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

Yes, you can contribute to both a 401(k) and a Roth IRA in the same year

You are allowed to put money into a 401(k) at work and a Roth IRA in the same calendar year. The two accounts have separate contribution limits, so the money you put into one does not reduce how much you can put into the other. However, your ability to contribute to a Roth IRA depends on your income, and that income includes what you earn from your job — the same job that offers the 401(k).

The main constraint is not whether you can do both, but whether your income stays within the Roth IRA income limits while you are also funding a 401(k). If your income is too high, you cannot contribute to a Roth IRA at all, regardless of how much you put into your 401(k).

Key Takeaways

A 401(k) contribution does not reduce your Roth IRA contribution limit, because the two accounts track contributions separately.
Your income determines whether you can contribute to a Roth IRA, and that income includes your 401(k) salary, so a higher-paying job may push you over the income limit.
The 401(k) contribution limit and the Roth IRA contribution limit are set by the IRS each year and vary by age and account type.
Contributing to both accounts in the same year is a common strategy for people whose income falls within the Roth IRA range.

How the contribution limits work separately

The IRS sets a yearly limit on how much you can contribute to a 401(k) and a separate yearly limit on how much you can contribute to a Roth IRA. These limits do not interact with each other. If you contribute the maximum to your 401(k), you can still contribute the full amount to your Roth IRA, as long as your income qualifies you.

For example, if the 401(k) limit is $23,500 and the Roth IRA limit is $7,000, you could put $23,500 into your 401(k) and $7,000 into your Roth IRA in the same year. The $23,500 you contributed to the 401(k) does not count against your $7,000 Roth IRA limit.

The only limit that connects the two accounts is the income threshold for Roth IRA contributions. Your total income — including your 401(k) salary, any side income, investment income, and other earnings — determines whether you can contribute to a Roth IRA at all.

Income limits for Roth IRA contributions when you have a 401(k)

The IRS uses your modified adjusted gross income (MAGI) to decide whether you can contribute to a Roth IRA. MAGI includes your W-2 wages from your job, which is where your 401(k) contributions come from. A higher salary means higher MAGI, which can push you above the Roth IRA income limit.

The income limit ranges vary by filing status and change each year. If you are single, the range is lower than if you are married filing jointly. If your income falls within the phase-out range, you can contribute a reduced amount. If your income exceeds the upper limit, you cannot contribute to a Roth IRA that year.

The fact that you contribute to a 401(k) does not lower your MAGI for Roth IRA purposes. Your 401(k) contributions reduce your taxable income on your tax return, but the IRS still counts your full salary when calculating whether you meet the Roth IRA income limit.

When both accounts make sense together

Many people contribute to both a 401(k) and a Roth IRA because the accounts serve different purposes. A 401(k) often comes with an employer match — information programs your employer adds if you contribute — so most people fund it first to capture that match. After that, a Roth IRA offers tax-free growth and tax-free withdrawals in retirement, which a 401(k) does not.

If your income is in the middle range — high enough to have a 401(k) but not so high that you exceed the Roth IRA income limit — you can use both accounts to save more for retirement than either account alone would allow. This is especially useful if your employer's 401(k) has high fees or limited investment options, because the Roth IRA gives you more control over how your money is invested.

Some people also use this strategy to diversify their tax situation. Money in a 401(k) is taxed as ordinary income when you withdraw it in retirement. Money in a Roth IRA comes out tax-free. Having both types of accounts means you have more flexibility in managing your tax bill later.

What happens if your income rises above the Roth IRA limit

If your income exceeds the upper limit for Roth IRA contributions, you cannot contribute directly to a Roth IRA that year, even if you want to. This can happen if you get a raise, a bonus, or additional income from a side job. The 401(k) contribution limit does not change based on income, so you can still contribute to your 401(k) at work.

If you are above the Roth IRA income limit but still want to fund a Roth account, you have another option: a backdoor Roth conversion. This involves contributing money to a traditional IRA and then converting it to a Roth IRA. The conversion itself is not limited by income, though it has tax consequences you should understand before attempting it.

A backdoor Roth is a separate strategy from contributing to both a 401(k) and a Roth IRA directly, and it involves more steps and tax planning. If your income is above the Roth limit, you may want to discuss this option with a tax professional.

Employer plans and income calculations

If you have a 401(k) at work, that employer plan does not prevent you from opening or contributing to a Roth IRA. However, some employer plans do affect whether you can contribute to a traditional IRA and deduct that contribution on your taxes. This rule does not explore to Roth IRAs, which have their own income limits but are not affected by whether you have an employer plan.

The presence of a 401(k) does matter for your income calculation, though. Your 401(k) salary is part of your MAGI, which determines your Roth IRA may be able to access. If you have a high-paying job with a 401(k), you are more likely to exceed the Roth IRA income limit than someone with a lower salary.

Tracking contributions across both accounts

You are responsible for tracking how much you contribute to each account during the year. Your 401(k) administrator sends you statements showing your contributions. Your Roth IRA provider does the same. At tax time, you report your Roth IRA contributions on Form 8606 if you also have a traditional IRA or if you did a conversion.

If you contribute more than the annual limit to a Roth IRA, the IRS charges a 6 percent penalty tax on the excess amount each year until you remove it. This is why it is important to know the current year's limit before you contribute and to keep track of how much you have already put in.

If you have multiple Roth IRAs at different banks or brokers, the contribution limit applies to all of them combined, not to each account separately. The same rule applies to traditional IRAs. You cannot split a $7,000 limit across three different Roth IRAs and contribute $7,000 to each one.

Frequently Asked Questions

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

No. The 401(k) contribution limit and the Roth IRA contribution limit are separate. Money you put into a 401(k) does not reduce your Roth IRA limit. However, your 401(k) salary counts toward your income, which determines whether you are may be able to access to contribute to a Roth IRA at all.

What if I max out my 401(k) and still have money to save?

You can contribute to a Roth IRA if your income is within the limit. The Roth IRA has a lower annual limit than a 401(k), but it offers tax-free growth and withdrawals. If you exceed the Roth IRA income limit, a backdoor Roth conversion is another option, though it involves more steps.

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

Yes. Whether your employer offers a 401(k) does not affect your ability to open or contribute to a Roth IRA. Your income still determines your may be able to access, but the presence or absence of an employer plan does not change that.

What is MAGI and why does it matter for Roth contributions?

MAGI is modified adjusted gross income, which includes your salary, self-employment income, investment income, and other earnings. The IRS uses MAGI to determine whether you can contribute to a Roth IRA. Your 401(k) salary is part of your MAGI, so a higher salary can push you over the income limit.

If I am over the Roth IRA income limit, can I still contribute to a 401(k)?

Yes. The 401(k) contribution limit does not depend on income. You can contribute to a 401(k) at any income level. Only the Roth IRA has income limits that can prevent you from contributing.
