Can You Have Both a 401(k) and a Roth IRA? (2026)

Last updated: 3 November 2026. All figures are the confirmed 2026 limits from IRS Notice 2025-67.

If you already contribute to a 401(k) at work, you may wonder whether a Roth IRA is still on the table — or whether having one account cancels out the other. The answer is simple: yes, you can have both a 401(k) and a Roth IRA, and you can contribute to both in the same year. The IRS treats them as two separate retirement-saving systems, each with its own annual limit.

A worker under 50 can put up to $24,500 into a 401(k) and up to $7,500 into a Roth IRA in 2026 — a combined $32,000 in tax-advantaged savings. A few rules decide how much of that room you can actually use, especially the Roth IRA's income limits. This guide covers the 2026 numbers, the funding order that usually works best, and the mistakes that cost people money.

The Short Answer: Yes — Two Separate Systems, Two Separate Limits

A 401(k) is a workplace plan: your employer offers it, contributions come out of your paycheck, and the IRS sets one limit for it. A Roth IRA is an individual account you open yourself at a brokerage, with a completely separate limit. Contributing to one does not reduce your room in the other.

There is one shared limit inside each system. Your traditional 401(k) and Roth 401(k) contributions together cannot exceed $24,500 — splitting between them buys no extra room. Likewise, your traditional IRA and Roth IRA contributions together cannot exceed $7,500. The two systems stay independent; the sub-accounts inside each system share a ceiling.

Employer matching contributions do not count against your $24,500 employee limit. The match sits on top, inside the overall $72,000 total-additions limit for 2026. If your employer matches 4% of your pay, that money is extra — it never eats into your own contribution room.

The 2026 Limits Side by Side

2026 limit	401(k)	Roth IRA
Base contribution (under 50)	$24,500	$7,500
Catch-up (age 50+)	+$8,000 (total $32,500)	+$1,100 (total $8,600)
Super catch-up (ages 60–63)	+$11,250 (total $35,750)	—
Income limit	None	Phases out $153,000–$168,000 (single)
Employer match	Often, yes	Never

One 2026 change: if you earned more than $150,000 from your employer in 2025, any 401(k) catch-up contribution in 2026 must go into the Roth side of the plan instead of the pre-tax side. It does not change how much you can contribute — only where the catch-up dollars land.

Worked Example: How Much Can You Actually Save?

Meet Maya, 32, earning $78,000 a year. Her employer matches 50 cents for every dollar she puts into her 401(k), up to 6% of her pay.

Maya contributes 6% of her salary — $4,680 — to her 401(k), capturing the full employer match of $2,340. Then she opens a Roth IRA and contributes $500 a month, or $6,000 for the year. Finally, she raises her 401(k) with what is left — another $300 a month, or $3,600.

Her totals: $8,280 into her 401(k), $2,340 in employer matching, and $6,000 into her Roth IRA — $16,620 of retirement saving on a $78,000 salary, without maxing out either account. The Roth IRA money grows tax-free and comes out tax-free in retirement, while the 401(k) money gives her an upfront tax break.

The One Rule That Can Block Your Roth IRA: Income Limits

The 401(k) has no income limit. The Roth IRA is different: for 2026, your ability to contribute directly phases out based on modified adjusted gross income (MAGI).

Filing status	Full $7,500	Partial	None
Single / head of household	Below $153,000	$153,000–$168,000	$168,000+
Married filing jointly	Below $242,000	$242,000–$252,000	$252,000+
Married filing separately	—	$0–$10,000	$10,000+

Pre-tax 401(k) contributions actually help here: they lower your MAGI, which can keep you under the Roth IRA threshold. A single filer earning $160,000 who defers $10,000 into a traditional 401(k) brings MAGI down to $150,000 — back under the $153,000 line for a full Roth IRA contribution.

There is a related trap with a traditional IRA. If you are covered by a workplace plan, its tax deduction phases out too — for 2026, between $81,000 and $91,000 of MAGI for single filers, and $129,000 to $149,000 for married couples filing jointly. Above those ranges the contribution is not deductible, which is why a Roth IRA is usually the better second account once you already have a 401(k). Source: IRS Notice 2025-67.

What Order Should You Fund Them In?

There is no IRS rule about the order, but most planners suggest the same sequence:

1. Contribute enough to your 401(k) to get the full employer match. A match is an instant, guaranteed return you cannot get anywhere else. If your employer matches 100% of the first 3% of your pay, that is a 100% return before any investment growth.

2. Fund your Roth IRA next, up to $7,500. A Roth IRA usually offers far more investment choices than a workplace plan, often with lower fees, and every dollar of growth comes out tax-free in retirement. See our guide to Roth IRA vs 401(k): which to max out first.

3. Go back to your 401(k) with anything left over. Once the Roth IRA is full, raise your 401(k) contributions toward $24,500. The choice between pre-tax and Roth 401(k) contributions depends on your tax bracket today versus the one you expect in retirement — our tax brackets explained guide can help you compare.

If your employer offers no match, the order flips: start with the Roth IRA, then use the 401(k) for anything beyond $7,500. And if you are 60 to 63, remember the 401(k) super catch-up of $11,250 for 2026 — an extra $3,250 over the standard catch-up, available only in those four years.

5 Mistakes to Avoid When You Hold Both

1. Thinking the limits are shared. The most common misunderstanding is that $24,500 is a combined cap. It is not — the 401(k) and IRA limits are separate, and maxing out one leaves the other untouched.

2. Forgetting the IRA limit is combined. The reverse error is just as costly: $7,500 is the total across all your IRAs. Contributing $7,500 to a Roth IRA and another $7,500 to a traditional IRA in the same year is a $7,500 excess contribution, hit with a 6% penalty every year until it is fixed.

3. Skipping the match to fund the Roth IRA first. A Roth IRA is a great account, but no account beats a 100% employer match. Capture the match before a single dollar goes to the IRA.

4. Ignoring the income phase-out. If your MAGI lands inside the $153,000–$168,000 single range (or $242,000–$252,000 joint), your allowed Roth IRA contribution shrinks. Contributing the full $7,500 anyway triggers the same 6% excess-contribution penalty.

5. Confusing a Roth 401(k) with a Roth IRA. They share the word "Roth" and the tax-free withdrawal rule, but a Roth 401(k) lives inside your employer plan, has no income limit, and shares the $24,500 deferral cap. A Roth IRA is yours alone, has its own $7,500 cap, and phases out by income. Our full 2026 401(k) contribution limits guide breaks down every cap and catch-up.

What If You Earn Too Much for a Roth IRA?

Above the phase-out range, direct Roth IRA contributions are off the table — but the 401(k) is not. Because a Roth 401(k) has no income limit, many high earners simply direct more of their 401(k) deferrals to the Roth side of the plan: pay tax now in exchange for tax-free withdrawals later.

Another route is the backdoor Roth IRA: make a non-deductible contribution to a traditional IRA, then convert it to a Roth IRA. Conversions have no income limit. But beware the pro-rata rule — if you already hold pre-tax money in any traditional IRA, part of the conversion gets taxed. One workaround is to roll pre-tax IRA money into your current employer's 401(k) first, if the plan accepts incoming rollovers. Get this right before you move money.

Frequently Asked Questions

Can you have both a 401(k) and a Roth IRA at the same time?

Yes. The IRS allows you to participate in an employer's 401(k) and contribute to a Roth IRA in the same tax year, as long as you meet each account's own rules. The limits are separate: $24,500 for the 401(k) and $7,500 for the IRA in 2026 (under age 50).

How much can you contribute to a 401(k) and a Roth IRA in 2026?

Under age 50, up to $24,500 in employee deferrals to a 401(k) plus up to $7,500 across your IRAs — $32,000 combined. At age 50 or older, the totals rise to $32,500 and $8,600, or $41,100 combined. Employer matching sits on top of the $24,500 and does not reduce your room.

Can you max out both a 401(k) and a Roth IRA?

Yes, if your income allows it. There is no rule against maxing out both in the same year. The only blocker is the Roth IRA income phase-out: for 2026, direct contributions phase out between $153,000 and $168,000 of MAGI for single filers and $242,000 to $252,000 for married couples filing jointly.

Does contributing to a 401(k) reduce your Roth IRA limit?

No. The limits are entirely separate. Pre-tax 401(k) contributions lower your MAGI, which can help you stay under the Roth IRA income phase-out — so a 401(k) can actually make a Roth IRA contribution easier, not harder.

Should I fund my 401(k) or Roth IRA first?

Fund the 401(k) up to the full employer match first, then the Roth IRA up to $7,500, then go back to the 401(k) with anything left over. If your employer offers no match, start with the Roth IRA instead. The match is the only step that is genuinely free money, so it always comes first.
