Roth 401(k) Five-Year Rule: Clocks, Rollovers, and SECURE 2.0

The Roth 401(k) five-year rule is what stands between you and tax-free earnings: your after-tax contributions always come back to you untaxed, but the growth on those contributions is only tax-free once the plan’s five-year holding period has finished and you’ve hit a qualifying event such as reaching age 59½, becoming disabled, or dying. Both pieces have to be true at the same time. Miss either one and the earnings portion of your withdrawal is taxable, and often penalized on top.

When the Five-Year Clock Starts

The clock begins on January 1 of the tax year you make your first Roth contribution to the plan. Start contributing in November 2025 and the IRS treats the clock as having started on January 1, 2025. Your five consecutive tax years run 2025 through 2029, and earnings become eligible for tax-free treatment starting January 1, 2030.¹

Each employer’s plan carries its own independent clock. A Roth 401(k) at your current job and one at a spouse’s employer are separate timelines. Leave a job, start contributing to a new employer’s Roth 401(k) without rolling anything over, and the new plan starts fresh.¹

Within a single plan, the clock never resets. Drain the account to zero and start contributing again years later, and the original start date still governs.¹

In-Plan Roth Conversions

If your plan lets you convert pre-tax 401(k) money into your Roth 401(k) account, the converted dollars ride on the same clock that started with your first Roth contribution to that plan. The clock doesn’t restart with each conversion. This is different from Roth IRAs, where each conversion carries its own separate five-year waiting period for penalty purposes. Inside a Roth 401(k), one plan-level clock covers every Roth dollar in the account.¹

What Makes a Distribution Qualified

A qualified distribution is the combination that gets the entire withdrawal, earnings included, out tax-free and penalty-free. Two conditions have to line up at the same time: the five-year clock must be finished, and you must meet one of three triggering events.²

Reaching age 59½, the most common trigger.
Becoming disabled under the federal definition.
Death, with distributions going to your beneficiaries.

Note what’s not on the list: the first-time homebuyer exception that applies to Roth IRAs is not available for a Roth 401(k). You cannot pull earnings from a Roth 401(k) tax- and penalty-free to buy a home, even if the five-year requirement is met.³

Both pieces of the test have to be present. Turn 59½ but have only held the account three years, and you don’t get tax-free earnings. Hold the account eight years but you’re 52 and healthy, and you don’t either. Miss one and you have a non-qualified distribution.

What Happens When You Take Money Out Early

Here’s where Roth 401(k) accounts part company from Roth IRAs. With a Roth IRA, contributions come out first and earnings last, so you can often withdraw without touching taxable earnings. A Roth 401(k) doesn’t work that way. Every non-qualified distribution contains a proportional mix of contributions and earnings.

The IRS applies a pro-rata formula. Divide your total contributions (your basis) by your total account balance; that fraction of any distribution comes out tax-free, and the rest is treated as earnings and taxed as ordinary income.⁴ If you’re under 59½ and no penalty exception applies, the earnings portion also gets hit with the 10% early distribution penalty.³

You cannot selectively withdraw just your contributions from a Roth 401(k) to keep earnings from being taxed. If you need that flexibility before the five-year clock has run, rolling into a Roth IRA first can give you access to the more favorable ordering rules, though that step brings its own five-year complications, covered below.

The Age 55 Separation Exception

Separate from service during or after the year you turn 55 and the 10% early withdrawal penalty doesn’t apply to distributions from that employer’s plan. For public safety employees, the age threshold drops to 50.³

The trap: avoiding the penalty is not the same as getting a qualified distribution. Leave your job at 56 and take money from a Roth 401(k) you’ve held for only three years, and you skip the 10% penalty on earnings but still owe ordinary income tax on them. The penalty exception and the five-year rule operate independently.

How Rollovers Affect the Clock

Rollovers are where the five-year rule gets genuinely tricky. The rules differ depending on where the money lands, and getting it wrong can add years to the wait.

Roth 401(k) to Another Roth 401(k)

A direct rollover from one employer’s Roth 401(k) to another employer’s Roth 401(k) uses the earlier start date. If the old plan’s clock started in 2022 and you roll directly into a new employer’s plan in 2026, the new plan inherits the 2022 date. The statute says the nonexclusion period begins with the first tax year you made a Roth contribution to whichever designated Roth account is older.⁵ If you already have a Roth account in the receiving plan with a longer history, that older date governs.¹

One catch: not every plan accepts incoming Roth 401(k) rollovers. Confirm with both plan administrators before starting.

Roth 401(k) to Roth IRA

Rolling into a Roth IRA introduces a separate clock. The Roth IRA and Roth 401(k) five-year periods are determined independently.⁶

If you already own a Roth IRA you’ve held for at least five years, the rolled-over funds inherit that existing clock. If you don’t already have a Roth IRA, the rollover creates one and a new five-year clock starts in the rollover year. The time you accumulated in the employer plan counts for nothing toward the Roth IRA timeline. Someone who held a Roth 401(k) for a decade could still face a fresh five-year wait after rolling into a brand-new Roth IRA.⁶

The practical move: if you might ever roll a Roth 401(k) into a Roth IRA, open a Roth IRA and fund it with even a small amount as early as possible. That starts the IRA clock, so when the rollover eventually happens, the five-year requirement is already behind you.

SECURE 2.0 Changes That Interact With the Rule

No More Lifetime RMDs for Roth 401(k)s

Before SECURE 2.0, Roth 401(k) accounts required minimum distributions starting at age 73 even though Roth IRAs did not. That inconsistency pushed many account holders to roll into a Roth IRA just to avoid mandatory withdrawals. That reason is gone. Roth 401(k) accounts no longer require distributions while the account owner is alive.⁷ Fewer people now have to trigger a Roth IRA rollover clock reset for RMD reasons alone.

Mandatory Roth Treatment for High-Earner Catch-Ups

Starting in 2026, employees who earned $150,000 or more in FICA wages the prior year must make their catch-up contributions on a Roth basis. Higher earners who previously made only pre-tax 401(k) contributions will end up with a designated Roth account whether they planned on one or not. If that’s you, your five-year clock starts with that first mandatory Roth catch-up, so watch the timing if you’re close to retirement.

Employer Roth Matching

SECURE 2.0 also allows employers to designate matching and nonelective contributions as Roth. Unlike your own Roth contributions, which have already been taxed through payroll, employer Roth contributions appear as taxable income on Form 1099-R for the year. No payroll taxes are withheld on those amounts, which can create a surprise tax bill if you don’t adjust withholding. Employer Roth contributions go into your designated Roth account and ride on the same plan-level five-year clock as your own contributions.

Inherited Roth 401(k) Accounts

When someone inherits a Roth 401(k), the five-year clock doesn’t reset; the beneficiary continues the original owner’s timeline. If the deceased had already completed the five years, distributions to the beneficiary are generally tax-free, because death is itself a qualifying event.² If the owner died before completing five years, the beneficiary has to wait out the remainder. Once five tax years have passed from the owner’s first Roth contribution, the earnings become eligible for tax-free treatment.

The 10-Year Drawdown Rule

For deaths occurring in 2020 or later, most non-spouse beneficiaries must empty the entire inherited account by the end of the 10th year following the year of the owner’s death.⁸ If the original owner satisfied the five-year requirement, the distributions taken under the 10-year rule come out tax-free. The 10-year rule forces the timing of withdrawals but does not change their tax character.

A narrow group of eligible designated beneficiaries, including surviving spouses, minor children of the deceased, disabled individuals, and beneficiaries not more than 10 years younger than the deceased, can stretch distributions over a longer period instead of following the 10-year rule.⁸

Spouse Beneficiaries

Surviving spouses have the most flexibility. A spouse can roll the inherited Roth 401(k) into their own Roth IRA, which shifts the analysis to Roth IRA rules. If the spouse already has a Roth IRA that has cleared its own five-year period, the rolled-over funds immediately benefit from that existing clock. A spouse can also leave the money in the inherited 401(k) plan if the plan allows it, or roll it into their own employer’s Roth 401(k). Lifetime RMDs no longer apply to the original account owner, but beneficiary RMD rules still apply to inherited designated Roth accounts.⁷
