RMD Beneficiary Designation Guide — How Beneficiaries Affect RMDs
How does my beneficiary designation affect my RMD and inherited account rules?
Your beneficiary designation on IRAs and retirement accounts is one of the most consequential financial decisions you will make. It determines who inherits the account, at what pace they must take distributions, and in some cases, your own RMD amount while you are still alive.
A spouse named as sole beneficiary has special privileges — including the option to roll the account into their own IRA, delaying RMDs until their own required beginning date. Non-spouse beneficiaries face stricter rules under the SECURE Act's 10-year rule.
Key RMD Rules
- 1Surviving spouse beneficiary: may roll over the inherited IRA into their own IRA, treating it as their own and delaying RMDs until their own required age.
- 2Surviving spouse may also elect to treat it as an inherited IRA, delaying distributions until the deceased would have turned 73 (useful if the surviving spouse is younger than 59½).
- 3Non-spouse eligible designated beneficiaries (minor children, disabled individuals, chronically ill, beneficiaries not more than 10 years younger): may use the Single Life Table.
- 4Non-eligible designated beneficiaries (most adult children, grandchildren): subject to the 10-year rule — full account must be emptied by December 31 of the 10th year after the owner's death.
- 5Trust beneficiaries: treated as individual or "see-through" trust; complex rules — consult an estate attorney.
- 6Charities and estates: not "designated beneficiaries" — account must be fully distributed within 5 years (if owner died before RBD) or by end of owner's remaining life expectancy.
Spouse Rollover vs. Inherited IRA Election
A surviving spouse who inherits an IRA has two choices: (1) Roll it into their own IRA — the account becomes theirs, RMDs start at their age 73, and they use the Uniform Lifetime Table. (2) Keep it as an inherited IRA — useful if the surviving spouse is under 59½ and needs distributions before 59½ without the 10% early withdrawal penalty. Once they turn 59½, most advisors recommend completing the rollover into their own IRA.
The 10-Year Rule for Non-Spouse Beneficiaries
Under the SECURE Act (2020) and clarifying regulations, most non-spouse beneficiaries who inherit in 2020 or later must empty the inherited account by December 31 of the 10th year after the owner's death. If the owner had already started taking RMDs, beneficiaries must also take annual RMDs during years 1–9 (in addition to clearing the account by year 10). Failure to take annual RMDs in those years results in a 25% penalty.
Common RMD Mistakes to Avoid
- ⚠Failing to update beneficiary designations after a life event (marriage, divorce, birth, death) — outdated designations can cause the wrong party to inherit.
- ⚠Naming a trust without ensuring it qualifies as a "see-through" trust — improperly structured trusts may accelerate distributions.
- ⚠Not naming a contingent beneficiary — if your primary beneficiary predeceases you and there is no contingent, the account goes to your estate and loses beneficiary RMD advantages.
