IRA vs 401(k): Which One to Fund First

Your employer offers a 401(k) with a match, and you also want an IRA. In the IRA vs 401k question, the order for most people is settled: put enough into the 401(k) to collect the full match, then fund an IRA, then go back and fill the 401(k) to its limit. Money beyond that goes to a taxable account.

The order changes if your plan is expensive, if you might leave before the match vests, or if you carry a large rollover IRA from an old job. This piece covers the 2026 limits, the match, fees and investment choice, access before retirement and rollovers. The separate choice between Roth and pre-tax money is in our piece on Roth vs traditional IRA. We are not tax advisers, so check your own position with one before acting.

IRA vs 401k: The Funding Order

First, the match. FINRA notes that many employer plans offer matching contributions up to a preset limit. That money exists only inside the 401(k). No IRA can offer it.

Run an illustration. Suppose your employer adds 50 cents for every dollar you contribute, up to 6% of a $250,000 salary. Contributing $15,000 brings in $7,500 from your employer. That is a 50% return on the day the money goes in, before any investment growth.

Second, the IRA. Once the match is collected, the IRA usually earns the next dollar, for two reasons we cover below: you choose the provider, and you choose the funds. For executives above the Roth income limit, this step means a backdoor Roth, which our Roth vs traditional IRA guide explains.

Third, back to the 401(k). The IRA fills quickly. The 401(k) has far more room, and every dollar in it still grows tax deferred or, in a Roth 401(k), toward tax-free qualified withdrawals.

Fourth, a taxable account. Once both are full, the next dollar goes to an ordinary brokerage account. Our comparison of a Roth IRA vs brokerage account covers what you give up and what you keep there.

Read the Match Rules Before You Count On It

A match you lose when you leave is worth less than it looks. The IRS vesting page says your own salary deferrals are always 100% vested. Employer contributions can follow a schedule instead. Under cliff vesting you own all of it after three years of service. Under graded vesting, ownership can rise by 20% a year to reach 100% in year six. The IRS says amounts that are not vested may be forfeited when you are paid your account balance.

Timing matters too. FINRA notes that a match may be made as infrequently as once a year. If yours is paid in a single annual deposit, leaving a month before it lands can cost you the whole year’s match.

Neither rule changes the order. You still take the match, because the alternative is collecting none of it. They do change how you value a job offer and when you resign. Our breakdown of a compensation package shows where the retirement plan sits in the total.

2026 Contribution Limits

The 401(k) holds far more. For 2026, the IRS sets the employee contribution limit for 401(k), 403(b) and governmental 457 plans, and the federal Thrift Savings Plan, at $24,500. The catch-up for people aged 50 and over is $8,000. For people aged 60 to 63 the catch-up is $11,250 instead.

The same release sets the IRA limit at $7,500 for 2026, with a catch-up of $1,100 for people 50 and over. The IRS contribution limits page adds that this is the total across all your traditional and Roth IRAs, capped at your taxable compensation if that is lower.

Put side by side, a 52-year-old can defer $32,500 through the 401(k) and put $8,600 into IRAs. The 401(k) carries close to four times as much.

High earners have one new rule to plan for. The IRS catch-up page says that starting in 2026, participants in plans with a Roth feature must make catch-up contributions on a Roth basis if their prior-year wages with the plan sponsor were more than $150,000. For an executive over 50 above that line, the catch-up is now Roth money whatever they would have chosen.

The 401(k) also changes the IRA itself. Being covered by a workplace plan limits the traditional IRA deduction from modest incomes upward, which is why the IRA step for most covered executives is a Roth or a backdoor Roth. Our Roth vs traditional IRA piece has the 2026 ranges.

Fees and Investment Choice

Fees are the main reason the IRA comes second in the IRA vs 401k order, ahead of a full 401(k). The Department of Labor’s guide, A Look at 401(k) Plan Fees, gives the example of a $25,000 balance left for 35 years at a 7% average return. With fees and expenses of 0.5%, it grows to $227,000. With fees of 1.5%, it grows to only $163,000. The one-point difference cuts the balance at retirement by 28%.

The same guide sorts plan costs into three groups: plan administration fees for running the plan, investment fees for managing the funds, and individual service fees for options such as a loan. It calls investment fees the largest component of plan fees.

Choice is the other reason. FINRA says employer plans usually offer a set list of investments, and some add a self-directed brokerage window. An IRA lets you pick the provider, so you can choose low-cost index funds if your plan menu lacks them.

Ask for your plan’s fund list and costs before you decide how much goes past the match. If the menu has a cheap broad index fund, the gap with an IRA narrows and filling the 401(k) first becomes reasonable. If every option is an expensive actively managed fund, the IRA earns its place in step two.

Access Before Retirement

The two accounts treat early withdrawals differently, and the differences favour each side in turn. The IRS list of exceptions says withdrawals before 59½ generally carry an additional 10% tax unless an exception applies.

The 401(k) has one exception that matters a great deal to executives who plan to stop early. If you separate from service during or after the year you reach 55, withdrawals from that employer’s plan escape the 10% tax. The IRS says the exception does not apply to IRAs.

The IRA has its own. A qualified first-time home purchase, up to $10,000, and qualified higher education expenses are exceptions for IRAs but not for workplace plans. Both account types allow one emergency withdrawal a year, limited to the lesser of $1,000 or the vested balance over $1,000.

Loans run one way only. FINRA says you can borrow from employer-sponsored plans, but not from any type of IRA.

Required minimum distributions also differ. The IRS RMD FAQs say participants in a workplace plan can delay RMDs until the year they retire, unless they own 5% of the business sponsoring the plan. Owners of traditional, SEP and SIMPLE IRAs must begin at 73.

The Two Accounts Side by Side

	401(k)	IRA
2026 contribution limit	$24,500	$7,500 across all IRAs
Catch-up at 50+	$8,000, or $11,250 at ages 60 to 63	$1,100
Employer match	Available in many plans	None
Investment choice	The plan’s set list, sometimes a brokerage window	Whatever the provider you pick offers
Loans	Allowed in some plans	Not allowed
Penalty-free after leaving a job at 55+	Yes, from that employer’s plan	No
First home and higher education exceptions	No	Yes
RMDs while still working	Can delay unless a 5% owner	Traditional IRAs from 73

The match and the limit put the 401(k) first and last in the IRA vs 401k order. Fees and choice put the IRA in the middle.

Rollovers When You Change Jobs

When you leave, FINRA lists four options for the old 401(k): leave it in the plan, move it to your new employer’s plan if that plan accepts transfers, roll it into an IRA, or take the cash. FINRA warns that cashing out is costly.

The mechanics decide whether a rollover is clean. The IRS rollover page says a direct rollover, paid straight from the plan to the new plan or IRA, has no tax withheld. A distribution paid to you is subject to mandatory 20% withholding, even if you intend to roll it over, and you then have 60 days to deposit the full amount, making up the withheld 20% from other money. The once-a-year limit on IRA-to-IRA rollovers does not apply to plan-to-IRA rollovers or to trustee-to-trustee transfers. Always ask for the direct route.

Where the money lands matters more for executives than the mechanics. A rollover IRA counts in the pro-rata calculation for a backdoor Roth. Charles Schwab explains that the IRS generally considers all your traditional IRA balances together, including rollover IRAs. In Schwab’s example, $93,000 of pre-tax IRA money makes about $6,510 of a $7,000 backdoor conversion taxable. Each conversion also starts its own five-year clock, which our piece on the Roth IRA 5 year rule explains.

An executive who uses the backdoor every year should think twice before rolling a large 401(k) into an IRA. Moving it into the new employer’s plan, if the plan accepts it, keeps the IRA balance at zero and the backdoor clean. It also keeps the age 55 exception open if you later leave that employer at 55 or older.

The IRA wins the rollover when the new employer’s plan is expensive or there is no new plan, when you want to consolidate several old accounts in one place, or when you will not use the backdoor.

When the Order Changes

The standard order bends in a few cases.

No match at all. Without free money in the 401(k), the IRA can go first for its choice and fees, and the 401(k) takes what is left.

A short stay. If you expect to leave before the match vests, the match is worth only what you will keep. Contribute anyway if the plan is cheap, because the tax deferral still counts, but weigh it against the IRA as if the match were smaller.

Early retirement. If you plan to stop at 55, money in that employer’s 401(k) is reachable without the 10% tax. That can justify keeping more in the 401(k) and less in the IRA during your last years at the company.

Self-employment. With no employer plan, the comparison changes completely. Our guide to llc vs s corp covers the structures that decide which plans you can set up for yourself.

How We Would Fund a Year

Take a hypothetical 52-year-old executive on $250,000 with the 50% match up to 6% described above. She sets her 401(k) deferral to collect the full match, $15,000 over the year, and her employer adds $7,500. She then makes an $8,600 backdoor Roth contribution, because her IRA balance is zero. She returns to the 401(k) and raises her contributions to reach $32,500 for the year, with the $8,000 catch-up going in as Roth because her wages last year were above $150,000. Anything she saves after that goes to a brokerage account.

That sequence takes an afternoon to set up, plus one backdoor conversion a year. Write it down with dates. Our guide on short term career goals shows how to make a target like this specific and checkable, and our piece on concrete thinking explains why “fund retirement” stalls and “raise my deferral to 13% on Monday” gets done. Our guide to net worth by age gives a rough benchmark for whether the total is on track.

Your employer shapes all of this. If you are offered a 403(b) instead, our guide to 403b vs 401k compares the two. Moving from one of the big 4 consulting firms to industry is a good moment to check the new plan’s match and vesting before you resign from the old one. A career break to retrain, covered in our piece on what is upskilling, is a year with no workplace plan, and an IRA contribution needs taxable compensation, so check what you will earn that year before counting on one. If you plan to retire abroad, perhaps to one of the countries with best work life balance, ask a cross-border adviser how that country treats US retirement withdrawals.

A new job brings a run of small decisions, from benefits enrolment to the office’s version of the smart casual dress code men wear. Give the enrolment choice a calm hour of its own; our piece on caffeine and anxiety is worth reading before a week like that.

Frequently Asked Questions

Can I contribute to a 401(k) and an IRA in the same year?

Yes. The limits are separate: $24,500 for the 401(k) and $7,500 across your IRAs for 2026, according to the IRS. Being covered by the 401(k) can limit or remove the deduction for a traditional IRA, depending on your income.

Should I roll my old 401(k) into an IRA?

Only if you will not use a backdoor Roth, or the plan is expensive. A rollover IRA counts in the pro-rata calculation and can make most of a backdoor conversion taxable. If your new employer’s plan accepts transfers and has low fees, moving the money there keeps the backdoor clean. Use a direct rollover either way to avoid the 20% withholding.

What happens to my 401(k) match if I leave before it vests?

You may lose it. The IRS says your own deferrals are always fully vested, but employer contributions can follow a cliff schedule of up to three years or a graded one of up to six, and unvested amounts may be forfeited.

In the IRA vs 401k decision, the 401(k) wins on the match and on room, and the IRA wins on choice and cost. The order follows the money: take the match, fill the IRA, then fill the 401(k), and keep any rollover IRA out of the way of a backdoor Roth.
