Most investors are familiar with 401(k) plans and IRAs, but not as many have heard about Roth accounts.

What Are Roth Accounts?

Roth accounts are a special type of retirement account that offer tax-free growth and tax-free withdrawals in retirement — and they are available in both 401(k) and IRA versions.

What sets them apart is that your employer must establish a Roth 401(k), while you can open your own personal Roth IRA. Which type of account is best for you depends on your income level, investment style and need for liquidity. Access is also an issue, as not all employers offer Roth 401(k) accounts.

For 2026, rules regarding contributions and income limitations for these accounts are slightly different than in 2025. Here’s a look at the rules, the limits and the strategy for determining whether a Roth 401(k) or a Roth IRA is a better match for you.

Key Differences Between a Roth IRA and a Roth 401(k)

Here’s a scannable comparison:

2026 Contribution Limits

• Roth 401(k): Much higher limit of $24,500 for under 50, $32,500 for those 50 and up
• Roth IRA: Lower limit of $7,500 for under 50, $8,600 for those 50 and up

Income Limits

• Roth 401(k): No income ceiling for employee Roth deferrals via an employer plan.
• Roth IRA: You must be under certain income thresholds to contribute directly.

Employer Match

Only available in the Roth 401(k) context, via employer plan.

Tax Benefits: Same Goal, Different Mechanics

Fundamentally, Roth IRAs and Roth 401(k) plans share the same basic tax structure. But the way they operate is different, resulting in different retirement tax benefits.

The Tax Similarities

• Contributions are made with after-tax dollars.
• You won’t receive an immediate tax break on contributions you make today.
• Qualified distributions are 100% tax-free in retirement.

The Main Tax Difference

• Thanks to the Secure 2.0 legislation signed into law in 2022, employers can now offer matches into the Roth side of an employee’s 401(k) plan. Prior to Secure 2.0, employers were required to deposit matching contributions into the pre-tax/traditional bucket.
• Note: If you do receive a matching contribution in your Roth bucket, you must pay income tax on that match amount in the year you receive it.

Investment Options: Freedom vs. Simplicity

In a nutshell, a Roth IRA offers more freedom, but it requires you to be in control. A Roth 401(k) can essentially be run on auto-pilot, but it limits your options. Here’s a breakdown of the differences:

• Roth IRA — offers more freedom:
  • You can buy a wide range of investments in a Roth IRA, from individual stocks and bonds to ETFs, mutual funds and REITs.
  • Best for: DIY investors who want total investment control and/or lower fees
• Roth 401(k) — offers simplicity:
  • Your investment options are limited to the menu of funds selected by your employer.
  • Best for: “Set it and forget it” investors

Withdrawal Rules and Penalties

When it comes to taking money out of your retirement account, the Roth IRA is the hands-down winner. As an employer-sponsored plan, the Roth 401(k) comes with a wide array of restrictions and potential penalties.

Roth IRA: The Winner for Flexibility

Withdrawals at Any Time

You can withdraw your contributions to a Roth IRA at any time, for any reason, without paying any taxes or penalties. This means you can use your Roth IRA as a home for your emergency fund, if so desired.

If you have an immediate need for funds, there are no restrictions on taking out your contributions. However, if you end up not needing emergency funds, your money can grow tax-deferred in the account and ultimately be withdrawn tax-free.

Taxes and Penalties

You will face taxes and penalties if you withdraw any of your Roth IRA earnings before age 59 1/2, subject to limited exceptions.

Once you reach age 59 1/2 and you’ve held a Roth IRA for at least five years, all distributions are tax- and penalty-free.

Roth 401(k): A More Restrictive Option:

You can’t generally withdraw money before age 59 1/2 from an employer-sponsored 401(k) plan, even a Roth 401(k), unless you take a 401(k) loan or claim a qualifying hardship.

When you withdraw money, the IRS requires that you use the pro-rata rule. What this means is that you can’t usually separate contributions from earnings. While the contribution portion of a distribution can come out tax-free, the earnings may be taxable if not in the form of a qualified distribution (i.e., before age 59 1/2 or within 5 years of opening a Roth account).

Required Minimum Distributions (RMDs)

Roth IRAs have never had a required minimum distribution, regardless of the account holder’s age. Roth 401(k) plans, however, have historically mandated RMDs. This all changed with the passage of the SECURE 2.0 Act. As of 2024, the IRS no longer requires RMDs for Roth 401(k) holders during their entire lifetimes.

The bottom line: As of 2024, both Roth IRAs and Roth 401(k) plans are equivalent in terms of RMD regulations. You can keep your money in either type of account as long as you’d like before passing it on to your heirs.

Which Is Better for Young Professionals?

For young professionals with access to an employer-sponsored Roth 401(k) plan, that’s often the best place to start. You should at least contribute up to the amount of your employer match percentage to maximize your returns.

Ultimately, there’s no right or wrong answer to whether a Roth IRA or a Roth 401(k) is the right choice for young professionals. The decision comes down to your own personal financial and tax situation, long-term goals and accessibility.

For example, if you earn $50,000 per year and your employer matches 50% of your contribution up to 5% of your income, try to put in at least $2,500 to your Roth 401(k). That way, your employer will kick in the maximum benefit of 50% of your contribution, or $1,250 in this case.

After that, you may consider switching your contributions to a Roth IRA. Since you won’t receive any additional matching from your employer, the personal Roth IRA now gives you greater flexibility. With the Roth IRA, you can withdraw your contributions tax- and penalty-free at any time, choose from a wider range of investments, and typically pay lower fees.

If you end up reaching the 2026 contribution limit of $7,500, then you can continue putting money into your Roth 401(k).

Can You Have Both?

As seen above, yes, you can contribute to both a Roth 401(k) and a Roth IRA in the same year. If you maxed out your contributions in 2026, you could sock away $24,500 into your Roth 401(k) and an additional $7,500 a Roth IRA. This gives you a potential contribution limit of $32,000 into your Roth accounts in 2026 — assuming you meet all other requirements, not counting your employer matching contributions.

How To Choose Between a Roth 401(k) and a Roth IRA

Here are some steps you can take to help you make the right decision between a Roth IRA and a Roth 401(k):

Step 1: Does your employer offer a retirement plan with a match?

• Yes ✅: Contribute to the Roth 401(k) first, at least to the limit of the employer match.
• No ❌: Move to Step 2.

Step 2: Do you have high-interest debt (e.g., credit cards)?

• Yes ✅: Consider contributing to your Roth 401(k) first, to the limit of your employer match. Then, use any excess funds to pay down high-interest debt before considering other contribution options.
• No ❌: Move to Step 3.

Step 3: Do you prioritize control over your investments and access to your funds?

• Yes ✅: Open a Roth IRA and contribute up to the limit.
• No ❌: Continue focusing on the Roth 401(k).

Step 4: Have you maxed out your Roth IRA — $7,500 for 2026 if you are under 50, $8,600 if 50 and over?

• Yes ✅: Go back and direct more to your Roth 401(k).
• No ❌: Continue with your Roth IRA until you reach your limit.

The bottom line: Focus on getting your maximum employer match in your Roth 401(k) first. Then, max out your Roth IRA contributions as much as possible to benefit from increased flexibility. If you still have additional funds to contribute, return to the 401(k) and sock away as much as possible.

Which To Choose — Roth 401(k) or Roth IRA?

There is no “one-size-fits-all” answer when it comes to choosing between a Roth IRA and a Roth 401(k) for 2026. The best answer for you individually comes down to whether you prioritize contribution space and an employer match — both of which favor the Roth 401(k) — or investment freedom and liquidity, in which case the Roth IRA might be a better option.

The good news is that both are solid options, and you can even choose to open both types of accounts, if you have access to them. Just bear in mind that rules and regulations for Roth accounts tend to change frequently, so keep an eye open for any updates that may change the equation for you, particularly when it comes to Roth withdrawal rules.

Good To Know

Check your employer’s plan document to see if a Roth 401(k) is even available to you. If so, search for information on the employer match (if any), investment options and fees.
