401(k) vs IRA: Which Retirement Account Is Better?
Both 401(k) plans and IRAs help you save for retirement with tax advantages, but they differ in contribution limits, investment choices, and employer benefits. This guide compares them side by side so you can build the right strategy.
Quick Comparison
| Factor | 401(k) | IRA |
|---|---|---|
| Contribution Limit (2026) | $23,500 ($31,000 if age 50+) | $7,000 ($8,000 if age 50+) |
| Tax Treatment | Traditional (pre-tax) or Roth (after-tax) | Traditional (tax-deductible) or Roth (after-tax) |
| Employer Match | Yes — often 50-100% of first 3-6% of salary | No employer match available |
| Investment Choices | Limited to plan menu (typically 15-30 funds) | Nearly unlimited (stocks, bonds, ETFs, mutual funds) |
| Early Withdrawal | 10% penalty + taxes before age 59.5 (with exceptions) | 10% penalty + taxes; Roth contributions withdrawable anytime |
| Required Minimum Distributions | Starting at age 73 for Traditional (Roth 401k exempt from 2024) | Age 73 for Traditional; no RMDs for Roth IRA |
How 401(k) Plans Work
A 401(k) is an employer-sponsored retirement plan that lets you contribute a portion of your paycheck before taxes (Traditional) or after taxes (Roth). In 2026, you can contribute up to $23,500, or $31,000 if you are 50 or older thanks to the catch-up provision. Many employers match a percentage of your contributions, commonly 50% of the first 6% of your salary. On a $75,000 salary, a 50% match on 6% means your employer adds $2,250 per year for free.
The main drawback of 401(k) plans is limited investment options. Your employer selects a menu of mutual funds and target-date funds, typically 15 to 30 choices. Expense ratios vary widely: some large employers negotiate institutional rates below 0.05%, while small business plans may charge 0.5% to 1% or more. These fees compound significantly over decades. A $500,000 portfolio paying 0.8% in fees versus 0.05% loses roughly $150,000 over 30 years to the fee difference alone.
How IRAs Work
An Individual Retirement Account (IRA) is opened independently at a brokerage of your choice. The 2026 contribution limit is $7,000, or $8,000 if you are 50 or older. While the limit is much lower than a 401(k), IRAs offer far greater investment flexibility. You can buy individual stocks, bonds, ETFs, mutual funds, REITs, and more from thousands of options.
Traditional IRA contributions may be tax-deductible depending on your income and whether you have an employer plan. For 2026, the deduction phases out for single filers covered by a workplace plan at $79,000 to $89,000 of modified adjusted gross income (MAGI). Roth IRA contributions are never deductible, but qualified withdrawals are entirely tax-free. Roth IRA income limits for 2026 phase out at $150,000 to $165,000 for single filers and $236,000 to $246,000 for married filing jointly.
When to Prioritize Your 401(k)
- Your employer offers a match. Always contribute enough to get the full match first. A 50% match is an immediate 50% return on your money, unbeatable by any investment.
- You want to maximize tax-deferred savings. The $23,500 limit lets you shelter far more income than an IRA's $7,000 cap.
- Your plan has low-cost index funds. If your 401(k) offers broad index funds with expense ratios under 0.1%, the investment limitation is minimal.
- You earn too much for a Roth IRA. High earners above the Roth IRA income limits can still use a Roth 401(k) if their employer offers one, with no income restriction.
When to Prioritize Your IRA
- Your 401(k) has high fees. If your employer plan charges 0.5% or more in fund expenses and administrative fees, fund your IRA first (after capturing any employer match).
- You want maximum investment control. An IRA at a major brokerage gives you access to thousands of ETFs, individual stocks, and bond funds.
- You want a Roth IRA for tax-free growth. Roth IRAs have no RMDs during your lifetime, making them powerful for long-term compounding and estate planning.
- You are self-employed without a 401(k). If you do not have access to an employer plan, an IRA is your primary tax-advantaged option (though a Solo 401(k) or SEP IRA may offer higher limits).
The Optimal Strategy: Use Both
Most financial advisors recommend a three-step approach: first, contribute to your 401(k) up to the employer match. Second, max out your IRA ($7,000 in 2026). Third, return to your 401(k) and increase contributions toward the $23,500 cap. This strategy captures free employer money, takes advantage of the IRA's superior investment options, and maximizes your total tax-advantaged savings at $30,500 per year (or $39,000 if you are 50+).
