An Inherited IRA, or a Beneficiary IRA, is an account that is opened when someone inherits an IRA or employee-sponsored retirement plan after the death of the original owner. As a beneficiary, you cannot make additional contributions, but with an Inherited IRA the funds can remain tax-deferred, and you can generally withdraw money right away without a penalty. Inherited IRAs are typically opened for non-spouse beneficiaries, as spouses can transfer inherited assets directly into their own personal retirement accounts (although spouses can open an inherited IRA as well if they choose).
