Updated July 28, 2026. Quick answer: An estate is not a designated beneficiary. Where the owner died before their required beginning date, that generally means a five-year emptying rule rather than ten — a materially worse outcome, and it happens whenever no beneficiary was named.
How accounts end up here
Usually by accident: no beneficiary form was ever completed, the named beneficiary died first and no contingent was listed, or the form named ‘my estate’ because that seemed tidy.
What it costs
| Named individual | Estate | |
|---|---|---|
| Emptying window (death before RBD) | 10 years | 5 years |
| Compression of income | Over a decade | Over half of one |
| Probate | Generally avoided | Account passes through the estate |
Compressing the same income into five years rather than ten reliably pushes more of it into higher brackets, and the account also loses the creditor and probate advantages of passing directly to a named person.
Beneficiary designations override the will. A carefully drafted will does nothing for an IRA whose beneficiary form is blank — the form is the controlling document, and checking it costs nothing.
