A Roth 401(k) can be rolled over into an existing or new Roth IRA or Roth 401(k). The rules are complex, so you must ensure you understand the five-year holding period, age limitations, whether the rollover is a qualified or non-qualified distribution, and any tax implications if taxes are triggered.
Key Takeaways
- Roth accounts are funded with after-tax dollars, and they grow tax-exempt.
- A Roth 401(k) can be rolled over to a new or existing Roth IRA or Roth 401(k).
- Transferring to a Roth IRA is generally the most desirable option because it facilitates a wider range of investment options.
- It’s best to move the money into an existing Roth IRA account if you have one due to a five-year rule that governs qualified distributions.
- Moving the funds to another Roth 401(k) may provide favorable tax treatment if you plan to withdraw the transferred funds soon.
Roth Rules
Roth IRAs and 401(k)s allow you to withdraw your contributions without penalty at any time, but to withdraw earnings or pre-tax deferrals without penalty, you must have had the account open for a minimum of five years and be 59½ (called a qualified distribution).
It’s important to understand that when making a non-qualified distribution, a ratio is used to calculate how much of it is earnings, and how much is contribution. This ratio is calculated by dividing the amount you’ve contributed by the total amount in the account.
For instance, imagine you’ve contributed $40,000, and your account balance is $42,000. Your ratio is $40,000 ÷ $42,000 = 0.95. You take a $5,000 distribution, so you multiply that number by your ratio. The contribution portion of this distribution is $4,762 (rounded up), so $238 of this distribution is earnings and taxable if non-qualified.
Rollovers are generally not subject to taxes, as long as one of the following methods is used.
Your Roth 401(k) Rollover Options
Your choices for a Roth 401(k) rollover are limited to Roth accounts. For example, you can transfer the funds from the Roth 401(k) into a Roth IRA, or you can roll the old Roth 401(k) into a new Roth 401(k) if available.
There are three ways you can roll a Roth 401(k) over:
- A direct rollover: Your plan custodian can cut a check made out to the new account, which you take or send to the new account custodian without penalty.
- Trustee-to-trustee: The old account and new account custodians handle the transfer for you without penalty. This is also called a direct transfer.
- 60-day rollover: You can take the funds out of the account as a distribution to place them in a new plan. You have 60 days to complete the transfer. If you don’t deposit the funds in another qualified retirement account within that time, you’ll pay any necessary taxes and fines.
Funds held inside 401(k)s are often well-protected against some legal judgments and from creditors.
Considerations When Rolling Into a Roth IRA
Roth IRA contributions can be withdrawn tax-free and penalty-free at any time regardless of age, but the rules for distributions of earnings vary. A qualified distribution from a Roth IRA meets the five-year rule and is also made at or after age 59½, after death, as the result of a disability, or for a first-time home purchase. These qualified distributions are free of both taxes and penalties.
Withdrawals of earnings from the account will be subject to both selective income taxes and a penalty if these conditions aren’t met. Income taxes will be levied pro-rata on earnings on your contributions, and a 10% penalty may apply to part of the distribution if you take a non-qualified distribution.
Note
IRAs frequently come with more investment options than 401(k)s. Your options in a 401(k) can sometimes be limited to mutual funds or a few different exchange-traded funds (ETFs), depending on the custodian, while you generally have more choices with an IRA.
Funds rolled from a Roth 401(k) into an existing Roth IRA that meets the five-year holding period inherit the Roth IRA’s five-year clock. However, this is not true if funds from a Roth 401(k) are rolled over to a new Roth IRA.
For example, assume that you opened your Roth IRA in 2016. You worked for your employer from 2019 to 2023 and then resigned. A full distribution from your Roth 401(k) rolled into the Roth IRA meets the five-year rule for qualified distributions because the Roth IRA that you’re rolling the funds into has existed for more than five years.
Considerations When Rolling Into a Roth 401(k)
The specific distribution rules from the new account will vary by the plan if you roll your old Roth 401(k) into a new Roth 401(k). Your new employer’s human resources department should be able to assist with this.
Some basic conditions apply, however. The number of years the funds were in the old plan should count toward the five-year period for qualified distributions if you decide to roll the funds from your old Roth 401(k) over to your new Roth 401(k) through a trustee-to-trustee transfer. The first employer must contact the new employer regarding the employee contributions being rolled over and confirm the first year they were made.
The five-year period would start again if you only did a partial rollover to the new Roth 401(k). You don’t get credit for the period the funds were in your old Roth 401(k).
Important
Speak with your tax or financial advisor about what may be best for you before making a decision. You might end up leaving the Roth 401(k) in your previous employer’s plan, depending on your circumstances and that plan’s rules.
How Does a Roth 401(k) Rollover Work?
You can contact your retirement plan manager and request a rollover. They should give ou a few options for how you want it to work, such as cutting a check and sending to the new retirement account custodian, transferring the balance to the new custodian, or cutting a check to you for the funds, which you must deposit within 60 days. Additionally, you can only rollover into another Roth-type account.
Does the 5-Year Rule Apply to a Roth 401(k) Rollover?
Yes. There are special circumstances such as a disability or a hardship withdrawal (which might be taxed).
What Are the Restrictions on a Roth 401(k)?
You can only contribute up to $23,500 and total combined contributions from you and your employer cannot exceed $70,000 in 2025 ($69,000 in 2024). If you’re 50 or older, you can contribute an additional $7,500 annually in catch-up contributions.
The Bottom Line
The rules for rolling over funds to a Roth 401(k) are complicated. Be sure to fully investigate the tax and other implications before you decide how to handle these funds after you leave the company whose plan held them—it’s best to consult a tax professional or advisor before rolling over your plan to make sure you’re not triggering unnecessary tax events.
