401(k) vs. IRA: Which Should You Fund First?

Why trust this guide: built on the IRS's official 2026 contribution limits, with original math on the employer match and an honest order of moves — not a pitch for any account. We name who each step is wrong for. Our editorial standards are public.

A 401(k) is a retirement account your employer offers, usually with money taken straight from your paycheck and often an employer match on top. An IRA (individual retirement account) is one you open yourself at a brokerage, with no employer involved. The good news: choosing between them is mostly a false choice. For most people there's a clear funding order — get your full 401(k) match first, then fund an IRA, then come back to the 401(k). This guide explains why that order works and when to break it.

If you only remember one line, make it this: never walk past free money. A 401(k) match is the highest guaranteed return you'll ever get, so it comes before everything else — including the IRA most experts otherwise love.

What's the difference between a 401(k) and an IRA?

A 401(k) is an employer plan: higher contribution limits, possible matching, but a fixed menu of funds someone else picked. An IRA is your own account: lower limit, no match, but you can hold almost any low-cost fund and usually pay less in fees. One gives you free money and big tax-advantaged room; the other gives you control and choice.

Both come in traditional (tax break now, taxed later) and Roth (taxed now, tax-free later) flavors. That choice is a separate decision — we cover it in Roth vs. traditional IRA for beginners. This guide is about which account to feed first, not which tax treatment to pick.

So which should you fund first?

Fund them in this order, working down the list only after each step is full: (1) your 401(k) up to the full employer match, (2) an IRA up to its limit, (3) back to the 401(k) up to its limit, (4) a regular taxable brokerage. Each level is a slightly worse deal than the one above it, so you climb down only when you've used up the better space.

Step 1: Get the full employer 401(k) match

If your employer matches contributions, this is always move number one. A match is an immediate, guaranteed return on your money — commonly 50 cents or a full dollar for every dollar you put in, up to a percentage of your salary. No investment on earth reliably pays you 50–100% the moment you buy in. Contribute at least enough to capture every matched dollar; anything less is leaving part of your paycheck unclaimed.

Step 2: Max out an IRA

Once the match is captured, the next dollar usually does better in an IRA than in the 401(k). Here's why: a 401(k) limits you to the funds your plan chose, and some plans carry high fees. An IRA you open yourself lets you buy nearly any low-cost index fund or ETF, often with lower expenses. For 2026 you can contribute up to $7,500 ($8,600 if you're 50 or older). A Roth IRA is a popular choice here because qualified withdrawals are tax-free — see how to start a Roth IRA in your 20s for the setup.

Step 3: Go back and max the 401(k)

Filled the IRA and still have money to invest? Return to the 401(k) and push toward its much larger $24,500 limit (2026). You've already got the match and the low-cost IRA; now you're after sheer tax-advantaged room. The 401(k)'s high ceiling is its superpower — it lets you shelter far more than an IRA can once you're saving seriously. Bonus: 401(k) contributions come straight out of your paycheck, so the money is invested before you can spend it.

Step 4: Then a taxable brokerage

If you've maxed both tax-advantaged accounts — genuinely impressive — the next stop is an ordinary taxable brokerage. There's no contribution limit and no tax break, but also no early-withdrawal rules: you can sell whenever you need to. It's the right home for money you're investing beyond retirement, or for goals between "five years away" and "retirement."

A worked example: the match is an instant raise

Picture two coworkers, both earning $50,000, both able to invest $2,500 this year. One contributes 5% to a 401(k) with a dollar-for-dollar match; the other skips the 401(k) and puts the same $2,500 straight into an IRA.

Same effort, same paycheck hit — but the matched 401(k) starts with twice the money. That head start compounds for decades. It's the single clearest reason the match jumps the line ahead of the otherwise-excellent IRA. Run your own numbers in the compound interest calculator or check your trajectory with the retirement calculator.

What if you don't have a 401(k) — or there's no match?

The order assumes a matched 401(k); plenty of people don't have one. Adjust like this:

• No match, but you have a 401(k): Fund the IRA first (more control, lower fees), then use the 401(k) for its big limit and payroll automation. If your plan's fees are ugly, lean even harder on the IRA.
• No 401(k) at all: The IRA becomes your main retirement account. Max it, then a taxable brokerage. You can still build serious wealth — you just lose the higher limit and the match.
• Self-employed or a side hustle: Look at a SEP-IRA or Solo 401(k), which allow much larger contributions than a regular IRA. (Our side-hustle taxes guide touches on why sheltering self-employment income matters.)
• High earner above the Roth limit: Direct Roth IRA contributions phase out between $153,000 and $168,000 (single) and $242,000 and $252,000 (married filing jointly) for 2026. Above that, people use a traditional 401(k) and a "backdoor Roth" — worth a professional's review, not a DIY guess.

Common mistakes

• Leaving the match on the table. Not contributing enough to get the full match is the costliest error here — it's declining a guaranteed return.
• Stopping at the match. The match is step one, not the finish line. A few percent of salary rarely funds a comfortable retirement on its own.
• Ignoring 401(k) fees. A plan stuffed with high-cost funds is exactly why the IRA comes before maxing the 401(k). Check your fund expense ratios.
• Cashing out an old 401(k) when you change jobs. Roll it into an IRA or your new plan instead — cashing out triggers taxes, likely a 10% penalty, and erases years of growth.
• Leaving the money as cash. Opening and funding the account isn't investing. You still have to buy a fund inside it, or it just sits there.

Who should skip this (and the hard cases)

If you have no earned income, you generally can't contribute to a 401(k) or IRA at all — both require earned income (a spousal IRA is the main exception). If you're carrying high-interest debt, pause after capturing the match and attack the debt; its guaranteed "return" beats the market's uncertain one. And if you have no emergency fund, build a small cushion first so a surprise bill doesn't force you to raid retirement accounts (start with how to build an emergency fund).

For nearly everyone else, the order holds: match, IRA, max the 401(k), taxable. Pick one low-cost fund, automate the contribution, and let time do the heavy lifting.

Quick answers

Should I contribute to a 401(k) or an IRA first? Fund your 401(k) up to the full employer match first — that match is free money and an instant return nothing else matches. After the match, fund an IRA (more investment choice, often lower fees) up to its limit, then go back and contribute more to the 401(k). Only skip the 401(k) first if there's no match.

Can I contribute to both a 401(k) and an IRA in the same year? Yes. The limits are separate, so in 2026 you could contribute up to $24,500 to a 401(k) and up to $7,500 to an IRA. Your ability to deduct a traditional IRA contribution, or contribute to a Roth, may be reduced at higher incomes if you're covered by a workplace plan.

How much do I need to contribute to get the full employer match? Enough to reach whatever percentage your employer matches up to — often around 3% to 6% of your salary. Check your plan's match formula (for example, "100% of the first 5%") and contribute at least that percentage. Anything less leaves matched dollars unclaimed.

Is a 401(k) or an IRA better? Neither is strictly better — they do different jobs. The 401(k) wins on employer matches and a high contribution limit; the IRA wins on investment choice and lower fees. That's exactly why the smart move is to use both in order rather than picking one.

What happens to my 401(k) if I leave my job? Your contributions are always yours; employer match dollars are yours once vested. When you leave, you can typically leave it in the old plan, roll it into your new employer's plan, or roll it into an IRA. Avoid cashing it out — that usually means taxes plus a 10% early-withdrawal penalty.
