IRA vs. 401(k): Which One Should You Use?

“An investment in knowledge pays the best interest.”

— Benjamin Franklin

This is one of the most common questions I get.

“Should I put my money in my 401(k) or an IRA?”

After nearly 30 years of helping people retire, my answer is usually the same: it depends. And often, the real answer is both.

Let me break down how these two accounts work, where they overlap, and how to think about which one deserves your dollars.

The Basics

A 401(k) is a retirement account offered through your employer. Money comes out of your paycheck automatically, before you ever see it. If your company offers a match, they’ll contribute additional money based on how much you put in.

An IRA — Individual Retirement Account — is something you open on your own. You fund it directly from your bank account. Anyone with earned income can open one, regardless of whether they have a workplace plan.

Both accounts let your investments grow tax-advantaged. Both come in traditional and Roth versions. Both have rules about when you can take money out without penalties.

But there are some important differences.

Contribution Limits

This is where the 401(k) has a big advantage.

In 2026, you can contribute up to $24,500 to a 401(k). If you’re 50 or older, you can add another $8,000 in catch-up contributions — bringing your total over $32,000. If you’re between 60 and 63, the catch-up limit jumps even higher to $11,250.

IRAs have much lower limits. In 2026, you can contribute $7,500 — or $8,600 if you’re 50 or older.

If you’re trying to save aggressively for retirement, the 401(k) gives you a lot more room.

The Employer Match

This is the 401(k)’s superpower.

Many employers will match a portion of what you contribute. A common formula is dollar-for-dollar up to 3% of your salary, or 50 cents on the dollar up to 6%. The specifics vary by company.

Here’s the thing. That match is free money. If your employer offers a match and you’re not contributing enough to get the full amount, you’re leaving compensation on the table.

This is why I usually tell people, at a minimum, contribute enough to your 401(k) to capture the full match. This is free money. You get 100% or 50% return on that matched money. After that, you can decide where additional dollars should go.

IRAs don’t have employer contributions. It’s just you.

Investment Options

This is where IRAs have the edge.

With a 401(k), you’re limited to the investment options your employer chooses. Some plans have great options. Some don’t. You’re stuck with whatever’s on the menu.

With an IRA, you open the account wherever you want — Fidelity, Schwab, Vanguard, wherever — and you can invest in almost anything. Stocks. Bonds. ETFs. Mutual funds. You have full control.

If your 401(k) has limited or expensive investment options, it might make sense to contribute just enough to get the match, then put additional savings into an IRA where you have more flexibility.

Income Limits

Here’s where it gets a little complicated.

Roth IRAs have income limits. If you earn too much, you can’t contribute directly. For 2026, the ability to contribute phases out between $153,000 and $168,000 for single filers, and between $242,000 and $252,000 for married couples filing jointly.

Traditional IRAs have income limits too — but only for the tax deduction. If you’re covered by a workplace retirement plan and your income is above certain thresholds, you can still contribute to a traditional IRA, but you won’t be able to deduct the contribution from your taxes. If you made a non-deductible IRA contribution, you may be able to convert it to a ROTH IRA. This is called a Back Door Roth IRA contribution.

401(k)s — even Roth 401(k)s — have no income limits. If your employer offers one and you’re eligible to participate, you can contribute regardless of how much you make.

This makes Roth 401(k)s particularly valuable for high earners who want access to Roth accounts but are locked out of Roth IRAs.

Traditional vs. Roth

Both 401(k)s and IRAs come in two flavors: traditional and Roth.

With a traditional account, you get a tax break now. Contributions reduce your taxable income in the year you make them. The money grows tax-deferred. You pay taxes when you withdraw in retirement.

With a Roth account, you pay taxes now. Contributions are made with after-tax dollars — no deduction upfront. But the money grows tax-free, and qualified withdrawals in retirement are completely tax-free.

The question of traditional vs. Roth is really a question about tax rates. If you think your tax rate will be higher in retirement than it is now, Roth makes sense. If you think it’ll be lower, traditional makes sense.

For most people in their peak earning years, traditional contributions — and the immediate tax deduction — are valuable. For younger workers in lower tax brackets, Roth contributions often make more sense.

And for many people, having a mix of both gives you flexibility in retirement to manage your taxable income strategically.

Required Minimum Distributions

One more difference worth knowing.

Traditional IRAs and traditional 401(k)s require you to start taking withdrawals once you reach age 73 — whether you need the money or not. These are called Required Minimum Distributions, or RMDs.

Roth IRAs don’t have RMDs during your lifetime. You can let that money grow tax-free for as long as you want.

Roth 401(k)s used to have RMDs, but starting in 2024, they no longer do. That makes them more attractive than they used to be.

If you’re still working for the company that sponsors your 401(k), you may be able to delay RMDs from that account until you actually retire. But if you own more than 5% of the company, that exception doesn’t apply.

So Which One Should You Use?

Here’s how I think about it.

Start with the 401(k) match. If your employer offers one, contribute enough to get the full match. That’s an instant return on your money that you can’t get anywhere else.

Then consider your options. If your 401(k) has good, low-cost investment choices, it might make sense to keep contributing there — especially if you want to save more than the IRA limits allow.

If your 401(k) options are limited or expensive, consider maxing out an IRA next. You’ll have more control over your investments.

If you’re a high earner locked out of Roth IRAs, a Roth 401(k) might be your best path to tax-free retirement income.

And if you can afford to do both — max out your 401(k) and contribute to an IRA — that’s often the best position to be in. This may be where you can do a backdoor ROTH IRA contribution as previously discussed.

The Bottom Line

The IRA vs. 401(k) question doesn’t have to be either/or.

Both accounts are valuable. Both have their strengths. The right mix depends on your income, your employer’s plan, your investment preferences, and your tax situation.

The most important thing is that you’re saving. Consistently. Over time. The specific account matters less than the habit of putting money away for your future.
