What Are 401(k) and IRA Accounts?

Before exploring whether you can contribute to both, let’s clarify what these accounts are and how they function in the U.S. retirement system.

Understanding a 401(k)

A 401(k) is an employer-sponsored retirement plan that allows employees to save pre-tax income for retirement. Many employers offer a matching contribution, essentially giving you "free money" to boost your savings. In 2025, the rules and limits are set by the IRS, and these plans are popular among U.S. workers for their tax advantages and high contribution ceilings.

Understanding an IRA

An IRA, or Individual Retirement Account, is a personal retirement account you can open independently of an employer. There are two main types: Traditional IRAs (pre-tax contributions with tax-deferred growth) and Roth IRAs (after-tax contributions with tax-free withdrawals). IRAs offer more investment flexibility than 401(k)s but come with stricter contribution limits.

Can You Contribute to Both a 401(k) and IRA in the USA?

Yes, U.S. tax laws allow you to contribute to both a 401(k) and an IRA in the same year, as long as you meet eligibility requirements. These accounts are not mutually exclusive, meaning you can use both to diversify your retirement strategy. However, there are key factors to consider:

• Income Limits: Your ability to deduct Traditional IRA contributions or contribute to a Roth IRA depends on your income and whether you’re covered by a 401(k) at work.
• Contribution Caps: Each account has its own annual limit, and contributing to one doesn’t reduce the limit of the other.
• Tax Benefits: Combining these accounts can optimize your tax strategy, depending on your current and future tax brackets.

Let’s break this down further.

2025 Contribution Limits for 401(k) and IRA

To understand how much you can save, you need to know the IRS contribution limits for 2025. These limits are adjusted periodically for inflation, so they may differ slightly from previous years.

401(k) Contribution Limits in 2025

• Employee Contribution: Up to $23,500 per year for those under 50.
• Catch-Up Contribution: An additional $7,500 for those 50 and older, bringing the total to $31,000.
• Total Contribution (Employee + Employer): Up to $70,500 (or $78,000 with catch-up), including employer matches.

IRA Contribution Limits in 2025

• Traditional and Roth IRA Combined: Up to $7,000 per year for those under 50.
• Catch-Up Contribution: An additional $1,000 for those 50 and older, totaling $8,000.
• Note: This limit applies across all your IRAs (Traditional and Roth combined), not per account.

Since the 401(k) and IRA have separate limits, you could theoretically contribute $23,500 to a 401(k) and $7,000 to an IRA in 2025 if you’re under 50—totaling $30,500 in personal contributions alone!

Eligibility and Restrictions

While you can contribute to both, there are eligibility rules and restrictions to watch out for, especially with IRAs.

401(k) Eligibility

• You must work for an employer offering a 401(k) plan.
• There are no income limits restricting contributions or tax deductions.

Traditional IRA Eligibility

• Anyone with earned income can contribute to a Traditional IRA.
• Tax Deduction Limits: If you (or your spouse) are covered by a 401(k) at work, your ability to deduct Traditional IRA contributions phases out based on your Modified Adjusted Gross Income (MAGI):
  • Single filers: Deduction phases out between $80,000 and $90,000 in 2025.
  • Married filing jointly: Phases out between $129,000 and $149,000.
• If you’re not covered by a workplace plan, there’s no income limit for deductions.

Roth IRA Eligibility

• Roth IRA contributions are limited by income:
  • Single filers: Phase-out begins at $146,000, fully ineligible at $161,000.
  • Married filing jointly: Phase-out begins at $230,000, fully ineligible at $240,000.
• If your income exceeds these limits, you can’t contribute directly to a Roth IRA, even if you have a 401(k).

Benefits of Contributing to Both a 401(k) and IRA

Why bother with both? Combining a 401(k) and IRA offers unique advantages for U.S. savers:

• Higher Savings Potential: Maxing out both accounts lets you save more than relying on just one.
• Tax Diversification: A 401(k) and Traditional IRA offer pre-tax savings, while a Roth IRA provides tax-free growth—hedging against future tax rate changes.
• Employer Match: A 401(k) often includes free employer contributions, which you’d miss out on without participating.
• Investment Options: IRAs typically offer more flexibility to invest in stocks, ETFs, or even real estate, compared to the limited options in many 401(k) plans.
• Control: An IRA gives you independence from your employer’s plan, which is useful if you change jobs.

Strategies to Maximize Both Accounts in 2025

Here’s how to make the most of contributing to both a 401(k) and IRA in the USA:

1. Prioritize the 401(k) Match: Contribute enough to your 401(k) to get the full employer match—it’s essentially a 100% return on your money.
2. Max Out Your IRA: If your income allows, fund a Roth IRA for tax-free growth or a Traditional IRA for a tax deduction.
3. Backdoor Roth IRA: If your income exceeds Roth limits, contribute to a Traditional IRA and convert it to a Roth (consult a tax professional).
4. Catch-Up Contributions: If you’re 50+, use the extra $7,500 (401(k)) and $1,000 (IRA) to accelerate savings.
5. Rebalance Annually: Review your investments in both accounts to ensure they align with your retirement goals.

Common Mistakes to Avoid

Contributing to both accounts is smart, but watch out for these pitfalls:

• Overlooking Income Limits: High earners may miss out on Roth contributions or Traditional IRA deductions.
• Exceeding Contribution Limits: Going over the IRS caps can trigger penalties—track your contributions carefully.
• Ignoring Fees: Some 401(k) plans have high fees; compare them to low-cost IRA options.
• Not Planning Withdrawals: Early withdrawals from either account can incur taxes and penalties—plan ahead.

Should You Contribute to Both a 401(k) and IRA?

The decision depends on your financial situation:

• Yes, if: You have extra income to invest, want tax flexibility, or your 401(k) has limited investment options.
• Maybe not, if: You’re stretched thin financially or your employer offers a generous 401(k) match that meets your needs.

For most Americans, using both accounts is a powerful way to build wealth for retirement. Consult a financial advisor to tailor this strategy to your goals.
