Yes, you can have both a Roth IRA and a 401(k) at the same time

You are allowed to contribute to a Roth IRA and a 401(k) in the same year. The IRS does not prevent you from holding both accounts. However, your ability to contribute the maximum to a Roth IRA depends on how much money you earn, and that income limit is separate from your 401(k) contributions. Your 401(k) contributions do not reduce the income limit for a Roth IRA, but your income itself does.

The real constraint is your own cash flow. You have limited dollars to save each year, and both accounts have annual contribution limits. A 401(k) limit and a Roth IRA limit are separate, but the money in your bank account is not. If you max out your 401(k), you may not have funds left to also max out a Roth IRA.

Key Takeaways

  • You can contribute to both a Roth IRA and a 401(k) in the same tax year without violating IRS rules.
  • Your Roth IRA contribution limit phases out based on your income, not on how much you put into your 401(k).
  • If your income exceeds the Roth IRA phase-out range, you cannot contribute to a Roth IRA directly, but you may still contribute to your 401(k).
  • The decision to fund both accounts depends on your income, your employer match, and how much you can afford to save.

How income limits work for Roth IRA contributions when you have a 401(k)

Your 401(k) contributions do not count toward the income limit that determines whether you can contribute to a Roth IRA. The IRS looks at your modified adjusted gross income (MAGI) to decide if you can fund a Roth IRA. Your MAGI is calculated before your 401(k) contribution is subtracted, so the 401(k) does not help you stay under the Roth income limit.

The Roth IRA income phase-out ranges vary by filing status and change each year. For 2024, if you file as single, the range begins at $146,000 and phases out completely at $161,000. If you are married filing jointly, it begins at $230,000 and phases out at $240,000. These numbers are set by the IRS and explore regardless of whether you have a 401(k).

If your income falls within the phase-out range, you can contribute a reduced amount to a Roth IRA. If your income exceeds the upper limit, you cannot contribute to a Roth IRA directly. In that case, some people use a strategy called a backdoor Roth, which involves contributing to a traditional IRA and then converting it to a Roth, but that has its own rules and tax consequences.

When it makes sense to fund both accounts

If your employer offers a 401(k) match, you should usually contribute enough to capture the full match before prioritizing a Roth IRA. An employer match is information programs and an when ready return on your contribution. After you have claimed the full match, you can decide whether to contribute more to your 401(k) or to open and fund a Roth IRA.

A Roth IRA can be attractive because withdrawals in retirement are tax-free, and you have more control over the investments than you might in a 401(k). If you are early in your career and expect your income to rise significantly, a Roth IRA locks in today's tax rate on those contributions. A 401(k) offers an when ready tax deduction, which lowers your taxable income this year.

The choice between funding a 401(k) beyond the match or a Roth IRA depends on your tax bracket now versus your expected tax bracket in retirement, how much you can afford to save, and whether you prefer the investment options in your 401(k) or the flexibility of a Roth IRA. There is no single right answer for everyone.

Contribution limits when you have both accounts

For 2024, you can contribute up to $23,500 to a 401(k) and up to $7,000 to a Roth IRA in the same year (or $8,000 if you are age 50 or older for the Roth). These limits are separate, meaning the IRS allows you to contribute the full amount to each account if you have the income and cash flow to do so.

However, if you have multiple 401(k)s or multiple IRAs, the limits work differently. All your traditional IRAs are treated as one account for contribution purposes, and all your 401(k)s are treated as one account. If you have a traditional IRA and a Roth IRA, each has its own $7,000 limit, but you cannot contribute $7,000 to each in the same year — the combined limit across all IRAs is $7,000.

The 401(k) limit and the IRA limit do not overlap. You can contribute $23,500 to your 401(k) and $7,000 to a Roth IRA in the same year without exceeding either limit. The constraint is whether you have enough income and savings to fund both.

What happens if you exceed the Roth IRA income limit

If your income exceeds the Roth IRA phase-out range, you cannot contribute directly to a Roth IRA. You can still contribute to your 401(k) with no income limit. You can also contribute to a traditional IRA, but if you are covered by a 401(k) at work, the tax deduction for traditional IRA contributions phases out based on income as well.

Some higher-income earners use a backdoor Roth strategy: they contribute to a traditional IRA (which has no income limit) and then convert it to a Roth IRA. This works, but it has tax implications if you have other traditional IRA balances. The IRS applies a pro-rata rule that can create a tax bill in the year you convert. You should understand this rule before attempting a backdoor Roth.

If you are above the Roth income limit and do not want to deal with a backdoor Roth, focusing on maxing out your 401(k) is a straightforward path to tax-advantaged retirement savings.

Tax treatment differs between the two accounts

A 401(k) contribution reduces your taxable income in the year you make it. If you contribute $10,000 to your 401(k), your taxable income drops by $10,000, which lowers your tax bill that year. When you withdraw money in retirement, those withdrawals are taxed as ordinary income.

A Roth IRA contribution does not reduce your taxable income this year. You contribute with after-tax dollars. In retirement, you withdraw the money tax-free. This makes a Roth IRA valuable if you expect to be in a higher tax bracket later or if you want tax-free growth over decades.

Having both accounts gives you tax diversification in retirement. You can have some money in a traditional 401(k) that you pay tax on when you withdraw it, and some money in a Roth IRA that comes out tax-free. This flexibility can help you manage your tax bill in any given year of retirement.

Required minimum distributions and Roth IRAs

At age 73, you must begin taking required minimum distributions (RMDs) from your 401(k). The amount is calculated based on your age and account balance, and you must withdraw at least that amount each year or face a penalty. This applies to traditional 401(k)s and traditional IRAs.

A Roth IRA does not require you to take distributions during your lifetime. You can leave the money in the account to grow tax-free for as long as you live. This makes a Roth IRA useful if you do not need the money in retirement and want to pass it to heirs tax-free. Your heirs will have to withdraw the money, but the growth inside the Roth is never taxed.

If you have both accounts, you can use your Roth IRA to cover living expenses in early retirement and delay withdrawals from your 401(k) to reduce your RMD later. This is one strategic reason some people prioritize funding a Roth IRA alongside a 401(k).

Frequently Asked Questions

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

No. Your 401(k) contribution does not lower your income for the purpose of the Roth IRA income limit. The IRS calculates your modified adjusted gross income before subtracting your 401(k) contribution. If your income is too high for a Roth IRA, contributing more to your 401(k) will not change that.

Can I contribute to a Roth IRA if my employer does not offer a 401(k)?

Yes. If you have no 401(k) at work, your ability to contribute to a Roth IRA depends only on your income and filing status. You can open a Roth IRA on your own through a bank or brokerage and contribute up to $7,000 per year (or $8,000 if you are 50 or older) as long as your income is below the phase-out limit.

Should I max out my 401(k) or my Roth IRA first?

If your employer offers a match, contribute enough to your 401(k) to capture the full match first. After that, many people prioritize a Roth IRA because of the tax-free withdrawals and flexibility. Once you have maxed the Roth, you can contribute more to your 401(k) if you have the cash flow. Your personal situation determines the best order.

What is a backdoor Roth, and do I need one?

A backdoor Roth is a strategy where you contribute to a traditional IRA and then convert it to a Roth IRA, allowing you to fund a Roth even if your income exceeds the limit. You need one only if your income is above the Roth phase-out range and you want Roth savings. Be aware of the pro-rata rule, which can create a tax bill if you have other traditional IRA balances.

Can I withdraw from both accounts in retirement without penalty?

From a 401(k), you can withdraw anytime after age 59½ without penalty. From a Roth IRA, you can withdraw your contributions anytime tax-free and penalty-free. You can withdraw earnings tax-free and penalty-free after age 59½ if the account has been open for at least five years. The rules are different, so understand your account type before you withdraw.
