Tax Tips: Should You Rollover Your Roth 401k into a Roth IRA?

Paul Hansen

If you have retirement funds held in the Roth 401k plan of a prior employer (or a similar employer sponsored, after-tax retirement account such as a Roth 403b or Roth 457 account), you might want to consider rolling those after-tax retirement accounts directly into a Roth IRA. While there are many similarities to the tax-free investment growth that these accounts offer, it is important to understand the differences that exist before making a rollover.


  • Roth IRAs typically provide a broader selection of investment options than those offered in a Roth 401k.
  • Roth IRAs do not require the original owner to take minimum annual distributions once they reach age 70½, but a Roth 401k is subject to Required Minimum Distributions (RMDs) even though the distributions are tax exempt (this eventually forces you to start moving money out of a tax sheltered account and into accounts where future growth and earnings will be subject to tax.)
  • Roth IRA earnings distributions prior to age 59½ could qualify for exemptions from the 10% premature withdrawal penalty in some circumstances that are not available for Roth 401k distributions (ex. first-time home buyers, etc.)


  • Roth 401k plan management fees might be lower than fees related to the management of a Roth IRA if you pay an advisor to manage the account for you.

Don’t forget to consider the five-year rule!

Another important aspect of converting a Roth 401k into a Roth IRA is the impact it could have on the five-year rule for distributions. What is this five-year rule? In order for any distribution of earnings from either a Roth 401k or a Roth IRA to be a “qualified” distribution that is exempt from income tax (and possibly a 10% premature withdrawal penalty), the distribution must take place after the Roth has been open for at least five tax years (even if the owner is older than 59½, dies, is disabled, or qualifies for some other exemption to the age 59½ requirement.)

Here are a few key points related to this five-year rule:

  • The five-year “clock” begins January 1st of the tax year that you first open the account. This means that if you first established a Roth IRA in April of 20X1 in order to make a 20X0 tax year contribution, the Roth IRA would be considered open on January 1, 20X0.
  • When you roll a Roth 401k balance into a Roth IRA, it is subject to the five-year clock of the Roth IRA account (even if the Roth 401k has been open much longer.)

One way to ensure that you don’t run afoul of the five-year requirement on a rollover is to open the Roth IRA account and make a minimal contribution to it at least five tax years before you know you will take a distribution from the account. Then, when you roll a Roth 401k into it later, the five years will have already passed, and the five-year holding period will be satisfied. In fact, as long as you have any Roth IRA open for at least five years (under your name and Social Security number), you can roll the Roth 401k into another Roth IRA and it will meet the five-year requirement based on having another pre-existing Roth IRA.
