When you have limited savings to invest each year, choosing between your 401(k) and an IRA can feel paralyzing. Both accounts offer tax advantages for retirement, but the order in which you fund them matters significantly for maximizing your long-term wealth.

Start with the 401(k) Match

The first rule is simple: if your employer offers a 401(k) match, contribute enough to capture the full match before putting money anywhere else. According to the U.S. Department of Labor, an employer match is free money that delivers an immediate 50% to 100% return on your contribution, depending on the match formula.

For example, if your employer matches 50% of contributions up to 6% of your salary, and you earn $60,000 annually, contributing $3,600 (6% of salary) unlocks an additional $1,800 from your employer. No other investment offers that guaranteed return. Missing the match is leaving compensation on the table.

Move to an IRA After the Match

Once you have captured the full employer match, your next dollars typically belong in an IRA (either Traditional or Roth, depending on your tax situation). The IRA offers two key advantages over most 401(k) plans: broader investment choices and potentially lower fees.

While 401(k) plans limit you to a curated menu of mutual funds or target-date funds selected by your employer, an IRA at a brokerage allows you to invest in individual stocks, bonds, ETFs, index funds, and thousands of mutual funds. This flexibility lets you build a lower-cost, more diversified portfolio. As covered in foundational texts such as Principles of Finance, investment costs compound over decades and directly reduce your retirement balance.

For 2026, the IRS allows IRA contributions of up to $7,000 annually ($8,000 if you are age 50 or older). If you can afford to max out this amount after securing your employer match, you position yourself for better long-term growth through cost control and investment selection.

Return to the 401(k) for Additional Savings

After maxing your IRA, circle back to your 401(k) and contribute as much as you can toward the annual limit. For 2026, 401(k) contribution limits are $23,000 ($30,500 if age 50 or older). The higher contribution ceiling makes the 401(k) the primary vehicle for aggressive savers once the IRA is maxed.

Even without additional employer matching, the 401(k) offers tax deferral (Traditional) or tax-free growth (Roth 401(k)), and contributions reduce your current taxable income if you choose the Traditional option. High earners who exceed IRA income limits for deductibility or Roth contributions will find the 401(k) especially valuable at this stage.

Roth vs. Traditional Considerations

At each step, you face a secondary choice: Traditional (tax-deferred) or Roth (tax-free in retirement). Traditional contributions reduce your taxable income now but are taxed as ordinary income when withdrawn. Roth contributions are made with after-tax dollars but grow and withdraw tax-free in retirement.

Your decision hinges on whether you expect to be in a higher or lower tax bracket in retirement. Younger workers in lower brackets often benefit from Roth accounts, while mid-career high earners may prefer Traditional to reduce current taxes. Note that Roth IRA contributions phase out at higher income levels, but Roth 401(k) options have no income limits.

The SEC’s investor education resources emphasize the importance of understanding these tax trade-offs before committing to a strategy, as changing account types mid-career can create tax friction.

Income Limits and Backdoor Strategies

High earners may face restrictions. Roth IRA contributions phase out starting at $146,000 for single filers and $230,000 for married couples filing jointly (2026 figures). Traditional IRA deductions also phase out if you are covered by a workplace retirement plan and earn above certain thresholds.

In these cases, a backdoor Roth IRA (contributing to a Traditional IRA and immediately converting to Roth) or focusing exclusively on 401(k) contributions may be necessary. Consult a CPA or financial advisor to navigate these strategies, as they involve specific tax reporting requirements.

The Bottom Line

The optimal funding sequence for most savers is: (1) contribute to your 401(k) up to the employer match, (2) max out an IRA, (3) return to the 401(k) and contribute up to the annual limit. This order captures free money first, then exploits the IRA’s flexibility and lower costs, and finally takes advantage of the 401(k)‘s higher contribution ceiling.
