Spousal Rollover or Inherited IRA? The Choice Nobody Presents to a Widow

Same widow as the last piece: 76 the year after her husband dies, $36,000 of Social Security, $24,000 of pension, and his $480,000 IRA. This time she misses nothing. She takes every required distribution on the day it is due. The only thing she does not do is fill in one form in the months after the funeral, and that costs her more than the missed years did.

The form is the one that would make the account her own. A surviving spouse who is the sole beneficiary can retitle a husband's IRA in her own name, or roll it into an IRA she already has. Or she can leave it as an inherited account, which is what happens when nobody does anything. Custodians are allowed to assume that is what she wants. I wrote about the choice for HumbleDollar (the choice that feels like nothing); this page is the arithmetic, year by year.

Two tables, one birthday

A required minimum distribution is the account balance divided by a life-expectancy factor, and the factor comes from one of two IRS tables. A beneficiary uses the Single Life table. An owner uses the Uniform Lifetime table, which is built on two lives and so gives a bigger number at every age. At 76 the Single Life factor is 14.1 and the Uniform Lifetime factor is 23.7. Divide $480,000 by each and the first year's bill is $34,043 as a beneficiary and $20,253 as an owner.

That is the entire mechanism. Nothing about her, her income, or her account changes between the two columns except the name on the title.

Ten years on

Run both columns forward and the gap does not close. It widens, because the beneficiary's divisor falls faster and her balance shrinks under it. By 85 the inherited path has forced out $374,306 and the owner's path $246,281. Put those distributions on her actual return, alongside the Social Security and the pension, and the inherited path costs $30,555 more in federal income tax over the decade.

Be careful with what that means. She is not $171,434 poorer by age 85. She has not lost that money; it came out earlier and was taxed sooner. The extra $128,025 she was made to withdraw is hers, after tax, sitting in a bank or a brokerage account. What she has lost is the tax paid sooner than it needed to be, and a decade of compounding inside the IRA on money that was pushed out of it. That is a slower kind of damage than a penalty, and unlike a penalty it comes back every January for as long as she lives.

A floor, not a ceiling

The objection to taking the account as your own is usually that it ties the money up. It does the reverse. A required distribution is the least she must take. As owner she can withdraw $34,043, or $50,000, in any year she likes, and nobody asks why. What she leaves alone stays sheltered. The owner's smaller number gives her that choice. The beneficiary's larger number makes it for her, whether she needs the money that year or not.

Two cases that run the other way

The first is age at the survivor's end. A distribution from an inherited IRA is exempt from the 10% early-withdrawal penalty at any age, because it is paid on account of the owner's death. Take the account as your own and the ordinary rules return. A survivor under 59 and a half who expects to need the money has a real reason to leave the account as inherited, and for that survivor the exception outranks everything above. For a couple already past 59 and a half it will not apply.

The second is age at the other end, and it is the one the example above quietly assumes away. Where the survivor is the sole beneficiary, the start of distributions can be delayed until the end of the calendar year in which the deceased spouse would have reached his own applicable RMD age. If he was the younger of the two, that can push the first required distribution out by years. The widow in the example is 76 and so was her husband, which is why it does not arise for her.

This does not reverse the comparison. Once distributions do begin, a beneficiary is on Single Life, the faster table, and everything above applies again. What it changes is that the decision stops being a choice and becomes a sequence. There is no deadline for taking the account as your own, so a survivor in this position can hold it as inherited while the delay runs and then take it as her own before the delay ends. She gets the deferral first and the slower table afterwards.

The letter, again

The last piece was about the statement custodians send IRA owners every January and do not send for inherited accounts. This choice decides which side of that line she is on. Take the account as her own and the letter starts arriving. Leave it inherited and she is on her own to remember, on the schedule that costs more. The quiet option and the expensive option are the same option.

Check your own case

The free inherited IRA RMD calculator asks a surviving spouse one question the custodian's paperwork never puts plainly: whether the IRA has been treated or retitled as your own. Answer it both ways. With “yes” it applies the owner rules and the Uniform Lifetime table; with “no” it names the Single Life schedule and shows the divisor, the amount, and the years ahead. The two schedules side by side are the decision.

One thing it will not do. SECURE 2.0 added an election that lets a sole-beneficiary spouse be treated as the deceased for distribution purposes. It is called section 327. The rules for it are still in proposed form, and the calculator says so and stops rather than guess. Ask your custodian how they are handling it.

Decide it before you have to

None of this is hard. It is hard in the eight weeks after a funeral, which is when it gets decided, usually by nobody. If you are married and you both hold IRAs, settle it now while it is hypothetical. The question to talk through is whether the survivor would need the money soon, which is what the 59-and-a-half exception really asks. Then write down which way the survivor should go, put it with the will and the beneficiary forms, and look at it again as either of you nears the age your own distributions begin.

One thing to check on those forms while you are there. Every option on this page belongs to a spouse who is named directly as the sole beneficiary with an unlimited right to withdraw. Naming a trust instead fails that test even when the spouse is the sole beneficiary of the trust, and it takes the whole choice off the table. The trust is where the decision belongs. It is not where the IRA should point.

The beneficiary and owner paths, with their tax

RetireSmartIRA puts an inherited IRA on the same return as your Social Security, pension, and Medicare tier, so the two paths show what they cost, not just what they require.
