this is an option, consider exhausting your match before investing in other accounts.
• You prefer hands-off investing. A 401(k) can be a set-it-and-forget-it retirement account that doesn't require much work on your part. You may be able to invest in target-date funds that automatically rebalance on their own.
• You want a tax break today. Traditional 401(k) contributions reduce your taxable income during your working years. That can be an attractive perk, though you'll owe taxes when you withdraw money in retirement. Roth 401(k) contributions are not tax-deductible, but you can enjoy tax-free withdrawals as a retiree.

When to Choose an IRA

There are some scenarios where you might opt for an IRA instead of a 401(k). That may be your best bet if:

• Your employer doesn't offer a 401(k). If you're self-employed or don't have access to a workplace retirement plan, an IRA can be a tax-efficient option.
• You want more investment options. Employer-sponsored 401(k)s can be limited. An IRA allows you to select your own broker and investments—instead of relying on your plan administrator's options. Your 401(k) may also have high fees.
• You want more control over your contributions. With an IRA, you can easily modify your contribution amount and make lump-sum contributions. However, 401(k) contributions must be coordinated through your employer.

Can I Have a 401(k) and an IRA?

Yes, you can have a 401(k) and IRA at the same time. This could be a great option if you want to:

• Diversify your retirement income sources
• Benefit from a Roth account
• Continue saving for retirement after maxing out your 401(k)
• Roll funds from an old 401(k) into a new IRA

The Bottom Line

If you're looking for a hands-off, tax-friendly way to save for retirement, investing in a 401(k) is a good strategy. That's especially true if you have access to an employer match at work. But you'll be taxed on withdrawals, so you'll want to plan ahead for that financial burden. There are also contribution limits, early withdrawal penalties, RMD requirements and potential 401(k) fees to consider. However, the 401(k) benefits might outweigh the drawbacks.
