And Basically, it has to be on account of the death. Meaning if the money comes to the beneficiary directly from the decedent's qualified employer plan account or from the decedent's IRA, fine, no 10% tax at any age. But if the beneficiary rolls it over, even without commingling with any other assets, and then later takes a distribution from the rollover account, it may, in fact, still be the money left to the beneficiary by the decedent, plus a little earnings, but it does not enjoy the death benefit exception from the 10% tax.
