A Non-spouse Beneficiary is someone who inherits a retirement account, like an IRA or 401k, but is not the spouse of the original account owner. Unlike spouses, non-spouse beneficiaries can’t roll the account into their own name and may have different rules for withdrawing the money. In most cases, they must take the funds out within a certain number of years, depending on the type of account and when the original owner passed away. These rules are meant to ensure the money doesn’t stay in the account indefinitely and that taxes are eventually paid on it.
