I’m 74 years old (I used to be born Feb 2, 1948). My wife and I each worked for Aetna, but have retired and have 401(k)s from work which might be with Vanguard. I received her 401(k) as a spousal inheritance and maintain it in a separate account. I plan to take RMDs on her account but I’m unsure if I actually have the choice to take the RMDs based upon her age or my age. She had not begun taking RMDs on her account because she was not 72. Are you able to confirm which age (hers or mine) I should use for the primary RMD withdrawal, and by what date does that RMD should be taken? I think there’s a provision within the law that indicates that with spousal inheritance you don’t need to begin taking RMDs from an inherited account for a 12 months after the 12 months of death.

The date and amount of that first required minimum distribution (RMD) rely on what you choose to do with the inherited 401(k). The reply will vary based on whether you roll the funds into your personal 401(k) or IRA; transfer the account to an inherited IRA and take RMDs from it; transfer the cash into an inherited IRA and follow what’s called the 10-year rule; or do a Roth conversion. Here’s a better have a look at those options and what they mean for RMDs. (And should you need more help planning for RMDs or taxes in retirement, speak with a financial advisor.)

As a surviving spouse, you will have the choice of rolling the inherited 401(k) into your personal 401(k) or IRA. You would roll it into an existing account open open a recent IRA to receive the rollover.

When you go this route, the cash will probably be treated as yours and change into subject to the identical RMD requirements as should you had held it in your account all along. Since you’re 74 and not working, you would want to take an RMD by Dec. 31 and the quantity can be calculated using your age and the Uniform Lifetime Table. (But should you need more help calculating your RMDs, consider matching with a financial advisor.)

Transferring money to an inherited IRA is one way to manage an inherited 401(k).
Transferring money to an inherited IRA is one method to manage an inherited 401(k).

As a substitute of rolling it into your personal IRA, you would as a substitute transfer it into an inherited IRA. This has the advantage of allowing you to delay RMDs until the later of two deadlines:

In your case, it seems like this is able to will let you wait a few years before taking RMDs. So long as you are taking your first RMD by Dec. 31 of the 12 months your wife would have turned 73, you need to avoid penalties.
