Roth 401(k) to Roth IRA Rollover: Tax-Free Transfer and the 5-Year Clock

If you have been contributing to a Roth 401(k) and are leaving your employer, rolling to a Roth IRA is one of the cleanest financial moves available — no tax bill, no penalty, and your money moves from a plan-constrained fund menu into the full flexibility of an IRA. But one detail trips people up: the Roth 401(k)'s 5-year holding period does not carry over to the Roth IRA. If you are rolling into a Roth IRA you have never contributed to before, that clock restarts.

Is the rollover taxable?

No. When you roll a Roth 401(k) — technically called a "designated Roth account" under IRC § 402A — directly to a Roth IRA, the entire amount moves tax-free.¹ Your contributions were made after-tax; the earnings have grown tax-deferred inside the plan. Neither are taxable on a qualifying rollover.

There is no mandatory withholding for a direct (trustee-to-trustee) rollover from a Roth 401(k) to a Roth IRA. The plan administrator will issue a Form 1099-R with Box 7 distribution code H ("direct rollover of a designated Roth account"). You report it on Form 1040 as a nontaxable rollover — no tax owed.

The 5-year rule: which clock governs?

The Roth IRA has a 5-year holding requirement before earnings can be withdrawn as part of a "qualified distribution" — that is, tax-free and penalty-free. Here is the exact interaction when a Roth 401(k) rolls in:

• Your Roth 401(k) has its own 5-year clock, measured from the first year a designated Roth contribution was made to that plan. After five years, your Roth 401(k) earnings are qualified under that plan's rules.
• On rollover to a Roth IRA, the Roth 401(k)'s holding period does not transfer. The IRS has confirmed this explicitly: "The period that the rolled-over funds were in the designated Roth account does not count toward the 5-taxable-year period for determining qualified distributions from the Roth IRA."²
• If you already have an existing Roth IRA — one you contributed to or converted into in any prior year — the Roth IRA's existing 5-year clock applies to all funds rolled in. If your Roth IRA was first opened in 2019, any rollover you make in 2026 lands in an account already past the 5-year mark.
• If you have never had a Roth IRA before and this rollover opens your first one, the 5-year clock starts on January 1 of the rollover year. Earnings are not tax-free for qualified distributions until five tax years have passed and you have met a triggering event — typically age 59½, death, or disability.³

What changes after rollover

Moving from a Roth 401(k) to a Roth IRA shifts several features — most of them in your favor:

Why roll over if Roth 401(k)s no longer have RMDs?

Before SECURE 2.0 took effect in 2024, the primary reason to roll a Roth 401(k) to a Roth IRA was to escape lifetime required minimum distributions. Roth 401(k)s had RMDs starting at age 73 (75 for those born 1960 or later); Roth IRAs had none. SECURE 2.0 § 325 eliminated Roth 401(k)/403(b)/TSP lifetime RMDs for distributions after December 31, 2023 — removing the main forcing function for rollover.⁴

Three reasons the rollover is still worth doing:

1. Investment flexibility. Most employer plans offer a constrained fund menu. A self-directed Roth IRA gives access to the full investment universe — individual stocks, bonds, ETFs, REITs, international funds. On a $250,000+ balance, a 0.5% reduction in annual expense ratio compounds to tens of thousands of dollars over 20 years.
2. Roth IRA contribution room. Rolling over a Roth 401(k) does not count against your annual Roth IRA contribution limit. If your MAGI falls below the phaseout, you can still contribute $7,500 ($8,600 if 50+) per year to the same Roth IRA you just funded with a rollover — the two limits are independent.
3. Estate planning flexibility. Roth IRAs offer more granular beneficiary designation options, including per-stirpes elections and see-through trust strategies. See IRA Beneficiary Designations After Rollover for the full picture on the 10-year rule and EDB exceptions.

One reason to pause: ERISA creditor protection. Your Roth 401(k) carries unlimited federal protection against non-bankruptcy creditor claims. After rolling to a Roth IRA, protection becomes state-specific. If you are a physician, business owner, or otherwise face elevated professional liability risk, discuss the timing with a planner before you initiate the rollover.

Pre-rollover checklist

1. Confirm your designated Roth balance. Ask your plan administrator for the "designated Roth account" balance separately from any pre-tax balance. Many workers have both; each must roll to the correct destination.
2. Find your Roth IRA first-contribution year. Log into your IRA custodian and find the oldest Roth IRA you have ever held. The year of your first contribution (or conversion) is your 5-year clock start — it applies to all future rollovers into that IRA.
3. Check unvested employer match. Your own Roth 401(k) contributions are always 100% vested. But employer match contributions may vest on a schedule. An unvested employer match stays in the plan — you are leaving that money behind on separation. Know the number before you finalize the rollover.
4. Outstanding 401(k) loans. An unpaid loan typically becomes due within 60–90 days of separation. Under the QPLO (Qualified Plan Loan Offset) rules from SECURE 2.0, you have until your federal tax filing deadline to roll over an offset amount to an IRA — but the remaining loan balance does not roll. Resolve loans before separation when possible.
5. Verify no non-governmental 457(b) assets are mixed in. Non-governmental 457(b) balances cannot roll to an IRA under IRC § 457(e)(1). Keep your rollover scoped to the 401(k) or 403(b) designated Roth account only.

How to execute the rollover

1. Open a Roth IRA at your target custodian if you do not already have one. Note the calendar year — this starts your 5-year clock if you have no prior Roth IRA.
2. Request a direct trustee-to-trustee rollover from your plan administrator. Specify that you want the designated Roth subaccount rolled directly to your Roth IRA. Do not take a check — the indirect rollover path subjects the gross amount to mandatory 20% federal income tax withholding (even though the distribution is not taxable), and you must make up the withheld amount from outside funds within 60 days to avoid a partial distribution.
3. Provide your Roth IRA account number to the plan administrator. Most process direct rollovers within one to three business days; mailed checks can take one to two weeks.
4. Verify the amount matches your designated Roth balance. Once deposited, check that the custodian has coded it as a rollover contribution (not a regular contribution, which would count against your annual limit).
5. Your plan will issue a Form 1099-R in January with distribution code H. Report it on Form 1040 line 5a/5b — full amount on line 5a, zero taxable on line 5b. No tax is owed.
