Yes, you can have both a Roth 401(k) and a Roth IRA, and they work independently of each other

A Roth 401(k) is a workplace retirement plan your employer offers. A Roth IRA is an individual account you open on your own. The IRS treats them as separate accounts with separate contribution limits, so having both does not disqualify you from either one. You can contribute the maximum to each in the same year.

The main catch is income: your income determines whether you can contribute to a Roth IRA at all, but a Roth 401(k) has no income limit. If your income is too high for a Roth IRA, you can still use a Roth 401(k) through your employer. If your employer offers a Roth 401(k) option and your income is below the Roth IRA limit, you can fund both.

Key Takeaways

  • Roth 401(k) and Roth IRA contribution limits are separate, so you can max out both in the same year without one affecting the other.
  • Roth IRA contributions are limited by income; if you earn too much, you cannot contribute to a Roth IRA but can still use a Roth 401(k).
  • Roth 401(k) has no income limit, so high earners can use it even if they are blocked from a Roth IRA.
  • Both accounts grow tax-free and allow tax-free withdrawals in retirement, but the rules for withdrawing money before retirement differ between them.

How the contribution limits work when you have both

For 2024, the Roth 401(k) limit is $23,500 per year (or $31,000 if you are 50 or older). The Roth IRA limit is $7,000 per year (or $8,000 if you are 50 or older). These are completely separate buckets. Contributing $10,000 to your Roth 401(k) does not reduce how much you can put into your Roth IRA.

The only connection between them is if you have a traditional 401(k) and a Roth 401(k) at the same employer. Those two versions of the same plan share the $23,500 limit. So if you contribute $15,000 to a traditional 401(k), you can only add $8,500 to a Roth 401(k) at that same employer. But a Roth IRA is entirely separate and does not count toward that limit.

Income limits: where Roth IRA restrictions apply

Your income determines whether you can contribute to a Roth IRA. For 2024, if you file as single, you cannot contribute if your modified adjusted gross income (MAGI) is $161,000 or more. If you are married filing jointly, the limit is $240,000. These thresholds change each year.

A Roth 401(k) has no income limit. Even if you earn $500,000 per year and cannot touch a Roth IRA, your employer's Roth 401(k) is open to you. This is one reason high earners often rely on Roth 401(k)s — it is their only way to make new Roth contributions.

Tax treatment and withdrawal rules differ between the two accounts

Both accounts let your money grow tax-free and allow you to withdraw it tax-free in retirement. But the rules for pulling money out early are different. With a Roth IRA, you can withdraw your contributions (the money you put in) at any time, tax-free and penalty-free. Earnings (the growth) are locked until age 59½ unless you meet a narrow exception.

With a Roth 401(k), you cannot separate contributions from earnings. Any withdrawal before age 59½ is treated as a withdrawal of both, and the earnings portion is taxed and penalized unless you meet an exception. This makes a Roth IRA more flexible if you think you might need access to your money before retirement.

Required minimum distributions: another key difference

At age 73, you must start taking required minimum distributions (RMDs) from a Roth 401(k). You do not have to take RMDs from a Roth IRA during your lifetime — you can leave it untouched and pass it to heirs. If you want to avoid RMDs, you can roll a Roth 401(k) into a Roth IRA after you leave your job, which eliminates the RMD requirement.

This is a major reason some people with both accounts prioritize funding the Roth IRA first: it offers more control over when you take money out, and you can leave it to grow indefinitely if you do not need it.

Which one should you fund first if you have limited money

If you cannot max out both, most people fund the Roth 401(k) first if their employer matches contributions. An employer match is assistance programs and does not happen with a Roth IRA. After capturing the match, many people then fund the Roth IRA up to its limit, because of the flexibility on early withdrawals and the absence of RMDs.

If your employer does not match, the choice depends on your situation. A Roth IRA offers more flexibility and lower fees (you control the investments). A Roth 401(k) offers higher contribution limits and no income restrictions. If you earn above the Roth IRA income limit, the 401(k) is your only option for new Roth money.

What happens if you change jobs

When you leave a job, you can roll your Roth 401(k) balance into a Roth IRA. This move is tax-free and penalty-free as long as you do a direct rollover (the money goes straight from the plan to the IRA, not to you first). Rolling over gives you the Roth IRA's advantages: no RMDs during your lifetime, more investment choices, and the ability to withdraw contributions anytime.

You do not have to roll it over. You can leave it in your former employer's plan or roll it to your new employer's plan if they accept rollovers. But rolling to a Roth IRA is often the simplest option once you are no longer employed there.

Frequently Asked Questions

Does contributing to a Roth 401(k) reduce how much I can put in a Roth IRA?

No. The Roth 401(k) limit and Roth IRA limit are separate. You can max out both in the same year. The only limit that connects them is if you have both a traditional and Roth version of the same employer's 401(k) plan — those two share one limit.

Can I contribute to a Roth 401(k) if my income is too high for a Roth IRA?

Yes. Roth 401(k)s have no income limit. If you earn too much to contribute to a Roth IRA, a Roth 401(k) through your employer is your only way to make new Roth contributions. This is a major advantage for high earners.

Should I roll my Roth 401(k) into a Roth IRA when I leave my job?

Rolling over is often a good move because it eliminates required minimum distributions, gives you more investment choices, and typically costs less in fees. But you can also leave it in your former employer's plan or roll it to a new employer's plan. A direct rollover is always tax-free.

Can I withdraw money from a Roth 401(k) before retirement without penalty?

Withdrawals before age 59½ are subject to income tax and a 10% penalty on the earnings portion, unless you meet a narrow exception like disability or a may have access to hardship. A Roth IRA is more flexible — you can withdraw contributions anytime penalty-free, though earnings are locked until 59½.
