Contributing to Both a Roth 401(k) and Roth IRA in the Same Year

By Felix Thorpe · Retirement Accounts Writer

Yes, you can contribute to both a Roth 401(k) and a Roth IRA in the same year, and they have separate contribution limits

A Roth 401(k) and a Roth IRA are two different accounts with two different annual contribution limits. The IRS treats them as separate buckets of money. You can max out one, max out the other, or contribute to both at whatever level works for your budget — as long as you have earned income to support the contributions.

The catch is income-based: your ability to contribute to a Roth IRA phases out at higher income levels, while a Roth 401(k) has no income limit. If you earn above a certain threshold, you might not be able to contribute to a Roth IRA at all, even though you can still use a Roth 401(k) through your employer.

The other constraint is practical: your Roth 401(k) contributions are limited by what your employer's plan allows, and not all employers offer a Roth 401(k) option. If yours does not, you can still contribute to a Roth IRA on your own.

Key Takeaways

  • Roth 401(k) and Roth IRA contribution limits are separate, so you can contribute the maximum to both in the same year if your income and employer plan allow it.
  • Roth IRA contributions phase out and eventually stop if your modified adjusted gross income exceeds IRS thresholds, which vary by filing status and change each year.
  • Roth 401(k) contributions have no income limit, making them an option for high earners who cannot contribute to a Roth IRA.
  • Your employer must offer a Roth 401(k) option for you to use one; not all plans include it.
  • Both accounts grow tax-free and allow tax-free withdrawals in retirement, but they have different withdrawal rules before age 59½.

How the contribution limits work side by side

For 2024, the Roth IRA contribution limit is $7,000 per year if you are under age 50, or $8,000 if you are 50 or older. These limits apply to all your IRAs combined — if you have a traditional IRA and a Roth IRA, your total contributions to both cannot exceed $7,000 (or $8,000 at 50+).

The Roth 401(k) limit is separate. For 2024, you can contribute up to $23,500 per year if you are under 50, or $31,000 if you are 50 or older. This limit applies only to your 401(k) accounts and does not reduce what you can put into a Roth IRA.

If you have both accounts, you could theoretically contribute $7,000 to a Roth IRA and $23,500 to a Roth 401(k) in the same year — a total of $30,500 — as long as your income supports it and your employer plan offers the Roth 401(k) option. The two accounts do not compete for the same annual limit.

Income limits for Roth IRA contributions

Your ability to contribute to a Roth IRA depends on your modified adjusted gross income (MAGI), which is usually your gross income with certain adjustments. The IRS sets income ranges where your contribution amount phases out, and these ranges change each year.

For 2024, if you file as single, your Roth IRA contribution begins to phase out at $146,000 MAGI and is completely blocked at $161,000. If you file as married filing jointly, the phase-out starts at $230,000 and ends at $240,000. If you are married filing separately, the limits are much lower — the phase-out begins at $0 and ends at $10,000.

A Roth 401(k) has no income limit. No matter how much you earn, you can contribute to a Roth 401(k) if your employer offers one. This makes it a valuable tool for high earners who want to save in a Roth account but cannot use a Roth IRA.

When your employer does not offer a Roth 401(k)

Not every employer plan includes a Roth 401(k) option. Some offer only a traditional 401(k), some offer both, and some offer neither. If your employer does not offer a Roth 401(k), you cannot create one on your own — it must come through an employer plan.

If this is your situation, you can still contribute to a Roth IRA separately, as long as your income is below the phase-out threshold. You might also explore a backdoor Roth conversion if your income is too high for a direct Roth IRA contribution, though that strategy involves converting a traditional IRA and has its own rules.

Check your employer's plan documents or ask your benefits administrator whether a Roth 401(k) option is available. The plan summary should list it clearly.

Withdrawal rules differ between the two accounts

Both Roth accounts allow tax-free withdrawals of earnings in retirement, but the rules for withdrawing money before age 59½ are different. Understanding this matters if you think you might need access to your money before retirement.

With a Roth IRA, you can withdraw your contributions (the money you put in) at any time, tax-free and penalty-free. You can only withdraw earnings before 59½ if you meet an exception, such as a first-time home purchase (up to $10,000 lifetime) or a may have access to disability. The account must also have been open for at least five tax years.

With a Roth 401(k), you cannot withdraw contributions or earnings before age 59½ without paying income tax and a 10% penalty, with limited exceptions. The Roth 401(k) does not have the same flexibility as a Roth IRA for early access to contributions. However, you can borrow from a Roth 401(k) if your plan allows it — something you cannot do with an IRA.

Required minimum distributions and account ownership

A Roth IRA has no required minimum distributions during your lifetime. You can leave the money in the account as long as you want and pass it to heirs tax-free. This makes it a powerful tool for long-term wealth building and estate planning.

A Roth 401(k) does require minimum distributions starting at age 73 (as of 2023, under the SECURE 2.0 Act). You must withdraw a calculated amount each year based on your age and account balance. If you do not need the money, this can be a drawback compared to a Roth IRA.

One workaround: some employers allow you to roll a Roth 401(k) into a Roth IRA after you leave the job. This would eliminate the required minimum distribution requirement, though the rollover must follow specific IRS rules to avoid tax consequences.

Tax treatment of contributions and growth

Both Roth accounts use after-tax dollars for contributions. You do not get a tax deduction when you contribute, but the money grows tax-free and comes out tax-free in retirement. This is the defining feature of any Roth account.

A Roth 401(k) contribution reduces your take-home pay immediately because it comes from your paycheck after taxes. A Roth IRA contribution also uses after-tax money, but you fund it separately from your paycheck, so the tax impact is less visible.

If you are in a lower tax bracket now and expect to be in a higher bracket in retirement, a Roth account makes sense for both. If you expect to be in a lower bracket in retirement, a traditional account might save you more in taxes overall. Contributing to both types of accounts can hedge against uncertainty about future tax rates.

Frequently Asked Questions

Does contributing to a Roth 401(k) reduce my Roth IRA contribution limit?

No. The two accounts have completely separate contribution limits. Money you put into a Roth 401(k) does not count against your Roth IRA limit, and vice versa. You can contribute the maximum to both in the same year if your income and employer plan allow it.

What happens if I exceed the income limit for a Roth IRA but have a Roth 401(k)?

You can still use the Roth 401(k) with no income limit. High earners often use a Roth 401(k) as their primary Roth savings vehicle when they earn too much for a Roth IRA. Some also use a backdoor Roth conversion strategy, though that involves converting a traditional IRA and has specific steps.

Can I withdraw my Roth 401(k) contributions early without penalty?

No, not like a Roth IRA. A Roth 401(k) treats contributions and earnings the same way — both are locked until age 59½ except in cases of disability, death, or other narrow exceptions. A Roth IRA lets you withdraw contributions anytime penalty-free, which is a major advantage if you might need early access.

Should I max out my Roth 401(k) before contributing to a Roth IRA?

That depends on your employer match and your tax situation. If your employer matches 401(k) contributions, contribute enough to get the full match first — that is assistance programs. Beyond that, many people prioritize the Roth IRA because of its flexibility and lower required minimum distributions, then use the Roth 401(k) for additional savings.

Can I roll a Roth 401(k) into a Roth IRA?

Yes, after you leave your job. A direct rollover from a Roth 401(k) to a Roth IRA is tax-free and penalty-free if done correctly. This can be useful because it eliminates the required minimum distribution requirement and gives you more flexibility over withdrawals. Check with your plan administrator about the rollover process.
