Can You Have a Roth IRA and a 401(k)? Limits and Income Rules

Yes, you can have a Roth IRA and a 401(k) at the same time, and you can contribute to both in the same tax year. The two accounts sit in separate buckets under the tax code, so maxing out one does not shrink the room in the other. The only real gatekeeper is income: Roth IRAs have eligibility limits that phase out direct contributions once your earnings pass certain thresholds, while 401(k) contributions have no income cap at all.

How Much You Can Put in Each Account for 2026

Because the limits are independent, a worker under 50 could put up to $24,500 into a 401(k) and another $7,500 into a Roth IRA in 2026, for $32,000 in personal retirement contributions.

401(k)

Standard employee deferral limit: $24,500, whether directed to the traditional (pre-tax) or Roth side of the plan.
Catch-up for age 50 and older: an extra $8,000, bringing the total to $32,500.
Enhanced catch-up for ages 60 through 63 under the SECURE 2.0 Act: $11,250 instead of $8,000, for a total of $35,750.

These figures apply per person across every 401(k)-type plan you touch in the year. If you switch jobs and contribute to two different plans, the limit covers your combined deferrals, not each plan separately.¹

Roth IRA

Standard limit: $7,500.
Catch-up for age 50 and older: an extra $1,100, for a total of $8,600.

The $7,500 cap covers all of your traditional and Roth IRAs combined. Put $3,000 into a traditional IRA, and only $4,500 remains for a Roth IRA that year.²

Different Deadlines

401(k) contributions come out of paychecks issued during the calendar year. Once December 31 passes, you cannot add more for that tax year. Roth IRA contributions are different: you can make them any time up to the tax filing deadline (typically April 15 of the following year), which gives you several months after year-end to check your income and decide how much to put in.

The Income Limits That Can Block Your Roth IRA

Anyone with access to a 401(k) can contribute regardless of income. The Roth IRA is stricter. Eligibility phases out based on your Modified Adjusted Gross Income (MAGI). For 2026:¹

Single or head of household: full contribution below $153,000 MAGI, reduced between $153,000 and $168,000, none at $168,000 or above.
Married filing jointly: full contribution below $242,000 MAGI, reduced between $242,000 and $252,000, none at $252,000 or above.

If your MAGI lands inside a phase-out range, an IRS formula calculates your reduced allowance based on where you sit in the window. Going over your permitted amount triggers a 6% excise tax on the excess for every year it stays in the account.³

None of these income rules affect your 401(k). A high earner shut out of direct Roth IRA contributions can still defer the full $24,500 (plus any catch-up) into a workplace plan.

Backdoor Roth if Your Income Is Too High

If you earn above the Roth IRA thresholds, a workaround called a “backdoor Roth” still gets money into a Roth account. The steps: make a nondeductible contribution to a traditional IRA (which has no income limit for contributions), then convert that balance to a Roth IRA. Because you already paid tax on the money and took no deduction going in, the conversion itself is generally not taxable, provided you have no other pre-tax IRA balances complicating the math. The conversion is reported on Form 8606, which tracks nondeductible IRA contributions and calculates the taxable portion of any conversion or distribution.⁴

Watch the Pro-Rata Rule

If you already hold pre-tax money in any traditional, SEP, or SIMPLE IRA, the IRS will not let you convert only the after-tax dollars. It treats all of your traditional IRA money as one combined pool and calculates the taxable share of a conversion proportionally.⁵

Take an example. Suppose you have $92,500 in pre-tax traditional IRA funds and add a $7,500 nondeductible contribution. Your total is $100,000, only 7.5% of which is after-tax money. Roughly 92.5% of any amount you convert becomes taxable income, even if you intended to convert just the $7,500 you contributed. One common fix: roll your pre-tax IRA balances into your employer’s 401(k) plan (if it accepts incoming rollovers) before the conversion, leaving only after-tax money in your traditional IRA.

Why Hold Both Accounts

The core reason to fund a 401(k) and a Roth IRA together is tax diversification: flexibility over how your retirement income gets taxed. A traditional 401(k) uses pre-tax dollars now and taxes withdrawals later as ordinary income. A Roth IRA uses after-tax dollars now and lets you withdraw earnings tax-free in retirement once you meet the qualification rules.

Holding both lets you manage your tax bill year by year in retirement. In a year with a big one-time expense, you can pull from the Roth IRA without lifting your taxable income. In a low-income year, you can take traditional 401(k) distributions at a lower rate. That kind of planning is hard when everything sits in one type of account.

Required Minimum Distributions

A Roth IRA has no required minimum distributions (RMDs) during your lifetime. Traditional 401(k) accounts require taxable withdrawals starting at age 73, rising to age 75 in 2033. A Roth IRA can keep growing tax-free for as long as you live. If your 401(k) offers a designated Roth account (a Roth 401(k)), those funds are also exempt from RMDs while you are alive under the SECURE 2.0 Act, a change that took effect in 2024.⁶

Spousal Roth IRAs When One Spouse Has the 401(k)

Married couples filing jointly get the higher Roth IRA phase-out range and a useful rule for a non-working spouse. Normally you need earned income to contribute to an IRA. On a joint return, a spouse with little or no income can make a full IRA contribution based on the working spouse’s compensation. Each spouse can contribute up to $7,500 (or $8,600 at age 50 or older), as long as the couple’s combined contributions do not exceed their joint taxable compensation.⁷

A household where one spouse works and contributes to a 401(k) can still fund two separate Roth IRAs, one for each spouse, as long as joint income falls below the phase-out. The spousal rule applies whether or not either spouse participates in an employer plan.

If You Contribute Too Much to the Roth IRA

Overcontributing happens most often when income lands in the phase-out range unexpectedly or when someone loses track of contributions across multiple IRAs. You have a few ways to fix it before the penalty hits.

Withdraw the excess and any earnings it generated by the due date of your return (including extensions). Meeting that deadline avoids the 6% penalty. The earnings portion is taxable in the year the contribution was made.²
Recharacterize the contribution by moving it and its earnings to a traditional IRA through a trustee-to-trustee transfer. The contribution is then treated as if it had gone to the traditional IRA from the start. Same deadline, and you must attach a statement explaining the recharacterization to your return.⁴
Apply the excess to the next tax year if you have room, though the 6% penalty still applies for the year the excess existed.

Miss the deadline and leave the excess in the account, and you owe the 6% excise tax for every year it stays there. The penalty is reported on Form 5329 with your return.³
