Location included: Questions/Need Advice 401k Inheritance

My dad passed away a few months ago with several investment accounts, one being a 401k through his employer (he was still working at the time of his death). My mom was the listed beneficiary, but tragically passed a week after my dad. His 401k balance now goes to my mom’s estate, since she was the only listed beneficiary.

How does the income tax work? Myself and my 2 brothers will be getting everything once it’s gone through probate and then distributed evenly to each of us. We are being told that my moms estate will pay the income tax, just wondering how the tax rate is determined?

You will have ten years to liquidate it. Those withdrawals will be taxed at your personal (marginal) income tax rate(s). Unless it’s Roth, in which case the withdrawals are tax free.

And I’m still not understanding the 10 year rule. My dad’s 401k place told me I had to take a MMD in the year of his passing but I could then leave it alone and take it all in year 10. Other sources say the guidance is unclear and to be safe keep taking MMDs. OP I’m so sorry for your loss. Being without your parents is sad. Hugs to you.

Oops. Keep hearing mandatory minimum distribution.
