Money coming out of a Roth 401(k) is entirely tax-free, earnings included, when two conditions are both met: you’ve held a designated Roth account in the plan for at least five years, and you’re either 59½, totally and permanently disabled, or the funds are being paid to a beneficiary after your death. Miss either condition and the withdrawal becomes “non-qualified,” which means the earnings portion gets taxed as ordinary income and, if you’re under 59½, may also carry a 10% early withdrawal penalty. Those are the Roth 401(k) distribution rules in their shortest form. The details below matter because small planning choices, especially around rollovers, can decide whether earnings come out clean or not.
What Counts as a Qualified Distribution
A qualified distribution is the goal. Every dollar, contributions and earnings, leaves the account free of federal income tax and free of the early withdrawal penalty. You get there by clearing two hurdles at the same time.
The first is the five-year rule. The clock starts on January 1 of the tax year you first made a designated Roth contribution to any Roth account in that employer’s plan. A first contribution made in October 2022 means your five-year period began January 1, 2022, and finishes at the end of December 31, 2026. If you do a direct rollover from an old employer’s Roth 401(k) into a new employer’s Roth 401(k), the earlier start date carries over, which can cut years off the wait.
The second hurdle is a triggering event: reaching age 59½, becoming totally and permanently disabled, or death (with the distribution going to your beneficiary). Both boxes checked, the money is yours tax-free.
What Happens When You Withdraw Early
Take money out before you’ve satisfied both conditions and the distribution is non-qualified. This is where the Roth 401(k) parts ways with the Roth IRA in a way that surprises people.
A Roth IRA lets contributions come out first, so you can pull your basis without touching earnings. A Roth 401(k) doesn’t work that way. Every non-qualified withdrawal is treated as a pro-rata mix of contributions and earnings, based on the ratio of your total contributions to your total account balance. Say your Roth 401(k) holds $9,400 in contributions and $600 in earnings and you withdraw $5,000: $4,700 of that comes out as contributions and $300 as earnings. Contributions are always tax-free because you already paid income tax on them. Earnings get added to your gross income and taxed at your ordinary rate. Under 59½, that earnings slice also faces the 10% early withdrawal penalty.
There’s a workaround if you want to reach your basis without touching earnings. Rolling the Roth 401(k) into a Roth IRA first puts the money under the IRA ordering rules, where contributions come out ahead of earnings. The catch is that the Roth IRA has its own separate five-year clock, covered further down.
Exceptions to the 10% Penalty
Several situations let you skip the 10% penalty on a non-qualified withdrawal. The earnings portion is still ordinary income, but the extra penalty falls away. The commonly used exceptions for employer plans:
- Leaving your job during or after the calendar year you turn 55 (age 50 for qualifying public safety employees). This applies only to the plan at the employer you just left, not to old 401(k)s from prior jobs.
- Total and permanent disability, at any age.
- Distributions to a beneficiary after the account owner’s death.
- Substantially equal periodic payments over your life expectancy, sometimes called 72(t) payments.
- Unreimbursed medical expenses above 7.5% of your adjusted gross income.
- Payments to a former spouse under a qualified domestic relations order (QDRO).
- Certain distributions to military reservists called to active duty.
SECURE 2.0 added more, effective for distributions after December 31, 2023:
- Emergency personal expenses: one withdrawal per calendar year, limited to the lesser of $1,000 or your vested balance above $1,000. Fail to repay it within three years and you can’t take another emergency withdrawal until the repayment period ends.
- Domestic abuse victims: the lesser of $10,000 (indexed for inflation) or 50% of the vested account balance.
- Federally declared disasters: up to $22,000 for individuals with economic loss from a qualifying disaster.
- Birth or adoption expenses: up to $5,000 per child.
These waive the 10% penalty only. On a Roth 401(k), the contribution portion of any distribution is already tax-free, and the earnings portion of a non-qualified distribution is still taxable income.
No More Required Minimum Distributions
Roth 401(k) accounts used to be subject to required minimum distributions during the owner’s lifetime, which cut against the whole idea of tax-free growth. SECURE 2.0 eliminated RMDs from designated Roth accounts in employer plans starting with the 2024 tax year. Your Roth 401(k) can now compound tax-free for your entire lifetime with no forced withdrawals.
Two boundaries to keep in mind. Any outstanding RMD obligation from a year before 2024 still has to be satisfied. And traditional pre-tax 401(k) balances in the same plan remain on their normal RMD schedule: age 73 for people born between 1951 and 1959, and age 75 for those born in 1960 or later.
Rolling Over and the Five-Year Clock
Where you send your Roth 401(k) money at job change decides which five-year clock governs your earnings, and getting this wrong can create a tax bill on withdrawals you assumed were qualified.
Into Another Roth 401(k)
A direct rollover from one employer’s Roth 401(k) to another’s uses whichever plan had the earlier contribution start date. A first Roth 401(k) contribution in 2020, rolled into a brand-new Roth 401(k) at a new job in 2026, keeps the 2020 start date. The five-year requirement is already behind you.
Into a Roth IRA
Rolling into a Roth IRA is popular because of the wider investment menu and the absence of RMDs. But the Roth IRA runs on its own separate five-year clock, and time spent in the Roth 401(k) does not count toward it. If you’ve never funded a Roth IRA before, a fresh five-year clock starts on January 1 of the year you open the account and take the rollover.
The workaround is straightforward: the Roth IRA five-year clock is universal across all of your Roth IRAs. A first Roth IRA contribution in 2019 means that clock has long since run. Rolling Roth 401(k) funds into that existing Roth IRA in 2026 inherits the satisfied five-year period, and if you’re 59½ or otherwise qualify, earnings are immediately eligible for tax-free treatment. Opening and funding a Roth IRA with even a small amount well before you expect to move a Roth 401(k) is one of the simpler planning moves available.
Rules for Inherited Roth 401(k)s
What happens after the account owner dies turns almost entirely on whether the beneficiary is the surviving spouse.
Surviving Spouse
A surviving spouse has the widest set of choices. You can roll the inherited Roth 401(k) into your own Roth IRA or your own Roth 401(k) and treat the funds as if they’d always been yours. You can also leave the money in the deceased spouse’s plan, and under a SECURE 2.0 provision effective in 2024, elect to be treated as the deceased employee for RMD purposes. Since Roth 401(k) accounts no longer carry RMDs for original owners, that election lets the balance keep compounding.
A spouse who moves the funds to an inherited IRA can take withdrawals at any time without the 10% early withdrawal penalty, regardless of age. Watch this trap, though: if you’re under 59½ and roll the inherited Roth 401(k) into your own retirement account rather than an inherited IRA, later withdrawals of earnings before you turn 59½ could trigger the early withdrawal penalty.
Non-Spouse Beneficiaries
Most non-spouse beneficiaries must empty the inherited account by December 31 of the tenth year after the original owner’s death. This is the 10-year rule from the SECURE Act. You can withdraw on any schedule within that window: lump sum in year one, gradual annual withdrawals, or one payout in year ten.
A narrow group of “eligible designated beneficiaries” can stretch distributions over their own life expectancy instead: minor children of the deceased (until they reach the age of majority), individuals who are disabled or chronically ill, and beneficiaries not more than 10 years younger than the deceased. Once a minor child reaches adulthood, the 10-year rule takes over for whatever remains.
For every beneficiary, tax treatment still hinges on whether the original owner’s five-year clock had run before death. If it had, distributions to beneficiaries come out fully tax-free. If the owner died before the five-year period was satisfied, the earnings portion is taxable income to the beneficiary until that original clock finishes running.
