Max Out 401k and IRA: Both at Once?

Yes, you can max out both a 401(k) and an IRA in the same year. For 2025, the elective deferral limit for a 401(k) is $23,500 (plus a $7,500 catch-up if you’re 50 or older), and the IRA contribution limit is $7,000 (plus a $1,000 catch-up). However, whether you can contribute the full IRA amount depends on your income and whether you (or your spouse) have access to a workplace plan.

How 401(k) and IRA Limits Work

The IRS sets annual contribution limits for retirement accounts. These limits are per person, per account type, not per employer. So if you have two 401(k)s (e.g., from a previous job and a current one), the total you can contribute across both is still $23,500 in 2025. The same applies to IRAs: you can have multiple IRAs, but the total contribution across all of them cannot exceed $7,000.

It’s important to distinguish between employee deferrals (the money you elect to put in from your paycheck) and employer contributions (matching or profit-sharing). Employer contributions do not count toward your personal limit, but they do count toward the overall plan limit, which is $70,000 for 2025 (or $77,500 with catch-up).

Income Limits for IRA Contributions

Your ability to deduct traditional IRA contributions or contribute to a Roth IRA directly depends on your income and filing status. If you or your spouse has a workplace retirement plan, the deduction phase-out ranges are:

• Single, covered by a workplace plan: phase-out starts at $79,000 and ends at $89,000 for 2025.
• Married filing jointly, covered by a workplace plan: phase-out starts at $126,000 and ends at $146,000.
• Married filing jointly, spouse not covered but you are: phase-out starts at $236,000 and ends at $246,000.

If your income exceeds these ranges, you can still contribute to a non-deductible traditional IRA, but you won’t get a tax deduction. Roth IRA contributions have their own income limits: for single filers, the phase-out is $150,000–$165,000; for married filing jointly, it’s $236,000–$246,000.

Roth vs. Traditional: Which to Max First?

If you can’t max out both, the common advice is to contribute enough to your 401(k) to get the full employer match (that’s free money), then max out a Roth IRA if you’re eligible, then return to the 401(k) to max it out. This order works because IRAs often offer more investment choices and lower fees than employer plans. However, if your 401(k) has exceptional low-cost index funds, you might prioritize it instead. The best choice depends on your tax situation now versus in retirement.

Common Mistakes and Misconceptions

One frequent mistake is assuming that if you max out your 401(k), you can’t also contribute to an IRA. That’s false—they are separate limits. Another is forgetting that the IRA limit is per person, so a married couple can contribute $14,000 total (if both are under 50). Also, many people confuse the deduction limit with the contribution limit. You can always contribute up to $7,000 to a traditional IRA, but you may not be able to deduct all of it.

How to Actually Max Out Both

Here’s a step-by-step approach to maxing out both accounts:

1. Check your 401(k) plan: Log in to your plan and confirm the contribution limit for the year. Set your deferral percentage so that by the last paycheck, you reach exactly $23,500 (or $31,000 if 50+).
2. Open an IRA: Choose a traditional or Roth IRA at a brokerage. Fund it with up to $7,000 (or $8,000 if 50+).
3. Monitor your income: If you’re near the phase-out ranges, calculate your modified adjusted gross income (MAGI) to see if your IRA contribution is deductible or if you should use a Roth.
4. Contribute early: For IRAs, you can contribute for the previous tax year until April 15 of the next year. This gives you extra time to fund it.

What If You Can’t Max Both?

If your budget only allows one, prioritize the 401(k) match first. Then, if you have extra, consider the IRA. If you’re in a high tax bracket now, a traditional 401(k) reduces your current taxes. If you expect to be in a higher bracket in retirement, a Roth IRA gives you tax-free withdrawals. There’s no one-size-fits-all answer, but the general rule is: match > Roth IRA > traditional 401(k) > taxable brokerage.

Frequently Asked Questions

Can I contribute to both a 401(k) and an IRA in the same year?

Yes, absolutely. The IRS allows you to contribute to both a 401(k) and an IRA, up to the individual limits for each. Your 401(k) contributions do not reduce your IRA limit, and vice versa.

What is the 401(k) contribution limit for 2025?

The limit is $23,500 for employee deferrals. If you’re age 50 or older, you can add a $7,500 catch-up contribution, making the total $31,000.

What is the IRA contribution limit for 2025?

The limit is $7,000 for those under 50, and $8,000 for those 50 and older. This applies to the total of all your traditional and Roth IRAs combined.

If my income is too high for a Roth IRA, can I still contribute to a traditional IRA?

Yes, you can contribute to a traditional IRA regardless of income, but you may not be able to deduct the contribution if you or your spouse has a workplace plan and your income exceeds the phase-out range. You could also consider a backdoor Roth IRA, but that involves converting the traditional IRA to a Roth, which has its own rules.

Does maxing out my 401(k) affect my employer match?

No, employer matches are separate. However, if you hit the $23,500 limit early in the year, some employers stop matching for the rest of the year (true-up provisions vary). To avoid missing out, spread your contributions evenly across all paychecks.

Can I max out a 401(k) and an IRA if I’m self-employed?

Yes, but you’d use a solo 401(k) or SEP IRA instead of a regular 401(k). The solo 401(k) allows you to contribute both as an employee (up to $23,500) and as an employer (up to 25% of compensation), with a total limit of $70,000 for 2025.
