Inheriting a retirement account can be complicated.

With a retirement account that you opened, you’re referred to as the original owner. You can contribute to this portfolio, manage it as you see fit, and leave the money in place subject only to required minimum distributions (RMDs) in some cases. When you inherit a retirement account, the rules change. You cannot make new contributions and, depending on your relationship to the original owner, you may need to withdraw this money within 10 years of receiving it.

With an inherited account, the most important distinction is between “designated beneficiaries” and “eligible designated beneficiaries.” An eligible designated beneficiary has far more leeway to manage the inherited account as they see fit, with potentially significant tax implications. 

For example, say that your husband has passed, leaving you his 401(k) with $615,000 in it. As a spousal beneficiary, you have a broad range of options for how you can manage this money. And if you need guidance specific to your situation, you can always consult with a financial advisor.

Beneficiaries and Inherited Accounts

Inheriting a tax-advantaged retirement account is subject to different rules than inheriting a standard investment portfolio. Most notably, you cannot make additional contributions to this account. Beyond that, the IRS has rules for how long you can leave this money in place based on which category of heir you fall into: spousal beneficiaries, eligible designated beneficiaries or designated beneficiaries. 

Readers should note that we will discuss the rules for accounts inherited in 2020 and later, as those rules were changed in the SECURE and SECURE 2.0 Acts. These rules also apply to inherited Roth accounts, even though a Roth portfolio is typically exempt from RMD rules.

Spousal Beneficiaries

Spousal beneficiaries are considered a subcategory of eligible designated beneficiaries. You are a spousal beneficiary if the retirement account belonged to your spouse at the time of their death. 

If you are a spousal beneficiary, you have three options. You may:

  • Take RMD distributions from the account, based on either your life expectancy or the original owner’s life expectancy
  • Withdraw the entire amount within 10 years (the 10 Year Rule)
  • Roll the account into your own IRA

The availability of these options can depend on the status of this retirement account at the time of your spouse’s death. Rolling inherited funds into your own IRA will not change the rules of that account. You can continue making contributions to the IRA as usual, regardless of the inherited assets. Consider speaking with a financial advisor about your specific case. The right financial advisor can help you navigate the rules and execute your strategy.

Eligible Designated Beneficiaries

An eligible designated beneficiary is someone who meets one of a handful of specific qualifications. This includes:

  • The spouse of the deceased (see above)
  • A minor child of the deceased
  • A disabled or chronically ill individual
  • An individual no more than 10 years younger than the deceased

If you are an eligible designated beneficiary other than a spouse, you have the following options:

  • Take RMD distributions based on the longer of either your life expectancy or the deceased’s life expectancy
  • Withdraw the entire amount within 10 years (the 10 Year Rule)

You cannot roll this account into another IRA. If you withdraw the funds under the 10 Year Rule, you must take out the assets and trigger a tax event. 

Designated Beneficiaries

Designated beneficiaries are all heirs who are not considered eligible designated beneficiaries. Put another way, if you do not meet one of the categories above, you are a designated beneficiary. These heirs must follow the 10 Year Rule, meaning that they must withdraw all assets from the inherited account within 10 years of inheriting it.
