I inherited a 401(k) from my late wife. When do I need to take RMDs?

I am 74 years old (I was born on February 2, 1948). My wife and I both worked for Aetna, but are retired and have 401(k)s from work with Vanguard. I received that 401(k) as a spousal inheritance and maintain it in a separate account. I plan on taking RMDs on her account but I’m not sure if I have the option to take RMDs based on her age or my age. She didn’t start taking RMDs on her account because she wasn’t 72. Can you confirm what age (his or mine) I should use for the first RMD withdrawal, and by what date that RMD needs to be taken? I believe there is a provision in the law that states that with a spousal inheritance you don’t have to start taking RMDs from the inherited account until one year after the year of death.

First his date and amount Minimum distribution required (RMD) depends on what you decide to do with the inherited 401(k). The answer will vary depending on whether you roll the funds into your own 401(k) or IRA; Transfer the account to an inherited IRA and take RMDs from it; Transfer the money to an inherited IRA and follow the 10-year rule; Or do a Roth conversion. Here’s a closer look at those options and what they mean for RMDs. (And if you need to plan for RMDs or other help with taxes in retirement, Talk to a financial advisor.)

As a surviving spouse, you have the option to roll over the inheritance 401(k) In your own 401(k) or IRA. You can roll it into an existing account, open a new IRA to get the rollover.

If you go this route, the money will be treated as yours and subject to the same RMD requirements as if you had kept it in your account. Since you are 74 and no longer working, you will need to take an RMD by December 31 and the amount is calculated based on your age and Uniform Lifetime Table. (But if you need more help calculating your RMD, Consider contacting 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 way to manage an inherited 401(k).

Instead of rolling it into your own IRA, you can roll it into one Inherited IRA. This has the advantage of allowing you to delay RMDs until after two deadlines:

In your case, it sounds like it would allow you to wait a few years before taking RMDs. As long as you take your first RMD by December 31 of the year your wife would have turned 73, you should avoid the penalty.
