401(k) vs IRA
Which retirement account is better?
The answer is both — but the order you fund them matters more than which one you pick.
Updated for 2026 contribution limits and tax rules.
Max your 401(k) to the employer match, then max your Roth IRA, then go back and max your 401(k).
The 401(k) wins on contribution limits ($23,500 vs $7,000) and employer matching. The IRA wins on investment flexibility and Roth withdrawal rules. You don't have to choose — you should use both. The question is just which one gets your dollars first, and the answer is whichever one gives you free money (hint: the 401(k) match).

Score: 401(k) wins 5 categories, IRA wins 3, 2 ties. But the real winner is using both strategically.
What is a 401(k)?
A 401(k) is an employer-sponsored retirement savings plan that lets you contribute a portion of your paycheck before taxes (Traditional) or after taxes (Roth). The money grows tax-deferred or tax-free, depending on which type you choose, and you generally can't touch it until age 59.5 without a 10% penalty.
The name comes from Section 401(k) of the Internal Revenue Code — because nothing says “accessible financial planning” like naming your retirement vehicle after a tax code subsection.
In 2026, you can contribute up to $23,500 per year ($31,000 if you're 50 or older). Your employer may also match a portion of your contributions — this is literally free money added on top of your limit.
Traditional 401(k)
- +Contributions reduce your taxable income today
- +Money grows tax-deferred
- -Withdrawals in retirement taxed as income
- -Required minimum distributions at age 73
Best for: High earners who expect a lower tax rate in retirement.
Roth 401(k)
- +Withdrawals in retirement are 100% tax-free
- +No RMDs (as of SECURE 2.0 Act)
- -No tax deduction today — you pay taxes upfront
- -Same contribution limit as Traditional ($23,500)
Best for: Younger workers who expect a higher tax rate in retirement.
Many employers now offer both Traditional and Roth 401(k) options. You can even split your contributions between them — contributing some pre-tax and some after-tax in the same year. Your total across both cannot exceed the $23,500 limit.
What is an IRA?
An Individual Retirement Account (IRA) is a retirement savings account you open on your own — not through an employer. You choose your broker (Fidelity, Vanguard, Schwab, etc.), you choose your investments, and you control everything. The 2026 contribution limit is $7,000 per year ($8,000 if 50 or older).
There are two main types: Traditional IRA (tax-deductible contributions, taxed withdrawals) and Roth IRA (after-tax contributions, tax-free withdrawals). The Roth IRA is generally the better choice for most people, but it has income limits that can block high earners from contributing directly.
The biggest advantage of an IRA over a 401(k) is investment freedom. Your 401(k) might offer 25 mutual funds picked by your HR department. Your IRA gives you access to thousands of ETFs, individual stocks, bonds, REITs, and more. Lower fees, better options, full control.

The Optimal Strategy
The order of operations for retirement savings. Follow this and you'll outperform 90% of Americans by default.
401(k) up to employer match
If your employer matches 50% of contributions up to 6% of salary, contribute at least 6%. On a $80,000 salary, that's $4,800 from you and $2,400 from your employer — a 50% instant return before the money even touches the market. No investment in history beats free money.
Max out your Roth IRA ($7,000)
After capturing the full match, fund your Roth IRA. Why Roth over Traditional? Tax-free growth forever, no required minimum distributions, more investment options than your 401(k), and the ability to withdraw contributions penalty-free. If you're under 50 and earning less than $150K (single), you can contribute directly.
Max out 401(k) to $23,500
Go back to your 401(k) and max it out. The remaining $18,700 (after the match contributions) reduces your taxable income dollar-for-dollar if using Traditional, or grows tax-free if using Roth 401(k). Either way, you're sheltering $23,500 from taxes in some form.
HSA if eligible ($4,300 individual / $8,550 family)
If you have a high-deductible health plan, the Health Savings Account is the only triple-tax-advantaged account: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. After 65, you can withdraw for any reason (just pay income tax, like a Traditional IRA). It's a stealth retirement account.
Taxable brokerage account
Once you've maxed all tax-advantaged accounts, invest in a taxable brokerage. Low-cost index funds (total market or S&P 500) are the move here. You'll pay capital gains taxes, but long-term rates (0-20%) are still favorable. Plus, you have full liquidity — no age restrictions, no penalties, no RMDs.
Total tax-advantaged space in 2026: $23,500 (401k) + $7,000 (IRA) + $4,300 (HSA) = $34,800 per year sheltered from taxes. For couples with two 401(k)s, two IRAs, and an HSA: $65,550.
Employer Match is Free Money
Let's do the math on why you should never leave employer match on the table.
Example: 50% match up to 6% of salary
Your Salary
$80,000
Your Contribution (6%)
$4,800
Employer Match (50%)
$2,400
That's a 50% instant return before your money even touches the market. The S&P 500 averages ~10% per year. Your employer match gives you 50% on day one.
According to the Bureau of Labor Statistics, roughly one in four workers with access to a 401(k) match doesn't contribute enough to get the full match. Collectively, Americans leave an estimated $24 billion in employer matches on the table every year. That's $24 billion in free money — unclaimed.
Even if your 401(k) has high fees and mediocre fund options, the employer match more than compensates. A fund with a 1% expense ratio and a 50% employer match still destroys a zero-fee IRA with no match. Always capture the full match first. Optimize later.
The 30-Year Impact
That $2,400 annual employer match invested at 8% average returns for 30 years:
Without Match (your $4,800 only)
$544,000
With Match ($4,800 + $2,400)
$816,000
The match alone adds $272,000 over 30 years. That's the cost of leaving free money on the table.

What If You Have Both?
Having both a 401(k) and an IRA isn't an either/or situation — it's the ideal setup. They serve different purposes and complement each other perfectly.
Your 401(k) is your workhorse: high contribution limits, employer match, automatic payroll deductions that enforce discipline. But the fund choices are limited to whatever your employer picked, and fees can be higher than you'd like.
Your IRA is your precision tool: total investment freedom, typically lower fees, and (for Roth IRAs) unmatched withdrawal flexibility. The contribution limit is lower, but the quality of your investing is higher.
How They Work Together
This is called asset location — putting the right investments in the right accounts to minimize taxes. It sounds minor, but studies show proper asset location can add 0.25-0.75% to your annual returns. Over 30 years, that compounds into tens of thousands of dollars.
One important caveat: if you have a Traditional 401(k) and want a Traditional IRA deduction too, your IRA deduction may be reduced or eliminated depending on your income. Single filers with a workplace plan lose the deduction above $89,000 MAGI in 2026. This is another reason most people are better off with a Roth IRA (no deduction needed — the benefit is tax-free growth).
Self-Employed? Consider a Solo 401(k) or SEP IRA
If you're self-employed, a freelancer, or a 1099 contractor, you don't have an employer to offer you a 401(k). But you can create your own — and the limits are actually more generous than a regular 401(k).
Solo 401(k)
- +$23,500 employee contribution + 25% of net self-employment income as employer
- +Combined limit: $70,000 ($77,500 if 50+)
- +Roth option available
- +Loan provisions (borrow from yourself)
- -More paperwork; Form 5500-EZ if assets exceed $250K
- -Only for businesses with no employees (other than spouse)
SEP IRA
- +Contribution limit: 25% of net SE income (max $70,000)
- +Dead simple to set up — one form
- +Can have employees (must contribute for all)
- -No Roth option
- -No employee contribution — employer only
- -No loan provisions
Bottom line: If you're a solo freelancer or single-member LLC, the Solo 401(k) is almost always better. You get higher contribution limits at lower income levels, a Roth option, and loan access. The SEP IRA wins on simplicity if you have employees (since you must contribute equally for all employees in a SEP, which gets expensive, but the Solo 401(k) isn't available if you have non-spouse employees).
A self-employed person earning $100,000 in net SE income can contribute roughly $43,500 to a Solo 401(k) ($23,500 + ~$20,000 employer portion) compared to only ~$20,000 in a SEP IRA. That's more than double the tax-advantaged savings.
Rollovers: Moving Money Between Accounts
When you leave a job, your 401(k) doesn't disappear — but it does become an orphan. Your old employer isn't going to optimize it for you. In most cases, rolling it into an IRA is the smart move.
Common Rollover Paths
When to Roll Over
- You left your job — roll to an IRA for better options and lower fees.
- Your old plan has high fees — many small-company 401(k)s charge 1-2% annually. An IRA at Fidelity or Vanguard can cut that to 0.03-0.10%.
- You want to consolidate — if you have four old 401(k)s from four jobs, roll them all into one IRA. Simpler to manage, rebalance, and track.
- You want Roth conversion — rolling to a Traditional IRA first, then converting to Roth over multiple years, lets you spread the tax hit.
When NOT to Roll Over
- You plan to do Backdoor Roth — having a pre-tax IRA balance triggers the pro-rata rule, which makes Backdoor Roth conversions partially taxable. If you're a high earner doing Backdoor Roth, keep pre-tax money in the 401(k).
- Your old plan has institutional funds — some large employers negotiate expense ratios of 0.01-0.02%. You can't get those in a retail IRA.
- You need creditor protection — 401(k)s have stronger federal (ERISA) protection from lawsuits and creditors than IRAs, which vary by state.
- You might retire between 55-59.5 — the Rule of 55 lets you withdraw from your current employer's 401(k) penalty-free if you separate from service at age 55+. IRAs don't have this provision.
Frequently Asked Questions
Can I contribute to both a 401(k) and an IRA?
Yes. The 401(k) and IRA have separate contribution limits. In 2026, you can contribute up to $23,500 to your 401(k) and up to $7,000 to an IRA ($31,000 and $8,000 respectively if you're 50 or older). However, your ability to deduct Traditional IRA contributions may be limited if you or your spouse have access to a workplace 401(k) and your income exceeds certain thresholds.
Should I max out my 401(k) or IRA first?
The optimal order is: (1) Contribute to your 401(k) up to the employer match — that's free money with an instant 50-100% return. (2) Max out a Roth IRA for the tax-free growth, investment flexibility, and no RMD advantage. (3) Go back and max out your 401(k) to $23,500. (4) If you still have money, consider a taxable brokerage account or HSA if eligible.
What is the income limit for a Roth IRA in 2026?
For 2026, you can contribute the full amount to a Roth IRA if your modified adjusted gross income (MAGI) is below $150,000 (single) or $236,000 (married filing jointly). Contributions phase out between $150,000-$165,000 for single filers and $236,000-$246,000 for married filing jointly. If you exceed these limits, you can use the Backdoor Roth IRA strategy.
Is a Roth 401(k) better than a Traditional 401(k)?
It depends on your current vs. future tax rate. If you expect to be in a higher tax bracket in retirement (likely if you're young and early in your career), Roth 401(k) is generally better — you pay taxes now at a lower rate and withdraw tax-free later. If you're in your peak earning years and expect a lower tax rate in retirement, Traditional 401(k) lets you defer taxes now when they hurt the most.
What happens to my 401(k) if I leave my job?
You have four options: (1) Leave it in your former employer's plan (if allowed). (2) Roll it over to your new employer's 401(k). (3) Roll it over to a Traditional IRA — this gives you full control and usually better investment options. (4) Cash it out — avoid this if possible, as you'll pay income taxes plus a 10% penalty if under 59.5. A direct rollover to an IRA is usually the best move.
What is a Backdoor Roth IRA?
A Backdoor Roth IRA is a legal strategy for high earners who exceed Roth IRA income limits. You contribute to a Traditional IRA (non-deductible), then immediately convert it to a Roth IRA. Since you already paid taxes on the contribution, the conversion is tax-free (assuming you have no other pre-tax IRA balances — watch out for the pro-rata rule). This effectively lets anyone contribute to a Roth IRA regardless of income.
Can I withdraw from my 401(k) or IRA before age 59.5?
You can, but you'll generally pay a 10% early withdrawal penalty plus income taxes on Traditional accounts. Exceptions include: disability, first-time home purchase (IRA only, up to $10K), substantially equal periodic payments (Rule 72(t)), certain medical expenses, and the Rule of 55 for 401(k)s (penalty-free withdrawals if you leave your job at age 55 or later). Roth IRA contributions (not earnings) can be withdrawn anytime tax- and penalty-free.
How much should I contribute to my 401(k)?
At minimum, contribute enough to get the full employer match — anything less is leaving free money on the table. The classic advice is to save 15-20% of your gross income for retirement across all accounts. If you're starting late (after 35), aim for 20-25%. If you started at 22 and invest consistently, even 10-12% can build substantial wealth thanks to compound interest over 40+ years.
Is a SEP IRA or Solo 401(k) better for self-employed people?
A Solo 401(k) is generally more flexible. In 2026, a Solo 401(k) lets you contribute up to $23,500 as an employee plus 25% of net self-employment income as the employer, with a combined limit of $70,000 ($77,500 if 50+). A SEP IRA only allows employer contributions of up to 25% of net self-employment income (max $70,000). The Solo 401(k) also offers a Roth option and loan provisions. The SEP IRA is simpler to set up but less powerful.
Should I roll my old 401(k) into an IRA?
In most cases, yes. An IRA rollover gives you full control over your investments, typically lower fees, and access to thousands more funds. The main exception is if your old 401(k) has institutional-class funds with extremely low expense ratios (some large employer plans offer this), or if you might need the stronger creditor protection that ERISA provides for 401(k)s. Always do a direct rollover (trustee-to-trustee) to avoid the 20% mandatory withholding on indirect rollovers.
The Bottom Line
The 401(k) vs IRA debate is a false choice. You need both. The 401(k) gives you scale (high limits + employer match) and the IRA gives you precision (investment freedom + Roth flexibility). Together, they let you shelter $30,500+ per year from taxes while building a diversified, low-cost retirement portfolio.
The only wrong answer is not investing at all. Every year you delay costs you far more than choosing the “wrong” account type. A 25-year-old who invests $500/month in either account at 8% returns will have $1.05 million by 60. A 35-year-old starting the same contribution has $440,000. The 10-year head start is worth more than $600,000.
Start with the match. Fund the Roth. Max the 401(k). Repeat for 30 years. Retire with dignity.
