Rolling a Roth 401(k) to a Roth IRA? Watch Out for This 5-Year Rule

Does Rolling a Roth 401(k) Into a Roth IRA Reset the Five-Year Clock?

If you've been building a Roth 401(k) for years and you're planning to roll it into a Roth IRA when you leave your job, there's a five-year rule that catches a lot of people off guard. The years you spent building that Roth 401(k) don't automatically come with you to the Roth IRA.

In this video, we walk through exactly how the five-year rule works for Roth IRAs and Roth 401(k)s, why the two accounts pay out money differently, and the simple planning move that can help protect the tax-free treatment of your Roth earnings before you make the rollover.

This topic connects to broader Roth planning decisions. You may also find our video on whether Roth conversions are a smart move or a tax trap helpful for understanding how the Roth conversion five-year rule works separately from the rollover rule covered here.

What Makes a Roth IRA Withdrawal Qualified and Tax-Free?

For earnings in a Roth IRA to come out completely tax and penalty-free, what the IRS calls a qualified distribution, two conditions generally need to be met. First, you're age 59 and a half or older, or the withdrawal qualifies because of death, disability, or an eligible first-time home purchase. Second, you've satisfied the Roth IRA's five-year qualified-distribution rule. The first-time home purchase exception is subject to a $10,000 lifetime limit.

For a Roth IRA, the five-year period for qualified distributions generally begins January 1 of the tax year for which you first made a contribution to any Roth IRA, or the tax year of your first Roth conversion. All of your Roth IRAs share this same qualified-distribution five-year period, even if you open additional accounts with different custodians later.

Why Roth IRAs and Roth 401(k)s Pay Out Money Differently

A Roth IRA follows ordering rules. Regular Roth IRA contributions come out first, followed by conversion and rollover amounts, and earnings come out last. This generally allows you to withdraw your regular Roth IRA contribution basis tax-free and penalty-free at any age, regardless of whether the five-year qualified-distribution rule has been met. Separate rules can apply to certain converted amounts.

A Roth 401(k) doesn't work that way. If your withdrawal from a Roth 401(k) isn't qualified, the distribution is generally treated pro-rata, meaning it's a proportional mix of your contributions and earnings. You can't simply choose to withdraw contributions first.

This distinction is at the heart of why rolling a Roth 401(k) into a Roth IRA before taking money out can matter for someone whose Roth 401(k) hasn't met its own five-year requirement.

What Are the Three Different Roth Five-Year Rules?

Roth IRAs, Roth 401(k)s, and Roth conversions have different five-year requirements. Understanding which rule applies can help you avoid confusion when planning a rollover or withdrawal.

Important: Your Roth 401(k)'s five-year participation period doesn't transfer to a Roth IRA. The Roth IRA uses its own qualified-distribution clock. However, whether the Roth 401(k) distribution was qualified or nonqualified affects how the rolled-over amount is treated under Roth IRA withdrawal rules.

An Illustrative Example: The $120,000 Roth 401(k)

Say you're 63 and retiring. Your company added a Roth option three years ago, so your Roth 401(k) hasn't met its five-year rule yet. The account is worth $120,000: $90,000 you contributed and $30,000 of growth. You need $40,000.

If you withdraw $40,000 directly from the Roth 401(k), 25% of that distribution, or $10,000, would be earnings under the pro-rata rule. Because the distribution isn't qualified, those earnings would generally be taxable. Assuming the entire $10,000 is taxed at a 24% federal rate, that could mean approximately $2,400 in federal income tax.

Now consider what happens if you complete a direct rollover of the Roth 401(k) into a Roth IRA before withdrawing the $40,000. Assuming the rollover is completed properly, the Roth 401(k)'s $90,000 contribution basis is treated as basis available under the Roth IRA's distribution ordering rules, while the $30,000 of earnings retains its earnings character.

Because Roth IRA ordering rules generally allow basis to be withdrawn before earnings, the $40,000 withdrawal in this example could come entirely from basis. That means no federal income tax on the withdrawal, even though the Roth IRA's five-year qualified-distribution requirement may not yet have been satisfied.

Illustrative example only. Assumes a nonqualified Roth 401(k) distribution, a properly completed direct rollover, sufficient available Roth IRA basis, a 24% federal tax rate on the earnings portion of a direct plan withdrawal, and no state income tax. Actual results depend on account history, distribution ordering, and individual circumstances. Consult your tax advisor.

The Trap: Your Roth 401(k) Years Don't Transfer to the Roth IRA

Here's where people get caught. A Roth 401(k) has its own five-year participation period. When you roll it into a Roth IRA, those years don't carry over for purposes of the Roth IRA's five-year qualified-distribution rule. Instead, the Roth IRA's own clock applies.

Go back to the 63-year-old in the example. Their Roth 401(k) hasn't met its five-year rule, and they've never opened a Roth IRA. They complete a direct rollover in January 2026. The earnings portion of the nonqualified Roth 401(k) distribution becomes earnings in the Roth IRA, and the Roth IRA's five-year clock begins January 1, 2026. Assuming no earlier Roth IRA contribution or conversion, qualified withdrawals of those earnings generally become available beginning January 1, 2031, because the individual is already over age 59 and a half.

But if that person had first established a Roth IRA for tax year 2021, the five-year requirement would already be satisfied by 2026. Since they're also over age 59 and a half, distributions from the Roth IRA could be qualified, including distributions attributable to the rolled-over earnings.

What If Your Roth 401(k) Already Meets Its Five-Year Rule?

Here's an important distinction: Not everyone rolling a Roth 401(k) into a Roth IRA faces the same five-year issue.

If you're at least age 59 and a half and your Roth 401(k) has satisfied its five-year participation requirement, the distribution is generally qualified. When you roll that qualified distribution into a Roth IRA, the entire amount, including the earnings, is generally treated as basis for Roth IRA withdrawal-ordering purposes.

That means you can generally withdraw the amount rolled over without additional income tax, even if your Roth IRA hasn't yet satisfied its own five-year requirement. The Roth IRA's five-year clock still matters for earnings generated after the rollover.

Two Things to Do Before You Roll Over

First, check whether you've already established a Roth IRA. If you have one, determine the tax year your five-year qualified-distribution period began. That date helps determine when earnings can be withdrawn tax-free after a rollover.

If you haven't opened a Roth IRA yet, there may still be an opportunity to start the clock earlier than you think. Eligible contributions made between January 1 and the tax-filing deadline can generally be designated for the previous tax year. For example, a qualifying Roth IRA contribution made by April 15, 2027, for tax year 2026 would establish a five-year period beginning January 1, 2026.

Roth IRA contributions require eligible compensation and are subject to annual contribution limits and income restrictions. If your income is too high for a direct contribution, other strategies may be available, but they require additional tax planning. Talk with your advisor or tax professional before making a contribution or rollover.

Second, remember that Roth conversions have a separate five-year rule. The Roth IRA qualified-distribution rule determines whether earnings can be withdrawn tax-free when the other qualification requirements are met. The separate conversion five-year rule generally concerns potential 10% early-distribution penalties on certain converted amounts withdrawn before age 59 and a half. Each conversion has its own five-year period, so it's important not to confuse these rules.

One other change worth knowing: Beginning in 2024, Roth 401(k)s generally are no longer subject to required minimum distributions during the original account owner's lifetime. That means avoiding lifetime RMDs is no longer, by itself, a reason to roll a Roth 401(k) into a Roth IRA.
