The Roth 401k withdrawal rules turn on one question: is the distribution “qualified” or not? A qualified distribution comes out entirely tax-free, while a non-qualified one is split proportionally between your contributions and your earnings, with the earnings taxed and possibly penalized. This guide covers the employer-plan mechanics that govern a designated Roth account, including the separate five-year clock, the age 59.5 threshold, the 10% early-withdrawal penalty, and the 2024 elimination of lifetime required minimum distributions.
A Roth 401(k) distribution is fully tax-free when it is “qualified,” meaning the account has met a five-tax-year period of participation and the owner is at least age 59.5 (or the distribution follows death or disability). Contributions can always be recovered, but a non-qualified withdrawal is prorated between basis and earnings, and the earnings portion may face tax plus a 10% penalty (Source: IRS Pub 575, 2025).
Roth 401k withdrawal rules: qualified vs non-qualified distributions
Every Roth 401(k) withdrawal falls into one of two categories, and the category decides the tax result. A “qualified distribution” from a designated Roth account is excluded from gross income, so both the contributions and the investment earnings come out tax-free (Source: IRS Pub 575, 2025). Anything that is not qualified is a non-qualified distribution and is treated differently.

The IRS uses a two-prong test for a qualified distribution. First, the account must satisfy a five-tax-year period of participation. Second, the distribution must be made on or after the date the owner reaches age 59.5, or after death (to a beneficiary or estate), or because the owner is disabled (Source: IRS Pub 575, 2025). Both prongs must be met at the same time.
A “designated Roth account” is the IRS term for the Roth option inside an employer plan, which can be a Roth 401(k), Roth 403(b), or governmental Roth 457(b). The rules described here apply to that employer-plan account, which is not the same thing as a Roth IRA, though the two interact when money moves between them.
FAQ: What makes a Roth 401(k) distribution “qualified”?
A distribution is qualified when the account has completed a five-tax-year period of participation and one triggering event has occurred: the owner reaches age 59.5, becomes disabled, or dies (Source: IRS Pub 575, 2025). Meeting only the age test or only the five-year test is not enough. Both conditions must be satisfied before the earnings can be withdrawn free of income tax.
The 5-year rule and when the clock starts
The five-year clock for a Roth 401(k) begins on the first day of the first tax year for which you made a designated Roth contribution to that specific plan, and it ends when five consecutive tax years have passed (Source: IRS Retirement Plans FAQs on Designated Roth Accounts). The clock is tied to the plan, not to your age and not to any Roth IRA you may hold.
The IRS gives a concrete example: if your first designated Roth contribution is for tax year 2025, the earliest year in which a qualified distribution can be made is 2030 (Source: IRS Pub 575, 2025). Because the count is by tax year rather than by calendar day, a contribution made late in 2025 still credits the entire 2025 tax year toward the five.
The clock is plan-specific, which matters when you change employers. Each Roth 401(k) generally carries its own five-year period, so a long clock at one employer does not automatically transfer to a new employer’s plan unless the balance is rolled directly from one Roth 401(k) into the other, which can carry the older start date forward (Source: IRS Retirement Plans FAQs on Designated Roth Accounts).
FAQ: When does the Roth 401(k) five-year clock start?
It starts on the first day of the first tax year for which you made any designated Roth contribution to that plan (Source: IRS Retirement Plans FAQs on Designated Roth Accounts). A contribution for 2025 sets a start of January 1, 2025, so the five-year period is complete at the end of 2029 and qualified distributions may begin in 2030 (Source: IRS Pub 575, 2025).
The age 59.5 threshold and the 10% early-withdrawal penalty
Age 59.5 is the second prong of the qualified-distribution test, and it is also the line the 10% early-distribution additional tax draws. A 10% additional tax applies to the portion of an early distribution that is includible in gross income when received before age 59.5 from a qualified plan other than an IRA (Source: IRS Topic No. 558). On a Roth 401(k), that generally means the penalty hits only the taxable earnings portion.
Because your contributions were already made with after-tax dollars, the return-of-contributions portion of any withdrawal is not taxed again and is not subject to the 10% penalty (Source: IRS Pub 575, 2025). The tax and penalty exposure on an early, non-qualified withdrawal is limited to the earnings that come out with it.
Several exceptions waive the 10% penalty on the taxable portion even before age 59.5. The list has grown under the SECURE 2.0 Act, and it is often scattered across sources, so the table below consolidates the current set.
| Penalty exception | Notes (Source: IRS Topic No. 558) |
|---|---|
| Total and permanent disability | Also satisfies a qualified-distribution trigger |
| Death | Distributions to a beneficiary or estate |
| Separation from service at age 55+ | The “Rule of 55”; age 50 (or 25 years of service) for qualified public-safety workers under IRC 72(t)(10) (Source: IRS Topic No. 558) |
| Substantially equal periodic payments | SEPP under IRC 72(t)(2)(A)(iv) (Source: IRS Topic No. 558) |
| Unreimbursed medical expenses over 7.5% of AGI | To the extent above the threshold |
| Qualified birth or adoption | Up to $5,000 per child |
| Qualified domestic relations order (QDRO) | Payment to an alternate payee |
| IRS levy or terminal illness | Levy on the account; terminal-illness distributions |
| Domestic-abuse victim; emergency personal expense | Both added by SECURE 2.0, for distributions after 12/31/2023 |
| Qualified reservist; federally declared disaster | Called to active duty; disaster-relief distributions |
An exception to the penalty is not the same as making a distribution tax-free. If the account is not yet qualified, the earnings that come out under one of these exceptions are still generally taxed as ordinary income; the exception only removes the extra 10% (Source: IRS Topic No. 558).
The pro-rata rule for non-qualified withdrawals
A non-qualified Roth 401(k) distribution is allocated pro-rata between your basis (contributions) and your earnings. The basis portion is found by multiplying the distribution by the ratio of your designated Roth contributions to the total account balance, and the rest is taxable earnings (Source: IRS Retirement Plans FAQs on Designated Roth Accounts). Every dollar you pull carries a slice of earnings with it.
This is where the employer-plan rules diverge from Roth IRA rules, and it is a common point of confusion. A Roth IRA uses ordering rules: regular contributions come out first, then conversions, and earnings come out last, so contributions can be reached tax- and penalty-free before any earnings are touched (Source: IRC 408A(d)(4); IRS Pub 590-B, 2025). A Roth 401(k) does not offer that “contributions first” treatment for non-qualified distributions.
A worked dollar example
Suppose a Roth 401(k) holds $20,000, made up of $18,000 in contributions and $2,000 in earnings, and the owner takes a $20,000 non-qualified distribution. The basis ratio is $18,000 divided by $20,000, or 90%. That makes $18,000 a tax-free return of contributions and $2,000 taxable earnings; if the owner is under 59.5, the 10% penalty generally applies to that $2,000 (Source: IRS Retirement Plans FAQs on Designated Roth Accounts).
The IRS uses the same math in its own example: a $5,000 non-qualified distribution from an account with $9,400 in contributions and $600 in earnings comes out as $4,700 nontaxable and $300 taxable (Source: IRS Retirement Plans FAQs on Designated Roth Accounts). The proportion of earnings in the account is the proportion of earnings in the check.
| Account type | How a non-qualified withdrawal is treated |
|---|---|
| Roth 401(k) (designated Roth account) | Prorated: each dollar is part basis, part earnings by account ratio (Source: IRS Designated Roth FAQs) |
| Roth IRA | Ordered: contributions first, conversions next, earnings last (Source: IRC 408A(d)(4); IRS Pub 590-B, 2025) |
No lifetime RMDs for Roth 401(k)s since 2024
As of 2024, a Roth 401(k) is not subject to required minimum distributions during the owner’s lifetime. SECURE 2.0 Act Section 325 amended the tax code (adding IRC 402A(d)(5)) so the lifetime RMD rules do not apply to a designated Roth account, effective for tax years beginning after December 31, 2023 (Source: IRS Notice 2024-2; IRS RMD FAQs). This aligns Roth 401(k)s with Roth IRAs, which never had lifetime RMDs.
This point is a live source of stale information. Some ranking pages still imply that Roth 401(k)s face RMDs at 73 or bury the change; the current and correct rule is that no lifetime RMD is required from the original owner’s Roth 401(k) as of 2024 (Source: IRS RMD FAQs). One narrow transition detail: the relief does not apply to a 2023 RMD that was permitted to be paid by April 1, 2024 (Source: IRS Notice 2024-2).
For contrast, traditional (pre-tax) retirement accounts still require RMDs. The general required beginning age is 73 under SECURE 2.0, rising to 75 for those born in 1960 or later (Source: IRS RMD FAQs). Someone who reached 73 in 2024 has a first traditional-account RMD due by April 1, 2025 (Source: IRS RMD FAQs). For a fuller treatment of the timing, see the Q3 Advisors overview of required minimum distributions for 2026.
One caveat applies after death. The lifetime relief is for the original owner only; beneficiaries who inherit a designated Roth account remain subject to the post-death RMD rules (Source: IRS RMD FAQs).
FAQ: Do Roth 401(k)s still face RMDs at 73?
No. Since 2024, Roth 401(k)s are exempt from lifetime RMDs under SECURE 2.0 Section 325, which added IRC 402A(d)(5) effective for tax years after December 31, 2023 (Source: IRS Notice 2024-2). The age-73 RMD rule applies to traditional pre-tax accounts, not to a Roth 401(k) during the owner’s lifetime. Beneficiaries who inherit the account, however, still follow post-death RMD rules (Source: IRS RMD FAQs).
Rolling a Roth 401(k) over: the two five-year clocks
Moving a Roth 401(k) into another Roth account is generally a tax- and penalty-free event, but the rollover can change which five-year clock governs your earnings. A direct rollover to a Roth IRA or to another employer’s Roth 401(k) is not a taxable distribution (Source: IRS Pub 575, 2025). The complication is timing, and it is where two separate clocks come into play.
There is the Roth 401(k) plan clock (the five-tax-year period inside the employer plan) and the Roth IRA clock (the five-year period for the receiving IRA). When you roll a Roth 401(k) into a Roth IRA, the earnings become governed by the Roth IRA’s own five-year clock, which runs from your first-ever Roth IRA contribution (Source: IRC 408A(d); IRS Pub 590-B, 2025).
That interaction cuts two ways. Rolling a long-held Roth 401(k) into a brand-new Roth IRA can restart the earnings clock, because the receiving IRA has its own start date; but if you have held any Roth IRA for five or more years, its clock may already be satisfied. One approach some savers use is to open a Roth IRA early, even with a small amount, so the IRA clock is well underway before a later rollover. A rollover to a Roth IRA can also end lifetime RMDs on those funds, since Roth IRAs have never required them (Source: IRS RMD FAQs).
Weighing a rollover often depends on other retirement-tax factors, such as the Social Security tax torpedo and Medicare IRMAA brackets, because taxable withdrawals can raise the income figures those rules use.
FAQ: Does a rollover restart my five-year clock?
It can. Rolling a Roth 401(k) into a Roth IRA shifts the earnings to the Roth IRA’s own five-year clock, which starts from your first Roth IRA contribution (Source: IRC 408A(d); IRS Pub 590-B, 2025). If that IRA is new, the earnings clock effectively restarts; if you have held a Roth IRA for five or more years, the clock may already be met.
The Rule of 55 and loans from a Roth 401(k)
The Rule of 55 lets you take penalty-free distributions from an employer plan if you separate from service in or after the year you turn 55 (Source: IRS Topic No. 558). It waives the 10% early-distribution tax, but it does not make an unqualified account qualified, so any earnings that come out are generally still taxed as ordinary income if the five-year and age-59.5 tests are not both met.
A loan is a different tool that avoids a distribution entirely. Employer plans that allow loans generally permit borrowing up to the lesser of 50% of your vested balance or $50,000, typically repaid within five years with at least quarterly payments (Source: IRS Retirement Topics – Plan Loans, IRC 72(p)). A repaid loan is not a taxable distribution, so it does not trigger the pro-rata earnings tax, though a defaulted loan can be treated as a distribution.
FAQ: Can the Rule of 55 make my earnings tax-free?
No. The Rule of 55 only waives the 10% early-distribution penalty for someone who separates from service at 55 or later (Source: IRS Topic No. 558). If the Roth 401(k) is not yet a qualified account (five-year period plus age 59.5), the earnings portion of a distribution is generally still taxable as ordinary income even though the penalty is removed.
2026 contribution limits and Roth 401(k) vs Roth IRA
For 2026, the employee elective deferral limit for a 401(k) is $24,500, with a $8,000 catch-up for those age 50 and older and a higher $11,250 “super catch-up” for ages 60 through 63 (Source: IRS Notice 2025-67). The Roth IRA contribution limit for 2026 is $7,500, with a $1,100 catch-up at 50 and older (Source: IRS Notice 2025-67). Contribution capacity is one of the clearest differences between the two account types.
| Feature (2026) | Roth 401(k) | Roth IRA |
|---|---|---|
| Employee/annual limit | $24,500 deferral (Source: IRS Notice 2025-67) | $7,500 (Source: IRS Notice 2025-67) |
| Catch-up (age 50+) | $8,000; $11,250 at ages 60-63 (Source: IRS Notice 2025-67) | $1,100 (Source: IRS Notice 2025-67) |
| Lifetime RMDs | None since 2024 (Source: IRS Notice 2024-2) | None (Source: IRS RMD FAQs) |
| Non-qualified withdrawal order | Prorated basis + earnings (Source: IRS Designated Roth FAQs) | Contributions first (Source: IRC 408A(d)(4)) |
| Income limit to contribute | None | Phases out by MAGI: $153,000 to $168,000 (single), $242,000 to $252,000 (married filing jointly) for 2026 (Source: IRS Notice 2025-67) |

Frequently asked questions
Can you roll your 401(k) into a Roth 401(k)?
Many plans permit an in-plan Roth rollover, converting pre-tax 401(k) money into the Roth 401(k) side of the same plan. The converted amount is generally taxable as ordinary income in the year of conversion, but future qualified withdrawals can be tax-free (Source: IRS Pub 575, 2025). Availability depends on your specific plan document, so plan terms should be checked directly.
Can you take a loan from your Roth 401(k)?
If your plan allows loans, you can generally borrow up to the lesser of 50% of your vested balance or $50,000, typically repaid within five years with at least quarterly payments (Source: IRS Retirement Topics – Plan Loans, IRC 72(p)). A loan that is repaid on schedule is not a taxable distribution, so it avoids the pro-rata earnings tax. A defaulted loan, however, can be treated as a taxable distribution.
Do Roth 401(k)s have RMDs?
Not during the owner’s lifetime, as of 2024. SECURE 2.0 Section 325 removed lifetime RMDs from designated Roth accounts for tax years after December 31, 2023 (Source: IRS Notice 2024-2). The age-73 RMD rule applies to traditional pre-tax accounts. Beneficiaries who inherit a Roth 401(k) still follow post-death RMD rules (Source: IRS RMD FAQs).
Are Roth 401(k) rollovers withdrawable immediately?
Not automatically tax-free. Rolling into a Roth IRA moves earnings under the Roth IRA’s own five-year clock, and earnings withdrawn before that clock and age 59.5 are met can be taxable (Source: IRS Pub 590-B, 2025). Rolled amounts that represent your own contributions may be reachable under Roth IRA ordering rules, but earnings generally are not immediate (Source: IRC 408A(d)(4)).
When can I withdraw money from my Roth 401(k) penalty-free?
Earnings come out penalty-free once the distribution is qualified: a five-tax-year period is complete and you are at least 59.5, or the distribution follows disability or death (Source: IRS Pub 575, 2025). Before that, several exceptions can waive the 10% penalty, including the Rule of 55 and disability, though earnings may still be taxable (Source: IRS Topic No. 558).
What happens to my Roth 401(k) if I change jobs?
You generally can leave it in the old plan if allowed, roll it directly into your new employer’s Roth 401(k), or roll it into a Roth IRA (Source: IRS Pub 575, 2025). A direct rollover is not a taxable event. Note that a rollover to a Roth IRA can shift earnings to the IRA’s own five-year clock (Source: IRS Pub 590-B, 2025).
Can I convert my traditional 401(k) to a Roth 401(k)?
If your plan offers in-plan Roth rollovers, you can convert eligible pre-tax 401(k) balances to the Roth side of the same plan. The converted amount is generally taxable in the conversion year, and later qualified distributions can be tax-free (Source: IRS Pub 575, 2025). Whether this is available depends entirely on your plan document.
What is the difference between a Roth 401(k) and a Roth IRA?
A Roth 401(k) is an employer-plan designated Roth account with a higher 2026 deferral limit of $24,500 and no income limit to contribute, while a Roth IRA has a $7,500 limit and income-based eligibility phaseouts (single MAGI $153,000 to $168,000; married filing jointly $242,000 to $252,000 for 2026) (Source: IRS Notice 2025-67). Both are free of lifetime RMDs, but non-qualified Roth 401(k) withdrawals are prorated, whereas Roth IRAs return contributions first (Source: IRC 408A(d)(4)).
